Estimating peer effects is notoriously difficult because of the reflection problem and the endogeneity of peer group formation. This paper tests for peer effects in obesity in a novel way that addresses these challenges. It addresses the reflection problem by using the alter's genetic risk score...

We use temperature variation within narrowly-defined geographic and demographic cells to show that exposure to extreme heat increases the risk of maternal hospitalization during pregnancy for potentially life-threatening causes. We find that this effect is driven by women residing in...

The educational attainment of siblings is highly correlated. We test for a specific type of peer effect between siblings in educational attainment: genetic nurture. Specifically, we test whether a person’s educational attainment is correlated with their sibling’s polygenic score (PGS) for...

We study the effect of decentralization on the access to some poverty-related public services in Benin. Compiling panel data from local governments' accounts and from surveys on 18,000 Beninese households performed in 2006 and 2007, our study suggests that decentralization has a positive overall...

Decentralization has been put forward as a powerful tool to reduce poverty and improve governance in Africa. The aim of this paper is to study the existence, and identify the nature, of spillovers resulting from local expenditure policies. These spillovers impact the efficiency of...

Using original data from two waves of a survey conducted in March and April 2020 in eight OECD countries (N = 21,649), we show that women are more likely to see COVID-19 as a very serious health problem, to agree with restraining public policy measures adopted in response to it, and to comply...

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...

Beyond its immediate impact on public health and the economy, the COVID-19 pandemic has put democracy under stress. While a common view is that people should blame the government rather than the political system for bad crisis management, an opposing view is that dissatisfaction with government...
