9 A competitive firm experiences a shift in costs of production that decreases marginal costs at all levels of output. What does this situation mean for the firm? A Producing less at any market price will off-set marginal cost. B The firm's demand curve will also shift to the left. Expanding output levels at any given price will be profitable. DO The firm's marginal cost curve will shift to the left.

Which of the following statements is TRUE? O Assume that wheat farmers operate in a competitive industry. A decrease in the cost of producing wheat will lead to greater profits for wheat farmers in the long run than in the short run. O A rational decision maker will never take sunk costs into account. A change in price will have no effect on total revenue when the own-price elasticity of demand is zero. O (From the perspective of the consumer) When the fixed fee increases, the quantity consumed will always decrease.
8. Short-run and long run effects of a shift in demand Suppose that the tuna industry is in long-run equilibrium at a price of $5 per can of tuna and a quantity of 350 million cans per year. Suppose that WebMD daims that a protein found in tuna will increase your expected lifespan by 2 years. WebMD's claim will cause consumers to demand more PRICE (Dollars per cani producing more tuna and earning positive profit Shift the demand curve, the supply curve, or both on the following graph to illustrate these short-run effects of WebMD's claim. ? 0 tuna at every price. In the short run, firms will respond by Supply Demand 70 140 210 200 350 420 400 560 630 700 QUANTITY (Millions of cans) Demand -0 Supply
Assume that marginal revenue equals rising marginal cost at 100 units of output. At this output level, a profit-maximizing firm's total fixed cost is $600 and its total variable cost is $400. If the price of the product is $8 per unit, the firm should produce O less than 100 units of output. O The amount is impossible to determine from the information given. O 100 units of output. O more than 100 units of output.
