We build a 4-equation model of the inflation process in South Africa (which has recently adopted inflation targeting), including the exchange rate, consumer prices, producer price, and import prices. This provides useful information on the speed and extent of exchange rate pass- through, and...

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...

Using panel data from villages in rural Ethiopia, the paper studies the determinants of consumption growth (1989-97), based on a microgrowth model, controlling for heterogeneity. Consumption grew substantially, but with diverse experiences across villages and individuals. A key focus is on...

Using detailed trader surveys in Benin, Madagascar and Malawi this paper investigates the presence of increasing returns in agricultural trade. After analyzing margins, costs, and value added, we find little evidence of returns to scale. Motorized transport is found more cost effective for large...

Elasticities of demand and supply for South African manufactured exports are estimated using a vector error correction model in order to address simultaneity and non-stationarity issues. Demand is highly price- elastic, with elasticities ranging from -3 to –6. The price elasticity of supply is...

In this paper, we present a new multithreaded framework for information extraction with Java in heterogeneous enterprise application environments, which frees the developer from having to deal with the error-prone task of low-level thread programming. The power of this framework is demonstrated...

This paper uses survey data to investigate empirically the importance of corruption in determining firm performance in Africa. We allow for the possibility of perception bias on the part of the respondents and for corruption being endogenous. We find that corruption is linked to significant...

This paper revisits the contested issue of the impact of agricultural extension on farm productivity. Often studies in this field suffer from a bias either due to self-selection of the best farmers for the extension services or to endogenous placement of the programme. The panel dataset...

This paper investigates the relationship between poverty and crime. Following a disputed presidential election, fuel supply to the highlands of Madagascar was severely curtailed in early 2002, resulring in a massive - if temporary - increase in poverty. Using original survey data collected in...

This paper uses survey data to investigate empirically the importance of corruption in determining firm performance in Africa. We allow for the possibility of perception bias on the part of the respondents and for corruption being endogenous. We find that corruption is linked to significant...
