Abstract: | This paper calculates multifactor productivity trends in seven Canadian mining industries and relates changes in productivity to various factors, including changes in output and factor prices and the decline in the quality of the ore being mined. It is found that productivity decline in mining has been pronounced and tended to predate that of manufacturing by several years. There are indications that the most important factors in the decline have been the fall in mineral grade, contraction of output, increases in interest rates and an apparent decline in the rate of technical innovation. |
