This study investigates an under-developed research area, sports partnership management, to deepen the understanding of the strategic implications derived from a sports club’s partnerships. A relationship perspective to the portfolio framework is employed by considering the complexity of a partnership as the managerial input variable, and the value impact of the partnership as the output variable. It adopts a longitudinal single case study design, allowing aspects of both exploration and explanation through evidence from multiple sources within the organization. The data collection entails a three-phase empirical research process, collecting data from different sources within a professional sports club. Based on a dataset containing two waves of contract data collected in Phase 2 coupled with interviews in Phase 1 and discussions in Phase 3, this research provides three meaningful applications of a partnership portfolio framework. Theoretically, this research provides insights into enhancing the rigor of the operationalization of a portfolio analysis by paying particular attention to the validity of the portfolio framework and its measurement issues. Practically, the study offers a framework for analyzing its partnership portfolio that provides insights into the current status of the portfolio and ways to build, sustain and/or improve the management of their partnerships.

This study aimed to examine the applicability of a portfolio approach to the ecosystem-based fisheries management targeting the large purse seine fishery. Most fisheries are targeting multispecies and species are biologically and technically interacted each other. It enables a portfolio approach to be applied to find optimal production of each species through expected returns and risk analyses. Under specific assumptions on the harvest quota by species, efficient risk-return frontiers were generated and they showed a combination of optimal production level. Comparisons between portfolio and actual production provided a useful information for targeting strategy and management. Results also showed the possibility of effective multispecies fisheries management by imposing constraints on each species such as total allowable catch quotas.

본고의 연구목적은 한국의 국제기업이 실무상에서 환위험관리를 위해 환율예측에 과도히 의존하고 있는 현실에 착안하여 그러한 관행이 외환포트폴리오 관리차원으로 발전할 수 있다면 과연 유효성을 확보할 수 있을 것인가를 실증적으로 분석하는 데 있다. 실증분석결과 통계적 환율예측 방법을 동원하여 최적 외환포트폴리오를 구성하고 적절하게 관리한다면 ① 표본평균을 미래환율에 대한 예측치로 이용하는 경우나,② 환율변동의 무작위성을 가정하고 ±1σ 범위내에서 난수를 발생시켜 예측치로 이용하는 경우보다 제한적이긴 하나 그 사후적 성과가 개선될 수 있으며, 구조변동기 등에도 충격을 흡수할 수 있게 해준다는 것을 알 수 있다. 그러므로 기업의 환위험관리에 있어 순수한 위험회피 전략, 그리고 단일통화를 대상으로 환율예측에 의존하는 환위험관리 등의 관행은 비합리적이며, 외환포트폴리오를 관리함으로써 최소의 위험부담하에서 최대의 수익률을 확보할 수 있도록 환위험 관리전략이 수정되어야 할 것이다.
