We analyze the role of optimal income taxation across different local labor markets. Should labor in large cities be taxed differently than in small cities? We find that a planner who needs to raise revenue and is constrained by free mobility of labor across cities does not choose equal taxes...

Equilibria and optima generally differ in imperfectly competitive markets. While this is well understood theoretically, it is unclear how large the welfare distortions are in the aggregate economy. Do they matter quantitatively? To answer this question, we develop a multi-sector monopolistic...

This paper analyzes the effect of skill heterogeneity on regional patterns of production and housing in the presence of pecuniary externalities within a general-equilibrium framework, assuming monopolistic competition in intermediate goods markets. It shows that the interplay of heterogeneous...

Germany like many other European countries subsidize commuting by granting the right to deduct commuting expenses from the income tax base. This regulation has often been changed and has regularly been under debate during the last decades. The pros (e.g. causing efficiency gains with respect to...

Although the Computable General Equilibrium (CGE) model is not a new tool for analysing policy impacts, it has not gained a wide popularity in regional applications such as rural economies yet. This study demonstrates how a regional CGE model can be applied for analysing regional impacts of...
