We use SVAR models for 18 economies to estimate how much fiscal policy deviated from pre-pandemic norms during the Covid-19 pandemic. For most countries, fiscal policy was more expansive than the pre-pandemic norm predicts based on the state of the economy during the pandemic. The size of the...

This paper investigates the factors that contributed to the proliferation of online COVID skepticism on Twitter across Italian municipalities. We demonstrate that socio-demographic factors are likely to mitigate the emergence of skepticism, while populist political leanings were more likely to...

How much did young people suffer from the COVID-19 pandemic? A growing number of studies address this question, but they often lack a comparison group that was unaffected by the pandemic, and the observation window is usually short. Here, we compared the 2-year development of life satisfaction...

This study uses the Progress in International Reading Literacy Study (PIRLS) data, the only cross-national data having measured educational achievement during the COVID-19 pandemic, to investigate educational achievement decline of fourth graders across 21 European countries between 2016 and...

In times of crises, democracies face the challenge of balancing effective interventions with civil liberties. This study examines German states' response during the early stages of the COVID-19 pandemic, focusing on the interplay between civil liberties and public health goals. Using state-level...

This paper proposes a structural econometric approach to estimating the basic reproduction number (R0) of Covid-19. This approach identifies R0 in a panel regression model by filtering out the effects of mitigating factors on disease diffusion and is easy to implement. We apply the method to...

We assess whether the COVID-19 vaccine induces COVID-19 risky behavior (e.g., going to bars and restaurants) and thus reduces vaccine efficacy. A key empirical challenge is the endogeneity bias when comparing risk-taking by vaccination status since people choose whether to get vaccinated. To...

We study determinants of COVID-19 vaccine donations from recipients' perspective, especially considering supply chain and institutional weakness (corruption) aspects. Results, based on data from more than 131 nations, show that strengthened supply chains reduced donations. The impacts of...

Using a randomized experiment in 200 Bangladeshi villages, we evaluate the impact of an over-the-phone learning support intervention (telementoring) among primary school children and their mothers during Covid-19 school closures. Post-intervention, treated children scored 35% higher on a...
