The 30-year U.S. swap spreads have been negative since September 2008. We offer a novel explanation for this persistent anomaly. Through an illustrative model, we show that underfunded pension plans optimally use swaps for duration hedging. Combined with dealer banks' balance sheet constraints,...

This paper surveys the theoretical and empirical literature on the macroeconomic implications of financial imperfections. It focuses on two major channels through which financial imperfections can affect macroeconomic outcomes. The first channel, which operates through the demand side of finance...

This paper surveys the literature on the linkages between asset prices and macroeconomic outcomes. It focuses on three major questions. First, what are the basic theoretical linkages between asset prices and macroeconomic outcomes? Second, what is the empirical evidence supporting these...

I explain the key failure mechanics of large dealer banks, and some policy implications. This is not a review of the financial crisis of 2007-2009. Systemic risk is considered only in passing. Both the financial crisis and the systemic importance of large dealer banks are nevertheless obvious...

The quality of newly originated subprime mortgages had been visibly deteriorating for some time before the window for such loans was shut in 2007. Nevertheless, a bankruptcy court's directed ex post examination of New Century Financial, one of the largest originators of subprime mortgages,...

What are liquidity crises? And what can be done to address them? This short paper brings together some personal reflections on this issue, largely based on previous work. In the process, it questions a number of commonly held beliefs that have become part of the conventional wisdom. The paper is...

Over the last decade or so, addressing financial instability has become a policy priority. Despite the efforts made, policymakers are still a long way from developing a satisfactory operational framework. A major challenge complicating this task is the "fuzziness" with which financial...

It is high time we rediscovered the role of the financial cycle in macroeconomics. In the environment that has prevailed for at least three decades now, it is not possible to understand business fluctuations and the corresponding analytical and policy challenges without understanding the...

We critically review the state of the art in macro stress testing, assessing its strengths and weaknesses. We argue that, given current technology, macro stress tests are ill-suited as early warning devices, ie as tools for identifying vulnerabilities during seemingly tranquil times and for...

The existing literature on estimated structural News Driven Business Cycle (NDBC) models has focused almost exclusively on macroeconomic data and has largely ignored asset prices. In this paper, we present evidence that including data on asset prices in the estimation of a structural NDBC model...
