There is growing evidence that worker productivity is contagious. This column examines the impact of co-worker networks on productivity using tools from network economics. There are indeed strong network effects in worker productivity, with increases in the productivity of an individual’s co-worker network leading to an increase in the individual’s productivity. Also, exposure to trained workers increases the productivity of non-trained workers. The findings have implications for the optimal structure of co-worker networks within firms.
