In this article, we examine the effect of social trust on local bias. Our evidence suggests that institutional investors located in high-trust regions of the United States exhibit lower local bias. Moreover, we find that high-trust investors are better diversified, suggesting that trust helps accomplish greater diversification. The results are not due to firm, demographic, or local economic characteristics. Additional analysis reveals that the documented informational advantage in local holdings exists only in low-trust regions. We show that this finding is consistent with a trust explanation.

Between 1995 and 2006 about a quarter of merging firms hired boutique banks as their advisors on mergers and acquisitions (M&A). Boutique advisors, often specialized by industry, are generally smaller and more independent than full-service banks. This paper investigates firms' choice between boutique and full-service advisors and the impact of advisor choice on deal outcomes. We find that both acquirers and targets are more likely to choose boutique advisors in complex deals, suggesting that boutique advisors are chosen for their skill and expertise. After controlling for the endogenous choice of advisors, we find lower deal premiums when acquirers hire boutique advisors. In addition, boutique advisors spend more time, probably on due diligence and negotiation, to complete deals. Overall, our findings suggest that boutique advisors are chosen in more complex deals and they achieve more favorable deal outcomes.
