We analyse the question of optimal taxation in a dual economy, when the policy-maker 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...

This Paper analyses the optimal timing of taxes on capital income. We show that the celebrated result that taxes should front-loaded with an initially high tax followed by a discrete jump to the steady state is knife-edge, hinging on capital having a constant depreciation rate. An empirically...

In the coming decades, the share of people in working age will fall significantly in most developed countries. According to optimal taxation theory, public debts should be reduced before the baby-boom generation retires. I find that if debts are instead maintained at the current levels, welfare...

We completely characterize the set of second-best optimal "menus" of student-loan contracts in a simple economy with risky labour-market outcomes, adverse selection, moral hazard and risk aversion. The model combines structured student loans and an elementary optimal income-tax problem à la...

We characterize optimal redistribution in a dynastic family model with human capital. We show how a government can improve the trade-off between equality and incentives by changing the amount of observable human capital. We provide an intuitive decomposition for the wedge between human-capital...

The implications of more environmental concern for the optimal provision of public goods, taxation, environmental policy and involuntary unemployment are derived within a second-best framework in which lump-sum taxes and subsidies are not available and labour supply is rationed due to a rigid...

The answer to this question is "yes". We re-examine noncooperative and cooperative equilibria under perfect capital mobility. To this end, we develop a two-country optimal growth model with endogenous national fiscal policies. The channel for interdependence is distortionary income taxes. We...

In this Paper, we take the field of optimal dynamic taxation further in two directions. Using a model with invisible labour, as in Hansen (1986) and Rogerson (1988), we first explore the short-run dynamics of the capital-income tax, particularly whether the tax, under the second-best programme,...

Gender Based Taxation (GBT) satisfies Ramsey’s optimal criterion by taxing less the more elastic labour supply of (married) women. This holds when different elasticities between men and women are taken as exogenous and primitive. But in this paper we also explore differences in gender...

This paper analyses optimum income taxation in a model with endogenous job destruction that gives rise to unemployment. It is shown that optimal tax schemes comprise both payroll and layoff taxes when the state provides public unemployment insurance and aims at redistributing income. The optimal...
