Economists frequently assume that financial markets satisfy a "no-arbitrage" condition. If one investment is much more profitable than another, people will buy that profitable investment until its price rises (or return falls) and it is no longer super-profitable. Is this a realistic assumption? Why or why not?

In economic terms, labour is the efforts exerted to produce any goods or services. It includes all types of human efforts – physical exertion, mental exercise, use of intellect, etc. done in exchange for an economic reward. Let us see the features of labour as a factor of production.

Explanation:

Resources required for generation of goods or services, generally classified into four major groups:

Land (including all natural resources),

Labor (including all human resources),

Capital (including all man-made resources), and.

Enterprise (which brings all the previous resources together for production).
