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...

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...

International migration is maybe the single most effective way to alleviate global poverty. When a given host country allows more immigrants in, this creates costs and benefits for that particular country as well as a positive externality for individuals and governments who care about world...

We empirically investigate the relationship between a country's economic complexity and the diversity in the birthplaces of its immigrants. Our cross-country analysis suggests that birthplace diversity is strongly and positively associated with economic complexity. This holds particularly for...
