A. The quantity of money is measured at a given point in time.
B. It is sold in the equity market.
C. Money never loses purchasing power.
D. We must attach a time period to the measure.



Answer :

Final answer:

Money as a stock variable is measured at a specific point in time, representing a set quantity regardless of time periods.


Explanation:

Money as a stock variable means that the quantity of money is measured at a specific point in time, independent of time periods. For example, when we know the balance in a checking account is $1,000, it is a stock variable as it represents a specific amount at a given moment. Stock variables are contrasted with flow variables like income, which require a time dimension to be meaningful.
