Absolute Advantage and Comparative Advantage
Comparative Advantage – can produce a product at a "lower opportunity cost". Absolute Advantage – can produce absolutely more with the same inputs.
Absolute Advantage – can produce absolutely more with the same inputs [more efficient]. I Can do 8 push-ups. I have an absolute advantage in the production of push-ups. I Can do 42 push-ups. LN Student LC Student Absolute Advantage – can produce absolutely faster with the same inputs [more efficient]. I’m more efficient. I can do the same work in 3 hours so I have an absolute advantage. I can clean that house in 4 hours. Future LN Housewife Future LC Housewife

(Djibouti/Canada) has anabsolute disadvantage in both, but a comparative advantage in fish. 29.Advantageous tradecan occur between the two when 1 wheat is exchangedfor (1/2.5/3) fish. We are going toturn inputs into outputs. In 20 hours, Djiboutican produce anoutput of 1 wheat or 2 fish. In 60 hours, Canadacan produce anoutput of 1 wheat or 3 fish. Looking at inputs [hours]
