Dynamic stochastic general equilibrium (DSGE) models with nominal rigidities have become a popular tool for monetary policy analysis in recent years. The basic sticky price model has been enriched to include additional sources of nominal and real rigidities. These additional elements have been introduced ...

Our previous work develops methods to study optimal policy in Markov jump-linear-quadratic (MJLQ) models with forward-looking variables: models with conditionally linear dynamics and conditionally quadratic preferences, where the matrices in both preferences and dynamics are random (Svensson and ...

One of the most popular pieces of wisdom in economic policy is the idea that fiscal policy is more effective in a fixed exchange rate regime or a currency union than in a flexible exchange rate regime. In this paper we revisit the theoretical foundations of the conventional wisdom on the relative ...

Increased volatility in the world prices of commodities such as oil and food which are basic imports for many countries has rekindled interest on the question of how monetary policy should best adjust to external commodity price movements. Recent studies have analyzed the issue in the New Keynesian ...

This paper is about an economy in a liquidity trap that is an environment with a zero nominal interest rate deflationary pressures and subpar growth. The paper shows two fiscal policy multipliers in a relatively standard New Keynesian liquidity trap economy with taxation costs. It computes real ...

Developing a better understanding of the costs of disinflation has long been an important objective for macroeconomic research. Since the 1980s, disinflation episodes and strategies have been studied extensively under the assumption of rational expectations. This assumption implies that central bank ...
