This paper estimates the causal effects of house-inheriting on heirs' labor supply, marriage, and fertility outcomes. Using administrative tax data from Taiwan, I apply a staggered Difference-in-Differences (DiD) design to estimate dynamic treatment effects. To address potentially confounding effects from the coincidence of parental death and house inheritance, I show that the impact of parental death is minimal, attributing most observed effects to wealth increases and homeownership acquisition. The findings reveal that inheritance significantly reduces labor supply, aligning with the literature on Carnegie effects that receiving inheritances discourages work. For unmarried sons, house-inheriting increases the likelihood of marriage by 2.8 percentage points and the number of children by 0.016. Similar fertility increases are observed among married couples receiving inheritances. The effects are more pronounced for daughters, as house inheritance is culturally less expected. Younger and less wealthy heirs experience larger impacts, suggesting that inheritance represents a substantial wealth effect for these groups. These findings indicate that homeownership is a key driver of household formation in Taiwanese culture.

Due to increasing longevity and declining fertility, families in many rich countries have experienced sharply rising aging-related care needs at the same time that the labor capacity within those families has fallen. How families meet those care needs given their constraints---and at what cost---is an increasingly important question. This paper shows that sudden declines in the health of elderly Taiwanese adults disrupts the life cycles of their adult children.  Rather than causing substitution away from the labor force, elderly parental health shocks are followed by increased mortality, poorer indicators of health, and reduced marriage and fertility rates. Burdensome care needs are likely a key mechanism, judging from the observable characteristics that predict particularly adverse responses to a parental stroke. We find evidence that allowing families to hire migrant care workers can attenuate the negative associations between old-age health issues and family outcomes, improving the survival, health, and well-being of adult children of the elderly.
