SUM MARYThe need for effective competitive strategy planning for a firm's survival and growth has long been recognized to be important. The identification and selection of good, or robust, market strategies must be based on the anticipation of the likely strategies of significant competitors, who should ideally be visualized as undergoing a similar process of assessing their own and other's goals and probable strategies.This paper reviews and evaluates the traditional economic and game theoretic approaches to competitive strategy analysis and presents an application of metagame analysis-an approach which has not previously been used in the strategic business environment. This approach, which appears to have some significant advantages over both economic and game theoretic approaches has been utilized and evaluated in a business firm (Dutta and King, forthcoming). An illustration of its use, which is based on a real-world application, is discussed.
ECONOMIC MODELS OF OLIGOPOLYAmerican business is characterized by oligopolistic markets.' The problem of 'oligopolistic interdependence' has been extensively studied, usually by modelling pricing interdependence among oligopolists-the most celebrated being the pricing behaviour theories of Cournot (1963) and Chamberlain (1933). One of the most significant modern contributions in this field has been Cyert and March's, A Behavioral Theory of the Firm (1963) which analysed 'the effects of such variables as goal setting, goal adjustment, information flow, search patterns, and other organizational characteristics on the firm's decisions ' (1963: 420) in pricing and output determination in imperfect markets. Lambin (1976) points out that the interdependence that prevails among competing firms in most markets is multi-dimensional-not just price-based. He notes the virtual absence of any systematic attempt 'to study the firm's marketing behaviour in oligopoly with specific reference to the marketing mix concept. ' He argues (1976: 21): 'Since most firms do follow the marketing mix in setting their marketing strategy and reactions, classical oligopoly theory does not provide the appropriate framework to analyse actual competitive marketing behavior.' According to Scherer (1970) 'oligopolistic industries are found to include between 50 and 60 per cent of all
