This paper investigates whether multinational firms are less or more efficient in innovation activities than domestic firms. Using patents and citations scaled by R&D expenses and R&D capital as measures of innovation efficiency, we find that multinational firms have lower levels of innovation efficiency than purely domestic firms. This finding has been supported by additional evidence using peer pressure as an exogenous shock to firms' strategy of going international. We also find that information asymmetry and the low cost of capital could be the major channels through which global diversification impacts innovation efficiency adversely. Our results further suggest that innovation efficiency is more valuable to multinational firms that mainly diversify into developed markets or markets with better patent protection.

Using Morningstar mutual fund stewardship grade data, we find that the governance mechanisms of mutual funds play a key role in their monitoring of portfolio firms and in their investment decisions. Mutual funds with better governance practices tend to vote responsibly on corporate governance proposals of their portfolio firms and also provide better return performance. Furthermore, these funds tend to avoid investing in poorly governed firms. The results suggest that funds with quality governance are more likely to act in the interest of their investors, and that costs associated with funds' monitoring of their portfolio firms do not adversely affect their return performance.

This study explores whether a firm’s auditor choice affects its ability to access foreign equity capital. Using the equity holdings of 35,665 foreign mutual funds from 30 countries for the period 1998–2009, we find evidence that appointing a Big 4 auditor is associated with the increased level of foreign mutual fund ownership in firms. Our results are robust when conditioned on firm-level information asymmetries, country-level information disclosure quality, and when employing the Enron–Andersen fiasco as the natural experiment. Furthermore, appointing Big 4 auditors is particularly important for firms to attract foreign capital during the 2008 global financial crisis.
