This paper investigates principally the effects of a technological innovation on hours worked in a sticky price model. Our challenge is to reproduce the short-run decline in employment supported by a large range of recent works, inspired by Gali (1999), regardless of any monetary policy...

In this paper, we ask whether a small structural model with sticky prices and wages, embedding various modelling devices designed to increase the degree of strategic complementarity between price-setters, can fit postwar US data. To answer this question, we resort to a two-step empirical...

This paper shows that there are striking implications that stem from including durable goods in otherwise conventional sticky price models. The behavior of these models depends heavily on whether durable goods are present and whether these goods have sticky prices. If long-lived durables have...

This paper studies the role of unemployment insurance in a sticky-price model that features an efficiency-wage view of the labor market based on unobservable effort. The risk-sharing mechanism central to the model permits, but does not force, agents to be fully insured. Structural parameters are...

This paper compares the welfare effects of anticipated and unanticipated cost-push shocks in the canonical New Keynesian model with optimal monetary policy. We find that, for empirically plausible degrees of nominal rigidity, the anticipation of a future cost-push shock leads to a higher welfare...

Factor models of disaggregate inflation indices suggest that sectoral shocks generate the bulk of sectoral inflation variance, but no persistence. Aggregate shocks, by contrast, are the root of sectoral inflation persistence, but have negligible relative variance. We show that simple factor...

New-Keynesian (NK) models can only account for the dynamic effects of monetary policy shocks if it is assumed that aggregate capital accumulation is much smoother than it would be the case under frictionless firm-level investment, as discussed in Woodford (2003, Ch. 5). We find that lumpy...

The research led by Gali (AER 1999) and Basu, Fernald, and Kimball (AER 2006) raises two important questions regarding the validity of the RBC theory: (i) How important are technology shocks in explaining the business cycle? (ii) Do impulse responses to technology shocks found in the data reject...

This paper investigates wage dynamics assuming the potential presence of dual wage stickiness: with respect to both the frequency as well as the size of wage adjustments. In particular, this paper proposes a structural model of wage inflation dynamics assuming that although workers adjust wage...
