将生育偏好的异质性纳入小型开放经济的世代重叠模型，考察了现收现付制（PAYG）社会保障规模的变化对个人生育选择和经济体人口增长的影响。研究表明，如果现收现付制的社会保障制度涉及到不同缴费的退休人员之间的再分配，则该制度将通过增加有子女的个人数量和父母的子女数量来提高人口增长率，而如果不涉及再分配，则该制度不影响个人的生育决策。
Incorporating heterogeneity in preference to having children into an overlapping generations model of a small open economy, we examine the effects of changes in the size of pay‐as‐you‐go (PAYG) social security on fertility choices of individuals and population growth of the economy. It is shown that PAYG social security will raise population growth by increasing the number of individuals who have children and the number of children parents have if the system involves redistribution between retirees with different contributions, whereas, if it has no redistribution, PAYG social security does not affect the fertility decisions of individuals.
