The Contribution of Changing Energy and Import Prices to Changing Average Labor Productivity: A Profit Formulation for Canada
量化了1970年代加拿大能源和进口价格上涨对劳动生产率放缓的影响，发现能源价格每年降低劳动生产率0.53%，并修正了技术进步率。
In the 1970s there has been a noticeable labor productivity slowdown in Canada. In addition to contributions of such traditional variables as changes in capital intensity and quality of labor, this study quantifies contributions of higher energy and changing import prices to productivity changes. A Taylor series approximation to a restricted profit function representing the Canadian economy helps reveal that rising energy prices have reduced labor productivity by 0.53 percent per year after 1970 and that the underlying modified rates of technical progress in the 1960s and 1970s, having netted out price of energy—and import—effects, are not dissimilar.
