Technological change is investment specific. Depreciation in this environment is an economic, not a physical, concept. The vintage capital economy's balanced-growth paths and transitional dynamics are analyzed. The transitional dynamics are markedly different from the standard neoclassical growth model. An overlapping generations model of marriage and divorce is constructed to analyze family structure and intergenerational mobility.
Agents differ by sex, marital status, and human capital.
Single agents meet in a marriage market and decide whether to accept or reject proposals to wed. Married couples must decide whether to separate or not. Parents invest in their children depending on their wherewithal. A simulated version of the theoretical prototype can generate an equilibrium with a significant number of female-headed families and a high degree of persistence in income across generations. To illustrate the model's mechanics, the effects of two anti-poverty policies, namely child support and welfare, are investigated.
