Global firms are companies that operate in multiple countries around the world. They engage in international trade, producing goods and services that cater to diverse markets. These firms often have a centralized headquarters but maintain branches or subsidiaries in various locations to manage local operations and adapt to regional demands. These companies benefit from economies of scale, allowing them to reduce costs and increase efficiency. By leveraging global supply chains, they can source materials and labor from different countries. Examples of global firms include Apple, Coca-Cola, and Toyota, which have established a strong presence in numerous international markets.
