An activities-based approach to network management: An explorative study

Over the last few decades, the industrial marketing literature and the business network literature have promoted a holistic approach to marketing and provided a framework for understanding interorganizational networks. However, our understanding of how interorganizational networks govern themselves when developing innovations is still limited. Most network management literature does not focus on the activities employed by network actors and/or does not recognize that there may be different modes of network management. This study explores how, why and in which combination network management activities are employed in a network and in doing so proposes a new conceptualization of network management. Using primary and secondary data pertaining to eleven innovation projects, this study reveals how network management consists of combinations of (rather than individual) management activities undertaken to manage a network. This study identifies three distinct modes of network management: basically coordinated, control-oriented and reward-oriented. Moreover, this study proposes that network actors try to match the management mode to their prevailing mental model as well as the type of network (e.g. in terms of project innovativeness).     

Market based price support program: an alternative approach to large scale food procurement and distribution system

In most developing countries of the world, large scale public food procurement and distribution systems (PFDS) have become too expensive for the country governments to support from their own resources. Despite high financial and administrative costs of the programs, the degree of seasonal price stabilization and price support achieved through the activities remain quite low. Using the Bangladesh PFDS as a case study, this research indicates that considerable improvements in price support can be achieved by providing credit to the farmers immediately after the harvest. If the government procurement is reduced by 50 per cent in Bangladesh, and providing 150 per cent of the cost of running PFDS as credit, Bangladesh can improve the farmers' income and achieve better stability of cereal prices at a cost less than one-third of the current costs of the PFDS.     

Market frictions as building blocks of an organizational economics approach to strategic management

This paper shows that market frictions are fundamental building blocks for an organizational economics approach to strategic management. Various organizational economic approaches (transaction costs, property rights, real options, and resource‐based) have distinctive focal problems and emphasize different combinations of market frictions. A wider recognition of the role of market frictions is useful for three main objectives. First, it helps identify an evolving market‐frictions paradigm in strategic management. Second, it shows how two primary questions in strategy of why firms exist and why some firms outperform others and the three primary strategic goals of cost minimization, value creation, and value capture can be better joined and evaluated. Third, different combinations of market frictions can generate new research questions and advance theory development in the strategic management field. Copyright © 2013 John Wiley & Sons, Ltd.     

A network approach to modeling the multi-echelon spare-part inventory system with backorders and interval-valued demand

A multi-echelon inventory system implies the existence of a hierarchy of stocking locations, and the dependence and interaction between them. We consider a multi-echelon, spare-part inventory management problem with outsourcing and backordering. The problem is characterized by deterministic repair time/cost, and supply and demand that lie within prescribed intervals and that vary over time. The objective is to minimize the total inventory and transportation costs. We develop a network model for problem analysis and present a network flow algorithm for solving the problem. We prove that the Wagner-Whitin property, known for the lot-sizing problem, can be extended to the spare-part inventory management problem under study.
