This paper examines the empirical relevance of the double dividend of revenue neutral marginal environmental tax reforms. For this purpose we use an extended version of the Ahmad-Stern model of indirect taxation. This version includes environmental externalities. We estimate the key parameters...

A digressive tax like a variable rate sales tax or a tax on price gives firms an incentive for expanding output. Thus, unlike unit and ad valorem taxes which amplify the harm from monopoly, a digressive tax lessens the harm. We analyse a tax on price with respect to efficiency and practical...

In this paper, we consider a non-cooperative and symmetric three-stage game model composed by two regulator-firm hierarchies. By means of adequate emission taxes, original and absorptive research and development (R&D) subsidies we prove that regulators can reach the non-cooperative social...

The Ramsey approach to optimal taxation and Ramsey tax rules have amassed substance in economic theory. However, they are often criticized on grounds of practicality, fairness, feasibility and some other aspects of designing actual tax policy. This paper presents a collection of these views; it...

This paper addresses the reduction of market failure under imperfect competition. It proposes a taxscheme that provides firms with an incentive to forgo their market power: Firms optimize after-tax profits. Now simply consider a firm´s gross profit margin the unique tax-rate it is charged on...

Economists traditionally tackle normative problems by computing optimal policy, i.e., the one that maximizes a social welfare function. In practice, however, a succession of marginal changes to a limited number of policy instruments are implemented, until no further improvement is feasible. I...

Differential tax analysis is used to show how the socially optimal fiscal-tax to liquidity-tax ratio changes with the relative size of the tax-evading hidden economy. The smaller the relative size of the hidden economy, the larger the optimal fiscal-tax to liquidity-tax ratio. The empirical...

It has been argued in the literature that, interjurisdictional competition forces the public sector to increase its efficiency and thus helps to tame Leviathan governments. The paper addresses this hypothesis by means of a simple taxcompetition model with a Leviathan state. It is seen that the...

The paper discusses the applicability of optimal taxation theory to source-based capital incomes when significant tax evasion is observed. Without tax evasion a modified Ramsey Rule may reduce distortions brought by international capital mobility, leading to levying differentiated tax rates in...

The European Emissions Trading Scheme for CO2 established in 2005 is the world's largest emissions trading scheme. Since it covers only some sectors of the European economies it can nevertheless not ensure that the Kyoto targets are reached at minimal cost. This paper first analyzes the...
