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.

- Using the grapns below, wnicn snow the snort-run cost curves for 3 perfectly competitive firms in the same industry, determine whether the industry is in long-run equilibrium or not. Q Q Firm A QA MC ATC Output Firm B QB MC ATC Firm C MC ATC Output Output Qc 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.arrow_forwardConsider the table on the right, which shows the various revenue concepts for a perfectly competitive firm.

As the article indicates there are different measures of well-being. You are interested in creating a Hypothesis Test about the economic well-being of the area. Discuss the following issues: First, think about your research hypothesis and justify it briefly. Remember, a hypothesis is a well-thought and untested proposition. What is the null hypothesis? What is the parameter you are interested in? (i.e., the measure of well-being). Is it going to be a Lower-Tail, Upper-Tail or Two-Tailed test?

Samuelson We are now in the "blame phase" of the economic cycle. As the housing slump deepens and financial markets swing erratically, we've embarked on the usual search for culprits. Who got us into this mess? Our investigations will doubtlessly reveal, as they already have, much wishful thinking and miscalculation. They will also find incompetence, predatory behavior and probably some criminality. 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. The reality, I think, is that the economy follows its own Catch-22: By taking prosperity for granted, people perversely subvert prosperity.
