Research Abstract |
1. We assume two types of borrowers with different repayment probability. If a bank can not distinguish these borrowers (NDB), she must decide the terms of loan under incomplete information. We show that an equilibrium can exist under the appropriate values of the parameters and calculate the bank's profit in that case. We also calculate the profit under the same parameter values when the bank can distinguish two types of borrowers (DB). We find that social welfare is larger in DB than in NDB. This result suggests that banks have incentive to enter into the alliance with a non-bank. 2. We assume that the financial institutions are different in cost structure and investigate the LREq. We derive the number of firms in the long-run Cournot equilibrium and compare it with that of the second best equilibrium in which social welfare is maximized. We prove that the EET holds in the long-run even if firms have different cost structures. 3. There exists the Financial Market that the monopoly private financial institution supplies finances oligopolies consumer financial serves (CFS). The LREq is the break even point of the down stream firm. The number of CFS in LREq is less than the number of second best. 4. The monopoly public financial institution supplies finance to CFS in the down stream market. The number of CFS in the LREq is excessive. 5. Small business companies can borrow from either banks or non-banks. We show that the companies borrow from banks in equilibrium but social welfare becomes larger when borrowing from non-banks and defines a meaningful of the existing for non-banks under the welfare. 6. We analyzed problem of EET and Imperfect Information by focusing on were the Second-Best Social Welfare, Contestable Market Equilibrium and Free Entry Equilibrium.
