- Paul, Noel, and Sandi work in a bakery where they make pies and cakes. In one day, Paul can make 5 pies or 5 cakes or any combination of these two goods that lie on the same line containing these two production points. Noel can make 30 pies or 10 cakes or any combination of these two goods that lie on the same line containing these two production points. Sandi can make 12 pies or 6 cakes or any combination of these two goods that lie on the same line containing these two production points. Assume that the production possibility frontier (PPF) of each person is a straight line. What are the opportunity costs of producing 1 pie in terms of the number of cakes for Paul, Noel, and Sandi? a. The opportunity cost of producing 1 pie for Paul is 1 cake; for Noel is one third of a cake; for Sandi is one half of a cake. b. The opportunity cost of producing 1 pie for Paul is 1 cake; for Noel is three cakes; for Sandi is one half of a cake. c. The opportunity cost of…Consider Tralfamadore, a hypothetical country that produces only burritos. In 2017, a burrito is priced at $2.00. Complete the first row of the table with the quantity of burritos that can be bought with $700. Hint: In this problem, assume it is not possible to buy a fraction of a burrito, and always round down to the nearest whole burrito. For example, if your calculations result in 1.5 burritos, the answer should be 1 burrito. Year Price of a Burrito Burritos Bought with $700 (Dollars) (Quantity) 2017 2.00 2018 Suppose the government of Tralfamadore cannot raise sufficient tax revenue to pay its debts. In order to meet its debt obligations, the government prints money. As a result, the money supply rises by 40% by 2018. Assuming monetary neutrality holds, complete the second row of the table with the new price of a burrito and the new quantity of burritos that can be bought with $700 in 2018. The impact of the government's decision…Alice and Bob are both capable of producing goods X and Y. In one hour, Alice can produce one unit of each good. In the same amount of time, Bob can produce two units of each good. If Alice and Bob have access to the same amount of time, calculate the difference between the slope of Alice's PPF and the slope of Bob's PPF. (round to two decimal places if necessary)
- 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.If good 1 is a neutral, what is its marginal rate of substitution for good 2? If good 1 and good 2 are perfect-substitute goods, what is the marginal rate of substitution?In the economy, is there only one efficient combination of goods?
- Say that Laura (L), Maureen (M), and Carrie (C) are three individuals who are contemplating the purchase of some amount of good X. Units of X can be produced at a constant marginal cost of 24. The following equations show how the marginal benefit (M B) that each individual places on X varies with the quantity she consumes: L: MB(L) = 30 - X M: MB(M) = 24 - X C: (MB(C) = 20 - X (a) How much of this good should they purchase if X is a private good? (b) How much of this good should they purchase if X is a public good? (c) Construct a diagram to illustrate your answer to part b.Carol and Bob both consume the same goods in an economy of pure exchange. Carol is initially endowed with 9 units of good 1 and 6 units of good 2. Bob is initially endowed with 18 units of good 1 and 3 units of good 2. They both have the utility function U(x₁, x₂) = 1/3 2/3 x1³x2³. If we set good 1 as the numeraire (so that p. = $1), what will the equilibrium price of good 2 be?Economist George Stigler once wrote that, according to consumer theory, “if consumers do not buy less of a commodity when their incomes rise, they will surely buy less when the price of the commodity rises.” What kind of commodity was Stigler referring to? A normal good An inferior good When the price of this commodity rises, the substitution effect is (positive / negative) and the income effect is (positive / negative). So the net result for consumption of this commodity (depends on which effect dominates / is a decrease / is an increase).
- A farmer produces both green beans and corn. The farmer must give up 31 bushels of corn to get 7 more bushels of green beans. If the rate of transformation (or tradeoff) between the two goods is constant, then the opportunity cost of 1 bushel of green beans in terms of bushel of corn is? The result should be given to two decimal places in absolute value (e.g if the result is 3.678, write 3.68, if the result is -3, write 3.00.) Your Answer:Consider two commodities: toy cars and batteries. Each toy car takes three batteries to operate. Suppose Andy enjoys a toy car only if it moves and Andy has no other toy that needs battery. That is, one toy car and three batteries are a set of perfect complements to Andy. Task 1: Let x1 >= 0 be the quantity of toy cars and x2 >= 0 be the quantity of batteries. FindafunctionU(x1, x2)thatrepresentsthispreference. Task 2: Draw Andy's indifference curves going through bundles (2, 3), (4, 3) and (5, 5) in the commodity space in the same graph. How does Andy's preference order these 3 bundles in terms of > or ? Task 3: What mathematical expression describes the line formed by all the corners of the indifference curves?What do you mean by complementary goods give two examples of the goods which are complement to each other?
