Question
Chapter 9, Problem 1RQ
To determine
Determine the relation between wealth and saving.
Expert Solution & Answer
Explanation of Solution
The wealth measures the current value of a stock of assets owned by someone or society as a whole. That means, the wealth is a stock variable. For example, if a person says that ‘I have $10,000 in my bank account’, then it is the wealth of that person for that particular moment whereas saving is a flow variable, which is measured as per the unit of time. For example, if a person says that ‘I save $10 per week’, then it indicates one-week savings of that person. Here, the amount of wealth is increased at a growth rate of $20 per weeks.
Saving is not the only source that increases the wealth of a person. The value of wealth will also increase when the value of the assets held by an individual rise, this is called the

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

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.

Compute first total revenue for each level of output and fill in the TR column of the table. Next, compute marginal revenue for each level of output and fill in the MR column of the table.

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.
