There is a large literature which investigates the relationship between market concentration and innovation. It is difficult to find a suitable measure for innovative output. We use a rich dataset based on university trials of corn hybrids to estimate, using fixed effects, a production function....

The deregulation of Ghana’s domestic cocoa supply chain that took place in the early 1990s was expected to bring competition among different private buyers and to generate a number of production incentives to the farmers. Most notably, it was expected that competition would emerge by means of...

In the context of increasing competition for water, knowledge of the marginal productivity of water is crucial in determining its optimal allocation between users. Using primary, plot level panel data, this paper estimates the marginal productivity of water from supple- mentary irrigation in...

The slow adoption of innovations in less developed countries has long been a puzzle, given the high expected returns. This paper investigates the role of ambiguity-aversion as a fundamental behavioral determinant of technology adoption, motivated by the fact that, almost by definition, farmers...

Reducing Emissions through Deforestation and Degradation (REDD) is one of the few interventions to mitigate global warming being pur- sued at a global scale. Its implementation requires knowledge of the willingness to accept land use change contracts and its effectiveness re- quires its...

An argument in favor of the development of genetically modified (GM) hybrids is that their presence is considered to be risk decreasing., and hence, insurance premiums for US corn growers who plant approved hybrids have been reduced. In this study we investigate, using a large set of...

Using panel data from Vietnam, this paper estimates the determinants of consumption growth for the period 2002-04, using a microgrowth model. While controlling for individual heterogeneity, particular attention is devoted to the question of whether geography, broadly defined to include natural...
