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 study examines how tax system design and reform affect labor supply. We conduct an online experiment with 522 participants to assess labor responses to tax reforms that introduce or remove a notch, affecting after-tax income at either the lower or upper end of the income distribution. Our...

Unintended consequences of a pre-announced climate policy have been studied in a variety of situations. We show that early announcement of a carbon tax gives rise to a "Green-Paradox", in that it increases polluting emissions in the interim period (between announcement and actual...

We provide quasi-experimental evidence on the income tax-induced migration of foreign high-income households living in Switzerland by exploiting the differential tax treatment of UK and US households. While the two groups are similar in terms of non-tax sorting preferences, US households are...

This paper studies the design of tax systems that implement a planner's second-best allocation in a market economy. An example shows that the widely used Mirrleesian (1976) tax system cannot implement all incentive-compatible allocations. Hammond's (1979) "principle of taxation" proves that any...

We characterize the second-best allocation in a Mirrleesian optimal tax model where agents differ in multiple dimensions and the planner can tax multiple goods non-linearly. We develop a new method that allows us to solve the partial differential equations that describe the optimum regardless of...

It is entirely appropriate that the study of public finance take seriously "behavioralʺ inconsistencies with traditional models of individual and collective decision-making. This raises the question of whether the state should play a role in protecting individuals from themselves, and whether...

We augment a standard tax model by concerns about tax equity: people get upset when labour is taxed more heavily than capital. Even the slightest concern for tax equity invalidates the common recommendation for small open economies that capital should remain tax-exempt. This holds for exogenous...
