    Abstract: The aim of this study is to identify the obstacles to the immigration of customer accounts from conventional bank to participative banking in Morocco. To achieve our objective, we carried out a quality study using a questionnaire administered to a sample of 317 Moroccan residents with a bank account with a conventional bank. The study revealed that a lack of knowledge about participatory banks and how they work, as well as poor marketing of banking products by participatory banks, are major obstacles to customers immigration their bank accounts to a participatory bank.

    Abstract: Demand for energy continues to grow, particularly in emerging economies. Like these economies, Morocco has invested significantly in renewable energies to meet the growing demand from its industry, which has been booming in recent years. The aim of this article is to examine whether an increase in renewable energy production has a positive impact on the Moroccan economy, which, like most of the world's economies, has suffered from rising oil prices and inflation following the recession, mainly due to the consequences caused by the coronavirus epidemic. The Moroccan economy, through a policy of migration or transition to renewable energies, is trying to lessen the negative effect of the recession by investing massively in renewable energies. Using data on the Moroccan economy, we test the contribution of renewable energies on the economy based on machine learning and neural networks through LSTM (LONG SHORT TERM MODELISATION) modeling. The empirical results show that an ever-increasing use of renewable energies can support the resumption of economic growth by generating a greater acceleration in GDP when compared with other variables.
    Abstract: La demande en énergie continue de croître, en particulier dans les économies émergentes. A l'instar de ces économies, le Maroc a investi de manière significative dans le domaine des énergies renouvelables pour satisfaire la demande croissante de son industrie qui est en plein essor ces dernières années. L'objectif de cet article est d'examiner si une augmentation de la production d'énergies renouvelables a un impact positif sur l'économie marocaine qui a souffert d'ailleurs comme la plupart des économies mondiales de la hausse des prix du pétrole et de l'inflation après la récession, cela est dû principalement aux conséquences causées par l'épidémie du coronavirus. L'économie marocaine, à travers une politique de migration ou de transition vers les énergies renouvelables essaie de diminuer l'effet négatif de la récession en s'investissant massivement dans les énergies renouvelables. En utilisant des données sur l'économie marocaine, nous testons la contribution des énergies renouvelables sur l'économie en se basant sur l'apprentissage automatique et le réseau des neurones par le biais de la modélisation LSTM (LONG SHORT TERM MODELISATION). Les résultats empiriques montrent qu'une utilisation toujours plus importante des énergies renouvelables peut soutenir la reprise de la croissance économique en générant une accélération plus importante du PIB en la comparant avec d'autres variables.

    Abstract: Persistent and successive external shocks have complicated policy execution. The ongoing war in Sudan, which erupted in April 2023, precipitated a significant refugee inflow into Egypt, with some 603, 000 Sudanese refugees registered with UNHCR as of December 31, 2024. Trade disruptions in the Red Sea since December 2023 have reduced foreign exchange inflows from the Suez Canal by US$6 billion in 2024, while transit trade volumes remain at about a third of pre-conflict levels, with further negative spillovers to growth and fiscal revenues.

    Abstract: Abstract: Foreign Direct Investment (FDI) flows in Morocco have been subject to fluctuations, influenced by the country's economic and political conditions. These fluctuations have had varying impacts on different sectors of the economy. Moroccan policies and incentives have aimed to create favorable conditions to attract multinational corporations and stimulate sectoral growth, leading to an increasing number of companies establishing themselves in Morocco. The study's central question is the role of local economic development in attracting FDI. Rather than focusing on the best relocation strategies for companies, the study aims to identify factors that make countries, particularly Morocco, attractive to foreign investment. To address this question, the study will employ an econometric approach, specifically multiple linear regression, to analyze the impact of various economic variables on inward FDI flows in Morocco. The analysis will be based on Moroccan data spanning from 1990 to 2022. The results indicate that while investment levels have a positive but statistically insignificant effect on foreign investment, economic growth, particularly its lagged effect, is an important factor in short-term foreign investment flows. Conversely, the openness index has a negative but insignificant relationship with FDI. These results highlight the central role of sustained economic growth in attracting Foreign Direct Investment and suggest that Moroccan policymakers should prioritize growth-oriented strategies to enhance the country's investment attractiveness and improve the long-term effectiveness of FDI.

    Abstract: Cereal production and markets, key components of Sudan’s food economy, have changed dramatically in the last decade due to conflict-related disruptions, as well as earlier changes in government policy. In western Sudan, particularly Darfur and surrounding regions, ongoing conflict has severely hindered agricultural activities, leading to a sharp decline in domestic cereal production. In contrast, other regions of Sudan have maintained relatively stable planting and harvesting activities, although marketing costs have risen substantially.

    Abstract: [TR] Bu calismada, Avrupa Birligi (AB) Sinirda Karbon Duzenleme Mekanizmasi (SKDM) kapsamindaki urunlerin Turkiye ihracatindaki yeri incelenmis ve ilgili urunlerin karbon emisyonu seviyeleri ulke karsilastirmali olarak ortaya konulmustur. Ayrica, Turkiye’den AB’ye SKDM urunu ihracati yapan firmalar ve bu firmalarin karakteristik ozellikleri hakkinda bilgi verilmistir. Ulke bazli veriler, Turkiye’nin AB’ye SKDM urun ihracatinda onde gelen ulkeler arasinda oldugunu ve soz konusu urunler bakimindan AB’den daha yuksek emisyon yogunluguna sahip oldugunu ortaya koymaktadir. Firma bazinda yapilan analizler ise, 2009-2023 donemi icin Turkiye’de yerlesik ihracatci firmalarin yaklasik yuzde 10-12’sinin AB’ye SKDM urun ihracati gerceklestirdigini ve bu ihracatin gorece buyuk firmalarda daha fazla oldugunu gostermistir. Buna ilave olarak, soz konusu firmalarin diger ihracatci firmalara gore ortalamada daha fazla firmayla ic ticaret iliskisi kurduklari ve yillar icinde gerceklestirdikleri tedarik ve satislarinin diger ihracatci firmalara gore daha yuksek oldugu gozlemlenmistir. [EN] In this study, the role of products under the scope of European Union (EU) Carbon Border Adjustment Mechanism (CBAM) in Türkiye’s exports is examined, and the carbon emission levels of these products are presented in a country-comparative manner. Furthermore, firms exporting CBAM products from Türkiye to the EU and their characteristics are presented. Country-level data reveal that Türkiye is among the leading countries in the CBAM product exports to EU and has higher emission intensities compared to the EU for these products. Firm-level analysis shows that for the period of 2009-2023, around 10-12% of Turkish exporting firms are involved in CBAM product exports to the EU, with larger firms accounting for a higher share of these exports. Additionally, it has been observed that these firms on average, establish domestic trade relationships with a greater number of firms than other exporting firms do and that their procurement and sales transactions throughout the years are higher compared to other exporting firms.

    Abstract: In recent years, the world has undergone profound transformations that have necessitated the re-evaluation and reformulation of economic concepts to align with the demands of evolving circumstances. In response to these changes, the scientific community must prioritize studying such concepts particularly, the notion of industrial sovereignty within a multidimensional and cognitive framework. This study is grounded in a scoping review conducted through a flexible and iterative approach, aiming to map the various dimensions of industrial sovereignty. It also incorporates a conceptual analysis to clarify key terms and frameworks. The research adopts a narrative and critical perspective, tracing the evolution of Moroccan industrial strategies within their historical and geopolitical context. Building on this theoretical analysis, the paper seeks to identify tools and criteria for measuring industrial sovereignty in Morocco. This is achieved through a comprehensive vision that not only enriches the conceptual understanding of the concept but also offers practical insights for its application in comparable economic contexts. By bridging theoretical exploration and historical analysis, the study aspires to advance the discourse on industrial sovereignty and its implications for economic resilience and strategic autonomy.
    Abstract: Durant ces dernières années, le monde a connu de profondes transformations nécessitant la réévaluation et la reformulation des concepts économiques afin de les adapter aux exigences d'un contexte en perpétuelle mutation. Face à ces évolutions, la communauté scientifique se doit de privilégier l'étude de ces concepts, en particulier de la souveraineté industrielle selon une perspective multidimensionnelle et cognitive. La présente recherche s'appuie sur une revue exploratoire (scoping review) menée selon une approche flexible et itérative, visant à cartographier les différentes dimensions de la notion de souveraineté industrielle. Elle mobilise également une analyse conceptuelle destinée à clarifier les concepts clés et les cadres d'analyse associés. Cette recherche mobilise également une démarche narrative et critique, en retraçant l'évolution des stratégies industrielles marocaines dans leur contexte historique et géopolitique. En se basant sur cette analyse théorique, ce travail de recherche vise à identifier les outils et critères permettant d'évaluer la souveraineté industrielle au Maroc. Cette démarche s'inscrit dans une vision globale, qui vise non seulement à enrichir la compréhension théorique du concept, mais aussi à fournir des pistes empiriques pour son application dans des contextes économiques similaires. En articulant l'exploration théorique et l'analyse historique, cette étude ambitionne de faire progresser la réflexion sur la souveraineté industrielle, tout en soulignant ses implications sur la résilience économique et l'autonomie stratégique.

    Abstract: [TR] Reel sektorun yabanci para (YP) cinsinden varlik ve yukumluluklerinin duzenli olarak takip edilmesi finansal istikrar acisindan onem tasimaktadir. Turkiye Cumhuriyet Merkez Bankasi (TCMB) bunyesinde kurulmus olan Sistemik Risk Veri Takip Sistemi (SRVTS), finansal olmayan firmalarin doviz pozisyonlarinin yakindan izlenmesine olanak saglamaktadir. Bu calismada, belirtilen sistem kapsaminda 2021 yili ocak ayindan itibaren verisi temin edilen, veri kalitesi kontrolleri sonucunda tutarli bulunan ve sektor temsil gucu yuksek olan firmalarin bilancolarindaki kur uyumsuzlugu incelenmektedir. Borclarin varliklara oraninin kur esnekligi olarak tanimlanan kur uyumsuzlugu kisa vadede sifira yakin ve 2024 yili basina kadar YP varlik payinin yuksek oldugunu gosterirken, uzun vadede YP yukumluluklerin payi daha yuksektir. Ayrica, bu firmalarin icerisinde dis ticaret islemleri bulunan firmalarin YP pozisyonunun belirleyicileri, firma seviyesindeki mikro veriler ile kur, beklenen enflasyon, faiz, cikti acigi ve kredi temerrut takasi (CDS) gibi makro veriler kullanilarak tahmin edilmistir. Sonuclar, vade yapisina gore farklilik gostermektedir. Kisa vadede firmalarin YP pozisyonuyla kur degisiminin ters yonlu iliskili oldugu bulgulanmistir. Uzun vadede ise ihracat ve beklenen enflasyonun YP pozisyonunu pozitif yonde etkiledigi gorulmustur. Ek olarak, her iki vade kiriliminda da kur oynakligindaki artisin firmalarin doviz pozisyonlari uzerinde artirici yonde etkili oldugu izlenmistir. Tahminler, imalat sektoru firmalari ve nette ihracatci firmalar icin tekrarlandiginda bulgular orneklem genelinden farklilik gostermemektedir. [EN] Monitoring the foreign currency assets and liabilities of the real sector regularly is crucial for financial stability. Systemic Risk Data Monitoring System, established within the Central Bank of the Republic of Türkiye, enables close monitoring of the foreign exchange positions of non-financial companies. In this study, the exchange rate mismatch in the balance sheets of companies, whose data were obtained since January 2021 within the scope of system, which are found to be consistent as a result of data quality checks, and have high sector representation is examined. The exchange rate mismatch, defined as the exchange rate elasticity of the ratio of liabilities to assets, is close to zero in the short term and shows that the share of FX assets is high until the beginning of 2024, while the share of FX liabilities is higher in the long term. Furthermore, the determinants of foreign currency positions for firms involved in foreign trade operations are estimated using firm-specific micro data and macroeconomic data such as exchange rates, expected inflation, interest rates, output gap, and credit default swaps (CDS). Analysis results are different depending on the maturity structure. In the short term, it is found that the FX position of the firms is negatively affected by the exchange rate change in a statistically significant way. In the long term, it is seen that the export and expected inflation variables affect the FX position positively. It is also found that the exchange rate volatility has a positive effect on the FX positions of the firms in both maturity breakdowns. The estimates are repeated for manufacturing sector firms and net exporting firms and the results do not differ from the overall sample.

    Abstract: The structural reforms of the public sector, to which Morocco has committed, have prompted public administrations to gradually transition from a resource-based management model to a results- or performance-based approach. This shift is justified not only by the need to enhance service quality for users but also by the rational use of resources, ensuring the delivery of high-quality public services at a lower cost. Being part of the public sector, Morocco's penitentiary and rehabilitation administration operates within a distinct environment that demands continuous improvements in performance. Achieving these objectives requires the adoption of managerial practices designed to optimize outcomes. In this context, our research aims to critically assess performance management in this administration and explore existing practices and their limitations, drawing on the reference framework of Ferrera and Otley (2009) and applying participant observation over a specific period (David, 2010). Our analysis also drew on a wide-ranging literature review and interviews with 14 stakeholders in the field, to gain a deeper understanding of the dynamics at work. The study's findings highlight the administration's proactive, efforts to enhance performance management through the mechanisms it adopts. However, these mechanisms raise some observations regarding their consistency, complementarity, implementation, and, more broadly, their effectiveness in addressing users' actual needs and the administration's management specificities.
    Abstract: Confrontée à une pression managériale insistant sur la modernisation et l'amélioration de la performance de ses services et compte tenu du retard accusé dans le processus de réforme du système pénal limitant ses marges de manœuvres, l'administration pénitentiaire et de réinsertion au Maroc doit exécuter les décisions d'emprisonnement alors que les prisons sont déjà surpeuplées. Elle doit également prendre en charge, avec des ressources humaines et financières limitées, une population spécifique qui s'accroît de façon inquiétante. Ce travail de recherche s'est assigné comme objectif d'apprécier les résultats des réformes ayant touché cette administration. Dès lors, et en s'appuyant sur une large revue de littérature sur la question carcérale couplée à une étude des rapports et statistiques de la Délégation Générale à l'Administration Pénitentiaire et à la Réinsertion (DGAPR), mais également nos observations dans le cadre d'une méthodologie de recherche-action, nous avons pu soulever les enjeux auxquels cette administration est confrontée dans sa quête d'amélioration de sa gestion. Les pistes de modernisation proposées touchent les aspects législatif, stratégique et organisationnel.

    Abstract: In an environment characterized by rapid technological change, the digital transition is emerging as a crucial strategic challenge for companies. It is not just about adopting new technologies, but also about rethinking processes, business models and management practices. The effect on the performance of organizations is of growing interest to both researchers and professionals. The objective of this article is to examine the link between digital transformation and business efficiency by examining various key dimensions: improving customer relations, the value of digital skills, improving internal processes and the impact of digital platforms. By analyzing the data collected from a sample of Moroccan enterprises, it is necessary to assess the extent to which these factors contribute to increased competitiveness and organizational efficiency. Ultimately, this study will help identify the major challenges associated with digitization and provide recommendations to support businesses in their transition to digital. The study has some limitations, including sample size which could be increased for better representativeness. Thus, the data used are primary data. Despite these difficulties, interesting results have been achieved.
    Abstract: Dans un environnement caractérisé par une évolution technologique rapide, la transition numérique s'impose comme un défi stratégique crucial pour les entreprises. Elle ne consiste pas uniquement à adopter de nouvelles technologies, mais aussi à revoir les processus, les modèles économiques et les méthodes de gestion. L'effet sur la performance des organisations suscite un intérêt grandissant, aussi bien pour les chercheurs que les professionnels. Cet article a pour objectif d'examiner le lien entre la transformation digitale et l'efficacité des entreprises en scrutant diverses dimensions essentielles : l'amélioration de la relation client, la valeur des compétences numériques, l'amélioration des processus internes et l'impact des plateformes numériques. Par l'analyse des données collectées auprès d'un échantillon d'entreprises marocaines, il convient d'apprécier dans quelle mesure ces éléments participent à l'accroissement de la compétitivité et de l'efficacité organisationnelle. Cette étude aidera à cerner les défis majeurs associés à la numérisation et à fournir des recommandations pour soutenir les entreprises dans leur passage au numérique. L'étude comporte quelques limites, dont la dimension de l'échantillon qui pourrait être augmentée pour une meilleure représentativité. Ainsi, les données utilisées sont des données primaires. Malgré ces difficultés rencontrées, des résultats intéressants ont été obtenus.

    Abstract: In 2024, Morocco launched its ‘Maroc Digital 2030' strategy aimed at transforming the country into a digital leader in Africa. This strategy aims to improve the accessibility and efficiency of public services by digitising them. This includes creating a unified digital portal to centralise access to government services, simplifying administrative procedures and improving the user experience. The rapid development of digital technologies has profoundly changed the behaviour of all stakeholders involved in urban management. E-participation is vital to foster economic and social development. The aim of this research is to explain the factors influencing online citizen participation and to propose a conceptual model integrating these variables. More specifically, this work examines the impact of expected effort in using the technology, perceived usefulness, attachment to the territory and perceived trust on the intention to use participatory platforms. In addition, the research introduces gender and sex as moderating variables to analyse how the relationships between these factors vary according to individual characteristics. Understanding the factors that influence the uptake of e-participation is essential for the strategy, planning, design and dissemination of e-participation initiatives that will ultimately motivate citizens to use them. This article also explores the technological and individual factors that influence citizens' decision to participate online. Based on the UTAUT (United Theory of Acceptance and Use of Technology) theoretical model. The research methodology of this article is based on an in-depth analysis of the literature review, we identified the relevant variables and formulated the hypotheses to be tested within the framework of the conceptual model. The expected results aim to enrich the literature on e-participation in order to implement a participatory approach adapted to the specific expectations of citizens.
    Abstract: Le Maroc a lancé en 2024 sa stratégie "Maroc Digital 2030" visant à transformer le pays en un leader numérique en Afrique. Cette stratégie vise à améliorer l'accessibilité et l'efficacité des services publics en les numérisant. Cela inclut la création d'un portail numérique unifié pour centraliser l'accès aux services gouvernementaux, la simplification des procédures administratives et l'amélioration de l'expérience utilisateur. En effet, l'évolution rapide des technologies numériques a profondément modifié le comportement de toutes les parties prenantes impliquées dans la gestion urbaine. L'e-participation est vitale pour favoriser le développement économique et social. L'objectif de cette recherche est d'expliquer les facteurs influençant la participation citoyenne en ligne et de proposer un modèle conceptuel intégrant ces variables. Plus précisément, ce travail examine l'impact de l'effort attendu dans l'usage de la technologie, de l'utilité perçue, de l'attachement au territoire et de la confiance perçue sur l'intention de l'usage des plateformes participatives. En outre, la recherche introduit le genre et le sexe comme variables modératrices pour analyser comment les relations entre ces facteurs varient en fonction des caractéristiques individuelles. Comprendre les facteurs qui influencent l'adoption de l'e-participation est essentiel pour la stratégie, la planification, la conception et la diffusion des initiatives de l'e-participation qui finiront par motiver les citoyens à les utiliser. Cet article explore aussi les facteurs technologiques et individuels qui influencent la décision des citoyens à la participation en ligne. En s'appuyant sur le modèle théorique UTAUT (United Theory of Acceptance and Use of Technology). La méthodologie de recherche de cet article repose sur une analyse approfondie de la revue de la littérature, nous avons identifié les variables pertinentes et formulé les hypothèses à tester dans le cadre du modèle conceptuel.

    Abstract: The emergence of the knowledge economy has led many organizations to recognize the importance of knowledge as a crucial resource, and has created a complex management challenge "knowledge management (KM)". Due to cultural, operational, geographic dispersions and other complexities, this challenge is more acute for larger organizations. Performance is a contextual concept associated with the phenomenon studied. In recent years, several theories have been put forward for the practice of KM. However, given the abstract nature of the field, there is little consensus on the components and modes of knowledge management. Much of the current research focuses on one or a few organizational elements of knowledge management. The critical and fundamental relationships between all elements are often overlooked. The need for theories, principles and empirical methods for knowledge management is widely recognized in the existing management literature. Thus, the main motivation of this research is to develop a broad model in the form of a holistic framework for corporate knowledge management and to highlight the tangible impacts of knowledge management on Moroccan companies subject of the The case study carried out in 2019/2020 and presents instruments for measuring the return on investment of Knowledge management projects and programs, contributed to a good understanding of the benefits of KM in the company. The research study is carried out with an interpretative paradigm and the non-demonstrative induction approach to explore and describe various factors influencing the practice of knowledge management in organizations and a case study research strategy. In-depth case studies were conducted in nine large organizations, the empirical case study material was collected and analyzed in detail using a grounded theory approach. Keywords : Knowledge management ; culture of sharing ; intellectual capital ; competitiveness ; communities of practice.
    Abstract: P a g e 2 | 18Résumé L'émergence de l'économie de la connaissance a conduit de nombreuses organisations à reconnaître l'importance de la connaissance comme une ressource cruciale, et a créé un défi de gestion complexe « la gestion des connaissances (KM) ». En raison des complexités culturelles, opérationnelles, dispersions géographiques et autres, ce défi est plus aigu pour les grandes organisations. La performance est un concept contextuel associé au phénomène étudié. Au cours des dernières années, plusieurs théories ont été avancées pour la pratique de GC. Cependant, étant donné la nature abstraite du domaine, il y a peu de consensus sur les composants et les modes de gestion des connaissances. Une grande partie de la recherche actuelle porte sur un ou quelques éléments organisationnels de la gestion des connaissances. Les relations critiques et fondamentales entre tous les éléments sont souvent ignorées. Le besoin de théories, principes et méthodes empiriques pour la gestion des connaissances est largement reconnu dans la littérature existante sur la gestion. Ainsi, la motivation principale de cette recherche est de développer un modèle large sous la forme d'un cadre holistique pour la gestion des connaissances d'entreprise et de mettre en lumière les retombées tangibles de la gestion des connaissances sur la performance des entreprises marocaines sujet de l'étude de cas réalisé en 2019/2020 et de présenter des instruments de mesure de retour sur investissement des projets et programmes du knowledge management, de contribué à une bonne compréhension des bénéfices de la GC pour l'entreprise. L'étude de recherche est réalisée avec un paradigme interprétatif et la démarche d'induction non démonstrative permettant d'explorer et de décrire divers facteurs influençant la pratique de la gestion des connaissances dans les organisations et d'une stratégie de recherche par étude de cas. Des études de cas approfondies ont été menées dans neuf grandes organisations, le matériel empirique de l'étude de cas a été collecté et analysé en détail à l'aide d'une approche fondée sur la théorie ancrée.

    Abstract: Iraq has managed to uphold domestic stability despite regional turmoil. However, rapid expansion of spending and emerging financing constraints led to arrears accumulation in 2024. These challenges are now compounded by declining oil prices in a highly uncertain global environment, further aggravating fiscal and external sustainability risks. At the same time, the country is struggling with lingering structural economic challenges, including high unemployment, excessive state footprint, a weak banking sector, corruption, and an inefficient electricity sector.

    Abstract: Résumé : Dans cette étude, nous nous sommes concentrés sur l'existence de bulles financières dans le contexte du marché boursier marocain, en faisant référence à l'indice MASI. Reconnaissant la présence d'une bulle pendant la période 2003-2008, nous avons utilisé le test ADF, qui est une technique standard utilisée pour traiter les racines unitaires dans les séries chronologiques. Cette période a été marquée par une frénésie générale du marché boursier et s'est terminée avec la crise financière mondiale de 2008, et nos résultats sont donc cohérents avec des études précédentes qui ont montré que des bulles s'étaient formées dans d'autres marchés émergents. Cependant, il est important de noter que le test ADF a ses propres limites. Sa sensibilité aux points de rupture et aux changements de régime peut parfois entraîner des résultats biaisés. De plus, le fait qu'une racine unitaire ait été prétendument existante n'est pas une preuve catégorique de la présence active d'une bulle. Il existe également d'autres méthodes telles que les tests GSADF ou les modèles de changement de régime qui pourrait apporter des éclairages supplémentaires. En dehors des considérations statistiques, il est également important d'évaluer les déterminants psychologiques et fondamentaux de l'émergence des bulles. Le comportement de troupeau, la confiance excessive, les biais cognitifs, les conditions économiques favorables et une politique monétaire accommodante.

Recognizing the presence of a bubble during the period 2003-2008, we used the ADF test, which is a standard technique used to address unit roots in time series. This period was marked by a general frenzy in the stock market and ended with the global financial crisis of 2008, and our results are therefore consistent with previous studies that showed bubbles had formed in other emerging markets. However, it is important to note that the ADF test has its own limitations. Its sensitivity to breakpoints and regime changes can sometimes lead to biased results. Moreover, the fact that a unit root was allegedly present is not conclusive evidence of the active presence of a bubble. There are also other methods such as GSADF tests or regime change models that could provide additional insights. Apart from statistical considerations, it is also important to evaluate the psychological and fundamental determinants of the emergence of bubbles.

    Abstract: This study examines the health and economic repercussions of the 2018 Chikungunya epidemic on households in Kassala State, Sudan. The study draws on primary survey data from 407 households sampled proportionally across the localities of Kassala, Rural Kassala, and Rural West Kassala. The epidemic displayed widespread prevalence, with infection rates highest in urban areas due to greater population density and vector exposure. The study finds that existing socioeconomic vulnerabilities, particularly high illiteracy rates, female-headed households, and low-income prevalence in rural localities, substantially exacerbated financial pressures on affected households. The results from ordered logistic regression reveal that Chikungunya infection significantly increases out-of-pocket health expenditures (OOPHE), while health insurance offers notable financial protection. Furthermore, probit regression analysis confirms that catastrophic health expenditure (CHE), defined as OOPHE exceeding 20% of household income, is common across all income groups and strongly correlated with infection status. Elevated OOPHE is further shown to depress household consumption levels, deepening poverty risks, especially among economically disadvantaged groups. In coping with these health shocks, the majority of households turned to borrowing and informal support networks, highlighting the limited reach of formal safety nets. Taken together, these findings point to the urgent need for robust public health interventions, expanded insurance coverage, and strengthened financial protection systems. Enhancing epidemic preparedness through improved vector control, health education, and equitable access to healthcare is essential to safeguarding vulnerable populations and promoting resilience in Kassala State and similar contexts in Sudan.

    Abstract: This study is of utmost importance as it examines the direct impacts (losses and damages) on the economic, social, and service sectors of the Gaza Strip and contributes to providing a concrete proposal based on an empirical approach to the expected reconstruction and recovery scenarios after the war. The study is based on a purely positivist methodology in order to avoid any standard proposals and formulate a more specific approach that reviews reconstruction scenarios according to the available local, international, and regional data. This is done in light of the specific role of occupation authorities in terms of their relationship with the Gaza Strip. The study concludes that recovery and reconstruction may require around 54 billion US dollars, including housing, economic recovery, relief interventions, emergency shelter, and support for vital and health sectors. Under the optimistic scenario, the reconstruction process may require 8 years of intensive and organized work in parallel with the availability of international will and necessary funding, not to mention the necessity of lifting the occupation's restrictions on crossings and the entry of building materials and heavy machinery. True reconstruction can only be discussed within an integrated package of liberation development that includes, in addition to recovery, strengthening the Palestinian presence.

    Abstract: L'intégration de la technologie blockchain sur le marché financier promet un véritable développement du marché. Elle peut transformer l'organisation et le fonctionnement du marché, en créant un système décentralisé et distribué qui apporte plus de transparence et de sécurité nécessaire au développement du marché financier. L'objectif principal de ce papier est alors d'analyser si l'intégration de la technologie blockchain améliore la résilience du marché financier, en prenant le cas de la Bourse de Casablanca. La méthode utilisée est une analyse comparative entre la résilience du marché financier et celle de la blockchain en utilisant les réponses impulsionnelles du modèle VAR (TVP-VAR). Les deux évènements choisis pour analyser la résilience sont la période du Covid-19 et de la guerre Russe-Ukraine. Les résultats de l'étude démontrent alors clairement que la technologie blockchain permet un retour à l'équilibre plus rapidement après la survenance d'un choc et son intégration sur le marché améliorera sa résilience.

    Abstract: This study aims at forecasting the future behavior of budget variables, using Artificial Neural Network (ANN) and Deep Neural Network (DNN) techniques for Türkiye. Particularly, we focus on budget expenditures, tax revenues and their main components. Annual data were used and divided into two sub-periods: a training set (2002-2019) and a test set (2020-2022). Each fiscal item is estimated using relevant explanatory variables selected based on economic theory. We achieved good forecasting performance for main budget items using ANN and DNN methodologies. We found that most of the Mean Absolute Error (MAE) values fell within the acceptable range, an indicator of good prediction performance. Second, we see that the MAE values for public expenditures are lower than taxes. Third, estimating total tax revenues (aggregate data) performs better compared to subcomponents of taxes (disaggregated data). The opposite is the case for public expenditures.

    Abstract: The goal of this study is to identify the most effective model for predicting credit risk, the likelihood a commercial loan defaults (become a non-performing loan) in the Turkish banking sector and to determine which firm and loan characteristics influence that risk. The analysis draws on an unbalanced dataset of 1.2 million firm-level observations for 2018–2023, combining financial ratios with detailed loan- and firm-specific information. Class imbalance is addressed through oversampling (including SMOTE) and multiple down-sampling schemes. Although the risk is assessed ex-ante, model performance is evaluated ex-post using the ROC-AUC metric. Within tested conventional econometric and machine learning approaches accompanied with different sampling techniques, Extreme Gradient Boosting (XGBoost) with oversampling delivers the best result with a ROC-AUC score of 0.914. Compared with logistic regression under the same sampling setup, a 4.9- percentage-point increase in test ROC-AUC is attained, confirming the model’s superior predictive performance over conventional approaches. Accordingly, the study finds that the industry and location in which a firm operates, its loan-restructuring status, loan cost and type (fixed vs. floating rate), the firm’s record of bad checks, and core ratios capturing profitability, liquidity and leverage to be the most influential predictors of credit risk.

    Abstract: This paper investigates the firm heterogeneity in the evolution of loan spreads over the credit cycle in Türkiye. Using the combination of credit registry and administrative datasets, our bankfirm level analysis shows that small- and medium-sized enterprises (SMEs) and firms that are riskier and more prone to financial frictions pay higher loan interest rates. The results also reveal that loan spreads of these firms decrease and converge to the spreads of large and financially sound firms during expansion periods. Our firm-level analysis indicates that these findings persist at the firm level. Our results suggest that SME loan spreads rise more than those of larger firms during tightening periods. This reveals the asymmetric deterioration in SMEs’ lending conditions relative to large firms. On the other hand, the significant role of firm riskiness on loan spreads weakens during expansion periods. However, these findings are valid only for loans extended by private banks but not state-owned banks. Our findings lend support to policy makers’ prudent approaches over the credit cycle.

    Abstract: La qualité de l'information comptable et financière est étroitement liée au référentiel utilisé pour sa production. Chaque cadre comptable s'appuie sur des objectifs, des principes et des utilisateurs spécifiques, ce qui conduit à des attentes vis-à-vis de l'information comptable varient selon le système comptable en vigueur. Cet article vise à travers une analyse comparative à explorer comment la qualité de l'ICF est abordée par les normalisateurs internationaux, en particulier à travers les cadres conceptuels du FASB et de l'IASB, d'une part, et par le cadre réglementaire comptable marocain, d'autre part.En résumé, le CGNC, qui constitue le référentiel de la normalisation comptable marocaine, ne couvre pas l'ensemble des qualités de l'information comptable, il en précise trois caractéristiques qualitatives à savoir la pertinence, la fiabilité et la comparabilité, qui se trouvent également dans le cadre conceptuel anglo-saxon (IASB-FASB). Cependant, des divergences apparaissent dans la définition de ces qualités, en raison notamment des différences liées aux destinataires privilégiés de l'information et aux principes comptables fondamentaux sur lesquels reposent les référentiels respectifs.
