This paper tries to clear the confusion in the literature about the potential of environmental tax reforms to yield a double dividend. In opposition to a number of recent papers it is found that the possibility for a double dividend depends largely on the substitutabllity characteristics of...

This paper introduces an index of tax optimality that measures the distance of a current tax structure from the optimal tax structure in the presence of public goods. In doing so, we derive a [0, 1] number that reveals immediately how far the current tax configuration is from the optimal one...

In der wissenschaftlichen Debatte über ein gerechtes und effizientes Steuersystem wird die steuerliche Behandlung von Kapitalerträgen kontrovers diskutiert. Dabei spielt die Höhe der Steuerbelastung der Zinseinkünfte eine wichtige Rolle. Hannes Schellhorn setzt sich hier mit entsprechenden...

Taxation theory rarely takes entrepreneurship into consideration. We discuss how this omission affects conclusions derived from standard models of capital taxation when applied to entrepreneurial income. Some of the defining features of entrepreneurship often omitted by standard capital taxation...

We analyze tax competition between large and asymmetric countries and derive conditions under which countries assist foreign authorities in collecting tax revenues via information exchange. It turns out that voluntary exchange of information is a Nash equilibrium between asymmetric countries,...

This paper introduces an index of tax optimality that measures the distance of some current tax structure from the optimal tax structure in the presence of public goods. In doing so, we derive a [0,1] number that reveals immediately how far the current tax configuration is from the optimal one...

A Norwegian tax reform committee recently proposed a personal tax on the realized income from shares after deduction for an imputed risk-free rate of return. This paper describes the design of the proposed shareholder income tax and shows that it will be approximately neutral in several...

The theory of optimal taxation has often been criticized for being of little practical policy relevance, due to a lack of robust theoretical results. This paper argues that recent advances in optimal tax theory has made that theory easier to apply and may help to explain some current trends in...

The Atkinson-Stiglitz Theorem states that if labor is weakly separable from goods in household utility functions, differential commodity taxation should not be not part of an optimal redistributive tax system. This Theorem, which is arguable the most policy-relevant result to come out of the...
