1) In constructing models, economists:
A.make simplifying assumptions.
B.include all available information.
C.must use mathematical equations.
D.attempt to duplicate the real world.
2) Suppose there are only two planets in the universe, Zenope and Zuranda. On each
planet, its inhabitants consume two productscoffee and fried chicken. Each planet has
an equal population. Producing solely coffee, Zenope can produce 50 units of coffee,
while Zuranda can produce 80 units of coffee. Producing solely fried chicken, Zenope
can produce 25 units, while Zuranda can produce 30 units.
(a)Which planet has the absolute advantage in coffee? In fried chicken?
(b)Which planet has the comparative advantage in coffee? In fried chicken?
3)

B.in the 0P1 price range.
C.in the P2P4 price range.
D.only at price P2.
4) Overproduction of farm products in the European Community has been primarily the
result of:

B.Subsidies to farmers in the European Community
C.Increasing world trade in agricultural commodities

5) At any level of a mining firm's output, total cost will be equal to extraction costs:

B.Minus user costs
C.Times user costs
D.Divided by user costs

In the diagram, the prices of Coke and popcorn respectively are:
A.$.50 and $1.00.
B.$1.00 and $.50.

future change in the value of the commodity, then the buyer or seller is:
A.Logrolling
B.Hedging
C.Allotting
D.Bolstering
8) A consumer is making purchases of products Alpha and Beta such that the marginal
utility of product Alpha is 30 and the marginal utility of product Beta is 40. The price of
product Alpha is $5 and the price of product Beta is $10. The utility-maximizing rule
suggests that this consumer should:
A.Increase consumption of product Beta and decrease consumption of product Alpha
B.Increase consumption of product Beta and increase consumption of product Alpha
C.Increase consumption of product Alpha and decrease consumption of product Beta
D.Make no change in the consumption of Alpha or Beta
9) According to the paradox of voting:
A.public goods that cost more than the total benefits they confer may get produced
under majority voting.
B.trading of votes may either add to or subtract from economic efficiency.
C.the median voter decides what public goods all voters should have.
D.majority voting fails under some circumstances to make consistent choices that
reflect the community's underlying preferences.
10) In 1975, McDonald's introduced its Egg McMuffin breakfast sandwich, which
remains popular and profitable today. This longevity illustrates the idea of:
A.opportunity cost.
B.upsloping supply.
C.consumer sovereignty.
D.specialization.
11) Assume you are spending your full budget and purchasing such amounts of X and Y
that the marginal utility from the last units consumed is 40 and 20 utils respectively.
Assume (a) the prices of X and Y are $8 and $4 respectively; (b) it takes 3 hours to
consume a unit of X and 1 hour to consume a unit of Y; and (c) your time is worth $2
per hour. You:
A.should substitute X for Y until the marginal utility per hour is the same for both
products.
B.are consuming X and Y in the optimal amounts.
C.should consume less of Y and more of X.
D.should consume less of X and more of Y.
12) Answer the question on the basis of this table showing the marginal benefit that a
particular public project will provide to each of the three members of a community. No
vote trading is allowed.
If the tax cost of this proposed project is $300 per person, a majority vote will:
A.defeat this project and resources will be underallocated to it.
B.pass this project and resources will be allocated efficiently.
C.pass this project and resources will be underallocated to it.
D.defeat this project and resources will be overallocated to it.
