Transcribed Image Text:2-4. The land of Oz produces dreams (denoted by x) and wishes (denoted by y). The production
possibilities function in the current year is given by:
y = 2L²+ 3K²-0.4x²
where K is units of capital, and L is units of labor. Assume the current stock of resources is L= 20 and K
= 10. The marginal cost of x is given by the slope of the production possibilities frontier, PPF, a given
point and is a function of x. Notice the slope of this nonlinear function is not constant. In this case, the
slope, i'.y/i'.x, equals -0.8x (or, the first derivative dy/dx equals - 0.8x.)
a. Draw Oz's PPF and state whether resources are perfectly substitutable or not. Explain your answer.
