On the core of auctions with externalities: stability and fairness

In auctions with externalities, it is well-known that the core can be empty, which is undesirable both in terms of stability and “fairness.” Nevertheless, some auction outcome must be chosen. We separate deviations into two types: deviations by paying more and deviations by refusing to pay. In high-stakes auctions where bidders also care about their reputation, the latter are unlikely to occur, or else can be prevented by legal interventions. In contrast, the former is more undesirable in the sense that the seller and the bidders experience justified envy. We show that the core is nonempty if bidders cannot refuse to pay.

Spatiotemporal distribution of urban walking tourists by season using GPS-based smartphone application

The purpose of this study is to determine urban walking tourists’ spatiotemporal distribution by season. With the Bukchon Hanok Village in Seoul, South Korea, as a study site, a GPS-based smartphone application collects spatiotemporal data from 233 participants, and GIS and statistical methods are used to analyze walking tourists’ spatiotemporal distribution by season. The main results of difference analysis show that the moving and staying variables of urban walking tourists differ significantly by season. In addition, spatiotemporal distributions using ArcGIS's tools show clear spatial and temporal concentrations along commercial areas and the main access road to the study site by season, while residential areas are isolated from the benefits of walking tourism. Policy-makers and planners of walking tours should use these unbalanced spatiotemporal distributions of walking tourists to define policies that would distribute tourists spatially and temporally, thereby decreasing conflicts arise between stakeholders.     

How does CRM technology transform into organizational performance? A mediating role of marketing capability

Customer relationship management (CRM) technology has attracted significant attention from researchers and practitioners as a facilitator of organizational performance. Even though companies have made tremendous investments in CRM technology, empirical research offers inconsistent support that CRM technology enhances organizational performance. Given this equivocal effect and the increasing need for the generalization of CRM implementation research outside western context, the authors, using data from Korean companies, address the process concerning how CRM technology translates into business outcomes. The results highlight that marketing capability mediates the association between CRM technology use and performance. Moreover, a customer-centric organizational culture and management system facilitate CRM technology use. This study serves not only to clarify the mechanism between CRM technology use and organizational performance, but also to generalize the CRM results in the Korean context.     

Measured anxiety affects choices in experimental “clock” games

We measure anxiety by skin conductance response (SCR) in an economic setting. In “clock” games, six agents receive private signals when an asset's price exceeds its fundamental value. They can sell for immediate value or wait to sell at a higher value. Waiting is risky because the price crashes to a lower value when three agents sell. Anxiety could lead people to sell too quickly when the game is played dynamically over time, compared to a static version with precommitted selling. Empirically, delays are shorter in dynamic games than in payoff-equivalent static games, and are associated with anxiety as measured.     

Permanency of CSR Activities and Firm Value

So far overlooked by the international business ethics literature, we introduce, characterize, and normatively analyze the use of affective ties and networks in South Korea from an ethical point of view. Whereas the ethics of using Guanxi in China has been comprehensively discussed, Korean informal networks remain difficult to manage for firms in South Korea due to the absence of existing academic debate and research in this field. In this study, we concentrate mainly on the question of whether foreign firms will and can use affective ties in Korea. The informal social network forms are classified and contrasted with the conventional ethical approaches used in international business ethics (relativism, universalism, and social contract theory) to assess which categories can be regarded as ethical or unethical. Finally, foreign firms are advised how to cope with and use different affective network types. Although the nature of affective ties and networks in Korea differs from that found for instance in China (Guanxi), consistent with the conclusion of prior research, we recommend particularistic analysis and decision making regarding the circumstances in which to conclude affective ties and networks and when to opt out. We conclude that foreign firms in Korea should invest in establishing Inmaek, refrain from engaging in Yonjul, and support host country nationals’ Yongo ties. Moreover, it is suggested that foreign firms should find ways to monitor and manage informal ties effectively.     

Competition,product line length,and firm survival: evidence from the US printer industry

Adjusting product line length is one major strategy that firms employ to sustain their market position in competitive environments. This study extends extant literature on product line length by adding empirical results on the relationship between competitive intensity and product line length, and by examining the performance of firms that follow the suggested product line strategies. The analysis of data on 1849 printer products introduced by 342 manufacturers from 1983 to 2002 shows an inverted U-shaped relationship between competitive intensity and product line length, and firms following this pattern have a significantly lower hazard ratio of exit. These results confirm those discussed in the previous literature and provide evidence of the positive impacts of following such product strategies on firm survival.     

The Value-relevance of Earnings and Book Value, Ownership Structure, and Business Group Affiliation: Evidence From Korean Business Groups

Abstract:  We investigate the quality of two primary accounting summary measures, i.e., earnings and book value, provided by firms belonging to Korean business groups (chaebols). We find that the value-relevance of earnings and book value is significantly smaller for firms affiliated with business groups. We also find that cross-equity ownership (a proxy for the agency problem between controlling and minority shareholders) negatively affects value-relevance, while foreign equity ownership (a proxy for the monitoring effect) positively affects value-relevance. This evidence is consistent with the view that the poor quality of earnings and book value provided by chaebol-affiliated firms is due to the inherently poor governance structure of chaebols.
