It is well-known that cash-flow business taxes with full loss-offset, and their present-value equivalents, are neutral with respect to firms' investment decisions when firms are riskneutral and there are no distortions. We study the effects of cash-flow business taxation when there is bankruptcy...

According to a revised definition of Samuelson, a risk-averse agent is called a coward whenever he refuse even a small portion of a risky gamble exhibiting a positive expected payoff. This property may cause the invalidation of some of the basic theorems of the insurance and finance theory. As...

This paper describes the infinite-horizon general equilibrium model that, among other models, CBO uses for its analysis of the President's budgetary proposals. Agents in the model live forever and face uninsurable, individual-specific working-ability shocks and borrowing constraints, and so they...

We study optimal fiscal policy in a standard incomplete-markets model with uninsurable idiosyncratic income risk, where a Ramsey planner chooses time-varying paths of proportional capital and labor income taxes, lump-sum transfers (or taxes), and government debt. We find that: (1) short-run...

I construct a unified macroeconomic framework by incorporating frictional markets in a neoclassical environment. This framework is analytically tractable despite search frictions, income risks and endogenous money distributions. I use this framework to formalize a theory that the variety and the...

In this paper the impacts of income and consumption taxes are analyzed within a model of stochastic endogenous growth with congestion. It is shown that the optimal amount of governmental input diminishes with uncertainty and that the optimal financing depends on the relation between the degrees...
