Memory Aids
Mnemonic
Think of standing at a fork in the road. Choosing one path (opportunity) means you can't take the other—the lost path is the cost.
Conceptual Metaphor
CHOICE IS A TRANSACTION (You 'pay' for a choice with the lost benefits of the alternative).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'стоимость возможности'. The standard economic term is 'альтернативная стоимость'.
- Do not confuse with 'издержки' (costs/expenses) which is broader.
- Ensure the concept of a *forgone benefit* is central, not just any cost.
Common Mistakes
- Using it to mean any cost, rather than the cost of the *next best alternative*.
- Confusing it with 'sunk cost' (a past cost that cannot be recovered).
- Omitting the comparative element ('best' alternative).

FAQ
Frequently Asked Questions
No. It can be measured in time, pleasure, utility, or any other benefit that is sacrificed.
Opportunity cost is a forward-looking cost of a forgone alternative. A sunk cost is a past expense that cannot be recovered and should not influence future decisions.
Yes, but only if resources are not scarce. If there is a free good with unlimited supply (like air to breathe), choosing it has no opportunity cost.
Often not explicitly, but the concept underlies most rational decision-making, where we implicitly weigh alternatives.
