Despite the fact that several finance case studies have investigated the performance to personal wealth outsourcing, little is known about how specific performance of personal wealth management illustrate with multi-theories. We apply a multiple perspective approach to explore theories of transaction cost, third party agent, resource-reliance, cooperative relationship, and performance efficacy. Our results indicate that most of these factors indeed significantly influence the degree of integration in cooperation relationship to lead the performance of personal wealth management. In particular, our study offers a theoretical rationale for why reactions to personal wealth outsourcing may occur, while providing practitioners with several means by which they can increase the value of outsourcing service.
