In this paper, we explore the relationship between dietary diversity and income in pastoralist households in East Africa. Previous estimates of income elasticities of nutrient demand have ranged from zero to unity. However, these estimates are always based on the total income. One possible...

This paper explores whether there exist differences in groupwise poverty in Madagascar; that is, whether there is a pattern over time of consistently poorer performance among sub-populations readily identifiable by one or more identity markers. Three key messages come out of this analysis....

Little empirical work has quantified the transitory effects of macroeconomic shocks on farm-level production behaviour. We develop a simple analytical model to explain how macroeconomic shocks might temporarily divert managerial attention, thereby affecting farm-level productivity, but perhaps...

This paper uses detailed, transactions-level data and an innovative, structural-heteroskedasticity-in-mean estimation method to identify the determinants of livestock producer prices for pastoralists in the drylands of northern Kenya. The empirical results confirm the importance of animal...
