Real equipment investment in the United States boomed in the 1990s, led by soaring investment in computers. We find that traditional aggregate econometric models completely fail to capture the magnitude of this growth-mainly because these models neglect to address two features that were crucial...

A number of researchers have recently argued that the new-Keynesian Phillips curve matches the empirical behavior of inflation well when the labor income share is used as a driving variable, but fits poorly when deterministically detrended output is used. The theoretical motivation for these...
