a. Use the information in this table tocalculate total revenue, marginal revenue, and marginal costs. Indicate the profit-maximizing level ofoutput. What market structure is this firm operating in? What would change if the structure were monopolistic competition? OUTPUT PRICE (GH¢) TOTAL COST (GH¢) 1 5 10 2 5 12 3 5 15 4 5 19 5 5 24 6 5 30 7 5 45 b. Under what circumstances would a large size provide an advantage to a firm? How could it serve as a barrier to entry? c. You and your rival must simultaneously decide what price to advertise in the weekly newspaper. If you each charge a low price, you each earn zero profits. If you each charge a high price, you each earn profits of GH¢3. If you charge different prices, the one charging the higher price loses GH¢5 and the one charging the lower price makes GH¢5.i.
