We examine the effect of board interlocks on patenting and R&D spending for publicly traded companies in India. We exploit a corporate governance reform to address the endogeneity of board interlocks through exogenous changes mandated by the reform requiring a subset of firms to adjust their board structure. We rely on two difference-in-differences frameworks, comparing firms affected by the reform to unaffected firms as well as comparing within the set of firms that did not have to adjust their board structure those that still experienced an exogenous increase of their network size as a result of the reform to those that did not experience a change in their network size. We find that board interlocks have significant positive effects on both R&D and patenting. The evidence suggests that the impact on R&D is induced by information transmission through interlocks. The effect on patenting is driven by firms extending patent protection by patenting inventions abroad that they have already patented in India.

The literature on managerial style posits a linear relation between a chief executive officer's (CEOs) past experiences and firm risk. We show that there is a nonmonotonic relation between the intensity of CEOs’ early‐life exposure to fatal disasters and corporate risk‐taking. CEOs who experience fatal disasters without extremely negative consequences lead firms that behave more aggressively, whereas CEOs who witness the extreme downside of disasters behave more conservatively. These patterns manifest across various corporate policies including leverage, cash holdings, and acquisition activity. Ultimately, the link between CEOs’ disaster experience and corporate policies has real economic consequences on firm riskiness and cost of capital.
