摘要:

基于现实经济中广泛存在的偏好预测偏差和自我控制问题,以及投资实践中的投资业绩稳定目标,同时考虑消费者的动态偏好风险和投资业绩稳定约束,研究时间偏好不一致对消费和投资策略的影响。采用连续时间下的拟双曲贴现函数来刻画时间偏好的不一致性,并从财富约束的角度刻画投资业绩稳定,要求消费者的当前财富水平始终不能低于历史加权平均财富水平。研究发现,消费者对财富回撤风险的承担能力和风险资产投资比例会受到投资业绩稳定约束和时间偏好变化的共同影响,在相同的投资业绩稳定约束程度下,时间偏好不一致的消费者会将更多的财富投资于风险资产,降低消费-基准财富比率,为风险偏好与时间偏好的关系提供了理论上的支持。在投资业绩稳定约束下,时间偏好不一致性会降低消费对金融财富变化的敏感性,从时间偏好不一致和投资业绩稳定约束共同作用的角度解释了现实中的金融财富效应。

Abstract:

It is based on the self-control problem in real economy and the consistent performance requirement in investment practice. The existing literature has not researched on consumption and portfolio choices in a framework integrating time-inconsistent preferences and consistent performance. Considering time-varying impatience risk and consistent-performance constraint simultaneously, their joint impacts on optimal consumption and portfolio allocation are studied. According to Grenadier and Wang (2007), Harris and Laibson (2013), time-inconsistent preference is characterized by a quasi-hyperbolic discount function in continuous time. According to Chen and Tian (2012), consistent-performance constraint is defined by that the current wealth must stays at least on the level given by a weighted average of wealth in the past. The results show that the tolerance to the withdrawal in wealth and the optimal proportional allocation in risky asset are determined by the degree of consistent performance constraint and the change of time preference, which can provide theoretical support for the relationship between the time preference and risk taking and give better prediction for empirical facts such as investment behaviors in risky assets, financial wealth effect on consumption.

Key words: time-inconsistent preference, consistent performance, consumption, risky asset
