Many surveys of taxpayers in the wake of the fiscal reforms of the 1970's have indicated that frustration with the inefficiency and wastefulness of government is a major motive behind their votes for tax and expenditure limitations. There is a strongly held belief that government can do as much as it is currently doing with much less money. There is also a widespread belief that by reducing the dollar resources available to governments, they will be forced to become less wasteful and more efficient. This paper argues that increased efficiency in local government is an unlikely consequence of the fiscal reform movement. Indeed, lessened efficiency is a more probable outcome.We are indebted to Thomas Anton, Peter deLeon and an anonymous referee for comments on an earlier draft. The authors are, of course, solely responsible for all assertions and any remaining errors. 相似文献

Government budgets are premised on forecasts of revenues and expenditures. These forecasts are subject to both stochastic error and strategic manipulation. Circumstantial evidence in the budgeting literature and in the popular media suggest that government officials routinely bias the forecasts underlying budgets. The research reported here asked three primary questions: To what extent are budget forecasts systematically biased? Why? (Are fiscal and electoral variables systematically related to the magnitude and direction of the biases?) What political and ethical difference do the biases make? From the literature and an analysis of the incentives facing politicians and bureaucrats, we developed hypotheses about budget biases. These hypotheses were tested using time series data for the City of Pittsburgh, Pennsylvania (1941–1983); the City of San Diego, California (1950–1982); and the Pittsburgh (Pennsylvania) School District (1946–1983). In these locales over the periods examined, budgets were systematically pessimistic; revenues were underestimated and expenditures were overestimated. The fiscal and electoral factors hypothesized to account for this pessimism are, however, very mixed in their ability to explain the biases. 相似文献

Modifying and implanting existing RFID-tags into extracted human molars was described previously [P. Thevissen, G. Poelman, B. Puers, M. De Cooman, G. Willems, Implantation of RFID-tag into human molars to reduce hard forensic identification labor. Part 1. Working principle, Forensic Sci. Int. 156 (2006)]. Maximal vertical occlusal load during which the implanted RFID-tags remain active was evaluated in vitro. The temperature dependency of the implanted RFID-tags was studied on the extracted teeth to find out the maximal obtainable temperature before failure and a test with embedded thermistors to verify temperature distributions. The maximal working temperature of the implanted RFID-tags was revealed and gave indications for the set-up of measuring intra oral and intra tooth temperature during the cremation of a human body. Fatigue was induced on the implanted teeth by thermocycling. The results of this investigation showed the need of putting an extra insulating layer around the modified tags before implantation. The different in vitro tests indicated that the implanted RFID-tags can support certain oral and forensic circumstances. 相似文献

This research examines the outcomes of actions taken by members of a residential neighborhood association to revitalize a neighborhood and to make it a safer and more secure place to live. This urban neighborhood association initiated a major planning process in cooperation with city officials. Residents overwhelmingly adopted the plan that included the creation of mini-neighborhoods with a series of gates to moderate traffic flow, increase neighborliness, and reduce crime. An analysis of official data from police crime reports shows that crime was significantly reduced in the neighborhood after the street changes. This reduction in crime was maintained even five years later. Telephone interviews with neighborhood residents indicated that they perceived reductions in traffic, crime, noise and drug offenses for at least five years after the changes. Even though neighborhood cohesion did not increase, it appears that the actions instigated and promoted by neighborhood association members enhanced the quality of life for neighborhood residents. 相似文献
