Passive behavior is ubiquitous - even when facing various alternatives to choose from, people commonly fail to take decisions. This paper provides evidence on the cognitive foundations of such "passive choices" and studies implications for policies that encourage active decision-making. In an...

We study the effects of two widely observed behavioral policy interventions⸻the simplification of complex decisions and the implementation of high-quality defaults. Based on a laboratory experiment featuring a dual-task paradigm, we demonstrate that these policies do not only improve decisions...

Policymakers discuss nudges as instruments to foster individual public good contributions. Contrary to the original aim of nudges, which is to improve decision outcomes for the individual, pro-social nudges aim to improve the social outcomes of individual behavior. This can potentially result in...

We test whether and, if so, how incentives to promote pro-social behavior affect the extent to which it spills over to subsequent charitable giving. To do so we conduct a two-period artefactual field experiment to study repeated donation decisions of more than 700 participants. We vary how...

Carbon taxes are a prominent policy instrument for decreasing the consumption of CO2-intensive goods in order to reduce the negative external effects involved in the production or consumption of such goods. A tax leads to higher consumer prices, which typically lowers consumption. However, in...

Bilateral gift exchange often benefits the gift-giver, but what is the effect of multilateral gift exchange? This study employs a two-giver-one-recipient real task gift exchange game to investigate the effect of gift competition. We show that gift competition hurts givers and benefits...

We study cheating as a collective-risk social dilemma in a group setting in which individuals are asked to report their actual outcomes. Misreporting their outcomes increases the individual's earnings but when the sum of claims in the group reaches a certain threshold, a risk of collective...

Does political polarization lead to dysfunctional behavior? To study this question, we investigate the attitudes of supporters of Donald Trump and of Hillary Clinton towards each other and how these attitudes affect spiteful behavior. We find that both Trump and Clinton supporters display less...
