1.i) Assuming you are the managing director of a firm that produces goods: A,B and C .The price elasticity of demand for A is 1.2, for B it is 1.oo and C is 0.75. It is known that he's firm is experiencing serious cash flow problems and you have to increase total revenue as soon as possible. If you were in a position to set the prices for these goods, what would be your pricing strategy for each product ii) price falls from N$ 16 to N$ 12 per bottle and demand rises from 200 to 300 per bottle.calculate the PED using midpoint formula Output prices average (total)cost Total cost marginal cost Total profit/loss 10 10 -108 20 10 4 -48 30 10 5 3 40 10 6.20 40 50 10 8 60 60 10 10 60 2. i) fill in the gaps ii)in which market structure doess Johnson Electronics (Pty)Ltd operate? iii)what level of output maximizes the firms profit
Which of the following offers the best explanation of why “marginal revenue equals marginal cost” is the rule that indicates the profit-maximizing output level? a. If output were reduced from the profit-maximizing level, then the firm would be gaining marginal revenue that exceeds marginal cost, and thus increasing the level of profit. b. The marginal revenue is equal to the marginal cost at all levels of output for a perfectly competitive firm. c. If output were increased from the profit-maximizing level, then the firm would be gaining marginal revenue that is less than the marginal cost incurred in producing this additional unit, and thus reducing the level of profit. d. Because the firm colludes with other similar firms to set price equal to marginal cost.

His record company's marketing department determines that the demand for the CD is as follows: Price Number of CDs $24 10 000 22 20 000 20 20 30 000 18 40 000 16 50 000 14 60 000 The company can produce the CD with no fixed cost and a variable cost of $5 per CD. a.

3. Consider the perfectly competitive markets for bottled water in two cities, A and B. Both have a downward-sloping demand curve and upward-sloping supply curve, and each market is currently in long run equilibrium at the same price. The demand curves are similar, but in city A the supply curve is more price elastic than in city B. a) There's a shock: an accident causes the tap water in the area to become undrinkable. In two diagrams, one for each city, compare the effect on price and quantity traded in the two cities, assuming that a new equilibrium is reached. Explain your diagrams. b) Following on from your answer to a), explain what would happen in the model to the number of suppliers and their profitability, in each of the short run and the long run.
1. Assume a perfectly competitive market. Draw the average total cost, average variable cost, marginal cost, and marginal revenue curves for a good. Determine the profit-maximizing level of output given that the price of the good is above the minimum average variable cost but below the minimum average total cost Is the profit at the chosen price point positive, zero, or negative ? Shade the area representing profit
