Migration and the environment: A look across perspectives

The decisions related to migration – where to live, when to move, and where to move – have a long history in economics. Different fields, within economics and outside economics, have developed different empirical methods to study migration and its consequences. However, these literatures rarely cite each other and there is little crossover between them. The purpose of this paper is twofold. First, to provide a simple theoretical framework for understanding general equilibrium effects in migration models that can help researchers think through the specific contexts in which these will be a problem for reduced form estimation. Second, to examine the different literatures in economics that have addressed the question of the effects of environmental amenities on migration with an eye to the differences across them and the way they can complement each other.
