This paper provides an efficiency argument in favour of progressive labour income taxation. When the consumer faces a trade-off between investments in financial and human capital, a proportional comprehensive income tax tends to discriminate in favour of human capital investments. This effect is...

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...

The upcoming one-year repeal of the federal estate tax creates an opportunity to reconsider the taxation of wealth transfers. This paper argues that federal wealth transfer taxes should be retained and potentially expanded. The estate tax contributes importantly to the progressivity of the tax...

This paper characterizes the optimal income taxation when individuals respond along both the intensive and extensive margins. Individuals are heterogeneous in two dimensions: their skills and their disutility of participation. Preferences over consumption and work effort can differ with the...

It comes as no surprise to any observant person in this country that there is a wide disparity in our federal income tax treatment of persons who have differing incomes and financial resources. But while much has been written on tax law complexity and inefficiency, little or nothing has been...

This paper explores the interactions between taxes on work-related traffic congestion and pre-existing distortionary taxes in the labor market. A congestion tax raises the overall costs of commuting to work and discourages labor force participation. The resulting welfare loss in the labor market...

The presence of preexisting tax distortions, and the form of revenue recycling, can crucially affect the size - and possibly even the sign - of the welfare effect of road pricing schemes. The efficiency gains from recycling congestion tax revenues in other tax reductions can amount to several...

This paper examines the choice between revenue-raising and non-revenue-raising instruments for environmental protection in a second-best setting with pre-existing factor taxes. We find that interactions with pre-existing taxes fundamentally influence the costs of regulation and seriously...
