The moderating role of board gender diversity on the relationship between firm opacity and stock returns

In this study, we examine the impact of board gender diversity on the association between firm opacity and stock price crash. We utilize the negative shock of the 2007–2008 financial crisis to capital markets to examine whether firms with gender-diverse boards witnessed lower stock price crashes due to their lower opacity ex ante. Using a sample of S&P 1500 firms spanning the period 2005–2008, we employ a difference-in-differences research design and find that firms with high opacity ex ante witness more negative returns ex post. We also find that gender-diverse firms ex ante witness less negative returns ex post. Finally, our analysis reveals the moderating role that board gender diversity plays in the association between firm opacity and stock returns around the financial crisis. We subject our results to a range of robustness checks, including instrumental variable regressions, matched-sample analyses, and a set of falsification and placebo tests. Overall, we provide evidence that board gender diversity is associated with increased transparency in financial reporting, which pays off in times of crisis.
