Introduction

March 1990: Grain market liberalization in order to get prices right

Agricultural markets remained Thin, Personalised, Seasonal, Cash-based and offering Limited Arbitrage Opportunities

Two main constraints facing traders: High transaction costs and Imperfect market information

Post-structural market reforms focused on getting markets right and getting institutions right

Brokers: informal market institution and informal commodity exchange

Two Main Topics

• Analysis of the main characteristics of Ethiopian agricultural traders Comparison of descriptive statistics from three different surveys

• Investigation of traders’ use of brokers in agricultural markets Decisions: Whether or not to use brokers

For how much (Share of brokered transactions)

Characteristics of Traders

•Grain trading is a male dominated business•Orthodox Christians and Muslims tend to engage more in the business

Page 8: The Brokerage Institution & The Development of Agricultural Markets: New Evidence from Ethiopia

Years in Grain trade, Educational level and Age

• Similar years in grain trade and level of education over the three periods

• Average age is increasing

Page 9: The Brokerage Institution & The Development of Agricultural Markets: New Evidence from Ethiopia

Traders’ parents occupation

• Grain trading business may not be an inherited business

• From time to time, people whose parents are farmers are engaging in the business

Page 10: The Brokerage Institution & The Development of Agricultural Markets: New Evidence from Ethiopia

Assets

• Number of traders who own vehicles is increasing• During 2002 and 2007 almost all of the grain traders had

storage facilities

Page 11: The Brokerage Institution & The Development of Agricultural Markets: New Evidence from Ethiopia

Assets continued…

• Huge increase in Landline telephone/radio ownership

• Drastic change in mobile phone ownership• During 2002 almost all the traders had warehouses but only 29% had

electricity at their warehouse.

Page 12: The Brokerage Institution & The Development of Agricultural Markets: New Evidence from Ethiopia

• Generally, gross margins and net margins have declined noticeably between 1996 and 2007

• The decline is even more amplified by real prices

• Transport costs constitutes the majority of transaction costs• Handling cost and brokers cost are also significant• Other costs , such as payment to daily laborers, tips during sales etc , are large

during 1996 and 2007

Page 14: The Brokerage Institution & The Development of Agricultural Markets: New Evidence from Ethiopia

• Transaction costs in real terms were lower during 2007 as compared to the other two periods.

• Transport cost in real terms has declined by more than 50% between 1996 and 2007

Hypotheses & PremisesTraders in the Ethiopian agricultural markets behave in a rational way,

according to a transaction costs minimization rule

To this aim, tradersa)Implement trading practicesb)Use assets (physical, financial, human and social capital)c)Try to access financial institutions & in/formal credit

The use of brokers (trading practice) &/or of social capital (asset)allows the contextual minimisation of all transaction costs

The use of brokers depends on a), b) & c)

Discrete choice on ‘whether’ to use brokers Continuous decision on ‘how much’ to use brokers for Do not depend on the same set of variables May have marginal effects with different signs

Data & Methodology“ECX Trader Survey 2007” (Gabre-Madhin, EDRI and IFPRI): 457 wholesalers in 21 markets recalled their activity from October/November 2006 to April/May 2007

Page 25: The Brokerage Institution & The Development of Agricultural Markets: New Evidence from Ethiopia

25

Data & Methodology (cont.)

Buyers and sellers are distinguished according to:•Main transacted product:

Food Crops: Cereals, PulsesCash Crops: Coffee, Oilseeds

•Location – Base markets classification: following Chamberlin et al. (2006) classification of smallholder-relevant agricultural domains

Agricultural potential: Moisture-reliable, Drought-prone, Pastoralist Areas, A.A.Market access: Time to towns of 5,000 or more peoplePopulation density

Chamberlin et al. (2006): Food crop commercialization by smallholders Is generally higher in moisture-reliable domains than in the drought-prone domains

Considering specific agricultural domains, it is higherfor Moisture-reliable domains in Areas of lower market accessfor Drought-prone domains in Areas with favourable market access

Increases with population density

Heckman model for Buyers: Regression Results (cont.)

Buyers of cereals based in drought-prone areas:

As distance increases from 7 to 230 kilometres, they are 23.42 percentage points more likely to use brokers than the rest of traders

After the travelled distance reaches and overcomes 160km, all buyers with these characteristics are likely to ask brokers to manage some or all of their long-distant transactions

Heckman model for Buyers: Regression Results (cont.)

As distance increases, the predicted probability of using brokers is more than double when roads are all-weather or dry-weather roads than when they are asphalted roads.

The worst the condition of the road linking the base to the main markets of each buyer, the more it is likely that buyers turn to brokers.

Heckman model for Sellers: Regression Results (cont.)

In 2006/07 production year, the predicted shares of brokered sales were significantly greater by 0.571 units for

sellers of cereals and pulses

based in moisture-reliable domains and

in less accessible and less densely-populated markets

Thus, brokers enhance selling opportunities for sellers based in agricultural domains suitable forfood crop commercialization by farmers

Policy interventions in agricultural markets are likely to have a greater influence on the trading decisions (about whether and for how much to use brokers) of

Those buyers who are currently using brokers

Those sellers that could potentially decide to use brokers after a change in the conditions of their exogenous environment.

Conclusions

The most relevant transaction costs that wholesalers tend to minimise are information and negotiation costs and this is predominantly the case for buyers.

Transaction costs in real terms are declyning from 1996 to 2007.

During the same period, trader assets’ ownership is increasing.

The services of brokers are particularly valuable for:Small-scale trading businesses endowed with limited storage capacity (generally, food

crop traders)Traders with only few years of trading experienceTraders having no access to credit Traders lacking social capital (No. of trading contacts and regular partners).

Brokers support buyers where agricultural potential and crop commercialisation by farmers are low and sellers where these two parameters are high.

Distance impacts on buyers’ decision to use brokers, especially For buyers of cereals based in drought-prone agricultural domainsWhen roads linking base to main markets are all-weather roads.

The availability of a bank in the trader’s main market raises the predicted probability that buyers hire brokerage services.

Policy Implications & Recommendation for Future Research

The findings of this study support the enhancement and formalization of the activities of brokers.

As brokers can facilitate commercialisation across different smallholder-relevant domains, the enhancement of their activities could improve the functioning of Ethiopian agricultural markets.

Further investigation of the role played by brokers in promoting localised market opportunities (for ex. within drought-prone areas), for which the role of smaller urban centres as potential hubs for market development is as relevant as that of major centres a greater distance.

Heckman model for Buyers: Regression Results

Information & Negotiation Costs: The predicted probability that buyers use brokers increases with search labour (human capital) and decreases with the number of trading contacts (social capital); the greater the number of regular suppliers, the smaller the shares of brokered purchases

Brokerage services mainly benefit small-scale trading businesses with limited working capital and storage capacity and with no or limited access to credit

Chamberlin et al. (2006) found that farmers’ commercialization of cereals and pulses is higher in moisture-reliable domains with lower market access and drought-prone domains with good market access. We found that the predicted probability that buyers use brokers is the highest for buyers of cereals based in drought-prone areas and in markets with limited access and low population density

In general, the share of brokered purchases decreases as population density increases, is bigger for traders based in highly-accessible markets and is greater for buyers of cereals and pulses

The presence of a bank (financial institution) in the traders’ main markets increases the predicted probability that they use brokers

Heckman model for Sellers: Regression Results

Sellers seem to be less concerned about the minimization of information costs: the more they can afford to engage manpower in gathering price information (human capital), the less they are likely to use brokers

Shares of brokered sales decrease after an increase in the number of regular customers (social capital)

The relationship between the probability to use brokers and the number of years of operation (human capital) is inverted U-shaped: new trading businesses are more likely to use brokers and this probability decreases as experience is cumulated

Contractual risk: sellers who experience, since the start of the production year, lack of payment from their customers are more likely to use brokers

At the 5 percent significance level, coffee sellers are less likely to use brokers, but their potential/desired shares of brokered sales (for the overall sample of sellers) are positive and exceed in absolute value the shares of other crop traders

Summary Statistics:

The overwhelming majority of traders are male, sole-owners and with an average of 12 years in the trading business

Wholesalers are mostly located in moisture-reliable domains (more than 50 percent), in areas characterised by high market access and high population density (47 percent) and are mainly trading cereals (69.5 percent)

The sample is highly heterogeneous; wholesalers of cereals and pulses (i.e. food crops) have an average working capital four times smaller than that of coffee and oil seed (i.e. cash crops) traders. Moreover, storage facilities exclusively controlled by local cash-crop traders can store, on average, 9 percent more produce than the facilities controlled by food-crop traders

Contractual risk: 30 percent of sellers choose not to sell on credit to avoid the risk of no-payment, while 65 percent of buyers rely on cash-and-carry transactions to reduce monitoring and enforcement costs

93 percent of total purchases and sales are conducted in the traders’ main markets, where the number of trading contacts is the greatest

Summary Statistics (cont.):

Traders’ main markets are well-endowed with electricity, landline and mobile networks.

43 percent of all traders has access to formal and informal credit and, on average, 35 percent of wholesalers are members of trade associations

While main and base markets are distant markets for a larger proportion of buyers than sellers (25 versus 20 percent) , sellers tend to travel on average for longer distances (364km versus 289km for buyers)

Buyers travel a longer distance if roads are asphalted (409km) than if roads are dry- or all-weather roads (172km)

Buyers in drought-prone and pastoralist areas travel on average 157km more than buyers in moisture-reliable areas; sellers in moisture-reliable domains travel on average 97km more than sellers in drought-prone domains

The mean distance covered by cash crop traders (buyers and sellers alike) is 185km greater than the distance covered by food crop wholesalers

Summary Statistics (cont.):

From 1996 to 2006/07, we observe a drop in the number of traders regularly using brokers in their transactions from 85 percent reported by Gabre-Madhin (2001a) down to 68 percent found here

From 1996 to 2006/07, we observe a rise in the predicted shares of total (distant and local) brokered transactions for those traders who are using brokers; these shares have doubled for buyers (from approximately 35.5 to 69.5 percent) and have increased by two-thirds for sellers (from about 31 to 51.1 percent)

Literature ReviewTO POTENTIALLY DELETE

• The crucial role played by brokers in facilitating crop commercialisation in agricultural markets has been widely documented for traders in Sub-Saharan Africa, Latin America, India and China

• Very few studies thoroughly investigated the variables influencing economic agents’ decision to use brokers (Dessalegn et al., 1998; Fafchamps and Gabre-Madhin, 2001; Gabre-Madhin, 2001a; Jabbar et al., 2008)

• Only one study tried to explain and econometrically represent the actual decision process followed by traders and leading to their choice to use brokers (Gabre-Madhin, 2001a)

• Aim: Shine new light on wholesalers’ use of brokers in the Ethiopian grain markets
