We document that firms prefer counties with higher ethnic diversity in locating their interstate investments, especially for those pursuing innovation, seeking to establish service centers, or managing a diverse workforce. We also find some evidence that interstate investment in high ethnic diversity locations results in increased patent applications, sales growth, positive media coverage, and overall operating performance. Taken together, we show that firms prefer to invest in ethnically diverse locations as they recognize the potential benefits of leveraging a diverse labor supply, such as enhancing problem-solving, innovation, and performance. We must recognize that difference is a reason for celebration and growth, rather than a reason for destruction. (Audre Lorde)

This study examines the effect of banking market consolidations via mergers and acquisitions (M&As) on the role of banks in intermediating corporate tax planning through offshore tax haven operations. We find that bank clients significantly increase their tax haven operations after their banks are merged with others. In addition, such an increase is greater when a commercial bank merges with an investment bank and when the clients have greater tax planning opportunities. We also employ network analyses to show that the propensity for a client to expand its operations into a new tax haven country increases significantly when its relationship bank enters into this country through an M&A. Collectively, our findings reveal that bank M&As enhance banks’ tax intermediation capability.
