Analysis of credit rationing in commodity, money and bond Markets; by the use of walras's law

One of the most important issues in financial market particularly for banks is the issue of asymmetric information. Adverse selection could be made from the lack of sufficient information about credit specification, type of preferences and in general, rate of risk taken by borrowers. In this situation average cost of loan repayment will be of interest for the banking system. It will increase interest rate in order to have a lower rate of average cost. So those who take low level of credit risk are not interested in borrowing. And as a result we have a decline in borrower's rate with lower rate of credit risk. Therefore an increase in the interest rate also increases the possibility of adverse selection. As a result they specify interest rate ceiling with lower rate of interest at equilibrium point (over demand in loan market) and because of loan over demand and market clearing, loans and credits are being rationed. In this article credit rationing and its effect on money market, bond market and commodity market will be analyzed by walras’s law. It can be shown that in credit rationing, the walras’s law does not hold in an effective market unless and until we consider monetary dimension of bond market (credit market) in the model.
