Suppose David spends his income (I) on two goods,
x
and
y
, whose market
prices are
p
x
and
p
y
, respectively. His preferences are represented by the utility
function
u
(
x;y
) =
lnx
+ 2
lny
(
MU
x
= 1
=x;MU
y
= 2
=y
).
a. Derive his demand functions for
x
and
y
. Are they homogeneous in
income and prices?
b. Assuming
I
= $60 and
p
x
= $1
, graph his demand curve for
y
.
c. Repeat part (b) for the case in which
p
x
=
$2
