1.
Alex spends his money on food, a normal good, and all other goods (also normal). Decompose the total effect of a decrease in food prices into substitution effects and income effects. (i.e. draw the graph)
2.If Maria’s utility function is U = 2q1
0.5+ q2:
a.What are her demand functions for the two goods?
b.What are her income elasticity for the two goods?
c.What are her Engel Curve for the two goods?
3.Bill’s utility function is U = 2ln(q1) + 2ln(q2). What is his compensated demand function for q1?
4.Siggi’s quasilinear utility function isU = 4ln(q1)
+ q2. His budget for these goods is Y = 10. Originally, the prices are p1= p2= 1. However, the price of the first good rises to p1= 2. Discuss the substitution, income, and total effect on the demand for q1.
5.If the inverse demand function for radios is p = a – bq, what is the consumer surplus if the price is a/2?
6.Marvin has a Cobb-Douglas utility function, U = q1
0.5q2
0.5, his income is Y = 100, and , initially he faces prices of p1= 1 and p2= 2. If p1increases to 2, what are his CV,
CS, and EV?
7.Fangwen’s utility is U(q1,q2)= q1+ q2.The price of each good is $1, and her monthly income is $4,000. Her firm wants her to relocate to another city where the price of q2is $2, but the price of q1and her income remain constant. What would be her equivalent variation or compensating variation?
