We model corporate liquidity policy and show that aggregate risk exposure is a key determinant of how firms choose between cash and bank credit lines. Banks create liquidity for firms by pooling their idiosyncratic risks. As a result, firms with high aggregate risk find it costly to get credit...

We suggest a new mechanism–the liquidity insurance channel–based on the widespread reliance of high credit quality firms on bank credit lines for liquidity management. Our model matches the patterns of usage of loans and credit lines in the cross-section of firms, and defines the conditions...

We examine the relation between the financial health of banks and their willingness to supply capital to borrowers under previously committed credit lines. We show that during the collapse of the Asset Backed Commercial Paper market in the last quarter of 2007 and the first half of 2008, banks...

We study how the consequences of violations of covenants associated with bank lines of credit to firms vary with the financial health of lenders. Following a violation banks restrict usage of lines of credit by raising spreads, shortening maturities, tightening covenants, or cancelling the line...

In this paper, we examine the relation between innovation and a firm's financial dependence using a sample of privately-held and publicly-traded U.S. firms. We find that public firms in external finance dependent industries spend more on R&D and generate a better patent portfolio than their...

We address the paradox that financial innovations aimed at risk-sharing appear to have made the world riskier. Financial innovations facilitate hedging idiosyncratic risks among agents; however, aggregate risks can be hedged only with liquid assets. When risk-sharing is primitive, agents...

We show that wrongful discharge laws - laws that inhibit the common-law doctrine of "employment-at-will" - spur innovation. In our model, wrongful discharge laws make it costly for firms to arbitrarily discharge employees. This enables firms to commit to not punish short-run failures of...
