具有构成偏好的Roy模型中的职业隔离
Occupational segregation in a Roy model with composition preferences
AI总结：
本研究构建结合Roy模型比较优势与部门构成偏好的劳动力市场自选择模型，揭示构成偏好放大职业隔离、引发再分配与多样性的张力，还发现平权行动等微小冲击或参数阈值跨越可触发职业构成的临界点突变。
摘要：
我们提出了一个劳动力市场部门自选择模型，该模型结合了Roy模型中的比较优势与部门构成偏好。两个群体基于每个部门中异质的潜在收入和群体构成，在两个部门之间做出选择。潜在收入纳入了群体特定的人力资本积累和工资歧视。构成偏好被解释为反映了群体特定的设施偏好，以及同质性和对少数群体地位的厌恶。我们表明，构成偏好会放大职业隔离，并强调由此产生的再分配与多样性之间的张力。该模型还展现出从极端构成向更平衡构成的 tipping（临界点突变）现象。当与平权行动相关的微小推动将系统推向一个截然不同的均衡时，以及当支配金钱偏好与构成偏好相对重要性的参数跨越阈值、均衡集发生突变时，就会发生临界点突变。
英文摘要：
We propose a model of labor market sector self-selection that combines comparative advantage, as in the Roy model, and sector composition preference. Two groups choose between two sectors based on heterogeneous potential incomes and group compositions in each sector. Potential incomes incorporate group specific human capital accumulation and wage discrimination. Composition preferences are interpreted as reflecting group specific amenity preferences as well as homophily and aversion to minority status. We show that occupational segregation is amplified by the composition preferences and we highlight a resulting tension between redistribution and diversity. The model also exhibits tipping from extreme compositions to more balanced ones. Tipping occurs when a small nudge, associated with affirmative action, pushes the system to a very different equilibrium, and when the set of equilibria changes abruptly when a parameter governing the relative importance of pecuniary and composition preferences crosses a threshold.
