Exercise 11 Consider a consumer with the following utility function for the consumption of good x and of good yi U（x,y）=2-5- 1ー> Knowing that the marginal utility of good x is i and the marginal utility of good y is i, What is the optimal combination of x and y, given that consumer's income is 1200$ and the prices of good x and y are respectively 1$ and 4$? What is the optimal combination of x and y if the price of good x increases to 4$? iii. Decompose in terms of substitution and income effect, the change in the optimal demand of x, following the change in the price of x.

Suppose you are in charge of a tol bridge that costs essentially nothing to operate. The demand for bridge crossings Q is given by: P= 15 - 1/2Q a) How marny people would cross the bridge if there were no toll? b) What is the loss of consumer surplus associated with a bridge toll of $5? c) The tol-bridge operator is considering an increase in the toll to $7. At this higher price, how many people would cross the bridge? Would the tol-bridge revenue increase or decrease? What does your answer tell you about the elasticity of demand? d) Find the lost consumer surplus associated with the increase in the price of the toll from $5 to $7

The director of a theater company is considering changing the way he prices tickets. He has hired an economic consulting firm to estimate the demand for tickets. The firm has classified people who go to the theater into two groups, and has come up with two demand functions. The demand curves for the general public (Qg) and students (Qs) are given below: Qg =500-5P Qs=200-4P Which of the following statement(s) is (are) wrong? a) At the price of 35, the general public demands 175 tickets b) The vertical intercept of the students demand curve is 100 c) At the price of 35, the price elasticity of demand for students and the general public are respectively -2.33 and -0.54 d) If the director increases the price the general public pay from 35 to 38.5 , the quantity demanded falls by 5.4% but the director's revenue increases

John has a monthly income of I=400 and a utility function of the type: u(x, y)=min{2x, y} the price of good x is 3 while the price of good y is 4. i. what is John's most preferred ratio of consuming good x and good y? ii. find John's equilibrium quantities for good x and y?
