Extensive research has shown that few robust results regarding the optimal tax structure are available. Moreover, the stylised models used in optimal tax analyses are not appropriate for practical policy advice. This paper proposes a method of examining optimal marginal income tax reforms using...

In a number of high-income countries over the past few decades there has been a large growth in income inequality and at the same time a shift in the burden of taxation from the top to the middle of the income distribution. This paper applies the theory of optimal piecewise linear taxation to...

We give an objective meaning to the concept of taxable capacity and establish a theoretical link between Optimal Taxation Theory (OTT) and the proposals of the Carter and Meade Reports, solving at the same time Kay’s (2008) criticism to both approaches.

Effective from 2005, benefits for long-term unemployed have been reduced in Germany to the level of social assistance. This measure reflects the view that "all who are able to work, should work" - a view which makes sense only if the government can distinguish the disabled from the productive....

In a two-type Stiglitz (1982) model of optimal non-linear taxation it is shown that when the utility function relating to consumption is logaritmic the shadow price of the incentive constraint relating to the optimal tax problem exactly equals the Gini coefficient of the secondbest optimal...

We consider an economy where individuals face uninsurable risks to their human capital accumulation, and study the problem of determining the optimal level of linear taxes on capital and labor income together with the optimal path of the debt level. We show both analytically and numerically that...

We characterize the solution to the optimal nonlinear income taxation problem if individuals face a minimum hours constraint that gives rise to labor supply responses along the extensive margin. We provide conditions for optimal marginal tax rates to be positive everywhere and derive a formula...

In 2009 a flat tax reform was implemented in the Kyrgyz Re public following similar reforms in neighbor countries and efficiency reasons. This paper discusses problems in the Kyrgyz personal income taxation arising after the reform, when progressive income tax rates were changed to a flat rate....

Most European countries suffer from a structural weakness of employment and competitiveness. Can an optimal tax system reinforce European countries in this respect? If so, does this long-term policy act as a devaluation or a revaluation? In this paper, we show that fiscal devaluation can be an...

We compute the optimal non-linear tax policy for a dynastic economy with uninsurable risk, where generations are linked by dynastic wealth accumulation and correlated incomes. Unlike earlier studies, we take full account of the welfare distribution along the transition to the new steady state...
