[Using new data for the universe of firms covered in Amadeus, we reconstruct the portfolios of shareholders who hold equity stakes in private- and publicly traded European firms. We find great heterogeneity in the degree of portfolio diversification across large shareholders. Exploiting this heterogeneity, we document that firms controlled by diversified large shareholders undertake riskier investments than firms controlled by nondiversified large shareholders. The impact of large shareholder diversification on corporate risk-taking is both economically and statistically significant. Our results have important implications at the policy level because they identify one channel through which policy changes can improve economic welfare.]

[Portfolio diversification of firms’ controlling owners influences their firms’ capital investment. Empirically, the effect of owners’ portfolio diversification on their firms’ investment levels is positive for publicly traded firms and tends to be negative for privately held ones. These findings are consistent with predictions of a model in which a risk-averse investor simultaneously chooses her portfolio structure, and both the level and riskiness of capital investment of the firm she controls, and in which the firm can be potentially constrained in its capital investment choices. Overall, our results indicate that owners’ portfolio underdiversification and firms’ financial constraints can affect firms’ resource allocation.]

Using the entire universe of Bankscope and Amadeus Top 250,000 we construct the portfolios of shareholders who hold equity stakes in publicly traded and privately held European banks for each year over the period 1999–2008. We show that about 62% of banks’ ultimate largest shareholders are diversified investors, holding on average equity investments from thirteen companies in their portfolio. We exploit this heterogeneity to investigate the impact of their portfolio diversification on bank risk-taking. Our results show that banks with more diversified shareholders undertake more risks. This relation is both statistically significant and economically sizeable. Overall, these findings contribute to the literature by studying for the first time a specific channel through which financial development, in the form of bank shareholders’ diversification, affects the banks’ risk-taking decisions.

We extend the literature on how managerial traits relate to corporate choices by documenting that firms run by female CEOs have lower leverage, less volatile earnings, and a higher chance of survival than otherwise similar firms run by male CEOs. Additionally, transitions from male to female CEOs (or vice versa) are associated with economically and statistically significant reductions (increases) in corporate risk-taking. The results are robust to controlling for the endogenous matching between firms and CEOs using a variety of econometric techniques. We further document that this risk-avoidance behavior appears to lead to distortions in the capital allocation process. These results potentially have important macroeconomic implications for long-term economic growth.

Using a large sample of US public debt issues we show that personal connections between directors of issuing companies and rating agencies result in higher credit ratings. We estimate the average effect to be about one notch. Moreover, our tests indicate that issues by connected firms are 30% more likely to be rated A3. Results are robust to several alternative tests including additional controls for managerial traits, firm fixed effects, and propensity score matching. Furthermore, our tests on default rates and bond yields suggest that personal connections act as a mechanism to reduce asymmetric information between the rating agency and the issuer.
