We show that there is a unique correlated equilibrium, identical to the unique Nash equilibrium, in the classic Bertrand oligopoly model with homogenous goods. This provides a theoretical underpinning for the so-called "Bertrand paradox" and also generalizes earlier results on mixed-strategy...

We study a monopoly insurance model with endogenous information acquisition. Through a continuous effort choice, consumers can determine the precision of a privately observed signal that is informative about their accident risk. The equilibrium effort is, depending on parameter values, either...

This paper examines how a firm can strategically use sellouts to influence beliefs about its good's popularity. A monopolist faces a market of conformist consumers, whose willingness to pay is increasing in their beliefs about aggregate demand. Consumers are broadly rational but have limited...

This study investigates the structure of optimal incentives in a stochastic environment and provides evidence for the use of self-enforcing relational contracts. We show theoretically that under relational contracting, firms can credibly promise chief executive officers (CEOs) larger bonuses in...

Free riding problems can be more severe in multiple-person social dilemmas than in two-person dilemmas, since agents can hide their actions behind the veil of anonymity. In this paper, we use field data on waste sorting to study the effect of visibility in social dilemmas. We compare the sorting...

This paper exploits microdata from parish registers in a rural Tuscan village to trace the relationship between experienced and expected child mortality on household fertility strategies. It turns out that spacing of births and hence completed fertility are not only linked to economic risks and...

What are the welfare effects of a policy that facilitates for insurance customers to privately and covertly learn about their accident risks? We endogenize the information structure in Stiglitz's classic monopoly insurance model. We first show that his results are robust: For a small information...

Asset prices tend to undergo wide swings around long-run equilibrium values which can have detrimental effects on the real economy. To get a better understanding of how the fi?nancial sector and the real economy interact this paper models the long swings in the Swiss franc-US dollar foreign...

We investigate experimentally the effects of corrupt experts on information aggregation in committees. We find that non-experts are significantly less likely to delegate through abstention when there is a probability that experts are corrupt. Such decreased abstention, when the probability of...

In a laboratory experiment designed to capture key aspects of the interaction between physicians and patients in a stylized way, we study the effects of medical insurance and competition in the guise of free choice of physician. Medical treatment is an example of a credence good: only the...
