Individual Heterogeneity?income Stratification And Consumption Differences

In the context of consumption upgrading,the Chinese consumer's preferences are gradually showing a personalized,fashion,quality characteristics.At the same time,the consumption of residents has gone beyond the basic needs of survival,and gradually become an important label of self-expression and identity.In this case,the assumption that the traditional consumption theory relies on the representation or homogeneity of consumption,it is difficult to describe the consumer preferences and behavioral characteristics of the residents in the real economy.In addition,the traditional consumption theory is mostly confined to the theoretical framework of neoclassical economics,its basic hypothesis is rational reason hypothesis.However,experimental studies on micro-individuals show that rational human assumptions are often violated.In order to grasp the heterogeneity of the residents in the current economy and their heterogeneity in the current economy,this paper absorb some basic ideas and methods of the behavioral consumption theory in recent years,trying to put forward the assumption of individual heterogeneity,This paper makes a theoretical discussion on the differences in the marginal consumption propensity of Chinese residents with different income levels and makes empirical analysis using metrological tools such as quantile regression.In the aspect of theoretical modeling,this paper first introduces the consumption decision game model,which shows that the individuals with different income levels have different self-control ability in consumption.Subsequently,this basic hypothesis is introduced into the hyperbolic discount model of behavioral economics.It is found that the marginal propensity to consume of individuals with different income levels will increase with the increase of income points in the same group.In the empirical aspect,this paper uses the Chinese household income survey(CHIP2013)data,respectively,for the Chinese residents,between different income groups,between urban and rural areas and different regions between the regression,and on the basis of counterfactual break down.It was found that the difference in marginal propensity to consume among different groups,or between different groups,was indeed caused by the heterogeneity of individual income.That is,the empirical results confirm the above theoretical hypothesis.
