In this paper, we conduct a theoretical analysis of the consumption and income taxes from the viewpoints of efficiency and equity, we evaluate the past and present structure of Japan's consumption and income taxes, we consider the role of the consumption tax in stimulating the economy, in...

This articles studies the optimal tax mix (taxes on income and commodities) under asymmetric information in a two-type model, when individuals make relative consumption comparisons. The model includes both positional and nonpositional goods, taking into account the fact that relative concerns...

This article incorporates tax evasion into an optimum taxation framework with individuals differing in earning abilities and initial wealth. We find that despite the possibility of its evasion a tax on initial wealth should supplement the optimal nonlinear income tax, given a positive...

This paper extends the previous literature on optimal redistributive taxation in the presence of externalities to a multi-externality setting. While taxes on income and on 'clean' commodities are still unaffected by the externalities, which confirms previous results, I find that the existence of...

In this paper we show that in a two sector economy with heterogeneous agents and competitive markets, in a steady state the optimal capital income tax rate is in general different from zero. The optimal tax policy in this setting depends on the relative price difference. In a two sector economy...

We consider a model of prejudice-driven discrimination, where the advantaged 'tall' discriminate against the disadvantaged 'short'. We employ an egalitarian social welfare function to compare anti-discrimination legal rules with a non-discriminatory ('height-blind') income tax.

Should a redistributive government optimally subsidize education to provoke a reduction in the skill premium through general equilibrium effects on wages? To answer this question, this paper studies optimal linear and non-linear redistributive income taxes and education subsidies in two-type...

Gender Based Taxation (GBT) satisfies Ramsey's optimal criterion by taxing less the more elastic labor supply of (married) women. This holds when different elasticities between men and women are taken as exogenous and primitive. But in this paper we also explore differences in gender...

This paper studies second-best policies in an OLG model in which endogenous growth results from human capital accumulation. When young, individuals decide on education, saving, and nonqualified labour. When old, individuals supply qualified labour. Growth equilibria are inefficient in...

We study how an optimal income tax and an optimal public-goods provision rule respond to preference and productivity shocks. A conventional Mirrleesian treatment is shown to provoke manipulations of the policy mechanism by individuals with similar interests. We therefore extend the Mirrleesian...
