STATED WILLINGNESS TO PAY FOR PUBLIC GOODS:   总被引:3,自引:0,他引:3  
Abstract— In the contingent valuation method for the valuation of public goods, survey respondents are asked to indicate the amount they are willing to pay (WTP) for the provision of a good. We contrast economic and psychological analyses of WTP and describe a study in which respondents indicated their WTP to prevent or to remedy threats to public health or to the environment, attributed either to human or to natural causes. WTP was significantly higher when the cause of a harm was human, though the effect was not large. The means of WTP for 16 issues were highly correlated with the means of other measures of attitude, including a simple rating of the importance of the threat. The responses are better described as expressions of attitudes than as indications of economic value, contrary to the assumptions of the contingent valuation method.  相似文献

We find three factors to be associated with use of cost-benefit rules in everyday decisions. These are effectiveness in achieving desirable life outcomes, intelligence, and training in economics. We argue that these empirical findings support the claim that cost-benefit reasoning is normative.  相似文献

Selected empirical research on consultative problem solving is reviewed. Although there is general support for the effectiveness of consultation in resolving a variety of presenting problems and in improving consultees' skills for solving future problems, there is a need for additional methods to facilitate the process. Direct training of consultees in behavior management, communication, and consultation process skills is advocated as one means of attaining this goal.  相似文献

Although consultation researchers and practitioners have called attention to the need for more psychometrically sound instruments, little advancement has occurred in this area. The authors outline key quantitative and qualitative psychometric standards for organizational consultation assessment and evaluation instruments. In addition, a framework and review of several existing questionnaires are presented. Implications for instrument use by practitioners and suggestions for further research are discussed.  相似文献

The recent accumulation of self-report measures of borderline personality disorder (BPD) affords the opportunity to evaluate both the construct validity of the concept and the quality of these measures. This study examines the relationship among three recently developed self-report instruments for assessing BPD from the Personality Assessment Inventory (PAI; Morey, 1991), the MMPI Personality Disorders Scales (MPD; Morey, Waugh, & Blashfield, 1985), and the Bell Object Relations Inventory (BORI: Bell, Billington, & Becker, 1986). Data on the three measures were provided by 119 undergraduate subjects from a southeastern university. A correlational analysis addresses the convergence of these measures of BPD, their divergence from measures of different but related traits, and their independence from variance due to method. Application of the Campbell-Fiske (1959) criteria indicates adequate convergence for all the BPD measures but a lack of discriminant validity for the BORI scales. The fit of the data to a structural model of construct validity is tested using confirmatory factor analysis, and these results are consistent with the hypothesis of a latent borderline trait factor independent of measurement method factors. In sum, the construct validity of the borderline personality concept using self-report methodologies receives support, and a strong association between borderline personality and paranoid phenomena is also suggested.  相似文献

Recommendations for improving consultation research include (a) strengthening consultation analogue research by incorporating “boundary” conditions into research designs and (b) extending the outcome measures used.  相似文献

When parents divorce, grandparents who have bonded with grandchildren may be affected, particularly when denied visitation. In this article the author reviews normative aspects of grand-parenthood and how grandparents are affected by parental divorce. Legal and ethical issues and counseling interventions are discussed.  相似文献

This study examined the effects of children's need for approval (nApp) and a situational variable-frequency of expectancy statements-on children's achievement cognitions and behaviour. We replicated the Dweck and Gilliard (1975) paradigm, but also mea sured children's nApp. Ninety fifth grade boys and girls stated expectancies either prior to each trial, prior to the first and last trials, or prior to the last trial only. We found that although high and low nApp children lowered their expectancies after failure, high nApp children lowered them less than low nApp children. In contrast, persistence was influenced only by the frequency of expectancy statements and not by children's nApp. The results are discussed in the context of the interactional point of view in personality psychology.  相似文献
