研究室紹介
Professor Jai Yeol Son's research lab specializes in information systems and e-commerce, with a focus on digital marketplaces, electronic trading systems, and consumer behavior in online environments. The lab investigates key factors influencing organizational adoption and sustained usage of B2B electronic marketplaces, interorganizational systems (IOS), and over-the-top (OTT) streaming services, emphasizing trust, relational dynamics, and user experience. Research also explores the role of infomediaries, recommendation agents, and post-adoption behavioral outcomes such as continuance intention and word-of-mouth. The lab integrates institutional theory, transaction cost theory, and technology acceptance models to examine how systemic and relational factors shape digital platform success.

15Despite the significant opportunities to transform the way that organizations conduct trading activities, few studies have investigated the impetus for organizational strategic moves toward business-to-business (B2B) electronic marketplaces. Drawing on transaction cost theory and institutional theory, this paper identifies two groups of factors—efficiency- and legitimacy-oriented factors, respectively—that can influence organizational buyers' initial adoption of, and the level of participation i
Sustained website traffic through consumers' patronage at the post-adoption stages is known as a key to the survival of an online service provider. Although a firm's survival depends much on repeated use, whether or not a firm survives is also influenced by a variety of other behavioral outcomes that include, but are not limited to, word-of-mouth, willingness to pay, and inattentiveness to alternatives. Whereas post-adoption research has recently paid attention to repeated use, the information s
Managing electronic trading partner relationships is a key to successful development of an interorganizational systems (IOS) network. Firms often exercise their power and offer reciprocal investments to their trading partners in developing an IOS network. However, limited effort has been made to empirically validate their effects on increasing IOS usage between trading partners. This paper gauges the effects of these two relational factors--power and reciprocal investments--within the context of
Purpose Over-the-top (OTT) services, which provide streaming media through all devices in online setting, have surpassed the traditional content providers in the market. However, there is still no clear empirical evidence that indicates what recommendation agent values affect the users' search experience while using the OTT services and how it leads to continuous subscription. To address this gap, this study aims to examine recommendation agent values influencing search experience, which in turn
Because business-to-business (B2B) electronic marketplaces (e-marketplaces) facilitate transactions between buyers and sellers, they strive to foster a trustworthy trading environment with a variety of trust-building measures. However, little research has been undertaken to explore trust-building measures used in B2B e-marketplaces, or to determine to what extent these measures are applied in B2B e-marketplaces and how they are applied. Based on reviews of the scholarly, trade, and professional
The emergence of infomediaries ?which allow online consumers to search for, and provide comparisons among, many online retailers ?is a prominent trend in e-commerce. However, little research has been done on consumer reactions to this new e-commerce tool. To explain why and how online shoppers adopt a new infomediary website, this study proposes a conceptual model with insights obtained from literatures on the technology acceptance model (TAM), the economics of intermediation, and transaction co
Two prominent trends—more cooperative business partner relationships coupled with rapid advances in computer and communications technology—have given rise to new forms of electronic cooperation through interorganizational systems (IOS). In spite of this emerging electronic cooperation, existing literature is limited in its ability to pinpoint the core set of factors that determine the extent of the electronic cooperation between trading partners. By investigating the use of electronic data inter
Purpose Firms continue to struggle with end users who do not follow recommended actions for safeguarding information security. Thus, the authors utilize insights gained from studies on heuristic processing of risk information to design cues in fear appeal messages more effectively so as to more strongly engender fear among users, which can in turn lead them to take protective actions toward information security. Specifically, four types of fear appeal cues are identified: numeric risk communicat
Abstract The success of on-line marketplaces hinges on their ability to attract and retain sellers as well as buyers. The extant literature focuses on understanding the behavior of buyers, however, and few studies have tackled issues central to the performance of sellers. As a first step to fill this gap, this study systematically examines the effect of market knowledge from intermediaries on the performance of sellers in on-line marketplaces. Specifically, using a knowledge-based view of the fi
본 연구는 유튜브 이용자들이 정보탐색 중 발견하게 되는 유튜브의 IT 기능들이 휴리스틱 단서로써 컨텐츠에 대한 태도 및 시청 의도에 미치는 영향에 대하여 살펴보고자 하였다. 휴리스틱-체계적 모델(Heuristic-Systematic Model: HSM)에 따르면 사람들은 유용한 정보를 빠르게 선택하여 처리해야 하므로 눈에 띄는 단서인 휴리스틱 단서에 의존하는 경향을 보인다. 본 연구에서는 유튜브 내 존재하는 IT 기능들을 기반으로 발현되는 휴리스틱 단서에 집중하였다. 문헌 연구 및 인터뷰를 기반으로, 콘텐츠에 대한 태도에 영향을 미치는 여러 가지 요소 중에서도 유튜브 내 IT 기능을 통해 발현될 수 있는 세 가지 요인인 사회적 지지, 유튜버의 자기표현, 상호작용성을 도출하여, 해당 요인들을 바탕으로 실험을 진행하였다. 유튜브 속 IT 기능들이 활발히 사용되어 사회적 지지, 유튜버의 자기표현, 상호작용성이 높게 인지되는 경우, 해당 콘텐츠에 대한 태도가 호의적으로 형성되어 시청 의도에
Two well-grounded motivational models-command-and-control and self-regulation, which are viewed as competing explanations of why individuals follow rules (Tyler and Blader 2005)-are used as conceptual lenses through which to view employees' adherence to information systems security policy (ISSP).Specifically, we aim to identify specific factors drawn from each of the two competing approaches that determine the level of employees' adherence to their organization's ISSP, and to develop and empiric
