The notion of sustainability has lead to the evaluation of public projects in terms of wider socio-economic and environmental benefits. The Cost Benefit Analysis and its respective, Social Discount Rate (SDR), is of crucial importance, especially when the advantages of private financing are to be demonstrated in comparison with the alternative traditional procurement of works and services. The SDR seen as a measure of a country’s value of future costs and benefits is related to the notion of promoted sustainability. The impact of smaller and declining SDRs on project selection is investigated, and a conceptual formulation concerning the selection of the project procurement method is presented. The modelled formulation will assist central and local governments in assessing projects and the potential benefit of private financing.  相似文献

Technology forcing is a strategy where a regulator specifies a standard that cannot be met with existing technology, or at least not at an acceptable cost. Using the 1970 U.S. Clean Air Act for controlling automobile emissions as a baseline example, we demonstrate the importance of the regulatory implementation process if regulations are to foster technological change. The 1970 legislation required steep emissions reductions for new 1975 and 1976 automobiles, which presented automakers with major technical and economic challenges. Nevertheless, the U.S. Environmental Protection Agency successfully forced the adoption of two marquee control technologies—the catalytic converter in 1975 and the three-way catalyst in 1981. We focus on three factors critical to the implementation process: agency credibility to enforce standards, competitive pressures to drive industry research and development, and uncertainty about technological development.  相似文献

Presents a method for estimating the impact on national development of installation of telecommunication facilities in rural areas of developing countries. A methodology developed by Hardy is applied to three groups of developing countries and a hypothetical rural region to estimate the impact on GDP per thin route satellite earth station installed over a ten year period. A logarithmic relationship between telephone density and impact on GDP per earth station is found, so that the impact per earth station increases with lower telephone densities. The model can be used to estimate the impact on national GDP of telephone installations and/or thin route earth stations in regions of low telephone density.  相似文献

Branding studies, especially those focusing on brand extension, have often centered on establishing the relationship between consumer evaluation and the match between a product concept and the brand (concept congruity). This study introduces an additional type of congruity that arises in the evaluation of co‐branded products, the congruity between brand partners (between‐partner congruity). Between‐partner congruity has not previously been explicitly considered in the co‐branding literature, but is potentially an important influence on consumer perceptions of a brand partnership. Thus, this study represents an initial attempt to understand how the level of between‐partner congruity will affect consumer response to cobranded products. Several findings in the marketing literature have suggested that when respondents have the motivation to resolve incongruity, the relationship between congruity level and evaluation is nonmonotonic. In other words, moderately incongruent concepts are preferred to congruent or highly incongruent concepts to form an “inverted‐U” data function. Yet, when motivation to process is low, evaluation becomes less favorable in a linear fashion as incongruity increases. This study examines whether these findings can be extended to co‐branding. When concept congruity is controlled across brand pairs, the nonmonotonic relationship between between‐partner congruity level and product evaluation is observed when consumers are encouraged to elaborate on the rationale for the partnership (high involvement). However, when consumers attend to the global similarity of the partners (low involvement), product evaluation becomes less favorable as between‐partner incongruity increases. © 2007 Wiley Periodicals, Inc.  相似文献

This paper estimates the quantity of pollutant produced by the Hong Kong hotel industry through diesel oil consumption. A survey of 20 hotels was carried out to collect three years' energy consumption data. Regression analysis indicated that gross floor area was a major and statistically accepted factor in explaining diesel oil consumption. Diesel oil consumption had reduced from the early 1990s and stabilised by the late 1990s. The sulphur dioxide, nitrogen dioxide, carbon dioxide and particulate pollution created by the hotel industry's diesel oil usage from 1990 to 1999 is estimated. The findings indicate that existing green measures and devices are passive and depend on the assimilation of the atmosphere. Environmental costs have stabilised at about HK$54,000 per annum. More proactive approaches to reduce usage and environmental impacts are proposed.  相似文献

Abstract . An empirical analysis of the property crimes, robbery, burglary and larceny, is presented for all 120 counties in Kentucky. While this analysis is based on an economic model of crime, certain sociological and legal variables are included as well in the system of equations. Overall, the empirical results support prior studies’findings with the exception that a quadratic relationship is found to exist between urbanization and each of the property crimes. Furthermore, neither the economic nor the non economic influences measured appear more important for affecting crime rates. Specifically, results indicate that the level of poverty, the degree of tourism, the presence of police, the unemployment rate and the apprehension rate all affect property crimes. In contrast, the length of sentence, the degree of industrialization, the level of public assistance payments and the proportion of youth in the county have no affect on property crime rates in these areas.  相似文献

The fertilizer swaps market is a potential tool to protect against fertilizer price risk. The swaps evaluated here are cash settled using The Fertilizer Index. Hedge ratios and hedging effectiveness are calculated for urea and DAP diammonium phosphate (DAP)) swaps. Urea and DAP swaps perform poorly as a hedging tool over a one-week horizon. As the hedging horizon increases, the hedging effectiveness of swaps improves. The swaps are more effective in mitigating risk across ocean freight routes than across inland routes. The limited hedging effectiveness is due to high spatial basis risk in fertilizer markets.  相似文献

We analyze a model of moral hazard in local public services, which could be efficiently managed by officials under local democratic accountability, but not by officials who are appointed by the ruler of a centralized autocracy. The ruler might prefer to retain an official who diverted resources from public services but contributed part to benefit the ruler. The autocratic ruler would value better public services only when residents reduce taxable investments, which become unprofitable without good public services. For local government to benefit local residents, they must have some decentralized power to punish an official who serves them badly even while serving the ruler well.  相似文献
