Abstract
Elasticities of substitution were estimated to determine how easily consumers switch from one carbohydrate product to another by using a translog function and the dual approach. Results indicate that carbohydrate pairs are substitutional in behaviour, which supports the observed interdependence between carbohydrates.
Elastisiteite van substitusie is bereken ten einde te bepaal hoe maklik verbruikers van een stysel na 'n ander verander deur gebruikmaking van 'n getransformeerde logaritmiese funksie en die duale benadering. Resultate toon dat koolhidraatpare substitute is, wat die waargenome interathankheid tussen koolhidrate bevestig.
