What is the relationship between International trade and welfare?

International trade can enhance welfare by providing access to a broader range of goods and services, often at lower prices due to competition and economies of scale. It allows countries to specialize in the production of goods where they have a comparative advantage, leading to more efficient resource allocation. Additionally, trade can stimulate economic growth, create jobs, and improve overall living standards. However, the benefits may not be evenly distributed, leading to potential disparities within and between countries.
