Abstract: Public transport is central to commuting in many cities around the world. This paper studies the role of public transport in shaping the urban structure. Using the classic monocentric city framework, we model public transport as a mode that can only be accessed through walking to a limited set of stops. We show that all gradients in the city follow a non-monotonic pattern with peaks at the stations. In particular, prices and densities are higher near the stations where dwellings are smaller. We also show that public transport can explain the existence of suburbs that are disconnected from the city (leapfrog development) and that the stylized framework is able to reproduce many of the regularities observed in cities in which commuting by public transport is important. We then study the effects of implementing pricing schemes in which fares change with distance. We show that even when there are cost gains from reducinhg the distance traveled and in the absence of externalities, an inverse fare-distance relationship may yield higher welfare than a flat fare and than a fare that increases with distance. Finally, we study the impact of different pricing schemes on the spatial sorting of households of different incomes.
