Researchers in many fields, such as demography, economics, and sociology, have established various data collection methodologies and principles to answer a range of academic and policy questions on migration. Although the progress has been impressive, some basic challenges remain. This paper...

Discussions of high-skilled mobility typically evoke migration patterns from poorer to wealthier countries, which ignore movements to and between developing countries. This paper presents, for the first time, a global overview of human capital mobility through bilateral migration stocks by...

We exploit the bilateral and skill dimensions from recent data sets of international migration to test for the existence of Zipf's and Gibrat's Laws in the context of aggregate and high-skilled international immigration and emigration using graphical, parametric and non-parametric analysis. The...

It has been argued that the brain drain’s negative impact may be offset by the higher remittance levels skilled migrants send home. This paper examines whether remittances actually increase with migrants’ education level. The determinants of remittances it considers include migration levels...

In this paper, we simulate the labor market effects of net immigration and emigration during the 1990's in all OECD countries. To accomplish this, we are the first to employ a comprehensive database of migrant stocks, grouped by education level and country of origin/destination, for the years...

Labor markets are increasingly global. Overseas work can enrich households but also split them geographically, with ambiguous net effects on decisions about work, investment, and education. These net effects, and their mechanisms, are poorly understood. We study a policy discontinuity in the...

The welcome rise of replication tests in economics has not been accompanied by a single, clear definition of replication. A discrepant replication, in current usage of the term, can signal anything from an unremarkable disagreement over methods to scientific incompetence or misconduct. This...

The most basic economic theory suggests that rising incomes in developing countries will deter emigration from those countries, an idea that captivates policymakers in international aid and trade diplomacy. A lengthy literature and recent data suggest something quite different: that over the...

The current EU Asylum policy is widely seen as ineffective and unfair. We propose an EU-wide market for tradable quotas on both refugees and asylum-seekers coupled with a matching mechanism linking countries' and migrants' preferences. We show that the proposed system can go a long way towards...

A growing number of OECD countries are leaning toward adopting quality-selective immigration policies. The underlying assumption behind such policies is that more skill-selection should raise immigrants' average quality (or education level). This view tends to neglect two important dynamic...
