We study incumbency advantage in markets with positive consumption externalities. Users of an incumbent platform receive stochastic opportunities to migrate to an entrant. They can accept a migration opportunity or wait for a future opportunity. In some circumstances, users have incentives to...

The purpose of this study is to examine the impact of air pollution (measured by satellite data of Aerosol Optical Depth (AOD)) on net outmigration. Using data from the 2011 and 2016 National Population and Housing Censuses for 31 provinces of Iran and applying a panel fixed effects estimation...

This paper estimates the impacts of climate change in sub-Saharan Africa (SSA) on migration and other economic outcomes. I develop a quantitative spatial model that captures the role of trade networks, migration barriers, and agricultural yields on the geography of the economy. I combine the...

We study OECD countries that differ in immigration policies but share a high level of human capital. We find significant negative statistical relationship between 16 years lagged fertility and the rate of immigration in a panel of 23 countries, which indicates that immigration compensates for...

Does the emigration of skilled individuals necessarily result in losses for source countries due to the brain drain? Combining industry-level patenting and migration data from 32 European countries, we show that emigration in fact positively contributes to innovation in source countries. We use...

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...

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...
