Question

Quizplus · Accepted Answer

A stock variable is a quantity that is measured at a specific point in time (a stock), such as government debt. Expenditure on consumer goods and labor wage are flow variables - they are measured over a period of time (a flow). Private investment can be both a stock and a flow variable, as it can refer to the total amount of investment made (a stock) or the rate at which investment is made (a flow). However, since the question asks for a stock variable specifically, D is the best choice.
