The correct option is B
<u>Explanation:</u>
In an economy, planned investment spending is always equal to planned saving. If actual saving falls short of (exceeds) planned saving, then actual investment falls short of (exceeds) planned investment.
That is the other part of the saving paradox. If an economy produces too much, such that saving is greater than planned investment, inventory will build up, giving signal to producers to reduce output, to restore equilibrium. Such investment scheme is suitable only to communist countries. Keynes has another investment theory in his liquidity story. But investment theories are equally a posterior.
Therefore, Option B is correct
