I focus on one of the most-commonly-cited 'facts'; about UK income inequality â that it has changed little over the last 30 years â and reflect on how robust that description is. I look at a number of fundamental issues in inequality measurement related to inequality concepts (e.g., inequality...

Tax Liability Side Equivalence (tax LSE) claims that the statutory incidence of a tax is irrelevant for its economic incidence. In gift-exchange labor markets, firms provide a gift to workers by paying high wages, and workers reciprocate by providing high efforts. Tax LSE is theoretically...

This paper studies the design of tax systems that implement a planner's second-best allocation in a market economy. An example shows that the widely used Mirrleesian (1976) tax system cannot implement all incentive-compatible allocations. Hammond's (1979) "principle of taxation" proves that any...

What are the impacts of labor tax reform on wage setting and employment to keep the relative tax burden per low-skilled and high-skilled workers constant in the case of heterogeneous domestic labor markets, i.e. imperfect competition in low-skilled labor and perfect competition in high-skilled...

We examine the extent to which taxes on corporate income are directly shifted onto the workforce. We use data on 55,082 companies located in nine European countries over the period 1996-2003. We identify this direct shifting through cross-company variation in tax liabilities, conditional on...

Within an efficiency wage framework, we study the effects of two revenue-neutral tax reforms that change the progressivity of the labour tax system. A revenue-neutral increase in both the wage tax and tax exemption and a revenue-neutral change in the composition of labour taxation towards the...

We show that taxation of rents may yield an intergenerational Pareto-improvement in a small open economy provided tax revenues are earmarked to reduce wage taxes. Previous literature has shown that rent taxation benefits current young and future generations, while we show that it also benefits...

We study the effects of revenue-neutral labor tax reforms in an imperfectly competitive domestic labor market under Nash wage bargaining and flexible outsourcing. A revenue-neutral increase in the wage tax progression will decrease the negotiated wage rate, increase domestic labor demand and...

The Atkinson-Stiglitz Theorem and its extensions have been interpreted as implying that capital income should not be taxed. If, as seems reasonable on empirical grounds, we introduce production of household goods with close market substitutes, this conclusion no longer holds. We analyse optimal...
