This study, using a content analysis method, explored whether and to what extent multinational corporate websites targeting different markets are standardized. It also tested three organizational factors – country of origin, company size, and product type – for their potential influence on the level of corporate website standardization. A sample of 52 top US-based multinational companies and 52 Korea-based multinational companies was drawn and a total of 104 pairs of websites for these companies were content-analyzed. Overall, the degree of website standardization was not significantly different between companies based in the two countries. The results suggest that both US and Korean multinational corporations tend to maintain their websites in a similar way when targeting the home and foreign markets. Among the three organizational factors, only product type – B2B versus B2C products and durables versus non-durables – was found to be significantly associated with the level of website standardization. This study makes important contributions to the research literature by offering new information on the current state of multinational corporate website strategies and advancing our knowledge about international marketing communications on the Internet and influencing factors.  相似文献

This paper is the first attempt to analyze Standard & Poor’s unsolicited and solicited ratings by using bond-yield data in Japan. Our findings show that there are differences in firm characteristics between firms seeking solicited ratings and those that receive unsolicited ratings. Firms with solicited ratings have less information asymmetry and are more likely to be owned by foreign investors, generate more revenue from exports, be cross-listed in the US, and have higher firm quality. But, firms with unsolicited ratings pay higher costs for debt, and their bond prices react more strongly to credit-rating changes. Yield spreads for new bonds with unsolicited ratings are higher than those with solicited ratings, because unsolicited ratings have higher information asymmetry, and investors therefore demand higher yields. We find that bond-price reactions to the announcements of unsolicited rating downgrades (upgrades) are negative (positive) and significant, while bond prices do not react significantly to solicited rating downgrades or upgrades.  相似文献

We examine how business group affiliation affects a firm's labor investment decisions. Using data from 2002 to 2014, we find that Korean business group‐ (chaebol‐) affiliated firms make more efficient labor investments than nonaffiliated firms. The positive relation between chaebol‐affiliated firms and labor investment efficiency is attributed to the mitigation of underinvestment in labor. Moreover, chaebol affiliates have higher labor productivity than stand‐alone firms. We further show that both labor sharing among affiliated firms and their easy access to external financing lead to more efficient labor investments for chaebol firms, compared to stand‐alone firms.  相似文献

The number of strategic alliances for R&D activities in the biotechnology industry is sharply increasing. Some studies show that each alliance partner type has different alliance motives, resources and capabilities, organizational structures and cultures, and degrees of competition with partners, which can lead to different performances of strategic alliances. In this regard, this study conducts an empirical analysis of the different impact of each type of alliance partner on technological innovation performance and finds the moderating effect of absorptive capacity and potential competition by categorizing strategic alliances for R&D activities in the biotechnology industry into three types: vertical-downstream alliances, vertical-upstream alliances, and horizontal alliances. This study analyzed 206 Korean biotechnology firms and their strategic alliances for a total of 292 R&D activities. The results of the analysis showed that vertical alliances have a positive impact on technological innovation performance, while horizontal alliances have an inverted U-shaped relationship with technological innovation performance caused by the effect of competition. Additionally, it was confirmed that the R&D intensity of biotechnology firms has a moderating effect of increasing the impact of vertical-upstream alliances on technological innovation performance.  相似文献

We compare the backtesting performance of ARMA-GARCH models with the most common types of infinitely divisible innovations, fit with both full maximum likelihood estimation (MLE) and quasi maximum likelihood estimation (QMLE). The innovation types considered are the Gaussian, Student’s t, α-stable, classical tempered stable (CTS), normal tempered stable (NTS) and generalized hyperbolic (GH) distributions. In calm periods of decreasing volatility, MLE and QMLE produce near identical performance in forecasting value-at-risk (VaR) and conditional value-at-risk (CVaR). In more volatile periods, QMLE can actually produce superior performance for CTS, NTS and α-stable innovations. While the t-ARMA-GARCH model has the fewest number of VaR violations, rejections by the Kupeic and Berkowitz tests suggest excessively large forecasted losses. The α-stable, CTS and NTS innovations compare favourably, with the latter two also allowing for option pricing under a single market model.  相似文献

This study examined the structural relationships among three different dimensions of workplace stressors (customer-related stressor, CRS; work environment-related stressor, WERS; job-related stressor, JRS), negative affectivity (NA), emotional exhaustion (EE), and the negative effect of that strain on customer orientation (CO) in the context of the emotional labor (EL) of frontline employees in the hotel industry. Data were collected from self-administrated questionnaires distributed among frontline employees in room and F&B divisions in Korean deluxe tourist hotels, where EL is intense. The results of the structural equation analysis indicated a positive association between all three workplace stressors and NA and between NA and EE. There was also a relationship in the opposite direction with EE and CO, as hypothesized. The moderating effect of organizational level on the workplace stressors–NA relationships was also confirmed. In addition, in an alternative model, we found that NA partially mediates the relationship between JRS and EE; whereas, NA fully mediates the relationships between CRS/WERS and EE. Practical implications are discussed in detail and limitations of the study and future research directions are also suggested.  相似文献

This paper focuses on an unexplored dimension of fund managers’ timing ability: Market-wide tail risk implied by information in options markets. Constructing the option-implied tail risk, we investigate whether hedge fund managers can strategically time the tail risk through adjusting their exposure to changes of it. Using an extensive sample of equity-oriented hedge funds, we find strong evidence of tail risk timing ability of hedge fund managers. Furthermore, tail risk timing ability brings significant economic value to investors. Top-ranked funds outperform bottom-ranked funds by 5–7% annually after adjusting for risk factors. Our results are robust to various robustness checks.  相似文献

This article empirically explores the effects of oil price on the Korean economy using a Global VAR model. First, we evaluate the average connectedness of oil price with the Korean domestic variables over the precrisis period. We then investigate the time-varying contribution of oil price to the Korean financial and real sectors during and after the global financial crisis through recursive estimation. It is found that the contribution of oil price becomes very large in the case of real exports, equity prices, and real output, but plays a much less prevalent role in the remaining cases. In the meantime, the time-varying contribution of oil price to the Korean economy has not changed during and after the global financial crisis. Interestingly, we find that the Korean economy is affected mostly by overseas financial conditions in the short-term but it becomes more susceptible to oil price fluctuations in the long run, suggesting that Korea’s reliance on energy imports leaves the economy exposed to volatility in energy prices.  相似文献
