This paper analyzes features of perfect taxation – also known as optimal taxation – when one or more private markets is imperfectly competitive. Governments with perfect information and access to lump-sum taxes can provide corrective subsidies that render outcomes efficient in the presence of imperfect competition. Relaxing either of these two conditions removes the government’s ability to supp...

Government budget balance forces the endogenous use of distortionary tax instruments when an exogenous reform is implemented. The aggregate efficiency of such reforms is based on comparisons of simple summary measures of the Marginal Cost of Funds of the various tariff or quota changes with the Marginal Cost of Funds of the alternative taxes, or of the Marginal Benefit of Government supplied go...

This paper focuses on two core tax design issues that arise in addressing current fiscal challenges. It first explores the idea, prominent in troubled Eurozone countries, of a “fiscal devaluation”: shifting from social contributions to the VAT as a way to mimic a nominal devaluation. Empirical evidence is presented which suggests that in Eurozone countries this may indeed improve the trade bala...

The escalation of oil prices in the last years has motivated a debate about natural resources taxation. This paper uses real options approach to discuss different taxation devices for exploration & production (E&P) with focus in Brazilian petroleum sector. The concept of tax neutrality under uncertainty is established when both the project value and investment follows correlated stochastic proc...

We study the political economy of social insurance in a world where individuals di¤er in both income and risk. Social insurance is ...nanced through distortionary taxation and redistributes across income and risk. Individuals vote on social insurance which they can complement with insurance bought on the private market. Private insurance is actuarially fair but su¤ers from adverse selection whi...

This paper offers a first empirical investigation of how labor taxation (income and payroll taxes) affects individuals' well-being. For identification, we exploit exogenous variation in tax rules over time and across demographic groups using 26 years of German panel data. We find that the tax effect on subjective well-being is significant and positive when controlling for income net of taxes. T...

Shifting of income between the corporate and the personal income tax bases in response to tax incentives is the premise of the literature on taxation and organizational form. Empirical evidence of income shifting is, however, merely circumstantial. Using a unique panel of highfrequency VAT data from Israel, we trace the footprints of income-shifting through incorporation by high-income individu...

This paper shows how a popular system of federal revenue equalization grants can limit tax competition among subnational governments, correct fiscal externalities, and increase government spending. Remarkably, an equalization grant can implement efficient policy choices by regional governments, regardless of a wide variety of differences in regional tax capacity, tastes for public spending, and...
