7. Another example of opportunity cost is a company's cost of capital. Suppose a manufacturer wants to add microwave ovens to its product line. To do this, it must invest $500,000 in new equipment.

Besides the original investment, the company estimates it would spend $200,000 per year on production
costs for labor and materials. It also estimates that it could sell about $225,000 worth of microwave ovens
each year. Would it benefit the company to manufacture the microwave ovens if it could earn 10 percent
interest by purchasing U. S. Treasury bonds with the $500,000? Explain your answer.

the answer is "b.the increased supply will create a surplus. "

the essential thought behind price controls is straightforward - utilize the power of law to modify the equilibrium of a market. for instance, the legislature may choose that the steel business needs to survive, and in this way pass a law to set a value floor on steel. this implies all steel sold must offer at or over the floor value, which must be set over the equilibrium cost for it to have any impact. the switch could likewise happen - the administration can choose that steel is excessively costly and set a value roof underneath its equilibrium value, with the goal that all steel must be sold at or beneath that ceiling.
