Does Greater Amount of Information Always Bolster Attitudinal Resistance?

Previous research suggests that attitudinal resistance to information that challenges a prior evaluation increases with the amount of information underlying the prior evaluation. We revisit this proposition in a context in which a set of important claims about a target brand are presented either alone—a lower amount of isolated information—or along with other favorable, but less important claims—a higher amount of embedded information. Results from two experiments show that when the challenge occurs immediately after the initial evaluation, a greater amount of embedded initial information does produce greater attitudinal resistance. However, when the challenge occurs after a delay, a lesser amount of isolated information produces greater attitudinal resistance. The findings qualify previous assumptions about the role of prior information in attitudinal resistance, and support a constructive view of judgment revision and attitudinal resistance.     

The effect of physical possession on preference for product warranty

Peck and Shu (2009) found that touching a product causes greater endowment effect. We seek to replicate and extend this finding to the case that whether touching a product consumers have just bought may increase the willingness to pay (WTP) for warranty. Loss aversion, the tendency to prefer avoiding losses over obtaining equivalent monetary gains, often explains product warranty purchases. This tendency will be stronger when the buyers consider the product as part of their endowment. Touching the product promotes stronger ownership perception and thus shifts consumer's reference point. The new reference point causes consumers to anticipate greater pain from the loss of the product and thus leads to higher WTP for product warranty protection. We find support for this hypothesis in two field studies with a total of 104 participants.     

Consumer Control and Empowerment: A Primer

This paper introduces consumer empowerment as a promising research area. Going beyond lay wisdom that more control is always better, we outline several hypotheses concerning (a) the factors that influence the perception of empowerment, and (b) the consequences of greater control and the subjective experience of empowerment on consumer satisfaction and confidence.     

Vehicle ownership and usage charges

We present a simple model to study the welfare effects of a shift from ownership to usage taxes for cars. We consider a model in which a single representative consumer derives utility from consuming two goods—consumption of motor vehicle kilometers, and an aggregate consumption good treated as numeraire. We characterize the optimal consumption of car kilometers by a representative car user and find that a shift from ownership towards usage taxes is not necessarily welfare-improving: while a revenue-neutral shift makes the representative car user worse off; a utility-neutral shift leads to a significant loss of revenue to the government. An empirical analysis based on Singapore data is also consistent with our theoretical results.     

The Piecemeal Approach to Comparative Advertising

When attempting to portray the attractiveness of a brand vis-à-vis its competitors, an ad may make global claims about superiority or specific claims about one or more attributes. A special case of latter is the piecemeal ad in which the advertised brand is compared to a competitor on one attribute, a different competitor on a second attribute, another competitor on a third attribute, and so on. The present research demonstrates the effectiveness of this technique and explores the parameters of its influence. We find that piecemeal messages are persuasive because they make seemingly strong claims in a believable manner. Consumer skepticism appears to arise only when conditions for scrutiny are very favorable.
