    The effect of transport policies on car use: A bundling model with applications
    (2013) Gallego, Francisco; Montero, Juan-Pablo; Salas, Christian
    Borrowing from the bundling literature, the paper presents a novel model of vertical and horizontal differentiation applied to transport decisions: households differ in their preferences for transportation modes - cars vs public transport - and in the amount of travel. Using few observables, the model is then used to interpret and compute policy costs associated to the effects of two major transport policies: the driving restriction program introduced in Mexico-City in November of 1989 and the public transport reform carried out in Santiago-Chile in February of 2007. Both policies had the unintended impact of increasing the number of cars on the road; and their associated transport costs are estimated, respectively, to be about 5% and 9% of the value of the vehicle stock at the time of implementation.

    The effect of transport policies on car use: Evidence from Latin American cities
    (2013) Gallego, Francisco; Montero, Juan-Pablo; Salas, Christian
    In an effort to reduce air pollution and congestion, Latin American cities have experimented with different policies to persuade drivers to give up their cars in favor of public transport. This paper looks at two of such policies: the driving restriction program introduced in Mexico City in November of 1989-Hoy-No-Circula (HNC)-and the public transport reform carried out in Santiago in February of 2007-Transantiago (TS). Based on hourly concentration records of carbon monoxide, which comes primarily from vehicles exhaust, we find that household responses to both HNC and TS have been not only ultimately unfortunate-more cars on the road and higher pollution levels-but also remarkably similar in two important aspects: on how policy responses vary widely among income groups and on how fast households adjust their stock of vehicles, when they do.
