AbstractIn the absence of effective vaccination, mass testing and quarantining of positive cases and their contacts could help to mitigate pandemics and allow economies to stay open. We investigate the effects of repeated mass testing on the COVID-19 pandemic caused by the SARS-CoV-2 virus, using data from the first ever nationwide rapid antigen testing implemented in Slovakia in autumn 2020. After the first round of testing, only districts above an ex ante unknown threshold of test positivity were re-tested. Comparing districts above and below the threshold, we provide evidence that repeated mass antigen testing can temporarily reduce the number of new infections. Our results suggest that mass testing coupled with the quarantining of positive cases and their contacts could be an effective tool in mitigating pandemics. For lasting effects, re-testing at regular intervals would likely be necessary.

Using linked vacancy-employer-employee data from Austria, we investigate how monopsony power affects firms' posting behavior and wage negotiations. Consistent with theoretical predictions, we find that firms with greater monopsony power post lower wages and offer fewer non-wage amenities, suggesting that wages and non-wage benefits are complementary. However, we find no evidence that monopsonistic firms demand higher levels of skill or education. Instead, our results indicate that they require more basic skills, particularly those related to routine tasks. On the workers' side, we find that employees hired in monopsonistic labor markets face significantly lower wages, both initially and in the long run. These lower wages are driven by both lower posted wages and reduced bargaining power, as well as reduced opportunities to climb the wage ladder later.
