| 摘要 | This paper starts from the the assessment that there is no good theory in the social sciences that would tell us whether fertility on low-fertility countries is likely to recover in the future, stay around its current level or continue to fall. This question is key to the discussion whether or not governments should take action aimed at influencing the fertility rate. To enhance the scholarly discussion in this field, the paper introduces a clearly defined hypothesis which describes plausible self-reinforcing mechanisms that would result if unchecked, in a continued decrease of the number of births in the countries affected. This hypothesis has three components: a demographic one based on the negative population growth momentum, i.e., the fact that fewer potential mothers in the future will result in fewer births; a sociological one based on the assumption that ideal family size for the younger cohorts is declining as a consequence of the lower actual fertility they see in previous cohorts; and an economic one based on the first part of Easterlins (1980) relative income hypothesis, namely, that fertility results from the combination of aspirations and expected income, and assuming that aspirations of young adults are on an increasing trajectory while the expected income for the younger cohorts declines, partly as a consequence of population ageing induced by low fertility. All three factors would work towards a downward spiral in births in the future. If there is reason to assume that such mechanisms will indeed be at work, then this should strengthen the motivation of governments to take immediate action (possibly through policies addressing the tempo effect) in order to still escape from the expected trap. |
