This paper computes the optimal progressivity of the income tax code in a dynamic general equilibrium model with household heterogeneity in which uninsurable labor productivity risk gives rise to a nontrivial income and wealth distribution. A progressive tax system serves as a partial substitute...

This paper studies the macroeconomic effects of implicit government guarantees of the obligations of government-sponsored enterprises. We construct a model with competitive housing and mortgage markets in which the government provides banks with insurance against aggregate shocks to mortgage...

This paper studies the role of intangible capital investment in the timing of optimal capital income tax reforms. Within an infinitely lived worker-capitalist model as in Judd (J Public Econ 28:59-83, 1985), we consider two different economies: one in which capitalists devote physical...

We examine the optimal policy response to an exogenously given demographic shock. Such a shock affects negatively the financing of retirement pensions, and we use optimal fiscal policy in order to determine the optimal strategy of the social security administration. Our approach provides...

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...

This paper studies the effect of demographic transitions on the economy of Latin America and the Caribbean (LAC). The paper builds a model of multi-regions of the world and derives the path of macroeconomic variables including aggregate output, capital, labor and the saving rate as economies...

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....

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...
