Occupational Choice with Endogenous Spillovers
研究将生产性努力和社交性努力与职业选择及内生溢出效应相结合，发现更有天赋的人工作更努力、贡献更多外部性，但倾向于隔离；平均社交提高职业生产率，职业规模随协同效应增长，个体在努力和职业选择上存在低效，并推导出最优补贴和识别过度拥挤部门的规则。
Abstract We study a model that integrates productive and socialising efforts with occupational choice, and endogenous spillovers. We show that more talented individuals work harder and contribute more to externalities, but also have incentives to segregate. Average socialising increases the productivity of the occupation. The size of an occupation grows with its synergies. Individuals underinvest in productive and socialising effort, and sort themselves inefficiently into occupations. We derive the optimal subsidy for sorting into different occupations. Finally, we derive a rule to identify overpopulated sectors and establish the connection between inequality of talents, socialising, productive efforts and occupation size.
