The precautionary principle ‐ recently added to the French constitution and part of the draft Constitution of the European Union ‐ aims to protect the public from the risks associated with scientific and technological advance by allowing governments to ban any activity deemed to involve risks, even if those risks are unproven. In reality, the precautionary principle itself poses enormous risks of losing the advantages of projects that are banned, of preventing the development of the means by which risk may be ameliorated and of threatening the private property rights that provide the most effective environmental safeguard. 相似文献

Summary. Within the framework proposed by Mussa and Rosen (1978) for modelling quality differentiation, consumers are assumed to make
mutually exclusive purchases. A unique pure strategy equilibrium exists in this case. In this note, we allow consumers to
buy simultaneously different variants of the differentiated good. We call this the “joint purchase option”. The paper proposes
a detailed analysis of price competition when this option is opened: first, we show that either uniqueness, or multiplicity,
or absence of price equilibrium arise, depending on the utility derived from joint purchase relative to exclusive purchase.
Second, we characterize these equilibria, whenever they exist.

Although there are no traditional markets and money prices inthe public sector, consumers and providers may respond to signalsof organisational performance. We present a simple dynamic modelof the demand and supply for elective surgery in the UK NationalHealth Service in which waiting time acts as the prime indicatorof performance. The model is tested using a panel of quarterlydata for 123 English health authorities over an eight-year period.We find that supply is increasing and demand is decreasing inmeasures of the previous period waiting time. The results implythat health care systems which are rationed by waiting do respondto indicators of waiting times. The paper adds to the smallbut consistent body of research which demonstrates that publicsector systems respond to important aspects of reported performance. 相似文献

Universal service and public access in the networked society 总被引:1,自引:0,他引:1
Concern about access to the new services and facilities emerging from the technologically dynamic telecommunications industry and its ‘convergence’ with broadcasting and information technology has resulted in calls for a reconsideration of the nature and scope of Universal Service Obligations (USOs) so that they are more adequate and relevant in an era of technological acceleration towards a networked information society. This paper assesses approaches to upgrading USOs and to developing policies for public access to the networked society undertaken thus far in various OECD countries, and proposes frameworks for conducting the tasks in a systematic manner. 相似文献

The introduction of behavioural insights into policy-making is welcome, because they challenge traditional assumptions in policy-making which are largely inspired by neoclassical economic thinking. In line with good evidence-based policy-making, they make us question and test how people behave instead of assuming we already know the answer. 相似文献
