What is money and how it can be used?
Money is a medium of exchange which facilitates transactions between two parties.
A barter system is that in which goods are exchanged (one good for other) by parties on both sides but there can be a problem of double coincidence of wants in this. It means a party wanting the good doesn’t necessarily mean another party would also want that good.
So intermediary money can be used to buy a good and the other party can use the money to buy the good they want.
DEMAND FOR MONEY
Money is the most liquid asset. If you keep money in bank instead of cash it might give you interests.
Transaction motive is used to exchange goods. As it goes from one person to other person and then from second to third it keeps changing hands. The number of times money changes in a unit period is velocity of circulation of money.
Where T is the total value of money, k is positive fraction and Md is the demand for money.
So velocity is 1/k.
Where P is price and Y is GDP deflator.
BANKING WITH MONEY
When a person sells goods and gets money in exchange, he/she can put the savings in the bank.
