We estimate the marginal external congestion cost of motor-vehicle travel for Rome, Italy, using a methodology that accounts for hypercongestion (a situation where congestion decreases a road’s throughput). We show that the external cost – even when roads are not hypercongested...

We estimate the marginal external congestion cost of motor-vehicle travel for Rome, Italy, using a methodology that accounts for hypercongestion (a situation where congestion decreases a road's throughput). We show that the external cost - even when roads are not hypercongested - is substantial,...

Parking policies have significant environmental and economic implications, which have often been left unconsidered. This paper reviews the relevant literature to provide a deeper understanding of the main environmental and economic consequences of common parking policies, and suggest policy...

This paper explores the interactions between congestion pricing and a tax-distorted labor market within a monocentric urban equilibrium model. We compute the efficiency gains of various second-best policies, i.e. combinations of toll schemes and revenue recycling programs, with a predetermined...

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...

We analyze the effects of commodity taxation in markets where suppliers implement second-degree price discrimination schemes, such as offering different package sizes and quality-differentiated versions of the same product. In these markets, suppliers distort the quantity (or quality) intended...
