Week One: Fundamentals of Microeconomics
Objective: Differentiate between macroeconomics and microeconomics. 1. Macroeconomics is
the study of individual choice and how that choice is influenced by economic forces the study of the pricing policies of firms and the purchasing decisions of households the study of aggregate economic relationships an analysis of economic reality that proceeds from the parts to the whole
2. The invisible hand theorem comes from
Objective: Analyze the effect of changes in supply and demand on the equilibrium price and quantity. 3. The law of demand states that the quantity demanded of a good is inversely related to the price of that good. Therefore, as the price of a good goes up, the quantity demanded goes up
up, the quantity demanded goes down
down, the quantity demanded goes down
down, the quantity demanded stays the same
4. Which of the following situations best demonstrates the law of demand?
Moviegoers react to an increase in the price of a ticket by seeing fewer movies per year.
Moviegoers see fewer movies per year due to an overall decrease in the quality of newly released motion pictures.

An increase in the number of people writing economics textbooks results in a decrease in average textbook prices.
Objective: Determine how elasticities affect pricing and purchasing decisions.
5. If quantity demanded does not change when the price changes, the demand
has unit elasticity
is perfectly inelastic

The law of diminishing marginal utility
The law of diminishing marginal productivity
The law of supply
The law of demand
8. Marginal product eventually
declines because some inputs are fixed
increases because some inputs are fixed
declines because some inputs are variable
increases because some inputs are variable
Objective: Analyze the relationship between productivity and the cost of production.
9. Suppose you operate a factory that produces gadgets. Your current output is 1,000 gadgets. If your fixed cost is $10,000 and your total cost is $50,000, then the
average total cost of production is $500
average variable cost of production is $40
average variable cost of production is $50
marginal cost of production is $40,000
10. The average variable cost curve is a mirror image of the
total product curve
marginal product curve
average product curve
marginal cost curve
Objective: Analyze the effect of changes in the supply of and demand for factors of production on the price of inputs.
11. Suppose wages and employment decrease. These changes were most likely caused by a(n)
decline in immigration
increase in emigration
increase in the working age population
decline in business activity in the economy
12. The incentive effect refers to how much a person will change his or her
hours worked in response to a change in the wage rate
wage rate in response to a change in productivity
quantity demanded of a taxed good in response to a change in the tax rate
wage rate in response to a change in the tax rate on earnings
Objective: Analyze the effect of changes in marginal revenues and costs on a firm’s profit-making potential.
13. Rachel left her job as a graphic artist, where she earned $42,000 per year, to open her own graphic arts firm. Her explicit costs for the new business include
only the expenses incurred for office space, equipment, and supplies
only her foregone salary of $42,000 per year
both the expenses incurred for office space, equipment, and supplies, and her foregone salary of $42,000 per year
neither the expenses incurred for office space, equipment, and supplies, nor her foregone salary of $42,000 per year
14. If your company cell phone bill is either $40 when you use up to 300 minutes per month or $80 when you use between 300 to 400 minutes per month, the marginal cost of the 301st minute is
Week Three: Market Structure
Objective: Compare various market structures and their characteristics.
15. A market structure in which one firm makes up the entire market is
16. There are many restaurants in Raleigh, North Carolina, each one offering food and services that differ from those of its competitors. There is also the free entry of sellers into the market, and each seller serves a small fraction of the total number of meals served each day. The restaurant industry in Raleigh is best categorized as
a pure monopoly
Objective: Evaluate the effectiveness of competitive strategies within market
17. The difference between a monopolist and a monopolistic competitor is that
a monopolist equates marginal revenue and marginal cost while a monopolistic competitor equates price and marginal cost
the average total cost curve of a monopolistic competitor is tangent to the demand curve in long-run equilibrium, but the average total cost curve of a monopolist can be in a position below the price in long-run equilibrium;
the average total cost curve of a monopolist is tangent to the demand curve in long-run equilibrium, but the average total cost curve of a monopolistic competitor can be in a position below the price in long-run equilibrium;
the average total cost curve of a monopolist is tangent to the demand curve in long-run equilibrium, but the average total cost curve of a monopolistic competitor can be in a position above the price in long-run equilibrium
18. If a perfectly competitive firm finds that price is less than the average variable cost, it should
not adjust output if marginal cost equals price
shut down immediately
increase output until price equals marginal cost
decrease output until price equals marginal cost
Objective: Determine profit-maximizing strategies based on market structure analysis.
19. A perfectly competitive firm facing a price of $10 decides to produce 100 widgets. If its marginal cost of producing the last widget is $12 and it seeks to maximize profit, the firm should
produce more widgets
produce fewer widgets
continue producing 100 widgets
20. If a firm has a monopoly over the sale of photographic paper and seeks to maximize profits, it
adjusts the price of the product until demand becomes perfectly inelastic
will set the price of the product equal to the marginal cost of production
will set the price of the product equal to the average total cost of production
will set the price of the product so its marginal revenue equals its marginal cost
Week Four: Public Policy in Economics
Objective: Analyze the effect of externalities on market outcomes.
21. The best example of a positive externality is
roller coaster rides
22. The cost of running an electrical utility includes costs for fuel, labor, and capital. In addition, there are sometimes costs associated with pollution from the utility, such as increased health care costs for people living near the utility. To an economist, the costs associated with the pollution resulting from additional electricity are
marginal private costs
marginal social costs
the difference between marginal social costs and marginal private costs
the sum of marginal social costs and marginal private costs

Objective: Analyze the effect of government interventions, taxation, and regulations on economic behavior.
25. When government imposes a per unit tax on a product, the net price producers receive for the product after all taxes typically
increases by the amount of the per unit tax
increases by less than the amount of the per unit tax
decreases by the amount of the per unit tax
decreases by less than the amount of the per unit tax
26. In 1997, the federal government reinstated a 10% excise tax on airline tickets. The industry tried to pass on the full 10% ticket tax to consumers, but was only able to boost the price per plane ticket by 4%. From this, you can conclude that the
