The 'Fisher separation theorem' in economics asserts that the objective of a will be the maximization of its present value, regardless of the preferences of its owners. The theorem therefore separates management's "productive opportunities" from the entrepreneur's "market opportunities". It was proposed by – and is named after – the economist Irving Fisher.

The Fisher Separation Theorem states that:

★ the firm's investment decision is independent of the preferences of the owner;

★ the investment decision is independent of the financing decision.

★ the value of a capital project (investment) is independent of the mix of methods – equity, debt, and/or cash – used to finance the project.

Fisher showed the above as follows:
#The firm can make the investment decision — i.e. the choice between productive opportunities — that maximizes its present value, independent of its owner's investment preferences.
#The firm can ''then'' ensure that the owner achieves his optimal position in terms of "market opportunities" by funding its investment either with borrowed funds, or internally as appropriate.
