This Article proposes a new mechanism for valuing firms in bankruptcy. Unde
r the "senior dilution" mechanism, a court would dilute the reorganized sto
ck issued to senior claimants by issuing additional shares to junior claima
nts until there was no excess demand for the stock at a price that would im
plement absolute priority. A "junior dilution" mechanism could also be impl
emented to provide a market test for proposed reorganization plans of junio
r claimants by having a court issue additional debt to senior claimants unt
il there was no excess supply of the debt at a price that would implement a
bsolute priority. We show that these mechanisms harness the private informa
tion of the claimants and of third parties to produce distributions consist
ent with absolute priority. Dilution mechanisms can be superior to other in
formation-harnessing devices (such as an option or auction approach) becaus
e they (1) are less susceptible to the problem of junior illiquidity l than
an option approach proposed by Lucian Bebchuk; (2) are less susceptible to
the problem of market manipulation and may better allocate control premia
than a partial float proposal by Mark Roe; and (3) may produce fewer transa
ction costs than a full auction approach proposed by Douglas Baird. Moreove
r, as a response to the Supreme Court's recent admonishment in LaSalle that
bankruptcy courts employ market tests more often when creditors dissent to
a reorganization plan, the junior dilution mechanism provides a uniquely w
orkable solution within the current statutory framework.
