A Markov-Switching Bayesian Vector Autoregression (MS-BVAR) model-based advanced econometric approach is employed to investigate the alignment of economic dynamics and regional cooperation. MS-BVAR analyzes regime changes and cyclical co-movements. The study also examines the impact of trade integration, macroeconomic policy, and institutions on the business cycle synchronization of three Arab Maghreb Union (AMU) countries. The analysis clarifies these secondary objectives to enhance knowledge of economic convergence mechanisms and prevent the dispersion of the study framework. This method links methodology to expected findings, ensuring consistency in interpreting regional economic dynamics. The growth and economic cycles of the AMU countries have shifted. This highlights the structural differences in their economies. Although the AMU exists despite asymmetric shocks, experience demonstrates that such inequalities hinder policy efficacy. Fiscal transfers and coordination are needed to correct structural divergences. North Africa can cooperate, but misaligned economic cycles can cause policy mismatches. Better synchronization reduces costly modifications and makes policy more predictable, improving cooperation. Instead of ruling out collaboration, the study emphasizes adaptive policies that overcome asymmetries.</p>\u0000 </div>","PeriodicalId":47363,"journal":{"name":"African Development Review-Revue Africaine De Developpement","volume":"37 2","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144135617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its importance is further underscored by Sustainable Development Goal 8, which advocates for inclusive and sustainable economic growth, employment, and decent work for all. Achieving inclusive growth requires several key developments, including high institutional quality and a strong insurance industry. This study contributes to knowledge by examining the direct and interactive effects of insurance and institutional quality on inclusive growth. Using the generalised method of moments based on 30 Sub-Saharan African countries between 2005 and 2019, the study presents the following findings: (1) insurance, including life and nonlife penetration, positively impacts inclusive growth; (2) institutional quality, including its components presents a positive influence on inclusive growth; (3) Further, the interaction between insurance and institutional quality stimulates inclusive growth. This implies that quality institutions matter in the drive towards developing the insurance market, thereby fostering inclusive growth. Based on these findings, the study suggests that governments harness insurance's potential to promote inclusive growth and alleviate poverty. Further, the study highlights the urgent need for institutional reforms and policies to unlock the full potential of insurance in driving inclusive growth.

The ordered probit with an endogenous regressor framework has been adopted to analyze the data. This approach addresses the possible endogeneity bias when the ordinal dependent variable and regressor are both endogenous. The major finding reveals that social media use improves the likelihood of high subjective well-being among older African women. This increase is greater for absolute subjective well-being than for relative subjective well-being. In addition, the aforementioned is more pronounced for educated women and those who are satisfied with democracy in their country. However, older women who are victims of corruption and those with a lack of cash income experience a reduction in subjective well-being. It is therefore important that the development of information and communication technology infrastructures and their corollary, social media use, be integrated into public strategies for adapting to the aging population and the resulting social problems.</p>\u0000 </div>","PeriodicalId":47363,"journal":{"name":"African Development Review-Revue Africaine De Developpement","volume":"37 2","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144085108","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this trust is often eroded by economic and social policies that fail to enhance population well-being. This article analyzes how perceptions of living conditions influence trust in tax administration, using data from the Afrobarometer survey (round 8) across 34 African countries. The methodology involves a three-stage approach: descriptive analysis to explore correlations between perceived living conditions and trust in fiscal institutions; multivariate techniques, including Principal Component Analysis and Hierarchical Ascendant Classification, to group countries based on these variables; and ordered probit modeling to assess causality, incorporating control variables such as individual characteristics and addressing endogeneity through an extended ordered probit model. The main findings reveal that poor living conditions negatively impact trust in tax administration, whereas positive perceptions of living conditions enhance trust. This relationship holds across various homogeneous groups, underscoring its robustness. This underscores the need for economic policies that prioritize improving living conditions to build trust in tax administration. Recommended policies include promoting investment and innovation to create jobs and boost incomes; investing in public infrastructure (e.g., roads, schools, and hospitals) to enhance service access and combating corruption to increase transparency and fairness in public administration. These measures could strengthen trust in institutions and improve tax compliance.</p>\u0000 </div>","PeriodicalId":47363,"journal":{"name":"African Development Review-Revue Africaine De Developpement","volume":"37 2","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143889183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Analyzing panel data from 43 SSA countries over 22 years (2000–2021) using the Poisson-Pseudo Maximum Likelihood estimation technique, we find that countries participating in multiple RTAs engage in enhanced bilateral trade within the SSA region. Furthermore, gaining a hub position is positively associated with increased bilateral trade engagement. Our analysis also confirms that network centrality metrics, derived from potential trade connections, are positively related to trade volume. These findings imply that accession to an additional RTA not only creates more opportunities for integration but may also help mitigate politically motivated trade barriers. Moreover, the market access benefits from participating in multiple RTAs appear to outweigh the complexities associated with establishing rules of origin and lengthy trade negotiations. To significantly boost intra-SSA trade and foster deeper regional integration, policymakers in SSA should prioritize aggressively negotiating and implementing RTAs. Moreover, intraregional trade strategies should prioritize systematically securing hub positions within the regional trade network through RTA membership to maximize trade volumes and drive comprehensive regional integration.</p>\u0000 </div>","PeriodicalId":47363,"journal":{"name":"African Development Review-Revue Africaine De Developpement","volume":"37 2","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143852651","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
