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...

This paper analyzes the effectiveness of the tax and transfer systems in the European Union and the US to act as an automatic stabilizer in the current economic crisis. We find that automatic stabilizers absorb 38 per cent of a proportional income shock in the EU, compared to 32 per cent in the...

This paper reviews the literature on optimal taxation of labour income and the empirical work on labour supply and the elasticity of taxable income in Sweden. It also presents an overview of Swedish taxation of labour income, offers calculations on the development in effective marginal tax rates...

We argue that societies with a stronger tendency towards postmaterialist life goals tilt the tax structure towards personal income taxes and away from corporate taxation. We provide empirical evidence for this correlation in OECD countries. To address endogeneity issues we then use an...

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...
