This paper documents that senior plant managers in less-developed countries spend more time dealing with government rules and regulations than their counterparts in richer countries. These facts are interpreted through the lens of a span-of-control growth model, in which top managers run heterogeneous production plants, employing middle managers as well as production workers. The model implies that increasing the time burden on top management leads to equilibrium changes in wages, occupational sorting, the size distribution of production plants and ultimately, to a reduction in aggregate output. These consequences hold even when the time burden is symmetric across all plants. Quantitative results show that increasing the burden on managers' time from the levels observed in Denmark to the higher levels observed in poorer countries have substantial consequences. Imposing the average time spent on regulations in Argentina reduces aggregate output by about 1/3 and mean plant size by more than 5 employees. Results contribute to rationalizing differences in plant size and output across countries via a channel hitherto unexplored in the literature.
