WebMar 26, 2024 · The Fisher's separation theorem is an economic theory that states that the investment choices or decisions of a firm are independent of the investment preferences of the firms owners. This theorem postulates that a firm should be concerned about maximizing profit rather than trying to achieve the diverging objectives of the firms owners.
