Deaton s analysis of the problems with poverty counts and suggestions for improvement, including issues needing further research, are based on two distinct stages in counting the poor. At the first or international stage, a world poverty line is set and used to derive comparable poverty lines...

Most measures of vulnerability are a-theoretic and essentially static. In this paper we use a stochastic Ramsey model to find a household's optimal welfare and we measure vulnerability as the shortfall from the welfare attained if the household consumed permanently at the poverty line. The...

Using a unique panel data set for rural households in Zimbabwe we estimate amicroeconomic model of growth under uncertainty, a stochastic version of the Ramsey modelwith livestock as the single asset. We use the estimation results in simulation experiments(over a 20-year period) to quantify the...
