We model welfare-maximizing policy in an infinite-horizon setting when the probability of a tipping point, the welfare change due to a tipping point, and knowledge about a tipping point's trigger all depend on the policy path. Analytic results demonstrate how optimal policy depends on the...

Continuous time is a superior representation of both the economic and climate systems that Integrated Assessment Models (IAM) aim to study. Moreover, continuous-time representations are simple to express. Continuous-time models are usually solved by discretizing time, but the quality of a...

This paper characterizes a robust optimal policy rule in a simple forward-looking model, when the policymaker faces uncertainty about model parameters and shock processes. We show that the robust optimal policy rule is likely to involve a stronger response of the interest rate to fluctuations in...

We propose a model of bounded rationality based on time-costs of deliberating current and future decisions. We model an individual decision maker%u2019s thinking process as a thought-experiment that takes time and let the decision maker %u201Cthink ahead%u201D about future decision problems in...

We propose a model of equilibrium contracting between two agents who are "boundedly rational" in the sense that they face time-costs of deliberating current and future transactions. We show that equilibrium contracts may be incomplete and assign control rights: they may leave some enforceable...

Time-inconsistency of no-bailout policies can create incentives for banks to take excessive risks and generate endogenous crises when the government cannot commit. However, at the outbreak of financial problems, usually the government is uncertain about their nature, and hence it may delay...

A manager's shareholders, board of directors, and potential future employers are continually assessing his ability. A rich literature has documented that this insight has profound implications for corporate governance because assessment generates incentives (good and bad), introduces assorted...

This paper investigates consumer switching costs in the context of health insurance markets, where adverse selection is a potential concern. Though previous work has studied these phenomena in isolation, they interact in a way that directly impacts market outcomes and consumer welfare. Our...

We introduce an algorithm for solving dynamic economic models that merges stochastic simulation and projection approaches: we use simulation to approximate the ergodic measure of the solution, we construct a fixed grid covering the support of the constructed ergodic measure, and we use...

Linear RE models typically possess a multiplicity of solutions. Consider, however, the requirement that the solution coefficients must not be infinitely discontinuous in the model's structural parameters. In particular, we require that the solutions should be continuous in the limit as those...
