| New Zealand houses are cold, damp, and poorly insulated by international standards. Our substandard housing stock has negative effects on health, quality of life, productivity, winter air quality, energy use and transmission. Investment in home energy efficiency is below the socially optimal level due to information asymmetries, bounded rationality and to some degree, non-excludability. Uptake of government grants for insulation has been very low in some communities, especially by owners of private rental properties. This study examines consumer preferences and perceptions of home energy efficiency technologies for residents of the Waikato region. We use a choice experiment approach to determine willingness to pay by owner-occupiers, landlords and tenants.... |

| Reported in this paper are the findings from two discrete choice experiments that were carried out to address the value of a number of farm landscape improvement measures within the Rural Environment Protection (REP) Scheme in Ireland. Image manipulation software is used to prepare photorealistic simulations representing the landscape attributes across three levels to accurately represent what is achievable within the Scheme. Using a mixed logit specification willingness to pay (WTP) distributions based on the parameter estimates obtained from the individual conditional distributions are derived. These estimates are subsequently adjusted and combined to account for baselines and levels of improvement resulting from the implementation of the REP Scheme.... |

| Climate change is one of the toughest challenges facing the world today. Putting a price on carbon emissions is an important step towards climate change mitigation. A cap and trade system is one of the ways to create a carbon price. The New Zealand Emissions Trading Scheme (NZETS) is the world’s first economy-wide cap and trade system that covers all sectors and all 6 greenhouse gases. Forestry is a major part of the NZETS, allowing foresters to earn carbon credits for new forests planted on and after 1st January 1990 (afforestation and reforestation). At the same time, the NZETS also makes foresters liable for harvesting new forests planted on and after 1st January 1990, and deforesting forests existing on and before 31st December 1989. In this paper, we... |

| The intense process of internationalization of the food market is giving rise to new competitive scenarios. Growing market shares on the part of new export countries, along with other consumer and retail issues, impose different marketing policies for agri-food products. In particular, greater consumer awareness of environmental and health issues is changing the structure of demand for fresh products. In the past, the country of origin and a good quality/price ratio were the main strategic strengths for gaining and maintaining international market shares. Nowadays, market shares are gained by moving towards new product attributes, namely environmental friendliness and food safety. This paper draws attention to new, more successful marketing strategies. The... |

| NPV and LEV are established and common approaches to valuing single rotation and infinite rotation forests respectively, when the rotation age is fixed in advanced. More recently, Real Options approaches have been employed to value single and infinite rotation forests with a flexible harvest age. Under a stochastic timber price process, it has been shown that the valuation of a flexible rotation forest is equal or higher than that of a fixed rotation forest, because a flexible harvest regime delays the harvest if the timber price is not favourable, whereas a fixed harvest regime would proceed to harvest regardless of the price. Often, valuation of fixed and flexible rotation ages are compared using 2 different methods – NPV (or LEV) and Real Options. The... |

| We conducted an online choice survey to inform advice to the Tasman District Council on setting management objectives for multiple uses and values across several catchments. One sub-sample was recruited via a survey company and a second via a public call with prize draw. From a survey with unlabelled choice sets for three rivers, we estimated a separate model for each river. Coefficients for natural character, fish & fishing, local jobs and cost were generally significant and had expected signs. Coefficients on swimming and boating attributes were weak even though 68% and 31%, respectively, of the panel sample reported engaging in these activities. Levels of attributes varied for the three rivers and, together with within-sample variation, made... |

| In discrete choice experiments respondents are generally assumed to consider all of the attributes across each of the alternatives, and to choose their most preferred. However, results in this paper indicate that many respondents employ simplified lexicographic decision-making rules, whereby they have a ranking of the attributes, but their choice of an alternative is based solely on the level of their most important attribute(s). Not accounting for these simple decision-making heuristics introduces systemic errors and leads to biased point estimates, as they are a violation of the continuity axiom and a departure from the use of compensatory decision-making. In this paper the implications of lexicographic preferences are examined. In particular, using a... |

| We review the basic principles for the evaluation of design efficiency in discrete choice modelling with a focus on efficiency of WTP estimates from the multinomial logit model. The discussion is developed under the realistic assumption that researchers can plausibly define a prior belief on the range of values for the utility coefficients. D-,A-,B-,Sand Cerrors are compared as measures of design performance in applied studies and their rationale is discussed. An empirical example based on the generation and comparison of fifteen separate designs from a common set of assumptions illustrates the relevant considerations to the context of non-market valuation, with particular emphasis placed on Cefficiency. Conclusions are drawn for the practice of reporting... |
