E201 Spring 2009 Homework #4 The questions below draw from the material in the reading on Marginal Utility Analysis (at ereserves ( The password is: water. As with other problem sets, I encourage you to work on these problems in a small group, but the answers you hand in at CL must be your own. 1. Complete the following table: Units TU X MU X MU X /PX TU Y MU Y MU Y /P Y 1 10 5 2 17 9 3 20 12 4 22 14 5 23 15 a. Suppose that the consumer has $17.00 income to spend on two goods, X and Y. If the price of X is $2 per unit and the price of Y is $3, which good does this consumer purchase first? Why? b. How much of X and Y will the consumer purchase if all income is spent? c.

If the price of socks is less than the price of T-shirts, what will a rational consumer do? 4. Suppose that the MU of ice cream is 100 utils and the price of ice cream is $2.00. If the price of cookies is $1, and the consumer is in equilibrium, what is the MU of a cookie? 5. Joe Cool wants to purchase either a Mazda Miata or a Porsche. Suppose that the Miata yields 100,000 jollies, while the Porsche yields 200,000. The price of the Miata is $18,000 while the Porsche is $54,000.
