We study the environmental and economic effects of public abatement in the presence of multiple stable steady-state ecological equilibria. Under shallow-lake dynamics (SLD), the isocline for the stock of pollution features two stable branches, a good and a bad one. Assuming that the ecology is...

This paper analyzes an early modern German economy to test alternative theories about guilds. It finds little evidence to support recent hypotheses arguing that guilds corrected market failures relating to product quality, training, and innovation. But it finds that guilds were social networks...

We investigate the relationship between social capital and the decision to flee after a fatal road accident. This event is unplanned, and the decision is taken under great emotional distress and time pressure, thus providing a test of whether social capital matters for behaviour in extreme...

How should we evaluate the welfare implications of improvements to safety technologies in the presence of offsetting behavior? We model this problem as a symmetric game in which each player's payoff depends on his own action and the average action of the other players, and analyze under which...

This paper studies how society votes on the payroll taxes of a basic income and a social health insurance scheme. Individuals differ along the two most important dimensions when it comes to the design of the two welfare schemes, namely, income and risk. Even though the introduction of a basic...

We describe a dynamic model of costly information sharing, where private information affecting collective-value actions is transmitted by social proximity. Individuals make voluntary contributions towards the provision of a pure public good, and information transmission about quality of...

We examine the formation of multilateral, hub-and-spoke and bilateral international R&D strategic alliances (overlapping climate clubs) to reduce CO2 emissions. R&D provision in clubs produces two types of positive externalities: a global public good (i.e., reduction of CO2 emissions) and...

We characterize a measure of social welfare for linear production economies in which individuals differ in productive skills and preferences. The key feature of our measure is that it aggregates fairness gaps, defined as the difference between the money-metric utility that the individual...

Does the Internet undermine social capital or facilitate inter-personal and civic engagement in the real world? Merging unique telecommunication data with geo-coded German individuallevel data, we investigate how broadband Internet affects several dimensions of social capital. One identification...

Standard economics omits the role of narratives (the stories that people tell themselves and others) when they make all kinds of decisions. Narratives play a role in understanding the environment; focusing attention; predicting events; motivating action; assigning social roles and identities;...
