Money is a powerful weapon
Money is any item or medium of exchange that is accepted by people for the payment of goods and services, as well as the repayment of loans. Money makes the world go 'round. Economies rely on money to facilitate transactions and to power financial growth. Typically, it is economists who define money, where it comes from, and what it's worth. Here are the multifaceted characteristics of money.The basic function of money is to enable buying to be separated from selling, thus permitting trade to take place without the so-called double coincidence of barter. In principle, credit could perform this function, but, before extending credit, the seller would want to know about the prospects of repayment. That requires much more information about the buyer and imposes costs of information and verification that the use of money avoids.If a person has something to sell and wants something else in return, the use of money avoids the need to search for someone able and willing to make the desired exchange of items. The person can sell the surplus item for general purchasing power—that is, “money”—to anyone who wants to buy it and then use the proceeds to buy the desired item from anyone who wants to sell it.The total quantity of money in the economy at any one time is called the money supply. Economists measure the money supply because it affects economic activity. What should be included in the money supply? We want to include as part of the money supply those things that serve as media of exchange. However, the items that provide this function have varied over time.
