international commerce

International trade involves economic transactions between countries, encompassing goods like consumer products, machinery, raw materials, and services. These transactions are facilitated by international financial payments, with private and central banks playing key roles. The primary goal of international trade is to acquire needed commodities and exchange surplus goods, ultimately aiming to improve a nation's standard of living.1

The field of international economics is divided into two main areas: the pure theory of international trade, which explains the benefits of trade and their distribution, and the theory of balance-of-payments adjustments, which examines foreign exchange markets and currency exchange rates. The Heckscher-Ohlin theory suggests that trade patterns are determined by a country's relative endowments of land, labor, and capital, meaning countries tend to export goods that utilize their abundant resources most effectively.2
