The Rise of the Service Economy
分析高技能劳动力如何推动服务部门增长，理论表明生产率提升使需求转向技能密集型服务，导致技能溢价和相对价格上升。
This paper analyzes the role of specialized high-skilled labor in the disproportionate growth of the service sector. Empirically, the importance of skill-intensive services has risen during a period of increasing relative wages and quantities of high-skilled labor. We develop a theory in which demand shifts toward more skill-intensive output as productivity rises, increasing the importance of market services relative to home production. Consistent with the data, the theory predicts a rising level of skill, skill premium, and relative price of services that is linked to this skill premium.
