This paper identifies the causal impact of urban rail transport on firm location. The evaluation of transport infrastructures always faces an important issue of endogeneity since rail lines are not located randomly. We use the natural experiment offered by the Regional Express Rail progressively...

We present a directed variant of Salop’s (1979) model to analyze bus transport dynamics. Players are operators competing in both cooperative and non-cooperative games. Utility, like in most bus concession schemes in emerging countries, is proportional to the total fare collection. Competition...
