With comprehensive immigration reform dead for the foreseeable future, immigration laws enacted at the subfederal level -- cities, counties, and states -- have become even more important. Arizona has dominated media coverage and become the popular representation of the states’ response to...

We examine environmental factors as potential determinants of international migration. We distinguish between unexpected short-run factors, captured by natural disasters, as well as long-run climate change and climate variability. Building on a simple neo-classical model we use a panel dataset...

Climate change, especially the warming trend experienced by several countries, could affect agricultural productivity. As a consequence, rural incomes will change, and with them the incentives for people to remain in rural areas. Using data from 116 countries between 1960 and 2000, we analyze...

This paper investigates to what extent international migration can be explained by climatic variations. A gravity model of migration augmented with average temperature and precipitation in the country of origin is estimated using a panel data set of 142 sending countries for the period 1995 to...

Population movements will help people facing the impact of climate change. However, the resulting large scale displacements may also produce security risks for receiving areas. The objective of this paper is to empirically estimate if the inflows of climate-induced migrants increase the risk of...

Do natural disasters interplay with intensified international migration? Not only has the global migrant stock increased from 92 to 165 million between 1960 and 2000, but the frequency and magnitude of disasters have increased within the same period. In the face of exogenous shocks, migration is...

This paper sheds light on the apparent paradox, wherein populations adversely affected by climatic conditions fail to migrate as much as would otherwise be expected. Drawing on Hirschman's treatise on Exit, Voice and Loyalty, we develop a simple model, which highlights the theoretical case for a...

Slow onset climate change has the potential to cause significant migration flows. Scientists have recently made considerable efforts to quantify these flows based on empirical methods. However, the literature on international migration has failed to come to a clear conclusion as many studies...

The potential impact of climate change on international migration patterns has recently received considerable attention in both the public and academic debate. Yet, much of the empirical literature fails to find increases in international migration due to climate change. The current paper...
