Recent evidence suggests that vaccination hesitancy is too high in many countries to sustainably contain COVID-19. Using a factorial survey experiment administered to 20,500 online respondents in Germany, we assess the effectiveness of three strategies to increase vaccine uptake, namely, providing freedoms, financial remuneration, and vaccination at local doctors. Our results suggest that all three strategies can increase vaccination uptake on the order of two to three percentage points (PP) overall and five PP among the undecided. The combined effects could be as high as 13 PP for this group. The returns from different strategies vary across age groups, however, with older cohorts more responsive to local access and younger cohorts most responsive to enhanced freedoms for vaccinated citizens.

Much like Brexit, the Greek bailout referendum of 2015 could have been a watershed event that significantly affected the European Economic and Monetary Union and possibly the European Union as a whole. While the referendum did not live up to the hype, the fact remains that the Greek people decided to risk ‘exit’ and reject their international creditors’ bailout terms. In this article, we explore how the cycle of sovereign debt crisis, the externally imposed austerity and the resulting recession affected the outcome of that referendum. We further provide a limited test for the ‘left-behind’ hypothesis, which has been a prominent explanation for recent ‘unexpected’ or ‘surprising’ choices that have been made at the polls. Using municipality data and novel data sources, such as night-time light transmission, we provide aggregate-level support for our expectations.
