In reading the Wikipedia article about the "financial accelerator," I read this
Firms’ ability to borrow depends essentially on the market value of their net worth. The reason for this is the familiar story of asymmetric information between lenders and borrowers. Lenders are likely to have little information about the reliability of any given borrower. As such, they usually require borrowers to set forth their ability to repay, often in the form of collateralized assets.
So, I believe that models with a financial accelerator, such as Kiyotaki and Moore (1997), assume a credit constraint. I am looking form papers that derive these credit constraints. That is, where do they come from? Could someone provide the reference?
Papers that I can think of are, for example, Hart and Moore (1994), which derives constraints that are driven by asymmetric information and the inalienability of human capital, or Myers and Rajan (1998), which derives debt capacity from inefficient liquidation and the ability of the manager to engage in asset substitution. What are the classic papers on this topic?
