seller concentration

an element of MARKET STRUCTURE that denotes the number and size distribution of suppliers in a given MARKET. Market theory predicts that MARKET PERFORMANCE will differ according to whether there are many suppliers in the market, each accounting for only a small fraction to total supply (PERFECT COMPETITION), or only a few suppliers, each accounting for a substantial proportion of total supply (OLIGOPOLY) or a single supplier (MONOPOLY).
