Three Common Reasons for Countries to Trade:
- Differences in Technology: Trade occurs when countries vary in their technological abilities, leading to advantageous trade based on the Ricardian model. For example, Japan's advanced technology in electronics allows it to export high-quality goods.
- Differences in Resource Endowments: Countries trade when their resource endowments differ, as seen in the Heckscher-Ohlin model. An example is Saudi Arabia exporting oil due to its rich natural resource endowment.
