When parties are very unequally endowed, agreement may be very difficult to
reach, even if the specific transaction is easy to contract on, and fungib
le resources can be transferred to compensate the losing party. The very fu
ngibility of the resource transferred makes it hard to restrict its use, ch
anging the amount the parties involved spend in trying to grab future rents
. This spill-over effect can inhibit otherwise valuable transactions, as we
ll as enable otherwise inefficient transactions. Agreement typically breaks
down when the required transfer is large and the proposed recipient of the
transfer is relatively unproductive or poorly endowed. We examine the impl
ications of this model for a theory of the optimal allocation of property r
ights. (C) 2000 Elsevier Science S.A. All rights reserved.
