While policy makers, international organizations and academics are increasingly aware of the economic effects of emigration, the potential political effects remain understudied. This book maps the nature of the relationship that links emigration and political development. Jonathon W. Moses explores the nature of political development, arguing that emigration influences political development. In particular, he introduces a new cross-national database of annual emigration rates and analyzes specific cases of international emigration (and out-migration within countries) under varying political and economic contexts.
