Q.State any four essential features of a market.

A market must have certain basic elements present together before genuine exchange can take place between buyers and sellers.

A market is only said to exist when several conditions are present together. First, there must be a commodity or service of value that is the subject of exchange — without something to trade, there is nothing for a market to organise. Second, a market needs buyers and sellers willing to transact; the numbers on each side may vary from very few to millions. Third, there must be a place, area, or medium through which the buyers and sellers make contact — this can be a physical location, a region, or a communication channel such as a telephone or an online platform. Fourth, exchange happens at a price, which both sides accept, whether it is arrived at through bargaining, a posted price list, or an auction. A fifth commonly added feature is free interaction and competition among the participants, which is what allows a genuine market price to emerge rather than an arbitrarily fixed one. Any four of these features together capture the essential character of a market.

Students sometimes list 'a shop' or 'a building' as an essential feature, which is wrong under the wider commerce definition of market. Always phrase the place/contact feature broadly enough to include non-physical arrangements such as telephone or online contact.
