Improving Customer Compatibility with Tradeoff Transparency

The Effect of Payment Transparency on Consumption: Quasi-Experiments from the Field

Recent research suggests that the method of making a payment can influence the willingness to pay and consumption behavior. In this manuscript, we argue that payment mechanisms differ from each other along the dimensions of transparency, and that the degree of transparency correlates positively with the pain of paying using the mechanism, and negatively with consumption and spending. We replicate previous experimental results using quasi-experiments from the field, and find that the lower the payment transparency, the greater is the consumption. However, this effect is weak for products whose consumption rates are inflexible.

What else can your payment card do? Multifunctionality of payment modes can reduce payment transparency

Payment modes (e.g., cash vs. credit card) vary in the transparency of the outflow of money. Smartcards (multifunctional cards), which bundle payment with non-payment functions (e.g., loyalty programs, identification, and other information functions), have become an increasingly popular payment mode. This shift toward multifunctionality in payment modes is assumed to reduce payment transparency and consequently to decrease consumers’ recall accuracy of past expenditures. We employ a field study to examine recall accuracy for recent purchases with cash, a single-function card, and a multifunctional card. We find that recall accuracy is lower when using a single- or a multifunction card than cash. We also find that it is not the multifunctionality of the card that results in a higher recall error but the individual usage patterns: A higher usage frequency of the non-payment functions results in a higher recall error.

Do Payment Mechanisms Change the Way Consumers Perceive Products?

Do Customers Learn from Experience? Evidence from Retail Banking

We study customers' adoption and subsequent switching decisions with regard to a menu of three-part tariff plans offered by a commercial bank. Using a rich panel data set covering 70,510 fee-based checking accounts over 30 months, before and after the introduction of the plans, we find that most customers adopt non-cost-minimizing plans, preferring plans with large monthly allowances and high fixed payments. Furthermore, after adoption, customers who exceed their allowances and consequently pay overage fees are more likely to switch to plans with larger allowances than customers who do not experience such fees. Notably, after switching, these overage-paying customers pay higher monthly payments than before. In contrast, switching customers who did not pay overage payments before switching pay less after switching. Our findings, unlike those of previous research on experience-based learning, suggest that the behavior of experienced customers does not converge to the predictions of neoclassical models. We propose that “overage aversion,” which is closely related to loss aversion and mental accounting, is the most plausible explanation for our findings.

Minimum Payments Alter Debt Repayment Strategies Across Multiple Cards

U.S. households currently hold $770 billion in credit card debt, often managing repayments across multiple accounts. The authors investigate how minimum payment requirements (i.e., the requirement to allocate at least some money to each account with a balance) alter consumers’ allocation strategies across multiple accounts. Across four experiments, they find that minimum payment requirements cause consumers to increase dispersion (i.e., spread their repayments more evenly) across accounts. The authors term this change in strategy “the dispersion effect of minimum payments” and provide evidence that it can be costly for consumers. They find that the effect is partially driven by the tendency for consumers to interpret minimum payment requirements as recommendations to pay more than the minimum amount. While the presence of the minimum payment requirement is unlikely to change, the authors propose that marketers and policy makers can influence the effects of minimum payments on dispersion by altering the way that information is displayed to consumers. Specifically, they investigate five distinct information displays and find that choice of display can either exaggerate or minimize dispersion and corresponding costs. They discuss implications for consumers, policy makers, and firms, with a particular focus on ways to improve consumer financial well-being.

“Repayment-by-Purchase” Increases Consumer Debt Repayment

This article tests the effect of a novel credit card payment format—repayment-by-purchase—on consumers’ payments toward credit card debt. In contrast to typical balance repayment, where consumers make repayments relative to a total amount owed, repayment-by-purchase prompts consumers to select items (e.g., a Starbucks coffee) or categories of purchase (e.g., restaurant and café purchases) and to make payments toward their related debt. A field experiment first suggests that customers who opted into repayment-by-purchase paid 12.18% more toward their statement balance than a control group. Subsequently, five lab experiments show that consumers repaying-by-purchase increase repayment by an average of 22.47% over typical balance repayment. Process evidence suggests that these differences may be driven by repayment-by-purchase's power to increase purchase salience, which in turns increases perceptions of progress toward reducing debt. Consistent with this theory, the effect of repayment-by-purchase on bill repayment emerges regardless of whether consumers repay durable versus nondurable goods, and for specific items or categories of purchases, as long as the bill uses labels that are concrete enough to raise past purchase salience.

Information disclosure and credit card repayments: evidence from Malaysia

Purpose This study analyzes the role of information disclosure in influencing credit card repayments by focusing on three intervention methods for improving repayment decisions among credit cardholders. Design/methodology/approach This study uses the survey method to collect data. Four questionnaires are designed to identify which types of disclosure elicit better repayment decisions among credit cardholders. The participants were approached using the mall intercept method, and a total of 1,775 responses were obtained. Findings Estimations using means comparison tests show that not providing minimum payment information improves repayments. The expected benefits are not delivered by the provision of higher minimum payment information or additional information that highlights the negative effects of making the minimum repayment only. Further analysis using logit estimation reconfirms the benefit of not providing minimum payment information. However, when such information is given, low minimum payment information elicits better repayment decisions than high minimum payment information or additional information. Repayment worsens under the additional information condition compared to the high minimum payment condition. Research limitations/implications The findings of this study have a bearing on the decisions of policy makers, credit card issuers and consumers. Originality/value This paper clarifies the role of information in improving debt repayment decisions.

How Do Consumers Avoid Penalty Fees? Evidence from Credit Cards

Using data from multiple card issuers, we show that the most common penalty fee type incurred by credit card holders, late payment fees, declines sharply over the first few months of card life. This phenomenon is wholly due to some consumers adopting automatic payments after a late payment event, thereby insuring themselves against future late payment fees. Nonadopters, who remain on manual-only payments, experience an unchanged high likelihood of future fees, despite exhibiting ample levels of available liquidity. Our results show that heterogeneity in adopting account management features of financial products, such as automatic payments, is important for understanding who avoids financial mistakes.

Purchase Justifiability Drives Payment Choice: Consumers Pay with Card to Remember and Cash to Forget

AbstractAlthough consumers often have multiple payment methods at their fingertips, such as cash and credit/debit cards, prior research is silent on how consumers choose between them. We home in on a key element of purchase—purchase justifiability—that affects how consumers choose to pay. Analysis of 118,042 real-world purchases and six experiments reveals that when consumers are motivated to forget (vs. remember) a purchase because they see it as difficult (vs. easy) to justify, they have an increased preference to pay with cash (vs. card) because cards create a “paper/electronic trail” that aids memory retrieval. These payment preferences are strongest among consumers most likely to recall/track their card spending, and manifest only when card expenses are trackable. We reconcile our results with the classic effect of payment method on pain of paying and discuss implications for merchants and for financial institutions designing payment methods of the future.

Always Leave Home Without It: A Further Investigation of the Credit-Card Effect on Willingness to Pay

In studies involving genuine transactions of potentially high value we show that willingness-to-pay can be increased when customers are instructed to use a credit card rather than cash. The effect may be large (up to 100%) and it appears unlikely that it arises due solely to liquidity constraints. In addition to demonstrating the effect, we provide a methodology for detecting it, and our findings suggest a source of variance to test alternative explanations.

Disclosure: Psychology Changes Everything

We review literature examining the effects of laws and regulations that require public disclosure of information. These requirements are most sensibly imposed in situations characterized by misaligned incentives and asymmetric information between, for example, a buyer and seller or an advisor and advisee. We review the economic literature relevant to such disclosure and then discuss how different psychological factors complicate, and in some cases radically change, the economic predictions. For example, limited attention, motivated attention, and biased assessments of probability on the part of information recipients can significantly diminish, or even reverse, the intended effects of disclosure requirements. In many cases, disclosure does not much affect the recipients of the information but does significantly affect the behavior of the providers, sometimes for the better and sometimes for the worse. We review research suggesting that simplified disclosure, standardized disclosure, vivid disclosure, and social comparison information can all be used to enhance the effectiveness of disclosure policies.

Disclosing the costs of co-holding liquid assets and high-interest debt has limited impact on behavior

Abstract Why do consumers simultaneously maintain low-yield liquid assets and high-interest revolving debt? This behavior, known as ``co-holding,'' affects 23\% of credit card users in our sample from a major international bank and costs the typical co-holder hundreds of dollars annually in unnecessary interest charges. Our analysis of 38 months of detailed banking records reveals that co-holding is remarkably persistent, with typical co-holders maintaining this behavior for most months observed. Our analysis also reveals that co-holding is not a static financial position: co-holders regularly deposit and withdraw from asset accounts while simultaneously making new credit card purchases. To test whether co-holding could be addressed through information disclosure, we conducted a large-scale field experiment (n = 125,328), providing clear information about co-holding behavior and its costs. Customers received targeted messages through their bank's mobile app, where they could easily transfer money from assets to pay down debt. Despite sufficient power to detect economically small effects, we found no meaningful changes in debt repayment amount, though customers did respond in other ways---making more frequent repayments and paying above required minimums. These results challenge explanations based on limited attention or information gaps and suggest that simple information disclosure, even when carefully designed and delivered through trusted channels, may not effectively address costly financial behaviors.

The moderating role of income on consumers’ preferences and usage for online and offline payment methods

In this paper we examine consumer attitudes towards a payment method, which is a key factor affecting the probability of completing a transaction offline and online. More specifically, we constructed a model that surveyed the offline and online usage of prepaid e-cash, debit cards, credit cards and cash. User perceptions of the attractiveness of e-cash and various traditional payment means were also empirically assessed. Consumer attitudes towards a payment technology were found to be influential on users’ perceptions in both online and offline environments. User perceptions of offline purchases with a payment technology had significant and positive effects on the corresponding online usage perceptions. The effects of our research model are contingent on the income level of users. Our findings have significant implications, as they could help shed light on why consumers abandon their shopping carts and do not complete their transactions, which could potentially play a significant role when it comes to designing applications targeting sspecific consumer segments.
