Career Consequences of Firm Heterogeneity for Young Workers: First Job and Firm Size
利用西班牙行政数据，研究第一份工作进入大企业还是小企业对工人长期职业发展的影响，发现大企业能带来持续的职业优势，机制在于更好的技能培养。
I study the long-term effects of landing a first job at a large firm versus a small one using Spanish administrative data. Size could be a relevant employer attribute for inexperienced workers since large firms are associated with greater productivity, wages, and training. The key empirical challenge is selection into first jobs based on unobserved worker characteristics. I develop an instrumental variable approach that, keeping business cycle conditions fixed, leverages variation in the composition of labor demand that labor market entrants face. Initially matching with a larger firm persistently improves long-term outcomes, even through subsequent jobs. Mechanisms suggest better skill development at large firms.
