Abstract: | The population ecology model of formal organizations is used to study how adaptive maneuvers enable organizations to maintain themselves in a distribution of like organizations and, ultimately, to understand how the process of selection leads to survival and reproduction of certain types of organization and attrition of other types of organizations. Selection is readily affected by organization innovation, whether administrative or technological. This research dealt with how the steel rail may have affected the survival of 214 railroads in a fourteen-state area of the U.S. from 1860 to 1890. The findings indicate that two organizational characteristics, age of railroad and size of a rail operation, contributed more to rail survival than did technological innovation. Several methodological and theoretical issues are discussed which surround the choice of the population ocology model and the conduct of this research. |
