O productive efficiency will occur in both the short run and long run, a desirable economic property of markets. many smaller sized firms can produce the good or service at lower cost per unit than larger sized firms, thus large firms fail in the long run. the demand curve for each firm is not going to be purely elastic, because products are at least slightly different than potential rival firms' product and/or there may be some consumer brand loyalty. Firms in both types of markets eventually will be broken up by government anti-trust laws and regulations. MacBook Pro く※ G Search or type URL 6 7 8. 3 4. W Earrow_forward
