There have been many studies concerning the relationships between stock returns and volatilities. Their positive relationship is well known from the theoretical point of view, but not empirically shown. Franch, Schwert and Stambaugh [11] has empirically provided the indirect evidence of the positive relationship betwen expected stock return and expected volatility. However, their study lacks some statistical validity. This study reexamines the relationship using regression diagnostics and GARCH model from an international point of view. The empirical results fall to show the positive relationship between expected stock return and expected volaiility, which contradicts those of France, Schwert and Stambangh [1].

This paper focuses on the relationship between innovation and export performance of technology-based firms in Korea. This study analyses the relationship between innovative activity and firm's performances using a sample of 760 technology-based firms in Korea. As for the firm's performance indicators, export is employed. The empirical results support that innovation has a positive effect on firm's export performance. However, for small and medium firms, the relationship between innovative activity and export performance is an U-shape quadratic form, which shows that small firms takes a minimum innovative expenditure in order to access the abroad market. Also, with product differentiation, innovative firms tends to devot more to domestic market than to abroad market. Therefore, it can be concluded that innovative activity builds market power and accelerates export performance. And product differentiation through advertising expenditure make innovative firms less exporting.

In recent years, most of Supply Chain Management literature has emphasized the importance of information sharing among supply chain partners, but empirical researches are few until now, especially in Korea. The purpose of this study is to develop an empirical model focusing on information exchange among partners in supply chain, and to analyze the main factors influencing the causal relationship between information exchange and performance. Based on cross-sectional questionnaire survey on Korean manufacturing firms, this study analyzed the factors influencing information exchange such as environmental factors, organizational factors, relationship factors, and information characteristics of the sample firms. Our major findings might provide many useful insights for managers in exploring the most efficient system for information exchange among partners in the context of SCM.

We question whether Korean IT managers consider real options to reduce risks of cloud service implementation. This work investigates the impact of technology risk, relationship risk, economy risk, security risk upon the intention of IT managers to utilize abandon & expansion options. We also analyze moderation effect of centralization level of decision making between these risks and the utilization of real options. Using the survey questionnaire, we empirically find that technology risk, relationship risk and security risk have significant effect upon abandon option and technology risk, relationship risk, and economy upon expansion option. We also find the evidence that centralization level moderates some risks and the direction of moderation effect is to offset the effect of risks on intention to utilize real options.

This paper empirically examines the relationship between outward foreign direct investment (OFDI) of Korean manufacturing firms and the servicification of domestic employment using a firm-level panel data. In this study, considering the issue of low productivity in the Korean service sector, we categorize service employment into core and non-core services and investigate their relationship with OFDI using the firm-fixed effects model. The empirical results show that the share of core service employment exhibits a positive correlation with the extensive OFDI. On the other hand, the share of non-core service employment, which is expected to generate relatively low value-added, does not show a significant relationship with the extensive OFDI. When we divide the samples based on host countries and the type of subsidiaries, the impact on servicification varies depending on the technological capabilities of host countries and their participation in global value chains. Our study suggests that Korean manufacturing firm's internationalization strategies may facilitate a transition from labor-intensive employment, like the cases in advanced countries, to technology-intensive employment through OFDI and other means.
