We study the nonparametric calibration of exponential, self-decomposable Lévy models whose jump density can be characterized by the k-function, which is typically nonsmooth at zero. On the one hand the estimation of the drift, the activity measure a := k(0+) + k(0-) and analog parameters for...

We estimate linear functionals in the classical deconvolution problem by kernel estimators. We obtain a uniform central limit theorem with square root n rate on the assumption that the smoothness of the functionals is larger than the ill-posedness of the problem, which is given by the polynomial...

Observing prices of European put and call options, we calibrate exponential Lévy models nonparametrically. We discuss the implementation of the spectral estimation procedures for Lévy models of finite jump activity as well as for self-decomposable Lévy models and improve these methods....

There is consensus that the recent nancial crisis revolved around a crash of the short-term credit market. Yet there is no agreement around the necessary policies to prevent another credit freeze. In this experiment we test the eects that contract length (i.e. maturity mismatch) has on the...

Lack of transparency in securitization transactions significantly contributed to the severe financial crisis of 2007–2009. To increase transparency we propose a new mechanism: financial claims with fingerprints. They would allow market participants at each stage of the securitization process...

At the peak of the financial crisis in October 2008, the IASB amended IAS 39 to grant companies the option of abandoning fair value recognition for selected financial assets. Using a comprehensive global sample of publicly listed IFRS banks, we find that banks use the reclassification option to...

The relation between the ECB’s main refinancing (MRO) rates and the money market is key for the monetary transmission process in the euro area. This paper investigates how money market rates respond to the new information revealed by MRO auctions. Our results confirm a stabilizing level...
