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...

The cocoa sector in Ghana is one of few examples of an export commodity sector in an African country that has withstood the pressure to fully liberalize. Despite substantial government control over internal and external marketing via the Ghana Cocoa Board (COCOBOD), the current institutional...

"Using a two year panel dataset, this paper offers an empirical investigation of the unprecedented production boom episode observed in Ghana's cocoa sector between 2002 and 2004. We look at the technology of production underlying the years of the boom, and suggest that most of the rise was due...

The Ghana cocoa market has been extensively liberalised over the period since the mid 1980s. Three issues have been prominent in microeconomic research on the effects of liberalisation on agriculture. The first has been the size of any supply response, the second has been the effect on producers...

During the nineties, Rwandan households had to cope with severe shocks of war and genocide. In addition, two major structural problems in Rwanda, land scarcity and declining soil fertility, remain unsolved. How do Rwandan households manage? This is an important question from a development...

Knowledge of the marginal productivity of water is crucial for decisions about its allocation between uses, which is particularly important in the context of increasing competition for water. Using primary, plot-level panel data, this article estimates the marginal productivity of water from...

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....

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...
