Does corporate diversification reduce value in high technology firms?

We find that firm value is reduced via industrial diversification and this reduction in value depends upon a firm’s technology intensity. We consider that asymmetric information problems are more severe in technology intensive industries and find that high tech industry firms present distinctly larger value reduction when compared to low tech industry firms. The negative valuation effect is greater for firms that have a relatively larger amount of intangible assets and greater R&D capital. We determine that our findings are robust to different estimation methods and alternative excess value measures.     

An Analysis of Trade Patterns and the Effects of the Real Exchange Rate Movements in East Asia

This article investigates the patterns of vertical specialization in trade among China, Japan and Korea, and the effects of real exchange rate fluctuations under a multistage production process. By extending the models of Yi (2003, 2010), we derive two distinct features of vertical specialization and test them using Time-Varying Parameter (TVP) VAR. We find that a positive shock to China’s final good consumption increases the intermediate goods trade between Korea and China, with expanding magnitude over time. In addition, the positive effect of a real exchange rate depreciation on intermediate goods trade is strengthened through the competitiveness-enhancing channel, with this effect being more pronouncing in Korea-China trade than in Korea-Japan trade.     

Structural Changes in China’s Import Market: A Comparison with Korea’s Exports to China

The article examines the structural changes of China’s import market for domestic demand and the corresponding structural changes of Korea’s exports to China for Chinese domestic demand. Using 8-digit HS code data covering the period 2006–2014 and analyzing the processing steps as well as by industry, this study reveals that while the share of ordinary trade in total China’s imports has increased rapidly, the share of processing trade has decreased continuously since the mid-2000s. The article also shows that Korea’s exports to China is still processing trade-oriented. The slowdown of Korea’s exports to China is because of the concentration on processing trade, intermediate goods, electronics and chemistry.     

Investment opportunities and dividend omissions

This study examines the market's reaction to dividend omission announcements and finds that if dividends are skipped to preserve cash for good investments, investors do not necessarily regard the omission as negative information. Markets penalize firms for dividend omissions only in the absence of a good stream of investments. In addition, the positive relation between investment opportunity and abnormal stock returns around the announcements is stronger when the level of information asymmetry between management and the rest of the market participants is low. Additional tests reveal that good omitters overcome underperformance faster in the post period. Overall, the results suggest that financial markets interpret differently the information conveyed in the announcement of dividend omission depending on the firm's future prospects.     

Why do satisfied customers switch? Focus on the restaurant patron variety-seeking orientation and purchase decision involvement

Company efforts to make customers switch from competitive brands to their own or induce them to repurchase their own brands are very important in their marketing activities and in this regard studies of customer variety-seeking orientation and level of involvement in decision making play a crucial role in explaining customers’ product selection activities. The purpose of this study intends to examine interrelationships among customer satisfaction, loyalty, and switching intent in family restaurants and verify the moderating effect of customer variety-seeking orientation and purchase decision involvement. A total of 305 patrons in Korea participated. The results showed a positive relationship between customer satisfaction and loyalty. Participants expressing a high level of satisfaction were more likely to switch restaurants. Whether customers feel loyalty determines their switching intent. There were moderating effects related to customer variety-seeking orientation in the causal relationships between customer loyalty and switching intent. Limitations and future research directions are also discussed.     

The more others care,the more you share? – Social contagion as a stardom trigger of social media superstars –

Emerging superstars on social media platforms reshape the media landscape. This research analyses social contagion as a stardom trigger of social media superstars (SMS). We argue that in addition to serving as a quality indicator, the number of observed consumers of SMS performances also indicates the suitability of discussing the SMS performances with others. We experimentally manipulated the number of previous views of a YouTube video and find that a high number of previous views significantly increases the perceived quality and the video’s discussion suitability even when holding all objective video characteristics constant. We discuss implications for aspiring SMS and (online) marketers.     

An alternative bivariate zero-inflated negative binomial regression model using a copula

We propose an alternative bivariate zero-inflated negative binomial (BZINB) regression model based on a copula. The empirical result shows that the proposed model performs better than the existing BZINB models in terms of the maximum log-likelihood and the AIC.
