Syllabus Honors 220: Economic Theory and Policy OSN 203: MW 1:00-2:15 Professor Mark Pingle pingle@unr.edu; 784-6634 Office Hours (AB 319B) Monday and Wednesday; 2:30-3:45 and by appointment Fall 2011 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.

Grading: 20% Midterm 1: Monday, October 3 20% Midterm 2: Monday, November 14 25% Final: Monday, December 19, 10:15-12:15 20% EconWiki Contributions 10% Assignments 5% Participation 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.

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 o Government provision of the good: Roads, national defense o Government regulation of access: Fishing permits, broadcast licenses. o Cultural Values: “pay your fair share,” “leave some for someone else”, the “golden rule” 5. Modeling a Market Key concepts: market, shortage, surplus, supply, demand, equilibrium, market price, product markets, factor markets Key model: Supply and demand market model Outline Schematic of an economy’s market structure: Product markets vs factor markets Supply and demand model o Demand Measure of willingness to buy Factors influencing demand: Price, income, other prices, expectations Law of Demand Individual demand curve Market demand curve o Supply Measure of willingness to buy Factors influencing supply: Price, costs, expectations Law of Supply (not recognized as much as Law of Demand) Individual supply curve Market supply curve o Surplus, shortage, and equilibrium in the market The stability question: Is the equilibrium stable? Market price: How much will a product cost? Price increase: When will this occur? Price decrease: When will this occur? 6. Using a Market Model Key concepts: price ceiling, price floor, comparative static analysis Key model: Supply and demand market model 5 o The effects of price controls (Market in disequilibrium) o Price ceiling: Rent control example o Price floor: Agricultural price support example How markets work (Comparative static analysis: Market in equilibrium) o Market for health care Supply side shock: Increase in cost of providing health care Demand side shock: Increase in income Two shocks at once: Which do you think dominates? o Market for fish (Illustration of market period versus long run) Market period: Price reflects demand, not cost of production Long Run: Price reflects costs, not demand o International trade World price Determines what is imported and what is exported Free trade: Effects on domestic prices and consumption Import Restrictions Tariff Quota Dead weight welfare losses of tariffs and quotas 7. Consumer Decisions: Product demand and labor supply Key Concepts: Utility, marginal utility, law of demand, law of diminishing marginal utility, income effect, substitution effect, substitutes, complements, normal good, inferior good, elasticity, labor supply, product demand, Utility, marginal utility, and the law of diminishing marginal utility Budget constraint: Consumption tradeoffs Law of Demand: Substitution effect and income effect, role of law of diminishing marginal utility Deriving product demand curve: Result of consumption tradeoffs Types of goods: Normal versus inferior, substitute versus complement Deriving labor supply curve: Result of labor-leisure tradeoff 8.

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. 8 14.
