Does the Aging Aggravate Urbans Consumption Inequality? ——Based on the Analysis of Age Effect Adjustment Model

doi:10.3969/j.issn.1005-6378.2018.05.010

Abstract

Abstract: When studying the impact of aging on the consumption inequality, the most difficult point is how to adjust the age effect, i.e., how to eliminate the cohort effects and how to deal with the interference of age-related factors. For this reason, we calculate a new age-adjusted Gini coefficient by using the CHIP urban survey data from 1995 to 2013. First, we employ a multivariate regression model to isolate the age effects while controlling other determinants of consumption constant. Then, the consumption distribution of perfect equality is determined and age-adjusted Gini coefficient is derived finally. In this way, we eliminate the interference of age-related factors and accurately estimate the impact of aging on consumption inequality. The results show that:(1)The age-adjusted Gini coefficient is gradually increased, showing the trend of consumption inequality of urban residents in China is enhanced after excluding the influence of aging.(2)The classical Gini coefficient is always smaller than age adjusted Gini coefficient, indicating that the aging of urban residents in China has a negative effect on consumption inequality.(3)The age effect of consumption inequality of urban resident is at a low level but the role of age effects in consumption inequality will become more apparent in the future.

Key words: consumption inequality, age effects, Gini coefficient, aging
