Corporate Demography and Empirical Industrial Organization: A Critical Appraisal

The emerging field of corporate demography views corporations and industries in a similar way to human or animal individuals and groups. In spite of a surprisingly large overlap of subject matter with economics, corporate demography is not well-known by, nor easily accessible to economists. An extremely useful recent book, The Demography of Corporations and Industries, by Glenn R. Carroll and Michael T. Hannan (2000) should change that. This review essay critically examines corporate demography from an economic viewpoint. The very different view of competition in corporate demography gets particular attention.

Conclusion The results of these models suggest that there may be discrimination in the award process.We find that the award rate for black applicants is relatively lower than that of white applicants with similar characteristics. A significant race and sex effect remains in the variation of the award rate after all eligibility-related factors and other factors have been controlled for.The second model is more interesting, in that the race and sex effects are significant even after looking only at eligible applicants.However, we do not know how much of these effects are caused by our imputation of the eligibility criterion from the survey data instead of the explicit criterion from the program data.
