It has been argued that urban planning policies, through minimum parking requirements, and income tax policies induce free employer parking. We show that tax policies induce welfare losses in the order of 12% of parking resource costs, implying an annual deadweight loss in the order of € 5...

This paper assesses the impact of the September 11th terrorist attacks and its after-effects on U.S. airline demand. Using monthly time-series data from 1986-2003, we find that September 11th resulted in both a negative transitory shock of over 30% and an ongoing negative demand shock amounting...

This study estimates the dose-response relationship between Body Mass Index (BMI) and crash risk in commercial motor vehicle operators. Intake data was collected on 744 new truck drivers who were training for their commercial driver's licenses at a school operated by the cooperating trucking...

Due to Federal regulations, automobile air bag availability was a model-specific discontinuous function of model year for used vehicles in the 1990s and early 2000s. We use these discontinuities and the gradual increase in the supply of air bags to trace out the demand curve for air bags and the...

This study adopts a discrete choice modelling methodology to evaluate individuals' preferences over planning alternatives for an urban site of environmental interest. Since such projects involve some uncertainty and irreversibility, a special attention is devoted to the estimation of the...

In this paper, we propose a new spatial framework to model excess commuting of workers and we show empirical differences between the self-employed and employees in the US. In a theoretical framework where self-employed workers minimize their commuting time, employees do not minimize their...

Due to Federal regulations, automobile air bag availability was a model-specific discontinuous function of model year for used vehicles in the 1990s and early 2000s. We use these discontinuities and the gradual increase in the supply of air bags to trace out the demand curve for air bags and the...

In this article, we investigate the use of hedonic pricing method to measure freight value of time. We concentrate on the demand side of the freight market (that is shippers) and give a pre-cise definition to transport duration. We analyse the different temporal dimensions of freight...

This paper assesses the effectiveness of child safety seat laws. These laws progressively increased the mandatory age up to which children must be restrained in safety seats in cars. We use US Fatality Analysis Reporting System (FARS) data from 1978 to 2011 and rich state-time level variation in...
