Why might a country choose to specialize in a certain good and trade for others?

A country may specialize in a good that it can produce most efficiently, so it uses its resources—like skilled workers or good technology—to make that good better than other countries. By focusing on this product, the country saves time and money, making the good cheaper and higher quality. It can then trade the surplus to other nations that need that good, while buying goods it cannot produce as well. For example, Japan focuses on high‑tech cars and trades them for coffee beans that it cannot grow cheaply. This way, everyone gets more goods than they could produce alone.
