La tasa óptima de impuesto a los ingresos de capital en Estados Unidos es 36% según Conesa y otros (2009). Este resultado se deriva de un modelo de ciclo de vida y se debe a la existencia de mercado incompletos y a la oferta laboral endógena. Se muestra que este modelo tiene problemas en...

In a two-type Stiglitz (1982) model of optimal non-linear taxation it is shown that when the utility function relating to consumption is logaritmic the shadow price of the incentive constraint relating to the optimal tax problem exactly equals the Gini coefficient of the secondbest optimal...

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

This paper presents the properties of optimal piecewise linear tax systems for two-earner households, based on joint and individual incomes respectively. A key contribution is the analysis of the interaction between second earner wage differences, variation in the price of child care and...

Relative consumption effects or status concerns that feature jealousy (in the sense of Dupor and Liu, AER 2003) boost consumption expenditure. If consumption is financed by labour income, such status considerations increase labour supply and, hence, the tax base. A higher taxable income, in...

In 2009 a flat tax reform was implemented in the Kyrgyz Re public following similar reforms in neighbor countries and efficiency reasons. This paper discusses problems in the Kyrgyz personal income taxation arising after the reform, when progressive income tax rates were changed to a flat rate....

We compute the optimal non-linear tax policy for a dynastic economy with uninsurable risk, where generations are linked by dynastic wealth accumulation and correlated incomes. Unlike earlier studies, we take full account of the welfare distribution along the transition to the new steady state...

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 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...
