Three axioms underpin consumer choice in neoclassical theory: weak order, independence, and continuity. Two of these axioms may not hold, however, for consumers’ choices regarding genetically modified (GM) food. Consumers may evaluate product attributes differently depending on whether the...

Infrastructure systems and services (ISS) are vulnerable to changes in climate. This paper reports on a study of the impact of gradual climate changes on ISS in Hamilton City, New Zealand. This study is unique in that it is the first of its kind to be applied to New Zealand ISS. This study also...

The adoption of environmental management practices is addressed in this paper. The use of consumer behaviour theory and a market research approach is discussed by describing how it was used in the study. Qualitative methods were used to gather data from dairy farmers in four New Zealand...

Common forests in developing countries are valuable sources of raw material supplies, employment and income generation, particularly for low income households. This paper looks at the effect on income and employment when common forest resources have external policies that constrain their use....

Nitrogen leaching from agriculture contributes to contamination of Lake Taupo. Multiple criteria decision making was used to compare fourteen pre-defined farming systems which reduced, or maintained nitrogen losses. Case study participants included three to four each of Maori Incorporation...

This study describes the development of bio economic models examining the economic and water quality impact of various proposed policy options in the Upper Waikato catchment. In the first phase nitrogen emissions are determined for representative farming systems using the Overseer nutrient...

Hendy and Kerr (2005b) find that an emissions charge on agricultural methane and nitrous oxide of $25 per tonne of carbon dioxide (CO2) equivalent would be likely to reduce New Zealand‘s net land-use related emissions for commitment period one in the order of 3%, with full accounting. The...

Recent trend depicts that tomatoes and tomatoes products rank 2nd most important vegetable crop in the United States after potatoes and potatoes products contributing 20 percent of total vegetable production. More-so, tomato is equally ranked 2nd in the United States in terms of production...

The parameters of yield response functions can vary by year. Past studies usually assume yield functions are nonstochastic or ‘limited’ stochastic. In this study, we estimate rye-ryegrass yield functions where all parameters are random. Optimal nitrogen rates are calculated for two yield...
