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?
Barter works well for the people who are willing to exchange for things that you have. If they are not willing, find someone who is, exchange it for something else and offer that for what you want. But the problem with barter is that it is not universal and it is not constant. One might percieve that what you're offering isn't of value much like offering a heater in the middle of the desert. Money makes ir possible to directly exchange it for something else.
