Georges Perrin and the GP cost calculation method: the story of a failure

After the Second World War, a number of costing methods were developed in France in response to the perceived limitations of Rimailho's 'homogeneous sections' method. The common feature of all these methods was the provision of a more thorough analysis of operations through the adoption of techniques which were simple to use. The GP method, developed by Georges Perrin, was the most successful but, despite its many advantages, its success was limited, due to deficiencies in Perrin's communication policy and his network of contacts.     

Mixed duopoly, inefficiency, and public ownership

If a publicly-owned firm has a higher marginal cost than a private firm, partial public ownership may be welfare-improving, if the public firm acts is Stackelberg leader. If the private firm's marginal cost is private information a simple transfer function is truth-eliciting. If the stock market is efficient, the cost of renationalization is “small”.     

What is the role of consensus statements in a risk society?

Abstract

This paper explores the role of consensus statements in a risk society. It uses Beck’s theory of risk to show that scientists have employed consensus statements in order to re-establish faith in science. Through analysing the goals of participants in consensus fora and comparing them to the fora processes, this paper considers how consensus statements and guidelines in public health can be viewed as remedies for the decline in expert trust experienced in the current risk society. To collect data, 25 interviews were undertaken with consensus panel participants from the USA, UK and Australia. Interviewees were from peak national agencies/commissioning agencies and were categorised as policymaker, practitioner and consumer stakeholders. Participants made recommendations for improving consensus processes in order to mitigate perceptions of risk. These were: (1) clearly stated goals; (2) robust, evidence-based and transparent processes of methodological development and participation/deliberation/decision-making; (3) diverse stakeholder representation, including increased consumer participation; (4) transparency about conflicts of interest; and, (5) robust, carefully worded recommendations. Poor-quality consensus statements can further entrench scepticism about the scientific enterprise. While consensus statements can be seen as a tool for moderating perceptions of risk, policymakers and scientists must ensure the integrity, strength and transparency of their research methods. This has the potential to facilitate policy, improve scientific accountability to the public and legitimise processes. While fostering greater trust is not a primary objective for scientists, an increase in legitimacy of process can be an important unintended consequence of improved quality consensus statements and an important antidote to the risk society.
