Suppose income I = $160, Px = $20, & Py = $20.

Find the combination of X and Y that maximizes utility.
Calculate Consumers’ surplus of X, CSx = TUx – TEx, total utility minus total expenditures such that total expenditures TEx = Px.X. Do the same for commodity Y. Calculate consumers’ surplus CSy = TUy – TEy, where total expenditures TEy = Py.Y.
Suppose Py rises to Py’ = $40. Find the combination of X and Y that maximizes utility.
Calculate CSy’ the new consumers’ surplus of Y, CSy’ = TUy’ – TEy’.
Draw the demand curve for commodity Y. Is it downward sloping?
Challenging question: Find the equation for demand pertaining to commodity Y such that Py = a – bY. In other words, find the parameters a and b.

Suppose a consumer has preferences given by U(X,Y) = MIN[2X,Y]. Suppose PX = 1 and PY = 2. Draw the Income Consumption Curve for this consumer for income values • M = 100 • M = 200 • M = 300 To do this, carefully draw the budget constraints associated with each of the prices for good X, and indicate the bundle that the consumer chooses in each case. Also, be sure to label your graph accurately.

1. Consider the preferences of an individual over two goods, x and y, with prices px and py and income I. (a) If the individual's preferences can be represented by the utility function u(x,y) =2x1/2 + y, what is the marginal rate of substitution? What does this MRS imply about how this consumer would trade y for x? Are the underlying preferences homothetic (explain)?
