Keynesian Theory: Interest Rates And Investment Insights

Keynesian economics advocates for countercyclical policies, meaning that during economic downturns, the government and central banks should implement expansionary policies to boost aggregate demand and stimulate economic activity. Lowering interest rates is one of the primary tools used to achieve this goal. When the economy is struggling, the Bank of England may lower interest rates to make borrowing cheaper, encourage spending, and stimulate investment. Keynes believed that the long-term rate of interest was in the gift of policymakers, and that a very great fall in the long-term rate of interest could be achieved through deliberate policy action.

Keynes's theory states that an increase in the money supply leads to a drop in interest rates and an increase in investment

Keynes's theory also attributes unemployment to wage stickiness and treats saving and investment as governed by independent decisions: the former varying positively with the interest rate, the latter negatively. The velocity of circulation is expressed as a function of the rate of interest. He interpreted his treatment of liquidity as implying a purely monetary theory of interest.

Keynes's younger colleagues of the Cambridge Circus and Ralph Hawtrey believed that his arguments implicitly assumed full employment, and this influenced the direction of his subsequent work. On the basis of Keynes’s theory, which emphasised corporate investment expansion and animal spirits, the global financial crisis really began at the end of the millennium.

Keynes's theory states that the rate of interest determines the level of investment

Keynes's theory treats saving and investment as governed by independent decisions: the former varying positively with the interest rate, the latter negatively. The velocity of circulation is expressed as a function of the rate of interest.

The incentive to invest arises from the interplay between the physical circumstances of production and psychological anticipations of future profitability. However, once these things are given, the incentive is independent of income and depends solely on the rate of interest.

Keynes designates its value as a function of r as the "schedule of the marginal efficiency of capital". This is shown as a blue curve in a graph, with the red curves showing what the propensities to save are for different incomes. The income corresponding to the equilibrium state of the economy is the one for which the implied level of saving at the established interest rate is equal to the level of investment.

The rate of interest determines the level of investment Î through the schedule of the marginal efficiency of capital. The red curves in the same diagram show what the propensities to save are for different incomes Y. The income Ŷ corresponding to the equilibrium state of the economy must be the one for which the implied level of saving at the established interest rate is equal to Î.

Keynes's theory states that the demand for money depends on income as well as on the interest rate

According to Keynes, if people believe that interest rates are going to rise, they reduce their money holdings to invest in bonds, expecting their price to increase. However, if they think rates will fall, they hold on to money expecting bond prices to drop. An increase in the money supply, according to Keynes's theory, leads to a drop in the interest rate and an increase in the amount of investment that can be undertaken profitably, bringing with it an increase in total income.

Keynes's younger colleagues of the Cambridge Circus and Ralph Hawtrey believed that his arguments implicitly assumed full employment, and this influenced the direction of his subsequent work. Critics argue that investment behaviour is affected by numerous other factors, including but not limited to an individual's risk appetite, market conditions, and overall economic climate. For instance, during an economic downturn, individuals may still opt for lower-yield, safer assets despite declining interest rates.
