26. Answer the following questions about a market that is perfectly competitive: A)If the price is above the equilibrium price, would there be a shortage or a surplus? B)What will happen if the price is below the equilibrium price? C)During a shortage, how does the market respond until it once again reaches equilibrium?

A)If the price is above the equilibrium price there would be a surplus, because at prices above the equilibrium price there is more quantity supplied than demanded. B)If the price is below the equilibrium price there would be a shortage, because at prices below the equilibrium price there is more quantity demanded than supplied. C)A shortage in the market means that more quantity is demanded than is being supplied. This causes upward pressure on price because there are consumers who are willing to pay a higher price. To meet this demand, additional firms that are willing to supply the good at a higher price will enter the market. This cycle will continue until the equilibrium price is reached.

What is the best description of the demand for tennis balls, given that the quantity demanded of tennis balls drops by 72% when incomes increase by 48%?

Answer: Inferior goods see their quantity demanded increase as incomes decrease and the quantity demanded decrease as incomes increase. The negative value of the income elasticity of demand points to this negative relationship.

18. Suppose the U.S. government introduces a new anti-drug policy that 1) imposes stiffer penalties on individuals who sell and manufacture drugs in the United States and 2) stems the flow of illegal drugs from other countries into the United States. Given that most drugs are addictive, briefly explain whether you think this assumption is likely to hold.

Answer: Most drugs are addictive, suggesting that the price elasticity of demand will be low, between 0 and -1. Thus, it's unlikely that this policy will reduce expenditures on drugs.

18. Suppose the U.S. government introduces a new anti-drug policy that 1) imposes stiffer penalties on individuals who sell and manufacture drugs in the United States and 2) stems the flow of illegal drugs from other countries into the United States. d. If the government were to instead introduce a new anti-drug policy that 1) educated young people about the dangers of drug use and 2) increased funding for drug rehabilitation programs, how would the total expenditure on drugs be likely to change? Carefully, explain your answer, making reference to how such a policy would affect the equilibrium price and quantity of drugs.

Answer: Such a policy would reduce the demand for drugs. Thus, it would lower both the price and quantity of drugs. This would necessarily imply that total expenditures on drugs would fall.

6.Whole Foods cuts the price of organic milk kefir from $4 to $3. Sales increase from 1000 units to 1500 units. Calculate total revenues before and after the increase in price. Is the price elasticity of demand elastic, unitary or inelastic?

Answer: TR (before) = $4 *1000 = $4000. TR (after) = $3 * 1500 = $4500. Since the lower price generated more revenue we know demand is elastic.

20. If incomes increase by 48% and the quantity demanded of tennis balls drops by 72% as a result, what is the income elasticity of demand for tennis balls? Give your answer to one decimal.

Answer: The percentage change in quantity demanded (-72%) divided by the percentage increase in income (48%) gives an income elasticity of -1.5.

18. Use the following information to answer the questions below. Suppose that Oscar and Felix are roommates, and they want to find a way to divide up household chores—cooking meals and doing laundry. It takes Oscar 45 minutes to make a meal and 90 minutes to do a load of laundry. It takes Felix 60 minutes to make a meal and 60 minutes to do a load of laundry. (e) If Oscar and Felix trade, one load of laundry should trade for more than ____ meal(s) but fewer than ____ meal(s).

Answer: The terms of trade depend on each person's opportunity cost. For trade to be mutually beneficial, the price of one load of laundry should fall between each person's opportunity cost. Therefore, the price of one load of laundry should be between one and two meals.

30. Suppose that Bianca and Rosa each own a small farm. They both produce milk and apples. Each hour, Bianca can either produce 1 gallon of milk or 1 pound of apples, and Rosa can either produce 2 gallons of milk or 4 pounds of apples. Each works 4 hours a day. What is the opportunity cost to each of 1 pound of apples?

For Bianca, the OC of 1 pound of apples is 1 gallon of milk. For Rosa, the OC of 1 pound of apples is ½ of a gallon of milk.

30. Suppose that every day, Bianca and Rosa each spend 2 hours producing milk and 2 hours producing apples so that together they produce 6 gallons of milk and 10 pounds of apples. To show that this is not an efficient use of their time, find another way to divide up their time between producing milk and producing apples so that together they still can produce 6 gallons of milk but more than 10 pounds of apples.

If Bianca spends 4 hours a day producing milk and Rosa spends 1 hour a day producing milk and 3 hours a day producing apples, then together they can have 6 gallons of milk and 12 pounds of apples.

17. What is the most you can say about the relationship between the elasticity of demand at point A, point B and point C?

Let EX denote the elasticity of demand at point X. We know that E Cis more elastic than EA and EA is more elastic than EB.

15. Like a good economist, you calculated the opportunity cost of getting a college degree. Suppose that at your university, you will pay $12,000 each year for tuition, $2,000 each year for textbooks, and$10,000 per year for room and board. Before you left for college, your boss at Arby's offered you a job paying $30,000 per year. Assume that if you decided not to go to college, your parents would not let you live at home. What is your opportunity cost for four years of college?

Opportunity cost is the highest valued alternative that must be sacrificed to get something else. By spending $12,000 on tuition, you give up money that you could have spent on something else. By going to college, you give up the money you could have earned at a job. The opportunity cost of going to college should include the direct costs of getting an education (tuition and books) plus the indirect costs (income you could have earned if you did not go to college). Over four years, the opportunity cost is equal to: 4 ×($12,000 +$2,000+ $30,000) = $176,000 You do not include the cost of room and board because you would incur these living expenses even if you did not go to college.

30. Suppose that Bianca and Rosa each own a small farm. They both produce milk and apples. Each hour, Bianca can either produce 1 gallon of milk or 1 pound of apples, and Rosa can either produce 2 gallons of milk or 4 pounds of apples. Each works 4 hours a day. h. Who has the absolute advantage in producing apples? Briefly explain.

Rosa has the AA in the production of apples because it takes her less time to produce apples than Bianca (or, equivalently, Rosa can produce more pounds of apples per hour than Bianca)

29. Using a supply and demand model, show what happens to the equilibrium price and equilibrium quantity in the market for bananas if, holding all else constant, a study comes out that says eating bananas causes cardiac problems.

The demand curve would decrease (shift in) and price would decline and quantity would decline.

18. Suppose the U.S. government introduces a new anti-drug policy that 1) imposes stiffer penalties on individuals who sell and manufacture drugs in the United States and 2) stems the flow of illegal drugs from other countries into the United States. a. Using a supply and demand diagram, show how this policy is likely to affect the equilibrium price and quantity of drugs in the United States. Be sure to label the y-axis, the x-axis, the supply curve, the demand curve, any shifts in either curve induced by the new policy, and the equilibrium price and quantity before and after the new policy.

This policy will reduce the supply of drugs, but it will not affect the demand for drugs.

30. Suppose that Bianca and Rosa each own a small farm. They both produce milk and apples. Each hour, Bianca can either produce 1 gallon of milk or 1 pound of apples, and Rosa can either produce 2 gallons of milk or 4 pounds of apples. Each works 4 hours a day. Are there gains from specialization and trade in this case? If not, explain why not. If so, in which good should each specialize?

Yes. There are gains from specialization and trade. Rosa should specialize in the production of apples and Bianca should specialize in the production of milk.

12. You are considering going to LA to visit friends. A round trip plane ride takes 3 hours round trip and costs $400. A round trip bus ride takes 15 hours and costs $100. At what hourly rate would you be indifferent between taking the bus and the plane?

You save $300 at a cost of 12 hours. $300/12 = $25/hour

32. Consider the market for beer. a. Use a simple supply and demand graph to show the equilibrium price (P*) and quantity (Q*) of beer. Clearly label the supply curve, the demand curve, and the axes. b. Recently, the beer industry has been hit by a shortage of hops, which are used to make beer. At the same time, consumer income has been steadily increasing. On your graph, illustrate what will happen to the equilibrium price and quantity of beer as a result of the shortage of hops and the increase in consumer income. If you need to make additional assumptions in order to answer this question, clearly state what those assumptions are additional assumptions in order to answer this question, clearly state what those assumptions are.

a .See below. b. Assume that beer is a normal good. The equilibrium price will rise, but equilibrium quantity could increase or decrease depending on the size of the shifts in supply and demand.

4.How does money make the circular flow model more efficient? A) Having a common medium of exchange, like money, eliminates the need to barter. B)Money makes the product market more important than the resource market .C) Neither the product nor resource market can exist without money. D) Money gives firms an advantage over households since they have more money.

a) Having a common medium of exchange, like money, eliminates the need to barter.

30. For each of the following, draw a diagram that illustrates the likely effect on the market for eggs. Indicate in each case the impact on equilibrium price and equilibrium quantity. a. A surgeon general warning that high-cholesterol foods can cause heart attacks. b. A decrease in the price of bacon, a complementary product. c. An increase in the price of chicken feed. d. Caesar salad becomes popular at dinner parties. (The dressing is made with raw eggs.) e. A technological innovation that reduces egg breakage during packing.

a. The risk of heart attack will cause a change in preferences. Demand will go down. This will cause a decrease in quantity as well as a decrease in price. b. A decrease in the price of a complementary good will cause an increase in demand. This causes an increase in price and quantity. c. The increase in the price of chicken feed will constitute an increase in the cost of inputs on the supply side. This will cause a decrease in supply, which in turn causes higher prices and lower quantity. d. This is a change in preferences which increases demand for eggs. Price and quantity will rise. e. This technological innovation will cause an increase in supply. In this case, there will be and increase in supply and lower prices.

31. Consider the market for high-definition televisions (HDTVs). a. Scenario 1: Using a supply and demand graph, show what will happen to the current equilibrium price and quantity of HDTVs if people expect the price of HDTVs to fall in the future. b. scenario 2: Now, using a second supply and demand graph, show instead what will happen to the equilibrium price and quantity of HDTVs if the price of streaming services declines. c. Scenario 3: You observe that the price of HDTVs increases. Can you definitively conclude that there has been an increase in demand? If not, what besides an increase in demand could explain the price increase?

a.See below. Demand will decrease because consumers will want to wait until the price drops. Supply will increase because suppliers will want to sell now while the price is high. Current equilibrium price will fall. We cannot say what will happen to equilibrium quantity. (Note: The way it's drawn in the picture below, there's a very slight drop in the equilibrium quantity.) b. See below. The demand for HDTVs will increase. Current equilibrium price and quantity will increase. c. It is possible that the price increase could also be due to a decrease in supply.

18. Use the following information to answer the questions below .Suppose that Oscar and Felix are roommates, and they want to find a way to divide up household chores—cooking meals and doing laundry. It takes Oscar 45 minutes to make a meal and 90 minutes to do a load of laundry. It takes Felix 60 minutes to make a meal and 60 minutes to do a load of laundry. (c)Felix's opportunity cost of doing a load of laundry is ___meals.

answer 1 Answer for (b) and (c): It takes 90 minutes for Oscar to do a load of laundry. In that time, he could have made two meals (90:45). Therefore, Oscar's opportunity cost of one load of laundry is two meals. It would take 60 minutes for Felix to do a load of laundry. In that time, he could have made one meal (60:60). Therefore, Felix's opportunity cost of one load of laundry is one meal.

The graph shows two PPFs for Shiner Bock and Blue Bell Ice Cream. name 3 ways to shift the entire ppf out

better technology, more resources(such as labor, capital, time), temporarily working harder than you can sustain in the long run.

1. The New York City Subway banned dogs unless they fit in a bag. Here is the rule, "No person may bring any animal on or into any conveyance or facility unless enclosed in a container." But the rules do not say anything about the size of the animal, and as you can see from these pictures, some people got really creative in order to avoid paying a fine. This is an example of A) a shift in demand B) a shift in supply C) an unintended consequence D) comparative advantage

c) unintended consequence
