My study investigates whether the effects of non-cash incentives on employee performance depend on when the incentive is paid and what type of task is being performed. Although firms frequently use non-cash incentives, such as merchandise, travel awards and gift cards, the effects of non-cash incentives, relative to cash incentives, are not well understood by researchers. Drawing on economic and psychology theories, I predict that the effects of incentive type (cash or non-cash) on performance depend on incentive payoff timing (near or distant future) and task type (analytic or creative). Specifically, for an analytic task, I predict and find that a cash incentive paid in the near future is most effective. For a creative task, I predict and find that a cash incentive paid in the near future and a non-cash incentive paid in the distant future are most effective. The results of my study should benefit theory and practice by identifying the most effective combination of incentive type and payoff timing for a given task type.

Die bestaande belastingaansporingsmaatreels in Suid-Afrika is nagevors. Belastingaansporingsmaatreels wat vroeer in gebruik was, is ook ondersoek. Aandag is gegee aan die kontantaansporingsmaatreels wat vir vervaardigingsondernemings beskikbaar is in Suid-Afrika. Programme wat deur onder andere die Nywerheid-Ontwikkelingskorporasie van Suid-Afrika Beperk en die Kleinsake-Ontwikkelingskorporasie aangebied word is ondersoek. Ondersoek is ingestel na die bevindings van die Margo kommissie Verslag wat in 1986 uitgereik is. Die verslag van die Katz-kommissie wat in 1994 uitgereik is, is ook nagevors. Aandag is gegee aan die 1994, 1995 en 1996 begrotings asook sommige van die aspekte van die Algemene Ooreenkoms op Tariewe en Handel. Die belastingkoerse en aansporingsmaatreelsprogramme wat deur die Verenigde State van Amerika, Verenigde Koninkryk en Kanada beskikbaar gestel word aan ondernemings is ondersoek. Moontlike oplossings vir die probleme wat tans ondervind word in SuidAfrika se aansporingsmaatreelstelsel is geformuleer. / The existing tax incentives in South Africa were researched. Tax incentives that were previously in use, were also investigated. Attention was given to the cash incentives available to manufacturing enterprises in South Africa. Amongst others the programmes offered by the Industrial Development Corporation of South Africa Limited and the Small Business Development Corporation were investigated. The findings of the Margo Commission Report issued in 1986 were investigated. The Katz Report issued in 1994 was also researched. Attention was given to the 1994, 1995 and 1996 budgets as well as some of the aspects of the General Agreement on Tariffs and Trade. The taxation rates and incentive programmes available to enterprises in the United States of America, United Kingdom and Canada were investi gated. Possible solutions for the problems currently experienced in South Africa with regard to incentives have been formulated. / School of Computing / M.Sc (Computer Science)
