While economists have long recognized the tradeoff between specialization gains and coordination costs, less attention has been paid to its implications for human capital accumulation. A finer division of labor allows workers to develop greater expertise through repeated performance of narrowly defined tasks, but may also reduce opportunities to learn from coworkers by limiting interactions and knowledge exchange. We study these static and dynamic tradeoffs using population-wide Norwegian employer–employee records, linked workplace surveys, quasi-experimental variation in coworker availability, and randomized experiments with workers and managers.
