Schooling has been shown to provide substantial externality benefits by increasing farm output and shifting the production frontier outwards. This paper investigates the role of schooling at the household- and site-levels in the adoption and diffusion of agricultural innovations in rural...

Agricultural productivity growth in sub-Saharan Africa has been a qualified success. Total factor productivity growth has increased rapidly since the early 1980s. By the early 2000s, average annual TFP growth was roughly four times faster than it had been 25 years earlier. This period of...

Low adoption of agricultural technologies holds large productivity consequences for developing countries. Agricultural extension services counter information failures by deploying external agents to communicate with farmers. However, social networks are recognized as the most credible source of...

Much has been written on the determinants of input and technology adoption in agriculture, with issues such as input availability, knowledge and education, risk preferences, profitability, and credit constraints receiving much attention. This paper focuses on a factor that has been less well...

In this paper we explore whether low rates of sustained technology use can be explained by heterogeneity in returns to adoption.  To do so we evaluate impacts of the Cocoa Abrabopa Association, which provided a package of fertilizer and other inputs on credit to cocoa farmers in Ghana.  High...

Increasingly, development projects list social capital development and network brokerage among their objectives.  How do we quantitatively evaluate such initiatives?  Best practice, diff-in-diff methods may be impossible or too costly.  Here, we try using data that are byproducts of the...

Since independence a quiet revolution has taken place in maize production in the Sahel with Mali increasing production more than ten-fold and yields going up ~2% a year. This research work uses farm level panel data from southern Mali's maize growing regions to demonstrate this success in...

The role of twentieth-century agricultural mechanization in changing the productivity, employment opportunities, and appearance of rural America has long been appreciated. Less attention has been paid to the impact made by farm tractors, combines, and associated equipment on the standard of...

The share of U.S. corn production used to produce ethanol increased from 12.4% in the 2004/05 crop year to over 38.5% in the 2010/11 crop year, and remained at that high level in 2011/12. Even after accounting for return of by-products to the feed market, this is a large and persistent new...

We show that much of Africa's recent growth and poverty reduction can be traced to a substantive decline in the share of the labor force engaged in agriculture. This decline has been accompanied by a systematic increase in the productivity of the labor force, as it has moved from low...
