June 2020Socio-Demographic Factors Associated with Self-Protecting Behavior during the Covid-19 Pandemic
with Nicholas W. Papageorge, Matthew V. Zahn, Michèle Belot, Eline van den Broek-Altenburg, Julian C. Jamison, Egon Tripodi: w27378
Disease spread is in part a function of individual behavior. We examine the factors predicting individual behavior during the Covid-19 pandemic in the United States using novel data collected by Belot et al. (2020). Among other factors, we show that people with lower income, less flexible work arrangements (e.g., an inability to tele-work) and lack of outside space at home are less likely to engage in behaviors, such as social distancing, that limit the spread of disease. We also find evidence that region, gender and beliefs predict behavior. Broadly, our findings align with typical relationships between health and socio-economic status. Moreover, they suggest that the burden of measures designed to stem the pandemic are unevenly distributed across socio-demographic groups in ways that aff...
February 2011Who Is (More) Rational?
with Shachar Kariv, Wieland Müller, Dan Silverman: w16791
Revealed preference theory offers a criterion for decision-making quality: if decisions are high quality then there exists a utility function that the choices maximize. We conduct a large-scale field experiment that enables us to test subjects' choices for consistency with utility maximization and to combine the experimental data with a wide range of individual socioeconomic information for the subjects. There is considerable heterogeneity in subjects' consistency scores: high-income and high-education subjects display greater levels of consistency than low-income and low-education subjects, men are more consistent than women, and young subjects are more consistent than older subjects. We also find that consistency with utility maximization is strongly related to wealth: a standard deviati...
