I had an introductory class in marketing last week, and the professor wanted to test our previous knowledge of economics (we are juniors). He asked us this simple question: "What are the fundamental/basic categories in economics?"
Confused by the vagueness of the question, most of us said labor, capital, profit, markets... All sorts of things, but none were apparently correct. In the end, he said that the correct answer is:
- result (as in profit or revenue)
He continued to say that we define everything in economics on the basis of these three categories.
My questions now are: is this true? Do I really have such a significant knowledge gap that I somehow missed this crucial piece? Where can I find the confirmation of his statement?
If this is not true, can you please refer me to where I can find the answer to this question?
