Safe assets play a critical role in an(y) economy. A "safe asset" is an asset that is (almost always) valued at face value without expensive and prolonged analysis. That is, by design there is no benefit to producing (private) information about its value. And this is common knowledge....

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...

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,...

Why did the failure of Lehman Brothers make the financial crisis dramatically worse? The financial crisis was a process of a build-up of risk during the crisis prior to the Lehman failure. Market participants tried to preserve an option or exit by shortening maturities - the "flight from...
