In this paper, we analyze housing‐market reactions to the release of previously unpublished information on school quality. Using high‐quality housing data, which precisely bracket the timing of the information shock, we investigate housing‐price dynamics within school‐catchment areas. We find a robust short‐term housing‐market reaction to the publication of school‐quality indicators, suggesting that this information was new to the households, and that households are willing to pay for better schools. The publication effect does not seem to be permanent as prices revert to pre‐publication levels after two to three months.  相似文献

With charities of all sizes now having the ability to collect and store very large quantities of data about their donors on in‐house database systems, detailed donor performance analyses have an increasingly essential role to play in the effective planning and management of fundraising. If, however, such activities are to support fully the work of fundraisers then it is important that they are undertaken from the perspective of the fundraiser rather than of the specialist data analyst. This paper introduces an approach to donor performance analysis that is founded on what is termed a ‘donor lifecycle model’. The aim of this is to provide a formal analysis methodology that provides end results that can be more easily interpreted by nonspecialists and so more effectively used in support of the efficient planning of fundraising programmes.

Plant-based precision nitrogen fertilizer application technologies have been developed as a way to predict and precisely meet nitrogen needs. Equipment necessary for precision application of nitrogen, based on sensing of growing wheat plants in late winter, is available commercially, but adoption has been slow. This article determines the expected profit from using a plant-sensing system to determine winter wheat nitrogen requirements. We find that plant-sensing systems have the potential to be more profitable than traditional nonprecise systems, but the existing system simulated was roughly breakeven with a traditional system.  相似文献

Industrial research in the United States took hold and grew during much of the 20th century. Bell Labs, a corporate component of the Bell System, was perhaps the premier example. The period from 1925, when Bell Labs was formed, to 1984, when the Bell System was broken up following a government antitrust lawsuit, is of special interest because the system operated as a regulated monopoly during that period. Telephone subscribers effectively paid for research and development in their monthly phone bills, which provided an element of financial stability for the labs. Statistics research was one of many types that thrived, much to the benefit of the Bell System, its customers, and the science of statistics. The purpose of this article is to review, explain, and illustrate the circumstances that contributed to this success and to raise the question of how modern corporations, operating in fully competitive environments, might achieve some of the same benefits.  相似文献

Climate change is an externality problem—so the challenges that arise in limiting it and dealing with the effects that remain are largely fiscal. The structure of the problem, however, and the uncertainty which surrounds it, make the design of proper policy responses particularly complex. This paper provides a primer on the fiscal implications of climate change, the aim being to provide a (reasonably) quick and comprehensive overview of the main analytical issues and lessons learned.  相似文献

In 1993, Californians voted on a school voucher initiative. We hypothesize that homeowners in good school districts understood the voucher to be a threat to their property values and thus voted against it. Precinct returns from Los Angeles County confirm this hypothesis. We also examine an alternative hypothesis explaining the relationship between school quality and precinct returns. According to the alternative, voters perceived the initiative to be a referendum on public school quality. To distinguish between the two hypotheses, we compare the voting patterns of homeowners and renters. The comparison does not favor one hypothesis over the other.  相似文献
