Partial Specialization and Heterogeneous Task Assignments
构建了一个包含多维技能和部分专业化的一般均衡模型，利用微观数据估计1980-2000年间职业内不平等增长的驱动因素，发现任务内容变化是主要解释因素。
I develop a general equilibrium model featuring multidimensional skills and partial specialization in tasks to quantify the impact of several determinants on within-occupation inequality growth from 1980 to 2000. The model introduces a new mechanism by which demand shifts affect inequality: Workers within the same occupation perform multiple and different tasks. I structurally estimate the model using microdata and account for inequality growth due to three sources: changes in occupation demand, changes in the task content of occupations, and changes in labor composition. My findings indicate that changes in task content explain the majority of within-occupation inequality growth.
