题目：Post-Match Investment and Dynamic Sorting between Capital and Labor
Abstract:By integrating frictional matching into a neoclassical framework of investment by firms, this paper analyzes dynamic sorting between capital and worker skills in the constrained social optimum. Opposite to the result without post-match investment, stronger complementarity between capital and skills in production increases the like- lihood that the socially efficient pattern of sorting is negative at the time of a match. However, sorting becomes positive eventually as capital in a match is increased by investment. Because the sorting pattern in a match reverses over time, the time profile of labor productivity is steeper for a high skill than for a low skill, and the difference in productivity between skills increases over time. Among any cohort of workers who become employed at the same time, the variance in labor productivity increases over time. There is also dispersion in labor productivity within each skill. The calibrated model shows that sorting is positive on average and that dispersion in labor productivity is significant both between skills and within each skill.
