New Applications for Consumer
Research
The tools of consumer research, which were originally
developed for use in marketing, have many other applications
in litigation and business consulting. With proper design
and execution, surveys and experiments can shed light on a
wide variety of important questions. Among the areas in
which these tools may be valuable are the investigation of
claims of false advertising, the consideration of possible
trademark and brand infringement, antitrust market
definition, and new product launch strategy.
When investigating possible false advertising, consumer
research methods can be valuable in addressing issues of
deception and materiality. Surveys and experiments can be
employed to identify deception through the analysis of
advertising interpretation, and to determine the materiality
of deceptive advertising through analysis of consumer
behavioral intentions. For example, researchers could
conduct an experiment involving the following steps: 1)
measure the product category preferences of each individual
consumer participating in the experiment, 2) show half of
the subjects the original advertisement with the alleged
deceptive content, 3) show the other half of the subjects a
"corrected" advertisement that is identical to the original
advertisement except that the alleged deceptive content has
been removed, and 4) have the subjects answer questions that
measure their understanding and perceptions of the
advertisement and their behavioral intentions. Differences
in the responses of the two groups of subjects could be
attributed to the alleged deceptive content in the original
advertisement.
Surveys and experiments can be useful when considering
possible trademark or brand name infringement. Controlled
experiments are useful in measuring brand confusion and
estimating damages. Through recognition, recall, and
elaboration exercises, researchers can evaluate the impact
of trademark infringement and identify potential
disproportionate effects on heterogeneous consumers. Assume
that brand B is allegedly infringing on brand A's trademark.
An experiment could confirm or reject the existence of brand
confusion and determine whether certain customer
characteristics make brand confusion more or less likely.
For example, the experiment may find that heavy category
users are less likely to be affected by the trademark
infringement than light category users, or that high
education consumers are less affected than low education
consumers. Determining which users are most likely to be
affected by infringement may have important implications for
the estimation of damages.
Consumer research can also aid in market definition.
Researchers can design experiments and surveys to help
define the product market and the geographic market.
Experiments, such as conjoint analysis, can determine the
extent to which specific products are substitutes, and
surveys can give consumers the opportunity to list products
that they consider similar to the focal product. In conjoint
analysis, consumers are shown a series of cards, each
listing the attributes of a particular product. Certain
products are very similar, differing along only one
dimension. Through a ranking task or a repeated choice
exercise, consumers reveal their preference for the
different product attributes. Conjoint analysis has also
been used to estimate consumers' reactions to changes in
price. In that way, conjoit analysis can be used to estimate
the price elasticity of demand for a product, which can be
used in market definition.
Surveys also may be useful in market definition. Surveys
can collect demographic information on customers, such as
zip code, and the resulting data on the geographic
distribution of stores' customers can be used to define
geographic markets. Such surveys may be particularly useful
if stores do not collect individual customer data at the
time of purchase. The importance of conducting statistically
reliable surveys for the purpose of market definition is
highlighted in FTC v. Whole Foods, in which the
judge disregarded survey research due to potential biases
from poor sampling methodology, questionnaire design, and
response rate.
In formulating a new product launch strategy, the firm
would like to gather information on consumers' perceptions
of the new product versus its competitors. Focus groups can
be assembled to compare test versions of the new product
with competing products. In later stages of product
development, focus groups can supply the firm with valuable
information on optimal launch timing and promotion strategy.
If the product is at the concept stage, however, and no
prototype is available, conjoint analysis can be used to
determine the importance of different product attributes to
consumers.
Surveys and experiments of consumer research collect both
quantitative and qualitative data, and its techniques enable
researchers to combine both types of data. For example,
content analysis allows the researcher to statistically
analyze qualitative data by assigning quantitative scores to
the language used in open-ended answers. Content analysis
software can identify and categorize the emotions and
opinions expressed in written passages. Well-designed
surveys and experiments can provide researchers with
high-quality data that can be used in econometric models for
purposes such as calculating damages and forecasting demand.
Consumer research's comprehensive approach to data can be
useful in addressing a wide variety of difficult questions.
