Abstract:In Chinese venture capital funds, Venture capitalists usually invested in the government’s designated projects and their own choosing items at the same time. Under this multi-tasking environment, the paper analyzes the incentive contract design problem for venture capitalists in three different organizational models. The main conclusions are: 1) If the importance among tasks is difference, or output distribution of different tasks is positive correlated, then the incentive intensity between different tasks does not necessarily complement each other, which extends Holmstrom and Milgrom's classic conclusion; 2) If different venture capital fund engaged in government’s designated projects and its own selecting items separately, then as the principal, the government could get higher net surplus in this specialization pattern; In particular, the principal would be benefited by introducing relative performance comparison in specialization pattern.
