We study a test statistic based on the integrated squared difference between a kernel estimator of the copula density and a kernel smoothed estimator of the parametric copula density. We show for fixed smoothing parameters that the test is consistent and that the asymptotic properties are driven...

One of the most enduring questions in finance is the persistence of investment risk across time. Traditional finance lacks of recipes on how to approach and how to hedge non-diversifiable risks. Risks that can not be diversified at a given point in time can nevertheless be averaged over time...

We consider a nonparametric method to estimate copulas, i.e. functions linking joint distributions to their univariate margins. We derive the asymptotic properties of kernel estimators of copulas and their derivatives in the context of a multivariate stationary process satisfactory strong mixing...

The 2007-2008 financial crises has made it painfully obvious that markets may quickly turn illiquid.Moreover, recent experience has shown that distress and lack of active trading can jump “around”between seemingly unconnected parts of the financial system contributing to transforming...

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...

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...

In this paper, we identify and document the empirical characteristics of the key drivers ofconvertible arbitrage as a strategy and how they impact the performance of convertible arbitragehedge funds. We show that the returns of a buy-and-hedge strategy involving taking a longposition in...

This paper studies the “confidential holdings” of institutional investors, especially hedge funds, where thequarter-end equity holdings are disclosed with a significant delay through amendments to the Form 13F.Our evidence supports hiding private information as the dominant motive for hedge...
