Economics 1100: Intermediate Microeconomics
Spring 2011
Problem Set 3
1.
By studying, Wendy can produce a higher grade, G, on an upcoming economics exam. Her production function
for G depends on the number of hours she studies calculus problems, C, and the number of hours she studies
economics problems, E. Specifically,
G
W
= 2.5C
0.36
E
0.64
. Her roommate Denise’s grade production function is
G
D
= 2.5C
0.25
E
0.75
.
a.
What are Wendy’s and Denise’s marginal productivity from studying calculus problems?
b.
What are their marginal rate of technical substitution between studying the two types of problems?
c.
Is it possible for two production functions to have different marginal product functions but the same
marginal rate of technical substitution functions? Explain.
2.
Under what conditions do the following production functions exhibit decreasing, constant, or increasing returns to
scale?
