MODULE 1: INTRODUCTION TO INTERNATIONAL TRADE
🔹 Meaning of International Economics (Concept)
International economics studies how countries interact through trade of goods and services. It
explains how exports and imports affect national economies.
Exports are goods and services sold to other countries, while imports are those purchased from
abroad. These flows determine trade balances and economic relations.
The subject also studies policies affecting trade and international payments. It connects domestic
markets with the global economy.
🔹 Pattern of Trade
The pattern of trade refers to what goods countries export and import. It depends on differences in
resources, technology, and preferences.
Countries specialize in producing goods where they have efficiency advantages. This leads to exchange
of goods between nations.
Trade patterns are influenced by comparative advantage and factor endowments. They change over
time with economic development.
Understanding trade patterns helps explain global production and consumption. It shows how
countries are interconnected.
🔹 Gains from Trade
Gains from trade arise when countries specialize and exchange goods. This leads to more efficient use
of resources.
Consumers benefit from lower prices and greater variety of goods. Producers gain access to larger
markets.
Trade increases overall economic welfare in participating countries. It allows consumption beyond
production possibilities.
Both countries benefit even if one is more efficient in all goods. Comparative advantage ensures
mutual gains.
🔹 Migration (Concept)
Migration refers to the movement of people from one country to another. It occurs for economic,
social, or political reasons.
It affects labor supply in both home and host countries. This influences wages and employment levels.
,Migration can lead to gains in global output. However, it also creates distributional effects.
🔹 Types of Migration
🔸 Economic Migration
Economic migration occurs when people move to find better job opportunities. It is driven by wage
differences between countries.
Workers move from low-income to high-income countries. This increases global efficiency of labor
allocation.
Host countries benefit from increased labor supply. Home countries may face loss of skilled workers.
Overall, migration leads to higher global production. However, effects vary across groups.
🔸 Political Migration
Political migration occurs due to war, conflict, or persecution. People move to seek safety and
stability.
Refugees and asylum seekers are common examples. Their movement is often forced rather than
voluntary.
Host countries may face economic and social challenges. However, migrants can contribute to the
economy over time.
Political migration is influenced by global conditions. It requires international cooperation.
🔹 Foreign Direct Investment (Concept)
Foreign Direct Investment (FDI) involves investment in production facilities abroad. Firms gain control
over foreign operations.
It allows firms to expand globally and access new markets. It is a key feature of globalization.
FDI promotes technology transfer and economic development. It links economies through capital flows.
🔹 Types of FDI
🔸 Horizontal FDI
Horizontal FDI occurs when firms produce the same goods in different countries. It is used to serve
local markets directly.
Firms avoid trade costs by producing close to consumers. This improves efficiency in distribution.
It is common among developed countries with similar markets. Market access is the main motive.
, Horizontal FDI increases competition and consumer choice. It strengthens global production networks.
🔸 Vertical FDI
Vertical FDI occurs when firms split production across countries. Different stages of production are
located in different places.
It is driven by cost differences such as wages and resources. Firms locate stages where costs are
lowest.
It leads to global supply chains and specialization. Efficiency improves through division of labor.
Vertical FDI increases trade in intermediate goods. It connects countries through production processes.
🔹 Reasons for Trade
🔸 Proximity
Countries trade more with nearby nations due to lower transport costs. Distance affects the volume
of trade.
Cultural and historical ties also influence trade patterns. Neighboring countries often have strong
trade links.
Proximity reduces information and transaction costs. This makes trade easier and more efficient.
It is an important factor in the gravity model of trade. Closer countries tend to trade more.
🔸 Resources
Countries differ in natural and human resources. These differences create opportunities for trade.
Resource-rich countries export goods that use their abundant resources. Others import these goods.
Trade allows efficient allocation of global resources. It increases overall productivity.
Resource differences are a key reason for comparative advantage. They shape global trade patterns.
🔸 Absolute Advantage (Concept)
Absolute advantage occurs when a country can produce a good with fewer resources. It is based on
productivity differences.
Countries specialize in goods where they are more efficient. This increases total output.
Trade based on absolute advantage improves efficiency. However, it does not explain all trade
patterns.
🔸 Comparative Advantage (Concept)
