Public Finance and Sovereign Debt
The Global Risks Alliance (GRA)
Public investment builds roads, power, water, schools and hospitals, but money spent does not always become assets that work. Efficiency gaps arise from weak appraisal, project selection, procurement, implementation and maintenance. This page sets out how public investment efficiency is lost and measured, which institutions shape it, and who decides.

Public investment efficiency is how well public spending on infrastructure and capital turns into working assets and services. Gaps arise from weak appraisal, political selection, overruns, deferred maintenance and procurement failures. Finance and planning ministries, procurement authorities, audit institutions and lenders hold the decisions.
Where development projects meet hazard and poverty, and which financing layer protects them. Hypothetical projects and design values.
Evidence and capital planning. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.
Projects chosen for political reasons or without cost-benefit analysis may not deliver value. Strong appraisal and transparent selection reduce waste.
Optimistic estimates, scope changes and weak contract management raise costs and delay the benefits projects were meant to bring.
Budget pressure cuts maintenance first, which shortens asset life and raises the cost of replacing assets later.
Collusion and corruption in procurement raise prices and lower quality. Open contracting and audit reduce the risk.
Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.
| Term | Definition |
|---|---|
| Efficiency gap | The difference between actual infrastructure output and what the most efficient peers achieve with the same spending. |
| Project appraisal | Assessment of a project's costs, benefits and risks before a decision to fund it. |
| Cost overrun | The amount by which a project's final cost exceeds its approved budget. |
Each indicator carries its unit, its cadence, the kind of source behind it and the evidence label a value would carry. No values are shown: a programme supplies them under its own authority.
| Indicator | Unit | Cadence | Source type | Label |
|---|---|---|---|---|
| Public investment | percent of GDP | annual | Government finance statistics | OFFICIAL |
| Public investment efficiency gap | percent | periodic | IMF estimates | ESTIMATED |
| PIMA institutional strength scores | score by institution | per assessment | IMF PIMA reports | OFFICIAL |
| Projects with completed cost-benefit appraisal | share of approved projects | annual | Government records | DECLARED |
| Cost overrun on completed projects | percent of original budget | per project | Project completion reports | REPORTED |
| Contracts published under open contracting | share | annual | Open contracting data | OBSERVED |
The topic as a computational graph: named sources feed the methods, an evidence review gates the outputs, and the decisions stay with the authorities that hold them.

Public Finance and Sovereign Debt prepares evidence. The decisions below are taken by the authorities named, under their own rules, and never by the platform.
| Who decides | The question | Evidence this page serves |
|---|---|---|
| Finance and planning ministries | How projects are appraised, selected and funded | PIMA findings and appraisal practice |
| Procurement authorities | How contracts are tendered and managed | Procurement data and audit findings |
| Audit institutions | Whether investment delivered value | Project and spending records |
| Development lenders | Which projects to finance and how to support institutions | Completion reports and assessments |
Public investment management covers planning, project appraisal, budgeting, procurement, implementation and maintenance. Weaknesses at any stage reduce the return on public capital. International assessments of public investment management have found substantial differences in efficiency between countries, and identified institutional practices that are associated with better outcomes, including strong appraisal, multi-year budgeting and transparent procurement.
When governments consolidate their budgets, public investment is often cut first because it is easier to delay than current spending. This can protect short-term budgets at the cost of long-term growth and resilience. Underspending on maintenance allows assets to deteriorate, creating larger costs later and increasing vulnerability to hazards.
Assessing public investment management practices against established frameworks.
Cost-benefit and multi-criteria analysis, drawing on economics and development economics and decision analysis under uncertainty.
Comparing public capital and outcomes across countries, using econometrics.
Project data is often incomplete, benefits are hard to measure, and efficiency comparisons depend on assumptions.
The current service level is R0: information and enquiries. An enquiry receives a reference and names the next step; applications, payments, compute allocations and registrations open only when their team, terms and review capacity exist.
