A. Objectives
• This Learning Tool was prepared for professionals with some training in economics. It will provide professionals with some of the basic analytical tools they need in their work in analyzing taxation and in working on teams to reform tax systems. Understanding and applying these analytic tools will help deepen the analyst’s understanding of the economic and social issues related to taxation and will take the analyst beyond merely being able to parrot the advice of top professionals in the field.

B.6 Conclusions
B.1 Criteria for Evaluating Taxes
• Efficiency• Simplicity• Equitable treatment
More criteria: two faces of the same coin
• Concentration
• Erosion
More criteria
• Objectivity
• Compliance
• Administrative costs

Income tax and savings
• Income tax differs from consumption tax
• Consumption tax usually on transactions
• Income tax on accounts
• Tax base is equal to consumption plus saving
• So, does income tax affect saving?
B.5 Tax incidence
• Who really bears the burden of a tax
• It is measured in terms of lost surplus
• How taxes are really shared, depends on supply and
demand elasticities
Tax incidence: excise unit tax

Incidence: VAT
• Full incidence is on the consumer• Since poor people consume all of their income but
the rich only a portion, then it must be true that the tax is regressive?
• Savings is merely future consumption, so maybe not.
Incidence and social class
• First, calculate who bears the incidence in the market– Producer– Consumer– Worker– Employer
• Then see how these persons are distributed by income class• Some questions
B.6 Conclusions
• Tax bases should be as broad as possible• Tax rates should be as low as possible• Income tax may or may not reduce the supply of
labor• Income tax may or may not affect savings• Tax incidence is based on elasticities• Tax cannot be exported
C. Tax Incentives
C.1 Types of tax incentives
C.2 Arguments for and against
C.3 Analytical tools
C.4 Case studies
C.5 Consensus among experts
C.6 Conclusions
C.1 Typology (profit/CIT)
• Low rates/differential rates• Investment tax credits• Tax holidays• Accelerated depreciation• Loss carry forward
C.2 Arguments for and against tax incentives
• For– Increase employment– Compensate for bad infrastructure– Encourage business formation– Attract foreign investment
• Against– Unfair, raise burden on others– Unfair competition, I succeed because of tax break not
because of better product, service, or management.– Open to cheating– Usually do not really work
C.3 Analytical tools
• Cost of capital model
• Favored sector
• Non-favored sector
• Compensated sector
Cost of capital and investing

C.4 Case studies
• Indonesia
• Uganda
• Cape Breton Island in Canada
• What the gurus say
Indonesia 1984
• Company tax reduced from 45% to 35%
• Selective incentives eliminated, such as: tax holidays,
preferential tax rates, and selective investment allowances
• Results
– Number of Foreign Direct Investment projects continued to rise
– Value of Foreign Direct Investments soared after 1986
– Indonesia’s share of Foreign Direct Investments into ASEAN-
Region nearly doubled by early 1990s
This chart adapted from a workshop presentation made By Dr. Bruce Bolnick of Robert Nathan Associates, Inc. at the World Bank, June 2005.
Uganda 1997
• Elimination of new tax holidays in favor of uniform 30% company tax, favorable capital allowances
• Effects: 3-year averages, before and after 1997
1994-1996 1998-2000Gross fixed capital formation, % GDP 15.7 % 16.6 %Foreign direct investment $110 m. $170 m.Tax revenue as % GDP 10.4 % 11.6 %Income tax (non P.A.Y.E), % total tax 9.2 % 9.8 %

Canada: Cape Breton Island
• Investment tax credit up to 60% of the investments
made on Cape Breton Island against Federal Tax
• Objective was to spur growth and create employment
Canada results of evaluation
• Led to substitution of capital for labor
• Lowered costs -> increased profit -> increased production in
Cape Breton
• Cost of jobs created was extremely high
• Cheaper to subsidize labor
• Direct subsidy would have created more jobs
• Only 19 of the investments were incremental
• -> Labor productivity, but->Capital productivity, not sustainable
C.5 What the experts say
• Solidifying positions
• Musgrave and Musgrave 1980
• Dale Chua, IMF: Tax holidays (1995)
• Holland and Van (1998)
• Tanzi and Zee (2000)
C.6 Conclusions
• Tax incentives are attractive to investors who are planning to invest with or
without the tax incentive.
• Tax incentives may lead to increased investment, production and employment,
but this is not necessarily the case.
• Increases in investment and jobs in one sector may decrease investment and
jobs elsewhere, resulting in a net reduction in overall investment and jobs.
• The jobs created because of tax incentives sometimes have been created at
very high cost
• Very careful analysis should be conducted before even contemplating creating
tax incentives.
