Small farmers and traders often lack the market information they need to earn the most from their crop sales. This paper analyzes the effects of an action research experiment in central Malawi, in which four groups of smallholder farmers were provided with maize and soybean price information from a local commodity exchange during the 2019 marketing season, while four other groups of smallholder farmers did not receive this information. Using data from a panel survey of 399 farmers and 78 traders conducted before and after the main marketing season and using kernel propensity score matching approach to account for possible differences between the treated and non-treated farmers, we estimate the effects of the intervention on a number of outcome indicators. A before versus after analysis was also employed to evaluate changes in traders’ marketing outcomes. We find positive but statistically insignificant effects on maize and soybean selling prices, sales through structured markets and levels of commercialization after the intervention. We also find a negative and statistically significant effect on the quantity of maize sold by farmers, suggesting paradoxically that providing farmers with price information reduced their sales volumes. The proportion of traders aware of structured markets and their share of sales through structured markets also increased significantly after the intervention. The quantity of maize sold by traders as well as the selling prices for maize and soy-bean also increased significantly, although this may be due to factors other than the intervention. The study concludes that provision of price information alone is not enough to facilitate small farmers’ and traders’ use of structured markets. Greater effort is needed to sensitize farmers and traders on the quality and quantity requirements as well as the operations of structured markets.

Structured markets are organized platforms where economic agents such as farmers, traders, processors and financial institutions enter transparent and legal trading and financial arrangements (East Africa Grain Council 2013). Structured markets are important for the stabilization of volumes and prices of agricultural commodities (Hernandez et al. 2017) and diversification of foreign exchange earnings (Edelman et al. 2014). If supported by export mandates, structured markets for cereals and legumes could also limit informal cross-border trade and increase agricultural exports (Government of Malawi 2016). They could potentially also provide better statistics on volumes traded to aid in the planning, production, and marketing of crops in Malawi (Baulch and Gondwe 2017).

This open access textbook introduces the emerging field of Development Engineering and its constituent theories, methods, and applications. It is both a teaching text for students and a resource for researchers and practitioners engaged in the design and scaling of technologies for low-resource communities. The scope is broad, ranging from the development of mobile applications for low-literacy users to hardware and software solutions for providing electricity and water in remote settings. It is also highly interdisciplinary, drawing on methods and theory from the social sciences as well as engineering and the natural sciences. The opening section reviews the history of “technology-for-development” research, and presents a framework that formalizes this body of work and begins its transformation into an academic discipline. It identifies common challenges in development and explains the book’s iterative approach of “innovation, implementation, evaluation, adaptation.” Each of the next six thematic sections focuses on a different sector: energy and environment; market performance; education and labor; water, sanitation and health; digital governance; and connectivity. These thematic sections contain case studies from landmark research that directly integrates engineering innovation with technically rigorous methods from the social sciences. Each case study describes the design, evaluation, and/or scaling of a technology in the field and follows a single form, with common elements and discussion questions, to create continuity and pedagogical consistency. Together, they highlight successful solutions to development challenges, while also analyzing the rarely discussed failures. The book concludes by reiterating the core principles of development engineering illustrated in the case studies, highlighting common challenges that engineers and scientists will face in designing technology interventions that sustainably accelerate economic development. Development Engineering provides, for the first time, a coherent intellectual framework for attacking the challenges of poverty and global climate change through the design of better technologies. It offers the rigorous discipline needed to channel the energy of a new generation of scientists and engineers toward advancing social justice and improved living conditions in low-resource communities around the world.

This report summarizes the findings from an innovative study to collect the prices that farmers received for maize and soybeans during the 2020 main marketing season in Malawi. Between April and July, whenever they sold maize or soybeans, farmers were asked to report the prices they received by calling or texting a toll-free number managed by Farm Radio Trust. Reported prices were then compared to the minimum farmgate prices set by the Ministry of Agriculture and Food Security. Our findings show that 75 percent of maize farmers and 90 percent of soybean farmers sold their crops below the official minimum farmgate prices. On average, prices received by these farmers were approximately three-quarters of official minimum farmgate prices.

Surveys of the operation of agricultural traders in two Sub-Saharan African countries suggest that their performance would benefit from policies aimed at increasing their asset base, reducing transaction risk, promoting more sophisticated business practices, and reducing physical marketing costs.Drawing on original surveys of agricultural traders, Fafchamps and Gabre-Madhin 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.This paper - a product of Rural Development, Development Research Group - is part of a larger effort in the group to understand the operation of commodity markets in rural areas. The study was funded by the Bank's Research Support Budget under the research project quot;Markets for Agricultural Inputs in Sub-Saharan Africaquot; (RPO 683-48).

Seasonal analysis of the structure, conduct, and performance (SCP) of markets for staple crops has received relatively little attention in food policy analysis yet it has important implications for food and nutrition security. This study employs a mixed methods approach to analyze the SCP of maize markets in Malawi in the 2018/19 main harvest and lean seasons. We interviewed 749 traders from 74 markets across 8 districts, held 28 focus group discussions (FGD) with a total of 480 farmers and analyzed daily and weekly price data from 13 regional markets. The structure of maize markets was explored by examining marketing channels, barriers to entry and the competitiveness of different tiers of the marketing chain. Inequality in sales revenues, switches in trader types between seasons, quality and weights standardization, and the behavior of traders were used to examine market conduct. Performance was assessed by examining traders’ costs and margins, and the spatial and temporal integration of maize markets. We find that Malawi’s maize market is pyramidal in structure and highly competitive at lower tiers of trade but ‘oligopolistic’ at higher tiers. The market channels vary across seasons with switches between trader types and instances of rural-urban trade reversals. There is considerable inequality of sales revenues among traders of similar capacities, and a widespread lack of structured trading despite existing institutions. A high ratio of marketing costs to revenue suggests marketing inefficiencies. Malawi maize prices were highly seasonal and more volatile than neighboring countries. In contrast to previous studies, our findings show weak spatial integration of markets and slow price adjustments to long-run equilibrium values even among short-distance market pairs. The study highlights five pathways to improving Malawi’s maize marketing system: (1) increased policy predictability to promote private-sector investment; (2) institutionalization of quality grades and standardization of weights and measures; (3) increased commercialization of smallholder maize production; (4) investment in enabling infrastructure; and (5) the promotion of structured trading.
