  1. Suppose the market prices are px=15, and py=8. Which of the following exchanges does this little “world” allow?
  1. 15/23 units of good x for 1 unit of good y
  2. 1 unit of good x for 8/15 units of good y
  3. 15/8 units of good x for 1 unit of good y
  4. 8 units of good x for 15 units of good y
  5. 15 units of good x for 8 units of good y

Expert Solution

Option B

In equilibrium, 15X=8Y

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.
