Public–private partnership

Public–private partnership is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Public–private partnership rather than just read about it. In short: A public–private partnership (PPP, 3P, or P3) is a long-term arrangement between a government and private sector institutions. Typically, it involves private capital financing government projects and services up-front, and then drawing revenues from taxpayers and/or users for profit over the course of the PPP contract.

Key takeaways

  • Public–private partnership belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Public–private partnership to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Public–private partnership from memory before moving on to harder problems.

Reference excerpt

A public–private partnership (PPP, 3P, or P3) is a long-term arrangement between a government and private sector institutions. Typically, it involves private capital financing government projects and services up-front, and then drawing revenues from taxpayers and/or users for profit over the course of the PPP contract. Public–private partnerships have been implemented in multiple countries and are primarily used for infrastructure projects. Although they are not compulsory, PPPs have been employed for building, equipping, operating and maintaining schools, hospitals, transport systems, and water and sewerage systems. Cooperation between private actors, corporations and governments has existed since the inception of sovereign states, notably for the purpose of tax collection and colonization. Contemporary "public–private partnerships" came into being around the end of the 20th century. They were aimed at increasing the private sector's involvement in public administration. They were seen by governments around the world as a method of financing new or refurbished public sector assets outside their balance sheet. While PPP financing comes from the private sector, these projects are always paid for either through taxes or by users of the service, or a mix of both. PPPs are structurally more expensive than publicly financed projects because of the private sector's higher cost of borrowing, resulting in users or taxpayers footing the bill for disproportionately high interest costs. PPPs also have high transaction costs. PPPs are controversial as funding tools, largely over concerns that public return on investment is lower than returns for the private funder. PPPs are closely related to concepts such as privatization and the contracting out of government services. The secrecy surrounding their financial details complexifies the process of evaluating whether PPPs have been successful. PPP advocates highlight the sharing of risk and the development of innovation, while critics decry their higher costs and issues of accountability. Evidence of PPP performance in terms of value for money and efficiency, for example, is mixed and often unavailable.

Definition

There is no consensus about how to define a PPP. The term can cover hundreds of different types of long-term contracts with a wide range of risk allocations, funding arrangements, and transparency requirements. The advancement of PPPs, as a concept and a practice, is a product of the new public management of the late 20th century, the rise of neoliberalism, and globalization pressures. Despite there being no formal consensus regarding a definition, the term has been defined by major entities. For example, The OECD formally defines public–private partnerships as "long term contractual arrangements between the government and a private partner whereby the latter delivers and funds public services using a capital asset, sharing the associated risks". According to David L. Weimer and Aidan R. Vining, "A P3 typically involves a private entity financing, constructing, or managing a project in return for a promised stream of payments directly from government or indirectly from users over the projected life of the project or some other specified period of time". A 2013 study published in State and Local Government Review found that definitions of public-private partnerships vary widely between municipalities: "Many public and private officials tout public–private partnerships for any number of activities, when in truth the relationship is contractual, a franchise, or the load shedding of some previously public service to a private or nonprofit entity." A more general term for such agreements is "shared service delivery", in which public-sector entities join with private firms or non-profit organizations to provide services to citizens.

Debate on privatization

There is a semantic debate pertaining to whether public–private partnerships constitute privatization or not. Some argue that it isn't "privatization" because the government retains ownership of the facility and/or remains responsible for public service delivery. Others argue that they exist on a continuum of privatization, P3s being a more limited form of privatization than the outright sale of public assets, but more extensive than simply contracting out government services. Because "privatization" has a negative connotation in some circles, supporters of P3s generally take the position that P3s do not constitute privatization, while P3 opponents argue that they do. The Canadian Union of Public Employees describes P3s as "privatization by stealth".

Worked examples

Example 1 — a first encounter with Public–private partnership

Start with the simplest possible case. Write down what Public–private partnership claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Public–private partnership before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Public–private partnership ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Public–private partnership

In research
Public–private partnership appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Public–private partnership in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Public–private partnership is common in secondary-school and first-year university syllabi. It links to neighbouring topics Construction management, Government finances, Government procurement, so understanding it makes those chapters shorter.
In everyday life
Look for Public–private partnership outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
