This paper presents an approach for the estimation of welfare effects of tax policy changes under heterogeneity in consumer preferences. The approach is applied to evaluate the welfare effects of current tax advantages for electric vehicles supplied as fringe benefits by employers. Drawing on...

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...

We estimate the impact on health care utilization and out-of-pocket (OOP) expenditures of a major reform in Thailand that extended health insurance to one-quarter of the population to achieve universal coverage while keeping health spending below 4% of GDP. Identification is through comparison...

Much attention has been paid to the influence of the institutional form of waste collection on costs. We extend this literature in three directions by including the unit-based pricing system. First, we show that unit-based pricing systems are more important from a cost-minimizing point of view...
