This paper investigates the determinants of tax revenue performance in all 15 Southern African Development Community countries during 1990-2010, using panel data. The investigation makes use of two estimation techniques in testing for country specificity. These are the least squares dummy variables fixed effects and the feasible generalised least squares by Park (1967) and Kmenta (1986). The extreme-bound analysis technique is also used in delineating the various causal relationships (including a sensitivity analysis).
This paper investigates the effect of tax harmonisation on foreign direct investment (FDI) in the Southern African Development Community (SADC) region. Findings of a first attempt to investigate the linkage between taxation (tax rates and policy) and FDI (in all 15 countries), using an eclectic panel data modeling approach from 1990-2010 are presented.
