The present study provides estimates of the Effective Marginal Tax Rates (EMTRs) for a sample of 17 OECD countries and 11 manufacturing sectors in a single framework encompassing capital, labour and energy taxes. Our cross-country/cross-sector approach allows us comparing the incentives provided...

This paper examines the effective tax rates faced by low income working families. The effective tax rate (ETR) is a generic concept which encompasses both tax payable and also loss of benefits as income rises.

Economists traditionally tackle normative problems by computing optimal policy, ie the one that maximizes a social welfare function. In practice, however, a succession of marginal changes to a limited number of policy instruments are implemented, until no further improvement is feasible. I call...

The tax policy agenda in Australia for more than a decade has been largely driven by a perceived need to reduce the level of income taxation and the progression of marginal rates, financing the revenue shortfall with a broad based consumption tax. A major reform of this kind is now being...

This Paper explores the optimal role of the tax system in alleviating labour-market imperfections and raising revenue. For this purpose, the standard search model of the labour market is extended by introducing scarce entrepreneurial talent and arbitrage between the supply and demand. We study...

There is often a gap between the prescriptions of an "optimal" tax system and actual tax systems, some of which can be neither efficient economically nor efficient at redistributing income. With a focus on personal income taxes, this paper reviews the political economics literature on tax...

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...

We examine the interaction between commodity taxes and parallel imports in a simple two-country model with imperfect competition. While governments determine non-cooperatively their commodity tax rate, the volume of parallel imports is determined endogenously by the retailing sector. We compare...

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

This paper presents for the .rst time the properties of optimal piece-wise linear tax systems for two-earner households, based on joint and individual incomes respectively. A key contribution is the analysis of the interaction of second earner wage di¤erences, variation in prices of bought-in...
