Expert Solution & Answer

Explanation of Solution

If the increase in production results in a decrease in average total cost, then in such a case, there will be a downward sloping curve of average total cost. Therefore, it is more profitable for a producer to produce more if the average total cost is decreasing with the increase in production.

The economies of scale are mostly enjoyed by the already existing firm, who have decreased its cost of production by using its resources in a most efficient way and by reducing its average total cost. The new firm cannot use its resources with that much efficiency and it cannot even reduce its cost of production, as much already existing firm can. Thus, a new firm cannot compete with the already existing firm and cannot gain economies of scale. Therefore, entry of new firm is restricted because of economies of scale.

"Whether the regulator sells or gives away tradeable emission permits free of charge, the quantities of emissions produced by firms are the same." Assume that there are n identical profit-maximising firms where profit for each firm is given by π(e) with л'(e) > 0; π"(e) < 0 and e denotes emissions. Individual emissions summed over all firms gives E which generates environmental damages D(E). Show that the regulator achieves the optimal level of total pollution through a tradeable emission permit scheme, where the permits are distributed according to the following cases: Case (i) the firm purchases all permits; Case (ii) the firm receives all permits free; and Page 3 of 5 ES30031 Case (iii) the firm purchases a portion of its permits and receives the remainder free of charge.
