We solve and estimate a life-cycle model with earnings risk and liquidity constraints in the presence of tax-deferred retirement accounts (TDAs). We explicitly consider two very different types of households (with TDAs): direct and indirect stockholders. The latter hold stocks only through TDAs...

Motivated by the success of internal habit formation preferences in explaining asset pricing puzzles, we introduce these preferences in a life-cycle model of consumption and portfolio choice with liquidity constraints, undiversifiable labor income risk and stock-market participation costs. In...

This paper analyzes the dynamic politico-economic equilibrium of a model where repeated voting on social security and the evolution of household characteristics in general equilibrium are mutually affected over time. In particular, we incorporate within-cohort heterogeneity in a two-period...

We use all available waves of the Survey of Consumer Finances to document the evolution of the wealth distribution in the US since the 1980s. Relying on the shape of this distribution we then estimate a life-cycle incomplete markets model. We find that considering a wide range of net worth...

Even though smokers incur higher health expenditures than nonsmokers of the same age, smokers have significantly higher mortality rates, so the expected lifetime health expenditure for a smoker is actually lower than for a nonsmoker. Because of this fact, some politicians and policy-makers have...

This paper characterizes the solution to a consumption/savings decision problem in which one of the consumption goods involves transaction costs. It then analyzes how such adjustment costs affect consumers' risk attitudes. Previous studies have suggested that transaction costs, by resulting in...

Two key components of the recent U.S. health reform are a new regulation of the individual health insurance market and an increase in income redistribution in the economy. Which component contributes more to the welfare outcome of the reform? We address this question by constructing a general...

In this paper, I develop a dynamic general equilibrium model to study the sensitivity of house price changes with respect to credit constraints. I find that house prices are sensitive to changes of the down payment requirements if owner-occupied houses and rental houses are inelastically...

Investment booms and asset "bubbles" are often the consequence of heavily leveraged borrowing and speculations of persistent growth in asset demand. We show theoretically that dynamic interactions between elastic credit supply (due to leveraged borrowing) and persistent credit demand (due to...

In a Bewley model with endogenous price volatility, home ownership and mobility across locations and jobs, we assess the contribution of financial constraints, housing illiquidities and house price risk to home ownership over the life cycle. The model can explain the rise in home ownership and...
