The theoretical literature on business cycles predicts a positive investment response to productivity improvements, a prediction we question from theoretical and empirical perspectives. We show that a short-term negative response of investment to a positive technology shock is consistent with a...

This paper examines the importance of productivity shocks in accounting for salient features of U.S. economic developments during the second half of the 1990s, including the surge in investment spending, the substantial deterioration of the trade balance, and the modest decline in inflation. We...

In a New Keynesian model, technology and cost-push shocks compete as terms that stochastically shift the Phillips curve. A version of this model, estimated via maximum likelihood, points to the cost-push shock as far more important than the technology shock in explaining the behavior of output,...

Recently, Gali and others find that technological progress may be contractionary: a favorable technology shock reduces hours worked in the short run. We ask whether this observation is robust in disaggregate data. According to our VAR analysis of 458 four-digit U.S. manufacturing industries for...

This paper uses the neoclassical growth model to identify the effects of technological change on the US business cycle. In the model there are two sources of technological change: neutral, which affects the production of all goods homogeneously, and investment-specific. Investment-specific...
