Unformatted text preview: e price of Y is \$4 per unit? Instructions: Enter your answer as a whole number. 36 When Esther's income is \$20, the price of X is \$4, and the price of Y increases from \$1 to \$4, what is the uncompensated total change in Y? Instructions: Enter the absolute value. 9 What is the substitution effect on Y when the price of Y increases from \$1 to \$4? Instructions: Enter the absolute value. 6 What is the income effect on Y when the price of Y increases from \$1 to \$4? Instructions: Enter the absolute value. 3 What is Esther's compensating variation for the price change? Instructions: Enter your answer as a whole number. \$ 24 Explanation: MRSXY = ­ MUX / MUY = ­ Y / (X + 1). If X is increased and the level of utility is unchanged, Y must decrease to accommodate for the increase in X. Therefore, Y / (X + 1) must decrease, implying declining MRS. Esther's optimal choice when her income is \$20, the price of X is \$4, and the price of Y is \$1. The tangency between the indifference curve and the budget line implies: The budget equation implies: Therefore, Y = 4X + 4 = 12. Her utility in...
