摘要
Most studies examining the dynamics of welfare have found large fluctuations in consumption over relatively short periods, suggesting substantial short-run movements in and out of poverty. The consequence is that cross-section poverty research may not be able to identify the pool: In this study, we explore this short-run variability further: We use a data set on a panel of 1450 households in different communities in rural Ethiopia, surveyed thrice, over 18 months. On average year-to-year poverty is very similar However we find high variability in consumption and poverty, over the seasons and year-by-year Econometric analysis suggests that consumption is affected by idiosyncratic and common shocks, including rainfall and household-specific crop failure, while households respond to seasonal incentives related to changing labour demand and prices. The results imply that a larger number of households are vulnerable to shocks than implied by the standard poverty statistics, while some of the non-poor in these statistics are in fact otherwise poor households temporally boosting their consumption as an optimal response to changing seasonal incentives.
