Abstract
This paper aims to discuss two issues that have inflicted some inefficiency in Latin American urban public transport regulation: firstly, the lack of co-ordination between the authorities competent for different governmental resorts that are relevant for transportation administration (i.e. administration of infrastructure, traffic and urban development); secondly, the lack of any competitive stress that could lead the incumbent firms the struggle for more productive efficiency. These two aspects are analysed in two case studies, namely those of Recife Metropolitan Area (in North-eastern of Brazil), and of San José (Capital City of Costa Rica).
