Abstract

This research looks into hedge strategies to resolve foreign exchange-related risks, generated when investing in overseas financial assets, as an example of quantity risk. If an investor has information with no uncertainty over the volume and there is only a price risk he want to hedge, an investor will be able to reduce or eliminate risks by using relative derivative securities such as forwards or futures contracts. However, if there are uncertainties over the volume of hedging targets that is called quantity risk, it is impossible to set the optimal hedge ratio with the traditional method without considering the presence of quantity risk. In this paper, we theoretically draw an optimal hedge ratio which is estimated via minimal variance criterion under static hedge structure. We also analyze its hedge performance and the impact of change in covariance on the optimal hedge ratio and variance of investment return denominated as its own country currency. For theoretical approach, we review the impact that overseas financial assets’ yield and exchanges rates distribution will have on optimal hedge ratio through simple numerical analysis. Empirical analysis is carried out by using the stock indices of the U.S., Europe and Asian countries, and the results indicate that hedge strategies taken with quantity risk for all markets produced better hedging performance than the strategies taken without quantity risk. Since there is a need for systematic research on risks involving foreign exchanges that occur in the event of foreign investments aimed to develop the domestic financial industry, we hope that our research serve as a stepping-stone for further research.

Abstract

Purpose

The purpose of this paper is to examine the relationships between researcher characteristics and their use of metadata in their ResearchGate profiles.

Design/methodology/approach

This paper reports on one part of a larger study that examined researchers’ use of and engagement with research information management systems (RIMSs). The study’s design included qualitative, semi-structured interviews with 15 researchers and a survey completed by 412 researchers. Detailed reports of findings from the interviews and survey can be found elsewhere. This paper reports on the part of the study that analyzed the use of metadata elements in the ResearchGate profiles of 126 survey participants.

Findings

Most researchers shared metadata related to their research rather than their teaching or service. Statistical analyses revealed statistically significant relationships between researchers’ metadata use and their participation levels in RIMSs, as well as between metadata use and researchers’ seniority.

Originality/value

The study’s findings help to identify researchers’ priorities for different metadata elements, as well as to construct profile metadata templates for each specific participation level.

Abstract

There have been several document ranking methods to calculate the conceptual distance or closeness between a Boolean query and a document. Though they provide good retrieval effectiveness in many cases, they do not support effective weighting schemes for queries and documents and also have several problems resulting from inappropriate evaluation of Boolean operators. We propose a new method called Knowledge‐Based Extended Boolean Model (kb‐ebm) in which Salton's extended Boolean model is incorporated. kb‐ebm evaluates weighted queries and documents effectively, and avoids the problems of the previous methods. kb‐ebm provides high quality document rankings by using term dependence information from is‐a hierarchies The performance experiments show that the proposed method closely simulates human behaviour.

Abstract

Purpose

The purpose of this paper is to propose and validate a theoretical model to investigate whether supply chain (SC) innovation positively affects risk management capabilities, such as robustness and resilience in global SC operations, and to examine how these capabilities may improve competitive advantage.

Design/methodology/approach

A theoretical model was developed from extant studies and assessed through the development of a large-scale questionnaire survey conducted with South Korean manufacturers and logistics intermediaries involved in global SC operations. The data were analysed using confirmatory factor analysis and structural equation modelling to validate the suggested model.

Findings

It was found that innovative SCs have a discernible positive influence on all dimensions of risk management capability, which in turn has a significant impact on enhancing competitive advantage. Therefore, this work provides evidence for the importance of SC innovation and risk management capability in supporting competitive advantage.

Research limitations/implications

This study contributes to providing an empirical understanding of the strategic retention of SC innovation and risk management capabilities in the SC management discipline. Furthermore, it confirms and expands existing theories about innovation and competitive advantage.

Practical implications

The finding provides firm grounds for managerial decisions on investment in technology innovation and process innovation.

Originality/value

This research is the first of its kind to empirically validate the relationships between SC innovation, risk management capabilities and competitive advantage.

Abstract

Purpose

The purpose of this article is to furnish empirical evidence on the degree of performance of the 23 major requirements of the ISO 9001:2000 standard implemented at Korean shipbuilding machinery manufacturing companies.

Design/methodology/approach

Deep interviews and surveys were made to measure how well the companies comply with the requirements of the new standard. Correlation analysis, standard t‐tests, and one‐way ANOVA were employed to identify significant differences for each major requirement depending on company size, top management type, implementation motive, and operating period.

Findings

Large‐sized companies achieved compliance with monitoring and measurement better than small‐sized ones; professional manager‐CEOs accomplished compliance with nine major requirements better than owner‐CEOs; companies that certified because of internal development reasons performed compliance with seven major requirements better than those that certified because of customer request; companies with different operating periods showed significant difference in performance for infrastructure, purchasing, and monitoring and measurement.

Originality/value

Adds to the body of knowledge concerning the ISO 9000(2000) version focused on Korean shipbuilding machinery manufacturing companies.

Abstract

Purpose

The purpose of this paper is to examine regional voting patterns in South Korea using the results from six presidential elections since the 1990s.

Design/methodology/approach

A χ2 test was used to determine the municipalities where a regional voting pattern emerged, and λ correlation coefficients were calculated to examine changes in the regional voting patterns.

Findings

The analyses lead to three key findings. First, voting patterns differ in Yeongnam and Honam: regional voting in Yeongnam is getting weaker, it remains strong in Honam. Second, the tendency to vote along regional lines decreased significantly in the election in which the Honam party fielded a candidate with a Yeongnam appeared identity. Third, regional voting patterns declined but then stabilized at a constant level, regardless of the candidates’ local identity, which was confirmed in “Bu-Ul-Gyeong.”

Originality/value

This paper can empirically verify the manifestation of regional voting pattern and confirm the trend. It is possible to derive a condition for suppressing the regional voting pattern.

Abstract

Considering the proliferation of free trade agreements (FTAs) worldwide, this study develops and empirically tests a conceptual model to explain the impact of CEO attitudes on the intention of exporting firms to utilize FTA preferential tariffs. Based on a survey of 221 exporting small and medium-sized enterprises in South Korea, this study employed partial least squares structural equation modelling to test the hypotheses. Results show that perceived usefulness and organizational learning partially mediate the relationship between CEO attitudes and intention to use FTA schemes. This study deepens our understanding on the firm’s internal process for utilizing FTA preferential tariffs.

Abstract

This empirical study examines the psychometric comparability of Aaker's Brand Personality Scale (Aaker, 1997) in sponsorship matching. It employs a structural validation protocol - the congenerity test (Ohanion, 1990) - to investigate the extent to which sports events and sponsors can be psychometrically matched. The results show that sports events and sponsors are comparable only in terms of limited numbers of the dimensions of the a priori scale. Theoretical and practical implications are discussed.
