We use a multilevel approach to characterize the relationship between weather shocks and (internal and international) migration intentions. We combine individual survey data on migration intentions with measures of localized weather shocks for Western African countries over 2008-2016. A...

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...

The effect of immigration on host and origin countries is mediated by the way migrants take their labor supply decisions. We propose a simple way of integrating the traditional random utility maximization model used to analyze location decisions with a classical labor demand function at...

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...

Migration flows are shaped by a complex combination of self-selection and out-selection mechanisms. In this paper, we analyze how existing diasporas (the stock of people born in a country and living in an another one) affect the size and human-capital structure of current migration flows. Our...

Ecuador experienced an unprecedented wave of international migration since the late 1990s, triggered by a severe economic and financial crisis. This paper gathers individual-level data from Ecuador and the two main destinations of Ecuadorian migrants: the US and Spain. First, we provide a...

This paper looks at the impact of networks on international migration flows to OECD countries. In particular, we look at whether diaspora effects are different across education levels and gender. Using new data allowing to include both dimensions, we are able to analyze the respective impact of...

Many empirical studies on the determinants of international migration flows rely exclusively on macro data, and do not account for migrants' self-selection. We analyze a very interesting episode in international migration for which we are able to gather individual-level data covering all...
