Josel owns two fields: Green
4. Joint PPF and quantity restriction
field and Blue field. He can produce corn and wheat. Green field has 80 acres, and it
takes 10 acres to produce 1 bushel of corn and 20 acres to produce 1 bushel of wheat.
Blue field has 100 acres, and it takes 20 acres to produce 1 bushel of corn and 10
acres to produce 1 bushel of wheat. Suppose that the government imposes a quantity
restriction on only corn. Specifically,
A quantity restriction of 4 bushels of corn in Green field. That is, Green field is
allowed to produce at most 4 bushels of corn, and
A quantity restriction of 2 bushels of corn in Blue field. That is, Blue field is
allowed to produce at most 2 bushels of corn.
(a)
Sketch the joint PPF. Clearly label your graph (i.e., indicate values
for slopes, intercept(s), endpoint (s), and kink(s)).
Suppose the production function in an economy is Y = K0.SL05, where K is the amount of capital and L is the amount of labor.
The economy begins with 25 units of capital and 25 units of labor.

The function used to model production was of the form: (1) P(L, K) = 6LªK!-a where P is total production (monetary value of goods produced in the year); L, the amount of work (total number of person-hours worked in a year); and K, the amount of capital invested (monetary value of machinery, equipment and buildings). In these terms, the hypotheses made by Cobb and Douglas can be stated as follows: (i) If either labor or capital cancel each other out, so does production. (ii) The marginal productivity of labor is proportional to the amount of output per unit of work. (iii) The marginal productivity of capital is proportional to the amount of production per unit of сapital. 1.
