When limited commitment hinders unsecured credit, assets help by serving as collateral. We study models where assets differ in pledgability - the extent to which they can be used to secure loans - and hence liquidity. Although many previous analyses of imperfect credit focus on producers, we...

I examine the impact of alternative monetary policy rules on a rational asset price bubble, through the lens of an overlapping generations model with nominal rigidities. A systematic increase in interest rates in response to a growing bubble is shown to enhance the fluctuations in the latter,...

The U.S. Federal Reserve used the Term Auction Facility (TAF) to provide term funding to eligible depository institutions from December 2007 to March 2010. According to the Fed, the purpose of TAF was to inject term funds through a broader range of counterparties and against a broader range of...

Our paper explores a transmission mechanism of monetary policy through bond market. Based on the assumption of delayed responses of economic agents to monetary shocks, we derive a system of equations relating the term structure of interest rates with the past history of money growth rates and...

The paper reconsiders the role of money and banking in monetary policy analysis by including a banking sector and money in an optimizing model otherwise of a standard type. The model is implemented quantitatively, with a calibration based on U.S. data. It is reasonably successful in providing an...

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....

This paper examines macroprudential policies in open emerging economies. It discusses how the recent financial crisis has provided a rationale for macroprudential policies to help manage the economy and the need for policymakers to monitor the financial cycle and systemic risks. It also...

We document that the percentage of all U.S. assets that are "safe" has remained stable at about 33 percent since 1952. This stable ratio is a rare example of calm in a rapidly changing financial world. Over the same time period, the ratio of U.S. assets to GDP has increased by a factor of 2.5,...

This article explains how debt markets have malfunctioned in the crisis, with deleterious consequences for the real economy. I begin with a quick overview of debt markets. I then discuss three areas that are crucial in all debt markets decisions: risk capital and risk aversion, repo financing...

We present evidence that high concentration in local mortgage lending reduces the sensitivity of mortgage rates and refinancing activity to mortgage-backed security (MBS) yields. A decrease in MBS yields is typically associated with greater refinancing activity and lower rates on new mortgages....
