The authors hypothesize that when managers integrate two projections to form a sales estimate, they evoke and use a sales range to judge inappropriately the plausibility of each projection. This judged plausibility, as well as the "margin of error" (based on the market research company's typical accuracy), is used to assign weights to each projection. Five experiments find strong evidence for this process and demonstrate a resulting bias.

The authors propose and test a new "polyhedral" choice-based conjoint analysis question-design method that adapts each respondent's choice sets on the basis of previous answers by that respondent. Polyhedral "interior-point" algorithms design questions that quickly reduce the sets of partworths that are consistent with the respondent’s choices. To identify domains in which individual adaptation is promising (and domains in which it is not), the authors evaluate the performance of polyhedral choice-based conjoint analysis methods with Monte Carlo experiments.

It is increasingly apparent that the financial value of a firm depends on intangible assets (e.g., brands, customers, employees, knowledge) that are not on the balance sheet. In this paper, we focus on the most critical aspect of a firm—its customers. Specifically, we demonstrate how valuing customers makes it feasible to value firms, including high growth firms with negative earnings.
