Abstract

Our study addresses the issue of tax design and rent-sharing for the main copper-producing countries in Africa and Latin America. We use an original database to construct our mining tax policy indicator, and combine it with four other databases to study its determinants. The de jure average effective tax rate (AETR) is calculated with a discounted cash-flow model applied to a representative copper mine under each country-year tax regime. We then estimate pooled ordinary least squares models with year fixed effects and heteroskedasticity-robust standard errors. We pay particular attention to forms of governance, the broader political context and political party affiliation, to explain mining tax policies. Our main results indicate that democratic regimes are more likely to capture a larger share of the rent compared to autocratic ones. Beyond regime type, the institutional setting itself plays a critical role in shaping rent distribution, as does transparency. Evidence also suggests that left-wing governments capture a larger share of the rent compared to right-wing ones. Finally, these findings contribute to the social anthropology literature on ‘travelling models’, which are designed by international experts based on supposedly universal mechanisms.

Abstract

In order to finance their various development programmes, revenue mobilisation has become one of the major challenges facing African countries in general, and Benin in particular. The aim of this paper is to analyse the impact of governance on tax revenue in Benin. In theory, good governance is supposed to promote an improvement in the level of revenue mobilisation. This hypothesis is tested empirically using secondary data from the World Bank covering the period from 1970 to 2023. The results obtained using the dynamic approach based on the error-correction model showed that economic and political governance have a positive impact on tax revenue mobilisation in Benin. Furthermore, institutional governance does not currently appear to have an impact on revenue mobilisation, which could be explained by the persistent weakness of this indicator throughout the period analysed.

Abstract

One of the challenges of successful decentralisation is the local administrations’ ability to efficiently mobilise tax revenue. This paper aims to analyse the convergence of municipal administrations’ tax effort in Benin. To address this issue, the paper uses a three-stage stochastic frontier model developed by Kumbhakar et al (2014) on the one hand, and on the other hand, a dispersion analysis was carried out. The data used are panel data from Benin’s seventy-seven (77) municipalities over the period from 2008 to 2020; they are drawn from the statistics of Benin’s National Commission for Local Finances (CONAFIL). The results show that the temporary tax effort (TER) accounts for 67.5%, the permanent tax effort (KHTE) accounts for 25.4%, and the average overall tax effort (OTE) for Benin’s municipalities accounts for 17.3%. Furthermore, the results show that there is little convergence in tax effort amongst municipalities. Finally, it is observed that resource transfers received by municipalities, population density and the municipality’s status have a significant negative impact on the municipalities’ tax effort. These results suggest the need to strengthen both the quantity and quality of staff. Performance criteria should be introduced for access to central Government grants, and experience-sharing between municipalities in terms of tax collection strategies.

Abstract

This study analyzes the Taxation of the Digital Economy (TED), identifies the main challenges faced by the Mozambican Tax System (SFM) (2023–2025), examines the relevance of the connecting factors to TED, and proposes improvements to the SFM to ensure tax fairness and prevent competitive asymmetries. A mixed-methods approach was used–qualitative, descriptive, and exploratory–through semi-structured interviews with two Mozambican Tax Authority (AT) officers. Content analysis was applied; for the quantitative component, an online questionnaire was administered to 163 individuals, and statistical analyses were used (descriptive statistics, Chi-square Test, Student’s T-test, ANOVA, principal component analysis, cluster analysis, and discriminant analysis). The results revealed limited tax collection capacity due to gaps in legislation, a lack of connection criteria, insufficient technological integration, and difficulties in tracking cross-border digital transactions, despite the growth of the digital economy (EcD) in Mozambique. It is concluded that reforms are needed in the SFM for cross-border digital taxation, to strengthen technology in tax administration, and to implement international cooperation strategies. The study contributes to the literature on cross-border digital taxation in African contexts and offers practical implications for the formulation of tax policies in Mozambique.
