2. Chapter 14 Production possibility frontiers. Case 1: linear technology... two people. Case 2: non-linear technology... two firms and two inputs.

3. Case 1 Two individuals A and B. Two goods 1 and 2. Individual A can produce 120 units of good 1 or 60 units of good 2... or any linear combination, for example 60 of good 1 and 30 of good 2. Individual B can produce 20 units of good 1 or 40 units of good 2... or any linear combination, for example 10 of good 1 and 20 of good 2. Let’s go to Maple.

4. Case 2 Two firms A and B. Two produced goods 1 e 2. Two inputs 1 and 2. Firm A has Cobb-Douglas technology with parameters a=0.63 and b=0.27. Firm B has Cobb-Douglas technology with parameters a=0.54 and b=0.36. The quantities of the two inputs in society are100 and 100. Society has to allocate the inputs to the two firms. Let’s go to Maple.

5. Chapter 14 Summary In a linear society the production possibility frontier is concave. In a non-linear society with decreasing returns to scale the production possibility frontier is concave.
