    An analysis of the effectiveness of inflation targeting monetary policy framework in South Africa
    (Journal of Economics, Management and Trade, 2019) Sheefeni, J. P. S.; Makuvaza, Leonard; Nyambe, Jacob M.
    This study is premised on investigating the effectiveness of inflation targeting in South Africa. The methods of analysis include the Vector Autoregressive model (VAR), the unit root test and cointegration test. The analysis was conducted with the use of EViews version 9. The findings from the study revealed that the response of inflation is not consistent with the Taylor rule hence increases in the repo rate meant to reduce inflation actually increase the inflationary pressures in the economy. This is due to the composition of the Consumer Price Index. Housing constitutes the largest weight on the CPI hence this has an impact on how the Repo rate affects inflation. The autoregression model of inflation showed that the sum of the coefficients is less than one (0.965) showing that inflation targeting has effectively reduced the persistence of inflation in South Africa. Thus monetary framework in South Africa seems to be effective and should thus be advanced for wider economic benefit.

    Revenue productivity of the tax system in Namibia: Tax buoyancy estimation approach
    (2019) Sheefeni, J. P. S.; Shikongo, A; Kakujaha-Matundu, O
    Buoyancy refers to how tax revenue responds to a gross domestic product without correcting for discretionary alterations in the tax system. The paper assessed the buoyancy of Namibia’s overall tax system in an attempt to measure the response of the tax system in entirety because of fluctuations in the national income and/or the deliberate act by the government to increase tax rate, reviewed tax code and tax machinery etc. The study employed the Engle-Granger approach to the error correction model to estimate the tax buoyancy for the period 2001 to 2014. The empirical findings from the study revealed that overall the Namibian tax system is income inelastic and not buoyant. This is confirmed by a low and negative value of 0.036 which is less than unit. Thus, the economy is not generating sufficient revenue both through discretionary tax measure and through the expansion in the economic activities. Therefore, the government need to introduce measures that will allow for more tax revenue collection to have a stable revenue base. This also means the government need to keep track of tax mobilization with growth in the gross domestic product as well as to ascertain taxes that are productive.
