Lesson: International Economics (Grade 12 Level)
Hello to all my Grade 12 students! Welcome to the lesson on "International Economics." Many of you might think this topic feels distant and difficult due to all the technical jargon, but in reality, it’s the same concept as when you order products from overseas on a shopping app or see news headlines about the Thai Baht strengthening.
In this chapter, we will solve the mysteries: Why do countries trade with each other? How does a weak or strong Baht affect you? And what roles do global organizations play? If you’re ready, let’s get started! If it feels challenging at first, don't worry; we will go through it together step by step.
1. Why do we need international trade?
Just imagine: if we had to grow our own rice, weave our own fabric, produce our own smartphones, and refine our own oil all within one country, that would be impossible, right? This is the core reason why trade exists.
Key Reasons:
• Resource Differences: Some countries have abundant oil (e.g., the Middle East), while others have land perfect for agriculture (e.g., Thailand).
• Different Specializations: Some countries excel in technology (e.g., Japan, USA), while others are skilled in craftsmanship or services.
• Production Costs: Producing certain items domestically might be more expensive than simply buying them from neighbors.
Important Point: The principle you need to know is "The Principle of Advantage":
1. Absolute Advantage: When one country can produce a product more or better than another country.
2. Comparative Advantage: When a country chooses to produce the goods for which it has the lowest opportunity cost compared to producing other things. (This principle is the heartbeat of global trade.)
Summary of this section: Each country chooses to produce what they are best at and what has the lowest cost, then exchanges these goods so that everyone can enjoy higher-quality products at lower prices.
2. International Trade Policies
When trading, every country has its own "rules," which can be divided into two main categories:
A. Free Trade Policy
This allows trade to flow as easily as possible. It focuses on avoiding high tariffs and does not limit the volume of imports, ensuring fair competition.
B. Protectionism
This is when the government intervenes to "protect" domestic businesses so they can compete with foreign products, using tools such as:
• Tariffs: Imposing high taxes on imports so foreign goods become more expensive, encouraging people to buy domestic products.
• Quotas: Setting a limit on how much of a specific product can be imported in a given year.
• Subsidies: The government provides financial support to domestic producers so they can sell goods at lower prices to compete with foreign rivals.
Did you know? Even though free trade sounds ideal, countries sometimes use "protectionist policies" to help farmers or fledgling local businesses that are just starting out, so they don't go bankrupt.
3. Balance of Payments
Think of this as the "household account book" of a country, tracking how much money comes in and how much goes out.
The Balance of Payments is composed of major sub-balances:
1. Trade Balance: Looks only at merchandise exports and merchandise imports (tangible goods).
2. Service Balance: Tourism fees, transportation costs, and insurance premiums.
3. Current Account: The figure most frequently discussed because it combines the trade balance, service balance, and various other incomes. It is the key indicator of a country's economic strength.
Status of the Balance of Payments:
• Surplus: Money in > Money out (Getting wealthier).
• Deficit: Money out > Money in (Needs caution!).
• Balanced: Money in = Money out.
4. Foreign Exchange Rates
This is a frequent exam topic! It’s the comparison of the value of one country’s currency against another, such as $1 USD = 35 THB.
Appreciating vs. Depreciating Currency (Compared to the Dollar)
• Baht Appreciation (e.g., from 35 to 30 Baht): You need less Baht to buy the same amount of foreign goods.
Who benefits? -> Importers (foreign goods become cheaper), travelers going abroad, people with foreign debt.
Who loses? -> Exporters (they receive fewer Baht for their sales), Thai tour operators.
• Baht Depreciation (e.g., from 35 to 40 Baht): You need more Baht to buy the same amount of foreign goods.
Who benefits? -> Exporters (they exchange their earnings for more Baht), domestic tourism in Thailand.
Who loses? -> Importers (goods become more expensive), people buying fuel (because Thailand imports oil).
Memorization Trick:
"Strong-Import-Travel" (Appreciating currency - Importers gain - Travelers are happy).
"Weak-Export-Tour" (Depreciating currency - Exporters gain - Local tourism booms).
5. International Economic Cooperation
Countries group together to increase bargaining power and assist one another.
Regional Level:
• ASEAN: Focuses on cooperation in Southeast Asia, with AFTA as a free trade area.
• EU (European Union): Deep integration, even using the same currency (Euro).
• APEC: Cooperation among countries in the Asia-Pacific region (includes Thailand, USA, and China).
Global Level:
• WTO (World Trade Organization): Acts as a referee to resolve trade disputes and promote free trade.
• IMF (International Monetary Fund): A "pawn shop/bank" for countries facing financial crises to borrow money (like when Thailand borrowed from the IMF in 1997).
• World Bank: Focuses on long-term development loans, such as building roads or dams.
Common Mistake: Many people confuse the IMF with the World Bank.
Easy to remember: IMF = Help when you're sick (financial crisis); World Bank = Help when you're building a house (development).
Key points to remember before the exam!
1. Trade occurs because of differences in resources and costs.
2. Protectionist policies are used to help domestic producers, but excessive use can lead to retaliation from other countries.
3. A weaker Baht is good for exports and domestic tourism but makes imported fuel more expensive.
4. The Current Account is the primary indicator of whether the country is profitable or in the red regarding overall trade and services.
I hope this summary helps you understand International Economics better! It’s not as hard as it seems; just try to see the big picture of exchange. Keep it up, everyone! ✌️
