Combating COVID-19 with charisma: Evidence on governor speeches in the United States.

Using field and laboratory data, we show that leader charisma can affect COVID-related mitigating behaviors. We coded a panel of U.S. governor speeches for charisma signaling using a deep neural network algorithm. The model explains variation in stay-at-home behavior of citizens based on their smart phone data movements, showing a robust effect of charisma signaling: stay-at-home behavior increased irrespective of state-level citizen political ideology or governor party allegiance. Republican governors with a particularly high charisma signaling score impacted the outcome more relative to Democratic governors in comparable conditions. Our results also suggest that one standard deviation higher charisma signaling in governor speeches could potentially have saved 5,350 lives during the study period (02/28/2020-05/14/2020). Next, in an incentivized laboratory experiment we found that politically conservative individuals are particularly prone to believe that their co-citizens will follow governor appeals to distance or stay at home when exposed to a speech that is high in charisma; these beliefs in turn drive their preference to engage in those behaviors. These results suggest that political leaders should consider additional "soft-power" levers like charisma-which can be learned-to complement policy interventions for pandemics or other public heath crises, especially with certain populations who may need a "nudge."

Acceptability of COVID-19 Vaccine Among Hospital Employees in the Department of Paediatrics, Gynaecology and Obstetrics in the University Hospitals of Geneva, Switzerland.

BACKGROUND AND AIMS: COVID-19 vaccination has been in the spotlight for almost a year now, both within the scientific community and in the general population. The issue of healthcare workers' (HCWs) hesitancy is particularly salient, given that they are at the forefront of the fight against COVID-19. Not only could unvaccinated HCW spread the disease, but HCWs are also critical messengers in building confidence towards COVID-19 vaccines. The goal of this study was to examine the perception of COVID-19 risk and of its vaccine acceptance among employees (i.e., HCW plus administrative staff) in the Department of Paediatrics, Gynaecology and Obstetrics at the University Hospitals of Geneva, for the purpose of drawing lessons on the determinants of vaccination morale. METHODS: We conducted an anonymous online survey comparing vaccination attitudes among vaccinated and unvaccinated workers in June 2021. It included questions on perception of COVID-19 risks and COVID-19 vaccines. Vaccination was not mandatory in our institution but was strongly recommended. RESULTS: In June 2021, 66% of the 1,800 employees of our department had received two doses of COVID-19 vaccine by the time of the survey. Among the employees, 776 participated (43%) to the survey, and among them 684 (88%) had chosen to be vaccinated. Participants working for longer in a hospital, with a chronic disease and a household contact with chronic disease were more likely to be vaccinated. Doctors were twice as likely to be vaccinated than nurses. Among unvaccinated hospital employees, 48 (52%) responded that they would not change their mind. Further, 35 (38%) were not feeling in danger of contracting severe COVID-19, and 32 (35%) had fears about possible side effects of COVID-19 vaccines that they wanted to discuss with a specialist. CONCLUSION: Our study indicates that, while two-third of the employees had been vaccinated, quite many were still hesitant. The unvaccinated explained their choice by not feeling at risk of complicated COVID-19, and because of fear of possible side effects associated with the vaccine. Investments in COVID-19 vaccine education is a critical component for increasing vaccine acceptance among the unvaccinated.

Saving the world from your couch: the heterogeneous medium-run benefits of COVID-19 lockdowns on air pollution

In Spring 2020, COVID-19 led to an unprecedented halt in public and economic life across the globe. In an otherwise tragic time, this provides a unique natural experiment to investigate the environmental impact of such a (temporary) ‘de-globalization’. Here, we estimate the medium-run impact of a battery of COVID-19 related lockdown measures on air quality across 162 countries, going beyond the existing short-run estimates from a limited number of countries. In doing so, we leverage a new dataset categorizing lockdown measures and tracking their implementation and release, extending to 31 August 2020. We find that domestic and international lockdown measures overall led to a decline in PM2.5 pollution by 45% and 35%, respectively. This substantial impact persists in the medium-run, even as lockdowns are lifted, there is, however, substantial heterogeneity across different types of lockdown measures, different countries, and different sources of pollution. We show that some country trajectories are much more appealing (with fewer COVID-19 casualties, less economic downturn and bigger pollution reductions) than others. Our results have important policy implications and highlight the potential to ‘build back better’ a sustainable economy where pollution can be curbed in a less economically costly way than during the COVID-19 pandemic.

Impact of COVID-19 and intensive care unit capacity on vaccination support: Evidence from a two-leg representative survey in the United Kingdom.

BACKGROUND: Overcoming coronavirus disease (COVID-19) will likely require mass vaccination. With vaccination scepticism rising in many countries, assessing the willingness to vaccinate against COVID-19 is of crucial global health importance. OBJECTIVE: The goal of this study was to examine how personal and family COVID-19 risk and ICU (intensive care unit) availability just before the pandemics influence the acceptance of future COVID-19 vaccines. METHODS: A two-leg survey was carried out for comparing vaccination attitudes pre-and post-COVID-19. UK residents were surveyed in October 2019 about their vaccination attitudes, and again in a follow-up survey in April 2020, containing the previous questions and further ones related to COVID-19 exposure and COVID-19 vaccine attitudes. The study combined survey results with local COVID-19 incidence and pre-COVID-19 measures of ICU capacity and occupancy. Regression analysis of the impact of individual and public health factors on attitudes towards COVID-19 vaccination was performed. RESULTS: The October 2019 survey included a nationally representative sample of 1653 UK residents. All of them were invited for the follow-up survey in April 2020, and 1194 (72%) participated. The April 2020 sample remained nationally representative. Overall, 85% of respondents (and 55% of vaccine sceptics) would be willing to be vaccinated against COVID-19. Higher personal and family risk for COVID-19 was associated with stronger COVID-19 vaccination willingness, whereas low pre-COVID-19 ICU availability was associated with lower trust in medical experts and lower COVID-19 vaccine support. Further, general vaccination support has risen during the COVID-19 pandemic. CONCLUSION: Support for COVID-19 vaccination is high amongst all groups, even vaccine sceptics, boding well for future vaccination take-up rates. Vaccination willingness is correlated with health care availability during the COVID-19 crisis, suggesting a powerful synergy between health care system performance during crisis and the general population's trust in the medical profession - as reflected in vaccination support.

COVID-19 and Conflict: Major Risks and Policy Responses.

The COVID-19 pandemic entails a medium- and long-run risk of heightened political conflict. In this short essay we distinguish four major consequences of COVID-19 that may fuel social tensions and political violence, namely i) spiking poverty, ii) education under stress, iii) potential for repression, and iv) reduced inter-dependence. After discussing them in turn, we will formulate policy recommendations on how to attenuate these risks.
