Some firms will exit the industry, which will push the price further down until all firms make only normal profits in the short run. (c) The market price to rise, which will lead to firms making supernormal profits in the short run. New firms will enter the industry, which will push the price down until all firms make only normal profits. (d) The market price to fall, which will lead to firms making losses in the short run. Firms will exit the industry, which will push up the price until the remaining firms make normal profits.
