Shocks and Vulnerability in Rural Tanzania

open access: yesReview of Development Economics, EarlyView.
ABSTRACT This paper examines the relative importance of idiosyncratic and covariate shocks in shaping household vulnerability to poverty in rural Tanzania. Using five rounds of the Tanzanian National Panel Survey and a three‐level multilevel modeling framework, we account for the hierarchical structure of the data and decompose consumption variance ...
