Final answer:
The significance of money in an economy and its role as a medium of exchange, measure of value, and store of value.
Step-by-step explanation:
Money for the sake of money is not an end in itself. According to Ambrose Bierce, money is a "blessing that is of no advantage to us excepting when we part with it." Money is what people regularly use when purchasing or selling goods and services, and thus both buyers and sellers must widely accept money. Money serves as a medium of exchange, a measure of value, and a store of value. The existence of money provides enormous benefits to an economy, making transactions easier and allowing people to find employment and purchase the goods they need.
