Questions
What is Comparative Advantage?
Comparative advantage is the ability to produce something at a lower opportunity cost than others. David Ricardo showed in 1817 that England and Portugal both gained by specialising, even though Portugal was better at making both wine and cloth.
How do you use Comparative Advantage?
Use it to decide what to do yourself and what to hand off. Keep the tasks where your edge is largest, calculate what your hours are worth before doing everything yourself, and divide household chores sensibly. Just keep enough breadth to adapt, and make sure the gains are shared fairly.
When does Comparative Advantage matter?
Comparative Advantage is one of the 43 mental models for work, the situations where you ask: How do I get the right things done? Within that, it belongs to “Building skill”, alongside Deliberate Practice, Divergent Thinking vs Convergent Thinking and Generalist vs Specialists.
What is an example of Comparative Advantage?
Two stories show it at work: Ricardo’s cloth and wine (1817) and Foxconn (1974–2010s). Both are told in full in The Mental Models Daily Almanac, which has two stories for each of its 365 models.
Which mental models are related to Comparative Advantage?
Opportunity Costs, Specialisation and Circle of Competence. Comparative Advantage itself comes from economics.
