A Credit Mechanism For Selecting A Unique Competitive Equilibrium, Cheng-Zhong Qin, Martin Shubik Nov 2005

A Credit Mechanism For Selecting A Unique Competitive Equilibrium, Cheng-Zhong Qin, Martin Shubik

Cowles Foundation Discussion Papers

The enlargement of the general-equilibrium structure to allow default subject to penalties to appririate 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 limmits and default penalties for a 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 …

Changes in total surplus and deadweight loss are traditional measures of economic welfare. We propose necessary and sufficient conditions for rationalizing consumer demand data with a quasilinear utility function. Under these conditions, consumer surplus is a valid measure of consumer welfare. For nonmarketed goods, we propose necessary and sufficient conditions on market data for efficient production , i.e., production at minimum cost. Under these conditions we derive a cost function for the nonmarketed good, where producer surplus is the area above the marginal cost curve.
