摘　　要：研究了在经济代理人通过不可逆退休时间选择来调整劳动时间框架下的最优消费和投资问题,主要考虑风险资产派发红利的情形.运用随机控制方法,求解使得消费-闲暇预期效用最大化的最优策略.最优投资组合及最优退休时刻表明,代理人在为提前退休积累财富的同时,也能最佳享受消费和闲暇所带来的快乐.Optimal consumption and portfolio choices in a framework where in- vestors adjust their labor supply through an irreversible choice of retirement time are studied. Consider the case of the dividend-payment of risk assets when the agent makes portfolio selections. By using the method of stochastic control, the expected utility maximization of consumption-leisure utility is discussed, and the optimal strategies are obtained. Optimal portfolio and optimal retirement time show that the agent can not only accumulate wealth for the early retirement, but also enjoy the consumption and leisure.
