The Gabor Granger model for identifying the optimum price of a product is suitable under two specific conditions:

1. Your company already has firm ideas about the price of the product.
2. It can be assumed that the target group has only vague ideas about an adequate price for the product. This can be the case, for example, with newly introduced products, or with products that are purchased very rarely.

In contrast to the Price Sensitivity Meter from Van Westendorp, with the Gabor Granger model, various price points are established and the respondents say whether they would buy the product presented at the relevant price. If the start price is not accepted, then the price is reduced until a price is accepted or until the minimum price point has been reached.

Alternatively, the respondent can be presented with a mid-range price as a start price, and if that is accepted then the price rises or, if rejected, is reduced, until the respondent refuses or accepts it. However, the respondents grasp the principle of the rising and falling prices relatively quickly, and thus try to either avoid higher prices and/or achieve lower prices by answering strategically.
