📄 The objective of this article is to explain the determinants of access to credit in formal financial institutions for microenterprises by non-traditional factors, namely the possession of a mobile account without having an account in traditional financial institutions, the fact of being a member of a tontine or a mutual aid association. The methodology used is based on the estimation of the logit model with data from the Integrated Household Living Conditions Survey for 2019-2020 (EICVMB, 2019-2020) of the National Institute of Statistics of Burundi (INSBU). All other things being equal, the main results show that i) having a mobile banking account has a positive effect on access to credit (0.02751%), ii) even if the microentrepreneur does not have a traditional account (0.0322%), iii) and that being a member of a tontine or mutual aid association has a negative effect on access to credit (-0.02723%). For tontine groups to be a genuine source of finance for micro-businesses, especially those in rural areas, and thereby help to increase financial inclusion, these results call on the political authorities and financial service providers to work in synergy to develop the use of mobile banking in the provision of financial services, to develop appropriate support infrastructures, and to set up support modules for tontine groups, especially in rural areas.

📄 This article contributes to the study of the determinants of profitability of commercial banks using the new techniques of dynamic estimation of data in panel. The objective is to evaluate the prudential policy assigned to African banks to assess the financial strength of these banks in the face of insolvency factors in their main credit distribution function, so that they can properly maintain sufficient long-term growth. This approach takes into account internal bank and external factors related to the country’s macroeconomic situation. The approach consists of applying new generations of data panel models to a sample of 8 Congolese banks between 2010 and 2022. We found that size, capitalization and inflation rate are factors that influence profitability of commercial banks in the DRC. Several policy implications flow from our analysis. Banks are urged to consolidate their own funds and diversify their activities and the state must restore confidence in the banking system to enable banks to play their full roles in mobilizing savings and distributing credit.

📄 Prudential regulation is crucial for banking oversight, ensuring sector safety and stability. However, its tools are debated. Comparing literature is key, as banking’s unique characteristics drive regulation. Traditional theories, like state preference and portfolio choice, assume complete and perfect markets, making them ill-suited for banking specifics. New “optimal regulation” models incorporate information asymmetries to better address these specifics, though only partially. This evaluation highlights the need for theoretical approaches that fully account for the unique nature of banking.

📄 he paper focuses on funding small enterprises in the context of Burundi. It particularly highlights the role of informal funds and requirements to achieve their objectives. In the process of their development, small enterprises use external funds resources. These resources may be formal or informal. The theoretical analysis of funding small enterprises in Burundi shows that, the informal financial system plays an important role in the funding of small enterprises. More so, the existence of informal funds shows that there are categories of economic agents who can neither access nor use formal financial services. Therefore, with adequate measures of accompaniment, the informal finances will be an important source of mobilization of funds resources of the economy. Therefore, the informal funding system should be backed by regulatory and control agencies for them to achieve their objectives.

📄 Les microentreprises (ME) jouent un rôle important dans les économies des pays en voie de développement (PVD). Elles constituent les sources principales de la création d’emplois et génèrent des ressources importantes pour leurs promoteurs. Elles contribuent aussi de manière non négligeable à la formation du produit intérieur brut (PIB) dans les PVD. L’accès au financement est alors un défi crucial à leur création et à leur développement. Malgré leur rôle indéniable dans le développement socioéconomique, elles accèdent toujours difficilement au financement bancaire, et ce, en dépit des politiques publiques de soutien menées à leur égard. Cette thèse vise à analyser les facteurs explicatifs du faible financement des microentreprises (ME) dans le cas du Burundi. Les données que nous avons exploitées dans cette thèse proviennent des deux bases. Celle issue des données collectées sur 3430 dossiers de crédits des institutions de microfinance (IMF) burundaises et celle réalisée auprès de 223 microentrepreneurs à partir d’une enquête. A l’aide du modèle probit, l’analyse économétrique a révélé que certaines caractéristiques des microentreprises et/ou de leurs promoteurs comme l’âge du microentrepreneur, la durée du crédit sollicité, la zone d’implantation de la microentreprise influent négativement sur l’accès au financement. D’autres caractéristiques telles que la nature de la garantie présentée, le profil du microentrepreneur ou son niveau de richesse jouent positivement sur le financement des microentreprises. L’étude a montré aussi que la microfinance reste un moyen efficace pour financer les microentreprises. Ainsi, la restructuration des fonds de garantie et l’engagement accru du gouvernement surtout en matière d’accompagnement sur le terrain améliorerait le financement des microentreprises.

📄 Agriculture is an important pillar of the national economy of Burundi. The sector contributes more than 40 % of gross domestic product (GDP) and employs 90 % of the population. The main challenges facing the sector include soil degradation, loss of biodiversity, water contamination, pesticide residues, use of genetically modified organisms and participation in climate change. Faced with such constraints, the Burundian farmers experience new modes of production and consumption such as the development of agroecological farms (crop association, crop rotation, agroforestry, anti-erosion ditches) and the use of biofertilizers and biopesticides. This study aims to analyse the impact of agro-ecological innovations on agricultural production and environment in Mumirwa region, especially in three communes of Bubanza province (Bubanza, Musigati and Rugazi). The study approach consisted of surveys conducted on two samples (members of cooperatives and non-members), focus groups, individual interviews and field visits. The ordinary least squares method and comparative approach between the two samples (treatment sample and comparison sample) were used to analyse the impact on production and environment, especially on soil fertility. We referred to the ISABU laboratory (Higher Agronomic Institute of Burundi) results of the soil samples brought by ADISCO NGO before and after planting the beans using organic manure on the one hand and chemical fertilizers on the other. The results showed that agro-ecological practices positively impact agricultural production and improve soil fertility. After one year of adoption, bean production increased by 21%. The analysis of the soil samples indicate that the combination of agro-ecological practices improves the soil's chemical characteristics, contributing to increased productivity. This could be explained by the fact that the development of agro-ecological farms and biofertilizers promote the sedimentation of particles of organic matter from runoff water and organic manure

📄 This article aims to identify the determinants of financing microenterprises in Burundi by microfinance institutions. Using the logit model and exploiting data from the loan portfolios of Burundian microfinance institutions, the econometric analysis reveals that the financing of microenterprises in Burundi is strongly correlated with characteristics of these and/or those of their micro-entrepreneurs on one hand, and to the nature of the guarantee presented when applying for credit on the other hand. We conclude by saying that the consolidation of public financial support, the establishment of monitoring policies for these guarantee funds, and the involvement of all stakeholders could substantially improve the financing of microenterprises in Burundi.

📄 cet article identifie les déterminants de financement des micreontreprises agricoles au Burundi. A partir des données issues des portefeuilles des institutions de microfinance au Burundi portant sur le financement des microenterprises agricoles et à l'aide du modèle économétrique logit, les résultats révèlent que certains facteurs empêchent les IMF de financer plus efficacement des petites exploitations familiales agricoles. parme ces facteurs, nous pouvons mentionner le manque de garantie de la part des microentrepreneurs, les besoins financiers exprimés par l'exploitant agricole, le faible organisation des exploitants agricoles en groupement solidaire, la nature de l'activité agricole à financer

📄 La mise en évidence des principaux facteurs déterminants le risque de liquidité dans les banques commerciales burundaises à caractère local avec une expérience d’au moins 15 ans, est l’objectif principal de cet article. A l’aide des données de panel, une analyse économétrique a été faite. Les résultats empiriques prouvent que six variables sur sept testées constituent les principaux déterminants du risque de liquidité des banques étudiées. Il s’agit de la rentabilité des actifs, des écarts de liquidité, du chiffre d’affaires, de la rentabilité des fonds propres, de la capitalisation bancaire et de la taille de la banque. La rentabilité des actifs et les écarts de liquidité ont des effets positifs tandis que ces autres facteurs influencent négativement le risque de liquidité bancaire. L’inflation quant à elle n’a montré aucune influence.

📄 L'objectif de cet article est d'identifier d'une part, les facteurs explicatifs du faible financement des microentreprises par les IMF et d'autre part, les facteurs explicatifs de la faible utilisation des produits financiers des IMF par les microentreprises. En utilisant le modèle probit et à partir des données d'une enquête réalisée auprès de 221 microentrepreneurs clients des IMF au Burundi, les résultats économétriques révelent que certaines caractéristiques des microentrepreneurs les empêchent à utiliser plus intensément les microcrédits des IMF. Parmi ces facteurs, nous pouvons citer par exemple la nature de l'hypothèque, l'âge de l'entrepreneurs, et d'autres empêchent les IMF à financer les microentrerises comme la nature du projet à financer, le niveau de formation de l'entrepreneur, le profil de celui-ci. D'autres facteurs encore sont pris en compte non seulement au moment de la demande d'un prêt, mais aussi dans le cas de l'accès. C'est le cas du niveau de richesse de l'entrepreneur.
