How much do our neighbors really know? The limits of community-based targeting

How much do our neighbors really know? The limits of community-based targeting

Social assistance programs in developing countries often rely on local community members to identify potential beneficiaries. As community members may observe neighbors’ welfare, their reports may capture transitory shocks better than the proxies typically observable by a centralized policy implementer. To test this, we conduct a lab-style experiment in Central Java, in which participants rank other community members’ welfare, using benchmarks that vary in sensitivity to transitory shocks, and target small cash transfers. We find little evidence that community-held welfare information better reflects transitory shocks and find that targeting decisions mostly depend on perceived differences in overall wealth.

Targeting of beneficiaries in chemical fertilizer subsidy programs: State of knowledge and evidence gaps

Targeting of beneficiaries in chemical fertilizer subsidy programs: State of knowledge and evidence gaps

Low and middle income countries have been facing mounting pressure from lenders and donors to eliminate or reform fertilizer subsidy programs, which can have distortionary market effects and negative environmental externalities. However, there is little systematic work understanding who these programs currently benefit both in theory and in practice, and hence who may be affected by policy reform. In this paper, we identify low and middle countries with active fertilizer subsidy programs, and characterize the targeting regime of each program based on both explicit and implicit criteria determining eligibility. Then in a selection of case studies, we explore which individuals are receiving subsidy benefits in practice. We find that while many fertilizer subsidy programs are meant to be universal, there are are additional implicit targeting criteria and/or informal targeting induced by supply shortfalls in many countries. Further, we find evidence that regardless of targeting regime, fertilizer subsidies are generally progressive, though this seems to be driven by the fact that the poor are often concentrated in the agricultural sector.

Production and consumption traits and the adoption of improved maize varieties: Evidence from seed sample packs and cooking demonstrations

Production and consumption traits and the adoption of improved maize varieties: Evidence from seed sample packs and cooking demonstrations

In developing countries, semi-subsistence farmers typically assume dual roles as both consumers and producers of the same crops, which shape their adoption decisions as they balance household food security with market-driven incentives. This study, conducted in eastern Uganda, employs a field experiment with two intervention arms to assess the relative importance of these factors in farmers’ decisions to adopt improved maize seed varieties. The first intervention focuses on production traits, distributing free sample packs of an improved hybrid maize variety to showcase benefits such as higher yields, pest resistance, and drought tolerance. The second intervention emphasizes consumption traits, offering cooking demonstrations and blind taste tests using flour from the same improved maize variety to highlight its taste, texture, and ease of preparation. Our findings reveal that while seed sample packs positively influenced farmers’ perceptions of both production and consumption traits, cooking demonstrations primarily affected perceptions of consumption qualities. We find some evidence that the cooking demonstrations and tasting sessions significantly boosted adoption of the improved maize seed variety promoted by the intervention. However, farmers who received seed sample packs tended to recycle the harvested grain as seed in subsequent seasons, thereby crowding out fresh seed purchases. This practice led to productivity losses, suggesting that the seed trial packs did not translate into lasting improvements in food security or increased market participation.
