There is a demand for safe assets, either government bonds or private substitutes, for use as collateral. Government bonds are safe assets, given the government's power to tax, but their supply is driven by fiscal considerations, and does not necessarily meet the private demand for safe assets....

Economic growth involves metamorphosis of the financial system. Forms of banks and bank money change. These changes, if not addressed, leave the banking system vulnerable to crisis. There is no greater challenge in economics than to understand and prevent financial crises. The financial crisis...

We survey the literature on securitization and lay out a research program for its open questions. Securitization is the process by which loans, previously held to maturity on the balance sheets of financial intermediaries, are sold in capital markets. Securitization has grown from a small amount...

Private information about prospective borrowers produced by a bank can affect rival lenders due to a "winner%u2019s curse" effect. Strategic interaction between banks with respect to the intensity of costly information production results in endogenous credit cycles, periodic "credit crunches."...

Short-term collateralized debt, such as demand deposits and money market instruments - private money, is efficient if agents are willing to lend without producing costly information about the collateral backing the debt. When the economy relies on such informationally-insensitive debt, firms...

All bond prices plummeted (spreads rose) during the financial crisis, not just the prices of subprime- related bonds. These price declines were due to a banking panic in which institutional investors and firms refused to renew sale and repurchase agreements (repo) - short-term, collateralized,...

The savings/investment process in capitalist economies is organized around bank-like financial intermediaries (“banks”), making them a central institution of economic growth. These intermediaries borrow from consumer/savers and lend to companies that need resources for investment. In...

The equity and debt prices of large nonbank firms contain information about the future state of the banking system. In this sense, banks are informationally central. The amount of this information varies over time and over equity and debt. During a financial crisis banks are, by definition of a...
