© 2020 Elsevier B.V. Imagine that you are a marketer with a good product but mediocre online reviews. When would be the best time to present the review score information to consumers: before the product description, with the product description, or after the product description? In order to answer this question, we carried out three online experiments in which we manipulated the order of information (reviews presented first or last), and timing of information (reviews presented simultaneously with or sequential to the product description). Overall, consumers put more weight on information that was seen most recently, particularly when the product description and review information was presented sequentially and the average review score was relatively low. That is, consumers put more weight on review score information after they had first formed an independent opinion based on the product description. Theoretically, these findings are best explained by an adjustment-based anchoring account. Practically, these findings arm managers with effective tactics regarding the placement of review score information.

The authors tested two interventions to improve retirement savings investment decisions. In an incentive‐compatible experiment, 459 participants engaged in a task simulating their working life. Periodically during the simulation, participants chose between different investment options. The authors examined the effectiveness of a “nudge” by manipulating the default option and the effectiveness of a “signpost” by manipulating the display of a pictograph summarizing the expected return of each option. Participants often followed the default option, particularly when it was “smart” (i.e., became more conservative as retirement approached) and when presented together with dynamic pictographs (i.e., updated each year assuming the investment was held until retirement). Those most likely to make optimal choices (i.e., consistent with the life cycle model) were presented with a smart default or dynamic pictographs. These findings reveal how different choice architecture interventions can be used to positively influence behavior. Retirement funds and regulators can support retirement savings decisions by the provision of smart defaults and better risk information in the form of pictographs.

© 2017 INFORMS. Every attribute can be expressed in multiple ways. For example, car fuel economy can be expressed as fuel efficiency ("miles per gallon"), fuel cost in dollars, or tons of greenhouse gases emitted. Each expression, or "translation," highlights a different aspect of the same attribute. We describe a new mechanism whereby translated attributes can serve as decision "signposts" because they (1) activate otherwise dormant objectives, such as proenvironmental values and goals, and (2) direct the person toward the option that best achieves the activated objective. Across three experiments, we provide evidence for the occurrence of such signpost effects as well as the underlying psychological mechanism. We demonstrate that expressing an attribute such as fuel economy in terms of multiple translations can increase preference for the option that is better aligned with objectives congruent with this attribute (e.g., the more fuel-efficient car for those with proenvironmental attitudes), even when the new information is derivable from other known attributes. We discuss how using translated attributes appropriately can help align a person's choices with their personal objectives.

© 2017, © Emerald Publishing Limited. Purpose: The purpose of this research was to create a brief scale to measure perceived social benefit that would be appropriate for use in future research aiming to explore the role of this variable in determining word-of-mouth (WOM) behaviour. There is evidence that perceived social risk negatively impacts the willingness to share, but the role of perceived social benefit has not yet been explored. Understanding how perceived social risk and benefit interact to determine WOM will inform social marketing campaign design. Design/methodology/approach: This paper outlines two studies: Study 1 was concerned with the development of the perceived social benefit of sharing scale (PSBSS), including the construction of preliminary items and the reliability and discriminant validity of the final scale. Study 2 involved an investigation of the concurrent validity of the PSBSS in relation to the likelihood to share. Findings: Study 1 demonstrated that the perceived social benefit associated with WOM was related to social approval, impression management and social bonding. The results of Study 2 established that scores on the PSBSS predicted self-reported likelihood to engage in both face-to-face WOM and electronic WOM. Originality/value: The PSBSS can be used to examine the role of perceived social benefit, including how the interaction between perceived social risk and benefit determines where, when and with whom people will share WOM.
