The   Modigliani-Miller Theorem at 60:


The Long-Overlooked Legal Applications of
Finance's Foundational Theorem



Michael  S. Knollt

     2018  marks   the sixtieth anniversary of the publication  of Franco
Modigliani andMerton  Miller's The Cost of Capital, Corporation Finance, and
the Theory ofInvestment, which purports to demonstrate that a firm 's value is
independent of its capital structure. Widely hailed as the foundation of modern
finance, their article is little known by lawyers and legal academics even though
it led to many major economic advances, such as agency costs and asymmetric
information, recognized  and  used  throughout  the law  today. The  legal
profession's lack offamiliarity with these Nobel Prize-winning authors and their
work  is not merely an oversight; it is a missed opportunity. When inverted, the
Modigliani-Miller theorem  describes the mechanisms  through which  capital
structure can affect value. This reverse Modigliani-Miller theorem provides a
powerfulframework   that can be extremely useful to legal academics, practicing
attorneys, and judges.
