In the nonparametric measurement of allocative efficiency, output prices are fixed. If prices are endogenous, the overall output in the market determines the allocative efficient point. We develop an alternative semi-nonparametric model that allows prices to be endogenously determined.  相似文献

In 1991, Dannon employees had the choice to stay with their current health care plan or switch to a new plan which offered a lower premium and less hospital cost coverage that better fit the needs of most employees. Both plans were the same in all other respects. Only 25% of employees chose the new lower-premium plan over the old plan. This article reports a collaborative effort between The Dannon Company and Cornell University's Center for Advanced HR Studies to identify the patterns of employee choices, and the effects of those choices on the actual costs that employees incurred. The actual decisions of 287 Dannon employees were examined, and the out-of-pocket costs that they actually incurred in the two years after the plan was introduced were calculated. © 1996 by John Wiley & Sons, Inc.  相似文献

Through research on a sample of the top 2000 charities, the Voluntary Organisations Internet Server (VOIS) revealed the potential for a major initiative to provide the opportunity for voluntary organisations to create a quality brand of information on the Internet by coming together on a collective site. The Internet is an ideal medium for voluntary organisations to get their message across, build relationships and raise funds. VOIS has been designed specifically to facilitate these activities and provide the means to a collective presence. While it is mainly large organisations that are using it at the moment, the Internet represents the opportunity for smaller organisations to have a substantial presence because of its democratic nature. VOIS has utilised the principle of economies of scale in order that all organisations can afford to have a useful presence on the Internet. This paper will examine fundraising activities that are already occurring on the Internet, analyse the strengths of the Internet as a marketing tool, explain how marketers can utilise these strengths and explain how VOIS has tried to facilitate these strengths within the features of its standardised site.  相似文献
