This paper addresses the effectiveness of fiscal policy at zero nominal interest rates. I analyze a stochastic general equilibrium model with sticky prices and rational expectations and assume that the government cannot commit to future policy. Real government spending increases demand by...

This paper evaluates the consequences of the integration of international asset markets when goods markets are characterized by price rigidities. Using an open economy general equilibrium model with volatility in the money markets, we show that such an integration is not universally beneficial....

We construct a price index with weights for the prices of different PCE (personal consumption expenditures) goods chosen to minimize the welfare costs of nominal distortions. In this cost-of-nominal-distortions index (CONDI), the weights are computed in a multi-sector New Keynesian model with...

We derive aggregate supply (AS) relationships for an intermediate-run macro model. The wage-price spiral provides the conceptual framework for a synthesis of different contesting theoretical and empirical perspectives on the AS curve: the Phillips curve model (PCM) and the wage-price equilibrium...

Using a large panel of quarterly firm survey data from 1984 to 2007, which allow changes in firms' prices to be linked to several firm-specific variables, this paper finds that state-dependent pricing is clearly important in a low inflation environment and that variables measuring the current...

This paper sets up a canonical new Keynesian small open economy model with nominal price rigidities to explore the impact of habit persistence and exchange rate pass-through on the welfare ranking of alternative monetary policy rules. It identifies three factors that can affect the welfare...

Empirical data show that firms tend to improve their ranking in the productivity distribution over time. A stickyprice model with firm-level productivity growth fits this data and predicts that the optimal long-run inflation rate is positive and between 1.5% and 2% per year. In contrast, the...

The real effects of an imperfectly credible disinflation depend critically on the extent of price rigidity. In this paper, we examine how credibility affects the outcome of a disinflation in a model with endogenous time-dependent pricing rules. Both the endogenous initial degree of price...

It has been widely argued that inflation persistence since WWII has been widespread and durable and that it can only be accounted for by models with a high degree of nominal rigidity. We examine UK post-war data where after confirming previous studies findings of varying persistence due to...

This paper argues that the cross-sectional approach to durations is essential to understand nominal rigidity because this captures the fact that price-spells are generated by firms' price-setting behavior. Since the distribution of durations is dominated by a proliferation of short contracts,...
