The student will be able to develop a systematic method for analyzing economic problems. 4. The student will be able to apply definitions of economic efficiency, equity, and liberty. MICROECONOMICS - The branch of economics that examines the functioning of individual industries and behavior of individuals decision-making units, that is, business firms and households. Pg 7 ECONOMICS is the study of how individuals and societies choose to use the scarce resources that nature and previous generations have provided. (Pg 2) Economics studies decision making regarding the allocation of scarce resources in individual households and firms to satisfy human wants. 1. [Who uses resources to produce goods and services.?] Resources are goods and services that are used to produce other goods and services. Resources are: Natural, labor, capital, entrepreneurship. All these resources are used to produce goods and services within a specific time frame. Time may be the ultimate constraint faced by individuals and economies. All economies have these resources but not necessarily in the same quantities. The resources are scarce because human wants are unlimited. The goods and services people want far exceed any nations productive capacity to produce them. Four characteristics used to describe entrepreneurs A. Entrepreneurs view change(globalization) not as a obstacle but as a opportunity. B. Entrepreneurs exploit innovation to create opportunity. C. Entrepreneurs build and grow companies to bring their innovation to market. D. Entrepreneurs take significant calculated, personal risks in building their companies.

IDENTIFY PROBLEMS NORMATIVE VERSUS POSITIVE ECONOMIC PROBLEMS - Page 9 WHAT SHOULD BE? WHAT IS? Positive economics - An approach to economics that seeks to understand behavior and the operation of systems without making judgements. It describes what exists and how it works. Pg 8 Normative economics - An Approach to economics that analyzes outcomes of economic behavior, evaluates them as good or bad, and may prescribe preferred courses of action - Pg 8 An example of a positive economic question is, "What is the unemployment rate?" A normative economic question is, "Should the government attempt to lower the unemployment rate? Answers to positive and normative economic questions are based on a set of assumptions. Positive economic questions ask facts about a current market or our economy. Examples of positive economic questions are: What is the current wage for unskilled labor? , What was the wage of unskilled labor five years ago? , What is the industrial safety level?, What quantity of cocaine is being consumed in the U.S.?, What percent of people are using seat belts?, How many abortions occur in the U.S.?, What is our budget deficit?, How many imported goods do we consume?, How many doctors are licensed each year in our state? What is the inflation rate?, What quantity of money exists in the U.S.?, What is the current level of crime? 4.

The main 6 issue should always be stated as a question. Determine if you are analyzing a private or public policy issue. A public policy issue is one that requires action by government (either local, state or federal). A private policy analysis is one that requires individuals, households, or firms to take action. 3 pts Step 2 Determine the primary area of concern relating to this issue. If this is a current policy or program, discuss the motivating factor(s) that caused this policy or program to be adopted. If this is a new policy or program to be adopted, discuss the main concerns behind this new policy or program. 9 pts Step 3 Discuss potential consequences of answering this question on efficiency, equity or on other identifiable aspects of individual and social well-being. Thoroughly discuss the assumptions behind any changes in efficiency, equity, and liberty that may occur. Indicate which part of product market efficiency is affected. (Allocative, technical efficiency or both) If you have selected a public policy issue start with the following definitions of efficiency, equity, and liberty: Product market efficiency: 1. Right goods and services are produced in the right quantities. 831/10 U.S. Wants Report Card for Cars WSJ B1 A 2. The least value of resources are used in producing a good or service. Or the maximum amount of goods and services are produced with the existing resources. T 12. [How does the textbook define efficient markets? Pg 14] 13. [Is the definition above consistent with the textbook definition?] Equity - Fair access to goods and services 7 Goods and services are distributed in accordance with society=s wishes. In the U.S. we believe fair access to goods and services implies: 1. People who contribute the most to society consume the most 2. People who want the good the most consume it. 3. For some goods and services but not all, people who make little to no contribution to society deserve access to these special goods and services. Society may decide certain groups should have more goods and services and others have less. 2/1/10 Heists Targeting Truckers on Rise WSJ A3 Equity 14. [List methods society uses to distribute goods and services based on criteria one, two and three above.] This implies, people who make little to no market contribution to society deserve some goods and services. The poor will be helped if goods or services are produced at the lowest possible price. Society may decide certain groups should have more goods and services and others have less. Market Liberty - The freedom to use your resources as you see fit as long as the use of those resources does not significantly affect others. 3 pts Step 4 Discuss which assumptions you have made in step 3 you believe to be most valid by placing a S(strong), W(weak), or D(difficult to assess) after each assumption. 15. [Define an assumption.] 1 pts Step 5 Assess the source or sources of this article. Discuss any bias you perceive in the author of the article. Discuss any preferences you may have on this issue. 5 pts Step 6 Based on which assumptions in step 4 you believe to be most valid, make a decision on the question you posed in step 1. Your grade will be determined on how consistent your decision is with steps 3 and 4, and how well you have considered alternative viewpoints. You should also consider if the concerns you listed are adequately addressed by the proposed solution in step #2. If you decide to reject this policy, state an alternative solution. If no good alternative can be 8 found, maybe a second best solution will have to do. 2 pts Step 7 Identify pivotal assumptions that would cause you to reverse your conclusion in step #6. The seven-step procedure is demonstrated below: Michael Vincents= parents suggest to him that he should study more hours in the week. STEP #1 Should you study more hours per week? Step #2 Students' grades are not high enough - allocative efficiency. 16. [Why is subject of high grades an allocative efficiency issue? Application] Step #3 Benefits of studying more hours per week would be to get better grades(allocative efficiency), and ultimately, perhaps, a better job (technical efficiency and equity) Benefit of Studying more hours per week Allocative efficiency increases time cost. Assumptions 1. Student values more study more than the opportunity 2. Grades improve Technical efficiency increases 3. Student is more productive Equity increases 4. Pay increases as a result of being more productive s 9 Potential Costs of studying more hours Allocative efficiency decreases 5. Student values more study time less than the opportunity cost. 6. Grades get worse Technical efficiency decreases 7. Student is less productive as a Result of studying more hours 8. Pay does not as a result of being more productive Webster=s dictionary defines assumption as Aanything taken for granted.@ If I suggest allocative efficiency increases if a student studies more, what factors are taken for granted? 17. [Ask the class two questions: How many people drove to campus today? How many people will drive off campus today? Which is a positive economic question? Which of these responses is based on assumptions? Application] Step #4 The student should place an S(strong), W(weak), or D(difficult to assess) after assumption 1-8. Parents and students may assess these assumptions differently. Now evaluate the assumptions behind each of the benefits and costs. If the student values the additional study time more than the alternative, than place a S (for strong assumption) by assumption #1. Opportunity cost may include many things such as: lost wages, lost friends (people who study more must decline more invitations), less of other leisure activities (T.V., hobbies)etc. If the student believes grades will actually increase as a result of more study, place an S by assumption 2. If the student believes they will become more productive as a result of additional study hours, than place a S by assumption 3. If the student believes that additional productivity will be rewarded in the job market, place an S by assumption 4. If assumptions 1-4 are rated as strong, 4-8 must be rated as weak. Both assumptions 1 and 4 can not be rated as strong, but the both could be rated as difficult. 10 Hint: When listing assumptions for step #3 look for the counter opposites and place them under costs. If you have assumptions listed under cost, check to see if the counter opposite is listed under benefits. Step #5 Did the person suggesting the increase in study hours present all sides of the issue? Is the person making the decision comprehending all sides of this issue? Step #6 Now make a decision regarding study hours. Step #7 Which of the six assumptions (1-8) are critical to your decision? That is, if your rating changed from strong to weak or from strong to difficult, your conclusion in step 6 could change. If a student decides to study more hours in a week, the potential benefit are higher grades, more personal satisfaction, and better pay. Higher grades is a potential benefit, because some assumptions have to be made. It is not certain that more study hours will increase grades and that higher grades will make the person better off. If a student decides to study more hours there are costs. The opportunity cost represents benefits from the activity or activities will be foregone as a result of increased study time. Even if the student devotes more time to studying, it is not certain his or her grades will increase. It is possible that, if the student studies more, and grades go up, as a result, the student is worse off nonetheless. For example, as a result of more study time, his girl friend leaves him. ECONOMIC THEORY - A STATEMENT OR SET OF RELATED STATEMENTS ABOUT CAUSE AND EFFECT, ACTION AND REACTION, IN ECONOMIC LIFE. - Pg 10 III. UNDERSTAND THE CONCEPT OF CETERIS PARIBUS - Pg 11 The bottom line in economic analysis is placed on three crucial issues listed below. - Pg 13-14 Economic Goals 1. Efficiency Micro Macro 11 Growth Stability Inflation - Hyperinflation 2. Equity Inflation 3. Market Liberty - The right to use our resources as we see fit as long as the use of those resources does not significantly affect others. The primary assumption most economists make when deciding on issues relating to efficiency, equity, and liberty is rationality. Rationality implies people act in there own best interests, even if these interest do not seem logical to us. It may not be rational for me to smoke, but it can be a rational decision for someone else. Economic efficiency has two components: 1) microeconomic efficiency and macroeconomic efficiency. The first principle of microeconomic efficiency is called technical efficiency. (T) The least value of resources are used in producing the good or service. Or the maximum amount of goods and services are produced with the existing resources. T The second principle of efficiency is called allocative efficiency. The correct amount of resources are being allocated to the production of this good or service. Pg 14 GRAPHS AND CHARTS Pg 18-23 OBJECTIVES: 1.

A crucial aspect of capitalism is the concept of private property. Individuals must be allowed to accumulate and trade private property. This explains laws against theft. 32. What is the incentive for allocative and technical efficiency under capitalism? Market systems decides the question of "To Whom" first. CONSUMER SOVEREIGNTY - The idea that consumers ultimately dictate what will be produced (or not produced) by choosing what to purchase – Pg 40 The general that directs all economic activity in a market economy is price. Price of Everything, Russell Roberts 17 Free enterprise – The freedom of individuals (market liberty) to start and operate private businesses in search of profits.

Command system (Socialism) is defined as a system of economic organization, characterized by the public ownership of the means of production and distribution. http://cafehayek.com/2010/08/worth-a-thousand-words.html Command is defined as a system of economic organization in which a central government either directly of indirectly sets output targets, incomes, and prices. Pg 39 In a command economy the questions of what? how? And to whom? are answered by a central authority. Socialism today has come to be associated with a welfare state. The state through a wide variety of transfer payments assumes responsibility for protecting its citizens. Private ownership of the means of production is permitted, with the state ownership of the means of production and distribution considered vital to society. 37. [Does command system emphasize the question of "What" , "How", or "To Whom"?] 12/26/09 Venezuela's President Threatens Toyota, GM WSJ A1 Assumption of a command system is government knows better.

Natural Resources------------- ECONOMIC RENT 2. LABOR ------------------------ WAGES 3. CAPITAL ---------------------- INTEREST 4. ENTREPRENEURSHIP ---- PROFITS Price of Everything, Russell Roberts 20 In pure socialism, land and capital are owned by the are no entrepreneurs since the therefore, the government and there government takes all the risks of production, income earned is totally related to wages.

The traditional economic system is one in which the questions of what? how? and to whom? are answered "traditionally." Typically, an elaborate system of customs, social mores, and accepted practices determine what goods and services get produced, lhow resources are combined to produce those goods and services, and whose wants get satisfied by consuming those goods and services. Although the Amish, the ante bellum South, and the Melanesian potlatch are frequently used examples of traditional economic systems, as with capitalism and socialism, no purely 22 traditional economic system exists. Nonetheless, many vestiges of tradition are to be found in the U.S. economy, influencing decisions of what? How? and To Whom? Examples include the large proportion of children who follow in their parents' career footsteps; use of queuing to ration available goods and services, stereotyping certain service workers; and division of household production tasks among household members, especially by gender. 5. Mixed Systems - Pg 40 Can Socialism Survive? 9/20/04 WSJ Capitalism consumers individual decisions to purchase goods and services decide the basic questions of what, and who producers decide the question of How. Socialism the government help decides the basic questions of what, how and who. Command the government decides the basic questions of what, how and who. Communism the people decide by a collective decision making process basic question of what, how and who are decided by some central authority. Mixed economy consumers decide the basic questions of what, some goods and government decides the questions of what, how and who for other goods. Most economies let the market, government, and tradition decide what, how, and who. The precise combination traditional forces how and who for the questions of of market forces, government forces, and determine whether the system is called capitalism, socialism, or traditional. 43.

Remember the old debate which came first the chicken or the egg? Some argue that teaching good business practices is the best way to improve a flawed system. I argue that good business practices are a function of the system and will only change when the system changes. Does ethics produce a good system or does the system produce good ethics? Should our society teach ethics in our schools and hope to produce a good society or should we have a system that requires good ethics and business practices. Which do you think will be most successful? Large numbers of buyers and sellers, easy entry and exit, homogeneous product, perfect information, and economic incentive mandate good ethics, i.e., good business practices. 62. [Which of the following businesses or industries do you believe would most likely be efficient and equitable: postal service, Wal-Mart, General Motors, General Mills, wheat 29 farming, and Dick's grocery?] 1. Perfect Competition implies the following assumptions: 1) large number of buyers and sellers, 2) homogeneous product, 3) easy entry and exit and 4) perfect knowledge on the part of producer and consumer, 5) economic incentive is present. Pg 144-145 Let's examine assumption number one. In baseball, the reserve clause tied baseball players to one team for life. There were not many buyers for a players services in fact, only one buyer. As a result, players bargained with only one owner. The owner also knew if the player refused the contract he was offered, his only opportunity was to quit baseball, since he could not bargain with another team. As a result, players became exploited (received salaries below what they were worth to the team). In baseball stadiums concessions are generally operated by one firm, and fans or other firms are forbidden to bring food or drink into the stadium. What happens to the price of a hot dog compared to street vendors? You guessed it, whamoo- $3.00 hot dogs. Now who is being exploited? When there are many buyers and sellers for labor and products, a fair trade is struck between producer and consumer. Have you ever noticed that management and employees are more responsive to consumer demands in Wal-Mart or K-Mart than in the U.S. Postal office? 2. Imperfect competition 1.

[List some markets that have large numbers of buyers and sellers?] Assumption number two - homogeneous product. This implies that all the producers are producing the same product. Did you ever ask yourself which farmer produced the last gallon of milk you bought? Of course not, it is not important since all milk is identical no matter which farmer produced it. Farmers are most efficient because they do not waste time and resources trying to differentiate their product. Farmers concentrate on lowering costs since product differentiation does not matter and price is out of their control. Assumption number three - Easy entry and exit into and out of the marketplace. In the 1950's, 60's and 70's G.M., Ford and Chrysler had very few rivals because of many barriers to entry such as capital costs (the cost of starting an automobile company is hundreds of millions of dollars or more), trade tariffs and quotas. What incentive did the big three auto producers have to produce a quality product? Quality at Ford, G.M. and Chrysler did not start to become job #1 until the tariffs and quotas started to disappear. Easy entry forces companies to be consumer conscious. If one firm does not deliver what the consumer wants, another will. In fact, large numbers may not be as important as easy entry in maintaining efficiency. If there is only one seller, but this seller is aware the market is easy to enter, prices are restrained. The threat of additional competition, if prices are raised too high, counterbalances few sellers. Most cable TV companies are given a monopoly in their market area (one seller). To counter balance this market power the cable companies are regulated as to price. 3/28/03 AWisconsin lags in disciplining doctors, national report says@ Wis. State Journal Repeat offenders from Web. Market power is the ability to raise without quantity demanded falling to zero.

Easy exit is as important as easy entry. If a firm is not delivering the best product at the lowest price and is faced with many sellers, the firm dies. But death of firms, unlike people, is not final because these resources (labor, capital, land, entrepreneurial ability and time) can be used elsewhere, dictated by consumer demands. Socialism is the perfect example where business was not allowed to fail, as a result, goods were few and of poor quality. An economist once said there is no such thing as a free lunch. The freedom to fail produces economic efficiency but it has its costs. People suffer the hardship of unemployment, and as a result of unemployment, divorce, theft and suicides occur. 70. [How does the government attempt to minimize this cost?] Assumption number four - Perfect Information about products and production methods. No market will ever have perfect information, but the importance of this assumption is that more information is better than less. The better informed people are the better choices people make in the market place, and as a result, markets function more efficiently. Markets most often fail because information about the product is lacking. As an example, someone advertises an imitation diamond ring for $24.95. The seller is aware of the quality of the imitation but the buyer is not. The purchaser receives the ring and is disappointed. An inefficient trade has resulted in making the seller better off but the buyer worse off as a result of insufficient information. 10/24/09 Learning to Love Insider Trading WSJ W1 7/31/10 Sites Feed Personal Details To New Tracking Industry WSJ A1 Benefits and costs of the internet http://www.newsweek.com/photo/2010/12/08/things-that-killed-the-in ternet.html 1"Judge Opens Information Services to Bells", Wall Street Journal, July 26, 1991 32 People spend thousands, and sometimes millions, of dollars to acquire more information.

How does this decision to rent the car relate to imperfect competition? Analysis] Assume the same individual knows someone in the city that is selling a car similar to the one he was going to rent. He also is aware of another potential buyer. Dr. Ronald Coase won a Nobel Prize in economics by showing how markets are affected by transaction costs. Parts of the transaction cost of buying and selling a car is the cost of acquiring information of what cars are available, the quality of the cars, and potential buyers for those cars. 74. Would you now rent or buy the car? Evaluation] Some people lease cars (rent) instead of purchasing them because 33 the lease payments are less than the purchase payments.

Re-examine questions 32 in chapter 2. Countries that have economic systems further from the competitive model have more corruption. The economic freedom index, Ashows a strong correlation: more economic freedom, less corruption.@2 When economics conflicts with ethics, economics usually wins. Imperfect market structure often provides opportunities for economics to conflict with ethics. When profits and ethics conflict, usually profit wins. The NCAA, illegal drugs, and the stock market are a few examples of economics conflicting with ethics. The NCAA regulates college sports. Federal law prohibits the sale of certain drugs. The Securities and Exchange Commission regulates activity in the stock market. The 117 division I-A schools in 2002 generated $454 million of revenue, $219 million profit, on men=s basketball. CBS is paying the NCAA $6 billion over the next 11 years to broadcast the men=s basketball tournament; the money is shared among NCAA schools. AAmong other things it shows how colleges, in their zeal to field teams that win games and draw big money are tempted to look the other way when it comes to enforcing academic standards@3 The office of National Drug Control Policy estimates for the year 2000 Americans spent about $36 billion on cocaine, $10 billion on heroin, $5.4 billion on methamphetamine, $11 billion on marijuana, and $2.4 billion on other substances. A seven-step analysis of illegal drugs is given in chapter 8. Certainly here is a case where economic interest conflicts with social interest. Insider trading (trading on information not available to the general public) is illegal in the stock market. The SEC has the difficult task of trying to prohibit insider trading. When millions and possibly billions of dollars can be made with inside information, profits again conflict with ethics. 81. [How successful will teaching business ethics be in imperfect competition?

Synthesis] Below is a bus schedule with 5 arrival and departure times, for the Askil Bus Company. Before the customer knows which bus she wants to take, she must first decide on a departure time. Arrivals 9:05 a.m. 11:05 a.m. 1:05 p.m. 3:05 p.m. 5:05 p.m. Departures 10:00 a.m. Noon 2:00 p.m. 4:00 p.m. 6:00 p.m. This bus schedule represents all the possible arrival and departure times of the Askil Bus Company. When you think of a bus schedule, you think of a list of arrival and departure times. The demand schedule represents all the possible price and quantity combinations of a good and service that will be sold in a specific time period. If the bus company states all arrivals and departures will be delayed by I hour 47 the entire schedule changes. If a friend tells you she will be departing at two o=clock you now know when she will be arriving. When you think of a demand schedule you should also think of many different prices and quantities. Supply schedule - A table showing how much of a product firms will supply at different prices per unit in the short run, ceteris paribus. Pg 80 The variables that motivate producers are: 1. Price of the product 2. Cost of production per unit 3. Profitability of related products pg 62 Quantity supplied - The amount of a product that a household would buy in a given period if it could buy all it wanted at the current market price ceteris paribus. Pg 62 Quantity demanded changes when product price changes and all other factors are held constant. Factors 2 and 3 determine the level of supply.

Candies. The assumption here is that each level of production at the various prices represents the profit maximizing level. This schedule can be shown graphically in figure below. All the assumptions of perfect competition apply. Intuitively the price must rise for the entrepreneur to produce a larger quantity because the costs of production must rise.

Candies to change the desired level of production (shift supply) at each price: cost of production, technology, taxes, subsidies, and profit expectations of alternative production. The supply schedule is upward sloping (larger quantity supplied if prices increases) because cost increases as quantity produced increases. 107. [How do you think the supply schedule for A.M. candies would look if the price of chocolate went up?] The new supply schedule #2 is shown below in figure 4.11.

Assume the cost of setting up this assembly line is negligible. How will the above supply curve be affected? Any improvement in technology will act like a decrease in costs and increase quantities offered at each price (shift the supply curve to the right). This is shown in table 4.12 below.

[Which of the above assumptions do you believe are most valid?] Assumption #3 You must assume strict enforcement of this law. Government realizes that a price floor with no exceptions would discourage firms from bringing to the market hard to reach oil. Oil that is very deep, must be extracted from shale or other rock, or oil from under the sea would not be brought to the market place. Therefore the government establishes two price floors one for old easy access oil and the other for new hard to reach oil. 124. [What is the incentive for oil companies under this two tiered pricing system?] When oil is stored it is very difficult to determine if this oil came from old wells or new wells. Assumption #4 Given a normal downward sloping demand and upward sloping supply curve a lower price of oil should have market incentive effects for producers and consumers. Consumers should react by being less energy conscious and producers should be less willing to bring oil to the market place (quantity demanded increases and quantity supplied decreases). Price answers questions of What, How, Who, and as a result affects efficiency and equity. If the government uses price to answer the "who" question, it simultaneously affects the "what" and "How question.
