Effects of infrastructures on environmental quality contingent on trade openness and governance dynamics in Africa

The African Continental Free Trade Area and Financial Development for Women Economic Participation in Africa

“…This implies that there is a threshold of financial depth above which the unconditional negative effect of intra-African trade integration is completely nullified. The narrative on the computation of thresholds in interactive regressions in order to provide room of more policy implications is consistent with extant interactive regressions literature (Nchofoung & Asongu, 2022a, 2022b. Furthermore, in order for the computed threshold to be policy-relevant and make economic sense, the attendant threshold should be situated within the range (minimum to maximum values) provided in the summary statistics.…”

Inclusive Education and Health Performance in Sub Saharan Africa

“…The GMM addresses the potential problem of endogeneity through an instrumentation technique. This problem is addressed by accounting for the concern of reverse causality and time-invariant omitted variables (Nchofoung, 2022 ; Nchofoung & Asongu, 2022 ). The GMM technique is a robust technique that accounts for the error term related problems.…”

“…(2) The study adopted a data set structured in a panel form for 48 African countries between 2000 and 2020. The GMM is a widely used strategy for panel analysis which takes care of cross-country variation since they are inherent in panel analyses (Baum et al, 2003 ; Kouladoum et al, 2022 ; Nchofoung & Asongu, 2022 ). (3) Thirdly, there is a high correlation between health performance variables and their first lags.…”

Microfinance Institutions and Female Entrepreneurship in Sub-Saharan Africa: Avoidable Female Unemployment Thresholds

“…In order to achieve the goals of this study, as articulated in the introduction and hypothesized in Section 2, thresholds are computed in the light of contemporary interactive regressions literature (Nchofoung & Asongu, 2022a, 2022bNchofoung et al, 2022). Such thresholds are important in order to address the concern of multicollinearity, as documented in Brambor et al (2006) on the pitfalls of interactive regressions.…”
