Study Notes
The Gravity Model of International Trade
- Predicts trade volume between countries based on their economic sizes and trade barriers.
- Formula: Tij = (Yi)a x (Yj)b / (Dij)c
- Tij = Trade volume between country i and j
- Yi = GDP of country i
- Yj = GDP of country j
- Dij = Trade impediments between country i and j
- a, b, c = Coefficients representing the importance of size and trade barriers
Factors Influencing Trade
- Size Matters: Larger economies produce and consume more, leading to greater trade volumes.
-
Trade Impediments:
- Distance: Increases transportation costs, impacting import & export.
- Cultural Affinity: Stronger cultural ties often correlate with stronger economic ties.
- Geography: Access to water, navigable rivers, and absence of barriers affect trade costs.
- Borders: Formal processes and tariffs raise trade costs.
- Trade Agreements: Reduce trade barriers and increase trade.
Globalization and Trade
- Reduced Distance Effect: Technological advancements have lowered distance-related costs, but distance still significantly influences trade.
- Political Factors: Wars, trade negotiations, and policy changes greatly impact trade.
-
Changing Composition of Trade: Shift from predominantly agricultural/mineral products to manufactured goods and services.
- Manufacturing goods now dominate, and service trade is increasing.
Recent Trade Developments
- Intermediate Goods Trade: More complex supply chains and increased international dependency.
- Service Outsourcing: Growing trade in services, driven by modern communication technology.
- International Production Networks: Countries specialize, increasing efficiency, and vulnerability.
Summary of International Trade
- Global trade is growing; developed economies still dominate trade, but developing nations are participating更多.
- The gravity model highlights the relationship between economic size and trade barriers and trade volume.
- Technological advancements have lowered distance barriers but not removed them.
- Political factors play a major role.
- Manufactured goods now dominate, but services are growing.
- Complex supply chains and international dependency are central to recent trade.
- Future service trade is likely to increase.
