7. The effect of compensated price change on consumer well being is that the effect of consumers well being cannot be determined without knowing direction of price change. It is because the compensating variation of price change equals the resulting change in consumer surplus.
8. D is correct. The effect of compensated price change equals the substitution effect of the price change plus the income effect of the price change.
9. C is not true i.e. it isolates the influence of a change in relative prices.
10. For normal products, the income impact is Positive. In this way, when cost of a typical decent falls and results in increment in the obtaining power, wage impact will act an indistinguishable way from the substitution impact, that is, both will work towards expanding the amount requested of the great whose cost has fallen. The correct option is C.

3.5. The demand curves we studied in this chapter were constructed holding a person's nominal income constant-hence, changes in prices introduced changes in real income (that is, utility). Another way to draw a demand curve is to hold utility con- stant as prices change. That is, the person is "com pensated" for any effects that the prices have on his or her utility. Such compensated demand curves illus- trate only substitution effects, not income effects. Using this idea, show that:...
3. Keiko spends all her money on airtime for her mobile phone and gasoline for her car. Her preferences correspond to the utility function U(G,W) = W+ 20/G, where G stands for gallons of gasoline and W stands for mobile (wireless) minutes used in a week. (Remember, for that utility function, the marginal utility of gasoline is 10/VG, and the marginal utility of mobile minutes is 1.) Keiko can spend S40 and mobile minutes cost $0.50 per minute. Suppose the...
3. (10 points) Income and substitution effects A consumer's utility is given by U(x, y) = xy. Income is m and prices are given by p and Py (a) Find the demand functions for x and y. (b) What is demand for each good if p 2 and py 1 and income is m = (c) If price of x fell to pa 1, what is the consumer's new bundle? (d) How much of the response in the consumption of...
Emily's income is $120. She spends her entire income on books. Emily considers paperback and electronic books to be perfect substitutes, and she is always indifferent between one paperback book and one electronic book. Initially, the price of a paperback book is $15 and the price of an electronic book is $10. Then the price of a paperback book falls to $8. Which of the following statements is true? a) For paperback books, the income and substitution effects have the...
A.O B. 24 C. 40 D. 60 The demand curve for the new computer game, Rock and Roll Trivia, is given as follows: Q = 250 - 5P-0.1P. - 0.5P+0.2A-21 where P is the price of the game, P. is the price of a computer, P is the price of a diskette. A is the level of advertising, and Q is the level of income. Suppose P = 10. P. = 100. P. = 2. A = 5, and I...

Consider the case of a consumer who decides how many cups of coffee (denote by c) and cups of tea (denote by t) to consume every month. Assume the income endowment for caffeine needs is $300; the price of a cup of tea is $2 and the price of a cup of coffee is $3. a) Write down a Cobb‐Douglas utility function with exponents α=0.5 and 1‐α=0.5. b) Write down the budget constraint for this problem. c) Set up the...
