Quizplus · Accepted Answer

In a closed economy, national saving is equal to investment, so if national saving is greater than zero, investment must be positive. National saving is also the sum of public and private saving, so at least one must be positive. Additionally, $Y - C - G$ represents national saving, so it must be greater than zero.
