This paper contributes to resolving the puzzle that in practice most countries use ad valorem (corporate income) taxation, while a large part of the tax competition literature views business taxes as unit (wealth) taxation. We point to the dual role that corporate taxation plays in attracting...

Empirical studies show that job search behavior depends on the financial situation of the unemployed. Starting from this observation, we ask how unemployment insurance policy should take the individual financial situation into account. We use a quantitative model with a realistically calibrated...

We study a matching model with heterogenous agents, nontransferable utility and search frictions. Agents differ along a continuous horizontal dimension (e.g. taste) and a discrete vertical dimension, e.g. income. All individuals prefer the highest type along the vertical trait, but have...

I study a two-period model of nonlinear, information constrained income taxation. It is shown that time-consistent taxation of annual income welfare-dominates time-consistent taxation of lifetime income if preferences are such that stationary allocations are efficient. If uncertainty is taken...

This paper employs a two-period life-cycle model to derive the optimal tax policy when educational investments are subject to endogenous credit constraints. Credit constraints arise from the limited commitment of creditors to repay loans and from the moral hazard problem due to private...

This paper analyzes optimal linear taxes on labor income and savings in a standard two-period life-cycle model with endogenous leisure demands in both periods and non-insurable income risks. Households are subject to skill shocks in both periods of the life-cycle. We allow for completely general...

This paper analyzes tax competition theory in an experimental setting. Economically trained students act as government and must select a labor and a capital tax rate to fund a public good, both in closed and open economy settings. Several results emerge: i) There is only weak evidence that...
