Being small at the right moment: Path dependence after a shift in the technological regime
通过基于主体的模型研究技术变革如何影响行业集中度，发现资本品部门技术加速导致下游消费品部门企业生产率和技能分化，进而提高市场集中度；后期主导企业在初期规模较小，但得益于劳动力市场的幸运结果，其资本选择与员工技能形成良性循环。
Abstract This paper explores the impact of technological change on industry concentration and the underlying firm dynamics. Within the agent-based model EURACE@Unibi, it is shown that an exogenous acceleration in technological change in the capital goods sector leads to a diverging firm population in the downstream consumption goods sector in terms of productivities and skills and in turn also to a higher market concentration. A novel ex-post analysis at the micro level shows that the later dominant firms were relatively small at the beginning but benefited from a virtuous cycle between their capital choice and the skill level within their workforce that is initiated by a fortunate outcome on the labor market.
