The Multiplicative Ergodic Theorem provides a novel general methodology to analyze rational expectations models with stochastically varying coefficients. The approach is applied for the first time to economics and analyzes the canonical New Keynesian model with a Taylor rule which switches...

Taylor rules posit a linear relationship between the output gap, inflation, and short-term nominal interest rates. Previous work has shown that the relationship between these key economic variables as captured by the Taylor rule is quite robust both across countries and monetary policy regimes....

Under a flexible inflation targeting regime, should policymakers avoid any reaction to movements in the foreign exchange market? Using data for six advanced open economies explicitly targeting inflation, the paper examines empirically whether real exchange rate disequilibria systematically...

This investigation aims to explain and quantify the deviations of the Taylor Rule. A novel three-step econometric procedure designed to reflect the data-rich environment in which central banks operate is proposed using information for 229 macroeconomic series. This procedure can be applied to...

We examine the conduct of monetary policy in a world where the supply of outside money is controlled by the fiscal authority-a scenario increasingly relevant for many developed economies today. Central bank control over the long-run inflation rate depends on whether fiscal policy is Ricardian or...

This paper considers a two-period monetary double auction with incomplete markets of securities and derivatives. Players may share heterogenous beliefs. Short positions in derivatives are constrained by collateral requirements. A central Bank stands ready to lend money or engage in...

We empirically test the effects of anticipated and unanticipated monetary policy shocks on the growth rate of real industrial production and explicitly test for different types of asymmetries in monetary policy implementation for two major international economies, the U.S. and Brazil. We depart...

We use simulations of the Federal Reserve's FRB/US model to examine the efficacy of a number of proposals for reducing the consequences of the zero bound on nominal interest rates. Among the proposals are: a more aggressive monetary policy; promises to make up any shortfall in monetary ease...

A growing body of evidence finds that policy reaction functions vary substantially over different periods in the United States. This paper explores how moving to an environment in which monetary and fiscal regimes evolve according to a Markov process can change the impacts of policy shocks. In...
