We use a microfounded dynamic stochastic general equilibrium (DSGE) model with banks to study interactions between monetary and macroprudential policies in a small open economy. The model is calibrated/estimated for Korea. Cooperation of monetary and macroprudential policies is optimal under a...

We use a dynamic game model of a two-country monetary union to study the impacts of an exogenous fall in aggregate demand, the resulting increase in public debt, and the consequences of a sovereign debt haircut for a member country or bloc of the union. In this union, the governments of...

We estimate the low-frequency relationship between fiscal deficits and inflation and pay special attention to its potential time variation by estimating a time-varying VAR model for U.S. data from 1900 to 2011. We find the strongest relationship neither in times of crisis nor in times of high...

This paper develops a parsimonious model of individual exposure and of public health policy that can be used to study the evolution of an epidemic and the optimal use of lockdown policies and other non-pharmaceutical interventions. At the heart of individual exposure choices are the trade-offs...

Modifying the mandate of a discretionary central bank to include an interest-rate smoothing objective increases the welfare of an economy where large contractionary shocks occasionally force the central bank to lower the policy rate to its effective lower bound. The central bank with an...

Against the backdrop of elevated model uncertainty in DSGE models with a detailed modeling of financial intermediaries, we investigate the performance of optimized macroprudential policy rules within and across models. Using three canonical banking DSGE models as a representative sample, we show...

This paper explicitly models strategic interaction between two independent national fiscal authorities and a single central bank in a simple New Keynesian model of a monetary union. Monetary policy is constrained by the zero lower bound on nominal interest rates. Coordination of fiscal policies...

The paper examines the stabilizing properties of fiscal policy for current account imbalances under alternative exchange rate regimes. Using a small open economy DSGE model with fiscal feedback rules, we investigate the dynamic responses of different shocks to macroeconomic variables and their...
