Information Acquisition and the Timing of Actions (Online Appendix)


This paper develops a dynamic model of information acquisition, in which the decision maker lacks control over the timing of their action. It characterizes the optimal dynamic experiment when the decision maker can flexibly choose all relevant aspects of the information they acquire. The decision maker is constrained in the quantity of information an experiment can generate over any time interval. At the optimum, the decision maker concentrates resources in generating a single piece of breakthrough evidence, contradicting their plan of action. Moreover, this is accomplished in a way so that in the absence of such evidence, the decision maker becomes more confident in their intentions. Over time, this leads them to sacrifice the frequency with which breakthroughs occur in order to increase their impact on choice behaviour.

Smart Contracts and the Coase Conjecture, with Thomas Brzustowski and Balázs Szentes (Online Appendix)


This paper reconsiders the problem of a durable-good monopolist who cannot make intertemporal commitments. The buyer’s valuation is binary and his private information. The seller has access to dynamic contracts and, in each period, decides whether deploy the previous period’s contract or to replace it with a new one. Our main result is that the Coase Conjecture fails: the monopolist’s payoff is bounded away from the low valuation irrespective of the discount factor.

Bank Resolution and the Disciplining Effect of Demandable Debt, with Maximilian Guennewig


In a model with asymmetric information on asset returns, banks issue demandable debt if the government's preferred resolution strategy takes the form of bail-ins. Creditors then respond to news on bank fundamentals and subsequent runs on loss-absorbing debt render bail-ins ineffective. Controlling the maturity structure of debt has two benefits. First, longer maturity debt disciplines markets ex-post while avoiding government bailouts. Second, ex-ante market discipline, measured by the average quality of projects, increases. The model provides an explanation why regulators impose minimum maturity requirements for bail-in debt and a motivation to treat short-term debt preferentially during intervention.

The Evolution of Asymmetric Risk Preferences in Dynamic Competitions


This paper analyzes a dynamic competition in which two players gamble independently, and fairly to affect their wealths. At each instant in time, a prize is allocated to the player with the highest wealth. There is a unique equilibrium in which the player lagging in wealth takes maximal risks, while the leading player takes no risks at all. An evolutionary interpretation of the result is offered, which provides a foundation for reference-dependent, asymmetric risk preferences. In particular, when fitness is determined by such dynamic competitions, S-shaped Bernoulli utility functions emerge uniquely.
