Macro cross-country data and micro US county data indicate that resource rich regions have small and productive manufacturing sectors and large and unproductive non-manufacturing sectors. We suggest a process of specialization to explain these facts. Windfall revenue induces labor to move from...

This paper considers Bayesian nonparametric estimation of conditional densities by countable mixtures of location-scale densities with covariate dependent mixing probabilities. The mixing probabilities are modeled in two ways. First, we consider finite covariate dependent mixture models, in...

We construct a tractable discrete-time overlapping generations model of a closed economy and use it to study government redistribution of accidental bequests and private annuities in general equilibrium. Individuals face longevity risk as there is a positive probability of passing away before...
