Suppose Coke and Pepsi are perfect substitutes.
a. Derive the shape of the (uncompensated) demand curve.
b. Derive the shape of the compensated demand (or MWTP) curve.

What will be an ideal response?


a. Below, we begin with a relatively high price for Coke (making the slope of the budget steeper than 1) and ending with a relatively low price for Coke (making the slope of the budget less than 1). The optimal bundle goes from A to C.





b. The compensated demand curve is the horizontal portion of the uncompensated demand curve graphed above.
