This paper proposes a methodology to analyze the implications of the Advanced Measurement Approach (AMA) for the assessment of operational risk put forward by the Basel II Accord. The methodology relies on an integrated procedure for the construction of the distribution of aggregate losses,...

All over the world, banks have been undergoing crisis, but the Nigerian experience has been hazardous to the country’s financial sector stability. Against this scenery, this paper investigates some cost efficiency correlates of a set of fifteen deposit money banks in Nigeria over the period...

We analyze the impact of the financial crisis on the structure and the dynamics of the Italian inter-bank market, focusing on monthly banks' assets and liabilities data between January 2007 and December 2010. The analysis is developed using an ad hoc data-set based on supervisory reports. The...

We introduce a smooth transition Generalized Pareto (GP) regression model to study the link between extreme losses and the economic context. The advantage of our approach consists in specifying a time-varying dependence structure between financial factors and the severity distribution of the...

Despite a surge in the research efforts put into modelling credit risk during the past decade, few studies have incorporated the impact that macroeconomic conditions have on business defaults. In this paper, we estimate a duration model to explain the survival time to default for borrowers in...

In this paper, we compare standard approaches used to handle losses in logarithmic stochastic profit frontier models with a simple novel approach. We discuss discriminatory power, rank stability and precision of profit efficiency scores. Our new method enhances rank stability and discriminatory...
