By constructing a social welfare function that incorporates the explicit value judgments of Atkinson's measure of inequality, the paper develops implications of optimal income taxation derived using double limit analysis for transfers and inequality. The losses arising from transfers in the...

This paper augments the theory of optimal linear income taxation by taking into account human capital accumulation as a dimension of labor supply. The distribution of earnings potentials endogenous, because agents differ in ability to learn. Taxation affects utilization rates of human capital as...

This paper examines the distributional outcomes of the tax parameters of the Australian income tax system within the framework of modern tax theory. The analysis focuses first on the parameters of the Personal Income Tax and Low Income Tax Offset. The results show that Australia has moved...

In this report, we combine theory and empirical estimates for how labor earnings respond to changes in tax rates and unearned income. We use lottery winnings to obtain variation in unearned income and tax reforms to obtain variation in the net of tax rate. Combining this information with...

We develop a model for determining the optimal high income linear tax rate when there exist imperfectly substitutable types of labor. If one type is disproportionately prevalent among higher income taxpayers, then wages adjust in response to more progressive taxation and part of the statutory...

In this paper we develop a discrete model of optimal taxation of married couples and empirically discuss the optimality of income taxation for this group. To this end, we derive the social welfare function which guarantees that joint taxation of married couples is optimal. We will contrast this...

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...

In order to explain the joint fluctuations of output, inflation and the labor market, this paper first develops a general equilibrium model that integrates a theory of equilibrium unemployment into a monetary model with nominal price rigidities. Then, it estimates a set of structural parameters...

This paper studies the optimal commodity taxation problem when time taken in consumption is a perfect substitute for either labor or leisure. It shows that while labor substitutability affects the optimal tax structure, leisure substitutability leaves the classical optimal tax results intact. In...
