A CREDIT MECHANISM FOR SELECTING A UNIQUE COMPETITIVE EQUILIBRIUM By

The enlargement of the general-equilibrium structure to allow for default subject to appropriate credit limits and default penalties results in a construction of a simple mechanism for a credit using society. We show that there generically exists a price-normalizing bundle that determines a credit money along with appropriate credit limits and default penalties for the credit mechanism to select a unique competitive equilibrium (CE). With some additional conditions, a common credit money can be applied such that any CE can be a unique selection by the credit mechanism with appropriate credit limits default penalties for the traders. This will include a CE with the minimal cash flow property. Such CEs are special for the reason that they minimize the need for a substitute-for-trust (i.e. money) in trade.
