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...

This paper explores the idea that competitive seed systems may underserve farmers in small, agro-ecological niches, leaving those farmers less productive and poorer than they need be. We develop a theoretical model of the confluence of demand and supply factors that can result in such an...

We examine the economic impact of high-yielding crop varieties (HYVs) in developing countries 1960-2000. We use time variation in the development and diffusion of HYVs of 10 major crops, spatial variation in agro-climatically suitability for growing them, and a differences-in-differences...

A large fraction of Uganda's population continues to earn a living from quasi-subsistence agriculture. This paper uses a static general equilibrium model to explore the relationships between high transportation costs, low productivity, and the size of the quasi-subsistence sector. We...

According to national accounts data, value added per worker is much higher in the non-agricultural sector than in agriculture in the typical country, and particularly so in developing countries. Taken at face value, this "agricultural productivity gap" suggests that labor is greatly misallocated...

Standard measures of productivity display enormous dispersion across farms in Africa. Crop yields and input intensities appear to vary greatly, seemingly in conflict with a model of efficient allocation across farms. In this paper, we present a theoretical framework for distinguishing between...

In most developing countries, there is a large gap in average consumption per capita between urban and rural areas. One appealing interpretation of this gap is that it reflects a spatial equilibrium, in which the higher consumption levels of urban areas are offset by lower non-monetary...

Utilizing a multi-year, spatially diversified randomized controlled trial spanning two African countries, this paper explores whether bundled genetic and financial technologies can boost the resilience and productivity of small-scale farmers who are exposed to significant risk. The analysis...
