Market structure - Essay Example harmonise to Baumol and Blinder (2011 p. 200), such a grocery store must satisfy four conditions. First, the market has many small firms and customers such that no participants ar large enough to have market power to affect the price of a product. If one producer reduces the price, there would be no effect on the market since the producer is negligible compared to the whole market. This condition rules out the possibilities for collusion or trade associations distri scarcelyively firm acts independently (Tucker, 2010). Secondly, all the suppliers sell a homogeneous product there are no close substitutes (McEachern, 2011). As such, the consumers sully products from any seller since the products are the same thus competition is very powerful. The conduct wrap is perfectly elastic hence if a seller increases the price of the product, customers shift to buy competitors products. The firms have no choice but to meet and not exceed the price charged by others hence are price takers (Baumol & Blinder, 2011 p. 201). Thirdly, there are no barriers to entry or exit in the market. Barriers to entry may be in form of legal, technical or cost advantage but in a perfectly competitive market, any seller willing to enter the industry can do so to take advantage of economical profits and provide an identical product (p. 200). The new entrant is at the same level with the old firms there are no advantages for existing firms so the new firm can compete effectively. Lastly, the unconditioned buyers and sellers have perfect information regarding the price and quality of products in the market. As a result, there is no need for advertising as it would have no effect the customers know where to buy their products and besides, all products are identical and the price is determined by the market. According to Landsburg (2011), in a perfectly competitive market there are no transaction costs and perfect factor mobility. This enables the market t o adjust hence in case of changing market conditions. Q2 Price and Output Decisions of a Perfectly Competitive Market As noted above, there are infinite buyers and sellers in the market such that none has an effect on price. The price in such a market is determined by forces of supply and demand hence the sellers are price takers. Sexton (2012) argues that since the market price is given, the only decision that firms have to make is determining the level of output that would maximize profit. The capitulum firms should ask themselves as asserted by McEachern (2011 p. 176) is how much should I produce? He notes that firms aim at producing a quantity at which total tax revenue enhancement is higher than total cost by the greatest amount. The profit maximizing output in a perfectly competitive market occurs where marginal revenue (MR) is equal to marginal cost (MC) MR=MC therefore the firms are seen to allocate resources efficiently. A perfectly competitive firm has a horizontal dem and curve thus it can sell as much quantity as it wants at the given market price. Whether the firm increases its output or not, the price trunk the same as there are many sellers. It too does not have to reduce the price so as to attract demand as it would lead to loss of revenue for the firm (Baumol & Blinder, 2011). Since total revenue is the output multiplied by the price, the average revenue is the same as price. The firm is also a price taker hence the marginal revenue is equal to
