This paper estimates the effects of early interventions in the Swedish sickness insurance system. The aim of the interventions is to screen and, further to, rehabilitate sick listed individuals. We find that the early interventions - in contrast to what is expected - increase the inflow into...

There is a longstanding concern that material incentives might undermine prosocial motivation, leading to a decrease in blood donations rather than an increase. This paper provides an empirical test of how material incentives affect blood donations in a large-scale field experiment spanning...

In this paper, we propose a decision framework where people are individually asked to either actively consent to or dissent from some pro-social behavior. We hypothesize that confronting individuals with the choice of whether to engage in a specific pro-social behavior contributes to the...

We combine information on social networks with medical records and survey data in order to examine how friends affect one's decision to get vaccinated against the flu. The random assignment of undergraduates to residential halls at a large private university allows us to estimate how peer...

Maintaining high standards of care from doctors, nurses and other health professionals is of critical importance for an effective and efficient health system. Yet deficient levels of health worker performance, including low effort, absenteeism, and lack of compliance with clinical guidelines,...

We conduct a field experiment to assess whether alcohol-induced behavioural changes explain participants' recent history of violence. We find that being in a drinking environment, rather than intoxication, reduces participants' cognitive ability but increases their overconfidence. Those who...

Beliefs about collective outcomes, such as economic growth or firm profitability, play an important role in many contexts. We study biases in the formation of such beliefs. Specifically, we explore whether over-optimism and self-serving biases in information processing-documented for beliefs...

Long-term follow-up of early childhood health interventions is important for human capital accumulation. We provide experimental evidence on child health and human capital outcomes from the longer-term follow-up of a school-based nutrition intervention in India. Using panel data, we examine the...
