We construct a synthesized model to study credit rationing by loan size. In our model, the borrower faces a trade-off between raising debt and exerting costly effort to undertake an investment project. In the absence of agency costs, increasing the loan size at the equilibrium interest rate...

We reexamine Stiglitz Weiss (1981) credit rationing by simultaneously considering adverse selection and moral hazard. If returns of the projects are ranked by first-order stochastic dominance, neither adverse selection nor moral hazard exists. If the projects have equalized expected returns,...

With a more general setting, we illustrate that credit rationing in the Stiglitz and Weiss (1981) model is sensitive to the ranking of projects. Given that the ranking is according to the mean-preserving-spread, adverse selection and moral hazard cannot co-exist and credit rationing occurs only...
