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.

Vehicle accidents by means of Public transport annually leads to a large number of passenger deaths and life long disablement. AsDu Toit, Martina Petronella a result, there is a need for preventative measures by identifying the psychomotor abilities of bus drivers during the recruitment and selection process of employment. The study was conducted among 398 bus drivers employed by a large bus company. The Vienna Test Battery was administered. It was found that distance estimation, ability to recognize forms and figures, concentration ability, eye-hand feet coordination and two-hand coordination predicted the effectiveness of bus drivers successfully. It is suggested that further research should focus on client services, attitude of bus drivers and learning potential, as factors that influence the effectiveness of bus drivers. / Industrial psychology / M.A. (Industrial Psychology)
