Using data from 40 Sub-Saharan African (SSA) countries from 1980 to 2015, the present study examines the effects of globalization and its dimensions on economic growth by distinguishing the de jure and de facto aspects. Through second-generation panel data tests, the study analyzes the crosssectional dependence between the countries studied and adopts an appropriate methodology for its effectiveness treatment. The study finds an economic growth effect for the overall globalization in SSA countries. It also demonstrates that de jure globalization increases economic growth, while de facto aspect undermines this growth. However, this is still evidence that de jure, de facto economic globalization, and de jure social globalization promote economic growth. De facto social globalization and de jure political globalization remain ineffective, while de facto political dimension of globalization hinders growth.

Using data on Sub-Saharan African countries and over the period from 1980 to 2017, this study empirically investigates the effects of economic globalization on public debt. By disentangling between the de jure and de facto aspects, the study uses second-generation panel data tests to diagnose the cross-sectional dependence, unit root and cointegration. The cross-sectional error correction model with the estimation by dynamic common correlated effect technique, is used. We find that economic globalization as a whole increases the public debt in the short run while decreases it in the long run. For its dimensions, we show that financial globalization increases the public debt in the short and long run, while trade globalization increases the public debt in the short run but decreases it in the long run. Consideration of the de jure and de facto aspects of economic globalization shows that the de jure economic globalization does not influence government debt while its trade dimension reduces the short-run public debt and its financial dimension increases the long-run public debt. The de facto economic globalization and its dimensions increase public debt in the short run, while in the long run only the de facto trade globalization belittles the public debt.

The study analyses the effect of global value chains participation (GVCP) on CO2 emissions and assesses whether digitalization technologies can enhance environmental quality. We use panel data estimation techniques for 112 developing countries over the period 1990–2018. Findings show that the GVCP contributes to environmental degradation. Other factors that increase environmental damage include FDI inflows, industrial value‐added and electricity consumption. However, renewable energy consumption significantly reduces CO2 emissions. Findings show that digitalization is an effective channel in reducing CO2 emissions in the GVCP in developing countries. These findings have important policy implications in exploring the GVCP's development dynamics in upgrading opportunities from digital technologies to reduce environmental pollution and promote sustainable growth in developing economies.
