Reputation bonds secure promises by forfeiting future profits. [definitional]
The typical diamond transaction involves the posting of a reputation bond equal to the present value of the profit on future transactions that will not take place if the promisor breaches a contract, less his ability to cover.
DEFINE: This is a formal economic/legal definition of how reputation functions as a bonding mechanism in diamond dealing.
