Using Figure 8.1, a decrease in the quantity of aggregate demand resulting from the interest rate effect would be depicted as a movement from point

Suppose an economy with two goods (candy and desk) and two identical agents that is in a competitive equilibrium. The marginal cost of a piece of candy is given by MCc = 4Qc and the marginal cost of a desk is MCd = 2 + Qd. The current production level of candy (Qc) is 4 pieces and of desks (Qd) is 30. What can be said about the marginal utility of candy (MUc) and the Marginal utility of desks

(MUd)? A) 3MUc = MUd B) MUc = 0.5MUd C) MUc = MUd = 4 D) MUc = 2MUd

Bart operates a lemonade stand in front of his house. His father works at the Springfield Nuclear Power Plant. Which of the following is most likely to be true?

a. The long run is the same for the power plant as it is for the lemonade stand. b. The long run is longer for the power plant than it is for the lemonade stand. c. The long run is shorter for the power plant than it is for the lemonade stand. d. We cannot compare the long runs because these are different businesses. e. It's impossible for the power plant short run to be shorter than the lemonade stand's long run.
