Review Questions

• How does comparative advantage lead to increased efficiency in global trade?
  • Comparative advantage allows countries to specialize in producing goods where they have the lowest opportunity cost, leading to more efficient use of resources. By focusing on what they can produce best, nations can maximize their output and benefit from trading with others who specialize in different products. This efficiency not only boosts individual economies but also enhances overall global production and trade.
• Discuss the role of opportunity cost in determining a country's comparative advantage.
  • Opportunity cost plays a critical role in identifying a country's comparative advantage because it measures what must be given up to produce one good over another. A country has a comparative advantage in producing a good if it has a lower opportunity cost than its trading partners. Understanding these costs helps nations determine where to allocate resources most effectively, allowing for strategic specialization and beneficial trade relationships.
• Evaluate how changes in technology can impact comparative advantage and international trade dynamics.
  • Changes in technology can significantly alter comparative advantage by improving production methods or introducing new goods. For example, advancements in manufacturing technology may allow a country to produce certain goods more efficiently, shifting its comparative advantage in that area. As nations adapt to new technologies, the dynamics of international trade can change, leading to shifts in competitive positioning and potentially altering established trade agreements and relationships.
