Complexities in the valuation of natural resources and the development of the choice modelling techniqueRolfe, John, Economics & Management, Australian Defence Force Academy, UNSW January 1998 (has links)
The Choice Modelling technique is an emerging technique which appears to have strengths relative to other non-market valuation techniques. The latter group are important in the assessment of the tradeoffs involved in environmental and resource use tradeoffs. However, the use of these techniques is often criticised where ethical and moral frameworks are involved, where it is unclear how difficult choices are being framed against each other, or where it is unclear how values change according to the scope of the amenity under consideration The primary focus of the thesis is on the development of the Choice Modelling technique, which provides a richer information set to researchers than other techniques such as Contingent valuation method. However, the richness of this data is offset to some degree by the complexity of application, where careful attention is needed for design, application and analytical stages. In this thesis, a series of four Choice Modelling experiments are reported, as well as two small Contingent Valuation experiments. The Choice Modelling experiments were centred on the estimation of values that Australians might hold for rainforest conservation in Vanuatu. In order to frame and scope the tradeoffs of interest within the broad pool of substitute goods (such as rainforest conservation opportunities in other countries), the Choice Modelling technique appeared more suitable than the single tradeoff preservation of the Contingent Valuation method. The results of Choice Modelling experiments involved sets of parameters indicating that the probability of choice depended on a number of attributes used to make up the conservation profiles together with the influence of unobserved attributes. As a willingness-to-pay variable was included within the attributes making up choice profiles, estimates of value were available by predicting how changes in particular attributes could be offset by changes in the willingness-to-pay variable. The major conclusions of the research presented in the thesis were that the involvement with ethical and moral frameworks does not invalidate the use of non-market valuation techniques, and that the Choice Modelling technique has strengths in relation to scooping and framing issues. In particular, the research demonstrates that the information generated from an experiment can be used in an iterative approach to develop more accurate models of choice. As well, the research shows that the amenity of interest, rainforest conservation in Vanuatu, can have positive values for Australian residents relative to other conservation opportunities.

Provision of environmental goods on private land: a case study of Australian wetlandsWhitten, Stuart Max, Business, Australian Defence Force Academy, UNSW January 2003 (has links)
The management of natural resources located on private lands often involves a perceived conflict between the mix of private and public benefit outputs they produce. Governments have tended to respond through legislation to restrict and redirect private decisions about resource management. However, the legislative response faces a lack of information about the costs and benefits of alternative management and policy instruments. A pertinent example of this debate is the management of wetlands on private lands. The goal in this thesis is to advance the design of policy relating to the production of environmental outputs on private lands. This goal is achieved by first estimating the welfare impacts of alternative private land management strategies on the wider community. These estimates are used as inputs into the development of alternative policy instruments that are then evaluated in terms of their potential cost-effectiveness in influencing private management. Two case studies of wetland management on private land in Australia are presented ??? the Upper South East Region of South Australia, and, the Murrumbidgee River Floodplain in New South Wales. The conceptual approach described in the first part of the thesis includes a description of the resource management problem and the strengths and weaknesses of the alternative decision frameworks widely employed in Australia. Identification of the cause and nature of transaction costs in the management process is the focus in this discussion. The welfare impacts of alternative wetland management strategies are investigated through the construction of a bio-economic model for each of the case study areas. The approach integrates biophysical analysis of changing wetland management with the value society places on wetlands. Outputs from this process are used in the development of a range of policy instruments directed towards influencing wetland management. The impact of poorly quantified and uncertain transaction costs on the potential cost-effectiveness of these options is evaluated using threshold policy analysis. The empirical results show that the perception of a conflict between the private and public values generated by resource management is accurate. For example, scenarios changing wetland management in the Upper South East of South Australia on the Murrumbidgee River floodplain in New South Wales were shown to generate net benefits of $5.2m and $5.1m respectively. Hence, changing wetland management could generate increased community welfare. The potential for these findings to be translated into wetland policy is less conclusive. Policies directed towards wetland management (in part or in whole) incur a range of transaction costs and deliver differential wetland protection benefits. Ten ???best bet??? policies are identified, but more information is required to determine conclusively whether a net benefit results to the wider community when transaction costs are included.

Environmental management and the international competitiveness of nature-based tourism destinations : the case of Tropical North QueenslandHuybers, Twan, Economics & Management, Australian Defence Force Academy, UNSW January 2001 (has links)
The natural environment is a key attraction for Australia???s tourism industry. In order to prevent the deterioration of the environment, environmental management measures have been adopted by the tourism industry. Some of these measures are related to environmental regulations imposed on tourism operators by governments. However, given the dependence of the nature-based tourism industry on the environment, voluntary environmental management measures have also been instituted. The objective of this thesis is to investigate the effect of environmental management on the competitiveness of a nature-based tourism destination. For that purpose, Tropical North Queensland, a major Australian nature-based destination, is selected as a case study. Competitiveness is measured by the aggregate profitability of the tourism industry in the destination region. The investigation incorporates an assessment of the simultaneous effects of environmental management on the destination???s tourism demand and on business costs to tourism operators at the destination. The conceptual background to the investigations is discussed in the first part of the thesis. It includes the rationale for choosing a nature-based destination region as the unit of analysis. The conceptual framework is a departure from the conventional analysis of the relationship between the environment and international competitiveness in which the effect of regulatory compliance costs is emphasised. In this thesis, the potential demand benefits and the associated voluntary environmental management are added to the conventional analytical framework. The primary data for the analysis are derived from two separate investigations. The first comprises an analysis of the tourism industry in Tropical North Queensland. The second investigation involves a discrete choice modelling analysis of destination choices by prospective visitors to Tropical North Queensland. The empirical results show that it is justified to treat the nature-based tourism destination region, Tropical North Queensland, as an aggregate entity in the analysis. The destination competes as a collective unit with other destinations. This is done, predominantly, on the basis of the region???s high-quality natural attractions. The empirical analyses show that tourism businesses??? costs due to environmental management are small in comparison with the positive demand effects. The cost and demand effects are assessed in a quantitative fashion in an economic model. That analysis shows that environmental management makes a positive contribution to Tropical North Queensland???s competitiveness as a nature-based tourism destination.

Demand for genetically modified food : theory and empirical findingsKaye-Blake, William January 2006 (has links)
As economies develop, novel products are created and markets for these products arise. Genetically modified food (GMF) is an example of such a novel product and provides economists with the opportunity to investigate an infant market. Of particular interest with GMF is the impact of consumer reactions on the market. The response of consumers to GMF and their willingness to pay for it has emerged as an important factor in the development of this technology. This research investigates these consumer responses. Prior research suggests that two aspects of consumer behaviour may be relevant for the GMF market. First, consumers may react differently to different types of GMF, so that some products are potentially more economically viable. Secondly, some consumers appear to prefer not having GMF at all. Consumer behaviour is often framed according to neoclassical economic theory. Consumer preferences over goods and the attributes of those goods are generally held to have certain properties. The aspects of consumers' reactions to GMF noted above, however, may be in conflict with two properties of preferences in neoclassical theory. First, preferences over food attributes are not separable, but may interact with each other. Secondly, some consumers may have preferences regarding GMF that are not continuous. As a result, aggregate impacts of introducing GMF may be difficult to measure, which raises a third issue for investigation, aggregation. Finally, an alternative model of consumer behaviour is bounded rationality, which theorises that choices may be discontinuous as a result of specific protocols. It also suggests that consumers seek to make good-enough choices, rather than attempting to maximise their satisfaction. Thus, optimisation or maximisation is the fourth issue considered in this thesis. In order to investigate these properties of consumers' preferences, a choice experiment survey was developed. The strength of a choice experiment for examining these issues is its focus on the impact of each product attribute on a respondent's choices. Thus, it may be possible to identify potentially discontinuous choice patterns and to identify choices affected by interactions between GM technology and other food attributes. Results from a neoclassical analysis of the survey data suggest that some consumers consider the type of benefit created with GM technology in making their choices. In addition, one-quarter to one-half of respondents may have had discontinuous preferences with respect to GMF. Reactions to GMF appear related to respondents' attitudes, but not to socio-economic or demographic descriptors. As a result, aggregate measures of the impact of GMF may not fully account for consumers' responses. A boundedly rational model also has reasonable goodness of fit, and may provide a different perspective on consumer behaviour. It is hoped that the results of this research provide a better understanding of consumer behaviour regarding GMF and, by extension, of the process of consumer adoption of novel products. It is further hoped that this attempt to incorporate choice protocols into discrete choice analysis will provide a useful example for further research.

Abolishing Stockholm’s Public Transport FaresFuentes, Andrés January 2017 (has links)
The decrease of car emission levels has stagnated in the latter years in Stockholm, Sweden. Since the city’s publictransit system is highly developed via its large access to areas located in the city’s outskirts, it could serve as a tool topartially replace the city's car traffic and reduce emissions. This study therefore aims to examine expected travelbehavior changes from a fare-free public transport system and investigate potential limitations when increasing thepublic transport travel degree in Stockholm. The theoretical background consists of the mode choice theory thatdissects the reasons behind travel habits, and the zero-price effect which explains the effects from abolishing priceswhen purchasing a service product. The methodological approach was conducted through a random probabilitysurvey conducted in a face-to-face mix mode survey interviews in outdoor environments and via computer-assistedtelephone interviewing. The data was then analyzed through MS Excel and SPSS to extract patterns and correlations.The results thereafter implicated preferences from the survey participants implying their desire to primarily reduce orabolish the public transport fares, which would lead to significant travel habits changes among the majority ofrespondents. This would result in a high number of both frequent car drivers and frequent public transit commutersthat would commute more by public transit and drive less.
