This paper explores the influence of corporate governance on the profitability and credit risk of a sample of listed banks in Tunisia. The methodology involves two main steps. Firstly, principal component analysis is employed to construct a novel governance index, assessing the quality of both internal and external bank governance. This index takes into account the degree of compliance and application of directives and laws mandated by the Tunisian Central Bank regarding banking governance. In the second step, panel data analysis is conducted to scrutinize the impact of internal and external governance mechanisms on the profitability and risk of Tunisian banks. The results reveal that as the governance index increases, the profitability of banks improves in terms of return on assets and stock market performance. Additionally, a higher governance index is correlated with a reduction in credit risks, as indicated by lower instances of non‐performing loans and an increased rate of coverage for classified debts. To enhance the robustness of our results, we calculate a standard governance score based on existing empirical literature. Furthermore, to account for potential endogeneity, we employ the two‐step system generalized method of moments. [ABSTRACT FROM AUTHOR]

This dissertation is comprised of three empirical essays dealing with some aspects of poverty analysis. The firstone combines both unidimensional and multi-dimensional approaches to analyze poverty. First of all, through theFoser-Greer-Thorbeek index we present a first analysis of the Tunisian poverty profile. Secondly, we estimate aclassic logit model using the same variables. Finally, we introduce a new approach based on fuzzy logic (Zadeh,1975) able a comparison between logit model and fuzzy approach by building a membership function based on thelogistic function. The execution of this models require the choice of well-being indicator, generally, the incomeor he consumption. In this PhD thesis, we favor the reel per capita consumer expenditures of households. Theprincipal reasons of this choice are twofold: The first one, income is hardly observable due to a bad quality ofdata. The second reason is that consumer expenditures are stable over time comparing to income. Finally, we testthe robustness of our work and he choice of the poverty line using sensitivity test and the concept of stochasticdominance. The second essay, focuses on the determinants of household welfare in Tunisia. Welfare is measuredby real per capita household expenditure (income). We examine the inequality gap in consumption and educationin rural and urban areas. Our empirical analysis relies on the Tunisian Living Standards Surveys of 2010. Ourpaper makes two original empirical contributions to the literature compared to previous. In order to analyze thegap between the two regions, we apply the RIF- regression advanced by Firpo et al. (2011) and the new counterfactualdecompositions developed by Chernozhukov et al. (2013). We also use censored and uncensored quantilesregressions for disaggregate consumption expenditures. This study offers another analysis of the influence of someindicators such as health, food expenditures and especially education on regional disparities in developing countries.It also examines the relationship between these indicators and development disparities across the two areas.The third essay of this thesis aims to explain the determinants of poverty dynamics. Unfortunately in Tunisia,as in most developing countries, panel data are not available. We introduce a new approach able us to execute adynamic analysis of poverty using potential outcomes approach and multiple imputation. In fact, the study basedon two steps. First of all, we use a Bayesian algorithm which combines the two approach, cited previously, inorder to penalize the data base. In the second step, we assess poverty dynamics through two different methods.On the one hand, we use static measurement of poverty through the Jalan-Ravallion and the Equally-DistributedEquivalent Poverty Gaps approaches. On the other hand, we execute an econometric procedure by estimating arecursive bivariate probit model. This model allows to treat the initial condition of poverty as endogenous whichavoids a probable bias-selection., Cette thèse est composée de trois essais empiriques qui visent à analyser la pauvreté en Tunisie. La premièrepartie est consacrée à une étude unidimensionnelle et multidimensionnelle de la pauvreté. Nous mesurons de lapauvreté en fonction de l’indice composite FGT (Foster-Greeck-Thorbecke) et la régression logistique et nousintroduisons une nouvelle approche basée sur la logique floue. A la fin de ce chapitre, nous testons la robustessede notre travail et de notre choix de la ligne de pauvreté, en introduisant le concept de dominance stochastique etle test de sensibilité. La réduction de la pauvreté et de l’inégalité dans les pays en voie de développement est unsujet courant de nos jours. En particulier en Tunisie les efforts se sont concentrés sur la réduction de l’inégalité etl’écart en terme de bien être entre les zones rurales et les zones urbaines. Malgré toutes les procédures prises parl’Etat, l’écart est toujours profond. Les études antérieures ont mis en valeur le rôle crucial de certaines variablesà savoir l’éducation pour réduire le gap entre les deux zones. Le deuxième chapitre vise à vérifier ce résultat, àdistinguer les déterminants de bien être dans les deux zones, et à décortiquer l’origine de la persistance de cetécart en utilisons la regression par quantile et quantile censuré pour identifier les déterminant de bien etre dansles zones rurales et les zones urbaines. Et pour décortiquer l’écart entre les deux zones et vérifier si la persistancede cet écart est dû à l’effet caractéristiques ou bien à l’effet rendement de ces caractéristiques, nous utilisons ladecomposition RIF proposée par Firpo et al. (2011) et une nouvelle approche de décomposition contrefactuelleproposée par Chernozhukov et al. (2013). Mener une étude dynamique nous amène à penser aux données depanel. Malheureusement, dans les pays en voie de développement, et spécialement en Tunisie, ce genre de base dedonnées sur le bien être des individus n’est pas disponibles. Afin de contourner ce problème, plusieurs chercheursont eu recours à la technique de pseudo panel (citons à titre d’exemple Ben Rejeb (2008)), mais cette méthode aété délaissée car elle ne prend pas en considération la pauvreté between-individus de la même cohorte. Nous proposonsainsi une nouvelle approche, qui nous permet d’effectuer ce genre d’analyse, basée sur l’inférence causaleet l’imputation multiple. Les résultats de cette étude ont contribué aux travaux existants concernant l’analyse de lapauvreté en Tunisie. Par rapport aux études antérieures, notre analyse met en évidence le facteur migration interneentre les régions. Ce point nous permet de prédire plusieurs scénarios concernant le changement de résidence desindividus et son influence sur les différentes composantes de la pauvreté. Au total cette étude permet de dégagerplusieurs conclusions et de proposer quelques recommandations pour l’amélioration des politiques de lutte contrela pauvreté.

This paper examines urban‐rural welfare inequality in Tunisia. Using the recentred influence function and quantile regression based counterfactual decomposition, we analyse the gap between the two areas. Results of the present study suggest that the difference between rural poor households and urban poor households is due essentially to characteristic effects; while for wealthier households both characteristic and returns to these characteristic effects (for example, efficiency of educational system) are responsible for this gap. Additionally, the results demonstrate that this is an issue of value, and, more specifically, an economic development fairness conflict. It is suggested that policymakers should address a positive discrimination programme in favour of the marginalized region.

This paper uses household desegregated expenditure data to assess the differential impact of consumption expenditure and its components across different expenditures quintiles, between urban and rural regions in Tunisia. It also provides assessment of poverty at east-west level. Using a new approach of semiparametric censored regression model, this paper offers another analysis of the sensitivity of some indicators such as health, food and education, with regional disparity in Tunisia. Socio-demographic characteristics and economic factors, such as educational level, employment sector, and returns to those characteristics (i.e. quality of hospital equipment, level and quality of educational system etc.) were found to be important determinants of urban-rural household welfare disparities. Meanwhile, the paper proposed some policies recommendation based on micro/macro mechanisms in order to reduce regional inequality in Tunisia. [ABSTRACT FROM AUTHOR]
