Abstract

Abstract: This paper presents a theoretical model in order to better understand the elaboration of Public-Private Partnership contracts. Starting from the model developed by Iossa and Martimort (2012), we consider an additional parameter that measures the sensibility of the effort made in between the stages of the project. We also delimitate the numerical range of the variable that determines the technology flexibility. In this regard, a bundling regime, under which the companies form a consortium, presents better results than when they are contracted separately. This is a consequence of the first model, in which the companies are able to internalize the externalities of the productive process. On the other hand, even though the bundling regime is more efficient, the government should seek mechanisms to monitor the quality of services.Resumo: Este trabalho desenvolve um modelo teórico para compreender a elaboração do desenho de Parcerias Público Privadas. Toma-se como base o modelo de Iossa e Martimort (2012), modificando-o com a adição de um parâmetro que mede a sensibilidade dos esforços entre os estágios do projeto e também delimitando a variável que determina a flexibilidade da tecnologia. Neste sentido, o regime de bundling, em que as empresas são agregadas em um consórcio, mostra-se se superior ao que as empresas são contratadas separadamente. Isto se dá porque no primeiro modelo, as firmas conseguem internalizar as externalidades advindas do processo produtivo. Por outro lado, mesmo que este regime se mostre mais eficiente, o governo deve procurar mecanismos que monitorem eficientemente o índice de qualidade dos serviços.
