An island economy produces only two goods, coconuts and pineapples. There are four people (A, B, C, and D) living on the island with the following preferences. Construct a set of indifference curve for each individual with pineapples on the vertical axis and coconuts on the horizontal axis. a. A likes both but has a strong preference for pineapples. b. B also likes both but has a strong preference for coconuts. c. C likes coconuts but doesn’t care for pineapples. d. D will only consume pineapples and coconuts in the fixed proportion of one pineapple to one coconut.

1. Sam is going to Baltimore for the day to watch his favorite baseball team (Orioles). Sam loves his Orioles, but he is addicted to drinking beer (B) and eating hotdogs (D) while watching his team. His utility function is: U = (B*D)1/2 a. Suppose Sam has $50 to spend on beer and hotdogs. Beer costs $5 a mug and a hotdog costs $4. Draw Sam's budget constraint. b. Suppose Sam spends all of his income on beer. How many mugs of beer can he buy? What is his utility? c. Will Sam's income allow him to reach a U = 5? d. If Sam buys 4 hotdogs, how many mugs of bear can he buy? What is his utility? e. What is the combination of beer and hotdogs that yield the highest utility? 2. Firm A's Price $20 $15 $20 $40 profit $35 profit Firm B's Price $37 profit $39 profit $15 $49 profit $38 profit $30 profit $35 profit a. Firms A and B are member of an oligopoly. Which solution will Firm A and B select? b. Is there a Nash equilibrium? If so, what is it? c. Which solution will Firm A and B select if Firm…

Question 3: Samantha has $3,000 to spend on two goods: sandwiches and beer. The price of a sandwich is $6 and price of a beer is $5. a) Draw Samantha's budget line. Put beer on the horizontal axis. b) If Samantha's optimal consumption bundle contains 400 sandwiches, how many beer does her optimal consumption bundle contain? Show her optimal consumption in the graph above. c) Draw Samantha's indifference curve crossing her optimal consumption bundle.

We have determined that Jenny's satisfaction from eating a Snickers bar is 30 utils, whereas Sarah's satisfaction from eating a Snickers bar is 15 utils. We also know that Jenny prefers Snickers bars over Milky Way bars. Which of the following statements can we say for sure are true? Drag the true statements to the box. Items (7 items) (Drag and drop into the appropriate area below) Jenny likes Snickers bars twice as much as Sarah does. Sarah likes Snickers bars more than Jenny likes Milky Way bars. Sarah likes Snickers bars more than Jenny does. Jenny likes Snickers bars more than Sarah does. Jenny's satisfaction from consuming a Milky Way bar must be less than 30 utils. There is not enough information to determine who likes Snickers bars the most. The price of the Snickers bar is needed in order to find out who likes it the most.

3. The classical dichotomy and the neutrality of money The classical dichotomy is the separation of real and nominal variables. The following questions test your understanding of this distinction. Hannah divides all of her income between spending on digital movie rentals and lattes. In 2015, she earned an hourly wage of $28.00, the price of a digital movie rental was $7.00, and the price of a latte was $4.00. Which of the following give the real value of a variable? Check all that apply. The price of a digital movie rental is $7.00 in 2015. Hannah's wage is $28.00 per hour in 2015. The price of a digital movie rental is 1.75 lattes in 2015. Which of the following give the nominal value of a variable? Check all that apply. The price of a latte is 0.57 digital movie rentals in 2015. Hannah's wage is 4 digital movie rentals per hour in 2015. The price of a latte is $4.00 in 2015. Suppose that the Fed sharply increases the money supply between 2015 and 2020. In 2020, Hannah's wage has…
