Monetary Policy, Employment Shortfalls, and the Natural Rate Hypothesis
Activity shortfalls are more costly than strong activity. I consider optimal monetary policy under discretion with an asymmetric (activity shortfalls) loss function. The model satisfies the natural rate hypothesis. The asymmetric loss function and resulting optimal monetary policy exacerbates shortfalls in activity. The additional frequency of activity shortfalls arises from the adjustment of expectations implied by the natural rate hypothesis. The shortfalls asymmetry leads to an inflationary bias, similar to results in the time-consistency literature. Mandating a central bank objective with ...

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.

Drifting Inflation Targets and Monetary Stagflation
This paper revisits the phenomenon of stagflation. Using a standard New Keynesian dynamic, stochastic general equilibrium model, we show that stagflation from monetary policy alone is a very common occurrence when the economy is subject to both deviations from the policy rule and a drifting inflation target. Once the inflation target is fixed, the incidence of stagflation in the baseline model is essentially eliminated. In contrast with several other recent papers that have focused on the connection between monetary policy and stagflation, we show that while high uncertainty about monetary ...

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 ...
