We use event-study models based on staggered summer vacations in Germany to estimate the effect of school re-openings after the summer of 2021 on the spread of SARS-CoV-2. Estimations are based on daily counts of confirmed coronavirus infections across all 401 German counties. Our results are...

This study quantifies the disadvantage in the formation of literacy skills of immigrants that arises from the linguistic distance between mother tongue and host country language. Combining unique cross-country data on literacy scores with information on the linguistic distance between languages,...

This paper uses data from the 2010 American Community Survey (ACS) to study the returns to language skills of child and adult migrants in the US labor market. We employ an instrumental variable strategy, which exploits differences in language acquisition profiles between immigrants from English-...

There are various degrees of similarity between the languages of different immigrants and the language of their destination country. This linguistic distance is an obstacle to the acquisition of a language, which leads to large differences in the attainments of the language skills necessary for...

We study the impact of language deficiency on the health production of childhood migrants to Australia. Our identification strategy relies on a quasi-experiment comparing immigrants arriving at different ages and from different linguistic origins by utilising a measure of differences along a...

This paper is the first to estimate a causal effect of immigrant students' reading performance on their math performance. To overcome endogeneity issues due to unobserved ability, we apply an IV approach exploiting variation in age-at-arrival and the linguistic distance between origin and...

We study the impact of short-term exposure to ambient air pollution on the spread and severity of COVID-19 in Germany. We combine data on county-by-day level on confirmed cases and deaths with information on local air quality and weather conditions and exploit short-term variation in the...

We study the effect of ethno-linguistic classroom composition in college on educational performance, educational choices and post-graduation migration in a setting of quasi-random assignment to undergraduate seminars at a British university. We focus on two core variables: the share of...

This paper studies electoral effects of exposure to religious minorities in the context of Muslim communities in Germany. Using unique data on mosques' construction and election results across municipalities over the period 1980-2013, we find that the presence of a mosque increases political...

This paper studies the effect of the end of school summer breaks on SARS-CoV-2 cases in Germany. We exploit variation in the staggered timing of summer breaks across federal states which allows us to implement an event study design. We base our analysis on official daily counts of confirmed...
