Using data from a large-scale randomized controlled trial conducted in Danish job centers, this paper investigates the effects of an intensification of mandatory return-to-work activities on the subsequent labor market outcomes for sick-listed workers. Using variations in local treatment...

This study uses a simple theory model to examine how time preferences influence food choices made by individuals, which in turn have implications for their future health. The theory results demonstrate that individuals with higher bias for the present or lower patience will have poorer health...

To test for ethnic discrimination in access to outpatient health care services, we carry out an email-correspondence study in Germany. We approach 3,224 physician offices in the 79 largest cities in Germany with fictitious appointment requests and randomized patients' characteristics. We find...

We implement a mixed method approach that combines a randomized controlled trial and qualitative data collection to assess whether, and if so how, behavioural change can be sustained. We do so in the context of Pakistan's national sanitation strategy to combat open defecation, Community-Led...

Peoples’ willingness to vaccinate is critical to combating the COVID-19 pandemic. We devise a representative experiment to study how the design of the vaccine approval procedure affects public attitudes towards vaccination. Compared to an Emergency Use Authorization, choosing the more thorough...

Alcohol has long been known as the demon drink; an epithet owed to numerous social ills associated with it. Our lab-in-the-field experiment assesses the extent to which intoxication leads to changes in overconfidence or cognitive ability that are often linked to problematic behaviours. Results...

We find a strong relationship between risk-loving preferences and cognitive ability which becomes stronger as adherence to the generalized axiom of revealed preference (a proxy for rationality) increases. Our results are taken from a field study of individuals at the very bottom of the income...

While the burden of non-communicable diseases is rising in low- and middle-income countries, the uptake of screening for these diseases remains low. We conducted a community-based RCT in Indonesia to assess whether personalized and targeted text messages can increase the demand for existing...

In this study, we use random assignment of vignettes that feature optimistic and pessimistic scenarios with respect to vaccine safety and efficacy on a sample of roughly 1,600 Russians in order to gauge public support for anti-pandemic measures under various scenarios. Negative information on...

There is a longstanding concern that material rewards might undermine pro-social motivations, thereby leading to a decrease in blood donations. This paper provides an empirical test of how material rewards affect blood donations in a three-month large-scale field experiment and a fifteen-month...
