Final answer:
The primary reason for international trade is not just a lack of natural resources; it includes factors like comparative advantage and economies of scale. While larger economies like the U.S. have less need, they still engage in international trade for various benefits.
Step-by-step explanation:
The statement that the primary reason for international trade is a lack of natural resources in developed nations is false. International trade is motivated by a variety of factors including increasing economic efficiency, gaining access to goods and services that are not available domestically, and benefiting from comparative advantage and economies of scale. Low-income countries often benefit more from trade than high-income countries because their smaller economies allow limited opportunities for internal trade and less competition among firms, which can result in higher prices and less diversity in goods for consumers.
On the other hand, high-income and large economic countries like the United States can derive significant benefits from internal trade within their vast economies. However, despite its size, the U.S. still engages in international trade to increase variety for consumers, acquire resources and services more efficiently, and enhance its economic strength through strategic trade agreements.
