Question
Chapter 11, Problem 1QP
To determine
The three functions of money.
Expert Solution & Answer
Explanation of Solution
Money is an asset that is widely accepted as a means of payment. The main functions of money are listed below:
- Medium of exchange: Money acts as a medium of exchange to pay for the goods and service.
- Unit of account: As a unit of account, money is used to measure the value of goods and services in the economy.
- Store of value: Money has the store of value. This function facilitates the exchange of goods and services over time.
Thus, the three main functions of money are medium of exchange, unit of account, and store of value.
Economics Concept Introduction

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.

- Consider the table on the right, which shows the various revenue concepts for a perfectly competitive firm. Suppose the firm faces a constant market price of $4. 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. (Marginal revenue at each level of output is computed using total revenue for two successive levels of output. For example, marginal revenue at 160 uses total revenue for output levels 120 and 160.)

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.
