Credit ratings and corporate disclosure behaviour: evidence from regulation fair disclosure in Korea

This article provides evidence that firms with high market expectations disclose more information to investors, utilizing the fair disclosure regulation in Korea to proxy for their disclosure choices. This finding is consistent with the argument that in order to retain their dominant positions, highly evaluated firms are more concerned about the market’s perception of them as providers of timely and detailed disclosure. We also find that the impact of market expectations on disclosure is more pronounced for chaebol firms. Combined with prior research on the relationship between firm performance and voluntary disclosure, we provide important implications for the determinants of corporate disclosure     

The appealing characteristics of download type mobile games

As the mobile game industry enjoys continual and rapid growth in the market and becomes a major sector of the service industry, it is of great interest to examine the very features that make mobile games so fascinating and keep its players coming for more. Pinpointing more precisely the very factors that increase the attraction of games will help game makers allocate corporate resources more efficiently. In addition, a more in depth analysis of the appealing characteristics enable game producers to establish an organized strategy in developing more advanced and technologically sophisticated mobile games, and to enhance their competitive advantage. In order to find these factors, we proposed a model, analyzed empirical data, and then interpreted the results. In this study, we examined the download type mobile game to find and compare factors that cause intent to play. The suggested model has three layers. The top layer is the intent to play mobile games. The second layer, the psychological perception layer, consists of two perceptive factors: perceived enjoyment, and perceived copresence. The third layer is a technological layer, used to classify the characteristics of the mobile games content into image, communication, and attractive characteristics, all of which have relationships with perceptive factors. The study shows some interesting results and we believe the conclusion and implications of this research will be useful for mobile game scholars and industry participants.     

Analysis of product efficiency in the Korean automobile market from a consumer’s perspective

In this study we develop and describe a conceptual and methodological framework to measure technical and allocative efficiency at the product level considering consumer choice, which encompasses overall efficiency. Empirically, we combined data envelopment analysis and a discrete choice model in order to measure efficiency levels. The suggested framework is applied to the Korean automobile market. The relationship between the level of efficiency and market performance is discussed in terms of market share.     

Social Media for Socially Responsible Firms: Analysis of Fortune 500’s Twitter Profiles and their CSR/CSIR Ratings

The instrumental benefits of firm’s CSR activities are contingent upon the stakeholders’ awareness and favorable attribution. While social media creates an important momentum for firms to cultivate favorable awareness by establishing a powerful framework of stakeholder relationships, the opportunities are not distributed evenly for all firms. In this paper, we investigate the impact of CSR credentials on the effectiveness of social media as a stakeholder-relationship management platform. The analysis of Fortune 500 companies in the Twitter sphere reveals that a higher CSR rating is a strong indicator of an earlier adoption, a faster establishment of online presence (followers), a higher responsiveness to the firm’s identity (replies and mentions), and a stronger virality of the messages (retweets). Incidentally, the higher CSIR rating is also found to be associated with the stronger virality. Our findings also suggest that socially responsible firms can harvest proactive stakeholders’ participation (user-driven communication) without investing more resources (firm-driven communication). As the first study that conceptualizes the social media as a proponent of CSR, this paper contends that “being socially responsible” makes more practical sense for firms with the rise of social media.     

Adoption of digital repositories for CO2 emissions reduction: the case of Korea

This study aims to estimate the potential economic benefits, energy and CO₂ emissions reductions when using trusted third-party digital repository (TTPR) services in one individual bank, and within the banking industry in Korea. First, the cost, benefit and net benefit of using TTPR services in the banking industry are estimated. Second, the net induced output effect is estimated. Third, based on an environmentally extended input–output analysis, CO₂ emissions reduction was estimated as 1924.32 tons in 2009 and the energy consumption reduction as 640.70 TOE. Fourth, the total economic benefit, which is the sum of the net induced output effect and economic value of CO₂ emissions reductions, is approximately $11.04 million. The findings demonstrate that energy consumption and CO₂ emissions reductions are meaningful enough to result in significant economic benefits. Therefore, the Korean government should promote the use of TTPR services in the entire industry.     

Hospitality and tourism marketing: recent developments in research and future directions

This study reviews marketing research published in selected hospitality and tourism journals for the period of 2002–2003. The review includes summaries of research topics, industry applications, and methods of study design and data analyses. Significant topical research trends are identified and discussed to raise issues for future research. Included also are the industry-specific current trends and issues that dictate immediate research attention. The gaps between hospitality and tourism marketing research and industry's research needs are addressed to encourage additional research on neglected topics. The study concludes with general suggestions for future hospitality and tourism marketing research.     

Korean Television Dramas and the Political Economy of City Promotion

This article examines the ways in which urban processes are associated with the production of culture. It does so by exploring how Korean cities sponsor drama. The historically conditioned and economically neglected status of regional cities, combined with elected local leaders' desire to promote their own areas, has led to a strategy to publicize them by leveraging the popularity of Korean television dramas in Asia. Two distinct types of drama sponsorship by cities — the construction of outdoor settings for drama and ‘city placement’ — manifest the interactions between story‐making and place‐making. The affective process that blends city sites with the characters, storylines and emotional flows of TV drama imbues those sites with a dramatic quality that stimulates the audience's empathy and persuasively motivates them to actually visit the places they have seen televised. Thanks to the broad penetration of television drama, sponsorship by cities has strikingly boosted drama‐driven tourism. Nevertheless, reflecting the speculative nature of TV drama, city promotion through this medium has had limited stability and sustainability. In sum, this article demonstrates that the production of Korean television dramas is deeply associated with the material and spatial conditions in Korean cities.     

The time difference effect of a measurement unit in the lead-lag relationship analysis of Korean financial market

This paper investigates Korean financial markets for the study of market microstructure of price discovery in the KOSPI 200 stock index and its related derivatives markets using different time-interval price data. The Granger causality test and vector error correction model are used to analyze the empirical relationship between markets. The lead-lag relationship between the KOSPI 200 stock index and its derivatives markets can be supported by the trading cost hypothesis and leverage effect hypothesis. This paper also shows the congruent lead-lag results in various time-intervals, but as the time-interval becomes large, more information loss and spurious results are induced. The correlations among 1-minute data, 5-minute data, and 10-minute data are significant under a 1% significance level, however, in the case of 60-minute data, the correlations with any other time-interval data are not significant. The 60-minute data even have negative correlations with others. These results are consistent regardless of the raw data or the innovation data. Therefore, we can conclude that the previous research using the 60-minute data due to an insufficiency of trading volume can be biased considerably.
