| Abstract: | Unemployment is a central policy issue in countries with a “generous” welfare system that is hard to reform. This paper addresses why these countries tend to adopt high commodity tax rates in the optimal taxation context. We explore the role of commodity taxation in alleviating moral hazard and hence involuntary unemployment and then provide supportive evidence from a quantitative analysis. Unlike the usual full employment models, at the heart of this paper is a new dimension of distortion, the “between‐states” (employment state vs. unemployment state) consumption choice distortion, which can be dealt with by a certain optimal combination of commodity and income taxation. Our results therefore offer an explanation for the widely observed coexistence of direct and indirect taxation. (JEL D61, D81, H21) |
