Which of the following do economists consider to be capital?
a share of IBM stock
a savings account
a pair of stockings
a construction crane
The Correct Answer and Explanation is:
The correct answer is: a construction crane
Explanation:
In economics, capital is one of the four fundamental factors of production, along with land, labor, and entrepreneurship. Economists define capital specifically as man-made goods that are used to produce other goods and services. This includes tools, machinery, buildings, equipment, and technology used in the production process.
A construction crane is a quintessential example of capital in the economic sense. It is a physical, durable asset created by humans to assist in the production of structures and infrastructure. The crane does not produce goods or services for immediate consumption; rather, it enables construction firms to increase productivity, reduce labor demands, and build larger and more complex structures efficiently. Thus, it is classified as physical capital, more precisely, fixed capital because it is used repeatedly in the production process over time.
Let us contrast this with the other choices:
- A share of IBM stock represents ownership in a company and potentially a claim on future profits (dividends). While it is a financial asset, it is not capital in the economic sense because it is not directly used in the production of goods and services. Financial capital facilitates investment but is conceptually distinct from physical capital.
- A savings account is also a form of financial capital or wealth storage. Although savings may be used to fund investment (e.g., loans for business purchases), the account itself is not a productive asset.
- A pair of stockings is a consumer good, meant for final consumption, not for production. It does not contribute to the production of other goods or services.
Therefore, economists reserve the term “capital” for tangible, productive assets like machinery, tools, and buildings—making the construction crane the only appropriate choice.
