Differentiate between demand-side and supply-side constraints on corporate investment, with reference to firm size in India.

A firm builds capacity only when expected demand justifies it and capital is available at an acceptable cost. Demand-side constraints depress expected returns; supply-side constraints raise the cost or availability of financing and inputs. In India the binding constraint differs systematically by firm size.

Conceptual distinction

• Demand-side: subdued consumption, spare capacity, uncertain order books — investment is deferred even when credit is cheap.
• Supply-side: cost of capital, collateral and credit access, land, clearances, skilled labour — these raise the hurdle rate for an otherwise viable project.

Large firms: demand is the binding constraint

• Balance sheets are repaired. RBI's study of the private corporate sector shows net profits rising to about ₹7.1 trillion in 2024-25 from ₹2.5 trillion in 2020-21, with net profit margin improving to 10.3% [1] — profitability and financing are not the bottleneck.
• Yet intentions exceed realisation: the government's forward-looking survey records intended capex of about ₹4.88 trillion for FY26 against ₹6.56 trillion for FY25 [2], while private-sector GFCF stood near 26.4% of GDP (2023) [3]. Cash-rich firms are waiting for capacity utilisation and demand visibility, not for lower rates.
• Hence the 2019 corporate tax cut and the low-rate phase produced no durable revival — a supply-side lever aimed at a demand-side problem.

Smaller firms: supply is the binding constraint

• MSMEs face thin collateral, higher risk premia and costlier NBFC borrowing, so policy transmission reaches them weakly — the reason RBI mandated external benchmark-linked (EBLR) floating-rate MSME loans from October 2019 [4].
• Delayed receivables, land and clearance frictions compound the credit gap.

The two constraints therefore demand different instruments: sustained public capital expenditure to crowd in demand for large firms, and credit guarantees, receivables discounting and clearance reform for smaller ones. A calibrated mix of both — rather than tax or rate cuts alone — is what can restore corporate investment to its pre-2016 share of GDP.
