Mixed Bag: Simulating Market-Based Instruments for Water Quality and Quantity in the Upper Waikato

We designed and implemented participatory computer simulations in three workshops in New Zealand's Upper Waikato catchment to learn how market-based instruments (MBIs) might improve freshwater outcomes when managing water and land resources within limits. An Excel-based platform was built to simulate, in stakeholder workshops, the use of transferable permits and user charges for both water quantity and water quality in the Upper Waikato catchment. Each participant managed a hypothetical property in a simplified catchment that included seven farms, a pulp mill, district council, and a hydro - electric company. Based on profit schedules and policy settings, participants made choices about production intensity, land use change and trading of water and/or nutrient allowances. The simulations highlighted the social and cultural context in which MBIs must operate, and how that context influences the outcomes that we can expect from MBIs. Participants found the simulations to be a valuable learning experience

Employing dynamic fuzzy membership functions to assess environmental performance in the supplier selection process

The proposed system illustrates that logic fuzzy can be used to aid management in assessing a supplier's environmental performance in the supplier selection process. A user-centred hierarchical system employing scalable fuzzy membership functions implement human priorities in the supplier selection process, with particular focus on a supplier's environmental performance. Traditionally, when evaluating supplier performance, companies have considered criteria such as price, quality, flexibility, etc. These criteria are of varying importance to individual companies pertaining to their own specific objectives. However, with environmental pressures increasing, many companies have begun to give more attention to environmental issues and, in particular, to their suppliers’ environmental performance. The framework presented here was developed to introduce efficiently environmental criteria into the existing supplier selection process and to reflect on its relevant importance to individual companies. The system presented attempts to simulate the human preference given to particular supplier selection criteria with particular focus on environmental issues when considering supplier selection. The system considers environmental data from multiple aspects of a suppliers business, and based on the relevant impact this will have on a Buying Organization, a decision is reached on the suitability of the supplier. This enables a particular supplier's strengths and weaknesses to be considered as well as considering their significance and relevance to the Buying OrganizationPeer reviewe

A De-biased Direct Question Approach to Measuring Consumers' Willingness to Pay

Knowledge of consumers' willingness to pay (WTP) is a prerequisite to profitable price-setting. To gauge consumers' WTP, practitioners often rely on a direct single question approach in which consumers are asked to explicitly state their WTP for a product. Despite its popularity among practitioners, this approach has been found to suffer from hypothetical bias. In this paper, we propose a rigorous method that improves the accuracy of the direct single question approach. Specifically, we systematically assess the hypothetical biases associated with the direct single question approach and explore ways to de-bias it. Our results show that by using the de-biasing procedures we propose, we can generate a de-biased direct single question approach that is accu-rate enough to be useful for managerial decision-making. We validate this approach with two studies in this paper.Comment: Market Research, Pricing, Demand Estimation, Direct Estimation, Single Question Approach, Choice Experiments, Willingness to Pay, Hypothetical Bia

Defying marketing sovereignty: Voluntary simplicity at new consumption communities

Purpose of this paper: To broaden the scope of or knowledge of collective voluntarily simplified lifestyles in the UK, by exploring whether voluntary simplifiers achieve their goals by adopting a simpler life. Design/methodology/approach: Radical forms of voluntary simplifier groups were explored through participant-observation research. The methodology can be broadly classified as critical ethnography, and a multi-locale approach has been used in designing the field. Findings: Although for some of these consumers voluntary simplicity seems to have reinstated the enjoyment of life, certain goals remain unfulfilled and other unexpected issues arise, such as the challenges of mobility in the attainment of environmental goals. Research limitations/implications (if applicable): This is an ongoing research, however many opportunities for further research have arisen from this study. Quantitative research could be undertaken on the values and attitudes buttressing voluntary simplicity specifically in the UK. The extent to which such communities influence mainstream consumers could be studied both quantitatively and qualitatively. Mainstream consumers’ attitudes to the practices of such communities could prove useful for uncovering real consumer needs. Practical implications: Despite these communities position in the extreme end of the voluntary simplicity spectrum, their role in shaping the practices and attitudes of other consumers is clear. What is original/value of paper: This paper provides new consumer insights that can re-shape policy-making and marketing practice aimed at achieving a sustainable future
