Econ: international trade
Introduction
Welcome to the lecture on international trade
Despite bad weather, appreciation for attendance
Overview of International Trade
Today's focus: International Trade I and II
Starting with a slideshow discussing trade concepts
Pencil Factory Example
Picture of a pencil factory shown
Mention of the essay "I, Pencil"
Theme: Complex production processes of simple objects
Key concept: A single pencil requires resources and labor from multiple countries
Components of the pencil: Graphite from Sri Lanka, wood from California, etc.
Significance: Reflects on the interdependence due to international trade
Comparative Advantage
Recap of previous lessons on trade and comparative advantage
Definition of economic surplus: Maximization when tasks are allocated based on the lowest opportunity cost
Comparative Advantage: The ability to produce a good at a lower opportunity cost than others
Does not imply overall superiority; rather it means being relatively better at a task
Example: A baker may not bake as well as a basketball player but has a lower opportunity cost in baking compared to basketball
Specialization and Trade
Implications of comparative advantage:
Specialization: Focus on tasks where one has a comparative advantage
Trade: Purchasing goods one is not relatively good at producing
Each individual maximizes productivity by focusing on their strengths
Roommate Example:
Jamie focuses on cooking, while Helen focuses on vacuuming
Result: Higher total production (more meals)
Cooperation vs Competition
Emphasis on the benefits of cooperation in resource allocation (e.g., chores)
Trade is about minimizing costs and maximizing output through cooperation
Introduction to International Trade
Transition from domestic to international trade scenarios
Borders do not undermine the principles of comparative advantage in trade
Importance of studying international trade:
Terminological differences (imports vs. exports)
Regulation differences (domestic vs. international)
Political opposition to foreign trade
Sources of Comparative Advantage
Understanding why certain countries specialize in specific goods:
Relative Abundance of Resources:
Ex: New Zealand: abundant land and sheep, exports wool
Ex: Canada: forests, exports wood
Ex: Saudi Arabia: deserts, exports gasoline (imports grains)
Specialized Skills:
Areas become known for specific products (
