With fixed costs of participating in the stock market, consumers with high income will participate in the stock market, but consumers with lower income will not participate. If a fully-funded defined-contribution social security system tries to exploit the equity premium by selling a dollar of...

For a firm that cannot raise external funds, cash on hand serves as precautionary saving. We derive a closed-form expression for the target level of cash on hand in the presence of persistent cash flows. Contrary to conventional wisdom, a mean-preserving increase in the volatility of cash flow...

Social policy to limit interactions can slow the spread of infection, but this benefit comes at the cost of reduced output. We solve an optimal control problem to choose the degree of interaction to maximize an objective function that rewards output and penalizes excess deaths. Optimal policy...

A financial constraint that prevents access to external funds induces non-classical measurement error in average q as a proxy for unobservable marginal q. Unlike classical measurement error, this measurement error biases upward the coefficient on average q in a univariate regression of...

Government debt can be rolled over forever without primary surpluses in some stochastic economies, including some economies that are dynamically efficient. In an overlapping-generations model with constant growth rate, g, of labor-augmenting productivity, and with shocks to the durability of...

We characterize a planner's optimal allocation of consumption and capital in an overlapping generations model with exogenous government purchases, privately-observed idiosyncratic shocks to the depreciation rate of capital, and a proportional cost of reversing investment to transform used...

This paper explores the current tax treatment of non-qualified immediate annuities and distributions from tax-qualified retirement plans in the United States. First, we describe how immediate annuities held outside retirement accounts are taxed. We conclude that the current income tax treatment...

This paper analyzes the joy of giving bequest motive in which the utility obtained from leaving a bequest depends only on the size of the bequest. It exploits the fact that this formulation can be interpreted as a reduced form of an altruistic bequest motive to derive a relation between the...

This paper presents a calculation of the time series of the after-tax rate of return to whole life insurancy. When compared to the after-tax return on an alternative portfolio of similar risk, more than 60%of the decline in life insurance savings (suitably defined) in the past two decades can be...

The observed reluctance of most individuals in the United States to buy individual life annuities, and the concomitant approximately flat average age-wealth profile, stand in sharp contradiction to the standard life cycle model of consumption-saving behavior. The analysis in this paper lends...
