We study the relationship between geography and growth. To do so, we first develop a dynamic spatial growth theory with realistic geography. We characterize the model and its balanced growth path and propose a methodology to analyze equilibria with different levels of migration frictions. We...

This paper presents a critical survey of theories of migration, their welfare and policy implications and their empirical relevance. We also develop some extensions to the theory beginning with a general encompassing model of migration which treats the Harris and Todaro (HT) model as a special...

As exemplified in the 1995 Mediterranean Declaration of the European Union, migration has become a major concern for European development policies. By enhancing socio-economic conditions through development cooperation, a reduction of South-North migration flows is envisaged. This new approach...

Mobility of workers involves flows of labour, human capital and other production factors and thus contributes to a more efficient allocation of resources. Besides these effects on allocative efficiency, migrant flows affect relative wages and also change the international and national...

We investigate the origin and evolution of the legal institution of citizenship from a political economy perspective. We compile a new data set on citizenship laws across countries of the world which documents how these institutions have evolved in the postwar period. We show that, despite a...

By means of a descriptive survey of theoretical literature we first work out the potential determinants that may drive international migration from developing to developed countries. In addition, we look at the relationship between trade, development and migration. Empirical studies focusing on...

High-skilled emigration has been found to affect developing economies via different channels. With a calibrated general equilibrium framework, this paper finds that the short-run impact of brain drain on resident human capital is extremely crucial, as it does not only determine the number of...

This paper documents a stylized fact not well appreciated in the literature. The Third World has been undergoing an emigration life cycle since the 1960s, and, except for Africa, emigration rates have been level or even declining since a peak in the late 1980s the early 1990s. The current...

We study the determinants of 19th century mass migration with special attention to the role of institutional factors beside standard economic fundamentals. We find that economic forces associated with income and demographic differentials had a major role in the determination of this historical...

OECD governments note rising immigration with alarm and grapple with policies aimed at selecting certain migrants and keeping out others. Economists appear to be well armed to advise governments since they are responsible for an impressive literature that examines the characteristics of...
