Barter is a system of exchange where goods or services are directly traded without using money. It is usually bilateral but may be multilateral and is used in times of monetary crisis. Ethnographic studies have shown that no society has used barter without any other medium of exchange or measurement. Barter's limitations include the need for double coincidence of wants, absence of a common measure of value, and indivisibility of certain goods.
# Money
Money has several advantages over the barter system, including serving as a medium of exchange, measure of value, store of value, and standard of deferred payments. It has simplified borrowing and lending operations and encouraged capital formation. Money is demanded for three motives: transaction, precautionary, and speculative. The Mool-mantra of this concept is to wipe-out the liquidity crisis by helping people trade, swap, and replace anything for free.
