We study the propagation of nominal shocks in a dispersed information economy where firms learn from and respond to information generated by their activities in product and factor markets. We show that imperfect information on its own has no effect on equilibrium outcomes, when firms have the...

Why do humans believe in moralizing gods? Leading accounts argue that these beliefs evolved because they help societies grow and promote group cooperation. Yet recent evidence suggests that beliefs in moralizing gods are not limited to large societies and might not have strong effects on...

Does enhanced access to data foster or hinder competition among firms? Using a competition-in-utility framework that encompasses many situations where firms use data, we model data as a revenue-shifter and identify two opposite effects: a mark-up effect according to which data induces firms to...

We study the feasibility and profitability of predation in a dynamic environment, using a parsimonious infinite-horizon, complete information setting in which an incumbent repeatedly faces potential entry. When a rival enters, the incumbent chooses whether to accommodate or predate it; the entrant...

Tipping points define situations where a system experiences sudden and irreversible changes and are generally associated with a random level of the system below which the changes materialize. In this paper, we study a singular stochastic control problem in which the performance criterion depends on...

We study a repeated sender–receiver game where inspections are public but the sender’s action is hidden unless inspected. A detected deception ends the relationship or triggers a finite punishment. We show the public state is low-dimensional and prove existence of a stationary equilibrium with...
