We document a steady decline in the share of secured debt issued (as a fraction of total debt) in the United States over the twentieth century, with some pickup in this century. Superimposed on this secular trend, the share of secured debt issued is countercyclical. The secular decline in...

"Using a comprehensive database of firms in Western and Eastern Europe, we study how the business environment in a country drives the creation of new firms. Our focus is on regulations governing entry. We find entry regulations hamper entry, especially in industries that naturally should have...

We show in this paper that bank failures can be contagious. Unlike earlier work where contagion stems from depositor panics or ex ante contractual links between banks, we argue bank failures can shrink the common pool of liquidity, creating or exacerbating aggregate liquidity shortages. This...

We explore the connection between money, banks, and aggregate credit. We start with a simple real' model without money, where banks make loans repayable in goods and depositors hold claims on the bank payable on demand in goods. Aggregate production may be delayed in the economy. If so, we show...

We examine how competition amongst lenders exacerbates risk taking during a boom using a simple proxy for the risk of a bank's loan portfolio--the average physical distance of borrowers from banks' branches. The evolution of lending distances is cyclical, lengthening considerably during an...

Do low interest rates alleviate banking fragility? Banks finance illiquid assets with demandable deposits, which discipline bankers but expose them to damaging runs. Authorities may choose to bail out banks being run. Unconstrained bailouts undermine the disciplinary role of deposits. Moreover,...

The cheapest way for banks to finance long term illiquid projects is typically to borrow short term from households. But when household needs for funds are high, interest rates will rise sharply, debtors will have to shut down illiquid projects, and in extremis, will face more damaging runs....

Is there any need to "clean" up a banking system in the midst of a crisis, by closing or recapitalizing weak banks and taking bad assets off bank balance sheets, or can one wait till the crisis is over? We argue that an "overhang" of impaired banks that may be forced to sell assets soon can...

What caused the financial crisis that is sweeping across the world? What keeps asset prices and lending depressed? What can be done to remedy matters? While it is too early to arrive at definite answers to these questions, it is certainly time to offer informed conjectures, and these are the...

Banks can fail either because they are insolvent or because an aggregate shortage of liquidity can render them insolvent. We show that bank failures can themselves cause liquidity shortages. The failure of some banks can then lead to a cascade of failures and a possible total meltdown of the...
