In this article we write a two period taxation model where: \QTR{it}{i)} private information changes through time; \QTR{it}{ii)} savings choices by an agent that are not observed, \QTR{it}{iii)} affect preferences conditional on the realization of types. The simultaneous appearance of these three...

This paper is motivated by a practical income (or wealth) taxation problem: For a public good economy where the provision of public goods is to be financed by income taxes collected from individuals, what is the optimal feasible tax mechanism when a social planner is relatively uninformed of the...

This paper describes the behavior of tax policies under incomplete financial markets. The government finances a stochastic stream of expenditures by collecting the capital income and the labor income taxes, and issuing a one-period bond which pays state-contingent returns. We show that putting...

We build a theoretical model to study whether a minimum wage can be welfare-improving if it is implemented in conjunction with an optimized nonlinear income tax. We consider this issue in a framework where search frictions on the labor market generate unemployment. Workers differ in...

In a two-period world with endogenous savings and two assets, the optimal tax structure and optimal diversification of aggregate (capital) risk between private and public consumption are analyzed. We show that there is no trade-off between efficiency in intertemporal consumption and allocation...

We study experimentally how taxpayers choose between two tax regimes to fund a public good. The first-best tax regime imposes a general, distorsion-free income tax. However, this tax cannot be enforced. The second-best alternative supplements the income tax by a specific commodity tax. This tax...

This paper analyses the optimal tax policy and public provision of private goods when individuals differ in two respects: income-earning ability and rationality. Publicly provided goods should be overprovided or subsidised, relative to the decentralised optimum, if society’s marginal valuation...
