In this case, both and are nil. Exploiting this fact in the FOCs yields:
⏟ ⏟ Equating the expressions for shows that at the Case D optimal bundle: That is, the indifference curve will be tangent to the budget line slope. The actual amounts of goods 1 and 2 consumed
will be found by simultaneously solving these two equations:
13 University of Toronto, Department of Economics, ECO 204, 2013  2014 Here is an example showing the intuition behind this result: D Notice that Cases B, C and D are not mutually exclusive: {
Note that it is possible for all three cases to occur when as in the following example for linear utility function: 14 University of Toronto, Department of Economics, ECO 204, 2013  2014 C D B For utility models other than the linear utility function, when will we have only cases B, C, and D? Here’s the answer: { 15 University of Toronto, Department of Economics, ECO 204, 2013  2014 Question 4
Consider a (rational) consumer with a CobbDouglas utility function
defined over the consumption set
