As recommendation algorithms have been increasingly applied to content personalization services, scholars are voicing concern about the negative impacts of these algorithms, for instance filter bubbles and ideological polarization. This research attempts to analyze the various factors influencing users' continuance intention of recommendation algorithms through structural equation modeling. Based on the Expectation-Confirmation Model, this study proposes an extended framework to empirically examine the impact of confirmation, perceived usefulness, perceived enjoyment, perceived ease of use, perceived risk, and subjective norm on satisfaction and continuance intention. Results indicate that confirmation positively impacts satisfaction, perceived usefulness, and perceived enjoyment. Furthermore, all constructs had a significant effect on satisfaction as well as continuance intention. A group comparison analysis of consumers primarily using news recommendation algorithms and multimedia recommendation algorithms uncovered differences between the two groups. Managerial implications on how to retain recommendation algorithm users are suggested based on the results.

The long-standing signification of car is expected to accompany a big change, which results in the concept of smart car that can not only improve traffic safety by driving and controlling themselves like robots, but also entertain passengers and support their productive activities through connection to the Internet. Many related companies are seeking to enter the smart car market to take a leadership in the growing smart car market. While there are some researches regarding advanced technologies regarding smart car, there are relatively few efforts that focus on the standpoint of market demand. This study thus aims to understand customer value on upcoming smart car through evaluating the relative importance of idiosyncratic key services of smart car based on analytic hierarchy process analysis. In addition, this paper also evaluates firms and industries that are expected to perform well the preferred services through expert survey. The results show that the most important service is driving assistance, followed by infotainment, and IoT hub. Furthermore, Samsung Electronics ranked the highest, followed by Hyundai Motor, Naver, and SKT. In terms of industries, the rank is in the order of IT equipment manufacturers, platform providers, automobile manufacturers, and network providers. This analysis could help companies diagnose their capabilities and recognize their strengths and weaknesses.

Recently, the consumer virtual reality(VR) industry has been established with the introduction of VR head-mount displays(HMDs) and many have expected VR to become the next generation platform. Despite the circumstances, the adoption of VR HMDs is slower than expected. To comprehend this matter, this study explored consumers' preference on the attributes of VR HMDs by implementing the conjoint analysis methodology and deriving the marginal willingness-to-pay(MWTP) of the attributes. Based on past literature and analysis of the product, six attributes were derived: Visualization, Accessories, Weight, Ergonomic Design, Number of Contents, and Price. The results indicate that the wearable aspect of the device is the most important. Implications for future developmental directions for VR HMDs are suggested based on the results.

Smart speakers have become next big thing in IoT industry. However, there is not enough discussion about which application would be killer content in smart speaker market. To boost market participation and the growth of the market, there should be a research predicting killer service in the smart speaker. This study uses an AHP model and framework to assess the priority for applications in smart speakers. This study compares three types of applications – Music, News, E-commerce – to investigate the priority.

Personal information is essential in an information-oriented society for societal development and as a valuable business resource. However, because of poor management and a lack of proper protection, leakage of personal information can take place over time, and the standard for compensation is not well established. In order to establish appropriate policies for its protection, we need to know the economic value of personal information. Using conjoint analysis, we analyze the potential value of personal information by calculating the marginal willingness to pay of Korean consumers for each attribute of personal information, which we estimate to be 7501.70 South Korean won (about 6.81 US dollars) per month. After indirectly estimating the economic value of personal information, we provide some political implications regarding the potential market size of any personal information protection service.

This study identifies and analyzes the causes for WiBro's failure in the Korean telecommunications market within the context of the technological systems framework and the actor-network theory. The reverse salients of WiBro were identified according to the activities of the actors from three different domains: technology, government, and business. The findings and implication of this study were obtained through a review of the literature and in-depth interviews with eight key experts. The reverse salients found can be categorized into two types: 'apparent' and 'underlying.' The apparent reverse salients are the lack of investment and inadequate business model of the business actors. The underlying reverse salients are the policies enacted by government actors and are less obvious but heavily influence the creation of the apparent reverse salients and ultimately contribute to the failure of WiBro.

With the increasing use of smart devices recently, mobile traffic has been increasing rapidly, which in turn results in greater demand for the frequency. Many countries have attempted to use the vacant frequencies known as TV White Space (TVWS) in an effort to solve the frequency problem. Super Wi-Fi service, a wireless Internet service based on TVWS, is one of the ways TVWS is being utilized. This paper applies conjoint analysis to evaluate consumers’ willingness to pay for each of the attributes of Super Wi-Fi service and estimates how much consumer welfare could be improve by the introduction of Super Wi-Fi service. The attributes of Super Wi-Fi service are coverage, a reduction in communication expenses when using mobile data, the ability to use multiple-screens, and a wide range of Wi-Fi service providers. The results based on user surveys indicated that the marginal willingness to pay (MWTP) amount per month for Super Wi-Fi service is KRW 4,717 (USD 4.6). Moreover, the MWTP amount in non-urban areas for this service is greater than that in urban areas, implying that the introduction of Super Wi-Fi service is expected to increase consumer welfare, especially in non-urban areas.

Car is now more than just a transportation method. Now a smartphone or a portable device can be easily connected to your car and this allows us to enjoy broader range of contents like music and navigation. This study aims to study investigate what leads drivers to use such car-connectivity services. Based on the Unified Theory of Acceptance and Use of Technology (UTAUT) as theoretical framework, this study examines the relationship between four derived constructs (facilitating condition, technographics, mobile literacy, and prior similar experience) and behavioral intention to use car connectivity functionalities. The results show that two of them (facilitating condition and technographics) have significant impact on the intention to use car connectivity services but the other two (mobile literacy and prior similar experience) did not show statistically significant relationship with the behavioral intention.

In recent years, patent lawsuits in the IT industry have become a sensitive issue. While numerous studies have investigated the wealth effect of patent and corporate litigation, few studies have examined the current patent litigation in the IT industry. This paper investigates the wealth effect of patent lawsuits using an event study method. This paper hypothesizes that a firm which initiates a lawsuit experiences more of a positive return than a rival firm when the patent lawsuit filing is announced, as a firm will initiate a lawsuit when they are convinced that they have a vantage position in the patent lawsuit. The empirical results show that a firm which has a vantage position in a patent lawsuit experiences a positive stock price return when they sue a rival firm for patent infringement and that a firm which does not have a vantage position in a patent lawsuit experiences a negative stock price return when they are sued by a rival firm. The empirical results support that a vantage position in patent litigation is the one of the key factors to explain the wealth effect of patent litigation. This paper suggests that action to increase patent competency to reach a vantage position in a patent war is one of the ways to increase shareholder value.

This study examines whether competition improves corporate performance in Korean economy. Market competition promotes managerial efforts for cost reduction and innovation, while market concentration enables managers to enjoy a "quiet life". The effect of competition can be substituted, to some extent, by that of financial distress. Financial constraint also puts managers in more efforts for higher efficiency of firm. Our analysis of the 2001-2009 panel data of 1,800 Korean firms supports the hypothesis of positive relationship between competition and performance. The negative effect of financial distress is also more evident in highly concentrated markets such as IT industry.
