The amount of reserves held by the US banking system reached $1.5 trillion in April 2011. Some economists argue that such a large quantity of bank reserves could lead to overly expansive bank lending as the economy recovers, regardless of the Federal Reserve's interest rate policy. In contrast,...

The quantity of reserves in the U.S. banking system has risen dramatically since September 2008. Some commentators have expressed concern that this pattern indicates that the Federal Reserve's liquidity facilities have been ineffective in promoting the flow of credit to firms and households....

We argue that the 2005 bankruptcy abuse reform (BAR) contributed to the surge in subprime foreclosures that followed its passage. Before BAR, over-indebted mortgagors could free up income to pay the mortgage by filing bankruptcy and having their unsecured debts discharged. BAR blocks that...

Banks hold liquid and illiquid assets. An illiquid bank that receives a liquidity shock sells assets to liquid banks in exchange for cash. We characterize the constrained efficient allocation as the solution to a planner's problem and show that the market equilibrium is constrained inefficient,...

Are companies with traded credit default swap (CDS) positions on their debt more likely to default? Using a proportional hazard model of bankruptcy and Merton's contingent claims approach, we estimate the probability of default for US nonfinancial firms. Our analysis does not generally find a...

Auto lenders were perhaps the biggest winners of the 2005 Bankruptcy Reform. Cars depreciate quickly, so borrowers often owe more than their car is worth. Prior to the Reform, these borrowers could reduce the principal on their auto loan to the market value of the car through a "cramdown" in...

We argue that the time-varying regional distribution of housing equity influences the aggregate consequences of monetary policy through its effects on mortgage refinancing. Using detailed loan-level data, we show that regional differences in housing equity affect refinancing and spending...

We use quasi-random access to the Home Affordable Refinance Program (HARP) to identify the causal effect of refinancing a mortgage on borrower balance sheet outcomes. We find that on average, refinancing into a lower-rate mortgage reduced borrowers' default rates on mortgages and nonmortgage...

The surge in credit and house prices that preceded the Great Recession was particularly pronounced in ZIP codes with a higher fraction of subprime borrowers (Mian and Sufi 2009). We present a simple model of prime and subprime borrowers distributed across geographic locations, which can...

In this paper, we argue that the observed difference in the cost of intraday and overnight liquidity is part of an optimal payments system design. In our environment, the interest charged on overnight liquidity affects output, while the cost of intraday liquidity only affects the distribution of...
