Transform Milwaukee 2-1 Industry Structure Analysis
Section 2 – Industry Structure Analysis The following overview of the region’s industry structure considers quantitative measures of industry scale and
performance including total employment, compensation, income, specialization, output and geographic
concentration. Understanding the local and regional economy from these industry perspectives provides one
means for determining potential economic niches, strengths and weaknesses of the industrial corridor at the
heart of the Transform Milwaukee Initiative. Ultimately, insights to the local and regional industry structure
will inform workforce development efforts and guide business attraction, retention and expansion strategies
for the area.
When considering the local and regional industry structure, it is important to understand how industries
interact with each other and connect to the larger external economy (Figure 2.1). Export industries have often
been viewed as a vital component of a region’s economy given their ability to attract outside dollars and in
turn spur economic growth. While manufacturing and large-scale agriculture are commonly recognized as
export industries, any industry with a sufficient dependence on external markets may be an export industry.
Furthermore, industries that bring federal payments or visitors into the community also transfer external
dollars to local establishments (i.e. some categories of health care, procurement contracting, and tourism).

Linkage Industries – Industries that provide support to other firms in the local market, but can also service the non-local market (e.g.
business services, transportation, distribution, etc.)
Export Industries – Industries that export goods and services to markets outside the region, bringing new revenues into the local
economy (e.g. manufacturing, large scale agriculture, knowledge, etc.)
Population Driven Industries – Industries with demand largely driven by a community’s population base rather than by business-to-business
demand (e.g. retail, hospitality, personal services, real estate, etc.).

Transform Milwaukee 2-2 Industry Structure Analysis
Although economic development strategies often overemphasize export-dependent sectors, export industries
remain a focus of this analysis given two fundamental issues mentioned in the Introduction to this study. First,
the population in Milwaukee County has remained largely unchanged over the last 30 years. Consequently,
there is little additional demand being generated locally for population-driven industries.1 Second, and more
importantly, a particular challenge facing central city economies is a lack of connections to external markets
for both firms and employees. Building export industries in the central city provides one strategy for
generating ties between Milwaukee’s industrial core and regional, national and international economies.
Nonetheless, linkage industries and population-driven industries should not be overlooked as potential
contributors to growth as the availability and quality of these industries are important to export-driven
industries and contribute to the quality of life in a community.
Using the framework of industries in Figure 2.1, the following analysis assesses the scale and economic
contributions of export, linkage and population-driven industries within Milwaukee’s industrial core. While the
number of employees within a given industry is an important consideration when assessing the regional
economy, note that export-driven industries often have a smaller share of total employment than linkage
industries or population-driven industries. Consequently, the analysis also considers other measures of
industry scale including employee compensation, labor income, specialization, agglomeration and output.
As mentioned, one goal of this industry structure analysis is to determine those industries that may be well-
suited for development through expansion, attraction or retention efforts in Milwaukee’s Industrial Corridor.
While the areas surrounding the 30th Street Industrial Corridor, the Menomonee Valley, the Port of Milwaukee
and the 440th Air Base Redevelopment Area are of primary interest, detailed industry data are not available for
these geographic areas. Consequently, some measures rely on figures from the 11 zip codes that encompass
these four employment centers.2 The 11 zip code region used in the analysis will be referred to as the
Milwaukee Industrial Corridor hereafter.
Industry figures also are reported for the seven-county Milwaukee 7 (M7) Region. Industry data on the M7
Region provide perspectives on the differences or similarities between the Milwaukee Industrial Corridor and
the broader regional economy. Figures on the M7 Region may also suggest regional economic advantages or
opportunities that can be leveraged by local efforts in the Industrial Corridor. By design, the analysis is broadly
conducted with industry measures reported primarily at the three-digit North American Industrial
Classification System (NAICS) level. Note that aggregating industries at the three-digit NAICS level allows for a
somewhat detailed analysis of industry structure, but some potential economic niches and strengths may exist
at more refined levels of industrial classification. Furthermore, economic niches and strengths often do not
neatly follow industrial classification schemes. Other potential opportunities are considered using additional
assessment measures throughout this study.
The data used to produce the analysis are based on two sources:
1. Quarterly Census of Employment and Wages (QCEW) – QCEW is a cooperative program involving the
Bureau of Labor Statistics (BLS) and the State Employment Security Agencies (SESAs) and serves as a near
1 Despite the population trends, there may be some opportunities to fill existing, unmet demand for population driven industries in the
community. 2 These 11 zip codes include: 53203, 53204, 53205, 53206, 53207, 53208, 53209, 53210, 53215, 53216 and 53233.

census of monthly employment and quarterly wage information. Employment data under the QCEW
program represent the number of workers covered by unemployment insurance who worked during, or
received pay for, the pay period including the 12th day of the month. Excluded are members of the armed
forces, the self-employed, many proprietors, domestic workers, unpaid family workers, and railroad
workers covered by the railroad unemployment insurance system. As the QCEW data are subject to
disclosure restrictions, some data may be suppressed to maintain the confidentiality of employers;
2. IMPLAN (Impacts for PLANning) – IMPLAN is an input-output (IO) economic modeling software package.
Input-output models are widely used for measuring economic impact, but can provide a powerful tool for
examining strengths and weaknesses in the region’s economy. Using IMPLAN is advantageous as it allows
for the interactions among industries to be modeled and provides estimates for proprietors and
employment figures otherwise suppressed in QCEW figures. A more complete description of the input-
output model structure is included in Appendix 2A.
The figures in this section rely on 2010 annual data, which are the most current annual figures available at the
time of analysis. Consequently, readers should be aware that figures might not reflect recent changes in local
and national industries. Readers should also note that figures from IMPLAN and QCEW will differ somewhat
for a variety of reasons:
Government classification – IMPLAN classifies employees of all public-sector institutions under a general
government employment category. In contrast, QCEW reports government employees under their
respective industry categories. For instance, employees at county government-operated hospitals and
nursing homes would be reported within the health care sub-sector by the QCEW program and under the
government category in IMPLAN. These differences are particularly important for employment figures in
the educational services industry sub-sector;
Definition of employees – While QCEW only reports employees covered by unemployment insurance,
IMPLAN estimates include both covered employees as well as non-covered employment such as
proprietors, farm laborers and the self-employed;
IMPLAN estimation procedures – IMPLAN relies on a variety of public data sources (Bureau of Economic
Analysis regional accounts, Census Bureau’s County Business Patterns, Quarterly Census of Employment
and Wages, Economic Census, etc.) to estimate data that are suppressed by federal reporting
requirements;
Industry classifications selected by the business owner – The datasets rely on how a business owner
classifies his or her establishment. Each business is classified into a single NAICS category based on the
primary good or service sold. As a result, businesses that sell a variety of goods or provide multiple
services are only classified under one NAICS category. Descriptions and additional information on NAICS
codes and definitions are available at: http://www.census.gov/eos/www/naics/.
Given these differences, less emphasis should be placed on the precision of specific numbers. Instead, overall
trends and patterns present in the data are used to provide guidance and triangulate findings.

Employment by Industry
The top 50 Milwaukee Industrial Corridor industries as ranked by total employment are a mix of export-driven,
linkage and population-driven industry types (Table 2.1). Note that construction (NAICS 23) and wholesale trade
(NAICS 42) are reported at the two-digit NAICS level of industry aggregation. Consequently, the rankings and
apparent scale of these two industries may be overstated relative to other private sector industries reported at the
three-digit NAICS level. Comparing the figures for each industry suggests a number of similarities and differences
between the Milwaukee Industrial Corridor and the M7 Region:
Government and non-classified employment is listed as the largest employment category. Again, IMPLAN data
classify all public-sector employment under the government and non-classified employment category (NAICS
92). Consequently, it is not uncommon for government to appear as the largest employer in a region when
using IMPLAN data. For the figures in Table 2.1, IMPLAN’s government aggregation scheme is particularly
relevant as employees of public school systems and higher education institutions are included here rather than
under educational services (NAICS 611);
As population-driven industries tend to account for large shares of employment in a region (see Figure 2.1), it
should not surprise that many of these industries are among the largest employers in Milwaukee’s Industrial
Corridor and the M7 Region. Specifically, social assistance, health care, food services and drinking places,
private educational services, personal services and retailers dominate the top 25 employment categories.
Importantly, several of these industries also have large numbers of part-time employees which may inflate their
employment figures;
Several manufacturing sub-sectors are among the largest employers including the manufacturing of food,
computer and electronic products, fabricated metal products, machinery, chemicals, primary metals, electrical
equipment, printing and beverages. Several of these categories also have similar or even greater shares of
employment in the M7 Region, suggesting the regional importance of these industries as well;
A number of linkage industries providing business support services are highly ranked in employment, including
administrative and support services (NAICS 561); professional, scientific and technical services (NAICS 541); and
truck transportation (NAICS 484). Compared to the broader M7 Region, these three industries account for
lower shares of total employment in the Corridor;
Management of companies and enterprises (NAICS 551) is highly ranked in the Corridor, accounting for over
5,600 employees and 3.3 percent of total employment. Employment in this category is driven by offices of
holding companies, headquarters and management subsidiaries (such as offices for MillerCoors and Rockwell
Automation). While this category is somewhat inclusive of many industries, it does show the importance of
company headquarters and regional offices to the local economy. Understanding the companies in this
category is also important to revealing strengths in regional industry clusters;
Retail sub-sectors listed among the top 50 employers include food and beverage stores, motor vehicle and parts
dealers, general merchandise stores, miscellaneous store retailers, clothing and clothing accessory stores, non-
store retailers, health and personal care stores, and building material and supplies dealers. Every retail
category shows a higher share of employment in the M7 Region than in the Industrial Corridor. The
disproportionate shares may be indicative of overall population and demand distributions, but could also
suggest a supply gap in the Corridor arising from local consumer demand not being met sufficiently by local
retail establishments. Further analysis is necessary to verify these conditions.

Transform Milwaukee 2-6 Industry Structure Analysis
Compensation and Total Labor Income by Industry Employee compensation (Table 2.2) and total labor income (Table 2.3) provide different perspectives on how
industries return income to workers in the local economy. Employee compensation represents the total
payroll cost of employers and includes both wages and benefits paid to employees. In contrast, total labor
income includes proprietor income in addition to employee compensation. Proprietor income is paid to
individuals in the forms of self-employment income and business profits (depending on a firm’s ownership
structure). Differences in average employee compensation and total labor income per job often can be
attributed to an industry’s wage, revenue or ownership arrangements. Note that not all compensation and
labor income generated by businesses in the Milwaukee Industrial Corridor or the M7 Region remains in these
areas, as workers and business owners may commute from elsewhere.
Similar to their total employment rankings, the industry categories of government and non-classified
establishments; hospitals; ambulatory heath care; and private educational services also rank highly in
employee compensation and total labor income (Table 2.3). In contrast, other industries that account for
high shares of employment contribute lower shares of income and compensation. These industries
include social assistance; food services and drinking places; and administrative and support services. The
diminished influence of these industries on local income reflects their lower levels of average
compensation and labor income per employee;
Average compensation per employee is an important consideration when crafting economic development
policies. In particular, medium-to-high compensation levels are often a prerequisite of policies designed to
encourage the growth of local industries. More than half of the industries (28 of 50) ranked in Table 2.2
have mean employee compensations above the overall average for all industries in the Milwaukee
Industrial Corridor. Industries with above average compensation are dominated by professional, technical
and management services; financial and insurance services; health care; information; utilities; and
manufacturing. In contrast, industries with low average incomes largely are found in retail, personal
services, and hospitality-related industry categories. The low average compensations in these industries
partially reflect a prevalence of part-time positions, as well as overall lower skill requirements;
Manufacturing is featured prominently among the top 50 industries for both employee compensation and
labor income, with 11 sub-sectors found in both Table 2.2 and Table 2.3. These industries also show high
average levels of compensation and labor income, with only food manufacturing (NAICS 311) and printing
and related support activities (NAICS 323) showing average compensations below the overall average for
all sectors in the Industrial Corridor. Even so, the compensation levels of these two manufacturing sub-
sectors are only slightly below the mean;
Average employee compensation for all industries in the Milwaukee Industrial Corridor is six percent
higher than the average for the M7 region. The higher average compensation is driven partly by a larger
presence of several industries located in the Industrial Corridor including management of companies and
enterprises; private educational services; insurance carriers, utilities; government; hospitals; and computer
and electronic product manufacturing. Nonetheless, a number of key industries in the M7 Region have
higher average compensations than their Corridor counterparts, including most manufacturing categories;
wholesale trade; ambulatory health care services; and administrative and support services.

Industry Location Quotients
A location quotient (LQ) provides one measure for analyzing industry concentration and specialization in an
area. Location quotients are calculated by comparing a given industry’s share of total local employment to the
same industry’s share of overall national employment:
The critical value for a location quotient is 1.0. An LQ of 1.0 means an area has the same proportion of local
employment in an industry as the nation. An LQ greater than 1.0 denotes that an area’s share of employment
in a given industry is greater than its national share. Conversely, an LQ less than 1.0 indicates an area’s
employment in an industry is below the national percentage. Due to accuracy issues with employment data,
location quotients between 0.75 and 1.25 are generally considered not to be significantly different from 1.0.
A location quotient of 1.0 suggests that the local level of demand for that good or service is satisfied by local
industries (supply equals demand). Location quotients greater than 1.0 are important as they imply that an
area has a specialization in a given industry. More specifically, an LQ greater than 1.0 suggests that an industry
is producing more goods or services than can be consumed locally. These goods and services are in turn
exported out of the region, bringing outside dollars into the area (i.e. they have an export-orientation).
Conversely, an LQ less than 1.0 suggests that local industries are not meeting local demand (demand is greater
than supply and the good or service must be imported).
Note that differences in local demand preferences compared to national conditions, or the efficiency of a local
industry, have the potential to skew the results of a location quotient analysis. Furthermore, the Milwaukee
Industrial Corridor and M7 Region should not seek to satisfy all local demand internally, as certain industries
are better suited for other locations or simply are not feasible within the local economy. Even so, LQs serve as
one basis for examining potential export industries and determining specialization within the area.
The top 50 Milwaukee Industrial Corridor industries are ranked by their location quotients at both three-digit
(Table 2.4) and four-digit (Table 2.5) NAICS levels of aggregation. Compared to the prior measures of
employment, compensation and labor income, location quotients present a different perspective of the local
and regional economy:
Many population-driven industries previously showing high overall shares of employment, compensation
and total labor income are ranked much lower when using location quotients. For instance, the
government and non-classified establishment category (NAICS 92) has a location quotient below 1.0 (e.g.
employment share below the national average) and is ranked in the bottom third of the industries listed in
Table 2.4. However, some locally-serving industries remain highly ranked with location quotients above
1.25 including: social assistance; hospitals; private educational services, ambulatory health care service;
performing arts, spectator sports and related industries; and broadcasting. Note that the high location
quotients for health care-related industries are not driven by a concentration of hospitals and other

medical facilities in the 30th Street Industrial Corridor, the Menomonee Valley, the Port of Milwaukee and
440th Air Base Redevelopment Area. Instead, these facilities are located in other portions of the broader
zip codes that are used to create the Industrial Corridor area used in the analysis. Similar conditions and
influences are found in the broadcasting industry and the performing arts, spectator sports and related
industries category. Furthermore, the high LQ for social assistance likely reflects the income and poverty
levels noted in Section 1;
As manufacturing tends to be an export-oriented sector, it is not surprising that many of the industries
with large location quotients are manufacturing categories. At the three-digit NAICS level, nine
manufacturing categories in the Milwaukee Industrial Corridor have location quotients above or well
above 1.25 (Table 2.4). Several of these categories are relatively small in terms of employment (e.g. leather
and allied products), but others such as computer and electronic product manufacturing, food
manufacturing, machinery manufacturing and fabricated metal product manufacturing have notable
employment levels in both the Industrial Corridor and throughout the overall M7 region. Furthermore,
electrical equipment, appliance and component manufacturing has a very high location quotient and
employment base in the overall M7 region, despite a somewhat smaller presence in the Corridor;
When measuring location quotients at the more detailed four-digit NAICS level, all top 50 industries in the
Industrial Corridor have an LQ above 1.25 (Table 2.5). Again, a large share of these industries are classified
under manufacturing with many categories related to primary metals; electrical equipment, appliance and
components; fabricated metal products; food products; and machinery.
Equally important as those industries showing large location quotients are categories not listed in Table 2.4
and Table 2.5 due to their low location quotients. Among the Industrial Corridor industries with low
location quotients are many retail categories including: grocery stores; general merchandise stores;
electronics and appliance stores; gasoline stations; furniture and home furnishing stores; sporting goods,
hobby, toy and book stores; and clothing and accessory stores. While a large amount of retail would not
necessarily be expected in industrial areas, these location quotients could further suggest that local retail
spending potential could be leaking from the Corridor. Moreover, these retail categories show location
quotients near or above 1.0 for the greater M7 Region suggesting that the regional retail market is
sufficiently serving the local population.
Truck transportation, warehousing and distribution and several other transportation-related categories
have noticeably low location quotients in Milwaukee’s Industrial Corridor, but higher LQs in the M7 Region
(note that several of these categories are not listed as a top 50 industry in either Table 2.4 or Table 2.5).
While these distributions may reflect several site preference factors, the low LQs in the Industrial Corridor
are somewhat surprising as manufacturing and wholesale are primary demand sources for these
transportation industries. Furthermore, the Industrial Corridor includes the Port of Milwaukee, Mitchell
International Airport, considerable railroad connections and a significant Interstate highway presence that
provide key infrastructure for transportation-related industries;
Also absent from Table 2.4 are construction (LQ = 0.59) and professional, technical and scientific services
(LQ = 0.54). While these industries have low location quotients in the Industrial Corridor, they also show
low LQs in the broader M7 counties as well. These figures could suggest either a potential service gap or
insufficient regional demand for these services.

Industry Employment Trends
While past trends in employment do not necessarily dictate an industry’s future trajectory, examining local
employment change relative to an industry’s national peers provides some perspective to whether an industry
might present a strength, weakness, opportunity or threat for a given region. One common method for
exploring industry employment trends is quadrant analysis (Figure 2.2). Quadrant analysis places regional
industries into one of four categories based on employment change between the current year and some prior
year:3
Quadrant 1: Specialized industries with an increasing share of national industry employment – Industries in
this quadrant have a current location quotient above 1.0 and a location quotient that has increased
between the current year and a prior year. These industries are specialized in a region and are growing in
their relative share of the industry’s national employment. Note that industries in this quadrant can have
a growing share of national employment despite declining local employment when a local industry is
contracting at a slower rate than the overall national average for the industry;
Quadrant 2: Specialized industries with a decreasing share of national industry employment – Industries in
Quadrant 2 have a location quotient greater than one, but also have a location quotient that has declined
over time. That is, local establishments are losing their share of the industry’s total national employment.
As with Quadrant 1, an industry’s inclusion in this quadrant depends on local employment change relative
to the national average. A local industry in this quadrant may be growing more slowly than its national
peers or shedding employment at a faster rate than the national average. Consequently, local industries in
this quadrant may be either growing or declining in employment;
Quadrant 3: Non-specialized industries
with an increasing share of national
industry employment – Industries in
this quadrant have a location quotient
below 1.0, and a location quotient that
has increased over time. These non-
specialized industries are growing in
their relative share of national
employment and are sometimes
characterized as potential emerging
industries;
Quadrant 4: Non-specialized industry
with a decreasing share of national
industry employment – Industries in
Quadrant 4 have a location quotient
below 1.0, and a location quotient that
has decreased over time.
3 Similar schemes have been used by Michael Porter of Harvard University’s Institute for Strategy and Competitiveness and other
researchers when categorizing industry changes.

Transform Milwaukee 2-14 Industry Structure Analysis
Using these quadrants, changes in local industries are measured between 2005 and 2010. As time series
employment figures are unavailable for the Industrial Corridor, the quadrant analysis instead relies on
employment in Milwaukee County to provide local industry insight. The two years of 2005 and 2010 are
selected as they reflect the period before and after the recession that officially spanned December 2007 to
June 2009. Again, 2010 does not reflect more recent changes in employment, but 2005 can be considered a
somewhat “normal” year in terms of national economic cycles. In addition to using a different geographic
unit, the employment figures used in the quadrant analysis are derived from the QCEW program rather than
IMPLAN. Subsequently, the employment estimates in the following tables will differ from the figures
previously reported in Section 2. Also note that a local industry’s change in employment compared to the
national rate does not necessarily provide insight into a local industry’s competitiveness relative to its national
peers.
Industries in Quadrant 1 (Location Quotients Greater than 1.0 and Increasing National Shares of
Employment) – Based on employment changes between 2005 and 2010, fourteen Milwaukee County
industries are found in Quadrant 1 (Table 2.6). Of those industries in Quadrant 1, only six actually
increased their employment over this period. Social assistance, private households, and management of
companies and enterprises added the greatest number of employees, with employment increases in social
assistance and private households likely driven by the recession. While the four manufacturing categories
in this quadrant experienced employment losses (NAICS 335, 333, 323 and 332), their declines occurred at
slower rates than the national averages for their respective sub-sectors. Accordingly, these four
manufacturing categories captured a greater share of the nation’s total employment over this period.

Industries in Quadrant 2 (Location Quotients Greater than 1.0 and Decreasing National Shares of
Employment) – The industries in Quadrant 2 are a mix of sectors (Table 2.7). Six industries are
manufacturing sub-sectors, each showing varying changes in employment. For instance, the food
manufacturing industry experienced minimal losses in terms of its employment and location quotient,
while primary metal manufacturing employment declined by almost 50 percent during the brief period
between 2005 and 2010. Ambulatory health care services and transit and ground passenger transportation
added a small number of jobs over this period. However, these additions were at lesser rates than the
national average, accounting for Milwaukee County’s decreasing share of total national employment in
these two industries. Reflecting layoffs at Midwest Airlines and Skyway Airlines in 2008 and 2009, air
transportation showed the greatest employment losses in Quadrant 2.

Industries in Quadrant 3 (Location Quotients below 1.0 and Increasing National Shares of Employment) –
As with the previous quadrants, industries in Quadrant 3 are largely mixed among sectors and also vary in
employment changes between 2005 and 2010 (Table 2.8). Educational services and utilities accounted for
the two largest overall employee gains, with the location quotient for utilities increasing notably from 0.54
to 0.98. Note that employment figures for educational services (NAICS 611) in Table 2.8 differ significantly
from previously reported values due to the aforementioned considerations. Despite heavy declines in the
overall manufacturing sector, several manufacturing categories in Table 2.8 also added jobs in Milwaukee
County, including the non-durable categories of plastics and rubber products; paper; and wood products.
Job losses for the remaining manufacturing categories in Quadrant 3 were minimal.
Transform Milwaukee 2-16 Industry Structure Analysis
Many of the industries found in Quadrant 3 also were previously noted for their low location quotients in
the Industrial Corridor (Table 2.4), including several construction, retail and transportation-related
categories. Nonetheless, several of these industries not only increased their share of national
employment, but also grew in local employment between 2005 and 2010. Specifically, heavy and civil
engineering construction added more than 1,000 jobs during this period, while support activities for
transportation added 100 jobs and warehousing and storage added almost 500 jobs. As heavy and civil
engineering construction includes road construction, the Marquette Interchange reconstruction and other
significant highway projects in Milwaukee County during this period likely contributed to this category’s
employment increase.

Industries in Quadrant 4 (Location Quotients below 1.0 and Decreasing National Shares of Employment)
Several notable industries in Quadrant 4 (Table 2.9) are professional and technical services; truck
transportation; and a variety of retail categories including sporting goods, hobby, book and music stores;
furniture and home furnishings stores; food and beverage stores; motor vehicle and parts dealers; non-
store retailers; general merchandise stores; and clothing and clothing accessories stores. These industries
are particularly relevant as they were mentioned previously as potential gaps in the Milwaukee Industrial
Corridor.
Of the four manufacturing categories found in Quadrant 4, the largest employment losses were sustained
by transportation equipment manufacturing and chemical manufacturing. Large employment declines in
other sectors are found in merchant wholesale of non-durable goods and within publishing industries.
Public administration is also found in Quadrant 4, but the figures in Table 2.9 are not comparable to
previously reported government employment figures. Specifically, the nearly 22,000 employees included
in Table 2.9 do not include employment from educational services, health care and other industry sectors
showing some levels of public-sector employment.

Total Industrial Output
Total industrial output (TIO) is a basic measure of economic activity that examines an industry’s total value of
production within a region. For the IMPLAN data used here, TIO is an industry’s annual production estimate
for 2010 and is reported in producer prices. TIO for manufacturers is sales plus/minus changes in inventory.
Output for service sectors is equivalent to sales, while TIO for retail and wholesale trade is gross margin and
not gross sales.
To understand local production levels, the top 50 industries in the Milwaukee Industrial Corridor are ranked
according to their respective shares of the Corridor’s total TIO for all industries (Table 2.10).4 Levels of total
industrial output per employee are also compared for the Industrial Corridor, the M7 region and the United
States. Examining TIO per employee provides a basic, single factor measure of productivity and informs the
labor requirements for a given industry. However, some caution should be used in interpreting the values in
Table 2.10. As 2010 was an atypical year for many industries, some industries may account for different shares
of output than reported in other years. Furthermore, TIO per employee is not a comprehensive view of
productivity as it does not consider the influence of changes in inputs, technology, organizational efficiency,
capital, economies of scale and other factors. Finally, some differences in TIO per employee among different
areas may arise from the estimation procedures used by IMPLAN rather than true factor conditions.
Industries showing high overall shares of TIO in the Milwaukee Industrial Corridor are not necessarily
highly productive in terms of output per employee. Many population-driven industries with low value
added components account for large shares of total output in the Corridor, but small levels of output per
employee (e.g. health care, accommodations, private educational services, and food services and drinking
places). As these industries are important to local quality of life, it is important to not solely judge the
value of an industry by its relative productivity;
Not surprisingly, large overall shares of TIO are attributed to a number of manufacturing sub-sectors
including the production of chemicals, food products, computer and electronic components, beverages
and fabricated metal products. These industries also are among the most productive in the Corridor when
measured by TIO per employee. The high TIO per employee in chemical manufacturing also shows that an
industry does not necessarily need to be large employer to be productive, as this industry accounted for
fewer employees than many other industries ranked in Table 2.10;
While manufacturing tends to have high relative levels of output per employee, manufacturing sub-sectors
in the Corridor often suggest lower levels of TIO per employee than their peers in the M7 Region and the
United States. Of the fourteen manufacturing sub-sectors ranked in Table 2.10, only leather and allied
product manufacturing and furniture and related product manufacturing have greater levels of TIO per
employee in the Corridor than their respective industry national averages. Consequently, the remaining
manufacturing industries in the Industrial Corridor appear to be somewhat less productive when
compared to their national counterparts. A variety of factors could explain these differences (different
product mix, lower efficiency, etc.), but caution should be used in drawing too many conclusions given the
aforementioned caveats on using TIO per employee as a measure of productivity. Whatever the reasons,
these numbers may point to opportunities for increasing the productivity of local firms.
4 Total TIO for the Corridor in 2010 was an estimated $22.5 Billion

Potential Gaps and Disconnects
Location quotients provide some insight into the import or export of goods and services within an area. Given
the previous discussion of location quotients, it is natural to assume than an industry with a large LQ and high
levels of employment should be exporting a large share of products. However, an industry showing a small
location quotient and limited employment does not necessarily mean that that the local economy is importing
the industry’s goods or services at a high level. Instead, a small location quotient for a given industry may
simply mean that there is little local demand for the industry’s goods or services. To better understand the
flow of goods and services to and from the regional economy, the following analysis considers estimated
imports in the M7 Region. More specifically, imports are evaluated in the context of potential “gaps” and
“disconnects” in the regional economy.
High import levels of a good or service into the M7 Region can be attributed to one of several reasons. First, a
given good or service can be imported into the regional economy because it is simply not produced or
available locally. In this instance, the unavailable good or service is a gap in the economy. A local example of
a gap is coal. Coal is used by a number of regional industries and must be imported as there are no coal mines
in the M7 Region. There are many reasons for gaps rooted in classic industrial location theory where certain
goods can only be efficiently produced in specific locations. Furthermore, certain gaps actually can be
desirable in industries that could pose a negative impact on the regional economy or local quality of life;
In other instances, goods or services may be imported into the region even though the good or service could
be available in the local economy. However, despite its potential availability, businesses or consumers choose
to purchase the good or service outside of the region. In this case, the imported good or service can be
considered a “disconnect” between supply and demand. Reasons for a disconnect include a lack of
information within the business community, long standing supply chain partnerships between firms,
unfavorable pricing policies, mistrust, or specialization or expertise of firms in a specific industry.
When goods and services must be purchased outside of the region, these imports can be viewed as a “leakage”
of economic activity from the region. Consequently, evaluating gaps and disconnects may suggest
opportunities for reducing imports within certain categories through “import substitution.” That is, there may
be opportunities to replace some level of imports by substituting goods and services produced by regional
companies. These import substitution opportunities could ultimately suggest prospects for strengthening
current businesses in Milwaukee’s Industrial Corridor or spurring new business development.
To help identify possible gaps and disconnects in the M7 Region, estimates of the largest imported goods and
services were developed using an IMPLAN input-output model created for the region (Table 2.11). Imports are
also compared to estimated production levels for the same commodities in the M7 Region. Reporting imports
alongside current production levels provides some perspective on whether the imported product is due to a
gap or disconnect. If there is no commodity production in the region, then the imported commodity must
constitute a gap. In contrast, if some production exists in the region, there is a possibility the import is
attributed to a disconnect. Note that only so-called intermediate imports are included in Table 2.11.
Intermediate imports are goods or services imported into the region by private industries, rather than those
imported by public institutions (e.g. schools) or households. 5
5 While goods and services also may be imported by public institutions or private households, imports by industries are of the greatest
concern for supply chain considerations.
Transform Milwaukee 2-21 Industry Structure Analysis
As the import figures are based on national purchasing patterns among industry sectors, these estimates
should be used only to spark discussion and guide targeted research efforts. If import substitution is pursued
as an economic development strategy, opportunities will need to be confirmed with local primary research,
such as a business owner survey or other interview methods. Consequently, businesses are cautioned not to
rely on the figures in Table 2.11 to make operational decisions. Nonetheless, a number of observations are
apparent when considering the intermediate import figures for the M7 Region:
Iron, steel and ferroalloy products are the largest imported good, accounting for more than $1.3 billion in
value. The largest importers of iron, steel and ferroalloy products are the region’s transportation
equipment manufacturing, machinery manufacturing and fabricated metal products manufacturing
industries. The M7 Region also produced more than $368 million in iron, steel and ferroalloy products,
suggesting that there is an existing presence of production. While good reasons likely explain the high
levels of imports, the disconnect between imported goods and the potential availability of local producers
provides an opportunity for further research into local supply and demand;
A variety of other metal products and commodities are imported at notable levels including machined
products; aluminum products; rolled, drawn, extruded and alloyed copper; coated engraved and heat
treated products; ornamental and architectural metal products; turned products and screws, nuts, and
bolts; rolled, drawn, extruded, and alloyed non-ferrous metals, plates and fabricated structural products;
and metal cans, boxes and other metal containers. With the exception of aluminum and copper products,
industries producing these products are available at a sizeable level in the M7 Region. Again, reasons for
the importation of these products likely exist, but these product categories provide additional
opportunities for exploring import substitution;
Refined petroleum products and plastics materials and resins also show import values in excess of $1
billion. Notable importers of refined petroleum products include chemical manufacturing, construction
and machinery manufacturing. Not surprisingly, the Region’s plastic manufacturing industry is a primary
importer of plastics materials and resins. Some regional production within these two product categories
exists, but refined petroleum products and plastics materials and resins are not likely candidates for import
substitution due to the transportation costs associated with the inputs used by these industries.
A variety of plastics products are imported into the M7 Region. Likely importers of plastic products include
sanitary paper products manufacturing; food manufacturing; hospitals and ambulatory health care
facilities; medical equipment manufacturing; construction; and machinery manufacturing. Despite a
notable presence of plastics manufacturers in the region, the levels of imports are not surprising as the
types of plastics products needed by local industries are diverse and specialized in many instances.
Nonetheless, there may be opportunities for exploring import substitution for plastic products.
Cattle from ranches and farms; petrochemicals; and animal products (except cattle poultry and eggs),
show sizeable import levels, but with relatively little production in the M7 Region. However, these
categories provide little import substitution opportunity for firms in Milwaukee’s Industrial Corridor;
Several categories of professional and technical services show large relative import levels including
scientific research and development services; management, scientific and technical consulting services and
other miscellaneous professional, scientific and technical consulting services. While there are firms
providing these services in the M7 Region, the import levels are not surprising given these industries’
aforementioned low location quotients.

Transform Milwaukee 2-23 Industry Structure Analysis
Regional Analysis of Establishment Concentration
Industrial agglomeration is a concept that can be traced back over a century and remains an important
component in the analysis of industrial location. Agglomeration economies are associated with the
competitiveness and cost savings resulting from a business’ proximity to markets, suppliers and labor force.
More specifically, a concentration of firms in a given industry can influence production costs through the
presence of suppliers competing for business, a greater specialization of supporting firms, and the
development of a specialized labor force. Furthermore, the greater the number of similar firms located in an
area, the greater the overall market to which businesses can sell goods and services.
Recent trends in globalization associated with higher adoption rates of technology, easier communication,
international wage rates, and lower transportation and communication costs certainly have undercut many
advantages formerly inherent in agglomeration economies. However, the presence of agglomeration
economies and the somewhat related concept of industry clusters remain important considerations for
understanding a region’s potential specialization and competitive advantage in national and international
contexts.
A variety of methods are available for evaluating industry agglomeration and geographic clustering. As this
analysis is not intended to be a formal industry cluster evaluation, the following overview of regional
agglomeration relies on a basic spatial analysis technique known as neighborhood analysis. Neighborhood
analysis evaluates the characteristics of an area surrounding a specific location. In this instance, the
neighborhood analysis examines the number of establishments in various industry categories within a 100-mile
radius around Milwaukee County. A 100-mile radius is used as this distance often defines the service area for
short-haul trucking operations that could quickly connect customers and suppliers within supply chains.
Knowing the number of an industry’s establishments within this radius provides several insights to the regional
economy:
Industries with high concentrations of establishments within a 100-mile radius may suggest a regional
specialization that could differentiate Milwaukee’s economy from other metropolitan areas;
Understanding the number of a given industry’s establishments within 100 miles may point to a market for
those firms that are potential suppliers or customers of the industry;
Numbers of establishments within 100-miles of Milwaukee are also reported as a share of all national
establishments within a given industry. To provide some context as to what value might constitute a high or
low national share of establishments for a given industry, Milwaukee County contained 0.31% of the United
States population in 2010, while the region within a 100-mile radius encompassed 4.24% of the nation’s
population. These population shares can be viewed as rudimentary thresholds. For instance, if an industry
has more than 4.24% of its establishments within a 100-mile radius of Milwaukee, then the industry could have
a disproportionate concentration in the region. However, these values should only be used as basic guidelines
as there are a variety of conditions where using a population threshold fails to describe local market
conditions. Specifically, the neighborhood analysis of establishments says nothing about the relative size of
these establishments in terms of production capacity, employment or revenues.
Transform Milwaukee 2-24 Industry Structure Analysis
In addition to calculating the number of establishments within 100 miles of Milwaukee County, figures are also
calculated for every county in the United States. While it is not feasible to include all calculations in this study,
figures are available on a county-by-county basis or depicted on maps upon request (Map 2.1 provides a
sample and shows the national distribution of establishments in NAICS 3335). The maps and county-by-
county calculations can be used to identify regions that potentially compete with Milwaukee within a given
industry category. Identifying competing regions allows for targeted competitive intelligence to be gathered
and may point to areas with a large number of potential candidates available for industry recruitment.
The national shares of establishments within a 100-mile radius of Milwaukee County are ranked using both
three-digit NAICS industry classifications (Table 2.12) and four-digit NAICS categories (Table 2.13). The number
and national share of establishments in Milwaukee County are also reported for comparison purposes. Note
that counties in Michigan’s Lower Peninsula within a 100-mile straight line distance of Milwaukee County are
excluded from the calculations. Relevant conclusions from these figures are:
Despite the declines in manufacturing over the past decades, establishment data show the continuing
prominence of the Milwaukee-Green Bay-Chicago corridor as a dominant manufacturing center in the
United States. Eleven of the top 13 industries in Table 2.12, and 20 of the top 25 listings in Table 2.13, are
found in the manufacturing sector;
Highly-ranked manufacturing industries aggregated at the three-digit NAICS level (Table 2.12) are a mix of
durable and non-durable products. However, the top categories at the four-digit NAICS level (Table 2.13)
are mostly in durable manufacturing categories related to fabricated metal products and machinery.
Other durable manufacturing categories highly ranked in Table 2.13 include those related to primary metal
products, computer and electronic components and transportation equipment;
While not as prevalent as durable products, several non-durable manufacturing categories appear to have
a high national share of establishments both within a 100-mile radius and in Milwaukee County. These
categories include manufacturing of paper, leather and allied products, plastics and rubber products,
chemicals, printing and food;
Several of the ranked industries are driven largely by establishments in counties surrounding Milwaukee
County, rather than Milwaukee itself. Securities and commodity exchanges; dairy product manufacturing;
pulp and paperboard mills; spring and wire manufacturing; hardware manufacturing; and cutlery and hand
tool manufacturing show little to no establishments in the county, but are highly ranked in the 100-mile
region;
While the region’s concentration of dairy product manufacturing is driven by outlying areas, other food
product manufacturing categories are concentrated in both Milwaukee County and the broader 100-mile
region. These categories include manufacturing of sugar and confectionery products, other food products,
baking products and tortillas and, to a lesser degree, fruit and vegetable preserving and specialty foods.
While not shown in Table 2.13, animal slaughtering and processing also has a high national share of
establishments in Milwaukee County and within a 100-mile radius;
The large national share of professional, scientific and technical service establishments within a 100-mile
radius is likely driven by a large concentration of firms within the Chicago metropolitan area. The large
Transform Milwaukee 2-25 Industry Structure Analysis
presence of this industry in the Chicago area may partially explain this industry’s aforementioned low
location quotients in both the Industrial Corridor and the broader M7 Region. That is, Chicago may be
capturing some of the local demand for professional, scientific and technical services.
As suggested with other measures of industry scale in Section 2, truck transportation appears to be
underrepresented in Milwaukee County and more highly concentrated in the broader 100-mile region.
Warehousing and storage also has a potentially smaller share of establishments in both the 100-mile
region and Milwaukee County when compared to the populations of these areas. However, several other
transportation and logistics related industries, such as other support activities for transportation (NAICS
4889) and freight transportation arrangement (NAICS 4885), appear to have above average shares of
establishments in the region;
The construction sector continues to suggest relative weakness in Milwaukee County compared to the
concentration of firms within a 100-mile radius. Specifically, both construction of buildings (NAICS 236)
and specialty trade contractors (NAICS 238) appear to have a national share of establishments below
Milwaukee County’s population threshold and above the threshold in the 100-mile radius region. Greater
detail on the construction industry is provided in Section 9.

Transform Milwaukee 2-28 Industry Structure Analysis
Conclusions
As noted in the introduction to this section, a primary goal of the industry structure analysis is to identify
industries that could guide recruitment, expansion and retention activities in Milwaukee’s Industrial Corridor.
Based on the preceding discussion, a number of industries are listed below that could provide a foundation for
these efforts. The identification of these industries was based on several important criteria including the
presence of regional concentrations, specializations, high levels of average compensation, potential to fill gaps
in the local economy or relative resiliency in the recent recession.
As noted earlier, the industry structure analysis is a broad assessment of opportunities. Inclusion of these
industries does not imply that they will necessarily succeed in the Industrial Corridor, but rather that they
deserve further analysis in this study or as a consideration in future development initiatives. While detailed
evaluations of every potential target industry are beyond the scope of this study, several in-depth analyses are
included in Section 6, Section 7, Section 8 and Section 9 of this report. The industry overviews in these three
sections provide a potential template for exploring additional industries and include information regarding
industry trends, supply chains, competition, workforce considerations, projected revenues, and site selection
criteria.
Manufacturing
Manufacturing employment in Milwaukee County has declined by almost 66% over the past three decades.
This level of deindustrialization may suggest that manufacturing should receive little consideration as an
opportunity for retention, expansion and recruitment efforts. While efforts are needed to diversify the
community’s (and region’s) industrial base, a number of manufacturing sub-sectors still should be considered
including: primary and fabricated metal products; machinery; electrical equipment, appliance and
components; food products; and plastics. Other secondary categories could include transportation equipment
manufacturing, printing, medical devices; and computer and electronic components. These categories are
considered based on the following rationale:
These manufacturing categories remain highly concentrated in the Milwaukee Industrial Corridor, the M7
Region and Lake Michigan Corridor, providing potential agglomeration economies and sources of
economic specialization;
With a few exceptions, these manufacturing sub-sectors provide relatively high average compensations,
are highly productive, and proved to be largely more resilient than their national peers during the recent
recession;
As will be noted in Section 3, these manufacturing sub- sectors currently align or have the potential to
align with the broader skills base of the local labor force. These sub-sectors are also increasing in rates of
technology development and adoption, providing opportunities to re-invent their competitiveness in the
region, as well as combine the area’s research, design and production strengths;
Transform Milwaukee 2-29 Industry Structure Analysis
Land use in the Milwaukee Industrial Corridor remains appropriate for manufacturing. While
infrastructure and physical characteristics of sites in the Corridor vary, the Menomonee Valley also shows
how a well-planned manufacturing park can spur new development in an urban setting;
These manufacturing industries provide opportunities to connecting to the regional, national and
international economies. Furthermore, additional research could suggest opportunities for import
substitution in a variety of categories (e.g. metals, plastics, electrical equipment and electronics
components);
While on-shoring of industrial activity is gaining attention, the overall effect and magnitude of overseas
manufacturing returning to the United States is not yet fully understood. Accordingly, this phenomenon is
recognized, but is not necessarily a rationale for aligning manufacturing with retention, expansion and
attraction efforts.
Finally, these manufacturing industries are somewhat aligned with other economic development initiatives
in the area. Many of aforementioned sub-sectors are also industries targeted by M7 and the 30th Street
Industrial Corridor Plan produced for the City of Milwaukee. A number of these manufacturing sectors
also align with efforts to develop the region’s water cluster. Specifically, many of the aforementioned
manufacturing sub-sectors are water-intensive industries in terms of water use in their manufacturing
processes. Other sub-sectors produce products that incorporate technology developed by research and
development efforts in the water cluster.
Freight Transportation, Warehousing and Logistics
Despite the presence of the Port of Milwaukee, General Mitchell International Airport and a highly connected
rail and Interstate highway system, industries related to freight transportation, warehousing and logistics
appear to be mostly underrepresented in Milwaukee’s Industrial Corridor (and the M7 Region in some
instances). As these industries are potentially aligned with the Corridor’s infrastructure, deliver important
services to local manufacturing industries, and provide potential linkages to external economies, the freight
transportation industry is further examined in Section 8 of this report. Specific considerations include the
market for single and multi-modal freight transportation; freight arrangement and logistics services; and
warehousing and distribution.
Construction
Similar to the freight transportation-related industries, the construction sector suggests lower concentrations
in Milwaukee’s Industrial Corridor and M7 Region. Note that the construction industry levels in the region may
not necessarily represent a gap in supply for construction services. Furthermore, construction may not provide
the deep or immediate external economic connections needed by the central city. However, understanding
the potential for construction-related industries is necessary to supporting site assembly and redevelopment
needs within the Milwaukee Industrial Corridor. The construction industry also is particularly relevant to the
Transform Milwaukee 2-30 Industry Structure Analysis
entrepreneurship discussion presented in Section 4 of this report. Accordingly, Section 9 explores sub-sectors
of the industry including: construction of buildings; heavy and civil engineering construction; and specialty
trade contractors.
Other Opportunities
In addition to the aforementioned industries, several other sectors show either possible gaps or strengths in
the Industrial Corridor. Industries showing prospective gaps include professional, technical, and scientific
services and most retail categories, while health care is a potential strength. These industries are not selected
specifically for further analysis given the goals of this study, but should be considered as opportunities for
future development and diversification efforts.

Appendix 2A – Basics of Input-Output Modeling
A simple non-technical discussion of the formulation of input-output (IO) modeling is presented in this
appendix. This was written by Professor Steve Deller of UW-Madison’s Department of Agricultural and Applied
Economics. Similar descriptive treatments are readily available, including Shaffer, Deller and Marcouiller
(2004), while more advanced discussions of input-output include Miernyk (1965), and Miller and Blair (1985).
As a descriptive tool, IO analysis represents a method for expressing the economy as a series of accounting
transactions within and between the producing and consuming sectors. As an analytical tool, IO analysis
expresses the economy as an interaction between the supply and demand for commodities. Given these
interpretations, the IO model may be used to assess the impacts of alternative scenarios on the region's

A central concept of IO modeling is the interrelationship between the producing sectors of the region (e.g.,
manufacturing firms), the consuming sectors (e.g., households) and the rest of the world (i.e., regional imports
and exports)6. The simplest way to express this interaction is a regional transactions table (Table A1). The
transactions table shows the flows of all goods and services produced (or purchased) by sectors in the region.
The key to understanding this table is realizing that one firm's purchases are another firm's sales and that
producing more of one output requires the production or purchase of more of the inputs needed to produce
that product.
The transactions table may be read from two perspectives. Reading down a column gives the purchases by the
sector named at the top of the column from each of the sectors named at the left. Reading across a row gives
the sales of the sector named at the left of the row to those named at the top.
In the illustrative transaction table for a fictitious regional economy (Table A1), reading down the first column
shows that the agricultural firms buy $10 worth of their inputs from other agricultural firms. The sector also
buys $4 worth of inputs from manufacturing firms and $6 worth from the service industry. Note that
agricultural firms also made purchases from non-processing sectors of the economy, such as the household
sector ($16) and imports from other regions ($14)7. Purchases from the household sector represent value
added, or income to people in the form of wages and investment returns. In this example, agricultural firms
purchased a total of $50 worth of inputs.
Reading across the first row shows that agriculture sold $10 worth of its output to agriculture, $6 worth to
manufacturing, and $2 worth to the service sector. The remaining $32 worth of agricultural output was sold to
households or exported out of the region. In this case, $20 worth of agricultural output was sold to
households within the region and the remaining $12 was sold to firms or households outside the region. In the

as small as a specific county.

terminology of IO modeling, $18 (=$10+$6+$2) worth of agricultural output was sold for intermediate
consumption, and the remaining $32 (=$20+$12) worth was sold to final demand. Note that the transactions
table is balanced: total agricultural output (the sum of the row) is exactly equal to agricultural purchases (the
sum of the column). In an economic sense, total outlays (column sum, $50) equal total income (row sum, $50),
or supply exactly equals supply. This is true for each sector.

The transactions table is important because it provides a comprehensive picture of the region's economy. Not
only does it show the total output of each sector, but it also shows the interdependencies between sectors. It
also indicates the sectors from which the region's residents earn income as well as the degree of openness of
the region through imports and exports. In this example households' total income, or value added for the
region is $132 (note total household income equals total household expenditure), and total regional imports is
$88 (note regional imports equals regional exports). More open economies will have a larger percentage of
total expenditures devoted to imports. As discussed below, the “openness” of the economy has a direct and
important impact on the size of economic multipliers. Specifically, more open economies have a greater share
of purchases, both intermediate and final consumption purchases, taking the form of imports. As new dollars
are introduced (injected from exports) into the economy, they leave the economy more rapidly through
leakages (imports).
Direct Requirements Table
Important production relationships in the regional economy can be further examined if the patterns of
expenditures made by a sector are stated in terms of proportions. Specifically, the proportions of all inputs
needed to produce one dollar of output in a given sector can be used to identify linear production
relationships. This is accomplished by dividing the dollar value of inputs purchased from each sector by total
expenditures. Or, each transaction in a column is divided by the column sum. The resulting table is called
the direct requirements table (Table A2).
The direct requirements table, as opposed to the transactions table, can only be read down each column. Each
cell represents the dollar amount of inputs required from the industry named at the left to produce one
dollar's worth of output from the sector named at the top. Each column essentially represents a `production
recipe' for a dollar's worth of output. Given this latter interpretation, the upper part of the table (above
households) is often referred to as the matrix of technical coefficients. In this example, for every dollar of sales
by the agricultural sector, 20 cents worth of additional output from itself, 8 cents of output from
manufacturing, 12 cents of output from services, and 32 cents from households will be required.

In the example region, an additional dollar of output by the agricultural sector requires firms in agriculture to
purchase a total of 40 cents from other firms located in the region. If a product or service required in the
production process is not available from within the region, the product must be imported. In the agricultural
sector, 28 cents worth of inputs are imported for each dollar of output. It is important to note that in IO
analysis, this production formula, or technology (the column of direct requirement coefficients), is assumed to
be constant and the same for all establishments within a sector regardless of input prices or production levels.
Assuming the direct requirements table also represents spending patterns necessary for additional
production, the effects of a change in final demand of the output on the other of sectors can be predicted.
For example, assume that export demand for the region's agricultural products increases by $100,000. From
Table A2, it can be seen that any new final demand for agriculture will require purchases from the other
sectors in the economy. The amounts shown in the first column are multiplied by the change in final demand
to give the following figures: $20,000 from agriculture, $8,000 from manufacturing, and $12,000 from
services. These are called the direct effects and, in this example, they amount to a total impact on the
economy of $140,000 (the initial change [$100,000] plus the total direct effects [$40,000]). For many studies
of economic impact, the direct and initial effects are treated as the same although there are subtle
differences.
The strength of input-output modeling is that it does not stop at this point, but also measures the indirect
effects of an increase in agricultural exports. In this example, the agricultural sector increased purchases of
manufactured goods by $8,000. To supply agriculture's new need for manufacturing products, the
manufacturing sector must increase production. To accomplish this, manufacturing firms must purchase
additional inputs from the other regional sectors.
Continuing our $100,000 increase in export demand for a region’s agricultural products, for every dollar
increase in output, manufacturing must purchase an additional 12 cents of agricultural goods ($8,000 x .12 =
$960), 8 cents from itself ($8,000 x .08 = $640), and 4 cents from the service sector ($8,000 x .04 = $320).
Thus, the impact on the economy from an increase in agricultural exports will be more than the $140,000
identified previously. The total impact will be $140,000 plus the indirect effect on manufacturing totaling
$1,920 ($960 + $640 + $320), or $141,920. A similar process examining the service sector increases the total
impact yet again by $1,440 ([$12,000 x .04] + [$12,000 x .06] + [$12,000 x .02] = $1,440).
The cycle does not stop, however, after only two rounds of impacts. To supply the manufacturing sectors with
the newly required inputs, agriculture must increase output again, leading to an increase in manufacturing and

service sector outputs. This process continues until the additional increases drop to an insignificant amount.
The total impact on the regional economy, then, is the sum of a series of direct and indirect impacts.
Fortunately, the sum of these direct and indirect effects can be more efficiently calculated by mathematical
methods. The methodology was developed by the Noble-winning economist Wassily Leontief and is easily
accomplished in computerized models.
Total Requirements Table
Typically, the result of the direct and indirect effects is presented as a total requirements table, or the Leontief
inverse table (Table A3). Each cell in Table A3 indicates the dollar value of output from the sector named at
the left that will be required in total (i.e., direct plus indirect) for a one dollar increase in final demand for the
output from the sector named at the top of the column. For example, the element in the first row of the first
column indicates the total dollar increase in output of agricultural production that results from a $1 increase
in final demand for agricultural products is $1.28. Here the agricultural multiplier is 1.28: for every dollar of
direct agricultural sales, there will be an additional 28 cents of economic activity as measured by industry
sales.
An additional, useful interpretation of the transactions table, as well as the direct requirements and total
requirements tables, is the measure of economic linkages within the economy. For example, the element in
the second row of the first column indicates the total increase in manufacturing output due to a dollar
increase in the demand for agricultural products is 12 cents. This allows the analyst to not only estimate the
total economic impact but also provide insights into which sectors will be impacted and to what level.
Highly linked regional economies tend to be more self-sufficient in production and rely less on outside sources
for inputs. More open economies, however, are often faced with the requirement of importing production
inputs into the region. The degree of openness can be obtained from the direct requirements table (Table A2)
by reading across the imports row8. The higher these proportions are the more open the economy. By
definition, as imports increase the values of the direct requirement coefficients will decline. It follows then
that the values making up the total requirements table, or the multipliers, will be smaller. In other words,
more open economies have smaller multipliers due to larger imports. The degree of linkage can be obtained
by analyzing the values of the off-diagonal elements (those elements in the table with a value of less than
one) in the total requirements table. Generally, larger values indicate a tightly linked economy, whereas
smaller values indicate a looser or more open economy.

8As described above, the openness of the economy can also be discussed in terms of leakages; greater leakages translate into a
more open economy.
