This study aims to empirically examine the factors that determine the survival of e-commerce businesses in Korea. In particular, this study focuses on the factors related to the notion of institution-based trust that includes delivery, privacy, and security management. We found that the e-commerce business that does not require extra personal information beyond the standard terms and conditions or provides a feedback mechanism by having an online board to submit a complaint has a higher chance of survival. In addition, the e-commerce business that has a secured web server, shows the specific information about the date of delivery, or provides escrow services is likely to survive longer than others. The research has extended the extant literature on the importance of trust in e-commerce by empirically examining the effects of the institution-based trust factors on the actual survival of e-commerce businesses.

A Mobile App Strategy: An Empirical Study on the Effect of the Mobile Shopping App Usage, Áö½Ä°æ¿µ¿¬±¸, Á¦20±Ç, Á¦4È£, 2019.12

This study aims to broaden our understanding of mobile shopping app usage across competing e-retailers and different channels. We found that a user's prior usage of a specific e-commerce mobile app increases her subsequent usage of its website through a mobile web browser. Thus, mobile apps do not cannibalize the mobile web channel, and there could be a complementary relationship. We also found that a user's usage of competitors’ apps is positively associated with her subsequent usage of a specific e-commerce app. Because many consumers search products and compare prices across multiple e-retailers, having a mobile app helps an e-retailer be exposed to more potential consumers. This study is among the first to study the role of mobile apps in e-commerce by showing the dynamics of cross-channel and cross-vendor usage by a user.

Defining Supply Chain Management: In the Past, Present, and Future, Journal of Business Logistics, Á¦40±Ç, Á¦1È£, 2019.03          

The article titled “Defining Supply Chain Management” published in 2001 in the Journal of Business Logistics has been cited over 4,900 times in the last 17 years. In this paper, we first provide a historical review of how the article originated and the contributions the article made to both the theory and practice of supply chain management (SCM). Next, we highlight the key market and technological changes that have emerged in SCM followed by how the theory proposed in the 2001 article can still be relevant to support SCM research and practice going forward. We also propose ways of configuring a supply chain and partnering across companies to serve customers in an optimal way. We conclude with a call for research on developing new frameworks to better describe, explain, predict, and shed light on the evolving nature of SCM.

Money Well Spent? Operations, Mainstreaming, and Fairness of Fair Trade, Production and Operations Management, Á¦28±Ç, Á¦12È£, 2019.12

We examine the operations, fairness, and social implications of fair trade certified products. We consider the market for fair trade certified products, which may serve as a substitute to a regular product. A fair trade organization chooses standards for the certification, namely, the (unit) premium and minimum fraction of fair trade raw materials, to maximize the total premium transferred to farmers. We analyze the operations of various stakeholders in the fair trade value chain, as well as the role and social welfare of fair trade organizations with different philosophies. We characterize the firms’ entry decision in the fair trade market as well as the resulting market equilibrium. Furthermore, we examine the impact of mainstreaming, i.e., whether to allow large‐scale plantations (often owned by large corporates) to be eligible for fair trade certification or not, which is one of the most discussed topics in the fair trade movement. We also identify the welfare allocation among various stakeholders in the value chain under different certification policies, and thereby address the fairness issue of the fair trade market as well as its resulting social welfare implications. Finally, we obtain a number of policy insights and suggestions to support this nascent marketplace.

Shopping-Life Balance: Towards a Unifying Framework, Technological Forecasting & Social Change, Á¦151±Ç, 2019.12

Highlights This research provides the selection-variation framework to explain technology evolution in latecomer countries. Government's selection force provides a strong signaling effect to attract other entities into collaborative R&D projects. Government research laboratories promotes a fair distribution of results generated from collaborative R&D projects. Abstract In latecomer countries, governments and their research laboratories play an important role in guiding the direction of technology development at the national level. However, the exact mechanism of how these institutional forces influence national collaborative R&D projects remains unclear and understudied. From the selection-variation process perspective of technology evolution, we argue that governments provide a strong signaling effect to attract other entities into collaborative R&D projects. Also through government research laboratories, governments promote a fair distribution of results generated from collaborative R&D projects. In addition, the involvement of diverse entities from industry and academia supplements the fair distribution of results. We provide empirical support for these arguments by analyzing 5, 427 collaborative R&D projects carried out in South Korea among government research laboratories, private firms and universities. A conceptual model is developed and explained in detail to provide the theoretical basis for our arguments, while policy and practical implications are closely examined with a focus on steps that governments can take to guide national collaborative R&D projects.

Product Images Attracting Attention: Eye-tracking Analysis, Asia Pacific Journal of Information Systems, Á¦29±Ç, Á¦4È£, 2019.12       

This study examined the impact of various product photo features on the attention of potential consumers in online apparel retailers’ environment. Recently, the method of apparel’s product photo representation in online shopping stores has been changed a lot from the classic product photos in the early days. In order to investigate if this shift is effective in attracting consumers' attention, we examined the related theory and verified its effect through laboratory experiments. In particular, experiment data was collected and analyzed using eye tracking technology. According to the results of this study, it was shown that the product photos with asymmetry are more attractive than symmetrical photos, well emphasized object within a photo more attractive than partially emphasized, smiling faces are more attractive for customer than emotionless and sad, and photos with uncentered models focus more consumer’s attention than photos with model in the center. These results are expected to help design internet shopping stores to gaze more customers’ attention.

Construal level theory (CLT) have been researched in wide range of disciplines such as marketing, organizational study, psychology, or education. Current study asserts that CLT would explain the effect of different devices of PC and smartphone on interaction between human-computer interfaces and information systems use. In CLT, those who are far from an object in terms of physical, temporal, social or psychological distance, they construe their understanding as abstract (high level) and vice versa. We hypothesized different size of digital device will increase psychological distance and result in behaviors that correspond to present construal level. The analysis result shows that users of PC recognized that they are socially distant from the device and those of smartphone felt that they are socially close to the device. However, the device did not have significant effect on attention to essential information, advertisement preference, and immediacy. The implication to academia, practice and future research and limitations are also discussed.

This study aims to examine the impact of social interactions among users in online games on the continued use of online games, with a focus on competition and cooperation. In particular, we identify interpersonal competitiveness and goal competitiveness as two subfactors of competition and reciprocity and goal interdependence as two subfactors of cooperation. According to the theory of self-determination, the more actions that affect intrinsic motivation, the more humans experience self-deterministic and positive emotions. Perceived enjoyment and sense of accomplishment are considered to be closely related to intrinsic motivation. This study argues that those subfactors of competition and cooperation affect perceived enjoyment and sense of accomplishment, which in turn influence continuance intention through the feeling of flow. Analysis of data collected from an online survey offers empirical evidence for the effects of subfactors of competition and cooperation on perceived enjoyment and sense of accomplishment. We also found that perceived enjoyment and sense of accomplishment affect game users’ continuance intention through the feeling of flow. Our study suggests that game developers should stimulate competition and cooperation among game users so that they can spend more time with their games.

This paper argues that the proper choice and combination of app icon colors are expected to have a positive impact on users’ app icon preference, which in turn influences favorably their intention to download a mobile app. To empirically test the argument, we first extracted the color combinations that match the user 's emotional image for each of the three mobile app categories: keyboard, photo editing, and dating apps. Based on the extracted colors, we designed four app icons for each of the categories with different color combinations based on a high/low level of matching with users’ emotional image and an analogous/complementary use of colors in app icons. We collected data for empirical testing through a laboratory experiment. The results reveal that a high level of matching with users’ emotional image and an analogous use of colors in app icons positively influence users’ preference for an app, and intention to download their intention to download the app.

Audit Firm Attributes and Auditor Litigation Risk, ABACUS (A Journal of Accounting, Finance and Business Studies), Á¦55±Ç, Á¦4È£, 2019.12   

This study examines the association between auditors' litigation risk and audit firm attributes. Using professional liability insurance premiums as a proxy for auditors' litigation risk, we present evidence that the risk is lower in audit firms having: (1) separate non‐audit and audit divisions; (2) a higher proportion of partners; and (3) a higher annual growth in number of CPAs employed. Additionally, we find that the risk is higher in audit firms having: (1) operating losses; and (2) high revenue growth. Our results are consistent with the idea that audit firms' financial condition and organizational structure affect their independence. expertise, and, in turn, their litigation risk. Our results are broadly supportive of the PCAOB's (2015) and US Department of Treasury's (2008) views that investors, audit committees, management, and other regulators could benefit from having access to financial and organizational information about audit firms.

The University Examination And Course Timetabling Problem With Integer Programming, Journal of The Korea Society of Computer and Information, Á¦24±Ç, Á¦9È£, 2019.09

In this paper, we study the university timetabling problem, which consists of two subproblems, the university course timetabling problem and the examination timetabling problem. Given a set of classrooms, students, teachers, and lectures, the problem is to assign a number of courses (and examinations) to suitable timeslots and classrooms while satisfying the given set of constraints. We discuss the modeling and solution approaches to construct course and examination timetables for one of the largest Korean university. By using binary integer programming formulations, we describe these two complex real-world problems. Then, we propose a solution method, called NOGOOD, to solve the examination timetabling model. The computation results show that NOGOOD finds the optimal examination schedule for the given instance. Although we consider a specific instance of the university timetabling problem, the methods we use can be applicable to modeling and solving other timetabling problems.

This study explores the partial inverse traveling salesman problem (TSP). In partial inverse problems, the task is to modify the associated weight system as minimally as possible so that the given partial solution can become a part of an optimal one in a new instance. In partial inverse TSPs, the task is to determine a new edge weight system in which the given partial solution of TSP (the given sequence of consecutive edges) can be included in the minimum Hamiltonian cycle of a new instance. The objective can be measured by the difference between the original and new weight systems under a fixed norm. In this work, we introduce several variants of the partial inverse TSP and investigate their complexity status.

The Effect of a Companion’s Role-Play Quality on the Patient’s Perceived Healthcare Service Quality, ¼­ºñ½º°æ¿µÇÐȸÁö, Á¦21±Ç, Á¦1È£, 2020.03

The importance of a companion as a value cocreator has been conceptually proposed but is yet to be empirically examined. Studies on companions and their roles have focused mostly on particular aspects and are primarily descriptive in nature. A comprehensive account of the companionship role is yet to be accomplished. With healthcare services as the study context, this study first identifies the companionship role and carries out an empirical examination. Using field survey data from 201 respondents, a three-factor scale for companionship roles with two items for informational role, four items for emotional role, and four items for communicative role is first validated. And then, a structural equation modeling analysis tests proposed hypotheses. Results show that a patient’s perceived quality of his/her companion’s role-play during the service delivery process positively affects the customer’s perceived quality of the healthcare service rendered by the healthcare firm. The moderation effect of customer-companion relationship quality is also demonstrated.

Asymmetric Learning from Prices and Post‐Earnings‐Announcement Drift, Contemporary Accounting Research, Á¦36±Ç, Á¦3È£, 2019.09

Motivated by research in psychology and experimental economics, we assume that investors update their beliefs about an asset's value upon observing the price, but only when the price clearly reveals that others obtained private information that differs from their own private information. Specifically, we assume that investors learn from the price of an asset in an asymmetric manner—they learn from the price if they observe good (bad) private information and the price is worse (better) than what is justified based on public information alone. We show that asymmetric learning from an asset's price leads to post‐earnings‐announcement drift (PEAD), and that it generates arbitrage opportunities that are less attractive than alternative explanations of PEAD. In addition, our model predicts that PEAD will be concentrated in earnings surprises that are not dominated by accruals, and it also predicts that earnings response coefficients will decline in the magnitude of the earnings surprises.
