Please clarify your question.
People engage in trade mostly in order to exchange goods and services they have for the ones they need or desire. Trade allows individuals and businesses to specialize in producing specific goods or services they are most efficient at, and then trade those products with others who specialize in different areas. By engaging in trade, people can access a wider variety of goods and services, increase their standard of living, and foster economic growth.
To understand why people engage in trade, we can look at the concept of comparative advantage. Comparative advantage refers to the ability of an individual, business, or country to produce a particular good or service at a lower opportunity cost than others. Opportunity cost is the value of an alternative choice or option that is given up when a decision is made.
For example, let's consider two individuals, Amy and Bob. Amy can produce 10 shirts or 5 pairs of jeans in one day, while Bob can produce 8 shirts or 4 pairs of jeans in the same timeframe. Amy has an absolute advantage in both shirt and jeans production because she can produce more of each item. However, if we compare their opportunity costs, we see that Amy's opportunity cost of producing one shirt is 0.5 pairs of jeans, while Bob's opportunity cost of producing one shirt is 0.5 pairs of jeans as well. This means that Bob has a comparative advantage in producing shirts because he gives up fewer pairs of jeans to produce one.
Based on their comparative advantage, Amy and Bob can specialize in producing the good they are more efficient at. Amy can focus on producing shirts, while Bob can focus on producing jeans. Then, they can trade their products with each other. By doing so, both Amy and Bob can benefit from the trade. Amy gets access to jeans, which she can acquire at a lower opportunity cost by trading with Bob than if she were to produce them herself. Bob, on the other hand, gets shirts without having to incur the higher opportunity cost of producing them himself.
This concept of comparative advantage applies not only to individuals but also to businesses and countries. By specializing in what they are relatively better at producing, entities can trade with others to obtain goods and services that they are less efficient in producing. Through trade, resources are allocated more efficiently, improving overall productivity and economic welfare.
