Heterogeneity of Socail Classes and Job Accessibility: Implications of Transports Policies in Bogota

Transport in Bogotá (Colombia) has been the subject of several papers, but no one has treated the impact of the transport network on the disposition of employment in the city. Improvement of a public transport system such as the Transmilenio is supposed to be beneficial to everyone in the city. However, it might be that only a portion of the inhabitants benefit from this improvement. The aim of this paper is to demonstrate that improvements in public transport are not necessarily synonymous with benefits to every social class, especially when talking about a city with a great deal of heterogeneity in its social composition. To shed light on the relation between transport accessibility and social classes within the different zones in Bogotá, the definition of the effective size of a labor market in a city will be necessary. We will support this with a study of the existing literature about the effective size of a labor market. The results will give us enough tools to know whether or not an enhancement of the public transport system will have a direct effect on the type of jobs or social classes there are in the different zones of Bogotá. Can enhancements of public transport determine the level of social inclusion within a city like Bogotá?
