the market's place within the distribution system. This leads to two broad classes of market, namely retail market or wholesale markets. The economist, Alfred Marshall classified markets according to time period. In this classification, there are three types of market; the very short period market where the supply of a commodity remains fixed. Perishables, such as fruit, vegetables, meat and fish fall into this group since goods must be sold within a few days and the quantity supplied is relatively inelastic. The second group is the short period market where the time in which the quantity supplied can be increased by improving the scale of production (adding labor and other inputs but not by adding capital). Many non-perishable goods fall into this category. The third category is the long-period market where the length of time can be improved by capital investment. Other ways to classify markets include its trading area (local, national or international); its physical format or its produce. Major physical formats of markets are: Bazaar: typically a covered market in the Middle East Car boot sale - a type of market where people come together to trade household and garden goods; very popular in the United Kingdom Dry market: a market selling durable goods such as fabric and electronics as distinguished from "wet markets" E-commerce: an online marketplace for consumer products which can be sold anywhere in the world Indoor market of any sort Marketplace: an open space where a market is or was formerly held in a town Market square in Europe: open area usually in town centre with stalls selling goods in a public square Public market in the United States: an indoor, fixed market in a building and selling a variety of goods Street market: a public street with stalls along one or more sides of the street Floating market: where goods are sold from boats, chiefly found in Thailand, Indonesia and Vietnam Night market: popular in many countries in Asia, opening at night and featuring much street food and a more leisurely shopping experience. In Indonesia and Malaysia they are known as pasar malam Wet market (also known as a public market): a market selling fresh meat, fish, produce, and other perishable goods as distinguished from "dry markets" Markets may feature a range of merchandise for sale, or they may be one of many specialist markets, such as: Animal markets (i.e. livestock markets) Antique
