    Risk Allocation in Unsolicited and Solicited Road Public-Private Partnerships: Sustainability and Management Implications
    (2020) Castelblanco, Gabriel; Guevara, Jose; Mesa, Harrison; Flores, Diego
    Risk allocation plays a crucial role in the successful development of public-private partnership (PPP) projects. However, despite being an important topic for scholars and practitioners, the existing literature does not provide sufficient evidence on how managing risks in solicited (SP) and unsolicited (USP) road PPP projects, and subsequently, on what the sustainability implications are for such managerial processes. This study aims to extend risk allocation studies by analyzing contracts in Chilean highway PPPs over the last decade based on a systematic content analysis framework and case study data. The framework was developed through line-by-line coding of contract provisions associated with risk-related issues, and data were collected from semi-structured interviews with Chilean PPP practitioners. Results show that, although the majority of risks are either shared or transferred to the private party in most contracts, there are important variations in the way allocation procedures are implemented for SPs and USPs. Contracts analyzed revealed that risk arrangement mechanisms have usually focused on the economic dimension of sustainability without fully incorporating social and environmental considerations, increasing protests in the long-term. Conclusions indicate that risk allocation procedures and sustainability considerations are highly dependent on project-specific features and contextual factors. Overall, the analysis uncovers that the level of autonomy given to the private sector in both SPs and USPs has contributed to properly manage technical and economic risks, but has failed to successfully allocate social and environmental concerns.

    Semantic Network Analysis of Literature on Public-Private Partnerships
    (2021) Castelblanco, Gabriel; Guevara, Jose; Mesa, Harrison; Sanchez, Andres
    Public-private partnerships (PPPs) have motivated diverse bibliometric analyses of PPP research. Nevertheless, the evolution and connections between the main topics in the PPP domain have not been explored. To improve the understanding of the PPP research agenda, this study uses Content Analysis (CA) and Semantic Network Analysis (SNA) to expose relationships and trends in PPP research topics over the last two decades. These methodologies helped researchers to move beyond analyzing thematic trends in isolation in order to gain insight into the interrelationships among PPP topics by using qualitative and quantitative tools, which is difficult to achieve with other methodological approaches. The SNA metrics showed that the PPP research agenda evolved into a high-clustered network driven by five macrokeywords: financing and economic aspects, road infrastructure, public sector management, risk management, and contract management. These macrokeywords may enable the growth of the entire PPP research agenda, but they could also jeopardize the emergence of new research trends. Results show that the participation of some traditional PPP infrastructure types, such as power generation, rail, and tunnel, has been reduced, in contrast to more recent types such as healthcare and, especially, airport infrastructure. Similarly, research focus has shifted from examining traditional PPP issues in the US and European Union to analyzing PPP development in Africa, Latin America, and Asia. Overall, this study presents a more holistic understanding of the PPP body of knowledge, its evolution, and the interaction of its main topics.

    Social Legitimacy Challenges in Toll Road PPP Programs: Analysis of the Colombian and Chilean Cases
    (2022) Castelblanco, Gabriel; Guevara, Jose; Mesa, Harrison; Hartmann, Andreas
    Public-Private Partnership (PPP) programs have been developed widely for more than 30 years across the world. The continuity of these programs depends on an adequate balance of three-dimensional sustainability (i.e., economic, environmental, and social). Nevertheless, social sustainability has been demonstrated as being fragile because of the challenges to achieving the intended social legitimacy in PPP programs. This study aims to understand key challenges in achieving social legitimacy in road PPP programs by analyzing contractual clauses, legal frameworks, and stakeholders' interviews of two toll road PPP programs in Chile and Colombia. Three key challenges to social legitimacy were found: social involvement issues, distrust between impacted and responsible stakeholders, and lack of social criteria within toll tariff policy. Findings reveal that it is required to move beyond current consultation mechanisms and thoroughly involve the impacted groups as a relevant stakeholder typology in order to maximize value creation in user-pay PPP programs. In line with that, this study exposes that the claim of previous research for developing relational governance between the public and the private sectors is not enough for overcoming governance limitations and addressing social legitimacy in user-pay PPPs. It is also necessary to enhance relational governance in a triadic approach. This study contributes to the PPP body of knowledge by redirecting the discussion from overall legitimacy to social legitimacy challenges and by including the impacted stakeholders in the analysis of PPP governance mechanisms.
