Quizplus · Accepted Answer

A stock variable is a measurement of a quantity at a particular point in time. Examples of stock variables include the number of people in a population, the inventory of a company, and the amount of money held by individuals or institutions. The money supply is a stock variable because it represents the total amount of money available in an economy at a specific point in time. The other options are flow variables, which represent a quantity over a period of time, such as GDP over a year, consumption spending over a month, and federal income tax over a fiscal year.
