Age structure of the population and the choice of household financial assets

Abstract

China is undergoing changes in its demographic structure, and the burden of raising children and caring for the elderly is negatively affecting the welfare of Chinese families. Optimising the financial structure of households may be an effective solution. Using data from the 2017 Chinese Household Finance Survey, in this study, we empirically analyse how the age structure of the population affects a household’s finances by applying probit and tobit models. It was found that an increase in the proportion of infants in a family has a crowding-out effect on its investment in risky and deposit assets, and an increase in the proportion of elderly family members encourages the replacement of risky assets with savings. Further mechanism tests showed that the presence of infants affects the choice of financial assets by crowding a family’s labour or leisure time, increasing expenditures, and changing a family’s cash demand, while the presence of the elderly changes household finances because a family’s risk preferences are altered by the weakened cognitive abilities of the elderly. Finally, in this article, we advance some policy suggestions, such as regulating capital market management, increasing birth subsidies, and improving the financial literacy of the elderly, to ensure future pension security.
