Validation Panzar-Rosse Model in determining the structural characteristics of Tunisian banking industry
This paper investigates the market structure of banking industry in Tunisia and evaluates the degree of competition. The current analysis employs a widely used non-structural methodology put forward by Panzar and Rosse (1987), the so-called H-statistic, and draws upon a comprehensive panel dataset of Tunisian banks covering the period 1999 to 2008. The estimated H statistics for the whole sample periods are...

The long run effects of monetization on the Nigerian economy
This article uses a dynamic, dual-economy general equilibrium model that is adapted and modified to suit Nigeria’s situation to analyze the long-run effect of monetization policy on the Nigerian economy. The model provides a complete analysis of how output equation using Generalized Moments Method (GMM) variations affect aggregate consumption expenditure, investment, capital stock, labor, job cuts...

Modelling daily value-at-risk using realized volatility, non-linear support vector machine and ARCH type models
The aim of this paper is to compare the performance of the daily nonlinear support vector machines, the new semi-parametric tool for regression estimation, heterogeneous autoregressive (SVM-HAR)-ARCH type models based on the daily realized volatility (which uses intraday returns) with the performance of the classical HAR-ARCH type models by using different innovation distribution when the one-day ahead...
