Dt denotes seasonal dummies for month of the year, day of the ds, hour of the day, and interactions between weekends and hour of the day. The author has also benefited from discussions with Eduardo Behrentz and Jorge E. For instance, around 1. The purpose of the chapter is to illustrate the need for temporally differentiated road pricing using Stockholm as a case study.

Although CO concentrations at this station are very low, increased 33444 levels were remarkably observable. If so, what are they and what quantity? This is the moment to thank all of you for your collaboration and help. If conpew is available, any previous year can be included too. Continuing with the theme of Mobile Sources, conpws second chapter analyzes how the congestion charge already implemented in Stockholm, Sweden could be used as an instrument to reduce vehicular traffic and satisfy air quality standards AQSaccounting for temporal variations conprs the restricted dispersion of certain pollutants.

Moreover, private vehicles cause a deterioration of the air quality through the emission oftons of CO, 18, tons of nitrogen oxides NOxand 46, tons of hydrocarbons per year SDA and Uniandes, I would like to start by expressing my infinite thanks to Jesus, the name that is above every name. All remaining errors are the responsibility of the author. As an environmental economist, I enjoy engaging in interdisciplinary discussions and research.
C45, C53, Q53 Keywords: Because the program was implemented in phases, it was possible not only to study the impact of the program, but also to distinguish between the short- and long-run effects for each phase of restriction. Concentration levels or the rate at which cconpes pollutants are accumulated in the atmosphere may be a result of multiple factors such as road dust or chemical and photochemical reactions among pollutants.
She has taught me that knowledge is to be shared and is a privilege that should make a person more humble.

Such responses based on experience might limit the effectiveness of the drastic phase of a phased-in program. The fourth chapter is about the interaction of the refunded nitrogen oxides charge and emission standards and their effect on the timing and decision to invest in abatement technologies. Overall, the results show an increase in vehicle 344 and total driving, suggesting that households were more responsive to drastic than moderate restrictions, i.
The first chapter evaluates the effectiveness of the driving restriction program Pico y Placa implemented in Bogota, Colombia to reduce congestion and air pollution. International Conpess of Madrid.

Assessments of the effects of driving restrictions on traffic congestion and air pollution in practice have yielded conflicting conclusions regarding their effectiveness. If data and updates are available, please provide this data and note the year. One factor that complicates the analysis of CO concentrations is meteorology.

There is also evidence that PYP has increased the stock of private vehicles — an outcome that is consistent with no decrease in gasoline consumption. These may include permit schemes, taxes, fees, subsidies and emission standards. Gasoline taxes, on the other hand, have tended to reduce gasoline usage in Bogota, suggesting that a price-based mechanism would be more effective in reducing driving.

General reports about pollution trends and meteorological information in different places of the city are publicly available by the RMCAB through its website http: Accelerated retirement program 7. I highly appreciate your suggestion for the title of this thesis and your encouragement and support to attend the Bergen Economics of Energy and Environment Research Conference.
Under temperature inversion episodes, motor vehicle emissions are trapped near the ground level, thus potentially introducing a bias in the estimations of CO concentrations as a proxy for car use during those hours. This is accomplished using both Monte Carlo simulation and an extensive application to air quality in Bogota, one of the largest and most polluted cities in Latin America.
The net NOx charge only plays a role in xiii stimulating adoption of the most expensive technologies: The policy was implemented as a strategy to control the oversupply of public transport vehicles at a low level of occupancy, 6 Inthe restriction period was extended by 30 minutes in the morning Using data on carbon monoxide COgasoline consumption, and vehicle sales and registration, this study shows that CO concentrations and vehicle use did not decrease in the long run, despite an initial improvement in air quality for some periods of the day in both phases of the program.
The study indicates that the achievement of AQSs in Stockholm would require the charge to be increased for all seasons and most hours of the day.
However, such data is usually scarce. Epidemiological studies have found that the risk of mortality increases under severe exposure to high concentrations see Lippmann, ; Brunekreef and Holgate, In particular, in andthe monitoring network experienced maintenance problems, yielding the lowest number of valid observations in the entire history of the network, making it impossible to construct reliable continuous series for several pollutants.
Thus, temperature inversion is an indicator variable that takes the value of one under those episodes, and zero otherwise.
