Abstract

Offensive and Defensive Marketing: Closed-Loop Duopoly Strategies

A modified Lanchester game is used to develop closed-loop strategies for offensive and defensive marketing expenditures of duopolistic competitors in a market share rivalry. Analysis of the model reveals that

  1. well-defined closed-loop strategies can be developed that show directly the influence of market share on offensive and defensive marketing;

  2. steady state is marked by balance between offensive and defensive marketing expenditures;

  3. defensive marketing is more critical than offensive marketing due to greater risk of loss under deviation from closed-loop strategies.

The last result would appear to have particularly important implications for both practice and research.
