HUMAN CARBOHYDRATE DEMAND IN SOUTH AFRICA / Die menslike vraag na koolhidrate in Suid-Afrika

Abstract

This note discusses aspects of carbohydrate consumption, prices of carbohydrates and interdependence in the carbohydrate market. Knowledge gained is used to analyse the effects of relative prices and income on the consumption of different carbohydrates in South Africa. Price and income elasticities of demand estimated by the traditional single equation approach and a systems method do not differ markedly. However, because of the interdependence between carbohydrate consumption, the systems method seems to be more appropriate than the traditional single equation approach. Relative prices of carbohydrates and income per capita play a major role in influencing the consumption of different carbohydrates.

Hierdie referaat bespreek aspekte van styselverbruik, pryse van stysels en intera fhanklikheid in die koolhidnatmark. Kennis ingewin is gebruik om die effek van pryse op die verbruik van koolhidrate in Suid-Afrika te ontleed. Elastisiteite verkry met behulp van die tradisionele enkelvergelyking benadering en 'n sisteembenadering verskil nie betekenisvol nie. Die gebruik van 'n sisteembenadering eerder as 'n enkelvergelyking benadering is egter meer korrek vanweëd die interafhanklikheid tussen koolhidrate. Relatiewe pryse en per capita inkomste speel 'n deurslaggewcnde rol in die bepaling van die verbruik van koolhidrate.
