Value-based Business Strategy

This paper offers an exact definition of the value created by firms together with their suppliers and buyers. The "added value" of a firm is similarly defined, and shown under certain conditions to impose an upper bound on how much value the firm can capture. The key to a firm's achieving a positive added value is the existence of asymmetries between the firm and other firms. The paper identifies four routes ("value-based" strategies) that lead to the creation of such asymmetries. Our analysis reveals the equal importance of a firm's supplier and buyer relations. Cooperative game theory provides the underpinnings of the analysis.     

Value in business markets: What do we know? Where are we going?

This article presents a review of the existing literature on value in business markets, from the perspective of both business marketing and purchasing and supply management, in three steps. First, some of the early research strands on value are examined including value analysis and engineering, the augmented product concept, consumer values, and economic value of customers. Then this seminal research and more recent research are categorized according to two distinct levels of analysis: the value of goods and services versus the value of buyer-supplier relationships, and different understandings of the role of business marketing and purchasing and supply are discussed. Lastly, a number of future research avenues, which can be organized around the value of products/relationships on the one hand and value analysis/creation/delivery on the other, are considered.     

Assessing the externalities of electricity generation in the Midwest

This paper summarizes the research strategy adopted in developing separate estimates of environmental costs for two major private utility systems. One of the systems, North States Power Company in Minnesota, is used to describe the model structure. Particular focus was given to developing methods to assist in the transfer of damage function and monetary valuation estimates to other locations and contexts.     

Fungibility and the impact of development assistance: Evidence from Vietnam's health sector

The apparent fungibility of aid is a challenge to the evaluation of donor-funded development projects, requiring a comparison of the observed outcomes with the outcomes that would have occurred if the project had not gone ahead. Where projects are targeted on specific geographic areas, counterfactual outcomes in each can differ from observed outcomes because the amount of government spending (gross of aid) differs, the productivity of government spending differs, or both. This paper estimates the benefits of two concurrent World Bank health projects in Vietnam targeted on specific provinces. Estimates are derived from a model linking outcomes (under-five mortality) to government spending before and after the project and in project and nonproject provinces, and are presented for different assumptions regarding fungibility of funds (zero and full fungibility) and the impacts of the project on the productivity of government spending (the project modifies productivity in both sectors equally and in neither sector). The estimated mortality reductions are highly insensitive to the assumed degree of fungibility, but highly sensitive to the assumed productivity effects (the estimates range from 1 to 25%). The wide range reflects the uncertainty due to the lack of a genuine control group of provinces.
