The economics of credit cards,debit cards and ATMs: A survey and some new evidence

This paper provides a critical survey of the large and diffuse literature on credit cards, debit cards and ATMs. We argue that because there are still many outstanding issues and questions about the pricing, use and substitutability of these payment mechanisms, that there are significant further opportunities for research in these areas. A large number of questions are examined in this survey, including the pricing of credit cards, the impact of networks on the provision and pricing of ATMs, as well as the tradeoffs that consumers make between different types of payment mechanism, including debit cards, credit cards and ATMs. Importantly, this paper is also amongst the first to provide new evidence on this latter question from bank level data (from Spain). We conclude that point of sale (debit card) and ATM transactions are substitutes, and that ATM surcharges impacts point of sale volume significantly.     

How financial information disclosure affects risk perception. Evidence from Italian investors’ behaviour

This paper investigates how different representations of financial information may be appraised in terms of complexity and usefulness, and how financial disclosure influences individuals’ risk perception. By using a consumer testing analytical approach, we run a survey on a sample of Italian investors: 254 bank customers were submitted 4 different templates, each combining a different typology of data (historical and prospective) and framing (words, numbers and charts) to indicate the same level of risk and return of four real-life financial instruments. Representation formats partially overlap with those mandated by regulators and used within the financial industry. Results show that the perceived riskiness of financial products is affected by the way information is disclosed. Perceived complexity of the financial information disclosure intensifies perception of riskiness of the product solicited. Gender, age, personal traits, behavioural biases and financial knowledge, do also play a role. Overall, given investors’ heterogeneity and behavioural biases, neither simplifying disclosure nor a ‘one-size-fits-all’ approach may be sufficient to ensure correct risk perception and to prevent unbiased investment choices.     

Creative contests: knowledge generation and underlying learning dynamics for idea generation

Due to the heterogeneous nature of the crowd in online crowdsourcing, one key question discussed by academics and practitioners is whether participants are skilled enough to make valuable contributions. This research studies learning processes underlying idea generation in creative contests. Based on qualitative findings triangulating participants’ and brands’ perspectives, we identify six incoming and outgoing user skills which contribute to the development of valuable contributions and determine participation in future contests. Building on three types of brand instructions which emerge from the data, findings show how value is added by the collectivity and two complementary dynamics: (1) social learning and (2) learning from experience. From a managerial perspective, results provide guidance in designing successful crowdsourcing competitions by taking benefit from a multi-competent crowd.     

Ooh,that's sour: An investigation of the role of sour taste and color saturation in consumer temptation avoidance

This paper draws on the theory of embodied cognition to argue that sensory imagery and consumer recall of past experiences of sour tastes inspire sour taste perceptions that trigger facial muscle activation, which in turn leads to temptation avoidance. Across four experiments, we show that physical action need not be performed to elicit temptation avoidance. Moreover, our findings show that the effects of visual gustatory imagery are more pronounced when presented against a visual red background low on color saturation. Interestingly, they are not significant in the presence of a high color saturation background. We also discuss the implications of these findings for sensory marketing, alternative consumer strategies to avoid temptation, and visual brand management in the consumer experience economy.     

Crafting Extraordinary Stories: Decoding Luxury Brand Communications

Advertising is central to creating brand meaning by endowing brands with symbolic values and embedding them within their broader sociocultural context. This study analyzes how the symbolic meaning of luxury brands is constructed in print advertisements. In particular, the study shows how brand communications of luxury brands systematically differ from those of premium and mass-market brands. Through a comparative analysis of thematic and formal characteristics of 208 print advertising campaigns consisting of about 1,700 individual ads from the primary advertising campaigns of four luxury brands, four premium brands, and four mass-market brands, this study identifies three distinguishing factors of luxury brand communication: enrichment, distancing, and abstraction. First, luxury brand advertising enriches the communication content by using more complex campaign templates that make more frequent use of symbolism, rhetorical structures, and storytelling. Second, luxury brand advertising systematically uses distancing techniques, such as temporal, spatial, social, and hypothetical distancing. Third, luxury brand ads use higher-level discourses that allow for different interpretations of brand advertisements. Therefore, this study provides insights into the construction of brand identity in the luxury field, as well as the broader sociocultural construction of luxury and the evolution of its core symbolic constituencies.     

Portfolio optimization in the presence of dependent financial returns with long memory: A copula based approach

In this paper, we seek to examine the effect of the presence of long memory on the dependence structure between financial returns and on portfolio optimization. First, we focus on the dependence structure using copulas. To select the best copula, in addition to the goodness of fit tests, we employ a graphical method based on visual comparison of the fitted copula density and the smoothed copula density estimated by wavelets. Moreover, we check the stability of the copula parameter. The empirical results show that the long memory affects the dependence structure. Second, we analyze the impact of this dependence structure on the optimal portfolio. We propose a new approach based on minimizing the Conditional Value at Risk and assuming that the dependence structure is modeled by the copula parameter. The empirical results show that our approach outperforms the traditional minimizing variance approach, where the dependence structure is represented by the linear correlation coefficient.     

Nonlinear Cointegration Relationships Between Non-Life Insurance Premiums and Financial Markets

The aim of this article is to study the adjustment dynamics of the non-life insurance premium (NLIP) and test its dependence to the financial markets in five countries (Canada, France, Japan, the United Kingdom, and the United States). First, we justify the linkage between the insurance and the financial markets by the underwriting cycle theory and financial models of insurance pricing. Second, we examine the relationship between the NLIP, the interest rate, and the stock price using the recent developments of nonlinear econometrics. We use threshold cointegration models: the switching transition error correction models (STECM). We show that STECM perform better than a linear error correction model (LECM) to reproduce the NLIP dynamics. Our empirical results show that the adjustment of the NLIP in France, Japan, and the United States is rather discontinuous, asymmetrical, and nonlinear. Moreover, we suggest a strong evidence of significant linkages between insurance and financial markets, show two regimes for the NLIP, and find that the NLIP adjustment toward equilibrium is time varying with a convergence speed that varies according to the insurance disequilibrium size.     

Countervailing power? Collusion in markets with decentralized trade

We consider the collective incentives of buyers and sellers to form cartels in markets with decentralized trade and pairwise bargaining. Cartels are coalitions of buyers or sellers that limit market participation and compensate inactive members for their abstention. In stable market outcomes, cartels set Nash equilibrium quantities and cartel memberships are immune to deviations. The set of stable market outcomes is non-empty and its full characterization is provided. Stable market outcomes are of two types: (i) at least one cartel restrains trade and market participation is balanced; (ii) only one cartel is active and it reduces trade slightly below the opponent’s.
