【摘要】：个人所得税递延政策一直被视作撬动商业养老保险需求的有力杠杆,其理论基础主要是新古典经济学框架下的贴现效用模型,认为对于理性消费者而言,购买个税递延型养老保险产品,会提升终身效用,消费者具有购买税延型商业养老保险的内在动力。但是,经验事实和行为经济学的研究表明,消费者是有限理性的,存在自我控制认知偏差,时间偏好具有动态不一致性,其行为受到心理因素的影响。在时间偏好动态不一致性的条件下,消费者对税延型商业养老保险的需求意愿和购买量是否会发生变化、发生何种变化,是非常值得深入探讨的问题。本文基于"二元心理系统假说"构建了准双曲线贴现效用模型,认为个体的短视和自我控制能力不足会导致消费者对商业养老保险的需求量明显小于时间一致性条件下的最优需求量,税收优惠政策的效果被削弱。通过个税递延优惠政策撬动商业养老保险市场发展、完善养老保险体系,需要在机制设计、消费者教育等方面协同努力。
[Abstract]:The deferred policy of personal income tax has been regarded as a powerful lever to leverage the demand of commercial old-age insurance. Its theoretical basis is the discounted utility model under the framework of neoclassical economics.Purchase of personal tax deferred pension insurance products, will enhance the effectiveness of life, consumers have the inherent motivation to buy tax extended commercial endowment insurance.However, empirical facts and behavioral economics research show that consumers are limited rational, there is self-control cognitive bias, time preference has dynamic inconsistency, their behavior is affected by psychological factors.Under the condition of dynamic inconsistency of time preference, whether the consumer's demand will change and what kind of change will take place to the tax extended commercial old-age insurance is a question that should be discussed deeply.In this paper, a quasi-hyperbolic discounted utility model is constructed based on the "dual psychological system hypothesis".It is concluded that the demand for commercial old-age insurance by consumers is obviously smaller than the optimal demand under the condition of time consistency and the effect of preferential tax policy is weakened because of the shortsightedness and lack of self-control ability of the individual.It is necessary to make concerted efforts in the design of mechanism and consumer education to promote the development of commercial old-age insurance market and perfect the pension insurance system through the preferential policy of personal tax deferral.
