Economies abound in markets. A market consists of all potential customers sharing a particular need or want who might be willing and able to engage in exchange to satisfy that need or want. Each nations economy and the whole world economy consist of complex interacting sets of markets that are linked through exchange processes. The concept of markets brings us full circle to the concept of marketing. Marketing means working with markets to actualize potential exchanges for the purpose of satisfying human needs and wants. Marketing is a social and managerial process by which individuals and groups obtain what they need and want through creating, offering and exchanging products of value with others.
