研究室紹介
Professor Changi Nam's research lab specializes in corporate finance, telecommunications industry dynamics, and sustainability in business, with a strong focus on mergers and acquisitions, earnings management, and the financial implications of strategic corporate actions. The lab investigates how market participants react to corporate events such as M&As, particularly in the context of telecommunications and mobile platform ecosystems, and explores the role of sustainability and value chain reconfiguration in driving long-term financial performance. The research integrates theoretical frameworks like the theory of reasoned action and Ohlson's residual income model with empirical analysis using unique datasets such as the Korea Sustainability Index and U.S. telecommunications M&A data. The lab also examines the interplay between regulatory events—like government licensing—and market perceptions of corporate deals.

15Abstract Corporate sustainability has increased in importance, because corporations must survive in a social and ecological network as an interdependent going concern. However, from a business perspective, it is an empirical issue whether the firm's corporate sustainability performance is associated with its financial performance. In this paper, based on Ohlson's residual income model, the effect of corporate sustainability performance on financial performance is examined by utilizing the newly
This paper investigates how market participants react to mergers and acquisitions (M&As) involving telecommunications companies. The empirical evidence suggests that such activities convey bad news to the market. This is consistent with the synergy trap hypothesis and extant empirical findings of value-reducing diversification strategies in recent literature. The evidence also indicates that a cross-border, rather than a domestic M&A deal, is the main driver of the negative market reaction. Furt
Purpose In mobile platforms, an increasing number of third-party developers (developers) create new ideas and enhance their expertise through knowledge sharing on the developers’ community. Notwithstanding the importance of the sharing and its uniqueness on the mobile platform contexts, the motivational factors of sharing their knowledge on the community have been underinvestigated. Therefore, this paper aims to provide a comprehensive framework to enhance the knowledge sharing in the mobile pla
The value chain model serves as a proper analytical tool of industry processes, particularly under rapidly changing telecommunications environments. This article attempts to provide a better understanding of the convergence between the fixed and mobile telecommunication industries by investigating changes in the value chains. Specifically, this article develops a new type of fixed-mobile convergence value chain, and highlights the importance of content and application providers in the new value
