Transaction costs and market institutions

This paper examines the effect of transaction costs of search on the institution of grain brokers in Ethiopia. Primary data are used to derive traders' shadow opportunity costs of labor and of capital from IV estimation of net profits. A two-step Tobit model is used in which traders first choose where to trade and then choose whether to use a broker to search on their behalf. The results confirm traders' individual rationality in choosing brokerage, showing high transaction costs are linked to increased broker use while high social capital reduces broker use.Grain Economic aspects. ,Grain Prices Ethiopia. ,Grain Trade East Africa. ,Grain trade. ,

Agricultural markets in Benin and Malawi : the operation and performance of traders

Drawing on original surveys of agricultural traders, the authors examine how traders operate in two Sub-Saharan African countries, Benin and Malawi. They find the following: The largest transaction costs for traders are search and transport. Search methods rely principally on personal visits by the trader, which raises search costs. And since enterprises are very small, transport represents a large share of marketing costs. Brand recognition, grading, and quality certification are nonexistent. Brokers and agents are not organized in commodity exchanges. Quantities are not pooled for transport and storage so as to achieve returns to scale. Interseasonal and interregional arbitrage is not feasible for most traders, who prefer to operate day to day in a small territory. This information provides some important insights into how agricultural trade could be improved. It suggests possible policy interventions in four main areas: increasing traders'asset base, reducing transaction risk, promoting more sophisticated business practices, and reducing physical marketing costs.Markets and Market Access,International Terrorism&Counterterrorism,Payment Systems&Infrastructure,Economic Theory&Research,Environmental Economics&Policies,International Terrorism&Counterterrorism,Economic Theory&Research,Banks&Banking Reform,Markets and Market Access,Access to Markets

Agricultural markets in Benin and Malawi

Based on original trader surveys, this paper examines how agricultural traders operate in Benin and Malawi. Results indicate that the largest transaction costs are search and transport. The use of modern technology is limited. Search methods rely principally on personal visits by the trader, and quality control requires the presence of the trader at the time of purchase. This increases costs, as the trader has to travel a lot, and makes it difficult for trading enterprises to grow. Since enterprises remain very small, personal transport and search time represent a non-negligible share of marketing costs.Traders, Transaction costs, Transport, Storage, Search, Marketing,

Successes in African agriculture

Using primary data from a survey of expert opinion, this paper identifies key successes emerging in African agriculture. Among these, major commodity-specific successes identified include breakthroughs in maize breeding across Africa, sustained gains in cassava breeding and successful combat of its disease and pests, control of the rinderpest livestock disease, booming horticultural and flower exports in East and Southern Africa and increased cotton production and exports in West Africa. Using a dynamic analytical framework, the paper attempts to identify key ingredients that appear necessary for building on these individual cases and expanding them into broad-based agricultural growth.Agricultural development projects Africa. ,Agriculture Africa Case studies. ,Surveys. ,

Of markets and middlemen

Using survey data on traders and brokers in the Ethiopian foodgrain market, this paper reveals that the brokerage institution is critical to market performance in that it enables traders to circumvent the commitment problem of long-distance trade with unknown partners. In the absence of grain standardization, public information, and legal contract enforcement, brokers act as inspectors and guarantors of each transaction. The paper analyzes the sources of commitment failure, the role and functions of brokers and the extent of brokerage use by brokers, and argues that agency relations are not based on ethnicity, depend on effective reputation rather than trust, and are structured in an incentive-compatible manner.trade ,

Market institutions, transaction costs, and social capital in the Ethiopian grain market:

Using a New Institutional Economics framework, this research report addresses a fundamental aspect of markets: how do buyers and sellers find each other and coordinate the transfer of goods? The report quantifies the transaction costs related to search faced by traders in Ethiopia and analyzes the role of brokers in minimizing these transaction costs. The transaction costs of market search are significant in the Ethiopian grain market. Estimated as the opportunity cost of labor time spent searching for a trading partner and the opportunity cost of holding capital fixed during that search, these costs represent one-fifth of all marketing costs. This research report demonstrates that traders minimize their transaction costs of search by using brokers, who enable them to exchange with unknown partners. The report also shows that at the level of the grain economy as a whole, brokers significantly increase the total economic welfare by enabling a more efficient allocation of search effort by traders. Thus, traders with relatively higher search efficiency and lower search costs choose to search on their own, while traders with lower search efficiency and higher search costs choose to use a broker.Grain trade Ethiopia., Institutional economics., Grain Ethiopia Marketing.,

Increasing returns and market efficiency in agricultural trade

"Using detailed trader surveys in Benin, Madagascar, and Malawi, this paper investigates the presence of increasing returns in agricultural trade. After analyzing margins, costs, and value added, we find little evidence of returns to scale. Motorized transport is found more cost effective for large loads on longer distances. But transporters pool quantities from multiple traders. Margin rates show little relationship with transaction size. Personal travel costs are a source of increasing returns, but the effect is small. Consequently, total marketing costs are nearly proportional to transaction size. Working and network capital are key determinants of value added. Constant returns to scale in all accumulable factors working capital, labor, and network capital cannot be projected. This implies that policies to restrict entry into agricultural trade are neither necessary nor useful. Governments should focus instead on technological and institutional innovations to upgrade agricultural markets." Authors' AbstractAgricultural trade ,Government policy ,Surveys ,Rate of return ,

Grain marketing policy changes and spatial efficiency of maize and wheat markets in Ethiopia

"In the context of on-going market reform in developing countries, there is a need for an improvement in the existing methods of spatial market efficiency analysis in order to better inform the debate toward designing and implementing new grain marketing policies, institutions, and infrastructure that facilitate the emergence of a well developed and competitive grain marketing system. The standard parity bounds model (PBM), while it overcomes many weaknesses of the conventional methods of spatial market efficiency analysis, it does not allow for the test of structural changes in spatial market efficiency as a result of policy changes. In this paper, building on the standard PBM, we develop an extended parity bounds model (EPBM). The EPBM is a stochastic gradual switching model with three trade regimes. The EPBM is estimated by maximum likelihood procedure and allows for tracing the time path and structural change in spatial market efficiency conditions due to the policy changes. We applied the EPBM to analyze the effect of grain marketing policy changes on spatial efficiency of maize and wheat markets in Ethiopia. The results show that the effect of policy changes on spatial market efficiency is not significant statistically in many cases; there is high probability of spatial inefficiency in maize and wheat markets before and after the policy changes. The implication of these results is that maize and wheat markets are characterized by periodic gluts and shortages, which can undermine the welfare of producers, grain traders and consumers. It is also observed that the nature of spatial inefficiency for maize and wheat markets is different implying that the two commodities might require different policy responses in order to improve spatial market efficiency. Maize traders made losses most of the time while wheat traders made excess profits most of the time covered by the study." Authors' AbstractStochastic analysis ,structural change ,

Trading up

"Wealthy countries' agricultural subsidies have also created unfair competition. African farmers not only have limited access to rich-country agricultural markets, but they also face unfair competition in their own domestic markets from subsidized imports of food staples. New challenges come from dramatically changed marketing chains that require African farmers to compete in markets that are more demanding in terms of product quality and food safety. What can be done to enhance market opportunities so that agriculture can become a more powerful engine of growth for the continent? Which markets and which products offer the greatest potential for raising incomes and food consumption? This brief addresses these questions and suggests policies that could help enlarge markets for African farmers." from Text

Smallholders' commercialization through cooperatives: A diagnostic for Ethiopia

"This paper examines the impact of cooperatives on smallholder commercialization of cereals, using detailed household data from rural Ethiopia. We review the involvement of cooperatives, in terms of who participates and where they are located. We then use the strong government role in promoting the establishment of cooperatives to assume that the decision of where to establish a cooperative is largely driven by external considerations, and is thus exogenous to the members themselves justifying the use of propensity-score matching in order to compare households that are cooperative members to similar households in comparable areas without cooperatives. Four conclusions are derived from the analysis. First, despite the spread of cooperatives – they existed in less than 15 percent of districts in 1994 and nearly 35 percent in 2005 – there are important disparities across regions. Within regions, cooperatives tend to be located in areas that already have better access to markets and lower exposure to price and environmental risks. Second, at the household level participation is only 9 percent, with poorer households less likely to participate. Third, while cooperatives obtain higher prices for their members, they are not associated with a significant increase in the overall share of cereal production sold by their members. Fourth, these average results hide considerable heterogeneity in the impact across households. In particular, we find smaller farmers tend to reduce their marketable surplus as a result of higher prices, while the opposite is true for larger farmers." from Authors' AbstractSmallholders, small farms, Marketing, Cooperatives, Commercialization, Cereal crops,
