Money is one of the important concepts, This section talks about money from the perspective of microeconomics.when people exchange goods and services without using money, this is called barter. "I'll cook dinner if you'll do the dishes" is an example of barter. Imagine an economy in wich i can sell services as a consultant to banks, but what i want is to buy a new suit. the clothing store that sell suits does not have any use for my services as a banking consultant. i sell consulting services for money, and i buy a suit using money. money serves as a medium of exchange. the bank does not sell suits. how can barter work?
No barter is not just exchange of goods for services but also exchange of goods for goods. In the history when money was not yet invented or in remote places where people do not have money they do barter like selling a piece of woodcraft for clothing, chicken for grains, vegetable of other items or offer a service for a sack of grains. There was a topic before that talked about the disappearance of money or in the event were there will be no money, so barter will happen.
