for one person to have a comparative advantage in something even if she has no absolute

advantage in anything. (D) If you and I agree to exchange four cookies for one candy, then I

2. Which one of the following answers is right? (A) Public goods are nonexclusive (available for

3. Which one of the following answers is right? (A) On a straight-line production possibility

frontier, resources are imperfect substitutes. (B) The worst point on a production

possibilities frontier is at the origin, and the best point is the one farthest from the origin (C)

A production possibilities frontier shifts out when society moves from inefficient to efficient

production. (D) At various points along the production possibilities frontier, more of one

good can be obtained with giving up more of the other. (E) Along a bowed-out production

possibilities frontier, the opportunity costs of producing more of one good decreases.

4. Which one of the following answers is wrong? (A) If the price of Pepsi-Cola increases from 40

cents to 50 cents per can and the quantity demanded decreases from 100 cans to 50 cans, then

the value of price elasticity of demand for Pepsi-Cola is –3. (B) A successful advertising

campaign would likely to reduce price elasticity of demand by stressing the uniqueness of the

product. (C) Along a downward-sloping linear demand curve, elasticity is greater at higher

prices. (D) Necessities have an income elasticity of demand that is less than 1 but greater than

zero. (E0When demand is price elastic, total revenue is inversely related to quantity demanded.

5. If an individual’s demand is elastic and price increases, what happens to total utility (TU),

marginal utility (MU), consumer surplus (CS), and total expenditure (TE)? (A) TU increases,

MU decreases, CS decreases, and TE decreases. (B) TU increases, MU increases, CS increases,

and TE decreases. (C) TU decreases, MU increases, CS decreases, and TE increases. (D) TU

decreases, MU increases, CS decreases, and TE decreases. (E) None of the above.

6. Which of the following answers is wrong? (A) For inferior goods, a rise in price causes a

positive income effect and negative substitution effect. (B) Indifference curves are concave due

to the law of both prices triple while income doubles, the budget line rotates counterclockwise.

(D) If you spend your income on orange and apple and the price of apple is three times the price

of orange, for maximization total utility. you will buy apple and orange until the marginal

utility of apple is three times the marginal utility of orange. (E) None of the above.

7. Which of the following answers is right? (A) The marginal rate of technical substitution is the rate

at which one input can be substituted for another without affecting total production costs. (B) At

the point of tangency between an isoquant and an isocost line, the firm must be maximizing revenues.

given resources and technology. (D) The demand curve faced by a monopolistically competitive firms

is less elastic than the demand curves faced by monopolists, but is more elastic than the demand curves

faced by perfect-competitive firms. (E) Monopolistic competition is similar to monopoly, in that firms

face a downward-slopping demand curve, and similar to perfect competition, in that long-run economic

profit is zero.

8. Which of the following answers is wrong? (A) Oligopolists are interdependent, so are more sensitive

to the pricing and output policies of their rivals when all firms produce identical products. (B) Collusion

is easier to achieve and maintain when the firms’ products are homogeneous and their cost structures

are very different. (C) Cartel can equalize each in member firm’s total profit, and decrease competition

and uncertainty. (D) If a monopolist engages in perfect discrimination, the demand curve also becomes

the marginal revenue curve and consumers receive no consumer surplus. (E) None of the above.

9. Which one of the following answers is right? (A) Consider an economy made up of 200 people, 90 of

whom hold job, 10 of them are looking for work, and 12 of whom are retired. The unemployment rate

is 10 percent. (B) Long-term growth in production can be explained by a trade surplus that leads to the

accumulation of foreign exchanges. (C) The market values of daily stock exchange should be included

in the according of GDP. (D) If the official unemployment rate increases in February from January level

because of sluggish sales in the auto industry ,one can conclude that structural unemployment is responsible

for the increase. (E) A higher unemployment benefit may decrease the duration of unemployment.

10. Which of the following answers is wrong? (A)Unanticipated inflation tends to redistribute income

across groups in society. Among the winners are those who borrow at fixed interest rate. (B) As an

expansionary gap is closed in the long run, real GDP declines, compared to in the short run. (C)

Suppose that the marginal propensity to save is 0.25 and that when disposable income is $5.2

trillion, consumption is $5.0 trillion. If disposable income rises to $6 trillion, for fitting the above

data, the level of consumption should be 5.6 trillion. (D) If the price level rises, the aggregate

expenditure line shifts downward：the aggregate demand curve shifts to the left. (E) The potential

output of an economy is the level of output produced when expected price kevel equals the actual price level.

11. Which of the following is wrong? (A) Classical economist believed that if investment were greater

than saving, the interest rate would rise, causing saving to increase and investment to decrease until

the two were equal. (B) If checking deposits increase by $6,000 after all rounds of the money-

creation process when the Fed buys $1,200 worth of U.S. government securities constitutes an

expansionary policy because it raises the amount of total reserves in the banking system. (D) The

demand for money varies directly with both the price level and the level of real GDP. But the

U.S, so banks will keep it at a minimum level, which will increase banks’ profits but decrease

liquidity. (E) Crowing out effect means that increases in government purchases cause interest rate
