    Comparative Experimental Evidence on Compliance with Social Distancing During the Covid-19 Pandemic
    (SSRN, 2020-07-04) Becher, Michael; Stegmueller, Daniel; Brouard, Sylvain; Kerrouche, Eric; https://ror.org/02jjdwm75
    Social distancing is a central public health measure in the fight against the COVID-19 pandemic, but individuals’ compliance cannot be taken for granted. We use a survey experiment to examine the prevalence of non-compliance with social distancing in nine countries and test pre-registered hypotheses about individual-level characteristics associated with less social distancing. Leveraging a list experiment to control for social desirability bias, we find large cross-national variation in adherence to social distancing guidelines. Compliance varies systematically with COVID-19 fatalities and the strictness of lockdown measures. We also find substantial heterogeneity in the role of individual-level predictors. While there is an ideological gap in social distancing in the US and New Zealand, this is not the case in European countries. Taken together, our results suggest caution when trying to model pandemic health policies on other countries’ experiences. Behavioral interventions targeted towards specific demographics that work in one context might fail in another.

    From Anti-vax Intentions to Vaccination: Panel and Experimental Evidence from Nine Countries
    (2022-02) Galasso, Vincenzo; Pons, Vincent; Profeta, Paola; Becher, Michael; Brouard, Sylvain; Foucault, Martial; https://ror.org/02jjdwm75
    Millions of people refuse COVID-19 vaccination. Using original data from two surveys in nine OECD countries, we analyze the determinants of anti-vax intentions in December 2020 and show that half of the anti-vax individuals were vaccinated by summer 2021. Vaccinations were more likely among individuals aged 50+, exposed to COVID-19, compliant with public restrictions, more informed on traditional media, trusting scientists, and less concerned about vaccines’ side effects. We run a survey experiment with informational messages. In EU countries, a message about protecting health largely increases vaccinations, even among anti-vax individuals. In the U.K. and U.S., a message about protecting the economy generates similar effects. Our findings suggest that informational campaigns should adopt adequate narratives and address concerns about vaccines’ side effects.
