This article proposes omnibus specification tests of parametric dynamic quantile models. Contrary to the existing procedures, we allow for a flexible specification, where a possibly continuum of quantiles are simultaneously specified under fairly weak conditions on the serial dependence in the...

This paper presents a validation framework for collateral requirements or margins on a derivatives exchange. It can be used by investors, risk managers, and regulators to check the accuracy of a margining system. The statistical tests presented in this study are based either on the number,...

The experience of the 2007-09 financial crisis has showed that the bank capital regulation in place was inadequate to deal with "manufacturing" tail risk in the financial sector. This paper proposes an incentive-based design of bank capital regulation aimed at efficiently dealing with tail risk...

This paper presents a new method to validate risk models: the Risk Map. This method jointly accounts for the number and the magnitude of extreme losses and graphically summarizes all information about the performance of a risk model. It relies on the concept of a super exception, which is de.ned...

Se miden las ganancias potenciales de eficiencia de cinco fusiones de bancos, producidas entre 2005 y 2011, analizándolas con la metodología de análisis envolvente de datos. Dadas las divergencias entre modelos de rendimientos constantes y variables, se testean rendimientos para discernir...

In this paper I compare Schumpeter's and Keynes' views on the financing of economic activity. As will be seen, both economists share common ideas about the working and financing of market economies. In particular, both Keynes and Schumpeter reject the classical notions of the neutrality of money...
