Policies to promote real-time metering (RTM) require more than showing benefits from more timely responses to variations in cost. They require positive externalities to imply that too few meters would be installed through private transactions. RTM presents no systematic externalities when utilities must serve peak period users, and may present negative externalities under some conditions. Positive externalities are likely when electricity is rationed through blackouts. RTM may or may not increase welfare when peak period wholesale markets are not competitive; a prohibition on RTM might be appropriate in such situations even if metering itself were costless. 相似文献

This paper evaluates the two well-known final waste disposal methods, incineration and landfilling. In particular we compare the social cost of two best-available technologies using a point estimate based on private and environmental cost data for the Netherlands. Not only does our comparison allow for Waste-to-Energy incineration plants but for landfills as well. The data provide support for the widespread policy preference for incineration over landfilling only if the analysis is restricted to environmental costs alone and includes savings of both energy and material recovery. Gross private costs, however, are so much higher for incineration, that landfilling is the social cost minimizing option at the margin even in a densely populated country such as the Netherlands. Furthermore, we show that our result generalizes to other European countries and probably to the USA. Implications for waste policy are discussed as well. Proper treatment of and energy recovery from landfills seem to be the most important targets for waste policy. Finally, WTE plants are a very expensive way to save on climate change emissions. 相似文献

Interactive television has arrived, thanks to substantial technology investments that have been made by Sky and others. It is growing in importance as innovative interactive applications are developed for broadcast programmes (eg the BBCi service and Big Brother), and for advertising — and will develop further when broadband deployment gets to critical mass. Readers should not expect a television-variant of the world wide web, however. This was tried during 2000–2002 in the form of web look-alike, interactive ‘walled garden’ sites, and failed to attract critical mass footfall. The model has evolved and now revolves around interactive content synchronised with broadcast, which offers financial services companies an interesting new way to increase awareness and to differentiate the service presentation. Furthermore, over the next ten years, broadband is expected to usher in a new era of personalised television — in which specialised broadcasts (such as personal pensions advice programmes) can be made available on demand. The observations in this paper are mainly drawn from the UK, where digital television penetration is high; the lessons can be applied more broadly, however, and are relevant to any organisation thinking of promoting its service through entertainment channels. 相似文献

Capacity planning and resource allocation are crucial to the cost-effective delivery of health care services. In this paper, we present an analytic approach based on a modified version of the Holt-Winters multiplicative seasonality forecasting model to determine the frequency distribution associated with a hospital care unit's census. This paper is a follow-up to the census frequency distribution simulation model described in Lapierre et al. (Socio Econ. Plan. Sci. 33 (1999) 25). We demonstrate that our model can provide census frequency distributions equivalent to the simulation model of Lapierre et al. [1], but without the computational effort common to simulation models. 相似文献

This paper examines the 205 insolvent thrifts that were resolved in 1988 and assesses the cost savings obtained by selling
179 of the institutions through assisted acquisitions rather than liquidating them. It is hypothesized that the cost savings
were determined by factors related both to the future viability of the acquired institution and the particulars of the deal
arranged by the Federal Home Loan Bank Board and the Federal Savings and Loan Insurance Corporation. The added value by selling
a thrift is determined primarily by the level of core deposits obtained by the acquired thrift. However, the branch structure
and purchased mortgage-servicing rights should also add franchise value to the firm. In addition to these factors, the analysis
accounts for the tax benefits and other regulator forbearances associated with the deals. Other characteristics of the deals
are also considered. It is found that core deposits, tax benefits, purchased mortgage-servicing rights, average branch size,
and type of acquirer, as well as some other factors, were significant determinants of the cost savings obtained through selling
an institution rather than liquidating it. 相似文献

There has been an extensive body of research conducted into the technical aspects of the just-in-time (JIT) manufacturing methodology, particularly prior to 1990. It is only in more recent times that the focus has turned toward the more subtle people-related aspects. The recognition of JIT as a truly holistic approach to managing manufacturing operations has led to an appreciation of the importance of the role played by the human variable as well as an emphasis on the impact that organisational structure and management style can have on successful operation. This article examines and analyses the content of a wide range of articles related to issues such as: the need for change in corporate culture, the role of organisational structures, factors significantly impacting chances of success, the importance of employee involvement, how best to involve employees, the importance of training, how/whom/when to train, different team-based organisational structures, the impact of changing roles on various levels of the organisation and the appropriateness of particular change management strategies. An overall picture of the current state of thinking on these issues is thus developed and the importance of these factors to the successful implementation and operation of JIT highlighted. Opportunities for further research in this important area are identified. 相似文献
