We study international migration responses of the super-rich to taxes using UK administrative data and a difference-in-differences design. We exploit a reform that removes access to a tax break on foreign income for foreigners based on their number of years in the UK, allowing us to compare...

The Middle East was once seen as a medieval great globalized force. Nowadays it shows one of the lowest intra-regional trade in the world and therefore it is claimed that the region is poorly integrated. Yet, with the steady .ow of workers across national borders of the Middle East is this...

We develop a model to explain two-way migration of high-skilled individuals between countries that are similar in their economic characteristics. High-skilled migration results from the combination of workers whose abilities are private knowledge, and a production technology that gives...

This paper develops and estimates a dynamic model where individuals differ in ability and location preference to evaluate the mechanisms that affect the evolution of immigrants' careers in conjunction with their re-migration plans. Our analysis highlights a novel form of selective return...

We carried out two multinational surveys to analyze aspirations and intentions to emigrate, and how these are linked to each other. One survey covered language course participants in 14 countries, and another students in 6 countries. We identify two groups that have been largely neglected in...

Mobility of highly-skilled workers affects and is affected by labor market conditions, taxes, and other policies. This paper documents the demographic and fiscal importance of international migration, especially in aging societies, reviews the efficiency and distributional effects of mobility,...

Migration of young workers (as distinct from retirees), even when driven in by the generosity of the welfare state, slows down the trend of increasing dependency ratio. But, even though low-skill migration improves the dependency ratio, it nevertheless burdens the welfare state. Recent studies...

Do migrants shape the dynamic comparative advantage of their sending and receiving countries? To answer this question we study the drivers of knowledge diffusion by looking at the dynamics of the export basket of countries, with particular focus on migration. The fact that knowledge diffusion...

In light of the recent feminization of migration, we empirically explore to what extent worldwide female migration can be explained by perceived gender discrimination. Thanks to unique individual level data, we track women's willingness and preparation to emigrate from 150 countries between...
