BUT …

Income (Y) = C + S + I Yeah, I know …

Just play along

or pretend for a moment that you’re not an economist

Setting aside the economics definitions, the usual use of the words “savings” and “investment” are derived from separate psychological impulses

If you must be an economist we could say Y = C + Sp + Ss, dividing Saving into precautionary and speculative motives

But … Holding Consumption constant, increases of Saving require deceases of

Investment and vice versa

We Save from Fear

We Invest from Hope

We Invest to get ahead

We Save to keep from falling behind

At some point, Investing more will increase fear by reducing Savings.

The farmer’s problem is to maximize a utility function whose arguments are Consumption, Fear and Hope, subject

to Y = C + S + I
