Market channel and other drivers of tomato farmer production and handling practices in Nigeria
Non-contract farming arrangements remain the dominant marketing option for poor, often food-insecure smallholder farmers in low-and middle-income countries (LMICs), yet such farming arrangements are less studied than contract farming. Using a case study of 1,673 Nigerian tomato farmers, this study examined whether selling to midstream actors such as wholesalers and aggregators (via informal market arrangements) supports farmers’ adoption of good …
The role of genotyping in measuring improved variety adoption and impact
Why Contexts Matter for Gender Equal Outcomes in Research-Based Plant Breeding
Maize is an important crop for food security and livelihood improvement in Nigeria and elsewhere in Africa. Maize varieties that enable farmers to increase their productivity and profitability, for example, can help them achieve these development outcomes. Contextual factors shape women’s and men’s preferences for specific maize traits and varieties, thus influencing varietal uptake and the contribution varieties make towards securing people’s li…
Estimating seed demand in the presence of market frictions
This paper measures the effect of seed quality misperceptions on bidding behavior and demand for high-quality seed using an information-provision experiment within an incentive-compatible Vickery Second Price (SPA) auction mechanism that mimics seed purchasing decisions in the presence of seed market frictions. We find that most individuals are prone to quality misperception and revise their bids upwards (downwards) in response to positive (negat…
Misperceiving and misreporting input quality
Farmers in developing countries routinely misperceive or misreport input quality for various reasons, which introduces substantial measurement error in farm survey data. In this paper, we motivate and illustrate, both analytically and empirically, the inferential and behavioral implications of misperception and misreporting using a unique crop variety identification data from Nigeria. Using a non-parametric framework for testing the presence of m…
The poverty impacts of improved soybean technologies in Malawi
Improved soybean varieties and agronomic practices have been widely disseminated to smallholder farmers in Malawi over the last 15 years. However, there is no empirical evidence on the welfare impacts of adopting improved soybean technologies. This paper estimated the poverty impacts of adopting improved soybean technologies using data from 1,234 households in six soybean growing districts accounting for over 80% of the total soybean production i…
Agricultural technology adoption and household welfare
Previous studies on the adoption and impacts of improved crop varieties have relied on self-reported adoption status of the surveyed households. However, in the presence of weak variety maintenance and poorly functioning seed certification system, measurement errors in self-reported adoption status can be considerable. This paper investigates how such measurement errors can lead to biased welfare estimates. Using DNA-fingerprinting based varietal…
The poverty impacts of improved cowpea varieties in Nigeria
Adoption of improved agricultural technologies has long been recognized as critical for reducing poverty through increased productivity, incomes, and asset accumulation. Using a nationally representative survey data from a sample of over 1500 households in Nigeria, this paper evaluates the impacts of adoption of improved cowpea varieties on income and asset poverty reduction using an endogenous switching regression model. The results showed that …

Ethiopia’s Agricultural Transformation
This article explores empirical evidence on the relationship between agricultural transformation, ownership structure of agribusinesses, and employment creation in Ethiopia. It draws on secondary data to present evidence of Ethiopia’s agricultural transformation, employment trends, and the agribusiness sector’s contribution to employment generation. The country’s agricultural sector has shown signs of transformation in the form of both labour mov…
Impacts of extension access and cooperative membership on technology adoption and household welfare
This paper examines the impacts of access to extension services and cooperative membership on technology adoption, asset ownership and poverty using household-level data from rural Nigeria. Using different matching techniques and endogenous switching regression approach, we find that both extension access and cooperative membership have a positive and statistically significant effect on technology adoption and household welfare. Moreover, we find…
Productivity and Welfare Effects of Nigeria's e-Voucher-Based Input Subsidy Program
In an attempt to go beyond the so called " smart " subsidies, Nigeria has embarked on a potentially innovative mobile phone-based input subsidy program that provides fertilizer and improved seed subsidies through electronic vouchers. In this article, we examined the productivity and welfare effects of the program using household-level data from rural Nigeria. The article employed instrumental variable regression approach to control for the potent…
Forest dependence and income inequality in rural Ethiopia
The aim of the study was to examine the determinants of forest dependence and the role of community forest on income inequality in rural Ethiopia. Regression results, using Heckman’s two-stage estimation method, suggest that the probability of households’ participation in low-return forest activities is determined by farm size, number of male members in the household and distance from the forest plot to the household’s homestead. Further, the lik…
Climate variability, food security and poverty
Social network effects on the adoption of sustainable natural resource management practices in Ethiopia
Soil loss, nutrient depletion and land degradation contribute to the skimpy performance of smallholder agriculture and pose serious policy challenges in developing countries. Surprisingly, natural resource management practices that enhance sustainability while improving productivity have not been fully adopted despite continuous efforts of promotion. Using data collected from 2901 farm households in the Farmers Innovation Fund (FIF) of the World …
