The discussion about income versus consumption as the ideal tax base looks back on a long history. In recent years, the debate about income versus consumption as the better tax base reemerged in the United States (2002) and in Germany (2006). In view of the long history of the debate, it is...

Unilateral climate policy induces carbon leakage through the relocation of emission-intensive and trade-exposed industries to regions with no or more lenient emission regulation. Both analytical and numerical studies suggest that emission pricing combined with border carbon adjustments may be a...

We show in a two-period world with endogenous savings and two assets, one of them exhibiting a stochastic return that an interest adjusted income tax is optimal. This tax leaves a safe component of interest income tax free and taxes the excess return with a special tax rate. There is no trade...

We study the optimal tax system in a dynamic model where differences in wages induce differences in inheritances, and the transition from parent ability to child ability is described by a Markov chain. We characterize expected inheritances in the steady state and show that the Atkinson-Stiglitz...

In this paper, we conduct a theoretical analysis of personal taxes (defined to include consumption and income taxes), describe and evaluate the past and present structure of personal taxes in Japan, and based on our findings, make a number of policy recommendations about how to reform personal...
