This paper investigates whether and how company boards affect firm performance. It sheds light on decisions taken by these types of high-level managers and the importance of member variety in the board profit function. I study a regulation in France that exogenously changed boards by mandating a minimum representation of each gender for firms above a certain size threshold. I show that the gender quota constrains firms to diversify boards across a variety of individual traits such as age and nationality. New boards increase various measures of profitability by around 7%. A decomposition of all margins of adjustments indicates that the rise in profits occurs mainly through cuts in variable labor costs. Results suggest that new boards use temporary high-skilled workers to enter new markets and increase firm revenue. I identify a non-linear mapping from member characteristics to firm outcomes. I relate profits to changes in board members to infer switchers' ability and separately quantify the relevance of member variety. I find that ability explains around 35% of the profit variance but that observable traits matter at the margin. I tie back the substantial gains from the regulation to the diversification of individual traits which are complementary inputs in boards.

We show how local worker flow adjustment margins yield a theory-consistent sufficient statistic approximating the welfare effects of local shocks. Furthermore, we isolate a city’s insurance value as this approximation’s second-order term. Leveraging rich labor flows data across occupations, industries, and cities in France, we estimate spatial and non-spatial flows responses to local labor demand shocks. Less economically diverse French cities experience deeper contractions in gross outflows following negative shocks. In contrast, more economic concentration begets a modestly larger increase in gross worker flows following positive shocks. Altogether, we uncover a sizable welfare insurance gains from local economic diversity.
