Measures to Stimulate Private Investment

The level of employment in an economy is directly affected by changing levels of investment. During a depression, private firms reduce investment due to low expected profitability, leading to falling output and rising unemployment. To break this cycle, it becomes essential to encourage private investment through various fiscal, monetary, and structural measures.
The following nine measures are discussed below, based on the views of Keynes and other major economists like Hansen, Lerner, Klein, and Harris.

• Reducing taxes on corporate profits increases MEC (expected rate of return), making investment more attractive.​
• Supported by Hansen, Lerner, Klein.​
• Limitation: Government may impose indirect taxes to cover revenue loss, reducing effective demand.​​

• Lower interest rates make borrowing cheaper → more investment when MEC > interest rate.​
• Keynes's view: In the General Theory, he argued investment is not interest-elastic during depression — low rates alone won't work if business confidence (MEC) is too low.​
• Further limited by the liquidity trap — at very low rates, people hoard cash instead of investing.​

• Government directly spends on public works (dams, housing, infrastructure) to fill the gap left by declining private investment.
• Works through the multiplier effect — each rupee spent generates multiple rupees of income.​
• Keynes called this compensatory public spending — the government acts as a "balancing factor" during depression.

• Classical view: Lower wages → lower costs → higher profits → more investment.​
• Keynes's objection: Wages have a dual nature — they are both a cost to producers AND income to workers. Cutting wages reduces effective demand, hurting investment overall.​
• Keynes, Hansen, Harris, Klein all opposed wage cuts.

• Price fluctuations create uncertainty → lower MEC → less investment.​
• Government uses a price support policy — buying commodities when prices fall, selling when prices rise — to stabilise the business environment.​

• Prof. Klein argued that non-profit scientific research opens up new fields of investment that private firms wouldn't discover alone.​
• Innovation creates new industries and raises demand for capital.

• Competitive markets force firms to innovate and invest in cost-reducing technologies.​
• Monopolies suppress new entry and hold back investment.

• A temporary, one-time injection of government spending to kickstart private investment via the multiplier.​
• Like pouring water into a dry hand-pump to get it flowing — government spending "primes" the economy.​
• Different from compensatory spending (which is large-scale and sustained); pump priming is meant to stimulate, not replace private investment.​

• Instability of prices is another factor that brings about instability of private investment.
• A certain degree of price stability is considered essential for promoting private investment.​
• To realise the objective of stability of prices, the policy of price support is recommended.​
• Under this policy, the government sets a floor price (minimum price) for key commodities. If market prices fall below this level, the government buys the surplus at the support price to prevent further decline.
• This shields producers from sharp price drops, maintains income stability, and creates a predictable business environment that encourages long-term investment.

• Tax concessions on profits increase MEC and encourage investment.
• Lower rate of interest may stimulate investment, though Keynes stressed limited responsiveness.
• Government spending (pump-priming) boosts income and induces private investment through the multiplier.
• Price stability and price support policies reduce uncertainty and promote investment.
• Research, innovation, and competition (reducing monopoly power) open new investment opportunities.
