Competitive pressure on some capital income tax rates reinforces a generic quadrilemma or a four-way tradeoff in domestic income taxation. To maintain competitiveness, governments have to cut some tax rates on capital income down to international standards. If these cuts lead to a de-alignment...

Under the Nordic dual income tax system, the taxpayer's total tax bill depends not only on his total income but also on the division of that income between capital income and labor income. This has created new room for tax avoidance, especially for active owners of (closed) corporations. For...

We develop models of optimal linear and non-linear income taxation with endogenous human capital formation to explore optimal education subsidies. Optimal subsidies on education ensure efficiency in human capital accumulation and thus play an important role in alleviating the tax distortions on...

This paper proposes a growth-oriented dual-income tax by combining an allowance for corporate equity with a broadly defined flat tax on personal capital income. Revenue losses are compensated by an increase in the value added tax. The paper demonstrates the neutrality properties of the reform...

Pension benefit rules depend on individual history far more than taxes do, and age plays a much larger role in pension determination than in tax determination. Apart from some simulation studies, theoretical studies of optimal tax design typically contain neither a mandatory pension system nor...

Identifying the effect of differential taxation on portfolio allocation requires exogenous variation in marginal tax rates. Marginal tax rates vary with income, but income surely affects portfolio choice directly. In systems of individual taxation - like Canada's - couples with the same...

This paper presents the case for tax progressivity based on recent results in optimal tax theory. We consider the optimal progressivity of earnings taxation and whether capital income should be taxed. We critically discuss the academic research on these topics and when and how the results can be...
