Problem 1. Think what is the cost of one can of Coca-cola. First try to figure out what is the
accounting cost, i.e. the monetary cost. Next think what would be a total economic cost of
producing one can of Coca-cola. Try to provide some examples.
Problem 2. Explain whether each of the following government activities is motivated by a concern
about equality or a concern about efficiency. In the case of efficiency, discuss the type of market
failure involved:
a. instituting laws against driving while intoxicated
b. read the following article and analyze the described policy.
c. setting minimum wage policy.
Problem 3. Jana has 1,200 CZK to spend and wants to buy either training shoes or a new mp3
player to listen to music while working out. Both the shoes and the mp3 player cost 1,200 CZK, so
she can only buy one. This illustrates the basic concept that
a. People respond to incentives.
b. people face trade-offs.
c. rational people think at the margin.
d. Governments can sometimes improve market outcomes.
Problem 4. The phenomenon of scarcity stems from the fact that
a. most economies’ production methods are not very good.
b. in most economies, wealthy people consume disproportionate quantities of goods and services.
c. governments restrict production of too many goods and services.
d. resources are limited.
Problem 5. A likely effect of government policies that redistribute income and wealth from the
wealthy to the poor is that those policies
a. enhance equality.
b. enhance efficiency.
c. increase the reward for working hard.
d. All of the above are correct
Problem 6. A certain state legislature is considering an increase in the state gasoline tax.
Representative Campbell argues that an increase in the gasoline tax would harm low-income drivers
disproportionately. Representative Richards responds by saying that low-income drivers own
smaller cars that use less gasoline, and that low-income drivers therefore would not be harmed
disproportionately.
a. Representative Campbell’s argument is based primarily on efficiency, while Representative
Richards’ argument is based primarily on equality.
b. Representative Campbell’s argument is based primarily on equality, while Representative
Richards’ argument is based primarily on efficiency.
c. Both representatives’ arguments are based primarily on efficiency.
d. Both representatives’ arguments are based primarily on equality.
Problem 7. Suppose the state of Wyoming passes a law that increases the tax on cigarettes. As a
result, smokers who live in Wyoming start purchasing their cigarettes in surrounding states. Which
of the following principles does this best illustrate?
a. People respond to incentives.
b. Rational people think at the margin.
c. Governments can sometimes improve market outcomes.
d. Markets are usually a good way to organize economic activity.
Problem 8. Nearly 30 US states use the death penalty exclusively for the crime of murder. At the
same time, only few states execute death penalty against such crime as rape. Knowing that people
(including those who commit crime) think at the margin, could you explain the observed
phenomenon?
Problem 9. Suppose you observe the amount of chocolate bars that Paul consumes for a given price.
The schedule is the following:
PRICE (CZK) AMOUNT OF CHOCOLATE BARS
0 10
10 9
30 7
60 4
80 2
90 1
Draw a relationship between the price and the amount of cholate bars that Paul consumes. Put price on
the vertical axis and the amount on the horizontal axis. Does the relationship seem linear? Assume that
the schedule represents a linear curve, what would be its slope?
Problem 10. A rational decision- maker takes an action if and only if
a)the marginal benefit of the action exceeds the marginal cost of the action.
b) the marginal cost of the action exceeds the marginal benefit of the action.
c) the marginal cost of the action is zero.
d) the opportunity cost of the action is zero.
Problem 11. Define opportunity cost. What is the opportunity cost to you of attending college?
What was your opportunity cost of coming to class today?
Problem 12. You have the afternoon free. You have a choice between going to the movies with a
friend or studying economics for three hours. If you go to the movies, you will spend $8.00 on a
ticket and $4.50 on popcorn. If you choose to study economics for three hours, you will raise your
exam grade by 10 points.
a) What is your opportunity cost of going to the movies?
b) What is your opportunity cost of studying at home?
Explain your answers.
Problem 13. Maria quits her job at a bank, which pays 300,000 CZK a year, to enroll in a two-year
graduate program in Economics. Her annual school expenses are 240,000 CZK for tuition and fees.
What is her opportunity cost of attending the two-year graduate program?
