This paper explores empirically the role of noisy information in cyclical developments and aims at separating fluctuations that are due to genuine changes in fundamentals from those due to temporary animal spirits or expectational errors (noise shocks). Exploiting the fact that the...

This paper examines the effects of expansionary technology shocks (shocks that increase labor productivity and factor inputs) as opposed to contractionary technology shocks (shocks that increase labor productivity, but decrease factor inputs). We estimate these two shocks jointly based on a...

This paper argues that factor demand linkages can be important for the transmission of both sectoral and aggregate shocks. We show this using a panel of highly disaggregated manufacturing sectors together with sectoral structural VARs. When sectoral interactions are explicitly accounted for, a...

Gali (1999) used a VAR with productivity and hours worked to argue that technology shocks are negatively correlated with labor and are unimportant for the business cycle. More recently, Beaudry and Portier (2003) studied a VAR in productivity and stock prices. Remarkably, they found that the...

Recent empirical work using structural VARs with long-run restrictions assesses whether hours worked per capita rises or falls following a technology improvement. This literature reaches divergent conclusions on the sign of this effect, depending on whether hours worked enters the VAR in...

In this paper the time series properties of the outcomes of two different specifications of a nonparametric productivity analysis are compared using data for three- and four- digit U.S. manufacturing industries over the period 1958-96. The first model is standard and does not account for...

We derive a measure of technological change using firm-level panel data and controlling for imperfect competition, increasing returns and unobserved factor utilization. We show that the latter variable accounts for a relevant portion of the cyclicality of the Solow residual. Our key finding is...

This paper discusses the paper The Source of Historical Economic Fluctuations: An Analysis using Long-Run Restrictions by Neville Francis and Valerie A. Ramey. It argues that these authors have made great progress both in the precise measurement of labor input as well as determining the effect...
