Policy Rules and Large Crises in Emerging Markets
Emerging countries have increasingly adopted rules to discipline government policy. The COVID-19 shock lead to widespread suspension and modification of these rules. We study rules and flexibility in a sovereign default model with domestic fiscal and monetary policies and long-term external debt. We find welfare gains from adopting monetary targets and debt limits during normal times. Though government policy cannot itself counteract fundamental shocks hitting the economy, the adoption of rules has a significant impact on policy, macroeconomic outcomes and welfare during large, unexpected ...

Optimal Time-Consistent Taxation with Default
We study optimal time-consistent distortionary taxation when the repayment of government debt is not enforceable. The government taxes labor income or issues noncontingent debt in order to finance an exogenous stream of stochastic government expenditures. The government can repudiate its debt subject to some default costs, thereby introducing some state-contingency to debt. We are motivated by the fact that domestic sovereign default is an empirically relevant phenomenon, as Reinhart and Rogoff (2011) demonstrated. Optimal policy is characterized by two opposing incentives: an incentive to ...

Very Simple Markov-Perfect Industry Dynamics
This paper develops an econometric model of industry dynamics for concentrated markets that can be estimated very quickly from market-level panel data on the number of producers and consumers using a nested fixed-point algorithm. We show that the model has an essentially unique symmetric Markov-perfect equilibrium that can be calculated from the fixed points of a finite sequence of low-dimensional contraction mappings. Our nested fixed point procedure extends Rust's (1987) to account for the observable implications of mixed strategies on survival. We illustrate the model's empirical ...

Speed Limit Policy and Liquidity Traps
The zero lower bound (ZLB) constraint on interest rates makes speed limit policies (SLPs)---policies aimed at stabilizing the output growth---less effective. Away from the ZLB, the history dependence induced by a concern for output growth stabilization improves the inflation-output tradeoff for a discretionary central bank. However, in the aftermath of a deep recession with a binding ZLB, a central bank with an objective for output growth stabilization aims to engineer a more gradual increase in output than under the standard discretionary policy. The anticipation of a more restrained ...

Markov-Perfect Risk Sharing, Moral Hazard and Limited Commitment
We define, characterize and compute Markov-perfect risk-sharing contracts in a dynamic stochastic economy with endogenous asset accumulation and simultaneous limited commitment and moral hazard frictions. We prove that Markov-perfect insurance contracts preserve standard properties of optimal insurance with private information and are not more restrictive than a long-term contract with one-sided commitment. Markov-perfect contracts imply a determinate asset time-path and a non-degenerate long-run stationary wealth distribution. We show numerically that Markov-perfect contracts provide sizably ...

Policy Rules and Large Crises in Emerging Markets
Emerging economies have adopted fiscal and monetary rules to discipline government policy. We study the value and macroeconomic implications of rules and flexibility within a sovereign-default model that incorporates domestic fiscal and monetary policies and long-term external debt. Adopting monetary targets and debt limits during normal times yields welfare gains. Suspending rules can significantly influence policy, macroeconomic outcomes, and welfare during large, unforeseen crises. The gains from flexibility depend on how quickly policymakers are able to reimpose rules after the crisis.
