Quizplus · Accepted Answer

A stock variable is a measure of a quantity at a given point in time. Sales by corporations and borrowing by the federal government are flow variables, which measure the change in a quantity over a given period of time. Net exports can be a flow or a stock variable depending on how it is measured. Household wealth, on the other hand, is a stock variable as it represents the total value of assets owned by households at a specific point in time.
