  Despite efforts to increase the supply of organs from living donors, most
kidney transplants performed in Australia still come from deceased donors. The
age of these donated organs has increased substantially in recent decades as
the rate of fatal accidents on roads has fallen. The Organ and Tissue Authority
in Australia is therefore looking to design a new mechanism that better matches
the age of the organ to the age of the patient. I discuss the design,
axiomatics and performance of several candidate mechanisms that respect the
special online nature of this fair division problem.
