Over the last decades, firms have been incorporating digital technologies into their operations, a process known as digitalization. Nevertheless, understanding the link between digitalization and firm performance remains challenging. We propose a new firm-level measure of digital intensity based on textual analysis of business descriptions and quarterly earnings calls. To overcome endogeneity, we use two quasi-natural experiments: the COVID-19 pandemic and shocks involving suppliers affected by U.S. natural disasters. Non-technological firms with higher pre-shock digital intensity experience higher abnormal returns, higher profitability, and higher revenue growth during the shocks. The supply chain is one of the areas through which digitalization contributes to significantly mitigate the effects of these shocks, thereby enhancing firm resilience.

Horizontal directors, board members who also hold board seats in same-industry peers, are common in U.S. corporations. We posit that horizontal directorships can enhance the efficiency of corporate investment decisions. Horizontal directors enjoy access to current information flows, which help boards fulfill their roles of advising and monitoring – a form of learning from peers. We find that horizontal directorships are negatively related to investment inefficiency, and with over-investment in particular. Exogenous shocks to board composition provide a causal interpretation to our findings. Our paper contributes to a nuanced view of horizontal directors by highlighting their contribution to mitigate excessive investment.
