Once Upon a Time : The Impact of Theming on the Willingness to Pay for Amusement Parks

Habnit, David January 2010 (has links)
<p>This study seeks to find the impact of theming on the willingness to pay of con- sumers for amusement parks. Guests of Finnish amusement park Särkänniemi were asked about their preference for themed attractions and about the price they were willing to pay per ride by means of a questionnaire. Variables concerning both the stated as well as the revealed preference for theming, immersive experience, and previous visits to the park were tested in relation to the willingness to pay for amusement parks. Not all these variables have shown to play an important role; however the variable concerning the revealed preference did have a very strong significance on the willingness to pay in the proposed model. In conclusion the study suggests that the willingness to pay for an attraction is positively influenced by theming because people, as it turns out, are willing to pay more for an attraction when it is themed.</p>

Railway Safety - Risks and Economics

Bäckman, Johan January 2002 (has links)
<p>Safety analysis is a process involving several techniques.The purpose of this thesis is to test and develop methodssuitable for the safety analysis of railway risks and railwaysafety measures. Safety analysis is a process comprisingproblem identification, risk estimation, valuation of safetyand economic analysis. The main steps are described in separatechapters, each of which includes a discussion of the methodsand a review of previous research, followed by the contributionof this author. Although the safety analysis proceduredescribed can be used for analysing railway safety, it has suchgeneral foundations that it can be used wherever safety isimportant and wherever safety measures are evaluated. Itcombines cost benefit analysis with criteria for thedistribution and the absolute levels of risk.</p><p>Risks are estimated with both statistical and risk analysismethods. Historical data on railway accidents are analysed andstatistical models fitted to describe trends in accident ratesand consequences. A risk analysis model is developed usingfault tree and event tree techniques, together with Monte Carlosimulation, to calculate risks for passenger train derailments.The results are compared with the statistical analysis ofhistorical data.</p><p>People's valuation of safety in different contexts isanalysed, with relative values estimated in awillingness-to-pay study. A combination of focus groups andindividual questionnaires is used. Two different methods areused to estimate the value of safety and the results arecompared. Comparisons are also made with other studies.</p><p>Different approaches for safety analysis and methods foreconomic analysis of safety are reviewed. Cost-benefit analysisas a decision criterion is discussed and a study on theeconomic effectsof a traffic control system is presented.</p><p>There are several results of the work. Historical data showsa decrease in the accident rate. The average consequence ofeach accident has not changed over time. The risk analysismodel produces comparable results and enables analysis ofvarious safety measures. The valuation study shows that peopleprefer the prevention of small-scale accidents over theprevention of larger, catastrophic accidents. There are onlysmall differences in the valuation of safety in differentcontexts.</p>

Consumer Willingness to Pay for E85

Skahan, Denise A 01 August 2010 (has links)
Concerns regarding energy security, resource sustainability, and environmental protection have heightened interests in renewable fuels and sparked the research and development of ethanol as a transportation fuel. This study examines consumers’ willingness to pay for ethanol from various potential feedstocks; corn, switchgrass and wood wastes. Data was collected via a survey of fuel consumers across the United States in 2009. Results show that consumers have a preference for E85 (a fuel blend with 85 percent ethanol and 15 percent gasoline) from corn, switchgrass and wood wastes compared to E0 (gasoline) and a preference for E85 from switchgrass and wood wastes, but not corn when compared to E10 (10 percent ethanol and 90 percent gasoline). Also, consumers have a preference for E85 compared to E10 but not compared to E0. Mean WTP for E85 was insignificant across all models, but significant for all other product attributes; percentage of fuel imported, percentage of greenhouse gas emissions reduced, and the proximity of fuel in driving distance. This suggests a WTP for a combination of fuel attributes associated with ethanol rather than just for E85. Results suggest that price and proximity of the fuel have a greater impact on fuel selection than percentage of the fuel imported and reductions in greenhouse gas emissions. Republicans had a positive WTP for E85 compared to E10 and a negative WTP for E85 compared to E0 regardless of feedstock, which may suggest that Republicans actually have no preference for E85; however, these findings may also suggest that Republicans view E85 as a voluntary “policy” whereas E10 is an example of government intrusion in the free market. Thus, they may ultimately have preferences over the manner in which the blend is being introduced to the market. Across all models, those undecided in political affiliation, those previously familiar with ethanol, and those who prefer to devote U.S. farmland to food instead of fuel generally exhibited a lower WTP for E85 while Westerners, those worried about the environment, and those believe that reducing dependence on foreign oil is more important than environmental protection generally had a greater WTP for E85.

Goal Compatibility and Emotional Intensity: An Experimental Study of Graphic Images in Strategic Communication

Klinger, Lauren Marie 01 January 2011 (has links)
The purpose of this quantitative study is to examine receiver variables involved in strategic communications and to look specifically at the use of graphic images in strategic communication materials. It argues that any complete, general model of persuasion effects will include both goal compatibility and emotional determinants. It argues that some influential theories used in strategic communications scholarship, including the situational theory of publics and the elaboration likelihood model, are incomplete because they have omitted these variables. This study also tests variables related to willingness to communicate, behavioral intention, and attitude towards the organization. These variables are drawn from prominent, well-tested theories in strategic communications, and used to begin building a new model of the effects of messages featuring graphic images.

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

Estimation of willingness-to-pay. Theory, measurement, and application.

Breidert, Christoph January 2005 (has links) (PDF)
In this dissertation a new method is proposed to estimate willingness-to-pay (WTP). The method works as an additional interview scene appended to conjoint analysis and it is named throughout this dissertation as the Price Estimation scene (PE scene). In the preceding conjoint analysis price is not included as an attribute. Instead the exchange rate between conjoint utilities and willingness-to-pay is estimated in the PE scene. This is achieved by the use of product stimuli in addition to price scales that are adapted for each respondent in the interview reflecting his or her previously estimated part-worth utilities. In the PE scene the respondents are presented with a sequence of product choices with assigned prices and indicate whether they would actually purchase each of the presented product profiles. The PE scene is a method to estimate willingness-to-pay at an individual level based only on each respondent's provided information. Shortcomings of existing approaches that use conjoint analysis, such as a missing choice rule as well as problems that arise when price is included as an attribute are overcome. The PE scene was tested in an empirical investigation in which the WTPs of the customers of the Nokia online shop in Germany for different product bundles were estimated. (author's abstract)

Factors affecting consumers purchase intentions for digital news : A quantitative study of Resumé

Pettersson, Christoffer, Söderström, Björn January 2015 (has links)
Companies providing digital news are today struggling with low purchase intentions among their consumers. Over the years, the Internet has become a vital part of how people consume news, and the growth in online consumption has led to a decline in printed circulation. Newspapers all around the world are earning only the minor share of their total revenue from digital operations. The main purpose of this study is to investigate the effects of perceived ease-of-use, perceived usefulness, trust, reputation, word-of-mouth, and willingness to customize on consumer´s purchase intentions for digital news. This study aims to answer to the following research question:   What kind of effects do perceived ease-of-use, perceived usefulness, trust, reputation, word-of-mouth, and willingness to customize have on consumers purchase intentions for digital news?   In order to answer our research question, we have conducted a quantitative survey that was directed towards the subscribers of Resumé, the leading Scandinavian business magazine in the area of marketing and advertising. Currently, Resumé is struggling with earning money from their digital content and their practical problem provided us with a great opportunity to contribute to the field of research about digital purchase intentions.   Purchase intentions are an indicator of a consumer´s approach towards a purchase and prior studies demonstrates that perceived ease-of-use and perceived usefulness, which constitute the Technology Acceptance Model (Davis, 1989), are cornerstones in order to predict online consumer behavior. In our study, we also consider willingness-to-customize, which has been found to be an important decision-making factor regarding digital purchase intentions. People’s perceptions of the trust and reputation of a company are also proven to be relevant factors when predicting online consumer behavior, which in turn can be influenced by the word-of-mouth from other consumers, friends and family. Based on our literature review, we can conclude that there is a research gap related to the examination of the effects of these specific factors on consumer´s purchase intentions for digital news.   The findings of our regression analyses, based on 234 responses we received through the survey, demonstrate that perceived ease-of-use, perceived usefulness, and word-of-mouth have positive significant effects on consumer´s purchase intentions for digital news. Based on these results, we have developed a revised conceptual model that includes the three factors that were proven to affect digital purchase intentions. Our study makes a theoretical contribution to the research field about digital purchase intentions and online consumer behavior. The study also provides managerial implications concerning how companies can enhance the digital purchase intentions among their consumers. We suggest the practical recommendations directed towards managers in the digital news business in general, and for the managers of Resumé in particularly.

Laborativ matematik : Vad är syftet? Varför väljer lärare att arbeta laborativt? Vad säger eleverna? / Laboratory mathematics : What is the purpose? Why do teacher chose to use laboratory mathematic? What is the opinion of the students?

Kåresjö, Ida January 2010 (has links)
Research indicates that a more hands-on education in mathematics could improve how students relate to mathematics. Laboratory mathematics is a way of making mathematics more concrete.  How is the purpose of laboratory mathematics perceived? This thesis has its focus on the pupils’ perceptions of the purpose of laboratory mathematics, but the intention of the teacher involved is also investigated. The main research questions asked were: What is the teacher's definition of laboratory mathematics? Which is the teacher's purpose in using laboratory education? How do the students perceive the purpose of the laboratory teaching of mathematics? To answer the questions, I conducted a series of qualitative interviews. Data has been collected in a 3rd grade in Stockholm.  I interviewed a teacher and 17 students.  Results show that the teacher uses laboratory materials to ease the learning of mathematics and to concretize the content of mathematics. By using the phenomenographic method, I got five different preconceptions that students have about the purpose of laboratory education: Laboratory mathematics is for students who have difficulty with mathematics, laboratory mathematics allows more concentration in the classroom, using laboratory materials makes it easier to calculate, laboratory mathematics will help me when I calculate mathematics in every day situations and, finally when I use laboratory mathematics, I work with my hands. The study reaches the conclusion that teachers need to a highlight better the pedagogic purpose for the pupils to use laboratory mathematics.  Laboratory mathematics is in need of a higher status so that more students want to work with laboratory materials.
