Invention and Innovation Under Alternative Market Structures: The Case of Natural Resources

Partha Dasgupta, Richard Gilbert and Joseph Stiglitz

The Review of Economic Studies, 1982, vol. 49, issue 4, 567-582

Abstract: This paper examines the interactions between market structure and resource allocation over time when there is endogenous technical progress. The structures considered are a planned economy, pure monopoly, and competition with patent rights. In an efficient allocation the date of invention coincides with the date of innovation (the date at which technology is used). This is also true with a pure monopoly, but monopoly retards technical progress relative to the efficient level. Competition for patents rights to a new technology results in excessively rapid technical progress if the resource endowment of the economy is sufficiently large. Also, competition may lead to "sleeping patents" where invention strictly precedes the date of innovation.
