This paper investigates optimal airport pricing when airlines provide imperfect substitutes products, and make decisions on capacity, scheduling and pricing. We show that the first-best toll per flight may be higher than the simple market-shares formulae that were recently derived for Cournot...

Using a general equilibrium model with heterogeneous waste, this paper studies optimal waste policy when households have to exert separation effort to produce near-homogeneous waste streams suitable for recycling. Our model explicitly allows for changes in the composition (quality) of waste...

We study optimal linear income taxation in a model with heterogeneous agents where earnings potentials are endogenously determined through human capital accumulation. Agents differ in initial conditions and ability to learn. Capital market imperfections prevent poor agents to invest optimally in...

This paper investigates second-best congestion pricing in a monocentric city characterized by distortionary, rigid regulatory mechanisms in the housing market (building height restrictions, zoning and property taxation). The Pigouvian toll is shown to retain its optimality under any setting with...

This paper studies the design of tax systems that implement a planner's second-best allocation in a market economy. An example shows that the widely used Mirrleesian (1976) tax system cannot implement all incentive-compatible allocations. Hammond's (1979) "principle of taxation" proves that any...

We consider equilibrium and optimum use of a Vickrey road bottleneck, distinguishing between long-run and short-run scheduling preferences in an otherwise stylized scheduling model. The preference structure reflects that there is a distinction between the (exogenous) 'long-run preferred arrival...

The European Commission favours the introduction of a consolidated corporate tax base to overcome the distortions arising from the existing system of separate accounting. The blueprints for consolidation are simulated with the applied general equilibrium model CORTAX. We show that the benefits...

We argue that promoting education may be a means to reduceincome inequality. When workers of different skill levels areimperfect substitutes in production, an increase in the level ofhuman capital in the economy reduces the return to education.Hence, a given compression of after-tax incomes can...

The paper addresses two related issues: the optimal intergenerational sharing of laborproductivity risks, through a Pay-As-You-Go (PAYG) social security, and the mix ofPAYG and savings for retirement provision in a small open economy. It shows that <I>partial</I> contingency of the social security on...</i>

We apply theories of capital market failure to ana1yzeoptima1 financing of risky higher education. In the market solution,students can only finance their education through debt. There isunderinvestment in human capita1, because some students with socia1lyprofitable investments in human capita1...
