In economics, what idea explains that land, labour, and capital limit the supply of what people want and need?

• A. Economy
• B. Scarcity
• C. Public good
• D. Privately owned

Answer: (B)

Scarcity means there aren’t enough resources to satisfy all the wants and needs people have. The idea that land, labour, and capital limit the supply of goods and services is scarcity in action: these are the resources used to produce everything we buy, so when they are limited, what can be produced is also limited. Because resources are finite, producers must decide what to make, how to make it, and who gets the products, which is why supplies aren’t unlimited and prices can rise when demand is high. Land refers to natural resources, labour to the effort people contribute, and capital to the tools, machines, and buildings used in production. This explains why the availability of goods and services is restricted.

An economy is a system for organizing production and distribution, not the reason supplies are limited. A public good is a type of good with non-excludability and non-rivalry, not the reason supplies are constrained. Privately owned describes ownership, not the limiting idea behind why resources cap production.
