When the marginal-cost curve lies below the marginal-revenue curve     a. the firm cannot improve its profit since revenue is already greater than cost.   b. marginal revenue is greater than marginal cost, and the firm should therefore increase production to increase profits.   c. marginal revenue is greater than marginal cost, and the firm should therefore decrease production to increase profits.   d. marginal revenue is less than marginal cost, and the firm should therefore decrease production to increase profits.   e. it is not possible for this firm to increase profits since it is failing to operate at an efficient point.

1. The following table shows the cost information for a perfectly competitive firm.   Production Total variable cost (RM)0 01 1002 1503 2104 2905 4006 5407 7208 950 a. If the total fixed cost of the firm is RM300, calculate total cost, average cost and marginal cost.     b. If the market price is RM200, calculate the firm total revenue, and total profit/loss     c. Determine the level of production that will maximise the firms profits.

Question 28 When economic profit is positive in a perfectly competitive industry, market a. supply will increase in the long run causing firm marginal revenue to rise. b. supply will increase in the long run causing firm marginal revenue to fall. c. supply will decrease in the long run causing firm marginal revenue to fall. d. demand will increase in the long run causing firm marginal revenue to rise. e. supply will decrease in the long run causing firm marginal revenue to rise.

If a firm's marginal revenue is smaller than its marginal cost, then the firm should a. increase output to increase profit. b. decrease output to increase profit. c. keep output the same. d. collect additional information before taking any action.

Marginal profit is negative when A. output exceeds the profit-maximizing level. B. total cost exceeds total revenue. C. marginal revenue is negative. D. profit is negative.
