We analyze the logical strength of theorems on marriage problems with a fixed finite number of solutions via the techniques of reverse mathematics. We show that if a marriage problem has k solutions, then there is a finite set of boys such that the marriage problem restricted to this set has exactly k solutions, each of which extend uniquely to a solution of the original marriage problem. The s...

We study a group of young women in rural Malawi who were exposed to a cash transfer experiment as adolescents. More than two years after the end of transfers, we find that the substantial short-term benefits of the program have largely evaporated. Unconditional cash transfers (UCT) caused a shortterm delay of marriage, fertility, and HIV infection, but the ending of the program is immediately f...

It is often asserted that the declining fertility rate in Japan is closely associated with the increasing number of women who receive a higher education. This study investigates that relationship from the theoretical perspective of social stratification. Specifically, I incorporate the outlook of social stratification with demographic approaches by analyzing the decline in fertility in relation...

The effect of the socioeconomic characteristics in one generation on the socioeconomic achievement of the next generation is the central concern of social stratification research. Researchers typically address this issue by analyzing the associations between the characteristics of parents and offspring. This approach, however, focuses on observed parent-offspring pairs and ignores that changes ...

Despite interest in the potential of the welfare system as a tool to affect marriage behaviors among low-income women, little is known about how welfare participation affects decisions to marry. We employ an event history approach to examine transitions to marriage over a five-year period among mothers who have had a non-marital birth. We find that welfare participation under the Temporary Assi...
