Transfers to individuals, firms, and regions are often regulated by threshold rules, giving rise to a regression discontinuity design. An example are transfers provided by the European Commission to regions of EU member states below a certain income level. Researchers have focused on estimation...

This paper studies the causal effect of sharing a common native language on international trade. Switzerland is a multilingual country that hosts four official language groups of which three are major (French, German, and Italian). These groups of native language speakers are geographically...

In this paper, we assess the role of skilled versus unskilled migration for bilateral trade using a flexible reduced-form model where the stocks of skilled and unskilled migrants at the country-pair level are determined as endogenous continuous treatments. The impact of different levels of...
