Misinformation is linked to increased social divisions and adverse health outcomes. While most research focuses on the spread of misinformation, we examine the production of misinformation intended to mislead (disinformation). Our field experiment (N=1,200) found, adjusting for circumstantial...

There are widespread concerns that the ongoing COVID-19 pandemic leads to negative attitudes or even stigmatization, especially towards peoples and products from the epicenters. We study the effects of information treatments on partially mitigating the negative impacts such as stigmatization on...

Social distancing helps to prevent the spread of COVlD-19 and other infectious diseases. However, the impact of social distancing on key social behaviors during crises, such as trust, is unclear. We use a priming experiment to investigate whether social distancing impedes or promotes trust. Our...

Lack of information about COVID-19 and its spread may have contributed to excess mortality at the pandemic's onset. In April and May 2020, we implemented a randomized controlled trial with more than 3,000 households in 150 Bangladeshi villages. Our one-to-one information campaign via phone...

We study the stability of noncognitive skills by comparing experimental results gathered before and during the COVID-19 pandemic. Using a sample of professional traders, we find a significant decrease in agreeableness and locus of control and a moderate decrease in grit. These patterns are...

The Covid-19 pandemic has induced worldwide natural experiments on the effects of crowds. We exploit one of these experiments currently taking place over several countries in almost identical settings: professional football matches played behind closed doors. We find large and statistically...

Social pressure may have relevant consequences in many contexts but it is hard to evaluate it empirically. In this paper we exploit a natural experiment in soccer to provide clear evidence of its effects. We aim to study how social pressure from the crowd in a stadium affects both players and...
