This article applies political economy theory to public-private partnerships (PPPs). First, we propose that social welfare is the appropriate normative evaluation criterion to evaluate the social value of PPPs. Second, we specify the goals of PPP participants, including private-sector partners and governments. Third, we review the observed outcomes of PPPs and analyze them from both a political economy perspective and a social welfare perspective. Fourth, based on a comparison of the actual outcomes of PPPs to normatively desirable social welfare outcomes, we propose some 'rules for governments' concerning the design of government PPP institutions and the management of PPPs. We argue that if governments were to adopt these rules there would be fewer PPPs in total, they would be more like traditional government contracts and there would be a greater likelihood of improved social welfare. However, political economy theory also explains why implementation of any reform will be difficult.
La economía política de las alianzas público-privadas. Análisis de su valor socialEste artículo aplica la teoría de la economía política a las alianzas público-privadas (PPPs). Los autores proponen, en primer lugar, el bienestar social como criterio apropiado para evaluar las PPPs. Precisan, a continuación, los objetivos de los participantes en las PPPs, tanto de los socios privados como de los gubernamentales. En tercer lugar, pasan revista a los resultados observados en las PPPs y los analizan simultáneamente desde perspectivas de economía política y de bienestar social. Porúltimo, se basan en una comparación de resultados efectivos de las PPPs con resultados normativamente deseables en términos de bienestar social, proponiendo a los gobiernos algunas "reglas" * We would like to thank Piet de Vries for helpful comments on an earlier version of this article.
