Tests of Alternative Theories of Firm Growth
利用1976-1982年制造业企业数据，发现企业增长随年龄和规模递减，支持Jovanovic的学习理论，但否定吉布拉定律。
This study examines the relationships among firm growth, firm size, and firm age for a sample of manufacturing firms between 1976 and 1982. Firm growth is found to decrease with firm age and firm size. These findings are robust to alternative assumptions concerning the effects of sample censoring and the functional form of the growth relationship. The inverse growth-age relationship is consistent with a theory of firm learning proposed by Boyan Jovanovic while the inverse growth-size relationship is inconsistent with a number of theories that assume or imply Gibrat's law.
