We present a theory on migration of dual-earner couples, and test it in the context of international migration. Our model predicts that the probability that a couple emigrates increases in the earnings of the primary earner. The effect of the earnings of the secondary earner may go either way....

Early non-pharmaceutical interventions (NPI) significantly reduced the death toll of the COVID-19 pandemic. Yet, there are vast differences in how quickly governments implemented NPIs. In this paper, we analyze the role of public attention, measured as the share of daily Google searches in a...

In European Welfare States, low-skilled workers are typically unionized, while the wage formation of high-skilled workers is more competitive. To focus on this aspect, we analyze how flexible international outsourcing and labour taxation affect wage formation, employment and welfare in dual...

We suggest a political economy explanation for the stylized fact that intragenerationally more redistributive social security systems are smaller. Our key insight is that linking benefits to past earnings (less redistributiveness) reduces the efficiency cost of social security (due to endogenous...

The mobility of labor reduces national incentives to invest in internationally applicable education. The European Union could overcome this by allowing member states to institute graduate taxes or income-contingent loans, collected also from migrants. This paper presents calculations on how a...

About 1.4 million refugees and irregular migrants arrived in Europe in 2015 and 2016. We model how refugees and irregular migrants are self-selected. Using unique datasets from the International Organization for Migration and Gallup World Polls, we provide the first large-scale evidence on...
