Health and Economic Impact of the COVID-19 Crisis in South Africa and Brazil: Exploring Experiences, Perceptions and Policy Preferences
AbstractThe growing COVID-19 crisis has created an unprecedented health, as well as economic crisis. Following the public health strategies adopted elsewhere, many governments in low- and middle income countries (LMICs) have introduced various levels of “lockdown” to reduce the number of new infections. While these measures can reduce transmission and ‘flatten the curve’ of new cases to protect fragile health systems, they can come at a great economic cost, especially for the more fragile populations. Voices have emerged against lockdowns, claiming that the price to pay is too high. In this project, we use two large online surveys in Brazil and South Africa, two large countries similar in their economic inequalities but different in their policy responses. We explore people’s experiences of the economic and health effects impact of the crisis, elicit beliefs about perceived health and economic risks, as well as perceived benefits and risks associated with different policy responses. Using a survey experiment where respondents are randomized to receiving different messages, we will also test the impact of information on people’s risk perceptions and policy preferences.
Battling the Infodemics: Health Communication Effectiveness During COVID-19
AbstractThe coronavirus disease (COVID-19) outbreak in many parts of the world has triggered serious threats to public health. During this period of crisis, the World Health Organization (WHO) reminded all countries and communities that the spread of this virus could be significantly slowed through the implementation of robust containment and control measures. In light of this, the role of public health bodies in communicating the right message and in the right form to the public seems crucial.
In our study, we aim to assess the effectiveness of communication strategies used by international and national public health authorities to inform the public on COVID-19 risks and prevention. We conducted a survey experiment on nationally representative samples of adults from seven European countries (N=7500) to test the efficacy of public health messages in a form of prevention information provision emphasizing either individual or societal benefit of adherence to such measures. The study seeks to investigate how people’s risk perceptions and behaviors change subject to the preventive information provision as compared to the control group.
The findings of this research will be relevant for policymakers and public health professionals in the development of effective communication strategies during disease outbreaks.
Nudging for Lockdown: Behavioural Insights from an Online Experiment
AbstractA web-based survey -made in April/May 2020 among a representative sample of the French population- combined several incentivized experimental economics' tasks that allowed to precisely measure various behavioural dimensions: risk and time preferences, cooperativeness, trustfulness and pro-sociability (based on SV0). Adherence to barrier gesture and to confinement are documented in the same survey. We also tested, based on RCT design, a social-norm nudge aiming at supporting the confinement device. In this presentation, we are focusing on the nudge-experiment. The effectiveness of the nudge is challenged for the overall sample and for selected subpopulations. The behavioural economic metrics potentially explanatory of behaviours are put in competition in order to identify the one(s) that are most strongly correlated with a positive outcome for the nudge policy. One of the main question is the role of pro-sociability in the magnitude of the impact of the social-norm nudge. This knowledge about the psychological conditions for a nudge to be effective is new. This is a prerequisite to better target communication about future confinement devices.
