Recent surveys of the literature on climate change and migration emphasize the important diversity of outcomes and approaches of the empirical studies. In this paper, we conduct a meta-analysis in order to investigate the role of the methodological choices of these empirical studies in finding...

This paper reviews the effect of environmental disasters on migration. Although there is an increase of environmental disasters and migration over the past years, the relationship is complex. While some authors find that environmental disasters increase migration, others show that they have only...

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...

For at least half a century, and building on observations first made a century earlier, the gravity model has been the most commonly‐used paradigm for understanding gross migration flows between regions. This model owes its success to, firstly, its intuitive consistency with migration...

There is a widespread policy view that a lack of job opportunities at home is a key reason for migration, accompanied by suggestions of the need to spend more on creating these opportunities so as to reduce migration. Self-employment is widespread in poor countries, and faced with a lack of...

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...

This paper uses state-level data on migration flows between Mexico and the U.S. from 1999 to 2011 to investigate the migration response to climate shocks and the mitigating impact of an agricultural cash-transfer program (PROCAMPO) and a disaster fund (Fonden). While lower than average...

Previous literature shows that internal migration rates are strongly procyclical. This would seem to imply that geographic relocation does not help mitigate negative local economic shocks during recessions. This paper shows that this is not the case. I document that net in-migration rates...
