The Estimate of Benefit of Recreation Resources in Kaohsiung City

Lin, Chi-lin 16 June 2009 (has links)
While considering disposing the priority of various kinds of communal facilities, the cost that must assess benefit and make the investment first, will not just have waste or the improper situation of resource distribution. Seeing that public goods importance that benefit assess, it is market that appraise law develop successively and extensive application, it is a law of appraisal more feasible and with more potentiality among them to assess the law in condition, so this research does deep discussion to this. Because the traditional demand theory has it to limit to the public goods short of marketing, unable to get consumer's appraisal on the public goods, this research attempts to bring the public goods into personal utility function, via the deriving of mathematics and physics, under the same demand principle, give monetary value to the public goods. Set up the compensation demand function of the public wealth, and can lead and pay wishing to pay prices of public goods from this. Utilize the compensating demand function, the valuation of pushing away regarded in order to wish to pay prices as benefit of public wealth of the income. To the increase or reduction of the quantity of the public goods, generally often use WTP or WTA. A lot of theories or positive research, mostly inclined to use WTP to draw benefit value in the past. Because target, tour of benefit numerous, visit offering, the estimate of benefit of recreation resources have model public characteristic of wealth, so this text attempts to use the public wealth promptly, and wide CVM (contingent valuation method) accepted, apply to Kaohsiung on resource of recreation, rest of resource assess, hope via personal inherent attitude and wishing pairs of behavior is it is it visit benefit, rest of resource to assess to come different of partiality, this is a purpose of this research. It is 23.94 yuan that visitors, willingness to pay ,the average amount of money of the maintenance expense, develop some continuously forever by safeguarding local ecological resources and tour industry in collecting the maintenance expense, up to 53% of the visitors and will to pay, the amount of money is 23.94 yuan to like to pay on average. If can collect the charges with 2007, calculate in accordance with 580,591 persons, it is 13,902,586.8 yuan.

Geoscience and decision making for geothermal energy : a case study

Malin, Reed Ahti 25 October 2013 (has links)
In September 2009 exploratory testing of an old geothermal power well caused a blowout at the El Tatio geothermal field of northern Chile. El Tatio is the largest geyser field in the southern hemisphere. The blowout was a paradigm-shifting event for the management of the El Tatio geothermal field and drew attention to the disparity and critical nature of scientific information sharing. This study uses the El Tatio incident as a case study for examining problems of common-pool resource management and geothermal energy development. It explores how differing valuations of geothermal resources resulted in a breakdown of coherent regulation and negative outcomes for all stakeholders. Contingent valuation methods were used to create an elicitive interview process in order to assess how differences in valuation drove these conflicts and negative outcomes. The sharing of scientific information through Decision Support Systems (DSS) is identified as an important element in resolving these conflicts and creating new policies for common-pool resource management. These methods are presented as tools that can be used by stakeholders to find common ground and seek mutually beneficial outcomes. In addition, these tools can help with the critical issue of social perception of scientific data and science driven solutions to these problems. This study posits that the path forward is to ensure not only that scientific data is communicated in modes appropriate to the community and problem at hand, but that the acquisition and interpretation of this data is informed by stakeholder needs. / text

Is WTP an Attitudinal Measure?: Empirical Analysis of the Psychological Explanation for Contingent Values

Ryan, Anthony M., Spash, Clive L. 10 1900 (has links) (PDF)
Contingent valuation has been given a psychological interpretation, by Kahneman and colleagues, that claims willingness to pay bids represent psychological attitudes rather than personal economic valuations. Evidence reported here shows the need to qualify the role of this attitudinal explanation. In contradiction to the attitudinal hypothesis, the decision to bid zero or positive appears to represent a complex psychological appraisal. Furthermore, evidence of bid clustering on currency denominations implies fundamental differences concerning how people respond to a monetary scale. Whether interpreted as charitable contributions or imprecise welfare estimates there are serious implications for how economists interpret and use stated preference responses. (authors' abstract)

Valuing the social cost of air-pollution in Bophelong township / Ismael Maloma

Maloma, Ismael January 2013 (has links)
The aim of this study is to quantify the social cost of air pollution in Bophelong Township. Bophelong is a dominantly Black low-income settlement located on the South-western part of the Emfuleni Local Municipality in the Vaal Triangle. In 2006 the Vaal Triangle was the first region in the country to be declared an Airshed Priority Area in terms of the National Environmental Management Act (39/2004). Economic literature reveals that there is a strong positive correlation between poverty and pollution. It is on this basis that the study provides a theoretical background to poverty and pollution. The study makes use of a Contingent valuation method to elicit respondents‘ maximum willingness to pay for the reduction of air-pollution in the area. The survey questionnaire covers three broad socio-economic categories namely, the demographic profile, labour force profile and the residents‘ attitudes towards environmental issues. The valuation part of the questionnaire makes use of an open-ended questionnaire to elicit the respondents‘ maximum willingness to pay for the reduction of air pollution in Bophelong. The mean willingness to pay for the reduction of air-pollution in Bophelong is estimated at R132 per annum. The annual social cost of air-pollution in Bophelong is calculated by multiplying the mean willingness to pay with the estimated total population. Bophelong‘s total population was estimated at 49 408. The annual social cost of pollution is thus estimated at R6 521 856. The regression analysis shows that several factors positively influence respondents‘ willingness to pay. The analysis shows that education, employment and level of income are positively correlated with the respondents‘ willingness to pay. This study indicates that there is a positive correlation between poverty and pollution. Most of the air pollution that affects the population of Bophelong is generated from domestic sources such as the burning of coal and biomass fuels for VALUING THE SOCIAL COST OF AIR-POLLUTION IN BOPHELONG TOWNSHIP heating and cooking purposes. In order to eliminate the negative impacts of air pollution on the residents of Bophelong the study recommends that authorities must begin by ameliorating the poverty situation in the area. On the main authorities must introduce measures that target domestic sources of pollution. Some of the measures that could be undertaken to reduce the impact of pollution could include: (a) encouraging residents to adopt the more cleaner top-down coal ignition method known as Basa-njengo-Magogo, (b) providing free basic electricity to poor households in the area and (c) ensuring that houses are constructed with thermal comfort in mind, as this will minimise the need for space heating particularly during winter months. / PhD (Economics), North-West University, Vaal Triangle Campus, 2013
