The demand curve for a good is very unlikely to be perfectly vertical because

A) scarcity and limited income restrict the ability of consumers to afford goods as they become very expensive.
B) as the price of a good rises to high enough levels, the incentive for other suppliers to invent new substitutes for the good increases.
C) consumers generally do not care about the price of the goods they consume.
D) both a and b are true.

As the period for firms to expand output is lengthened, the elasticity of the market supply curve will

A) approach zero.
B) increase.

C) supplier production levels to a change in the price of automobiles.
D) consumer purchases of automobiles to a change in their income.

A) Demand is generally more elastic in the long run than in the short run.
B) Along a single demand curve, demand elasticity decreases as you move down the curve (to lower prices).
C) a flatter demand curve (has a less steep slope) is relatively more elastic than a demand curve that has a steeper slope.
D) All of the above are true.

5. (Answer ONE of the Following Question)

Economists maintain that the price of a product does not affect demand. How can this be true?
National defence is considered a public good because there appear to be no limits to the nonrivalry-in-consumption characteristic, and exclusion of nonpayers is impossible. Are there any other goods that so perfectly meet both public goods criteria?

Essay questions are due at the end of the course. It is strongly recommended that you accumulate your answers as you complete each unit and don't leave them all until the last minute. Please type your responses to the following short answer/discussion questions and short problems. Although your answers need not be lengthy (generally, 1-2 short paragraphs is fine), you should be careful to respond to all parts of the question asked. It is very important that your answers demonstrate that you have made the effort to read the chapter that relates to the question and thoroughly studied the relevant topic. Answers should be submitted in complete sentence and paragraph form, and writing presentation is important. Please remember that late essay questions are NOT accepted. 1. How is a "market" defined? Distinguish between an industry and a market. (1 point) 2. Suppose a market becomes more competitive over time. What happens to the elasticity of demand for a particular firm's good as its market becomes more competitive? (1 point) 3. Why are the monopolist's and the monopolistically competitive firm's demand curves downward sloping while the competitive firm's demand curve is horizontal? (1 point) 4. Why is a perfectly competitive firm's long-run supply curve the same as its marginal cost curve above the average total cost curve? (1 point) 5. Explain why monopolists do not achieve efficiency. (1 point) 6. Another student advocates the forced break-up of large firms, such as Microsoft and AT&T, on the grounds that they have a lot of monopoly power, which they use to charge inefficiently high prices. According to Schumpeter, would breaking apart these gigantic firms guarantee consumers lower prices? Explain. (1 point) 7. Explain why firms should not shut down in the short run until price falls below average variable cost. (2 points) 8. Suppose your economics professor publicly states that she grades on a curve (i.e., the top 10% of the students get an A, the next 20% get a B, the next 40% get a C, the next 20% get a D, and the lowest 10% fail). The whole class could save itself a lot of work by agreeing privately not to study at all for the final exam and just letting the rankings thus far determine the final grades. Why might such an agreement be difficult to maintain and enforce? Which market structure, if any, is this situation most analogous to? (1 point) 9. Why do firms practice price discrimination? Is efficiency affected by price discrimination? If so, how? (1 point)

12) Write out the equation for the arc price elasticity of demand using symbols. Then write out the equation using the following numbers: the price increases from $8 to $10 and the quantity demanded falls from 3 units to 2 units. (Do not calculate the equation.)
