This study aims to test the valur relevance of development cost particularly focusing on IT firms of KOSDAQ. Test period is from 2005 to 2007 and the samples are 2,271 year-firms including 1,692 firms that reported development cost in financial statements. The basic test model is a modified Ohlson(1995)'s linear model. The empirical results show that there is the negative relation between stock price and development cost reported as asset. It means that development costs reported as asset is considered as expense in the market. It implies that development activities of KOSDAQ IT firms is not related to market-leading technologies or goods. Otherwise it might reflect the conservative valuation of market on the unstability of KOSDAQ market itself.

The purpose of this paper is to examine a financial distress premium in the emerging market. A risk-return trade-off of negative book equity (NBE) and distress firms is empirically analyzed using data from the Stock Exchange of Thailand. This research employs Ohlson's (1980) bankruptcy model as a measurement of distress risk. The results indicate that distress firms outperform solvent firms in the Thai market and deny distress anomaly often found in the developed market. Fama-Frech (1993) three-factor model and Carhart (1997) four-factor model verify the existence of a distress premium in the Thai capital market. Risk-seeking investors demand greater compensation for bearing risks of distress firms' going concern. This paper provides fresh evidence that default risk is a significant explanatory factor in pricing stocks in the emerging market. Also, this study sheds light on the role of NBE firms in asset pricing. Most studies eliminate NBE firms from their sample. However, NBE firms yield superior average cross-sectional returns, albeit with higher volatility. Investors are rewarded with distress risks associated with NBE firms. The outperformance of NBE firms is statistically significant when compared to the overall market. The NBE premium disappears when factoring size, value, and momentum in time-series analysis.

Purpose - This paper empirically investigates the relationship between the corporate value chain and performance of non- financial businesses of South Korean stock market companies. It aims to explore the evidence that can be used to infer the relationship between value chains and corporate performance in the case of firms forming a value chain with other companies with the means of an equity investment or a special business relationship. Design/methodology - Non-financial corporations listed from 2011 to 2017 on the securities market of South Korea are analyzed. The data used for analysis are found for transactions with the related party by year for all the corporations of non-financial industries in the securities market. Multiple analysis attempts are conducted including the relationship between the value chain and productivity, corporate value, risk-adjusted corporate value, and mediation effects of productivity. The empirical model employs sixteen variables including the value chain index which identifies its impact on various aspects of business performances. Findings - The results of this study clearly supports the phenomenon that corporate productivity and value are enhanced when the corporation expands its value chain established with domestic related firms and overseas companies. Such a positive effect is statistically significant even after the possible risk factors that accompany the expansion of value chain were considered, and productivity plays the role as a medicating variable in the effect of the value chain on the corporation values. Originality/value - The findings of this study confirms that domestic companies' expansion of their value chain centered on the related firms overseas that helped them in terms of the maximization of their productivity and corporate values. This study shows that Korean government's policy on expanding the corporate GVC can enhance the productivity and value of firms. The expansion of value chain and its impact on business performance has not been explored thoroughly, although it is getting more and more important in the global trade operation.

Large business groups typically have central firms through which their controlling families establish (or acquire) new firms and maintain control over other member firms. Research on corporate governance has developed metrics to identify those central firms and investigated an impact of the centrality on ownership structure and firm's financial performance. This paper introduces centrality metrics used in social network analysis (SNA) to measure how crucial a role each firm plays in the ownership structure of its business group. Then, the SNA centrality metrics are compared with the metrics developed in corporate governance field. Also, we test the relationship between the SNA centrality metrics and firm's value. Experimental results show that the SNA centrality metrics are closely correlated with the centrality metrics used in corporate governance and are significantly correlated with firm's value.

Purpose - A business ecosystem refers to mutually dependent systems interconnected by a loose foundation of various ecosystem members such as customers, suppliers, partners, and other stakeholders. The ecosystem-based strategy attempts to achieve competitive advantage for firms by enriching a business ecosystem or building a sustainable business ecosystem through the collaboration and co-evolution of its members. A sustainable business ecosystem is a source of competitiveness for firms anda manageable resource for gaining a competitive advantage. Customers represent the core membership of the business ecosystem and play a pivotal role in building a sustainable business ecosystem. This study examines the effects of customer participation on economic and social value in the business ecosystem and suggests a course of action for building a sustainable business ecosystem. Research design, data, and methodology - Two business cases of South Korea are selected from two different business types: business-to-business (B2B) and business-to-customer (B2C) firms. Business ecosystems for B2B and B2C firms reflect contrasting characteristics. Data was collected from in-depth interviews with four representatives of four firms. Results - The study suggested seven propositions for the relationships between customer participation and a sustainable business ecosystem through multiple case studies based on in-depth interviews. The results reveal the following four strategic actions for building sustainable business ecosystems based on the suggested propositions: alignment, systemization, socialization, and co-evolution. Alignment refers to achieving a harmonic balance or virtuous circle among the firm's mission, investment, and value creation. Systemization refers to building and implementing management and infrastructure systems rooted in the corporate culture. Socialization of customers in the business ecosystem reinforces the harmony or virtuous cycle. Finally, co-evolution is associated with the relationship between firms and customers as buyer firms in a restricted business ecosystem. Conclusions - This study considers multiple cases for the execution of a sustainable business ecosystem in collaboration with customers and suggests seven propositions and four strategic actions. The results are based on qualitative data from interviews with business associates from two firms in an open business ecosystem and two firms in a restricted business ecosystem, both in South Korea. Our research results regarding two contrasting business ecosystems shed light on business issues and policy making in Asian business environments, which are in the transition stages from a traditional conglomerate-driven to an inclusive growth-driven economy. The business ecosystem itself should be considered a manageable resource for firms' competitive positions in the market. A customer is a member of the business ecosystem and should thus be viewed not only as a purchasing entity and an object of relationship management but also as a co-creator of value. Therefore, firms should collaborate with customers to build sustainable business ecosystems. For this, firms must create social value, which cannot be created by customers alone, within the business ecosystem. Then, customers participate in a business ecosystem and build it to be favorable to them. Implications for academics and practitioners were suggested.

Win-win growth between large companies and small and medium enterprises (SMEs) become a critical encomic and social issue in Korea. Korea government has been attempted to establish strong policy to build right win-win relationship between large companies and SMEs. Along with this strong drive from Korea government, a variety of strategies that enhance win-win relationships between large companies and SMEs have been adopted. Win-win growth policy is expected to provide positive impact on sustainable competitive advantage of firms. Therefore, many studies have focused on the win-win growth policy success factors, type of the policy, and the results of the policy. Although there is much literature on the win-win growth policy, the effects of win-win policy on firm value is not well understood. We addressed this issue by exploring how win-win growth policy influences a firm's market value using event study methodology. We evaluated the cumulative abnormal returns for win-win growth policy announced by Korean large firms from 2004 to 2012. The results of this study insisted that the announcements of win-win growth policy show negative impact on firm's market value, which is not consistent with previous studies. The findings of this study offer insights that may help government policy makers and managers to revise their policy for better outcomes of their win-win growth policy.

The purpose of this paper is to examine the effect of tax planning on firm value of the non-financial firms listed in Vietnam, moderated by the state ownership. In this paper, effective tax rate is used to measure the tax planning; the state ownership is measured by the percentage of state equity holdings, and the firm value is measured by Tobin's Q. The data research is collected from audited financial statements and other statistical documents of 513 firms in the period of 2015-2019, provided by The FiinGroup (Vietnam). According to that, this paper uses quantitative research methods for the panel data. Regression analysis with GLS shows that the tax planning has a negative effect on firm value. In more detail, the association is not a variable in its direction when state ownership takes the role of a moderator. That means, in the perspective of principal-principal conflict, government should improve institutional environment to prevent firms form breaking the rules, especially accounting standards and principles. Assets allocation in tangible assets or making use of large size advantage should be taken into account. In the long run, firms should concentrate on the deployment of resources and the experience of knowledgeable practitioners to produce effective results.

Purpose - As recently social contributions of firms are positioned as key strategic actions, it is demanding to review the effects of social contributions on overall corporate management. The research aims to effects of social contributions on social values and word of mouth in firm level and product level. Further roles of consumer identification with firm and product eco-friendliness are also analyzed. Research design, data, and methodology - The paper conducted a survey in which two scenarios are used for manipulating the degree of corporate social contributions. The survey sample consist of 165 undergraduate and graduate students in a university, located in Seoul. For analyzing data, analysis of variance is applied, in conjunction with analysis of moderating effects, through version 23 of SPSS statistical package. Results - In the firm level, social contributions by firms have a positive effect on social values of firms. Consumer identification showed a moderating role in the effect. Social value of the firm with passive social contribution perceived by respondents with a high degree of identification was higher than social value of the firm with active social contribution perceived by respondents with a low degree of identification. Corporate social value has positive effect on word-of-mouth of firms. In the product level, social contributions by firms has a positive effect on social values of product. Product eco-friendliness showed a moderating role in the effect. For eco-friendly product, social values are higher in the firm with active social contributions than in the firm with passive social contributions. However, for non eco-friendly product, the difference in social values between the two firms does not exist. Product social values has positive effect on intention for WOM of products. WOM of eco-friendly products with low social value showed no difference with WOM of non eco-friendly products with high social value. Conclusions - These results imply that firms should enhance consumer identification with firm in making social contributions for optimizing corporate social value and enhancing word-of-mouth(WOM). Managerial implications of the results suggest it would be more effective to improve social value of product by active social contributions for increasing word-of-mouth(WOM) of product.
