This paper develops a model of search on the labour market with training. The model reveals how the tax system can restore the social optimum if the Hosios condition is not satisfied in the private equilibrium. Furthermore, the effects are explored of a second-best reform from average to...

The standard tax theory result that investment should not be distorted is based on the assumption that profits are locally bound. In this paper we analyze the optimal tax policy when firms are internationally mobile. We show that the optimal policy response to increasing firm mobility may be...

In economies with competitive labour markets social policies harm employment and output. In Europe, in particular, non-competitive labour markets with trade unions, efficiency wages and/or costly search and mismatch seem more realistic. Social policies such as progressive taxation or...

We analyse the question of optimal taxation in a dual economy, when the government is concerned about the distribution of labour income. Income inequality is caused by the presence of sunk capital investments, which creates a 'good jobs' sector due to the capture of quasi-rents by trade unions....

In exploring the impact of tax policy on labor-market performance, the paper first investigates how tax reform impacts labor supply and equilibrium unemployment in representative agent models. The impact of tax policy on labor market performance depends importantly on various other labor-market...

This paper analyzes the design of optimal unemployment insurance in a search equilibrium framework where search eÞort among the unemployed is not perfectly observable. We examine to what extent the optimal policy involves monitoring of search effort and benefit sanctions if observed search is...

This paper considers an optimal income tax cum higher education policy. It shows that in the presence of an optimal income tax system higher education should be taxed rather than subsidized. Furthermore, income taxes should become less progressive when an optimal higher education policy is...

This paper provides an efficiency argument in favour of progressive labour income taxation. When the consumer faces a trade-off between investments in financial and human capital, a proportional comprehensive income tax tends to discriminate in favour of human capital investments. This effect is...

Compared with the traditional public-finance approach of a monolithic fully informed planner, earmarking of taxation is less likely to be optimal if a principal-agent setting is considered, where taxing and spending are performed by two separate agents which are monitored by the parliament. We...

According to conventional wisdom internationally mobile capital should not be taxed or should be taxed at a lower rate than labour. An important underlying assumption behind this view is that there are no market imperfections, in particular that labour markets clear competitively. At least for...
