Econ 103 Final Exam
2. Accounting Profit and Economic Profit a. Very briefly explain the difference between accounting profit and economic profit. Your answer must be to the point and very specific.
Accounting Profit = Total Revenue - Explicit Costs Economic Profit = Total Revenue - Explicit Costs - Implicit Costs The difference is that accounting profit subtracts direct monetary outlays from the firm's revenue, while economic profit subtracts direct monetary outlays AND forgone opportunities from the firm's revenue. Economic profit considers forgone alternatives including everything that is given up such as money that used to be earned, but now is not because you are running your own business.
T/F If the quantity demanded of a good is unresponsive to a change in the price of that good, demand is elastic.
False
T/F In economics, the cost of something is exactly how much money you paid for it

Consider the market simulation activity that we did together in class. b. List the specific steps that describe the process through which the market moved to equilibrium as the activity moved from round one into rounds two and three. Hint: I am asking you to identify and state the forces at work that drove the outcome explained in part a. I clearly repeated these steps in class many times. You must list at least three steps to receive full credit. (3 points)
Buyers bring willingness-to-pay based on benefit/value from consumption. Sellers bring willingness-to-sell based on opportunity cost of production. Buyers and sellers interact and exchange seeking to gain (follow their self-interest). The market moves toward equilibrium guided by market forces (invisible hand) as buyers and sellers seek to gain through engaging in voluntary exchange (become better off). This process is the result of.... • INTERACTION • INFORMATION/EXPERIENCE/KNOWLEDGE • COMPETITION (ACTING ON INFO/EXP/KNOW) ...leading to an established narrowed price range with more trades and increased well-being. Markets increase the well-being of society through interaction and voluntary/mutually beneficial exchange.
1. Price Elasticity of Demand & Total Revenue (5 points) Consider the following newspaper quote: "Great weather conditions combined with a new harvesting method increased yields resulting in a bumper crop of oranges in Florida last year. This bumper crop drove down orange prices by 20% and as a result of the new lower price, orange sales to consumers increased by 5%. a. Given this information and assuming there were no other changes, what is the price elasticity of demand for oranges over this range? Hint: I need an exact number as an answer as well as a general interpretation or characterization of this number in terms of elasticity. (2 points)
Ed=%deltaQd/%deltaP = 5/-20 = -1/4 = -0.25 Inelastic (unresponsive, small) The negative sign illustrates the Law of Demand meaning that P and Q move in opposite directions
T/F According to the law of supply, an increase in the demand for corn will eventually result in an increase in the supply of corn as the price rises.
False
T/F Consider a tax placed in a market with a normal upward sloping supply curve and downward sloping demand curve. The lost well-being from the tax associated with units still purchased represents dead-weight-loss while the lost wellbeing from the tax associated with units no longer bought and sold represents tax revenue.
False
T/F Consider the example from class where society agreed to reduce pollution by 30%. From the perspective of all firms jointly, the most efficient plan would be to require all polluting firms to reduce emissions by the same % amount.
False
T/F Consider the example from class where society agreed to reduce pollution by 30%. From the perspective of all firms jointly, the most equitable (fair) plan would be to require all polluting firms to reduce emissions by the same % amount.
False
T/F Demographers predict that over the next several decades, the average age of Americans will rise significantly as the elderly make up a larger and larger share of the total population. In the US market for medical care (S&D), the likely impact of this statement would be that the demand for medical care would increase which would in turn increase the supply of medical care.
False
T/F If the US has a comparative advantage in the production of a product, they must also have an absolute advantage in the production of that product.
False
T/F If the US market in isolation has a higher price compared to the world price with trade, then the US is said to have a comparative advantage in the production of this product.
False
T/F Positive economic analysis uses the information provided from normative economics to prescribe policy actions designed to improve a particular situation.
False
T/F Suppose a city is considering a policy to reduce congestion in the downtown area. They decide that lowering the bus fare (price) would make the bus more attractive and lead to fewer cars and less congestion. The city hires an economist to research this issue and she reports that the estimated price elasticity of demand for bus rides is -0.1. Given your answers to questions 16-21 there is likely nothing that the city can do in terms of alternative policies to successfully reduce congestion.

False
Consider the market simulation activity that we did together in class. a. What two specific features were clearly seen in the data as the activity moved from round one into rounds two and three? Hint: Your answer should be complete and very specific. (3 points)
In round one there were very few transactions and there was no single price, but rather the prices trades took place at were dispersed or spread out over a wide range. In rounds two and three, the prices of the transactions taking place became concentrated within a narrow range approximately between $4.20 and $4.40 and the number of transactions taking place increased significantly. • ESTABLISHED PRICE (NARROW/CONCENTRATED RANGE) • MORE TRADES The squeezing of the price into a narrow range facilitated the trades that make both buyers and sellers better off resulting in an increased level of well-being among market participants (buyers and sellers) as more and more trades happened at an established price. The market moved to EQUILIBRIUM! Voluntary transactions create well-being!
4. Monopoly: Good or Bad Are monopolies good or bad? Very briefly comment on this question given your reading in the textbook and our class discussions.
The US has anti-trust laws to prevent monopoly power basically because of the inefficiency created as the monopolist restricts output and marks the price up above the marginal cost of the last unit produced (DWL). Generally speaking these laws help consumers by lowering prices and increasing consumer surplus. We do allow natural monopolies with regulation where the best example is electricity. We also allow monopoly power through the government granting the right to one firm to be the only seller through license agreements and patents/copyrights. One example of this is the cable TV market where a municipality sells the monopoly rights to one company for a fee thereby generating government revenue for the municipality. So in reality when you buy cable TV, you are really also helping to fund police and fire departments etc. Another example is with prescription drugs where firms are granted patent rights to be the only seller for some period of time. The result is high priced prescription drugs as new drugs are patented, but eventually we see competition and falling prices as generics are introduced when the patent runs out. The argument in favor of this is that we can have new beneficial drugs at high prices through research and development of firms because they have the incentive of profit, or instead we can fewer new beneficial drugs because of the lack of profit incentive leading to less research and development. There are others who argue that this patent protection is abused by drug companies as they fight for patent extensions and also as they introduce new drugs that are slightly different, but that do essentially the same thing and get patents and market them effectively to reap high profits and fight off competition from generics. These people believe that the drug industry is in need of more regulation including price controls. It is also possible that the government could direct and finance all pharmaceutical R&D, thus providing lower priced new beneficial drugs, but with higher taxes.
Consider the following newspaper quote: "Great weather conditions combined with a new harvesting method increased yields resulting in a bumper crop of oranges in Florida last year. This bumper crop drove down orange prices by 20% and as a result of the new lower price, orange sales to consumers increased by 5%. b. Strictly in terms of total revenue generated by sales, was this bumper crop of oranges good news or bad news for orange growers on average? Briefly explain your answer. Hint: Your answer should be very specific. Be sure to use some economic language and the economic way of thinking and refer to your answer to part a. (3 points)
The above shock would be illustrated by a rightward shift of the supply curve causing an excess supply of oranges at the initial price. In order to restore equilibrium the price will adjust and buyers will respond according to the Law of D. P ↓ Qd ↑ But by how much? When P ↓ and Q ↑, total revenue (P*Q) can increase, decrease, or remain unchanged depending on the price elasticity of demand over the relevant range. According to part a from above, for every 1% ↓ P, there will be a corresponding 0.25% ↑ Qd. In this example the demand is inelastic meaning that the action was on the lower portion of the demand curve. Thus, the quantity response (↑ Q) was small relative to the price change (↓ P). Therefore, total revenue (P*Q) will fall which on average could be bad news for orange growers. That is, the increase in sales did not make up for the decrease in price.
Why is the distinction you gave in your answer to part a important to economists? That is, what question are economists trying to answer when they calculate profit as compared to the question accountants are trying to answer when they calculate profit?
The difference described above is the result of the different questions that accountants and economists are trying to answer when they calculate a firm's profit. The accountant is asking how much is left over after all monetary expenses are netted out thereby revealing the income to the entrepreneur from running the business. The economist is asking how well the entrepreneur is doing running the business compared to her next best alternative, and therefore the economist must consider all forgone opportunities as costs.
What are the necessary conditions for a firm with some degree of monopoly/market power to be able to price discriminate? Very briefly explain
The monopolist must have some price setting power and they must have information regarding the willingness to Pay (WTP) for their product across individual consumers or groups of consumers. The monopolist must also be able to segment the market (separate buyers according to their WTP) and be able to prevent re-sale of their product from those who buy at a low price to people willing to pay more. That is, they must be able to keep selling to their high WTP customers at the high price while also selling to the low WTP customers at the lower price.
T/F A per unit tax (on either buyers or sellers) in a market with a normal upward sloping supply curve and downward sloping demand curve will create a wedge between the price paid by consumers and the price received by sellers and the amount of this wedge will be equal to the amount of the tax regardless of the price elasticities of demand and supply

T/F Based on economic theory, if Germany specializes in producing the good they have a comparative advantage in and engages in trade, their consumption possibilities will increase beyond their initial production possibilities.
True
T/F If the market for a product generates a negative externality (production or consumption) that has not been internalized, the private market outcome will result in a quantity bought and sold that is more than the optimal quantity.
True
T/F If there is an excess supply of a good in a market, then the price will tend to fall as a result of market forces
True
T/F If total revenue is $100, explicit costs are $50, and implicit costs are $30, then accounting profit equals $50.
True

T/F Suppose a city is considering a policy to reduce congestion in the downtown area. They decide that lowering the bus fare (price) would make the bus more attractive and lead to fewer cars and less congestion. The city hires an economist to research this issue and she reports that the estimated price elasticity of demand for bus rides is -0.1. A policy interpretation of the price elasticity of demand for bus rides of -0.1 suggests that this policy will not be successful in reducing congestion.

True
c. Very briefly explain the concept of zero economic profit in a perfectly competitive industry setting. Keep your answer simple and to the point.
Zero economic profit means that the firm is earning a normal rate of return on their investment. This is just another way of saying that the revenue from selling output is exactly equal the total opportunity cost incurred by the firm during the production process. In a perfectly competitive industry setting the long run equilibrium will tend toward zero economic profit for all firms as competition drives price down to approaching the opportunity cost of production. We expect there will be entry if the typical firm is earning economic profit in the short run which will drive the price down and eliminate the profit through competition. Similarly, we expect there will be exit if the typical firm is earning economic losses in the short run which will increase the price and eliminate the losses. We saw an example of this in class during the candy market structure simulation activity where prices were driven down to the opportunity cost of production in the market with many competitors. The firms in the competitive market setting with many sellers of an identical product had no market power and therefore were price takers destined to earn zero economic profit. Competitive firms are limited in the price they can charge by both the demand for their product as well as the competition from other firms selling an identical product.
3. Competition and Monopoly a. List three characteristics of a perfectly competitive industry setting b. Given your answer to part a, what is the very general reason that a monopoly industry setting occurs? c. Given your answers to parts a and b, very briefly describe the key difference in outcomes between monopoly markets and competitive markets?
a. -- Many sellers -- Identical product across all sellers -- Free entry and exit -- Perfect Information and resource mobility b. In a monopoly industry there is one seller of a unique product such that the seller faces no direct competition. This result arises when there is/are significant barriers to entry resulting in a lack of competition. c. The lack of competition results in market power for the monopoly firm which allows them to be a price maker and as such they are able to earn economic profit. We saw an example of this in class during the candy market structure simulation activity where the monopolist was able to charge $0.25 because the only limit on the price they could charge was what consumers were willing to pay given by the demand for their product. In the long run this price making ability (market power) will result in economic profit for the monopolist due to a lack of competition resulting from some barrier to entry as long as consumers are willing to pay for the product.

a. Canada has an absolute advantage in the production of coal.
1. Joe runs a small boat factory. He can make ten boats per year and sell them for $25,000 each. It costs Joe $150,000 for the raw materials (fiberglass, wood, paint, and so on) to build the ten boats. Joe has invested $400,000 in the factory and equipment needed to produce the boats which are now assets that he owns: $200,000 from his own savings and $200,000 borrowed at 10 percent interest (assume that Joe could have loaned his money out at 10 percent, too). Joe can work at a competing boat factory for $70,000 per year. Hint: The funds invested in the factory and equipment ($400,000) are not treated as a cost here because they represent assets of the firm, there is however a cost associated with obtaining these funds. a. What is the total revenue Joe can earn in a year? b.What are the explicit costs Joe incurs while producing ten boats? c. What are the total opportunity costs of producing ten boats (explicit and implicit)? d. How much is Joe's accounting profit? e. How much is Joe's economic profit? f. Is it truly profitable for Joe to operate his boat factory? Very briefly explain.
a. TR = P * Q = (25,000 * 10) = $250,000 b. The explicit costs are the costs that Joe incurs for which he makes a monetary outlay (takes money out of his pocket). The $400,000 itself is not an explicit cost because Joe owns the factory and equipment and it is therefore an asset. Explicit costs = 150,000 + 20,000 = $170,000 raw materials plus interest on the loan (money borrowed) c. Total opportunity costs = explicit costs + implicit costs = 170,000 + (70,000 + 20,000) = $260,000 The implicit costs are the forgone wage and the lost interest on savings d. Accounting profit = TR - explicit costs = 250,000 - 170,000 = $80,000 e. Economic Profit = TR - total opportunity cost = 250,000 - 260,000 = - $10,000 f. In order to answer this question we look at the two options available to Joe. 1: Joe can operate the boat factory and make an accounting profit of $80,000. 2: Joe can work for the competition and make $70,000 and also earn 10% interest on his savings, a total of $90,000. Comparing the two options, Joe would be better off not operating the boat factory. In economic terms, it would cost Joe $10,000 to operate the boat factory, which is the amount of his economic Profit of -$10,000 found in part e. Because Joe would be better off working for the competition it is not profitable for Joe to operate a boat factory
