We investigate how potential tax-driven migrations modify the Mirrlees income tax schedule when two countries play Nash. The social objective is the maximin and preferences are quasilinear in consumption. Individuals differ both in skills and migration costs, which are continuously distributed....

We 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 student loans with an elementary optimal income-tax problem. The second-best optima...

This study examines the effect of the device that allows so-called "Scellier" tax benefits when buying housing for rent. We use counterfactual analysis and the fact that the provision applies only in certain areas to assess the impact of the scheme on land prices. Our estimation method uses...
