Trade

Trade is the exchange of goods or services among two or more parties. In its
original form trade had to be negotiated through barter and the exchange of
goods and services of a recognized equal value that was wanted by both
parties. Modern trade is generally negotiated through the use of a medium of
exchange, i.e. money, and rarely through barter: as a result one can
separate buying and earning or selling. The invention of money greatly
simplified and promoted the development of trade.
