Comparative advantage is an economic concept that states that countries and businesses can benefit from trading with one another by producing or obtaining goods where they are most efficient or effective. With this concept, both countries involved in the trade can gain a competitive advantage by specializing in certain goods, then trading those goods with each other. In essence, it allows countries to do what they do best and import everything else, resulting in maximum efficiency and profit. Comparative advantage enables businesses to expand their markets, lower their costs, increase production, increase profits, and grow more quickly. It’s no wonder why so many businesses strive for it!
