We study the decisions of international asset managers to outsource portfolio management of their funds and we link these decisions to market integration. Using a structural model of selfselection, we endogenize the decision to outsource in a comprehensive sample of international mutual funds and identify both performance and non-performance related determinants of outsourcing. Outsourcing fund management generates net positive gains to fund families of around 8-17 bp per month despite the ex-post underperformance of outsource funds relative to inhouse funds. Then, we establish that the performance improvements from outsourcing are directly related to segmentation in the underlying asset markets.
