Assume consumer preferences satisfy the assumptions we discussed in class and consider a
generic consumer utility maximization problem:
max u(x,y)
x.y
s.t.
Pxx +Pyy ≤ 1
x>0, y20
Why do we need a budget constraint? Suppose we didn't have a budget constraint. How much x
and y would be consumed and what would be the consumer's utility?
=0
u(x". y") = 0
=
