| The use of riparian land buffers is widely promoted as a method of mitigating the effects of sediment and nutrient runoff from intensive land use in New Zealand. Farmers receive advice and financial assistance from Regional Councils for activities such as establishment and planting of riparian buffers, but funding is limited. The effect of buffers on water quality goals varies across land types so the optimum size of riparian buffer width varies across farms. We build a stylised model to determine the optimum buffer width and apply it to the Karapiro catchment. The model can easily be extended to model salinity removal, conservation reserve programmes, establishing wetlands and carbon sequestration. |

| Water pollution is widely considered to be one of the most important environmental issues facing New Zealand. Waikato region residents have reported that water pollution is easily their most important environmental concern in each of four attitude surveys conducted by Environment Waikato. Technical and regulatory mechanisms to reduce water pollution, especially non-point source pollution from agriculture are the focus of an intensive research effort both in New Zealand and internationally. This work should assist farmers and policy makers to identify the most cost effective options for achieving any given improvement in water quality. Research described in this paper aims to complement existing research projects by developing appropriate methodology for... |

| 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... |

| 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... |

| Trout angling is one of the most popular water-based recreational activities in the Rotorua Lakes. Despite the high demand for trout angling and other recreational purposes, water quality in some of these lakes has been declining over the past decades and initiatives to try to restore the lakes are underway. To compliment these efforts, this study uses the travel cost random utility models to explore how changes in water quality would impact upon angler’s choice of fishing destinations. The welfare impacts due to water quality changes and possible lake closures are also explored. These findings highlight the importance of discrete choice random utility models as a policy decision making tool for recreational-based natural resource managers in New Zealand.... |

| The New Zealand Qualification Authority (NZQA) started to introduce a new qualification; the National Certificate of Educational Achievement (NCEA) in 2002. NCEA level 3 replaced the University Bursary Examinations in 2004. The main purpose of this paper is to investigate the relationship between the number and quality of credits gained at NCEA level 3 by students and their academic performance in a first year economics course - Business Economics and the New Zealand Economy at Waikato University. Other factors that could affect student performance are also investigated. Our analysis suggests that several factors can have an impact on student's performance in ECON100. These factors include nationality, semester, total number of NCEA level 3 credits and the... |

| The agriculture sector in Kazakhstan has undergone rapid change over the last ten years. In the first stage state owned and collective farms were transformed into producer cooperatives owned by their former employees. Central provision of essential inputs was rapidly withdrawn while product prices were initially held down to protect urban consumers. Faced by rising input prices, escalating tax demands and disappearing product markets the cooperatives sold much of their livestock and built up unsustainable levels of debt. In the latest stage of the process, bankruptcy procedures have been used to write off debts and reorganise the cooperatives into private farms. Against this background the paper describes an attempt to assist three farms to draw up... |
