This study aims to empirically examine the impact of the price structure of two-sided markets on transaction volume and market share (MS) in the context of the Korean credit card industry. The Korean credit card market differs from those in the United States (U.S.) or Europe in terms of transaction structure (i.e. a three-party system in Korea vs a four-party system in the U.S. or Europe) and government policy. In addition to the merchant discount rate and the cardholder annual membership fee rate, the authors included and analyzed exogenous variables to eliminate any endogeneity. Based on the analysis results, the authors found that credit card usage performance (i.e. transaction volume) increases with an increase in the relative price ratio (merchant discount rate ÷ cardholder membership fee rate) paid by merchants and cardholders, provided that the total price (merchant discount rate + cardholder membership fee rate) paid by merchants and cardholders remains constant. Therefore, this study is the first to confirm that the Korean credit card market operated as the theoretical mechanism of a two-sided market during the analysis period. This effect can only be observed in specific cases such as the launch of the so-called “Chief Executive Officer(CEO)-designed card.” When a new CEO takes office in a credit card company and launches a “CEO-designed card,” there is a significant increase in not only card usage performance but MS as well owing to the price structure changes caused by expanding the benefits that customers derive from card use.

The influence of website quality on online compulsive buying behavior (OCBB) in the context of online shopping based on the usage of a credit card (UCC) and online impulsive buying behavior (OIBB) was investigated in this study.

The authors used a research model to examine the relationships between the study components as per the prescription. For this investigation, the authors used an online survey form to obtain primary data from 350 respondents on social media. A covariance-based structural equation modeling approach was used to evaluate the structural research model and data.

The findings reveal that the quality of online shopping websites positively affects consumers' UCC and OIBB, and these in turn positively influence their OCBB.

The study emphasized impacting elements on consumer behavior and gave advice for future research based on the results. Using several dimensions of website quality, this study bridges the knowledge gap between UCC, OIBB and OCBB.

Based on UCC and OIBB, the authors developed a new model to investigate the link between website quality and OCBB. To the best of the authors' knowledge, it is the first experimental result that assesses the impact of website quality on OCBB.

This article describes financial professionals' perceptions of their clients' financial behaviors and the explanatory factors underlying these behaviors.

In this qualitative research, the authors seek to understand financial professionals' experiences in relation to how their clients manage their own finances. The authors conduct and analyze 26 semi-structured interviews with financial professionals from several industries within the financial sector in Canada.

The professionals in this study noted that despite their clients' financial knowledge, several other factors can explain these individuals' financial behaviors. They include psychological factors (such as financial bias, the need for instant gratification, and the lack of awareness regarding the long-term effects of certain types of financial behaviors), financial habits (such as lifestyle, financial planning and lack of discipline) and the financial system's flexibility with respect to debt financing and repayment. These perceptions are categorized according to whether they are related to debt financing or repayment, savings or investments.

By using a qualitative methodology that relies on the perceptions of financial professionals, this study aims to better understand the financial behaviors of individuals and households, and these behaviors' underlying factors. This study's findings could be useful to various stakeholders interested, in one way or another, in financial literacy, such as organizations aiming to strengthen and promote financial literacy, educators, researchers, regulatory bodies of financial institutions and financial advisers.

This study estimates impact of remittances from internal migration on households' use of bank services in Vietnam.

This study uses data from the Vietnam Household Living Standards Survey and the two-stage least squares method (2SLS).

The results show that receiving internal remittance increases households' probability of having bank accounts and using card services. However, these impacts are different between rural and urban areas.

The results of this study reveal the useful role of internal remittance in increasing the probability of households using bank services, thereby enhancing financial inclusion in Vietnam.

Different from the previous studies, the purpose of this paper is to analyse the impact of internal remittance on the use of bank services in Vietnam at the household level. This paper targets internal migration because it is the main type of migration in Vietnam. Besides, to the best of the authors’ knowledge, this research is the first one that compares the role of internal remittance on households' use of bank services in rural and urban areas in Vietnam.

This study is aimed at assessing the information security management practice with a focus on banking card security in selected financial institutions in Ethiopia, using an international information security standard as a benchmark. It is to identify the gaps and recommend best security practices to help financial institutions meet the required security compliance.

Two financial sectors were purposively selected. A total of twenty-five respondents (IT executives and IT staff) were included in the study. Quantitative data was collected using the PCI-DSS (Payment Card Industry Data Security Standard) security standard questionnaire. In addition, observation and document analysis were made.

The result shows that most of the essential security management activities in the financial sectors do not comply with the international security standard. Similarly, the level of most of the indispensable security requirements that should be in place is found to be below the acceptable level. The study also revealed major security factors that prohibit the financial sectors from PCI-DSS security standard compliance.

This study assessed the information security management practice with a focus on banking card security and tried to figure out the limitations of security practices of the organizations surveyed based on the standard adopted. The topic has not been well explored especially in the Ethiopia context. Hence, the result can positively influence security policies, particularly in the banking sector.

The description of “blockchain banking”, the determination of “the sub-processes” of “blockchain banking” as a “business process”, and the assessment of “maturity level” in Parsian Bank.

Theoretical sources on “blockchain banking” were initially investigated. Then the “sub-processes” of “blockchain banking” as a “business process” were extracted by Parsian Bank's experts through the “Delphi method”. Next, the “sequence” of the “sub-processes” was determined by means of the “AHP”. Eventually, Parsian Bank's maturity levels for all the sub-processes as well as the overall maturity level were specified on the basis of the “CMMI” V1.3 in order for Business Process Management (BPM).

Blockchain banking’ combines traditional banking with cryptocurrencies, which can be provided by merging “hybrid e-wallet” with “bank account” and “bank card” – all together as “crypto bank account”. Plus, “hybrid e-wallet” is a form of mobile e-wallet on blockchain that supports both cryptocurrencies and traditional currencies in the same platform by which the purchase and sale of cryptocurrencies are possible. Besides, “Blockchain banking service” can also be offered within the framework of “open banking” aligned with “open innovation” through a FinTech (or a beta bank) in collaboration with a licensed bank via “open API”, which is called “blockchain banking based on FinTech”. At last, the eight sub-processes of “blockchain banking” were determined and Parsian Bank's “maturity level” was specified.

This is the very first practical guide to “blockchain banking service”.

The purpose of this paper is to explore the application of Kafalah in the practice of Islamic banking in Malaysia generally and ascertain applicable rules governing the application under relevant legislations and Shariah. The study also aims to examine the legislations in the light of Shariah provisions governing Kafalah and propose amendments.

This is a qualitative research where primary data sources mainly legislations and secondary sources comprising of articles and books on the subject of Kafalah were examined. It is an exploratory legal research that primarily focuses on library studies and adopts doctrinal approach for content analysis of data from the identified sources.

Kafalah is widely used in Islamic banking in Malaysia with primary or secondary application in structuring such products/services as personal guarantee, bank guarantee, Islamic credit card among others. The substantive law applicable to Kafalah in Islamic banking in Malaysia is the Contracts Act 1950 as decided cases indicate. However, provisions of the Act are at variance with rules of Shariah applicable to Kafalah on absolution of guaranteed debtor, multiple guarantors’ liability towards guaranteed sum as well as recourse and recovery from principal debtor.

This research explored the practice of Kafalah in Islamic banking under Malaysian legal framework based on the available literature. The research does not embody an empirical evaluation.

This research suggests, with respect to the identified issues, an amendment to the Act for clarification as follows: that recourse and recovery from principal debtor is only where creditor has requested guarantor to settle outstanding debt, that presence of surety does not absolve principal debtor from his original liability and that multiple guarantors stand as having equal responsibility towards guaranteed amount. The research findings will assist policy and law makers to harmonize the relevant laws with the Shariah to facilitate sustainable development of Islamic banking.

The purpose of this paper is to evaluate the efficiency in financial intermediation and the cost efficiency in banking service of credit unions in Brazil, based on essentially accounting variables, and to analyze the temporal evolution of the efficiency of these cooperatives.

With a sample of 315 cooperatives over the period from 2007 to 2014, this research uses a two-stage process: application of regression models with panel data to verify which variables are related to the defined outputs, with the reduction of 31 variables to 8 variables in both models; and application of the data envelopment analysis method to obtain an analysis of credit unions’ efficiency.

The results demonstrate a high level of efficiency in financial intermediation, with low variation over time, associated with a low efficiency in the banking service, in which few cooperatives have remained efficient over time. In addition, the cooperatives with highest efficiency in financial intermediation were also the most efficient in providing services.

This research has some limitations about the capacity of the proxies used to capture the real effect of the variables and assumptions of economic relations resulting in restrictions to generalize the results.

Cooperatives are usually analyzed under just one dimension. By separating the analysis into financial intermediation and banking services, cooperatives that are more efficient in each dimension can be identified, in addition to analyzing the evolution over time. The authors found that efficiency tends to be lower in banking services, and few cooperatives remain at the highest level of efficiency over time in both models.

Credit unions provide an important service in the banking and credit market. Therefore, understanding its operation and the characteristics that influence its efficiency allows a better management of the cooperatives themselves and a greater understanding of this important segment of the financial market.

Futurist Jim Dator provides a personal insight of how he “sees” the past, present, and futures of Hawaiian tourism. The paper aims to discuss this issue.

Ian Yeoman interviews one of the world's most prominent and respected futurists, Professor Jim Dator, from the Futures Research Center of the University of Hawaii at Manoa's Political Science Department.

Like a climatologist, futurists discuss long‐term futures which are very uncertain, controversial, and often frightening stories. The past tells how the present occurred. Understanding that story is essential before considering the future. The growth of tourism is a fabulous story dependent on many developments whose future is uncertain. The tourism industry may want a “more of the same” trajectory of continued economic growth but a number changes are on the horizon which Dator calls “The Unholy Trinity,” namely the end of cheap and abundant energy; a profoundly unstable environment and a dysfunctional global economic system. Dator concludes that no government now governs satisfactorily, and so the future of tourism is extremely precarious and uncertain.

The interview provides both insight into how tourism has evolved and foresight of what could occur in the futures. Central to the interview is Dator's identification of the Unholy Trinity, Plus One, that suggests that the future will not neither be like the present nor like the future the tourism industry has hoped for in terms of continued economic growth. The originality and value of Dator's frank views are thought provoking, going beyond present wisdom and comfort.

Ethics is fundamentally a science of social and collective responsibility. Ethics concerns human behavior as responsible or accountable. Because of the nature of social interaction, certain members of the society will bear greater authority, and hence, greater individual and social responsibility than others. In our world, personal responsibility and social responsibility are hardly separable. Personal responsibility becomes responsibility for the world because the person and the world are inseparable. In this chapter, we use the term responsibility from a legal, ethical, moral, and spiritual (LEMS) standpoint as some promise, commitment, obligation, sanctioned by self, morals, law, or society, to do good, and if harm results, to repair harm done on another. Hence, responsibility from a moral perspective is trustworthiness and dependability of the agent in some enterprise. Its inverse is exoneration – the extent to which one is excused from commitment and repairing the harm done to others by one’s actions. We apply the theories and constructs of executive responsibility to two contemporary cases: (1) India’s Super Rich in 2014 and (2) the Fall and Rise of Starbucks. After exploring the basic notion of responsibility, we present a discussion on the nature and obligation of corporate responsibility into three parts: Part I: Classical Understanding and Discussion on Corporate Responsibility; Part II: Contemporary Understanding and Discussion on Corporate Responsibility, and Part III: A synthesis of classical and contemporary views of responsibility and their applications to corporate executive responsibility.
