Explain the meaning of investment in an economy in terms of capital formation. Discuss the factors to be considered while designing a concession agreement between a public entity and a private entity.

In short

Investment is the addition to an economy's productive capital stock, measured as capital formation, while a sound concession agreement allocates risk, tariff, tenure, performance and exit terms fairly. Delhi Airport Metro Express v. DMRC, reversed by the Supreme Court in 2024, shows the cost of vague termination clauses.

Model answer

Ghissu Editorial · Verified 4 Oct 2026

Introduction
Investment means the addition to an economy's stock of productive capital, recorded as capital formation, not the mere purchase of shares or gold. Much of India's infrastructure investment now flows through concession agreements, so their design shapes growth.
Investment as Capital Formation
•

Flow adding to stock

Gross Capital Formation is fixed capital formation in machinery, buildings and infrastructure, plus inventories and valuables; net formation deducts depreciation.

•

Real versus financial

Buying an existing share only transfers ownership; it counts as capital formation only when it creates a new asset.

•

Link to growth

In the Harrod-Domar model, growth equals the investment rate divided by the ICOR.

Factors in Designing a Concession Agreement
•

Risk allocation

Construction and operation risks rest with the concessionaire, land and clearances with the authority, as the Kelkar Committee (2015) stressed.

•

Tenure and tariff

The concession period and indexed user charges must allow cost recovery, with Viability Gap Funding for economically sound but financially weak projects.

•

Performance and handback

Service standards, an independent engineer and handback conditions protect asset quality.

•

Termination and disputes

Clear termination payments avert disputes like Delhi Airport Metro Express v. DMRC, where the Supreme Court set aside an upheld award in 2024.

•

Regulators and tribunals

Independent sector regulators and the Kelkar Committee's proposed PPP adjudication tribunal would speed resolution, while Hybrid Annuity models and NaBFID finance reduce risk.

Conclusion
Investment builds the capital stock behind growth, and balanced concessions that price risk fairly can crowd in the private capital Viksit Bharat 2047 needs.
