According to Keynes, interest is a payment for the use of money. He argued that interest is a reward for saving, and that it is necessary to encourage people to save in order to finance investment. Keynes also argued that interest rates are determined by the demand for and supply of money. When the demand for money is high, interest rates will be high. When the supply of money is high, interest rates will be low.
