We analyze efficient risk-sharing arrangements when coalitions may deviate. Coalitions form to insure against idiosyncratic income risk. Self-enforcing contracts for both the original coalition and any deviating coalition rely on a belief in future cooperation which we term \social capital". We...

German history over the past 125 years has been turbulent. Marked by two world wars, revolutions and major regime changes, as well as a hyperinflation and three currency reforms, expropriations and territorial divisions, it provides unique insights into the role of country-specific shocks in...

This paper assesses the ability of hiring subsidies to stimulate employment. I build a New Keynesian model with equilibrium unemployment and incomplete markets. Quantitatively, I find that an increase in hiring subsidies reduces unemployment more at the zero lower bound than it does during...

Dissent plays an important role in any society, but dissenters are often silenced through social sanctions. Beyond their persuasive effects, rationales providing arguments supporting dissenters' causes can increase the public expression of dissent by providing a "social cover" for voicing...

Western powers have discussed and implemented several policies in response to the full scale Russian invasion of Ukraine in February 2022. One such possible answer was an immediate embargo on all Russian energy exports to the EU. While seen as a strong measure against Russia's war effort, some...

Overconfidence is one of the most ubiquitous cognitive bias. There is copious evidence of overconfidence being relevant in a diverse set of economic domains. In this paper, we relate the recent concept of cognitive uncertainty with overconfidence. Cognitive uncertainty represents a decision...

We explore the role of social capital in the spread of the recent Covid-19 pandemic in independent analyses for Austria, Germany, Italy, the Netherlands, Sweden, Switzerland and the UK. We exploit within-country variation in social capital and Covid-19 cases to show that high-social-capital...

Do emotional responses to the spread of an infectious disease affect the quality of economic decision-making? In the context of an episode of heightened public concern about Ebola in the US in October 2014, I document that worrying about the possibility of an epidemic can impair cognitive...

In a large-scale online experiment with U.S. Democrats, we examine how the demand for a newsletter about an economic relief plan changes when the newsletter content is fact-checked. We first document an overall muted demand for factchecking when the newsletter features stories from an...

We conduct laboratory experiments to investigate basic predictions of principal-agent theory about the choice of piece rate contracts in the presence of output risk, and provide novel insights that reference dependent preferences affect the tradeoff between risk and incentives. Subjects in our...
