International Trade

1) Hook — A Fun Real-Life Story

Imagine you are in a local market in India looking to buy a smartphone. The phone is designed in California, assembled in China, uses chips from Taiwan, and software developed in India. This simple purchase is a perfect example of international trade—countries exchanging goods and services to benefit from each other's strengths. Just like this phone, countries trade to get what they need or want, often at better prices or quality than if they tried to produce everything themselves.

2) Core Concepts of International Trade

International Trade refers to the exchange of goods and services between countries. It allows nations to specialize based on their advantages, leading to increased efficiency and wealth.

• Absolute Advantage: When a country can produce a good using fewer resources than another.
• Comparative Advantage: When a country produces a good at a lower opportunity cost than another.
• Terms of Trade (ToT): The rate at which goods from one country exchange for goods from another.

Example: Consider India and Bangladesh producing textiles and jute.

Interpretation:

• India has an absolute advantage in both textiles and jute (higher units/hour).
• To find comparative advantage, calculate opportunity cost:

Conclusion: India has a lower opportunity cost in textiles (0.5 < 0.67), so it should specialize in textiles. Bangladesh has a lower opportunity cost in jute (1.5 < 2), so it should specialize in jute. Both countries benefit by trading.
