Abstract This article compares various methods for correcting contingent valuation aggregate benefits when the sample is known to be biased. A sample is defined as the population, and response rates are simulated on the basis of a measure of salience. The simulated response rates suffer from nonresponse bias and selection bias. Coefficient and benefit estimates that result from weighting and self‐selection correction approaches are compared with the true coefficient and benefit estimates. Our results indicate that at both low and high response rates the standard approach leads to bias, and either correction approach will reduce the bias in coefficient and benefit estimates. 相似文献

本文扼要阐述了经济全球化发展的前景和潜力,并运用李嘉图模型对全球化可能导致的经济损害作出论证分析进而说明,尽管经济学家在极大程度上趋向于将全球化视为基本良性的现象,但全球化仍然对某些国家(包括发达国家)带来经济损害,及对部分人群可能造成极其痛苦的后果。不过,源自于全球化的不断增长的竞争压力,会加强创新和增长,从长远来看,的确对每个国家有利。 相似文献

This study examines the potential impact of a hypothetical 12 percent investment tax credit on new capital investments that require the introduction of new technology. Firms showed some support for this type of a tax credit. However, the purpose of giving a tax credit for investing in new technology is not simply to give a tax “break” to businesses. The underlying objective is to increase hiring, thereby stimulating employment. This research strongly suggests that this will not happen. The results cast a shadow on the impact of all new technology investments on job creation. 相似文献

The price of parking is often considered an important tool with which to influence transport choice but, since many local authorities have limited control over off-street charges and since parking charges have no direct impact on through traffic, its influence on overall travel demand may be limited. Road user charges, on the other hand, do appear to offer an effective means of influencing overall demand. The problem is that public acceptance of such charges is low unless some obvious “carrot” can be identified. This paper explores the possibility that the removal of parking charges might be that “carrot”. Our analysis suggests that, although the removal of parking charges would reduce revenues and dilute the reduction in demand caused by the introduction of road charges, the combined effect might, in certain circumstances, be more beneficial to the local economy and might still yield a net increase in revenue. Given the incidence of impacts, it also appears that a combined scheme would be more equitable and might stand a greater chance of achieving public acceptance than a more conventional road charging scheme. The paper identifies the circumstances in which a combined scheme might work well and outlines the detailed analysis that would be necessary to confirm this. 相似文献

Cruise tourism continues to grow substantially, even as many other forms of travel stagnate. In this era of increasing worldwide violence against tourists, safety, security, and risk abatement are becoming principal components in travelers' decision-making processes. This work examines the issue of perceived risk and safety and what impact these perceptions have on shopping behavior. The research takes place in Jamaica, a country with a reputation for aggressive vendors. Findings indicate that those visitors who traveled with others spent more time shopping and purchased more. Additionally, it was found that first time visitors express higher levels of discomfort with their surroundings than did repeat visitors, thus inhibiting purchase behavior. Finally, it was found that levels of perceived risk and security did have an impact on a traveler's intention to return to Jamaica. 相似文献

Emerging market experience over the past two decades has revealed the tenuous links between external financial integration and faster growth, and the proclivity of such integration to fuel costly crises. Emerging markets learned, converging to the middle ground of the macroeconomic trilemma. Following their crises of 1997–2001, emerging markets added financial stability as a goal, self‐insured by building up international reserves, and adopted a public finance approach to financial integration. The global crisis of 2008–09 illustrated that the advanced economies “overshot” the optimal degree of financial deregulation, while the resilience of the emerging markets validated their public finance approach to financial integration. 相似文献

This longitudinal study explored the relationship between perceived breast cancer risk and worry. We measured both absolute and comparative risk perceptions, and also used the Gail algorithm to assess the accuracy of participants' risk perceptions. Three hundred and one women ages 40–75 participated in a two‐part study assessing how format of breast cancer risk presentation affected perceptions of risk. Relative to their Gail scores, women were biased pessimistically about their own absolute breast cancer risk and yet largely accurate about their comparative breast cancer risk. Perceived comparative risk, but not perceived absolute risk or biases in absolute or comparative risk, predicted subsequent worry. Worry predicted subsequent perceived absolute risk and biases in absolute and comparative risk. These results suggest that women's emotional reactions to breast cancer risk are based on accurate (unbiased) perceptions of their comparative risks. In turn, greater worry prompts a re‐evaluation of absolute risk as well as changes in risk biases. Implications for screening are discussed. 相似文献
