Microeconomic foundations of corporate strategy

This paper examines several approaches to corporate strategic planning in the context of their relationship to the microeconomic theory of the firm, and discusses the implications of that theory for corporate strategy in general. Specifically, three types of analytical tools are discussed: (1) analytical portfolio models; (2) business simulation models; and (3) optimization models. Examples of how the three types of tools are used in corporate decision-making are given, and certain limitations are cited. The limitations include, for example, the inability of some of the models to deal with interdependencies across business units in production resources or output demand. Finally, the paper examines the approach to strategic planning known as the ‘strategy matrix’, which explicitly allows for interdependices across business units. The use of the strategy matrix by a major petroleum company is discussed in some detail.
