Transactions costs differ fundamentally from the conventional costs of neoclassical economics. At the proximate level, neoclassical costs arise from production activity or foregone consumption; they attach to different activity levels carried out in the context of well-specified rights. In contrast, transactions costs arise from the exchange and/or maintenance of the rights themselves (Eggertsson, 1995, p. 14); they are incurred to transfer the ownership andlor use status of the rights, and to monitor, enforce, or defend the rights. Both neoclassical costs and transactions costs ultimately derive from tastes, technology and resource endowments - the demand for transaction services, for example, is a derived demand based on the underlying preference structure of the economy - and both are measured with reference to a pre-existing resource utilization baseline.
