The idea
What is Comparative advantage?
Comparative advantage is the principle, set out by David Ricardo, that countries gain by specialising in what they produce at the lowest opportunity cost and trading for the rest, even if one of them is better at making everything. If India gives up less wheat to make a unit of cloth than Australia does, India has the comparative advantage in cloth and Australia in wheat; each specialising and trading raises total output and lets both consume more than they could alone.
Where it appears: Class 12 ISC and CBSE Economics, IGCSE and A Level Economics, IB and AP Macroeconomics, UPSC prelims.
Where learners get stuck
Why Comparative advantage is hard
Learners confuse absolute advantage (being better at something) with comparative advantage (giving up less to do it), and cannot compute opportunity costs from a two-goods table to decide who should make what.
The picture a good explanation starts with: A two-country, two-goods table of output per worker, converted step by step into opportunity-cost ratios, with the specialisation pattern and the gains from trade shown as extra output.
A lesson, step by step

02
Plan

03
Explain
It explains Comparative advantage out loud while the picture builds step by step, pitched to your level (Class 12 ISC and CBSE Economics and up).
04
Interrupt
Say "wait, why?" or type a doubt: it stops, answers over the picture, and carries on. Ask for a different explanation any time.
