This paper examines aggregate savings in a general equilibrium model where infinitely lived households face volatile (and possibly uncertain) income paths, hold a risk-free asset, and face a liquidity constraint. I first show that the equilibrium capital stock in an economy without uncertainty,...

This paper examines aggregate savings in a general equilibrium model where infinitely lived households face volatile (and possibly uncertain) income paths, hold a risk-free asset, and face a borrowing constraint. I first show that the equilibrium capital stock in an economy without uncertainty,...

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...

Two key components of the upcoming health reform are a reorganization 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...

A major source of insurance coverage for non-elderly adults in the US is employer-based health insurance market. Every participant of this market gets a tax subsidy since premiums are excluded from taxable income. However, people have different incentives to participate in the employer-based...

Having low income is one of the requirements for Medicaid eligibility. Given that earning ability is unobservable, once an individual with high labor income stops working it is impossible to distinguish him from those whose potential labor income is low. This can affect the ability of Medicaid...

In a model of a two-period exchange economy under uncertainty, we find both upper and lower bounds for the risk free interest rate when the agents' utility functions exhibit constant absolute risk aversion. These bounds are independent of the degree of market incompleteness, and so in particular...

This paper studies the factors that can generate the puzzling saving phenomenon in the US: 1) Starr-McCluer (1996) finds that households covered by private health insurance save more than comparable households without coverage, even when controlling for other variables. 2) The asset holding...

This paper provides a tractable continuous-time constant-absolute-risk averse (CARA)-Gaussian framework to quantitatively explore how the preference for robustness (RB) affects the interest rate, the dynamics of consumption and income, and the welfare costs of model uncertainty in general...
