What describes the basic principle of supply and demand without international trade?

• A. It only applies to agricultural products
• B. It illustrates static market conditions
• C. It showcases a closed economy model
• D. It is irrelevant in modern economics

Answer: (C)

The basic principle of supply and demand describes the relationship between the availability of a product or service (supply) and the desire for that product or service (demand) under normal market conditions. When considering this principle in the context of a closed economy—where there is no international trade—the focus is solely on domestic production and consumption. In a closed economy, the dynamics of supply and demand determine the prices and quantities of goods and services sold within that economy without the influence of external markets. This model helps in understanding how changes in supply (such as production increases or declines) or demand (like consumer preferences) can affect market equilibrium—the point at which quantity supplied equals quantity demanded. The other options do not accurately describe this principle under the specified conditions. The assertion that it only applies to agricultural products limits the scope of supply and demand, which is a universal economic concept relevant to all goods and services. Describing the principle as illustrating static market conditions overlooks the essential dynamics and fluctuations inherent in supply and demand interactions. Lastly, the claim that the principle is irrelevant in modern economics disregards its foundational importance in understanding market behavior, regardless of the existence of international trade.
