| Tiivistelmä: | This paper examines empirically the cost-reducing impacts of recent dramatic increases in stocks of "high-tech" office and information technology equipment in U.S. manufacturing industries through 1970-1980s. Te study bases the empirical specification of a dynamic factor demand model on the theory of cost and production, with labor, energy, and nonenergy intermediate materials as variable inputs, and O equipment, "other" equipment, and structures as quasi-fixed inputs. For each industry the ratio of marginal benefits of O investment to marginal costs qo have been computed, as well as a number of related elasticities highlighting different aspects of the productivity effects of high-tech capital investment. |
