Researching different price points can be difficult. Assuming a modest degree of interest in the
product, it is in the respondent's self interest to make a case for the least expensive price. None
of the most popular methods for researching price points effectively address this issue for any one respondent.
- Open-ended questions that simply ask the respondent to name a "fair" price for the product
will inevitably leave money on the table. We estimate that underpricing by this model typically exceeds 50%.
- Fixed price-point questions that present a respondent with multiple price points and inquire about
interest in the product at each price point will, if administered via mail, systematically over-represent
the lowest price point. Somewhat greater control of the situation can be maintained if a telephone survey
is conducted, but even there a reasonably intelligent respondent will deduce the pattern of the questions
and will attempt to lowball the price. This is true regardless of whether the price starts at the
lowest point and works upward, or at the highest point and works downward, or if prices are randomly presented.
MRA's Solution:
As a general rule, we prefer to use a quasi-experimental design and test different price points across unique
groups of respondents, with each respondent seeing and evaluating one - and only one - unique price
point. Determining the optimal price point is accomplished by comparing across the different groups as
opposed to comparing across different questions for one larger group. The key benefit of this approach is that
each respondent sees only one price point. The questionnaire is thus simplified and the respondent has no inherent
self-interest in trying to lowball the survey data.
