| 53. | Where there is sufficient data on past substitution, it may be possible to derive quantitative measures on the substitutability of different products. For example, it may be possible to derive diversion ratios between candidate substitute products. Diversion ratios estimate the share of sales volumes lost by the product of interest that is diverted to each candidate substitute product in response to changes in relative supply conditions. In addition, it may be possible to estimate own-price elasticities and cross-price elasticities (80) for the demand of a product using econometric techniques (81) (82). In order to be reliable, such quantitative evidence must be sufficiently robust.
