Input-output tables for the U.S.A. and Japan are used to estimate changes in energy efficiency during the period 1960–1980. We used a method of Pasinetti which takes into account changes in the energy efficiency with which additions to capital stock are produced. Although we find substantial...

The dramatic increase in energy efficiency in the U.S. economy since the early 1970s has been the subject of much study and controversy. Among the factors responsible for improved energy efficiency are better housekeeping measures, technological innovations and a changing product mix. These...

The U.S. input-output tables for 1972 and 1977 are used to examine the early adjustment of the service sector to the energy price shock of 1973–1974. IO analysis allows us to look at the indirect as well as direct changes in energy use intensity. We find a substantial decline in both primary...
