Big markets need cheap info intermediaries to sustain reputation-based contracts [causal]
Charny has noted, however, that a reputation-bond-based, extralegal contractual regime will function even in large scale markets so long as "technology . . . such as computers used to monitor credit worthiness, or mass media used in advertising, [make it possible to] convey information cheaply to a large group of transactors . . . [that is] when a thick set of informational intermediaries" exists.
DEFINE: Clarifies the condition under which extralegal contractual regimes can scale to large markets: the presence of informational intermediaries that cheaply convey trustworthiness data.
