The impact of jump bidding in online auctions

This paper reports findings of two field studies, conducted on a local online auction website, that compare bidding strategies in charity and non-charity auctions, focusing on the extent of jump bidding at different stages of auctions. Results indicate that jump bidding is negatively correlated with bidder entry and positively associated with ending prices. These correlations are greatest during the beginning stage of auctions and are substantially larger for charity auctions than for non-charity auctions. Additionally, early-stage jump bidding occurred more often in charity auctions (consistent with bidders trying to drive up prices in charity auctions), ending-stage jump bidding was more frequent in non-charity auctions (possibly used strategically to win the auction). Further, frivolous products tended to sell at a higher proportion of retail value in charity auctions, providing a replication of the results of previous researchers but in a field setting.     

Opposites attract: Impact of background color on effectiveness of emotional charity appeals

The present work utilizes research on context effects and color psychology to investigate how background color can enhance the effectiveness of positive and negative charity appeals. Five experiments measuring both actual donations and donation intention examine the hypothesis that a negative charity appeal against an orange (vs. blue) background and a positive charity appeal against a blue (vs. orange) background will increase donations. We propose that this is because blue and orange colors are incongruous with positive and negative charity appeals, respectively, due to the affective valences of the appeals and the perceptions of warmth and coldness cued by the background colors. This incongruity enhances the attention people pay to the charity appeals, thereby strengthening their emotional response to the appeals, which increases charitable donations. When attention is manipulated, people who pay a high (vs. low) level of attention to the charity appeal are more likely to donate regardless of the color and valence of the appeal, suggesting attention is an important antecedent to the intensity of the emotional response and subsequent donation behavior. We also identify affect diagnosticity as a boundary condition for the effect – when people are informed that color affects their emotions, the contextual effect of color disappears.     

How donor's regulatory focus changes the effectiveness of a sadness-evoking charity appeal

Past research offers conflicting findings on whether sadness-evoking charity appeals help solicit a donation. To reconcile these findings, we introduce prospective donors' regulatory focus as a moderator for understanding when and why sadness appeals motivate or demotivate giving. Specifically, we propose that the sense of helplessness or loss of control associated with sadness appeals increases donors' sensitivity to advertiser's manipulative persuasion tactics, as those tactics can threaten donors' control over their donation decision. As a result, sadness appeals are more likely to activate persuasion knowledge among prevention- (vs. promotion-) oriented donors who tend to be vigilant against manipulative persuasion attempts. Across six main studies and two supplementary studies, we find that a prevention (vs. promotion) focus discourages charitable giving when it is solicited using a sadness appeal, whereas regulatory focus does not affect the giving when other emotion appeals (e.g., happiness appeal or guilt appeal) are used. We find that a prevention (vs. promotion) focus demotivates donation solicited by a sadness appeal because it activates persuasion knowledge that evaluates solicitor's motive behind the sadness appeal, resulting in increased skepticism, dampened feelings of sympathy, and consequently, reduced charitable giving. However, when persuasion knowledge is deactivated (e.g., when donors' cognitive capacity is constrained or the soliciting charity has a reliable reputation), regulatory focus no longer affects donor skepticism, sympathy, and charitable giving, even when a sadness appeal is used to call for donation.     

The message in the box: how exposure to money affects charitable giving

Does donation box transparency matter in regard to donation behavior? The purpose of this research is to test the effect of donation box transparency on potential donors’ charitable behavior. In a series of experimental studies, including a field experiment, data were collected on willingness to donate and donation amount in three treatments: a wooden donation box (opaque condition), transparent donation box containing very little money, and transparent box almost full of money. Participants in the transparent box treatment were both less willing to donate money and they donated less money compared to subjects in the opaque box treatment. Moreover, data was collected to demonstrate that participants in the transparent box conditions experienced a heightened state of self-sufficiency due to the effect of money exposure. Implications are discussed for theory development and future research avenues and in terms of practical considerations for charity organizations.     

Corporate Giving Behavior and Decision-Maker Social Consciousness

This paper investigates why some companies give to charity and others do not. The study uncovers a strong relationship between the personal attitudes of the charitable decision maker and the firm's giving behavior. This relationship indicates that the human element of personal attitudes may interact and play a very important role in a firm's decision to become involved with philanthropic activities. The study also shows that firms who have a history of giving to charity cite altruistic motives for their behavior. On the other hand, firms that do not give to charity tend to use business reasons to explain their non-involvement.     

Encouraging Charitable Donations via Charity Gift Cards: A Self-Determination Theoretical Account

Charities seeking to increase donations are now offering charity gift cards (CGCs), which allow recipients to select how their gift card is allocated across various charitable projects. Supporting a model derived from self-determination theory, an experiment shows that U.S. consumers are more satisfied and more likely to donate to the card-sponsoring charity after using a CGC than after learning a donation has been made in their name, because CGCs enhance consumers’ felt autonomy, competence, and relationship with the charity and its projects, which predict a more charitable self-concept and satisfaction with the gift. Theoretical and managerial implications are discussed.     

Guilt Regulation: The Relative Effects of Altruistic Versus Egoistic Appeals for Charity Advertising

This article examines how egoistic (versus altruistic) appeals in charity advertising help regulate guilt and result in more favorable ad attitudes and donation intentions. The proposed affect forecasting and regulation model depicts the process by which guilt states are mitigated more effectively by egoistic appeals, because they strengthen the affect forecasting belief that giving to charity leads to happiness. Such enhanced affect forecasting beliefs further improve ad attitudes, which lead to greater donation intentions. This research tests the proposed model by exploring three possible types of guilt: existing guilt (Study 1), integral guilt (Study 2), and incidental guilt (Study 3).     

Experts and Amateurs: The Role of Experience in Internet Auctions

The use of auctions as a pricing mechanism has grown dramatically over the last few years. The introduction of electronic auctions has significantly widened the pool of consumers who participate in auctions and increased the number of companies attempting to sell their products in an auction format. Previous empirical research on auctions has focused almost exclusively on the behavior of professional bidders in high stakes common value auctions or the behavior of students in laboratory experiments. We collect data on a large number of electronic auctions, across four product categories, to explore the behavior of consumers bidding in a real marketplace. In particular, we focus on the role experience plays in their bidding behavior to uncover whether consumer learning drives the bidding process towards outcomes described in the theoretical literature on auctions. We find that experience does indeed lead to behavior which is more consistent with theory although the proportion of experienced bidders who behave in a manner inconsistent with theory remains quite large.     

A Network Bidder Behavior Model in Online Auctions: A Case of Fine Art Auctions

The marketing literature provides a solid understanding of auctions regarding final sales prices and many aspects of the processes that unfold to result in those outcomes. This research complements those perspectives by first presenting a new bidder behavior model that shows the role of emergent network ties among bidders on the auction outcome. Dyadic ties are identified as the bid and counter-bid patterns of interactions between bidders that unfold throughout the duration of an auction. These structures are modeled using network analyses, which enables: (1) a richer understanding of detailed auction processes, both within auctions and across auctions of multiple lots, (2) a mapping of the processes to the forecast of prices and the trajectory toward final sales prices, (3) the clear and early identification of key bidders who are influential to the bidding action and who impact final auction sales prices, and (4) the results clearly show that the network exchange patterns are significant and contribute to an understanding of auction processes and outcomes above and beyond simple economic predictors such as the number of bids or bidders or the bidders’ economic status. We conclude by providing some managerial implications for online auction houses and bidders.     

To donate or not to donate? Product characteristics and framing effects of cause‐related marketing on consumer purchase behavior

The present study examines potential influences associated with donation framing, product price, product type, and donation magnitude on cause‐related marketing (CRM) campaigns, where money is donated to a charity each time a consumer makes a pur‐chase. In addition to the main effects of the aforementioned factors, experimental results indicate that beneficial effects of product type (i.e., frivolous products bundled with a cause are more effective than practical ones) occur when donation information is framed in absolute dollar terms. The effects of donation framing are found insignificant when the donation magnitude is high. Influences of donation magnitude on CRM effectiveness are limited in high‐priced items. When the donation magnitude is constant, a donation amount framed in absolute dollar value is more effective than that in percentage terms for low‐priced products, and the opposite is true for high‐priced items. In practice, marketers thus stand to gain not only by matching the donation magnitude in their advertised products with the right price but also by an appropriate “framing” of the offered bundles. © 2008 Wiley Periodicals, Inc.     

Strategic Bidding for Multiple Units in Simultaneous and Sequential Auctions

A buyer in an electronic marketplace may be interested in buying a bundle of items, where any one item in the bundle may not be of particular interest. The emergence of online auctions allow such users to obtain bundles by bidding on different simultaneous or sequentially run auctions. Because the number of auctions and the number of combinations to form the bundles may be large, the bundle bidding problem becomes intractable and the user is likely to make sub-optimal decision given time constraints and information overload. We believe that an automated agent that takes user preferences and budgetary constraints and can strategically bid on behalf of a user can significantly enhance user profit and satisfaction. Our first step to developing such an agent is to consider bundles containing many units of a single item to be bought from auctions that sell only multiple units of one item type. We assume that users obtain goods over several days. Expectations of auctions and their outcome in the future allow the agent to bid strategically on currently open auctions. We present an expected utility based strategy to decide how many items to bid for in the current auctions, and the maximum price to bid for each item. We evaluate our proposed strategy in different configurations by varying the number of items sold per auction, number of concurrently running auctions, expected closing prices, etc. We simulate several multiple unit English auctions per day, over multiple days, where most of the bidders bid their true utilities drawn from a distribution. The strategic bidding agent has knowledge of this distribution and uses it to determine its bids. A strategic agent who looks farther ahead into the future produces larger returns when there are few strategic bidders. We also evaluate the effect of risk attitudes on the relative performance of the bidders.     

Charitable organizations' storytelling influence on donors' emotions and intentions

The stories told by charitable organizations are typically designed to take the consumer through different emotional stages. This research probes the view that following exposure to the inciting incident or problem statement in the appeal for a particular charity, the consumer feels negative emotions. These feelings convert into anticipated positive emotions when the consumer is given the opportunity to help the person in need through a donation. Feedback that donors receive from the charitable organization will help to strengthen the emotional pay-off and enhances future donation intentions. The research utilizes an experimental design and data from 319 undergraduate students in a large U.S. university to confirm these hypotheses. Theoretical and managerial implications are then presented.     

Ascending Combinatorial Auctions with Risk Averse Bidders

Ascending combinatorial auctions are being used in an increasing number of spectrum sales worldwide, as well as in other multi-item markets in procurement and logistics. Much research has focused on pricing and payment rules in such ascending auctions. However, recent game-theoretical research has shown that such auctions can even lead to inefficient perfect Bayesian equilibria with risk-neutral bidders. There is a fundamental free-rider problem without a simple solution, raising the question whether ascending combinatorial auctions can be expected to be efficient in the field. Risk aversion is arguably a significant driver of bidding behavior in high-stakes auctions. We analyze the impact of risk aversion on equilibrium bidding strategies and efficiency in a threshold problem with one global and several local bidders. Due to the underlying free-rider problem, the impact of risk-aversion on equilibrium bidding strategies of local bidders is not obvious. We characterize the necessary and sufficient conditions for the perfect Bayesian equilibria of the ascending auction mechanism to have the local bidders to drop at the reserve price. Interestingly, in spite of the free-riding opportunities of local bidders, risk-aversion reduces the scope of the non-bidding equilibrium. The results help explain the high efficiency of ascending combinatorial auctions observed in the lab.     

Auction Fever! How Time Pressure and Social Competition Affect Bidders’ Arousal and Bids in Retail Auctions

Auction sites on the Internet frequently put bidders under time pressure or highlight the social competition that is inherent to auctions. Both aspects are believed to elicit an exciting shopping experience, which may culminate in auction fever. In two laboratory experiments, we investigate the process of auction fever in retail auctions and demonstrate when and how auction fever affects bidding behavior. In contrast to previous studies, we employ physiological measurements as an objective and continuous assessment of bidders’ arousal in addition to a subjective assessment of bidders’ emotions through psychometric scales. Moreover, we explicitly study the interaction of time pressure and social competition on arousal and bids. We find that bidders’ arousal is increased in high time pressure auctions and that this leads to higher bids in ascending auctions—but only when bidders compete with human opponents. Thus, social competition is the actual driver underlying the auction fever phenomenon. Furthermore, we show that the “joy of winning” is significantly stronger than the “frustration of losing” in ascending auctions. Finally, we discuss the implications of our findings for the design of retail auctions.

Does Vice Make Nice? The Viability and Virtuousness of Charity Lotteries

ABSTRACT

Globally, charities are under increasing pressure to find alternative sources of funding. Although charitable gaming has long been considered a viable source of revenue for charities, opponents of gaming have raised concerns about the potential negative consequences associated with gambling. The current paper examines a unique form of charity gaming–the charity super lottery (CSL)–that offers a number of fund-raising benefits to cash-strapped charities. Results from a preliminary study of CSL ticket buyers suggest that the CSL may be both a virtuous and viable source of fundraising. Interviews revealed that CSL consumers (1) viewed the ticket purchase as a donation rather than gambling, (2) were unlikely to be involved in other forms of gambling, and finally (3) perceived the CSL purchase as a complementary rather than supplementary form of charity support behavior. Implications for the fundraisers of charitable organizations and directions for future research are discussed.     

Factors Influencing Monetary Donations to Charitable Organizations

ABSTRACT

Charitable organizations are under increasing financial pressure to attract and retain private donors. However, research examining consumer attitudes toward and motivations for giving to charity have yielded ambiguous results. A cross-disciplinary literature review suggests individual donation behavior is based on several factors including attitudes toward helping others, attitudes toward the charitable organization and various intrapersonal, social and economic motives. Using exploratory factor analysis seven factors are identified which influence monetary donations to charitable organizations. Of these seven factors, two factors measure attitudes relevant to charitable giving and five factors capture motivations for charitable giving. These measures are important to academicians, policy makers and practitioners in the development of theory and marketing strategy.     

Charitable Donations as Social Exchange or Agapic Action on the Internet: The Case of Hungersite.com

SUMMARY

Donations to charity have long been of interest to marketing academics seeking to understand the relationships between nonprofit organizations and their customers. A key area of concern is that of motivation-why do individuals donate time, money and other resources to charities in general or to particular charities? While marketers in particular, and social scientists in general, have explained donation and gift giving in terms of the exchange paradigm, more recently consumer researchers have introduced the notion of agapic (or unselfish) behavior to explain some aspects of gift giving. Using the case of a successful charitable Internet site, Hungersite.com, this paper attempts to contrast the exchange and agapic paradigms of donation behavior, with the re sulting strategic implications this may have for charity marketing strategy.     

Vettes and lemons on eBay

This paper empirically tests whether there are asymmetric information problems in the market for used Chevrolet Corvettes sold on eBay. The first test is based on a result from Akerlof (Quarterly Journal of Economics, 1970). If there is asymmetric information in the used market, bidders should place a premium on a new Corvette, all else equal. The paper finds little systematic evidence of a new car premium. The second test is based on a result from Bajari and Hortacsu (Rand Journal of Economics 34(2):329–355, 2003). If there is asymmetric information, then bidders will prefer to bid late in the auction in order to conceal their private information from other bidders. The paper fails to find evidence of more late bidding on used Corvettes relative to new Corvettes. The third test is based on the idea that if there is asymmetric information then there may be a winner’s curse problem in these auctions. The paper fails to find evidence consistent with bidders avoiding the winner’s curse. The results are not consistent with asymmetric information problems in the market for used Corvettes sold on eBay. It is not clear however, whether this result generalizes to other cars sold on eBay or cars sold in the off-line market.     

Promoting charitable donation campaigns on social media

It is salient to investigate how to increase persuasiveness of donation campaign messages communicated on social media. The purpose of this paper is to propose that a construal fit between different message frames (loss/gain framing and desirability/feasibility framing) and donation temporal proximity enhances the persuasiveness of charity donation messages. A convenience sample of 120 adults in Izmir voluntarily participated in this study and participants were randomly assigned to one of four experimental conditions. This research shows that gain-framed donation-promoting messages paired with desirability-framed messages are more effective on distant-future donation intentions, whereas loss-framed messages paired with feasibility-framed messages are more effective on near-future donation intentions. The findings of this paper are to figure out ways to enable marketers to develop effective Corporate Social Responsibility strategies for telecommunication service companies to encourage consumers’ charitable donations in a social media context.
