    Cost-Effective Measures for Reducing Road Fatalities in the Short Term
    (TAYLOR & FRANCIS LTD, 2011) Ignacio Rizzi, Luis; Cumsille, Sebastian; Fresard, Francisco; Gazmuri, Pedro; Carlos Munoz, Juan
    When traffic safety statistics in less developed countries (even those where enormous progress has been made in the last years) are compared with those of more advanced countries, it is evident that there is still a great deal to be done. Using Chile as a case study, we propose a set of measures to significantly reduce fatalities in the short term. A simple methodology is proposed to guide the process of selecting the most promising measures, taking into account their cost-effectiveness. Eight such measures are identified and their potential benefits and costs of implementation are estimated for our case study. Special care is taken in choosing measures aimed at protecting vulnerable road users who represent around 50% of road fatalities in Chile. The plan we propose has the potential to reduce 460 fatalities per year (i.e. 21%), as a conservative estimate. A discussion on the transferability of these results to other developing nations is offered.

    Simple Model of Road Infrastructure Financing The Impact of Different Funding Schemes
    (2014) Ignacio Rizzi, Luis
    This paper explores the impact of three different funding schemes on road infrastructure provision: road tolls, fuel taxes, and consumption taxes. A simple model is developed that incorporates three relevant features: fuel costs dependent on congestion, fuel efficiency, and different types of agent. The model illustrates how congestion and distributional impacts vary depending on the funding scheme. The model also shows that if fuel efficiency were fixed, fuel taxes would be a perfect substitute for road tolls, even if fuel consumption depends on congestion.

    Valuing air quality impacts using stated choice analysis: Trading off visibility against morbidity effects
    (2014) Ignacio Rizzi, Luis; De La Maza, Cristobal; Abdon Cifuentes, Luis; Gomez, Jorge
    Direct valuation of air quality has as a drawback; that estimated willingness to pay figures cannot be apportioned to the several environmental goods affected by air quality, such as mortality and morbidity effects, visibility, outdoor recreation, among others. To address this issue, we implemented a survey in Santiago de Chile to identify component values of confounded environmental services by means of a choice experiment. We designed a survey where two environmental goods, a morbidity health endpoint and improved visibility, had to be jointly traded off against each other and against money in a unified framework.
