In this paper we quantitatively characterize the optimal capital and labor income tax in an overlapping generations model with idiosyncratic, uninsurable income shocks, where households also differ permanently with respect to their ability to generate income. The welfare criterion we employ is...

This paper quantifies the effects of two short-run fiscal policies, a temporary tax cut and a temporary rebate transfer, that are intended to stimulate economic activity. A reduction in income taxation provides immediate incentives to work and save more, raising aggregate output and consumption....

The U.S. tax policy on health insurance is regressive because it favors only those offered group insurance through their employers, who tend to have a relatively high income. Moreover, the subsidy takes the form of deductions from the progressive income tax system, giving high-income earners a...

The U.S. tax policy on health insurance favors only those offered a group insurance through their employers. This policy is highly regressive since the subsidy takes the form of deductions from the progressive tax system. The paper investigates alternatives to the current policy. We find that...

We explore the welfare consequences of different taxation schemes in an economy where agents are debt-constrained. If agents default on their debt, they are banned from future credit markets, but retain their private endowments which are subject to income taxation. A change in the tax system...

How much additional tax revenue can the government generate by increasing the level of labor income taxes? In this paper we argue that the degree of tax progressivity is a quantitatively important determinant of the answer to this question. To make this point we develop a large scale overlapping...

This paper proposes a simple mechanism of capital taxation that is negatively correlated with labor supply. Using a life-cycle model of heterogeneous agents, I show that this tax scheme provides a strong work incentive when households possess large assets and high productivity later in the life...

In this paper we characterize quantitativelya the optimal mix of progressive income taxes and education subsidies in a model with endogeneous himan capital formation, borrowing constraints, income risk and incomplete financial markets. Progressive labor income taxes provide social insurance...

This paper quantifies the effects of two short-run fiscal policies, a temporary tax cut and a temporary rebate transfer, that are intended to stimulate economic activity. A reduction in income taxation provides immediate incentives to work and save more, raising aggregate output and consumption....

In this paper we argue that very high marginal labor income tax rates are an effective tool for social insurance even when households have preferences with high labor supply elasticity, make dynamic savings decisions, and policies have general equilibrium effects. To make this point we construct...
