Richard Rumelt"Prior work has shown an association between diversification strategy and profitability. This paper replicates that association using more recent and complete data and goes on to investigate the sources of the association. Theoretical arguments are advanced which predict the association which will remain once the effects of varying industry profitability are removed. Empirical tests verify this prediction and permit the discrimination between the effects of industry and diversification strategy on profitability."

"I consider myself a mainstream researcher in the field of business policy, and the ideas I want to describe in this paper concern the foundations of a theory of business strategy that is rooted in economics. But is such a paper, whatever its merits, really appropriate at a conference entitled Non-traditional Approaches to Policy Research? Surprisingly, it is. The use of economic theory to model and explicate business strategy, as it is understood within the field of business policy, is distinctly non-traditional."
