You go to the movieplex where movies ordinarily cost $9. You are intending to see a movie for which you have a $3 off coupon good for only that movie at that time. However, when you get there you see a friend who asks if you would rather see a new release. Both movies start and end at the same time. If you decide to see the new release with your friend, what is your opportunity cost? a. the amount you value the first movie + $3 b. the amount you value the first movie + $9 c.$3 d.$9

Ans a. the amount you value the first movie + $3 It is because the opportunity cost is the value of all the benefits forgone while deciding to see the new release. In the above case, the benefits include 3 dollars coupon that could have been availed if one sees the first movie and the amount the person values for the first movie.

Assume for Brazil that the opportunity cost of each cashew is 100 peanuts. Which of these pairs of points could be on Brazil's production possibilities frontier? a. (200 cashews, 30,000 peanuts) and (150 cashews, 35,000 peanuts) b. (200 cashews, 40,000 peanuts) and (150 cashews, 30,000 peanuts) c. (300 cashews, 60,000 peanut) and (200 cashews, 50,000 peanuts) d. (300 cashews, 60,000 peanuts) and (200 cashews, 80,000 peanuts)

Ans a: It is given that opportunity cost of each cashew is 100 peanuts. This means in order to produce 1 cashew we have to sacrifice 100 Peanuts. We can also say that In order to produce 100 peanuts we have to sacrifice 1 cashew. Hence In order to produce 1 peanut Brazil have to sacrifice 1/100 cashews. Hence In order to 5000 peanuts we have to sacrifice (1/100)*5000 = 50 cashews). In option (a) initially Bangladesh have (200 Cashews , 30000 Peanuts) now suppose Bangladesh wants to produce 35000 Peanuts i.e. 35000 - 30000 = 5000 extra peanuts and as discussed above In order to 5000 peanuts we have to sacrifice (1/100)*5000 = 50 cashews). Hence Total cashew produced If they want to produce 35000 peanuts is 200 - 50 = 150 Cashews. Hence, (200 Cashews , 30000 Peanuts) and (150 Cashews , 35000 Peanuts) is on same production function.

After much consideration, you have chosen Ireland over Spain for your Study Abroad program next year.

The marginal benefit of going to Spain increases. b. The marginal cost of going to Spain increases. c. The marginal benefit of going to Ireland increases. d. The marginal cost of going to Ireland decreases.

Ans b: We have chosen to go to Ireland rather than Spain for study program. This decision can be reversed in two cases - 1. The marginal cost of going to Ireland increases. In such case, net benefit of going to Ireland will reduces. 2. The marginal benefit of going to Spain increases. In such case, net benefit of going to Spain will increase. So, We would be induced to change our decision if the marginal benefit of going to Spain increases.

Suppose the Federal Reserve announces that it will be making a change to a key interest rate to increase the money supply. This is likely because a. the Federal Reserve is worried about inflation. b. the Federal Reserve is worried about unemployment. c. the Federal Reserve is hoping to reduce the demand for goods and services. d. the Federal Reserve is worried that the economy is growing too quickly.

Ans b: We know from phillips curve, there is an inverse relationship between inflation rate and unemployment rate. Thus unemployment rate can be decreased by increasing inflation which can be done by increasing money supply. Or an increase in money supply will decrease interest rate leading to increase in investment and thus more capital formation, due to which more labor is required and thus unemployment decreases.

Ans c : A rational decisions makes focuses on logic and analysis against subjectivity and insight so they will take decisions only when marginal benefits are more than marginal cost for any decisions. So answer is c

Which of the following statements does not apply to a market economy? a. Firms decide whom to hire and what to produce. b. The "invisible hand" usually maximizes the income of society as a whole. c. Households decide which firms to work for and what to buy with their incomes. d. Government policies are the primary forces that guide the decisions of firms and households.

Ans c : Prices act as an invisible hand and not an visible hand to direct economic activities in allocating scarce resources.Price mechanism operates through demand and supply prices. At higher prices, consumers demand less so demand curve slopes downward showing inverse relationship between price and quantity demanded. However, suppliers are prompted to supply more if they can get higher prices so supply curve slopes upward due to the positive relationship between price and quantity supplied

Betty's Bakery bakes fresh bread every morning. Any bread not sold by the end of the day is thrown away. A loaf of bread costs Betty $2.00 to produce, and she prices loaves of bread at $3.50 per loaf. Suppose near the end of one day Betty still has 12 loaves of bread on hand. Which of the following is correct? a. Betty should only sell the remaining bread for $3.50 per loaf since that is the regular price. b. Betty should only sell the remaining bread for $2.00 per loaf or more since that is what the bread costs to make. c. Betty should be willing to sell the remaining bread for any price above $0 per loaf since she will have to throw it away if she does not sell it for something. d. Betty should just throw the bread away and change the price of her bread starting tomorrow to make sure she sells all of her bread each day.

Ans c : Since Betty is throwing the remaining loaves of bread so by selling them, she would be able to recover some of its fixed costs whereas by just throwing them away she is incurring a fixed cost $3.50 per loaves of bread sp Betty should minimize her cost by selling them at any price above $0.

Figure 3-9 Uzbekistan's Production Possibilities FrontierAzerbaijan's Production Possibilities Frontier Refer to Figure 3-9. If the production possibilities frontiers shown are each for two days of production, then which of the following combinations of bolts and nails could Uzbekistan and Azerbaijan together not make in a given 2-day production period? a. 9 bolts and 122 nails b. 21 bolts and 98 nails c. 36 bolts and 56 nails d. 47 bolts and 18 nails

Ans d : 47 bolts and 18 nails We can see from above production function that both functions opportunity cost of producing 30 bolts for Uzbekistan is 60 nails. Hence, opportunity cost of producing 1 bolts for Uzbekistan is 60/30 = 2 nails. Similarly opportunity cost of producing 1 bolts for Azerbaijan is 80/20 = 4 nails. Hence As opportunity cost of producing 1 bolts in Uzbekistan < opportunity cost of producing 1 bolt in Azerbaijan. Hence Uzbekistan will specialize in Bolts and Azerbaijan will specialize in nails. (a) 9 bolts and 122 nails - As Azerbaijan will specialize in nails, It will use its entire time on Nails and will produce 80 nails. We can see from the PPF that Uzbekistan can produce 9 bolts and 42 nails. Hence Option (a) is achievable (b) 21 bolts and 98 nails - As Azerbaijan will specialize in nails, It will use its entire time on Nails and will produce 80 nails. We can see from the PPF that Uzbekistan can produce 21 bolts and 18 nails. Hence Option (b) is achievable (c) 36 bolts and 56 nails - Uzbekistan will specialize in Bolts, It will use its entire time on bolts and will produce 30 bolts. We can see from the PPF that Azerbaijan can produce 6 bolts and 56 nails. Hence Option (c) is achievable (d) 47 bolts and 18 nails - Uzbekistan will specialize in Bolts, It will use its entire time on bolts and will produce 30 bolts. We can see from the PPF that Azerbaijan can produce 17 bolts and 12 nails. Hence Option (d) is not achievable. Hence option (d) is incorect. Note : PPF equation of Uzbekistan is N + 2B = 60 PPF equation of Azerbaijan is N + 4B = 80
