We reformulate the Smets-Wouters (2007) framework by embedding the theory of unemployment proposed in Galí (2011a,b). We estimate the resulting model using postwar U.S. data, while treating the unemployment rate as an additional observable variable. Our approach overcomes the lack of...

Several recent studies imply that the response of national saving to fiscal policy is non-monotonic. In this paper, we use two data sets to search for the circumstances in which such non-monotonic responses arise: one refers to a sample of OECD countries, as in previous studies, and one to a...

Recent cross-country studies on the globalization and output-inflation tradeoff correlation find openness has no significant effect on OECD countries. Those studies assume parameter constancy across countries. In this paper, we argue that this assumption does not hold for major industrialized...

Nominal price and wage rigidity renders monetary policy effective over output. However, this effectiveness extends, under widely used overlapping-wage and Calvo-contract Phillips Curves, to planned monetary policy (‘exploitability’) and not merely to policy surprises. We argue that within...

The New Keynesian Phillips curve explains inflation dynamics as being driven by current and expected future real marginal costs. In competitive labour markets, the labour share can serve as a proxy for the latter. In this paper, we study the role of real marginal cost components implied by...

We examine the effect of introducing price stickiness into a stochastic growth model subject to a cash in advance constraint. As has been previously documented, the introduction of price rigidities provides a substantial source of monetary non-neutrality; leads to a strong positive correlation...

The Calvo contract Phillips Curve is widely indexed for general inflation, using either core inflation or other backward-looking formulae. Such a Phillips Curve implies a high and persistent degree of nominal rigidity. It is argued here that optimal indexation would by contrast use the rational...

We study optimal price setting by a monopolist in an infinite horizon model with stochastic costs, moderate inflation, and costly price adjustment. For realistic parameters, chosen to replicate observed frequencies of price changes, the model fits numerically several empirical regularities. In...

This article is related to the large recent literature on Phillips curves in sticky- price equilibrium models. It differs in allowing for the degree of price stickiness to be determined endogenously. A closed-form solution for short-term inflation is derived from the dynamic stochastic general...

This article complements the structural New-Keynesian macro framework with a no-arbitrage affine term structure model. Whereas our methodology is general, we focus on an extended macro-model with unobservable processes for the inflation target and the natural rate of output which are filtered...
