Suppose there are only two goods in the economy: Yo-yos and Marbles. Bob only cares about his consumption of Yo-yos; the more Yo-yos he has the happier he is, regardless of his consumption of Marbles. In contrast, Lucy only cares about his consumption of Marbles; the more Marbles she has the happier she is, regardless of her consumption of Yo-yos. (a) Draw Bob's indifference curves, putting Yo-yos in the x-axis and Marbles in the y-axis. (b) Draw Lucy's indifference curves, putting Yo-yos in the x-axis and Marbles in the y-axis. (c) Do Bob's and Lucy's preferences comply with the property of diminishing marginal rate of substitution?

Belinda loves chocolate and always thinks that more is better than less. Belinda thinks that a few piano lessons would be worse than none at all, but if she had enough piano lessons to get good at playing the piano, she would prefer more lessons to less. Draw a graph with chocolate on the horizontal axis and piano lessons on the vertical axis. On your graph sketch two indifference curves for Belinda that would be consistent with this story. Label the better of the two indifference curves AA and the worse one BB.   Note:- Do not provide handwritten solution. Maintain accuracy and quality in your answer. Take care of plagiarism.

Andrea has a budget of £21 to spend on toothbrushes and tooth paste. He does not receive any utility from owning a toothbrush, but for the consumption of every tube of tooth paste he gains a utility of 2 utils – but only if he owns a tooth brush. Without a tooth brush, Andrea gains no utility from consuming tooth paste. In addition, after consuming 10 tubes of tooth paste, a toothbrush needs to be replaced, i.e., Andrea needs to buy a new one. The current price of tooth brushes on the market is £5 and the current price for tooth paste is £1 per tube. Assume that Andrea aims to maximise consumer surplus. wwwwwww a) In a graph, draw total utility as a function of number of toothpaste tubes, assuming that Andrea buys 1 tooth brush. b) How many tubes will Andrea buy if he wants to maximise consumer surplus, assuming that Andrea can buy any amount of tooth brushes? What is Andrea's total consumer surplus? c) How many tubes will he buy if the current price is £0.50 per tube? d) Find Andrea's…

7) A consumer has to choose the optimal amount of cheese and crackers to purchase. He or she has drawn his or her budget constraint (BC) and indifference curves on a graph with the amount of cheese (in ounces) on the horizontal axis and the amount of crackers (in packages) on the vertical axis. Which of the following statements is true if the price of crackers declines? The BC shifts to the left (down). The BC shifts to the right (up). The BC rotates such that it intersects the horizontal axis at the same point as before and intersects the vertical axis at a lower point. The BC rotates such that it intersects the horizontal axis at the same point as before and intersects the vertical axis at a higher point.
