03Measurement

Stock vs. Flow Variables

A stock variable measures a level at a point in time. A flow variable measures a rate of change over a period of time.

Important

In this lesson, "stock variable" does not mean common stock. It means a quantity measured at a point in time.

Now that you can separate price, value, accounting, and measurement, the next step is understanding how corporations and households move cash through their own financial systems.

Lesson takeaway

  • Price discovery works even with incomplete information.
  • Accounting provides the vocabulary and structure of finance.
  • Stock variables are measured at a point in time; flow variables over a period.
