We analyze a duopoly through a differential game, in which the players set prices as functions of time. Under reasonable assumptions, we find that prices first decline, then increase. The market share of the biggest firm grows initially but decreases later. It is demonstrated that a firm may...

Using financial measures of performance we investigate the sources of value creation in the U.S. brewing industry between 1969 and 1979. We find that market share gains in this industry at this time are not correlated with changes in value and that the performance of individual leading firms is...

We make two clarifying comments on a recent paper by Naylor and Tapon (Naylor, T. H., F. Tapon. 1982. The capital asset pricing model: An evaluation of its potential as a strategic planning tool. Management Sci. 28 1166-1173.). The conclusions of their paper are significantly affected by this.

This article studies the implications of experience curves and brand loyalty for optimal dynamic pricing policy. In a continuous time model, we synthesize several results from the literature on open loop equilibria. Specifically, we show that prices should decrease over time for high discount...

Business Portfolio Planning techniques often suggest that firms should invest in industries with high profitability, high growth, or other attractive characteristics. Critiquing this view, we suggest that the same factors which lead to high profitability in an industry may cause its inefficient...

Several papers in the recent marketing literature have suggested that delegation in distribution (e.g., the use of independent middlemen) helps manufacturers to precommit strategically to profit-enhancing competitive actions. Further, the literature suggests that the profitability of such...

An economic theory of habit formation through consumption learning is developed to explain order differences in relative sales promotion expenditures among brands. The theory applies to consumer brands in equilibrium markets, where consumer information from sources other than advertising, sales...
