Recurrent intervals of inattention to the stock market are optimal if consumers incur a utility cost to observe asset values. When consumers observe the value of their wealth, they decide whether to transfer funds between a transactions account from which consumption must be financed and an...

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...

Although the Ricardian Equivalence Theorem holds under a linear estate tax schedule, it fails to hold under a nonlinear estate tax schedule. In a representative consumer economy, a temporary lump-sum tax increase reduces contemporaneous consumption. If different consumers face different marginal...

Various tax policies provide consumers with forms of insurance. Social security has the payoff characteristics of an annuity. The income tax provides consumers with a degree of Income insurance because the government shares part of the individual's income risk. Redistributive taxes can be used...

This paper extends the theory of investment under uncertainty to incorporate fixed costs of investment, a wedge between the purchase price and sale price of capital, and potential irreversibility of investment. In this extended framework, investment is a non-decreasing function of q, the shadow...

This paper analyzes the dynamic behavior of capital accumulationin Stockman's (1981) cash-in-advance model. If the cash-in-advance constraint applies only to consuittion, then money is superneutral along the transition path as well as in the long run. Alternatively, if the cash-in-advance...

The issue of dynamic efficiency is central to analyses of capital accumulation and economic growth. Yet the question of what operating characteristics of an economy subject to productivity shocks should be examined to determine whether or not it is efficient has not been resolved. This paper...

This paper presents an overview of current models of consumption and investment behavior. First, the stochastic implications of the permanent income model and empirical tests of these implications are discussed. Then the simple theoretical model is extended to include expenditure on consumer...
