Given the growing acceptance of cashback offers (e.g. $10 PayPal cashback within 24 hours of the transaction) among retailers, this paper aims to understand how consumers evaluate them vis-à-vis traditional price-discounts and their subsequent impact on retailers’ promotional strategies.

Six experimental studies examine if and when consumers can discern differences in the time-of-reward-accrual (i.e. the waiting time associated with receiving promotional savings) of cashbacks and price-discounts. Building on evaluability theory, we propose that the time-of-reward-accrual of promotion is hard-to-evaluate. Put simply, consumers find it hard to assess the duration of waiting time associated with receiving promotions. Consequently, consumers’ perceptions of cashbacks vis-à-vis price-discounts can be influenced by whether they evaluate both promotions simultaneously [joint-evaluation (JE) mode] or independently [single-evaluation (SE) mode].

The initial four studies show that the time-of-reward-accrual of promotions is hard-to-evaluate. Cashbacks appear just as appealing as price-discounts when consumers evaluate them independently (SE-mode) but lose their appeal when consumers view them alongside price-discounts (JE-mode). The next two studies further enhance the generalizability of our findings by replicating the observed effects for different purchase types (hedonic vs utilitarian) and varying promotional benefit levels (high vs low).

By shedding light on evaluations of time-of-reward-accrual of promotion, this paper adds a new dimension to research on promotions. The paper also extends the application of evaluability theory beyond domains such as hiring, fairness judgments and product bundle assessments. The paper presents evaluation mode as a boundary condition to explain contradictory predictions from prior research for consumers’ preferences for delayed vs immediate promotions.

Develop a comprehensive framework for assessing the knowledge organization systems (KOSs), including the taxonomy of Wikipedia and the ontologies of Wikidata, with a specific focus on enhancing management and retrieval with a gender nonbinary perspective.

This study employs heuristic and inspection methods to assess Wikipedia’s KOS, ensuring compliance with international standards. It evaluates the efficiency of retrieving non-masculine gender-related articles using the Catalan Wikipedian category scheme, identifying limitations. Additionally, a novel assessment of Wikidata ontologies examines their structure and coverage of gender-related properties, comparing them to Wikipedia’s taxonomy for advantages and enhancements.

This study evaluates Wikipedia’s taxonomy and Wikidata’s ontologies, establishing evaluation criteria for gender-based categorization and exploring their structural effectiveness. The evaluation process suggests that Wikidata ontologies may offer a viable solution to address Wikipedia’s categorization challenges.

The assessment of Wikipedia categories (taxonomy) based on KOS standards leads to the conclusion that there is ample room for improvement, not only in matters concerning gender identity but also in the overall KOS to enhance search and retrieval for users. These findings bear relevance for the design of tools to support information retrieval on knowledge-rich websites, as they assist users in exploring topics and concepts.

This study aims to help understand individual donors’ preferences over different designs of humanitarian–business partnerships in managing humanitarian operations and to help understand if donors’ preferences align with their actual donation behavior.

Choice-based conjoint analysis was used to understand donation preferences for partnership designs, and a donation experiment was performed using real money to understand the alignment of donors’ preferences with actual donation behavior.

The results show that partnering with the business sector can be a valuable asset for humanitarian organizations in attracting individual donors if these partnerships are managed well in terms of partnership strategy, partnership history and partnership report and disclosure. In particular, the study finds that the donation of services and products from businesses corporations to humanitarian organizations are preferable to individual donors, rather than cash. Furthermore, donors’ preferences are not necessarily aligned with actual donation behavior.

The results highlight the importance of presenting objective data on projects to individual donors. The results also show that donors value the provision of services and products by business corporations to humanitarian operations.

Partnerships between humanitarian organizations and business corporations are important for the success of humanitarian operations. However, little is known about which partnership designs are most preferable to individual donors and have the biggest chance of being supported financially.
