Using proprietary balance sheet data for Korean banks and a simultaneous equation model, we document that increased marginal funding costs lead to larger solvency risk (as measured by the Tier 1 regulatory capital ratio), which, in turn, leads to larger marginal funding costs. A 100 bp increase...

We assess the empirical validity of the trilemma or impossible trinity in the 2000s for a large sample of advanced and emerging market economies. To do so, we estimate Taylor rule-type monetary policy reaction functions, relating the local policy rate to real-time forecasts of domestic...

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...

The global financial crisis has shaken the foundations of the deceptively comfortable pre-crisis central banking world. Central banks face a threefold challenge: economic, intellectual and institutional. This essay puts forward a compass to help central banks sail in the largely uncharted waters...

The recent financial crisis has triggered a major rethink of analytical approaches and policy towards financial stability. The crisis has encouraged a sharper focus on systemic risk, the inclusion of a financial sector in macroeconomic models, a shift from a microprudential to a macroprudential...
