1. (3 pts.) On the graph below, break down the change resulting from the increase in the price of X into income and substitution effects. Note that in this case there is an increase in the price of X. Is X a normal or inferior good? 2. (3 pts.) On the graph below, break down the change resulting from the increase in the price of X into income and substitution effects. Note that in this case there is a decrease in the price of X. What kind of goods are these? 3. (4 pts.) If U = X0.5Y, I = 120, PX= 4, and PY=20, find the utility-maximizing combination of X and Y using the Lagrangian multiplier. Also find the MRS and the ratio of the prices at the utility-maximizing combination. Show your work on a separate page. a. Units of X b. Units of Y c. MRS d. Px/Py
