ECON 201 Comparative & Absolute Advantage
Introduction to Comparative and Absolute Advantage
Definition of Absolute Advantage:
The ability of a person or nation to produce more of a good with the same amount of resources than another.
Definition of Comparative Advantage:
The ability to produce a good at a lower opportunity cost than another producer.
Production Time Comparison
Objective: Determine who produces a meal in less time and how excellence in producing a meal is assessed based on time taken.
Method 1 - Time-based evaluation:
Whoever produces a unit (an ounce) in less time is deemed better.
Method 2 - Output-based evaluation:
If given a fixed time (e.g., eight hours), the focus shifts to who can produce more.
Understanding Absolute and Comparative Advantages
The first economist mentioned is Adam Smith:
He suggests that if one producer excels in the production of two goods, direct trade may not be beneficial.
The second economist mentioned is David Ricardo:
He posits that gains from trade can exist even if one producer is superior in both goods.
Example: If Ruby is better in both meat and potatoes, trade still can be beneficial.
Opportunity Cost Explained
Definition of Opportunity Cost:
The value of the next best alternative that is forgone when making a choice.
Example: Attending class (sacrificing tuition costs and potential earnings from working during those hours).
Calculating Opportunity Costs – Example Scenario
Frank's Production Capabilities:
In 8 hours, Frank can produce:
8 units of meat
32 units of potatoes
Opportunity cost of producing 8 meat:
32 potatoes foregone, hence the opportunity cost of 1 meat = 4 potatoes.
Ruby's Production Capabilities:
In 8 hours, Ruby can produce:
24 units of meat
48 units of potatoes
Opportunity cost of producing 24 meat:
48 potatoes foregone, hence the opportunity cost of 1 meat = 2 potatoes.
Insights on Comparative Advantage from Examples
Comparing Opportunity Costs:
Frank's opportunity cost of meat: 1 meat = 4 potatoes.
Ruby's opportunity cost of meat: 1 meat = 2 potatoes.
Determining Comparative Advantage:
Ruby has a lower opportunity cost in meat.
Frank has a lower opportunity cost in potatoes.
Conclusion: Ruby should specialize in meat while Frank should specialize in potatoes.
Specialization and Trade
Specialization Recommendations:
Ricardo advises specialization based on comparative advantage.
Frank should exclusively produce potatoes.
Ruby should exclusively produce meat.
Benefits of Trade:
Trade allows individuals to consume more than what they produce independently, reaching a point outside their production possibilities.
Terms of Trade
Definition and Example:
The agreed rate at which goods are exchanged.
Example of a fair trade: If Ruby offers 1 meat for 3 potatoes, it must be advantageous for both parties based on their opportunity costs.
The advantage arises when the terms of trade fall within the opportunity costs of both producers.
Production Possibilities and Trade Expansion
Without Trade - Consumption based on production possibilities only:
After Trade - Consumption can exceed the limits of individual production.
Importance of understanding the production possibilities frontier and how trade allows consumption expansion beyond individual capacity
Additional Trade Examples
Discussion on Naomi Osaka’s opportunity cost in terms of time versus money:
Comparison between Osaka (high earning potential) and Harry (lower earning potential).
U.S. and Japan Example:
American Worker’s statistics:
1 month: 1 car or 2 tons of food.
Japanese Worker’s statistics:
1 month: 1 car or 1 ton of food.
Opportunity Cost analysis helps determine what each nation should specialize in based on comparative advantages.
Summary of Key Terms and Concepts
Absolute Advantage: Being better in the production of all goods.
Comparative Advantage: Lower opportunity costs in production.
Opportunity Cost: What is given up to pursue an option.
Trade: Allowed to consume outside one's own production capabilities by leveraging comparative advantage.
