World Copper Market 1951-1975 Dataset


This data describes the world copper market from 1951 through 1975. In an example, in Gill, the outcome variable (of a 2 stage estimation) is the world consumption of copper for the 25 years. The explanatory variables are the world consumption of copper in 1000 metric tons, the constant dollar adjusted price of copper, the price of a substitute, aluminum, an index of real per capita income base 1970, an annual measure of manufacturer inventory change, and a time trend.
