Why is it optimal not to tax capital income in the long-run in Chamley (1986) and Judd (1985)? This paper demonstrates that the answer follows standard intuitions from the commodity tax literature. In the steady state, Engel curves for consumption are linear in labour earnings, irrespective of...

Finland is committed to high quality and extensive public services and a high level of income redistribution. The heavy tax burden these commitments require is becoming increasingly difficult to sustain due to tax competition and the need to harmonise certain taxes with other EU countries. These...

We analyse an equilibrium labour market with on-the-job search and experience effects (where workers learn-by-doing). The analysis yields a standard Mincer wage equation with worker fixed effects and endogenously determined firm fixed effects. It shows that learning-by-doing increases...

We analyze an equilibrium labor market with on‐the‐job search and experience effects (as workers learn by doing). The analysis yields a Mincer wage equation with worker fixed effects and endogenously determined firm fixed effects. Equilibrium sorting - where over time more experienced...

We study fiscal devaluation in a small-open economy with labor market search frictions. Our analysis shows the key role of both dimensions in shaping the optimal tax scheme. By reducing labor market distortions, the tax reform is welfare-improving. Yet, as it makes imports more expensive, fiscal...

This dissertation is a contribution to the theoretical foundation of optimal tax codes in models with human capital formation. From the economic point of view, a tax system should generate the government’s required revenue with as little economic distortion as possible. In the literature this...
