Available in PDF, EPUB and Kindle. Book excerpt: IST shocks are often interpreted as multi-factor productivity (MFP) shocks in a separate investment-producing sector. However, this interpretation is strictly valid only when some stringent conditions are satisfied. Some of these conditions are at odds with the data. Using a two-sector model whose calibration is based on the U.S. Input-Output Tables, the authors consider the implications of relaxing several of these conditions. They show how the effects of IST shocks in a one-sector model differ from those of MFP shocks to an investment-producing sector of a two-sector model. MFP shocks induce a positive short-run correlation between consumption and investment consistent with U.S. data, while IST shocks do not. Illus. This is a print on demand report.
