Product Market Competition and the Ownership Choice of Business Groups: Evidence from Korean Chaebols

This study investigates the effect of product market competition on the ownership choice of controlling shareholders in the Korean business groups known as chaebols. We find that member firms in more competitive markets have less disparity between the control and cash flow rights of controlling shareholders. The adjustment in ownership due to product market competition is implemented mainly through an adjustment in the ownership of affiliates rather than in the direct ownership of controlling shareholders. The disciplinary effect of product market competition is observed only in member firms with lower market power in their own industries. The result implies that product market competition works as a disciplinary mechanism that reduces the incentive of chaebols’ controlling shareholders to pursue the private benefits of control.     

Re-evaluation of global innovation index based on a structural equation model

The Global Innovation Index (GII) was proposed to observe the innovation capability and efficiency levels of individual countries using input and output factors. However, it does not consider potential structural relationships among factors affecting the innovation performance of a country. In this study, we proposed a structural equation model (SEM) based on the hypothesised national innovation structure among seven factors representing inputs (institution, human capital and research, infrastructure, market sophistication, and business sophistication) and outputs (knowledge and technology outputs, and creative outputs). Using GII data from 2013, we discovered that business sophistication and infrastructure have the strongest direct and indirect effects on creative output, respectively. In addition, a new ranking is obtained based on the fitted SEM. We provide feedback information to improve innovation capabilities.     

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.     

Does Strategic Planning Enhance or Impede Innovation and Firm Performance?*

Does strategic planning enhance or impede innovation and firm performance? The current literature provides contradictory views. This study extends the resource‐advantage theory to examine the conditions in which strategic planning increases or decreases the number of new product development projects and firm performance. The authors test the theoretical model by collecting data from 227 firms. The empirical evidence suggests that more strategic planning and more new product development (NPD) projects lead to better firm performance. Firms with organizational redundancy benefit more from strategic planning than firms with less organizational redundancy. Increasing R&D intensity boosts both the number of NPD projects and firm performance. Strategic planning is more effective in larger firms with higher R&D intensity for increasing the number of NPD projects. The results reported in this study also consist of several findings that challenge the traditional views of strategic planning. The evidence suggests that strategic planning impedes, not enhances, the number of NPD projects. Larger firms benefit less, not more, from strategic planning for improving firm performance. Larger firms do not necessarily create more NPD projects. Increasing organizational redundancy has no effect on the number of NPD projects. These empirical results provide important strategic implications. First, managers should be aware that, in general, formal strategic planning decreases the number of NPD projects for innovation management. Improvised rather than planned activities are more conducive to creating NPD project ideas. Moreover, innovations tend to emerge from improvisational processes, during which the impromptu execution of NPD activities without planning spurs “thinking outside the box,” which enhances the process of creating NPD project ideas. Therefore, more flexible strategic plans that accommodate potential improvisation may be needed in NPD management since innovation‐related activities cannot be planned precisely due to the unexpected jolts and contingencies of the NPD process. Second, large firms with high levels of R&D intensity can overcome the negative effect of strategic planning on the number of NPD projects. Specifically, a firm's abundant resources, when allocated and deployed for NPD activities, signal the high priority and importance of the NPD activities and thus motivate employees to acquire, collect, and gather customer and technical knowledge, which leads to creating more NPD projects. Finally, managers must understand that managing strategic planning and generating NPD project ideas are beneficial to the ultimate outcome of firm performance despite the adverse relationship between strategic planning and the number of NPD projects.     

The Influence of Partner Knowledge Complementarities on the Effectiveness of IT Outsourcing

Despite the importance of knowledge complementarities to inter-firm cooperation, few researchers in information systems (IS) have examined, to date, the construct of knowledge complementarities (KC), and none have examined its role in the success of IT outsourcing alliances. In this paper, we distinguish between potential knowledge complementarities (PKC) and synergistic value, which comprise KC. PKC is conceptualized as a multidimensional construct encompassing knowledge types (similar and specialized) and knowledge domains (business and IT). Further, we examine the extent to which PKC between the client and the vendor promotes success in IT outsourcing alliances. This research also includes relative absorptive capacity because it is relevant when complementary knowledge flows between organizations. We used data from a field study of 81 firms in Korea to test the proposed model. Our findings indicate that each dimension of PKC contributes uniquely to knowledge complementarities. The results also show that PKC is significantly associated with IT outsourcing effectiveness. Relative absorptive capacity is found to be a moderator between PKC and IT outsourcing effectiveness. The theoretical and practical implications of these findings are discussed in the paper.     

Inter-organizational cooperation in buyer-supplier relationships: Both perspectives

Most empirical investigations of inter-organizational cooperation within channel dyads investigate the phenomenon from the perspective of only one partner. However, because investigating from both partners' perspectives is important especially when interdependencies exist between the channel partners, this study attempts to examine both perspectives in buyer-supplier relationships and explain why differences, if any, arise. The data that this study requires were collected from buyers responsible for supplier relationships in a Korean telecommunication service provider and from their partners. The results show that switching costs and inter-organizational trust are significant determinants of cooperation for buyers; technological uncertainty and the reciprocity of the relationship are significant determinants for the suppliers. In both sample sets, goal consistency significantly affects inter-firm cooperation.

The mechanism by which social media influencers persuade consumers: The role of consumers’ desire to mimic

We explore the mechanism through which social media influencers (SMIs) persuade consumers to adopt brands. Guided by the influence framework, we propose and test empirically SMIs’ influence mechanism, which occurs in four principal stages: (a) a SMI's influence attempts (showcasing H1: attractive; H2: prestigious; H3 and H4: expert; H5: informative; and H6: interactive Instagram contents); (b) target consumers’ attitudinal response to the influence exercised (evaluating the SMI as a H7: taste and H8: opinion leader); which, in turn, affects (c) the targets’ desire to comply (the desire to mimic); and ultimately (d) their favorable behavioral outcomes (H9: social media word‐of‐mouth and H10: purchase intentions). On the basis of the survey data from 395 respondents, we used structural equation modeling to test our hypotheses and proposed model. We verified the robustness of our results using an ordered probit regression model and analyzed the mediating role of consumers’ desire to mimic SMIs in the influence mechanism. Our results confirm that the five aspects of influencing posts affect consumers’ attitudes positively and significantly, which in turn leads to positive behavioral outcomes through their desire to mimic SMIs. We discuss the results’ important implications for both scholars and practitioners.
