In a Constant Proportion Portfolio Insurance (CPPI) framework, a constant risk exposure is defined by the multiple of the strategy. This article proposes an alternative conditional multiple estimation model, which is based on an autoregressive quantile regression dynamic approach. We estimate...

We consider the problem of testing whether the observations X1, · · ·, Xn of a time series are independent with unspecified (possibly nonidentical) distributions symmetric about a common known median. Various bounds on the distributions of serial correlation coefficients are proposed:...

The objective of this paper is to provide a complete framework to aggregate different quantile and expectile models for obtaining more diversified Value-at-Risk and Expected Shortfall measures, by applying the diversification principle to model risk. Following Taylor (2008) and Gouriéroux and...

This study tests an international extension of the Asset Pricing Model (CAPM) based on the coexistence of two risk causes. The first cause is linked to the market portfolio and the second one is required by expectations about the variation of exchange rates. Through an application to various...

We study the relationships between the real effective exchange rate (REER) of the Tunisian dinar and its determinants/fundamentals, i.e. the ratio of trade balance/GDP, the ratio of public consumption/GDP, the openness rate and the terms of trade. We find that in the most of cases, the variables...

The excess liquidity of commercial banks is very often mentioned in the CEMAC as one of the limits of monetary policy implementation by BEAC. In this paper, we tried to address excess reserves in the CEMAC banking system looking from the point of view of commercial banks. Indeed, commercial...

The study results presented here are derived from a process whose purpose was the initial deployment and use of the data envelopment analysis techniques and linear programming in R environment to verify the feasibility of transferring tools supporting analyzes conducted after the project...

This paper analyzes the potential effects of new capital requirements of banks in the WAEMU countries on the cost of credit in Togo. The influence on lending rates is examined through the channel of the of banking concentration. We show from generalized additive models (GAM) and generalized...

Cet article vise à identifier un processus non linéaire par la méthode du noyau. Cette identification nécessite une sélection rigoureuse des coefficients de Markov et le choix de la fenêtre qui détermine le degré de lissage de l’estimateur. This paper aims to identify a nonlinear...
