This paper estimates the impact on Delhi’s air quality of a number of policy measures recently implemented in the city to curb air pollution using monthly time-series data from 1990 to 2005. The best known of these measures is the court-mandated conversion of all commercial passenger...

In this paper we evaluate and compare long-run economic effects of six road-pricing schemes aimed at internalizing social costs of transportation. In order to conduct this analysis, we employ a spatially disaggregated general equilibrium model of a regional economy that incorporates decisions of...

This paper reviews literature on the optimal design of pricing policies to reduce urban automobile congestion. The implications of a range of complicating factors are considered, such as traffic bottlenecks, constraints on which roads and freeway lanes in the road network can be priced, driver...

Economists have long advocated congestion pricing as an efficient way of allocating scarce roadway capacity. However, with a few exceptions, congestion tolls are rarely used in practice and strongly opposed by the public and elected officials. Although high implementation costs and privacy...

In determining the marginal cost of congestion, economists have traditionally relied upon directly measuring traffic congestion on network links, disregarding any “network effects,” since the latter are difficult to estimate. While for simple networks the comparison can be done within a...

Using individual travel diary data collected before and after the rail transit coverage expansion in urban Beijing, this paper estimates the impact of rail accessibility improvement on the usage of rail transit, automobiles, buses, walking, and bicycling, measured as percent distance traveled by...

In this paper we develop a framework for analyzing panel data with observations on rank ordered alternatives that allows for correlated random taste shifters across time and across alternatives. As a special case we obtain a nested logit model type for rank ordered alternatives. We have applied...

We study the interactions between fuel efficiency improvements in the transport sector and the oil market, where the efficiency improvements are policy-induced in certain regions of the world We are especially interested in feedback mechanisms of fuel efficiency such as the rebound effect,...

This paper studies the oil market effects of phasing out oil consumption subsidies in the transport sector. Welfare effects in different countries are also examined. We investigate potential feedback mechanisms of oil subsidy removal via lower oil prices in the global oil market, which may...
