This is especially relevant for Southern Africa and, as such, the Southern African Development Community (SADC) has a set agenda regarding regional integration goals, and where the guiding principle is tax harmonisation that benefits all members through tax reform efforts. An understanding of the main determinants of corporate tax (CT) rates, whether internal public needs or external competitive pressure, becomes pertinent. A recent announcement of a global minimum corporate tax rate of 15 per cent holds promise in reducing harmful tax competition and profit shifting and therefore sustainable revenue for all governments concerned. 2022-07-18T00:00:00Z https://ir.unisa.ac.za/handle/10500/29512 Global Corporate Tax Change and the Impact on Southern Africa: Advancing Pluralist Thinking in Economics Robinson, Zurika Corporate tax systems of developing countries can potentially be contributors or impediments to their economic development.

This is especially relevant in the SADC region that has a set agenda regarding regional integration goals, and where the guiding principle is tax harmonisation that benefits all members through tax reform efforts. Despite the importance of the topic, empirical literature remains scant, and this paper attempted to revisit the CIT determinants in the SADC region. Having a larger database at their disposal, the authors could update the existing empirical literature. The sample period of the study included the commodity booms and slumps following the global financial crises, and illustrated the varying fortunes of developing countries in general, and the SADC specifically. Furthermore, given the lower economic growth, together with the variable commodity prices since 2008, there is a concern that corporate tax revenue may continue to erode. A cross-section panel was utilised to determine those factors that may best explain changes in corporate taxes in Southern Africa over the period of time from 1980 to 2017.

The study employed the augmented mean group procedure, which accounts for country-specific heterogeneity and cross-sectional dependence, and the Granger non-causality test to test for causality in the presence of cross-sectional dependence. The results show that (1) The impact of financial sector development on domestic investment depends on the measure of financial sector development utilised; (2) Domestic credit to the private sector has a positive but insignificant impact on domestic investment in ECOWAS, whereas banking intermediation efficiency (i.e., ability of the banks to transform deposits into credit) and broad money supply negatively and significant influence domestic investment; (3) Cross-country differences exist in the impact of financial sector development on domestic investment in the selected ECOWAS countries; and (4) Domestic credit to the private sector Granger causes domestic investment in ECOWAS. The study recommends careful consideration in the measure of financial development that is utilised as a policy instrument to foster domestic investment. We also highlight the importance of employing country-specific domestic investment policies to avoid blanket policy measures. Domestic credit to the private sector should be given priority when forecasting domestic investment into the future. 2020-08-31T00:00:00Z
