325 Keep These Things In Mind The key points about Perfect Competition: - All firms produce identical output (corn is corn). - There are innumerable small firms in the industry and no one firm can have any influence over market price. - The firms are price takers. The price for their output is established in the market by the interaction of all buyers and and all firms. - Each firm can sell all the output they choose at only the existing market price- horizontal demand. - Each firms produces at the point where MR=MC. - Firms can make economic profits in the short run. This means they are receiving a price greater than the average cost of production. - If this happens, new firms will enter the industry- there are no barriers to entry. When new firms enter, supply increases and price falls. Price keeps falling until all firms are just receiving a normal rate of return (no economic profits). “Original document by Peter Turner licensed CC BY”
