This paper analyzes the macroeconomic and welfare effects of population aging and Social Security reform. First, a stochastic overlapping-generations model with heterogeneous agents is carefully extended to an aging society. The model uses the intermediate population projection of the Trustee...

This paper provides a preliminary investigation into the lifetime cost of children upon a household's lifetime wealth. By comparing the lifetime cost function of a household with children compared to the lifetime cost function of a household without children, an intertemporal equivalence scale...

This paper focuses on the identification and estimation of the intertemporal and intratemporal elasticities of substitution for the wife and separately for the husband using individual Euler equations. To that end, the household is represented as a group of agents making joint decisions. By...

The paper explores the implications of means of payment substitutability and capital mobility on the properties of the money demand, using the Thomas (1985) stochastic dynamic optimising model, where the specific role of money is explicitly accounted for. Extending the model to a case in which...

This paper explores the quantitative impact of the Baby Boom on stock and bond returns. It constructs a neoclassical growth model with overlapping generations, in which agents make a portfolio decision over risky capital and safe bonds in zero net supply. The model has exogenous technology and...

This paper presents a model developed to explain the life-cycle patterns in both homeownership and portfolio allocation, and the relationship between them, using a model of rational agents. Two key innovations are incorporated into this model. First, housing is explicitly modeled as both a...

In this article we construct a model in which agents exhibit preference for ownership with respect to a durable (house). Ownership is modeled as a continuous function of debt service normalized by the price of the house. We study the utility optimization problem of an investor not endowed with...

This paper investigates the uncertainty in variance and covariance of asset returns. It is commonly believed that these second moments can be estimated very accurately. However, time varying volatility and nonnormality of asset returns can lead to imprecise variance estimates. Using CRSP value...

I develop a Markov model of samrt money chasing past winning funds while taking into account associated costs. The model also allows market capital entry and exit. The steady-state capital allocations re derived using constant transition probabilities. The results sugget that down side risk is...

We solve in closed form the optimal consumption / portfolio choice problem for the class of isoelastic utility functions under incomplete information about the mean return of the stock price. Our approach consists in converting the original investor's problem into an equivalent program where the...
