Reconciling economic and biological modeling of migratory fish stocks: Optimal management of the Atlantic salmon fishery in the Baltic Sea

The paper puts forward a model of the Atlantic salmon fishery in the Baltic Sea that integrates the salient biological and economic characteristics of migratory fish stocks. Designed to be compatible with the framework used for actual stock assessments, the model accounts for age-structured population dynamics, the seasonal harvest and competing harvesting by commercial and recreational fishermen. It is parameterized for the Simojoki River stock. The socially optimal policy for maximizing discounted net benefits from the fishery within an uncertain environment is determined using a dynamic programming approach and numerical solution method. Our results indicate that substantial economic benefits could be realized under optimal management without compromising stock sustainability.     

Co-evolution of trust and dependence in customer–supplier relationships

The relational and dynamic aspects of interfirm trust and dependence produce a crucial, but insufficiently addressed, challenge for successful relationship coordination. In this paper we concentrate on this issue by examining how trust and dependence co-evolve in customer–supplier relationships. Building on a case study, we develop propositions and a model that illustrates how interorganizational trust and dependence co-evolve through the different phases of customer–supplier relationships and how we may distinguish cooperative and trustworthy actors from those who will behave opportunistically. Theoretical and practical implications are offered.     

Performance through measuring leader's profiles: An empirical study

It is rather typical in organizations that the oldest or the most experienced professionals are taken into the leaders’ positions. However, the expertise in profession does not always refer to good skills in leadership. This phenomenon is recognized both in earlier studies and in this study. Leadership skills can be taught successfully to leaders in duty. The empirical results report from polarized success of organizations according to the leadership behavior. Hence, leadership behavior should be a natural part of performance measurement in order to manage and improve in the area.     

Developing cost management in customer–supplier relationships: three case studies

This study describes cost management development projects in three customer–supplier relationships and analyzes these projects from the perspective of relationships. Differences in suppliers’ objectives, actions taken, and results gained in the projects were found in the explorative study, although the customer's objective was the same in all cases. The use of cost information depended on the balance of power between firms, on the trust between personnel, and on the volume of the firms’ mutual business.
