Classic theories suggest that common pool resources are subject to overexploitation. Community-based resource management approaches may ameliorate "tragedy of the commons" effects. Using a randomized evaluation in Namibia's communal rangelands, we find that a comprehensive four-year program to...

Risk often inhibits on-farm investment by smallholder farmers. Recent evidence indicates that index insurance and stress tolerant seeds can separately and partially offset this risk effect. In this study, we explore whether the complementarities between these two risk management technologies can...

This paper explores the idea that a competitive seed system may systematically underserve farmers in small, agro-ecological niches, leaving potential yield gains on the table and farmers in these areas less productive and poorer than they need be. We develop a simple theoretical model that...

Work in positive psychology decomposes hope into aspirations, agency, and pathways. Operating in the context of an economic model developed with this framework, we review the literature on hope from philosophy, theology, psychology, and its relationship to emerging work on aspirations in...

The mechanism(s) that generate measurement error matter to inference. Survey measurement error is typically thought to represent simple misreporting correctable through improved measurement. But errors might also or alternatively reflect respondent misperceptions that materially affect the...

Progressively targeted cash transfers remain the dominant policy response to chronic poverty in developing countries. But are there alternative social protection policies that might have larger poverty impacts over time for the same public expenditure? To explore this question, this paper...

This paper studies the causal mechanisms behind persistent poverty. Using original data on Boran pastoralists of southern Ethiopia, we find that heterogeneous and nonlinear wealth dynamics arise purely in adverse states of nature. In favorable states, expected herd grow is quasi-linear and...
