摘要：Households in developing countries are frequently hit by severe idiosyncratic
and covariate shocks resulting in high consumption volatility. A household’s
currently observed poverty status might therefore not be a good indicator of the
household’s general poverty risk, or in other words its vulnerability to
poverty. Although several measurements to analyze vulnerability to poverty have
recently been proposed, empirical studies are still rare as the data
requirements for these measurements are often not met by the surveys that are
available for developing countries. In this paper, we propose a simple method to
empirically assess the impact of idiosyncratic and covariate shocks on
households’ vulnerability, which can be used in a wide context as it relies on
commonly available living standard measurement surveys. We apply our approach to
data from Madagascar and show, that whereas covariate and idiosyncratic shocks
have both a substantial impact on rural households’ vulnerability, urban
households’ vulnerability is largely determined by idiosyncratic shocks.
