Explanation:

John Maynard Keynes was a British economist born on the 5th of June, 1883 in Cambridge, England. He was famous for his brilliant ideas on government economic policy and macroeconomics which is known as the Keynesian theory. He later died on the 23rd of April, 1946 in Sussex, England.

The Keynesian link between the money market and the goods and services market is indirect. Changes in the money market must affect the investment market before the goods and services market is affected.

According to the Keynesian Transmission Mechanism, the link between the money market and the goods and services market is indirect; because at first, short-term interest rates are lowered by an increase in the supply of reserves and then with time both the bond and bank loan rates falls. Consequently, this would make investments and aggregate demand (AD curve shifts rightward) to rise or increase as a result of the low cost of capital for investors and by extension it boost the level of production or quantity of output (real gross domestic product or Real GDP).

This ultimately implies that, the interest rates affects the real and costs of capital (monetary changes).
