Opportunity Cost Framework
機會成本框架 · Source: 經典經濟學
Resource allocation decisions — how to deploy time, money, attention; especially when you're treating "do nothing" as a free option
Core Concept
The true cost of a choice includes not just its direct cost, but the value of the best alternative you give up. Opportunity cost is often the most underweighted factor in decisions.
✓ When to use this
When considering investing time, money, or attention into an opportunity. "Is this worth it?" is never an isolated question — the real answer is "is this more worth it than the next-best thing I could do?"
✗ When not to use this
Skip in emergencies or no-choice scenarios — reality has already narrowed the option set. Also unsuitable for ruminating on already-committed investments — it becomes sunk-cost anxiety.
Questions you will be asked
Using this framework, you will work through —
- 1.What are you considering investing, and in what?
- 2.If you make this decision, what two to three alternatives would you be giving up?
- 3.What value would the best of those alternatives bring you?
- …and 3 more
