Which of the following is the odd one out?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Ex post investment
Ex ante means planned; ex post means actual. Three options are planned values; one is an actual value.
Option (1) Ex ante consumption — Planned value. Ex ante consumption is the value of planned consumption.
Option (2) Ex ante investment — Planned value. Ex ante investment is the value of planned investment.
Option (3) Ex post investment — Actual value (odd one out). Ex post investment is what actually happened, unsold stocks included.
Option (4) Ex ante aggregate demand — Planned value. The AD function shows ex ante, that is planned, demand.
