The consequences of climate change for agriculture and food security in developing countries are of serious concern. Due to their reliance on rain-fed agriculture, both as a source of income and consumption, many low-income countries are considered to be the most vulnerable to climate change....

Although Mozambique has considerable agricultural potential, rural poverty remains extremely high. This paper examines the extent to which global and domestic price distortions affect agricultural production and national poverty. The author develops a computable general equilibrium (CGE) and...

Fuel diversification implies the selection of a mix of generation technologies for long-term electricity generation. The goal is to strike a good balance between reduced costs and reduced risk. The method of analysis that has been advocated and adopted for such studies is the mean-variance...

Motivated by a lack of Engel flexibility in commonly used demand systems, Rimmer and Powell developed a new demand system. This system, referred to AIDADS, is implicitly, directly additive, possesses marginal budget shares and thus Engel elasticities, that vary nonlinearly with expenditure such...

A recently developed demand system, nicknamed AIDADS (An Implicit, Directly Additive Demand System), offers an approach to capturing consumer preferences across a wide range of expenditure levels. AIDADS generalizes the LES by assuming marginal budget shares vary with utility and hence with...

This paper proposes a new method for ex ante analysis of the poverty impacts arising from policy reforms. Three innovations underlie this approach. The first is the estimation of a global demand system using a combination of micro-data from household surveys and macro-data from the International...
