Finance and economic development in a model with credit rationing

This paper develops a simple model with credit rationing and endogenous default risk in which the expectation of a bailout may lead to a financial sector which is too large with respect to the the social optimum. The paper concludes with a short discussion of how this model could be used as a building block for models aimed at endogenizing the probability of a bailout, and discussing the relationship between the size of the finanancial sector and economic growth in the presence of default risk.
