This paper re-examines the optimal tax design problem (income and commodities) in the presence of externalities. The nature of the second-best, and the choice of the tax instruments, are motivated by the informational structure in the economy. The main results are: (i) environmental levies...

This paper examines the rationale for the different tax treatment of gasoline and diesel cars currently observed in Europe. First, we analyse possible justifications for a different tax treatment: pure tax revenue considerations, externality cons0iderations and constraints on the tax instruments...

We study the optimality of taxing capital income according to a Rate-of-Return Allowance proposed by the Mirrlees Review. In a mean-variance framework the optimal tax on risk-free returns is zero with constant returns to scale in private investment, but positive with decreasing returns to scale,...

We model a dynamic monopoly with environmental externalities,investigating the adoption of a tax levied on the firm's instantaneous contribution to the accumulation of pollution. The latter process is subject to a shock, which is i.i.d. across instants. We prove the existence of an optimal tax...

This paper studies optimal non-linear income taxation in an empirically plausible model with labor supply responses at the intensive (hours, effort) and the extensive (participation) margin. In this model, redistributive taxation gives rise to a previously neglected trade-off between two aspects...

This paper examines regulation in the presence of adjustment costs and resource scarcity, allowing for imperfectly informed firms. I find strong evidence that announcement of future environmental regulation will reduce current emissions in the combined presence of resource scarcity and...

A tax on fuel combined with tax-exemptions or subsidies for purchase of fuel-efficient vehicles is implemented in many countries to reduce greenhouse gas emissions and other negative externalities from road traffic. This study, however, shows that a tax on fuel should be combined with heavier...

The marginal cost of public funds (MCF) is substantial in generous welfare state countries according to Kleven and Kreiner (2006). Their main estimate for the Danish economy exceeds 2 mainly because taxation distorts labor force participation. Adjustments in social transfers which alleviate such...

We analyze a n-country, two-period Nash tax competition game to evaluate Sinn's proposal to use capital income taxation as a means to decelerate fossil fuel ex- traction (Sinn, 2008). The interest and discount rate is determined on a perfectly competitive consumer loan market on which the...

Social disparities have a common and consistent character in the vast majority of contemporary countries. The level of income inequality in OECD countries has grown in the past 30 years and is still rising. Taxes and tax systems, aside from social transfers, are fiscal instruments widely used in...
