The idea
Comparative advantage concerns lower opportunity cost, not simply higher absolute productivity. People can gain from specialization when their relative tradeoffs differ. The relevant question is what each person gives up to produce one more unit of a particular output.
Worked example
In an hour, Noor can edit six pages or design three graphics; Ellis can edit four pages or design one graphic. Noor is faster at both tasks. But one graphic costs Noor two pages of editing, while it costs Ellis four. Noor has the lower opportunity cost in graphics; Ellis has the lower opportunity cost in editing. Assigning some graphics to Noor and editing to Ellis can expand combined output compared with splitting both tasks identically.
Use it carefully
The calculation assumes transferable work, stable productivity, and manageable coordination costs. Real teams also need learning, resilience, fairness, and meaningful work. Permanent specialization can leave people dependent on one expert or deny development opportunities. Use the comparison to reveal potential gains, then account for quality differences and organizational goals. Absolute speed alone cannot determine the best allocation.
FROM UNDERSTANDING TO ACTION
Put it to work.
Calculate each person’s opportunity cost in the example. Add a coordination cost and decide whether the allocation still helps.
