(a) Derive demand for each good for the following tastes: u(x, y) = αlnx + y. (Note: To fully specify the demand relationship in this case, you need to watch out for corner solutions.) MUx = α / x and MUy = 1.
(b) Graph the Engel curves for x and y - carefully labeling slopes and intercepts.
(c) Is the good x substitute / complement for good y? Is the good y substitute / complement for good x?
