Public-Private partnership frameworks for financing affordable housing: Lessons and models

The pressing need for affordable housing in both developed and developing countries has prompted governments to explore innovative financing mechanisms, with Public-Private Partnerships (PPPs) emerging as a viable solution. This paper examines the frameworks, lessons, and models of PPPs for financing affordable housing, aiming to provide insights into their effectiveness and scalability. PPPs combine the resources, expertise, and efficiencies of both the public and private sectors to address the housing affordability crisis. By leveraging the strengths of each sector, PPPs aim to reduce financial burdens on governments while ensuring the delivery of quality housing solutions. This review outlines the various PPP models, including build-operate-transfer (BOT), design-build-finance-operate (DBFO), and lease-develop-operate (LDO), highlighting their structural differences and application contexts. Key components of successful PPP frameworks include clear regulatory environments, transparent procurement processes, risk-sharing mechanisms, and robust stakeholder engagement. Regulatory frameworks that support PPPs play a critical role in providing legal certainty and fostering investor confidence. Transparent procurement processes ensure fairness and competitiveness, while effective risk-sharing mechanisms distribute financial, construction, and operational risks appropriately between public and private partners. Engaging stakeholders, including communities and civil society, is essential for aligning project objectives with local needs and ensuring social acceptance. Case studies from various regions illustrate the practical application and outcomes of PPP frameworks. In the United Kingdom, the Affordable Homes Programme (AHP) has effectively utilized PPPs to deliver thousands of affordable housing units, demonstrating the benefits of strong regulatory support and private sector participation. Singapore's Housing and Development Board (HDB) employs PPP models to maintain high housing standards while ensuring affordability through extensive government subsidies and private sector involvement. In South Africa, the Social Housing Regulatory Authority (SHRA) leverages PPPs to develop rental housing for low- and moderate-income households, highlighting the importance of government incentives and capacity-building initiatives. The review concludes that PPP frameworks, when effectively designed and implemented, can significantly enhance the availability of affordable housing. Lessons learned from successful models emphasize the need for supportive policies, transparent processes, and inclusive stakeholder engagement. Policymakers and practitioners can draw on these insights to develop tailored PPP approaches that address specific housing challenges and contribute to sustainable urban development.

Reforming Public-Private Partnerships in Railway Services: Learning from the Jakarta Monorail Project Debacle

Public-Private Partnerships (PPPs) offer a promising strategy for accelerating railway infrastructure development, yet they entail significant risks if not executed correctly. Indonesia has adopted PPPs since the 1990s, but their impact on railway services remains underexplored. This paper suggests improvements to Indonesia’s railway PPP mechanism to improve effectiveness, efficiency, and service deliverability. It argues that the effectiveness of railway PPPs is hindered by the public sector’s limited capacity and weak regulatory and institutional frameworks. The research employs a case study of the Jakarta Monorail project, terminated in 2015 after 11 years of problematic development. The research methods include literature reviews and a comparative analysis of the case with two prominent railway PPPs in other developing countries: the Bangkok Transit System in Thailand and the Delhi Mass Rapid Transit System Phase I in India. The findings lead to two key recommendations for the government: reorganizing the roles and coordination processes of key PPP agencies and establishing a continuous capacity-building scheme for PPP stakeholders. These recommendations may create a more supportive environment for PPPs, thereby increasing the likelihood of successful railway PPP implementation in Indonesia.

Public-private partnerships in health sector innovation: Lessons from around the world

Public-Private Partnerships (PPPs) have emerged as a crucial mechanism for fostering innovation in the health sector globally. This review encapsulates the lessons learned from diverse PPP models worldwide, highlighting their significance and impact. PPPs in healthcare innovation entail collaboration between governmental bodies, private enterprises, and sometimes non-profit organizations to address challenges, such as limited resources, expertise, and infrastructure, while leveraging the strengths of each sector. The success of PPPs relies on effective governance structures, clear objectives, and mutual accountability. One notable example is the United Kingdom's NHS Innovation Accelerator, which partners with industry leaders to fast-track the adoption of innovative healthcare technologies within the National Health Service (NHS). Through this initiative, pioneering solutions, ranging from digital health platforms to medical devices, have been implemented, enhancing patient care and operational efficiency. Similarly, in low-resource settings like sub-Saharan Africa, PPPs have played a pivotal role in improving access to essential healthcare services. Projects such as the Medicines for Malaria Venture (MMV) collaborate with pharmaceutical companies, governments, and research institutions to develop affordable antimalarial drugs tailored to the region's needs. In the realm of medical research and development, partnerships like the Coalition for Epidemic Preparedness Innovations (CEPI) have demonstrated the power of international collaboration in addressing global health threats. CEPI brings together governments, philanthropic organizations, and the private sector to expedite the development of vaccines against emerging infectious diseases, as witnessed during the COVID-19 pandemic. However, challenges persist in PPP implementation, including complex regulatory frameworks, funding uncertainties, and divergent interests among stakeholders. Lessons from successful PPPs underscore the importance of transparent communication, stakeholder engagement, and sustained political commitment. In conclusion, PPPs in the health sector represent a dynamic avenue for catalyzing innovation and driving transformative change. By drawing insights from diverse experiences worldwide, policymakers and practitioners can refine existing frameworks and foster sustainable partnerships to tackle evolving health challenges effectively.

The Power(lessness) of Flexibility in Public–Private Partnerships: Two Capital Projects From the National Capital Region

This article draws on the new stakeholder theory to examine the role of flexibility in the decision process within capital-intensive public–private partnerships (PPPs). It highlights that successful PPPs rely on the project sponsor’s ability to effectively utilize market stakeholders’ critical resources (i.e., information and expertise) to maximize economic value creation, and to gain nonmarket stakeholders’ critical resources (i.e., support) through equitable social value identification and distribution. Drawing on two case studies in the national capital region of the United States, this article proposes a theoretical view to understand flexibility and stakeholder management for capital-intensive PPPs.

Therapeutic developments for tuberculosis and nontuberculous mycobacterial lung disease.

Tuberculosis (TB) drug discovery and development has undergone nothing short of a revolution over the past 20 years. Successful public-private partnerships and sustained funding have delivered a much-improved understanding of mycobacterial disease biology and pharmacology and a healthy pipeline that can tolerate inevitable attrition. Preclinical and clinical development has evolved from decade-old concepts to adaptive designs that permit rapid evaluation of regimens that might greatly shorten treatment duration over the next decade. But the past 20 years also saw the rise of a fatal and difficult-to-cure lung disease caused by nontuberculous mycobacteria (NTM), for which the drug development pipeline is nearly empty. Here, we discuss the similarities and differences between TB and NTM lung diseases, compare the preclinical and clinical advances, and identify major knowledge gaps and areas of cross-fertilization. We argue that applying paradigms and networks that have proved successful for TB, from basic research to clinical trials, will help to populate the pipeline and accelerate curative regimen development for NTM disease.

Collaboration in a Partnership for Primary Health Care: A Case Study From Papua New Guinea.

In low- and middle-income countries, public-private partnerships (PPPs) are often used to support the delivery of primary health care (PHC). We explore the processes of collaboration in a corporate social responsibility investment in PHC that was delivered through a PPP model in Western Province, Papua New Guinea, in 2009-2018 to strengthen PHC services. Qualitative interviews were conducted with stakeholders in the PPP (N=20). Key program documents were also reviewed. Data were coded using a general inductive approach, and Actor-Network Theory (ANT) was used to frame the analysis. Four dominant themes emerged: (1) interpersonal relationships accelerate collaboration, (2) collaboration requires time, (3) formal governance structures encourage collaboration, and (4) internal change disrupts collaboration. The research provides insight into the role of collaboration for more efficient, effective, and impactful design and implementation of PPP for PHC. It makes suggestions for how ANT may be used when designing PPPs and for the ongoing management of relationships between partners. We found ANT to be a useful framework to conceptualize the complex dynamics between the "actors" within the PPP and to identify opportunities for improvement where structural changes may be made to circumvent issues that may compromise effective collaboration. Collaboration is key to the success of PPPs for PHC. We found collaboration is not formulaic but is driven by actors, relationships, time, and governance. ANT can assist in designing, understanding, and managing the complex relationships between stakeholders of a PPP, who often come with diverse agendas, experiences, values, and perspectives.

The Success of Public Private Partnerships with Transparency and Accountability Principles

Harsh debates on the restructuring of public administration and the failures of states have continued for decades, Public Private Partnership (PPP) suggests a different function to the state as an application of the "New Public Management" approach, for solving some of these debates. Although PPP can be briefly defined as the provision of public services by the private sector, its complex relationship structure and risks behind this definition do likely make the model unsuccessful. In pursuit of the best model, international organizations and mechanisms, including the OECD, the UN, and the European Commission, have attempted to apply some models of successful examples, procedures, and laws. Some studies learning from faulty designs and experiences have focused on what should not be. As a result, the critical success factors seem to be the most proper tool to improve the PPP method. This study focuses on providing support information for countries trying to design and develop a PPP model. Afterward, it deals with the performance-measured PPP applications in the world in the context of transparency and accountability and reveals the significance of the principles of transparency and accountability in the success of the PPP model.

Public-Private Partnership in Healthcare is a Necessity in Difficult Times: A case study

Healthcare delivery is a risky enterprise for both public and private systems which may face adversity in a volatile, uncertain, complex, and ambiguous world. There has been a global emergence of Public-Private Partnership (PPP) hospitals to enhance delivery of sustainable healthcare, although its existence in developing countries remains limited. Risk management strongly influences PPP success; few PPP hospitals were able to meet contractually specified quality and performance requirements, creating debate regarding merits of the PPP model. Conversely, we present a case study of the first PPP hospital operated by not-for-profit organisation in New South Wales, Australia, to successfully complete the contract period. A Continuous Quality and Performance Improvement Framework was applied at five stages of organisational growth during the contract term. This case study demonstrates adaptive leadership and just organisational culture are equally important in providing high quality healthcare services to the community. We show the future potential of PPP model for service delivery as a third option to pure public or private sector hospitals, even in the post COVID-19 era when there is likelihood of financial instability in many settings.

Management tools for the public-private partnership model of construction enterprises

The article explores the mechanisms and challenges of applying public-private partnership (PPP) in strategic management of construction enterprises in Ukraine. It analyzes the impact of globalization and liberalization on the effectiveness of construction firms and seeks ways to optimize PPPs to ensure their adaptation to the changing market conditions. The article emphasizes the need to harmonize PPP practices with contemporary demands of sustainable development and to define a set of criteria that take into account economic, technical, organizational, and social aspects. Five main groups of criteria are proposed, aimed at improving PPP models and assessed through a wide range of indicators, including in line with the policy of the European Union. Expert interviews have been used to determine the relevance of the criteria, allowing for an objective assessment of the importance of each one. The essence of PPP as a tool for strategic management, providing a coordinated interaction between the state and private investors in the construction sector, is provided. The current state and prospects for the development of PPPs in Ukraine are analyzed, taking into account international experience and the specifics of the national market. The defined criteria and sub-criteria for innovative development should form the basis for creating an effective management model that considers all aspects of sustainable development and facilitates the implementation of strategic initiatives. The research results highlight the importance of technical-technological and organizational development as key elements of a successful PPP model. The proposed approaches and recommendations may serve as a foundation for improving the management of construction enterprises, including through the introduction of innovative technologies and management methods

Role of Public-Private Partnerships in Strengthening Pakistan's Healthcare System

Pakistan's healthcare system stands at a critical juncture, facing challenges that demand innovative solutions. Among these, the role of public-private partnerships (PPPs) emerges as a promising avenue to bridge gaps, enhance service delivery, and transform the healthcare landscape. The collaboration between public and private sectors has the potential to bring together diverse expertise, resources, and perspectives, ultimately leading to a more resilient and effective healthcare system.
 In a country where public healthcare resources often struggle to meet the demands of a growing population, PPPs offer a strategic approach. Private sector entities, with their operational efficiency and investment capabilities, can inject vitality into the system. The provision of healthcare services, infrastructure development, and technology implementation are areas where PPPs can make a substantial impact. This synergy allows the public sector to leverage the strengths of the private sector while ensuring equitable access to quality healthcare services for all citizens.
 However, successful PPPs in healthcare necessitate careful planning, transparent frameworks, and clear delineation of roles and responsibilities. Balancing financial viability with social responsibility remains a challenge. It is essential to strike a harmonious equilibrium where the interests of both sectors converge for the greater good. Moreover, effective governance and regulatory oversight are crucial to prevent any compromise on healthcare quality or ethics.
 As Pakistan strives to achieve its healthcare development goals, lessons from successful PPP models globally can offer valuable insights. These models emphasize collaboration built on trust, open communication, and a shared vision. By fostering an environment that encourages innovation and collaboration, Pakistan can harness the full potential of PPPs to create a healthcare system that is robust, inclusive, and responsive to the needs of its citizens.
 In conclusion, the role of public-private partnerships in strengthening Pakistan's healthcare system is undeniable. By pooling resources, knowledge, and expertise, both sectors can collectively address the challenges that have long impeded the nation's healthcare progress. A well-structured and ethically sound approach to PPPs can pave the way for a future where quality healthcare services are accessible to all, setting Pakistan on a transformative path toward healthier communities and improved well-being.

Exploring Risk Factors Affecting Sustainable Outcomes of Global Public–Private Partnership (PPP) Projects: A Stakeholder Perspective

As a model for delivering infrastructure initiatives, public–private partnerships (PPPs) have gained significant popularity in recent years. The globalization of PPP has exposed them to elevated risks emanating from the international real economy and financial market, which can ultimately result in project cancellations or distress. This study analyzes risk factors affecting the sustainable outcomes of global PPP projects from a stakeholder perspective. After identifying the interests of key stakeholders and examining how various risks influence stakeholders’ interests, a two-step binomial probit model is used to investigate domestic and international risk factors in PPP arrangements based on the World Bank PPI database. The empirical results indicate that inflation has a substantially positive effect on project failure, while factors such as PPP experience, central government involvement, exchange rate fluctuations, etc., significantly contribute to PPP success. In addition, the study demonstrates that trade openness and net foreign direct investment (FDI) inflow are crucial for the transmission of global risks. The study also provides policy implications and recommendations from a risk allocation–stakeholder relationship perspective to enhance the resilience of PPP initiatives based on these findings.

Repair as a circular strategy for increasing resource availability and health system resilience during a crisis

BackgroundHealthcare is a complex socio-technical system where nations regularly struggle with the misalignment between public needs and available resources. The advent of COVID-19 further exacerbated shortcomings, as evidenced by the global panic to find ventilators and beyond. However, the pandemic catalysed a successful Brazilian public-private voluntary partnership that united key industry players, industrial training centres and several volunteers, who, in the absence of a supportive government, could repair ventilators in record time, giving the health system means to succeed. ObjectivesCharacterise how a voluntary public-private partnership came into existence and codify recommendations on how it effectively used repair as a circular strategy to increase ventilator availability and bolster health system resilience. MethodsCase study using multiple data sources collected over 10 months, including national data, semi-structured interviews, daily reports, and internal communications. Sampling, research instruments, and subsequent qualitative data analysis and theory development grounded in repair strategy, resilience, and supply chain literature. ResultsA successful public-private voluntary partnership delivered 2,514 repaired ventilators, approximately 3% of the total ventilators in use in Brazil and impacting around 24,700 lives. Furthermore, effectively functioned as a first-responder bringing to hospitals approximately 500 repaired units as early as April 2020, surpassing the government's procurement and doing so just-in-time for Brazil's COVID 1st wave. More than 70 institutions and 700 professionals helped hospitals in 25 out of 27 Brazilian states. This case documents how the initiative persevered through adversity, including inadequate policies representing a widespread difficulty in enforcing the “right to repair”. Public interest summaryIn Brazil, automakers, the National Industrial Training Service and other organisations formed a voluntary and temporary alliance to repair broken ventilators that had accumulated in hospitals. This initiative took place at the beginning of the COVID-19 pandemic and returned 2,514 ventilators to hospitals, supporting patient care and partially alleviating the shortage of ventilators. This repair depended on the training of technical staff who had never worked with health equipment before. In addition to training, there was a need to share information and manuals, calibrate repaired equipment, procure spare parts, organise logistics and find funding, amongst other activities, meaning that it was a wide scale operation involving several organisations - both within and outside the health system. This research demonstrates the role of ventilator repair in making a health system more resilient in the event of a health emergency, and the urgent need to develop strategies to make repair an everyday commitment.

Public-private partnerships and achievement of public value: The experience of Jordan’s Queen Alia International Airport

Despite the existence of a voluminous body of literature covering the impact of infrastructure public-private partnerships (PPPs) on public value within the context of Western countries, scant attention has been paid to this topic in the Middle East. Given that the region has hosted numerous PPP projects that were implemented even without the rudimentary legal and regulatory frameworks considered essential for such projects to succeed, a study of PPPs within that region would thus be particularly useful, since an unpacking of the success factors for PPPs in the Middle East can reveal important practical insights that will advance the knowledge of PPP success factors overall. This paper, therefore, explores the rehabilitation and expansion of Jordan’s Queen Alia International Airport via the PPP route. It finds that the factors contributing to the project’s successful implementation can be categorized into those on the macro level related to political support, and the micro level factors concerned with management of daily activities involved in the partnership between the public and private sectors.

Public–Private Partnerships: A Fresh Risk-Based Approach to Water Sector Projects

This study focused on the unbalanced relationships that can arise in current public–private partnership (PPP) risk management frameworks, especially in developing countries’ water sectors. Different stakeholders’ perceptions of risk management were examined by analyzing 15 interviews in Portugal and Mozambique. The hybrid method included semantic, descriptive statistic, content, and narrative analyses. To achieve the research objectives, the semi-structured interview transcripts were processed using quantitative and qualitative techniques to collate relevant actors’ opinions of risk management in PPP water projects. Five risk categories were identified. The interviewed experts ranked the financial risk category as the most crucial, followed by infrastructure, commercial, technical and operational, and context risks. However, when the transcripts were evaluated from a risk factor perspective, the context risk category unexpectedly jumped to first place. Twenty-five high-impact risk factors were isolated in the semi-structured interview contents. The top five most critical risk factors were political interference, no performance measurement baselines, an unfavorable private investment climate, nonpayment of bills, and water assets uncertain condition. The results comprise a fresh contribution to the existing knowledge about experts’ perceptions of PPP contract risks, including that prior research and specialists categorize financial risks as the most important. The findings further reveal that experts consider managing context risks to be the key factor in PPPs success in developing countries, as well as highlighting the need to explore these risks more fully in emerging economies’ water sectors. In addition, a complete risk management cycle is proposed based on the interviewed professionals’ opinions, in which risk assessment and risk treatment or mitigation measures are dealt with simultaneously.

A selectivity index for public-private partnership projects in the urban water and sanitation sector in Latin America and the caribbean

The rapid urban development, the Agenda 2030, the climate change adaptation and the COVID 19 crisis highlight the need to increase investment in public infrastructure and improve water supply and sanitation services. For this, an alternative to traditional public procurement is the participation of the private sector under the public-private partnership (PPP) model. The objective of this article is to develop a tool based on critical success factors (CSFs) that allows for evaluation during early stages of the convenience of developing a PPP project for W&S in urban areas of Latin America and the Caribbean. The index was developed based on literature review (779 variables), review of cases (20 variables) and expert opinion to assign them an estimated value of importance. The results were analysed by exploratory and confirmatory factor analysis, selecting 17 main variables grouped into 6 CSFs, the most relevant of which are Convenience, Certainty, Leadership, Attraction, Performance and Reliability. The application of this index allows an early assessment of the feasibility of a PPP project and/or the selection of the alternatives with the best chances of success. On the other hand, this study contributes to the international discussion on the most relevant elements related to the success of PPP in W&S projects.
