The Loss Distribution Approach has many appealing features since it is expected to be much more risk - sensitive than any other methods taken into consideration by the last proposals by the Basel Committee. Thus this approach is expected to provide significantly lower capital charges for banks...

In this paper, we explore the Loss Distribution Approach (LDA) for computing the capital charge of a bank for operational risk where LDA refers to statistical/actuarial methods for modelling the loss distribution. In this framework, the capital charge is calculated using a Value-at-Risk measure....

In this paper, we consider the use of interest rate contingent claims as indicators for the monetary policy. We analyze two approaches: one based on the term structure of zero bonds and another based on interest-rate option derivatives. We show how traditional tools based on the Black framework...

In this short note, we consider some problems of two - asset options pricing. In particular, we investigate the relationship between options prices and the 'correlation' parameter in the Black - Scholes model. Then, we consider the general case in the framework of the copula construction of risk...

In this paper, we consider Hopscotch methods for solving two - state financial models. We first derive a solution algorithm for two - dimensional partial differential equations with mixed boundary conditions. We then consider a number of financial applications including stochastic volatility...

Intense reflections are being conducted at the moment regarding the way to pool heterogeneous data coming from both banks' internal systems and industry-pooled databases. We propose here a sound methodology. As it relies on maximum likelihood principle, it is thus statistically rigorous and...

Copula functions have been introduced recently in finance. They are a general tool to construct multivariate distributions and to investigate dependence structure between random variables. In this paper, we show that copula functions may be extensively used to solve many financial problems. As...

This paper demonstrates that aggregate losses are necessarily low as long as we remain under the standard assumptions of LDA models. Moreover empirical findings show that the correlation between two aggregate losses is typically below 5%, which opens a wide scope for large diversification...

This paper follows the different steps necessary for implementing a LDA in practice: - Step 1: Severity Estimation - Step 2: Frequency Estimation - Step 3: Capital Charge Computations - Step 4: Confidence Interval - Step 5: Self Assessment and Scenario Analysis For each of these steps, we try to...

The liquidity of exchange traded funds is of utmost importance for regulators, investors and providers. However, the study of liquidity is still in its infancy. In this work, we show some stylised facts of liquidity statistics (daily/intraday spread, trading volume, etc.). We also propose a new...
