When the opportunity cost of capital is matched with the benefits from adding to the capital stock, the marginal product of capital, we have:

Select one:

a the optimal production function

b the optimal stock of capital

Select one:

a 075

b 025*Y

c 025

d 075*Y

Australia’s recent large trade deficits:
