With the nations of the world becoming more interdependent, it is imperative to take international influences into account in understanding the organization of industry within a country. This book extends the structure/conduct/performance framework of analysis to present a fully specified simultaneous equation model of an open economy—Canada.By estimating a system of equations of all the major variables, the authors can identify which variables are dependent and which are independent. They are thus able to assess the relative importance of such factors as seller concentration, import competition, retailing structure, advertising expenditure, research and development spending, and technical and allocative efficiency in shaping the organization of industry in Canada. In addition, using both industry-level and firm-level data, the authors develop methods for assessing the effect of structural variables on diversification strategies and the consequences for market performance. They also study the effects of such variables on firms’ access to capital markets. The book concludes with a discussion of the implications of the findings for government policy.
