The share of corporate saving in total saving in South Africa has increased during the past four decades. In this dissertation various economic theories are examined in order to try to explain this change and to determine the possible implications of this change. The conclusion is that the relationship between the investment decision of companies and their savings decision is governed by the determinants of the financing choice of firms. These include cost, risk, control and availability. If, because of these factors, firms prefer to finance investment with retained earnings, there is a relationship between investment and the level of corporate saving. The degree to which the investment decision is dependent on the availability of internal financing will determine the importance of the level of corporate saving in a country. / Oor die afgelope vier dekades het die aandeel van maatskapybesparing in die totale besparing in Suid-Afika toegeneem. In hiersie vehandeling word veskillende ekonomiese teoriee ondersoek ten einde hierdie verandering te probeer veklaar en te probeer vasstel wat die implikasies van hierdie veandering is. Die gevolgtrekking waartoe gekom word, is dat die verband tussen die investeringsbeleid en die maatskappye se besparingsbesluit bepaal word deur faktore wat die finansieringskeuse van die firmas beinvloed, naamlik koste, risiko, beheer en beskikbaarheid. Indien hierdie faktore daartoe lei dat die maatskapye verkies om investering met terruggehoue bespaaring the finansier, is daar 'n verband tussen investering en die vlak van maatskappybesparing. Die mate waarin die investeringsbesluit afhanklik is van die beskikbaarheid van interne finansiering, sal bepaal hoe belangrik die vlak van maatskappybesparing in 'n land is. / Economics and Management Sciences / M.Com.

Various studies conclude that accelerated economic growth and development are necessary in South Africa to make a significant contribution towards reducing high levels of unemployment, inequality and poverty. Moreover, in theories of economic growth the export sector is frequently accorded a special role in encouraging faster economic growth, which is often supported by empirical evidence. Nonetheless, a question that remains unresolved is whether higher export growth leads to higher economic growth in South Africa and what particular role exports may play within the overall economic growth process of the country. This study applies Johansen’s cointegration procedure, impulse response functions, variance decomposition analysis and Granger causality tests to shed light on the channels through which export growth may impact South Africa’s economic growth rate. Quarterly time series data ranging from 1975q1 to 2012q4 is employed in the study’s empirical tests. The empirical results lend support to the idea that the role of exports in the economic growth process fundamentally lies in their ability to encourage investment and capital formation. While export growth supports higher economic growth in the short-run, it does not have the same effect in the long-run. Nonetheless, with export growth supporting faster capital formation in South Africa, and capital formation, in turn, significantly increasing economic growth in the long-run, the impetus to growth stemming from exports has been found to lie in the channel to capital formation. On the basis of the empirical results, not only are exports a critical requirement of higher investment, but they are also anticipated to play a prominent role in lifting the balance of payments constraint that would make investment-led growth possible in the first place. Overall, a strategy of export-led growth that does not explicitly emphasise the export-capital-growth connection is likely to fall short of reflecting the dynamics contained within the exports-growth relationship in South Africa.

The neoclassical theory suggests that free flows of external capital should be equilibrating and thereby facilitating smoothening of an economy's consumption or production patterns. South Africa has a very low savings rate, making it highly dependent on capital inflows which create instability and volatility in global markets. A policy dilemma is undoubtedly evident: capital inflows help to cater for the domestic low savings and at the same time the inflows pose instability, a threat on competitiveness and volatility challenges to the same economy due to their impact on exchange rates. The question is: are all forms of capital flows equally destabilizing? Since studies based on South Africa considered only the relationship between aggregate capital flows and real exchange rate, modelling individual components of capital flows could enlighten policy formulation even further. The composition of the flows and their effects on the composition of aggregate demand determine the evolution of real exchange rate response to surges in capital flows. Through co-integration and vector error correction modelling techniques applied to South African data between 1990 and 2010, the study found out that foreign portfolio investment exerts the greatest appreciation effect on the South African real exchange rate, followed by other investment and finally foreign direct investment. Thus the impact of capital flows on real exchange rate in South Africa differs by type of capital. This presents varied policy implications.

This study examined the impact of real exchange rates on economic growth in South Africa. The study used quarterly time series data for the period of 1994 to 2010. The Johansen cointegration and vector error correction model was used to determine the impact of real exchange on economic growth in South Africa. The explanatory variables in this study were real exchange rates, real interest rates, money supply, trade openness and gross fixed capital formation. Results from this study revealed that real exchange rates, gross fixed capital formation and real interest rates have a positive long run impact on economic growth, while money supply and trade openness have a negative long run impact on economic growth in South Africa. From the regression results, it was noted that undervaluation of the currency significantly hampers growth in the long run, whilst it significantly enhances economic growth in the short run. As such, the policy of depreciating the exchange rates to achieve higher growth rates is only effective in the short run and is not sustainable in the long run. Based on the findings of this study, the researcher recommended that misalignment (overvaluation and undervaluation) of the currency should be avoided at all costs. In addition, the results of the study showed that interest rates also have a significant impact on growth and since interest rates have a bearing on the exchange rate, it was recommended that the current monetary policy in South Africa should be maintained.

This thesis object with functioning of present retirement system in the Czech republic and in selected countries. There are described differences of financing and differences of pillars on which are this systems built. Further are in this thesis answered reasons for reforming of this systems. The goal of this thesis is design expert system used to serve to financial advisers for suitable saving product selection according to client requests.
