You are an intern to the editor of a small-town newspaper in Mallsburg, Pennsylvania. Your boss, the editor, asks you to write the first draft of an editorial for this week's paper. Your assignment is to describe the costs and the benefits of building a new bridge across the railroad tracks in the center of town. Currently, most people who live in this town must drive 2 miles through thickly congested traffic to the existing bridge to get to the main shopping and employment center.

What are the benefits that citizens will likely receive if the bridge is built?
A. Any economic inefficiencies associated with the new income tax. B. Revenue lost by shopkeepers near the old bridge. C. Construction costs such as noise, additional (temporary) traffic, and other delays. D. The value of goods and services that the city could have purchased with the tax revenue had it not built the bridge. E. All of the above. <--------- A. Reduced travel time for commuters and shoppers. B. The value of the goods and services that citizens could have purchased with the additional tax burden. C. Less pollution from idling traffic. D. Issues of income distribution. E.

According to the Bureau of Labor Statistics, the average weekly earnings of production and non supervisory employees in education and health services was $822 in March 2015, up from $671 in March 2006. All else equal, such an increase in wages would be expected to reduce the quantity of labor demanded and employment should fall. Instead, the quantity demanded for labor has increased dramatically with more than 3.7 million jobs being created between 2006 and 2015. How can you explain this seeming discrepancy?
An increase in labor productivity increased labor demand and wages in education and health services
Related to Economics in Practice: Ethanol and Land Prices...The Economics in Practice in this chapter describes the adjustment of the corn and wheat market in the United States to federal mandate requiring refiners to use corn-based ethanol in the production of fuel. Up until January 2012, refiners were given a subsidy of $0.45 for every gallon of ethanol they blended into their fuel. This subsidy drove up the prices of other agricultural products such as wheat and substantially raised the value of farmland. Assuming the subsidy was still in place, what would happen to the prices of these other agricultural goods and to the value of farmland if oil prices were to rise extensively at the same time? Trace these changes in the economy using supply and demand curves. Assume a given ethanol production subsidy. Show how the market for corn would be affected (given the ethanol production subsidy) if oil prices were to rise.
At the same time, if oil prices rise, then the demand for land will INCREASE, INCREASING land prices. Further, if oil prices rise, then the wheat SUPPLY curve will shift to the LEFT. This will INCREASE wheat prices.

Remy is a New Orleans native who has lived for the past 7 years in Boston. For each of the last 7 years, he has made trips back to New Orleans for Mardi Gras, Jazz Fest, and Halloween. During 2015, the price of a round-trip ticket from Boston to New Orleans decreased from $575 to $350. As a result, Remy decided to buy new Mardi Gras and Halloween costumes that year and also decided to purchase tickets to see Harry Connick, Jr. perform at the TD Garden Arena in Boston. Explain how Remy's demand for Halloween costumes and concert tickets will be affected by a decrease in air travel prices. Explain why both income and substitution effects might be expected to increase Remy's number of trips to New Orleans.
His demand for these items will rise because less of his income will be used for plane tickets. Cheaper air travel increases real income and lowers the opportunity cost of trips to New Orleans.
Explain how imperfect information problems such as adverse selection and moral hazard might affect the following markets. The market for wireless Internet connectivity at large international airports. The market for renter's insurance. The market for used automobile tires. The market for pharmaceuticals purchased over the Internet.
It is difficult to know how well a company's Wi-Fi will work until after it is set up due to imperfect information. Those with insurance are less likely to take precautions to safeguard their property due to moral hazard. Sellers have more information than consumers, resulting in a disproportionate number of low-quality tires being sold due to adverse selection. Consumers cannot verify which companies selling pharmaceuticals are reliable due to imperfect information.

In the area around a local university, a number of food vendors gather each lunchtime to sell food to university students who are tired of dorm food. The university and the town have no license fees that apply to food vendors, preferring to let the market dictate how many and which vendors show up. Many different cuisines are represented on the street corner, including a cart sponsored by Madame Defarge selling gumbo and jambalaya. Madame Defarge sells a plate of either gumbo or jambalaya for $6. The food is made in the morning at her nearby restaurant, when the kitchen is otherwise unoccupied. Her crew of three, each of whom earns $14 per hour, takes 2.5 hours to make the 100 meals required by Madame Defarge. In creating these meals, they use ingredients equal to $100. Madame Defarge hires another worker to load her cart with food and sell it during the lunch hours. That worker costs $10 per hour and typically sells out the entire cart of 100 meals in 2 hours. The cart is rented for $90 per 5-day week. (The carts are not in operation on the weekends, when Madame Defarge is too busy at her restaurant.) What factors make this a monopolistically competitive market? What would you expect to see happen in this business?
Madame Defarge is one of many vendors. There are many types of food from which students can choose. There are no licensing fees for food-cart vendors. Madame Defarge's profit per meal is equal to $3.57 Firms would enter this market due to positive economic profit in the short run

As of June 2014, John Green's international bestselling novel, The Fault in Our Stars, had sold more than 10.7 million copies. In book publishing, fixed costs are high and marginal costs are low and fairly constant. Suppose that the marginal cost of the print version of The Fault in Our Stars is $2.50 per book and is the same for each book up to 20 million copies. Assume that this includes all variable costs. Explain why in this case marginal cost (MC) is a horizontal line, as is average variable cost (AVC). Suppose that the fixed cost of producing The Fault in Our Stars is $40 million
Marginal cost and variable cost are horizontal lines because these costs are UNCHANGING with output The average total cost of the book if the publisher produces 5 million copies is $10.50 The average total cost of the book if the publisher produces 10 million copies is $6.50 The average total cost of the book if the publisher produces 20 million copies is $4.50

For a given firm, MRPL = $250 and MRPK = $275 while PL = $50 and PK = $10. Is the firm maximizing profits? Why or why not? Identify a specific action that would increase this firm's profits.
No, because MRPL/PL is less than MRPK/PK. Holding the cost of production constant, this firm should use more CAPITAL and less LABOR
[Related to the Economics in Practice... in this section] In addition to gambling, Las Vegas is famous for its live production shows. Close to 100 shows are performed at various venues across the city on any given day, and many of the shows are multi-million dollar productions with months-long waiting lists for the best seats. Box office ticket prices range from less than $10 for a few of the smaller shows to over $200 for some of the major productions. In recent years, a number of these shows have begun offering tickets for sale at half price through discount ticket outlets. These half-price tickets are only available on the day of the show, on a first-come, first-served basis. Using the concept of marginal cost, explain why many of these productions have begun to offer these half-price tickets. Who among the following do you suppose are the least-likely customers to purchase show tickets through these discount ticket outlets? Can you think of any reasons why a production show would choose to not offer tickets in this manner?
Once a show has been scheduled and sufficient seats sold to make it PROFITABLE to stage, the marginal cost of filling remaining seats is probably NEAR ZERO. Even at half-price, the added REVENUE will exceed the negligible marginal cost of filling the remaining seats, enabling the show's promoter to enhance its PROFIT. People who are very 'picky' about seat quality (location). People having a rigid vacation itinerary and thus needing much certainty in their schedule. Individuals traveling with an ample entertainment budget. Ticket sales at regular prices may decline. Perceptions of the show's quality may suffer. The shows are always sold out in advance. All of the above are plausible. <----
The countries of Orion and Scorpius are small mountainous nations. Both produce granite and blueberries. Each nation has a labor force of 800. The table below gives production per month for each worker in each country. Assume productivity is constant and identical for each worker in each country. Orion workers --- 6 tons of granite --- 9 bushels of blueberries Scorpius workers --- 3 tons of granite --- 7 bushels of blueberries. Given that, without trade, each country will want to consume an equal number of tons of granite and bushels of blueberries.
Orion has a comparative advantage in the production of granite. Scorpius has a comparative advantage in the production of blueberries. Orion will produce and consume 2880 units of both granite and blueberries. Scorpius will produce and consume 1680 units of both granite and blueberries. Total production and consumption will be 4560 units of both granite and blueberries. If the countries decide to trade and each country completely specializes, Orion will produce 4800 tons of granite and Scorpius will produce 5600 bushels of blueberries. World production of granite increases by 240 tons and world production of blueberries increases by 1040 bushels. Assume 1,920 tons of granite are traded for 3,920 bushels of blueberries. Orion will consume 2880 tons of granite and 3920 bushels of blueberries. Scorpius will consume 1920 tons of granite and 1680 bushels of blueberries. Orion consumers increased consumption of blueberries and did not change consumption of granite. Scorpius consumers did not change consumption of blueberries and increased consumption of granite.

The firm will maximize profits by producing 200 units of output
You are given the following cost data: Total fixed costs are $15. If the price of output is $30, how many units of output will this firm produce (assuming the firm produces in the short run, in a competitive market)?
The firm will produce 3 units of output because this is where price equals marginal cost. Total revenue is $90 Total cost is $85 The profit of the firm is $5 In the short run, the firm will operate. In the long run, the firm will operate.
Related to the economics in practice: frozen foods and opportunity costs An analysis of a large-scale survey of consumer food purchases by Mark Aguiar and Erik Hurst indicates that retired people spend less for the same market basket of food than working people do. Use the concept of opportunity cost to explain this fact.
The opportunity cost of time for retired people is lower than the opportunity cost of time for working people, so retirees choose to spend more time shopping for lower-priced items compared to people who are still working.
Studies have fixed the short-run price elasticity of demand for gasoline at the pump at −0.20. Suppose that international hostilities lead to a sudden cut-off of crude oil supplies. As a result, U.S. supplies of refined gasoline drop 30 percent. If gasoline were selling for $1.50 per gallon before the cut-off, what new price would you expect to see in the coming months? (Hint: Use the absolute value of the gasoline elasticity coefficient and treat all values as positive.)
The price of gasoline will be $3.75 per gallon. Suppose that the government imposes a price ceiling on gas at $1.20 per gallon. How would the relationship between consumers and gas station owners change? It would cause a shortage of gasoline.
For normal goods, the substitution and income effects of a price decrease will

An externality exists when the cost or benefit resulting from some activity or transaction is experienced by parties external to the activity or transaction.
True
Sidecar recently filed suit against Uber, claiming that
Uber's market power allows it to engage in predatory pricing to harm its rivals
Related to the Economics in Practice: Substitution and Market Baskets As Uber continues to become a more convenient, and in many cases, less costly alternative to traditional taxi service for many of its customers, the income and substitution effects have an impact on the demand side of the market.
Using Uber compared to traditional taxi service makes the household better off, and real income has INCREASED. The income effect therefore allows MORE Uber service to be consumed. Since the relative price of using Uber compared to using a taxi is lower, households will substitute AWAY from using taxis and TOWARD using Uber more often.

Alexi and Tony own a food truck together that serves only two items, street tacos and Cuban sandwiches. Some customers purchase both goods together; therefore, they will always produce both goods. Alexi and Tony can sell all the street tacos and Cuban sandwiches that they are able to produce, and will split the revenue equally. Alexi --- 80 streets tacos --- 30 Cuban sandwiches Tony --- 40 street tacos --- 100 Cuban sandwiches
Alexi's opportunity cost of producing one taco is . .38 Cuban sandwiches. Tony's opportunity cost of producing one taco is 2.50 Cuban sandwiches. Tony has a comparative advantage in the production of Cuban sandwiches. Alexi has a comparative advantage in the production of street tacos. Assume that Alexi works 20 hours per week in the business. Further assume that Alexi devoted half of his time (10 of the 20 hours) to making street tacos and half of his time to making Cuban sandwiches. Suppose that Alexi spent all 20 hours of his time on street tacos and Tony spent 17 hours on Cuban sandwiches and 3 hours on street tacos. Combined they would produce a total of 1720 tacos and 1700 Cuban sandwiches. Suppose that Alexi and Tony can sell all their street tacos for $3.50 each and all their Cuban sandwiches for $3.50 each. Suppose each of them works 20 hours per week and they decide to completely specialize. That is, Alexi will spend all 20 hours on production of one good, and Tony will spend all 20 hours on production of the other good. How will they spend their time? Alexi will spend 20 hours on the production of street tacos. Tony will spend 20 hours on the production of Cuban sandwiches. Alexi will specialize in street taco production and earn $5600. Tony will specialize in Cuban sandwich production and earn $7000. Their maximum joint revenue is $12600 per week.
