Why Public–Private Partnerships Fail

A Structural Diagnosis of Capital Misalignment

What is an Architectural Diagnosis?

Unlike deep dives that examine successful regenerative organisations, diagnoses analyse sectors where architectural constraints shape participant behaviour. PPPs do not fail because they are badly implemented—they fail because they are architecturally incapable of delivering regenerative public goods.

Public–private partnerships remain a dominant instrument for financing public infrastructure despite decades of evidence documenting cost overruns, renegotiations, service degradation, and public backlash. Existing critiques treat failure as contingent on contract quality, governance capacity, or political context.

This diagnosis advances a different claim: PPPs fail structurally, not accidentally. They embed financial extraction, contractual rigidity, and refinancing risk into systems whose missions require long-horizon capital continuity and capability renewal. PPPs fail to decouple capital from political, financial, capability, and civic fragility cycles—and instead optimise cashflow timing and return extraction rather than mission-aligned performance.

“The failure of public–private partnerships is not empirical, ideological, or managerial. It is architectural.”

Core thesis of this diagnosis

The Structural Failure

PPPs are designed around a fundamental incapacity: they attempt to bind long-horizon public goods to short-horizon private incentives through rigid contracts. This is not a design flaw that can be fixed—it is the design itself.

Failure 1

Embedded Fragility

PPPs do not remove political fragility; they reconfigure it. Long-term contracts are frequently renegotiated following elections, fiscal crises, or policy shifts. Renegotiation is not an exception but a structural feature—reflecting the impossibility of specifying performance over decades.

Failure 2

Temporal Misalignment

Mission cycles are determined by asset lifetimes (50-100 years), capability renewal, and intergenerational service. PPPs are governed by concession periods (25-30 years), debt amortisation, and equity exit windows. These temporal structures are fundamentally incompatible.

Failure 3

Embedded Extraction

Private capital enters PPPs expecting risk-adjusted returns through availability payments, user charges, or refinancing gains. This diverts resources from capability renewal and imposes a temporal discipline oriented toward return realisation rather than regeneration.

Result

Structural Incapacity

The combined effect is not poor average performance but structural incapacity. PPPs cannot be reformed into regenerative systems through better contracts, improved governance, or enhanced public-sector capability. Such reforms address symptoms without altering the underlying capital architecture.

What We've Lost: Historic Benefaction

To demonstrate that alternative outcomes are possible, consider historic public benefaction as a control case. Libraries, universities, museums, and hospitals created through benefaction often outlived their founders by generations. Their endurance cannot be explained by donor virtue alone—it must be explained structurally.

Architectural Features of Durable Benefaction

Where historic benefaction succeeded in creating durable public goods, it shared architectural features that differ fundamentally from PPPs:

Capital Removed from Annual Budgeting

Endowments, trusts, and land grants established capital bases that did not reset each fiscal year. Asset maintenance was not subject to routine budgetary competition.

Governance Separated from Political Turnover

Boards of trustees, charters, and foundation statutes created institutional memory that persisted beyond changes in government. Decisions were made within frameworks designed to endure.

No Embedded Extraction

Capital was given or endowed rather than invested for financial return. No equity exits, refinancing gains, or performance-linked payouts. Resources remained within the institution.

Continuity Materially Embodied

Physical assets—buildings, campuses, collections—encoded long time horizons. Decay could not be hidden through accounting adjustments. Architecture itself reinforced intergenerational responsibility.

What the Control Case Reveals

Durable public goods have been delivered when capital was architected to support long-horizon missions and insulated from short-term extraction and political volatility. PPPs represent not an evolution of this architecture, but a reversal: they reintroduce fragility through contracts, refinancing, and return extraction.

The lesson is not that generosity should replace public finance, but that capital architecture matters more than contractual sophistication. When capital behaves in accordance with mission time, institutions can endure. When capital is governed by financial and political cycles, no amount of contractual detail can compensate.

Why PPPs Persist Despite Failure

If PPPs are structurally incapable of delivering regenerative public goods, their continued use demands explanation. Their persistence reflects the fact that PPPs solve a different problem from the one they are ostensibly designed to address.

Fiscal Illusion

PPPs move liabilities off government balance sheets while creating equivalent long-term payment obligations. They allow projects without breaching fiscal rules or triggering credit-rating concerns.

Political Timing

PPPs deliver visible infrastructure during current terms while deferring costs to future administrations. They are instruments of budgetary smoothing and political timing, not long-horizon solutions.

Institutional Legibility

Treasury departments and development banks possess established frameworks for PPPs. Legal, financial, and consulting professions have specialised expertise. This creates path dependence regardless of mission fit.

Risk Displacement

PPPs allow governments to claim risk transfer even when risk merely shifts into less visible forms. When projects fail, responsibility is diffused across contractual interfaces—politically advantageous despite higher long-term costs.

PPP persistence does not require belief in their superiority. It requires only the absence of a credible alternative capital architecture. As long as governments lack access to capital that decouples from political and financial fragility cycles, PPPs will remain attractive despite their failures.

RCA Framework Analysis

Applying IRSA’s Regenerative Capital Architecture framework reveals why PPPs are structurally incapable of regeneration.

Delta (Δ) — Decoupling

Absent

Regenerative systems decouple capital from fragility cycles. PPPs do the opposite: they tightly couple infrastructure to political, financial, and electoral cycles.

Contract terms set by political cycle

Financing around fund lifecycles (7-10 years)

Renegotiation tied to external events

Lambda (Λ) — Alignment

Misaligned

Regenerative systems align capital with mission cycles. PPPs align capital with return extraction—governing behaviour toward cashflow timing, not capability renewal.

Incentives weaken toward contract end

Deferred maintenance is rational

Asset sweating maximises returns

What Would Work Instead

PPP reform is futile. Addressing public-good failure requires new capital architectures that satisfy the conditions historic benefaction achieved: decoupling from fragility cycles and alignment with mission cycles.

Non-Extractive Capital

Capital structures where returns depend on public value creation, not financial extraction. Resources remain within the system to compound capability rather than being withdrawn through dividends, interest, or exit.

Multi-Cycle Governance

Institutions designed to operate across political cycles, with governance structures that span infrastructure lifecycles. Accountability that persists across 50-100 year horizons through structural design, not contractual clauses.

Regenerative Capital Systems

Capital that can persist, recycle, and renew without periodic re-contracting or refinancing. Systems designed to strengthen institutions over time rather than extract from them— the architectural principles of Perpetual Social Capital applied to infrastructure.

Theoretical Contribution

“What has been lost is not generosity or competence, but attention to capital architecture.”

This diagnosis contributes to regenerative systems theory by demonstrating:

PPP failure is structural, not contingent. No amount of better contracts can fix a model whose temporal logic is incompatible with public goods.
Historic benefaction succeeded through architectural features—decoupling, non-extraction, embodied continuity—that PPPs systematically reverse.
PPP reform is a dead end. Addressing public-good failure requires rethinking capital architecture, not refining contracts.
