During the Reagan administration, the federal government mandated the use of cost–benefit analysis (CBA) for regulatory decisions involving $100 million or more. While the use of CBAs has increased, less attention has been given to CBA processes involving smaller expenditures (regulatory and nonregulatory). As the federal budget tightens in the years ahead, the need to make hard decisions about these policies, programs, and technologies will increase. This paper describes a CBA process developed for the Office of Strategic Planning of the Social Security Administration; it was designed to handle small-to-moderate expenditure decisions (or for preliminary estimates of larger undertakings). A sample CBA using this process is provided, along with a discussion of the lessons that were learned from an initial application.  相似文献

This opportunistic research has been made possible by the financial crisis that struck much of Asia in 1998, and was followed by a rapid recovery in 1999. Previous research has been conducted to study the structure of family decisions in Korea during the 1997–98 period. By adding one more set of data points, for 1999, it is possible to conduct a 3‐year, longitudinal study to revisit the structure of family decision making under the impact of the economic crisis experienced during this period. The major finding is that more joint decision making occurs under economic stress, although the effect is mitigated by the economic circumstances of the respondent and involvement level of the product category. © 2003 Wiley Periodicals, Inc.  相似文献

The NSW Government is implementing a financial framework which is designed to encourage government service providers to become more efficient and effective. NSW Treasury is using Data Envelopment Analysis (DEA) to measure the efficiency of major government service providers, such as police, courts and hospitals. This paper outlines the progress in implementing the new financial framework and illustrates the way NSW Treasury will use DEA to help improve the efficiency of government service providers by describing an analysis of the NSW Police Service. The results suggest that NSW police patrols (local police districts) could, on average, reduce input usage by 13.5 percent through better management, and by 6 percent if the patrols could be restructured to achieve the optimal scale. Results also indicate that differences in operating environments, such as location and socioeconomic factors, do not have a significant influence upon the efficiency of police patrols.  相似文献

This article has attempted to outline the antecedent conditions which produced a gasoline shortage in the United States and describe the demarketing strategies employed by Shell and Exxon. The effectiveness of their respective strategies and the oil industry, in general, in stimulating de-consumption was also examined.  相似文献

The number and rate of development of new consumer legislation necessitates the evaluation of existing legislation. This paper summarizes and categorizes, in detail, the impact of select pieces of consumer legislation on consumer decision making. It is an implied objective of the paper to provide a perspective for future public policy formulation. The pieces of legislation evaluated in the paper are: (1) unit pricing; (2) product labeling; and (3) disclosure of interest rate provisions for consumer credit. The impact of these pieces of legislation have been minimal, indicating the need for an educational program for consumers.  相似文献

The U.S. income tax system has long been recognized as a hybrid of an income and consumption tax system, with elements that do not fit naturally into either pure system. What it actually is has important policy implications for, among other things, understanding the impact of moving closer to a pure consumption tax regime. In this paper, we examine the nature of the U.S. income tax system by calculating the revenue and distributional implications of switching from the current system to one form of consumption tax, a modified cash flow tax.  相似文献

Air transportation is a key strategic asset in that it provides access to markets and thereby enables the economic development of nations. Thus, in order to maintain their competitiveness in a global economy, countries must invest in air transportation infrastructure to ensure their ability to meet current and future demand for aviation services. The objective of this paper is to develop and illustrate a methodology for evaluating the strategic value of air transportation infrastructure, in particular the benefits associated with the ability to react quickly to changes in the market. The hypothesis is that by recognizing and taking advantage of this strategic value, it may be possible to design better policies for aviation infrastructure delivery.The methodology developed here uses system dynamics to model different strategies for infrastructure delivery. These strategies are defined by three variables: the amount of capacity increase, the time to deliver the capacity and the congestion threshold that triggers the need for capacity delivery. Monte Carlo simulation is used to take into account multiple sources of uncertainty. The model shows that a strategy of capacity delivery based on small increments and short response times can yield more benefits than strategies that consider large capacity increases and long response times. Furthermore, in the specific airport example considered here, it was found that a congestion threshold of 75% should be the trigger for capacity enlargements if strategies based on small capacity increments and 1 or 5 years to increase capacity are considered. The lesson for decision-makers is that congestion delays must be addressed with foresight.  相似文献
