This paper uses a dynamic stochastic general equilibrium model of a two-sector small open economy to analyze how the Maastricht criteria modify a fully credible optimal monetary policy in the Economic and Monetary Union accession countries. We show that if the country is not constrained by the criteria, optimal policy should stabilize fluctuations in PPI inflation, in the aggregate output gap, and in the domestic and international terms of trade. The optimal policy constrained permanently by the Maastricht criteria is characterized by reduced variability of the nominal exchange rate, CPI inflation, and the nominal interest rate and by lower optimal targets for CPI inflation and nominal interest rate. This policy results in higher variability and nonzero means for both PPI inflation and output gap, thus leading to additional, but small, welfare costs compared with the unconstrained policy.

This paper studies monetary policy in models where multiple assets have different liquidity properties: safe and “pseudo-safe” assets coexist. A shock worsening the liquidity properties of the pseudo-safe assets raises interest rate spreads and can cause a deep recession-cum-deflation. Expanding the central bank’s balance sheet fills the shortage of safe assets and counteracts the recession. Lowering the interest rate on reserves insulates market interest rates from the liquidity shock and improves risk sharing between borrowers and savers. (JEL E31, E32, E43, E44, E52)

We use robust control to study how a central bank in an economy with imperfect interest rate pass-through conducts monetary policy if it fears that its model could be misspecified. We find that, first, whether robust optimal monetary policy under commitment responds more cautiously or more aggressively depends crucially on the source of shock. Imperfect pass-through amplifies the robust policy. Second, if the central bank is concerned about uncertainty, it dampens volatility in the inflation rate preemptively but accepts higher volatility in the output gap and loan rate. However, for highly sticky loan rates, insurance against model misspecification becomes particularly pricy. Third, if the central bank fears uncertainty only in the IS equation or the loan rate equation, the robust policy shifts its concern for stabilization away from inflation.

AbstractWe propose a method to assess the efficiency of macroeconomic outcomes using the restrictions implied by optimal policy DSGE models for the volatility of observable variables. The method exploits the variation in the model parameters, rather than random deviations from the optimal policy. In the new Keynesian business cycle model this approach shows that optimal monetary policy imposes tighter restrictions on the behavior of the economy than is readily apparent. The method suggests that for the historical output, inflation and interest rate volatility in the United States over the 1984–2005 period to be generated by any optimal monetary policy with a high probability, the observed interest rate time series should have a 25% larger variance than in the data.

Empirical evidence suggests that the instrument rule describing the interest rate–setting behavior of the Federal Reserve is nonlinear. This paper shows that optimal monetary policy under parameter uncertainty can motivate this pattern. If the central bank is uncertain about the slope of the Phillips curve and follows a min–max strategy to formulate policy, the interest rate reacts more strongly to inflation when inflation is further away from target. The reason is that the worst case the central bank takes into account is endogenous and depends on the inflation rate and the output gap. As inflation increases, the worst-case perception of the Phillips curve slope becomes larger, thus requiring a stronger interest rate adjustment. Empirical evidence supports this form of nonlinearity for post-1982 U.S. data.
