Coresidence With Husband’s Parents,Labor Supply,and Duration to First Birth

This article investigates the time to first birth, treating coresidence with husband’s parents and labor supply as endogenous and using representative data on Taiwanese married women born during 1933–1968. We use a full-information maximum likelihood estimator for a duration model with endogenous binary variables. Results controlling for endogeneity suggest that both coresidence and working are associated with a delay in childbearing, reversing the effect of coresidence on the timing of first birth but not that of working. Women in earlier cohorts tend to choose coresidency and not working, and an increasing number of women from later cohorts choose to do both or to work only.     

Age-distribution dynamics and aging indexes

I analyze the dynamics of the age distribution as some vital rates change. When the fertility or mortality rate declines, the age distribution often manifests a dynamic stochastic-dominance relationship. I also propose some alternative indexes for measuring population aging. These indexes are closely connected with the age-distribution dynamics and contain more refined information about the distribution of age among the old.     

Bequest division and population growth: A lineal extinction probability approach

This study uses a lineal-extinction-probability-minimization approach proposed by Chu (1991) to study the relation between bequest division and population growth. Using a Markov branching process and “first-degree stochastic dominance” technique, our model's results imply that any specific bequest division, primogeniture or equal divisions, does not necessarily increase or reduce the population growth by itself. Whether the population does grow, or by how much, will be determined by the concurrent social-economic conditions. We find that if all family heads faced an increasing MRTS technology and/or a relatively unfair market chance, then they would tend to choose an unequal division as their optimal bequest policy, and population growth would increase. However, if an equal division was adopted involuntarily by family heads or was enforced by laws, then the population growth might decline. Received: 26 November 1999/Accepted: 26 October 2000
