Course Description: This is a “core” social science course for the University of Nevada, introducing the
student to economic theory and its application to individual, business, and governmental decision-making.
Upon successfully completing this course, the student will possess a basic understanding of introductory
microeconomic and macroeconomic concepts. More precisely, the student will
(1) understand factors influencing consumer and producer decisions;
(2) understand how a market works to determine the price of a product and the quantity bought and sold;
(3) understand economy works as a whole;
(4) possess an elementary knowledge of US macroeconomic history;
(5) understand how government may be able to influence an economy through policy changes and why
government may not be able to effectively influence the economy;
(6) possess some elementary theoretical and empirical tools used to perform economic analysis;
(7) develop oral and written communication skills.
Required Course Materials:
(1) Freakonomics, Steven D Levitt & Stephen J. Dubner, 2005.
(2) The Economic Naturalist, Robert H. Frank, 2007.

EconWiki Contributions: One effective way to learn a subject is to write about it. To write effectively
about a subject, you must understand it. Also, writing helps you learn to think more effectively. Good
writing is good thinking. A significant portion of your grade will be to work with at least one other
person, but no more than two on a chapter that explains some broad idea or principle within economics.
Another portion will be associated with writing up definitions of key terms and phrases and writing up
associated applications. You also will obtain credit by reading the work of others, and editing it when you
believe you can improve it.
1
Assignments: You will be given short assignments every now and then. Each assignment will focus on
learning a particular skill or set of skills.
Participation: People learn more when they are more engaged. To be useful, economic thinking must
become a part of your thinking. This typically requires practice, and this is why a significant portion of
your grade will be allocated to participation.
You will have opportunities to earn participation credit in
the following ways:
1. In Class Discussion: At the beginning of most classes, current events will be discussed. You are
expected to keep up on current events by reading (as opposed to just watching TV or listening to the
radio). One convenient way to do this is by picking up a free copy of the New York Times that is
available all over campus. There are also many good internet sites you can use. Pay special attention
to the editorials of columnists who comment on news events and offer policy opinions. Over the
semester, you may be surprised to learn how much insight you can gain by thinking about current
events from an economic perspective
2. Asking Questions: You will have reading assigned that will help learn economic ideas. If some
element of this assigned reading particularly caught your interest, you should express your interest
about a topic in class. Perhaps more importantly, you should ask questions about anything in your
reading that is not clear to you. Learning to ask good questions is part of becoming a more mature
scholar.
3. Web Campus Discussion: You may use Web Campus to ask questions when you think others in the
class may benefit from hearing an answer. You may also comment on a current event, or on your
reading, or on the post of another student. In general, you will earn more participation credit for more
posts, but your posts should be good posts, not fluff.

4. Market and Command Failures
Key concepts: Externalities, Public Good, Private Good, Common Resource, Tragedy of the Commons

Command Failures
o Incentive compatibility
o Unintended consequences
o Quality improvement

Market Failures
o Externalities (Benefits received without costs paid, or costs incurred without benefits received.)
 External Benefits: Lead to under production
 Consumption Externality: Social demand higher than market demand
o Education: Others may benefit from the education you pay for
 Production Externality: Social supply higher than market supply
o Bee producer: Orchard owner benefits, but does not pay
o Orchard owner: Bee producer benefits, but does not pay
 External costs: Lead to over production
 Consumption Externality: Social demand lower than market demand
o Automobile consumption: Pollute the air, generating health costs to those
who walk
o Offensive behavior or speech: In consuming your freedom, you injure
others
 Production Externality: Social supply lower than market supply
o Coal burning power plants: Pollute air, CO2 emissions
o Solar panels: Produce electricity but are ugly
 Policy Solutions
 Direct regulation: Laws to mandate activities generating positive externalities and
restrict activities generating negative externalities
 Market solutions
o Pigouvian tax or subsidy: Per unit tax is equal to estimate per unit
external cost, and per unit subsidy is equal to estimated per unit external
benefit.
 Internalizes social cost or social benefit
 Lets market determine amount of activity, not government
o Permits to pollute (permit to emit negative externality)
 For negative externality
 Issue fixed number of permits
 Those who cannot much reduce the externality emission will be
more willing to buy the permits
 Those who can reduce their externality emission have an incentive
to do so because they can make money by reducing their
emissions and selling their permits
 Sunset clause, retiring a fraction of the permits over time, can
reduce the externality, while still allowing the activity
4
o
Public Goods
 Four types of goods
 Rival, exclusive: Private goods (e.g., ice cream, car)
o Private property rights (use, exclude use of others, transfer ownership)
 Non-rival, non-exclusive: Public goods (e.g., national defense, air, broadcast TV)
 Rival, non-exclusive: Common resource (e.g., fish in the ocean, living room)
 Non-rival, exclusive: Club goods (e.g. cable TV, journal subscriptions, roads)
 Pure public Good
 Non-rival
o Natural monopoly
 Strong incentive for entry if monopoly is profitable
 Risky to produce
 Marginal cost is zero, but cannot charge zero and be in business
 Non-exclusive
o Free rider problem (Why should I pay when someone else will?)
o Tragedy of the commons (Why should I not use the resource when
someone else will?)
 Problems with paying to produce non-private goods (underproduction)
 Solutions to public good problems

12. Perfect Competition
Key concepts: Market power, price, marginal revenue, entry and exit, economies of scale
 Defining perfect competition
o Firms have no market power
 Demand curve facing firm is horizontal, firm cannot influence market price
 Marginal revenue equals price
o Firms maximize profit
 Chooses output level where marginal revenue=marginal cost
 Since price=marginal revenue, price=marginal cost must also hold
o Free entry and exit
 Profits encourage entry
 Losses encourage exit
7



 Zero profit condition: price=average cost
Plotting perfect competition diagrammatically
o Price > average cost: Economic profit encourages entry and decreases price
o Price < average cost: Economic loss encourages exit and decreases price
o Price=marginal cost and price=average cost only where average cost is at a minimum
Examining the efficiency of perfect competition
o Allocative efficiency: price=marginal cost
o Productive efficiency: price=minimum average cost
o Perfect competition is productively and allocatively efficient
Using the perfect competition model
o If higher fixed costs decrease minimum average cost, then the average firm size will tend
to grow and consumers will benefit by paying lower prices.
o If resource depletion increases minimum average cost, then prices will increase over
time
13. Imperfect Competition: Monopoly and Monopolistic Competition
Key concepts: Market power, contestable market
 Defining monopoly
o There is a single firms, which has market power
 Demand curve facing firm has negative slope because firm influences market
price
 Firm can sell more if price is lower, but will sell less if price is higher
 Marginal revenue less than price
o Firms maximize profit
 Chooses output level where marginal revenue=marginal cost
 Since price>marginal revenue, price>marginal cost must also hold
o No free entry, but free exit
 Barriers to entry protect economic profits
 Losses encourage exit, which means the product will not be provided to anyone
 Defining monopolistic competition
o Competition eliminates economic profits
o Zero profit condition: price=average cost
 Defining a contestable market
o Competition from a potential entrant economic profits
o Zero profit condition: price=average cost
 Plotting monopoly diagrammatically
o Price  average cost: The monopolist must avoid economic loss to remain in business
o Marginal revenue=marginal cost
 Plotting monopolistic competition or a contestable monopoly market diagrammatically
o Price > average cost: Economic profit encourages entry and decreases price
o Price < average cost: Economic loss encourages exit and decreases price
o So, Price=average cost us hold
 Examining the efficiency of imperfect competition
o Allocative inefficiency, since price>marginal cost
o Productive inefficiency, since price>minimum average cost
o Imperfect competition is productively and allocatively inefficient
 Keys to Efficiency
o No market power: So, an increase in price will drive customers to a competitor
o Free Entry: To eliminate economic profit and reduce price to average cost
 Using the imperfect competition model
o Generic Drugs: The value to consumers of making close substitutes available.
