Trade is the voluntary exchange of goods or services for mutual benefit. It is a key part of a global economy and fosters international cooperation. Trade can range from the sale of baseball cards between collectors to multimillion dollar contracts between companies. International trade links countries to the global marketplace, increasing efficiency and fostering connections that boost economic growth. Countries can also benefit from foreign direct investment (FDI), which brings currency and expertise. However, some economists argue that free trade can make a country too dependent on the global market and support protectionism to nurture developing industries.
The Industrial Revolution in the 1700s led to advances in manufacturing, and people started trading commodities on a regular basis. This increased the availability of certain products and gave rise to a philosophy called laissez-faire capitalism, or “let the market decide.” Many wealthy people used this approach, which emphasized that governments should not interfere with businesses and trade. But some people argued that businesses might pay workers poorly and pollute the environment, so they wanted to put limits on business practices.
The Law of Comparative Advantage explains that each country is endowed with different natural resources and assets, which means some countries can produce some goods more efficiently than others. This allows them to trade for goods that they cannot produce themselves, and helps to lower prices for consumers. However, many countries try to shield their local industry by imposing tariffs and trade barriers, which reduces the benefits of free trade.
