Labour Market Shocks and Parental Investments during the Covid-19 Pandemic.

This paper studies spill-over effects of parental labour market shocks at two time points in the Covid-19 crisis: right after its onset in April 2020, and in January 2021. We use rich data from the UK to look at the consequences of immediate and persistent shocks that hit parents' economic livelihoods. These negative labour market shocks have substantially larger impacts when suffered by fathers than by mothers.

Schools under mandatory testing can mitigate the spread of SARS-CoV-2.

We use event study models based on staggered summer vacations in Germany to estimate the effect of school reopenings after the summer of 2021 on the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Estimations are based on daily counts of confirmed coronavirus infections across all 401 German counties. A central antipandemic measure in German schools included mandatory rapid testing multiple times per week.

Pandemic meets pollution: Poor air quality increases deaths by COVID-19.

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 at the county-by-day level on confirmed cases and deaths with information on local air quality and weather conditions. Following Deryugina et al.

Language Barriers and Immigrant Health.

We study the impact of language deficiency on the health status of childhood migrants to Australia. Our identification strategy relies on a quasi-experiment comparing immigrants arriving at different ages and from different linguistic origins. In the presence of considerable non-classical measurement error in self-reported language proficiency, our results provide lower and upper bounds for a strong negative effect of English deficiency on health of between one half and a full standard deviation in the health score.
