This paper studies the optimal design of rules in a dynamic model when there is a time inconsistency problem and uncertainty about whether the policy maker can commit to follow the rule ex post. The policy maker can either be a commitment type, which can always commit to follow rules, or an...

Expectations of bailouts by central governments incentivize overborrowing by local governments. In this paper, we ask if fiscal rules can correct these incentives to overborrow when central governments cannot commit and if these rules will arise in equilibrium. We address these questions in a...

Expectations of transfers by central governments incentivize overborrowing by local governments. In this paper, we ask if fiscal rules can reduce overborrowing if central governments cannot commit. We study a model in which the central government's type is unknown and show that fiscal rules...

We study the interaction of incentives to free-ride on information acquisition and strategically delay irreversible investment in environments in which multiple firms evaluate an investment opportunity. In our model, two firms decide how quickly to privately obtain information about the...

The epidemiological literature suggests that virus transmission occurs only when individuals are in relatively close contact. We show that if society can control the extent to which economic agents are exposed to the virus and agents can commit to contracts, virus externalities are local, and...

We develop a simple dynamic economic model of epidemic transmission designed to be consistent with widely used SIR biological models of the transmission of epidemics, while incorporating economic benefits and costs as well. Our main finding is that targeted testing and isolation policies deliver...
