Expert Solution & Answer
Explanation of Solution
People can choose a diversified portfolio to get a high return with low risk. If an individual only invests in stock market, it will result in a higher risk. But he invests in a stock market by holding a diverse portfolio; he can achieve a good high return with least risk. It is also a good idea when the person uses some social security program to make his investments. If the person invests in the Old Age and Survivor Insurance, he will get a benefit from the program at the time of his retirement.

Wolfgang is a typical producer in a perfectly
competitive piano industry (i.e., all other producers of
pianos face the same costs as Wolfgang). The
following production and cost data apply to the long run
as well as the short run. Fixed costs (rent) are
unrecoverable in the short run and are equal to $2400
per month. Variable costs consist of raw
materials (wire, wood, plastic), which cost $1000
per piano, and the $40 per hour opportunity cost
of Wolfgang's time. Wolfgang's production function is
given in the table at right.
Wolfgang will shut down if the price per piano is less
than
OA. $3000.
B. $4000.

If Firms A, B and C are in the same industry, is this industry in long-run equilibrium?
○ A. Yes, because P = MC = MR for each of the 3 firms.
○ B. No, because Firm A is not producing at a profit-maximizing level of output.
○ C. Yes, because all 3 firms are producing at their minimum average total cost.
OD. The answer is uncertain since it's unknown whether the firms are producing at the minimum efficient scale or not.
○ E. No, because if the industry were in equilibrium, all 3 firms would be earning zero economic profits.

But let me suggest that, though inevitable and necessary, this exercise is also simplistic and deceptive. -- business It assumes that, absent mistakes and misdeeds, we might remain in a permanent paradise of powerful income and wealth growth.
