Notes on contributors

This article establishes a basic framework for a comparative analysis of public management reform around the world in recent times. It focuses on politicians and administrators as ‘drivers’ and/or ‘supporters’ of reform, as influenced by their policy roles and contributions, along with electoral politics and government-legislature alignments. Three models are outlined on the basis of the reform experience of selected countries. The models are then related to various reform initiatives by way of eight propositions. The underlying aim is to provide some guidance for research and understanding of reform in different contexts.     

The Value of Biodiversity in Pharmaceutical Research with Differentiated Products

Biologists and conservation advocates have expressed grave concern over perceived threats to biological diversity. ``Biodiversity prospecting' – the search among naturally occurring organisms for new products of agricultural, industrial, and, particularly, pharmaceutical value – has been advanced as both a mechanism and a motive for conserving biological diversity. Economists and others have attempted to estimate the value of biodiversity for use in new pharmaceutical project research. In this paper we apply a new approach to estimating values: we employ two models of competition among differentiated products. Each model confirms previous findings that the value to private researchers of the ``marginal species' is likely to be small. The models can have very different implications with respect to social values, however. These findings underscore the need for a better understanding of the true meaning of diversity.Resources for the Future     

Corporate Perceptions of the Business Case for Supplier Diversity: How Socially Responsible Purchasing can ‘Pay’

In exploring corporate perceptions of the business case for supplier diversity (SD), this paper reports on a cross-national study of large purchasing organisations (LPOs) that had introduced, or were in the process of introducing, purchasing initiatives aimed at ethnic minority businesses (EMBs). The research investigates how LPOs portray the benefits of this form of socially responsible purchasing and suggests a business case construct based on four component elements. It also highlights a number of contextual factors that appear to have shaped business case rationales. The paper concludes with a discussion of issues of cost and contingent influences affecting SD programmes and points to possible areas for future research.     

Sequential Procurement With Subcontracting

Two symmetric sellers are approached sequentially by fragmented buyers. Each buyer conducts a second-price auction and purchases from the seller who offers the lower price. Winning an auction affects bidding for future contracts because the sellers have nonconstant marginal costs. We assume that the sellers are completely informed, and we study the unique equilibrium that survives iterated elimination of weakly dominated strategies. If subcontracting between the sellers is impossible, the final allocation of contracts is generally inefficient. If postauction subcontracting is possible, the sellers can be worse off, ex ante , than when subcontracting is impossible.
