A review of Multi-Agent Simulation Models in Agriculture AgEcon
Kaye-Blake, William; Li, Frank Y.; Martin, A. McLeish; McDermott, Alan; Neil, Hayley; Rains, Scott.
Multi-Agent Simulation (MAS) models are intended to capture emergent properties of complex systems that are not amenable to equilibrium analysis. They are beginning to see some use for analysing agricultural systems. The paper reports on work in progress to create a MAS for specific sectors in New Zealand agriculture. One part of the paper focuses on options for modelling land and other resources such as water, labour and capital in this model, as well as markets for exchanging resources and commodities. A second part considers options for modelling agent heterogeneity, especially risk preferences of farmers, and the impacts on decision-making. The final section outlines the MAS that the authors will be constructing over the next few years and the types of...

Agricultural Environmental Indicators: Using OECD Agri-Environmental Indicators to Assess New Zealand Kiwifruit Orchards AgEcon
Saunders, Caroline M.; Kaye-Blake, William; Campbell, Rachel; Benge, J..
Agri-environmental indicators (AEIs) developed by the OECD have been used to assess the environmental performance of the agricultural sector in developed countries. The Agricultural Research Group on Sustainability (ARGOS) in New Zealand has investigated using these AEIs to assess the performance of individual kiwifruit orchards. ARGOS is following panels of orchards to investigate the impacts of organic and conventional management systems on economic, sociological, and environmental dimensions of farming. The environmental monitoring of these orchards has provided data for calculating AEIs. The paper discusses the performance of ARGOS orchards, the impact of management systems, and the implications for future research.

Analyzing Drivers of World Food Prices: Weather, Growth, and Biofuels AgEcon
Saunders, Caroline M.; Kaye-Blake, William; Cagatay, Selim.
The recent rise of food cost in world markets has accelerated the research examining the underlying factors for this rise. The present research investigated the separate and combined impacts of three factors thought to contribute to the price rise: adverse weather events, strong and sustained growth in high populated countries, and increased biofuels production. The research further analysed the effects of these price rises on consumption expenditures in Brazil, China and India. Analyses were carried out using a partial equilibrium trade model with a focus on the 2004 to 2007 period. The modelling suggests that the most important factor behind the price rise depends on the commodity, with maize/corn, oilseeds, and sugar most affected by biofuels, while...

Capital Based Sustainability Indicators as a Possible Way for Measuring Agricultural Sustainability AgEcon
Saunders, Caroline M.; Kaye-Blake, William; Campbell, Rachel.
This paper takes the capital based approach to sustainability and applies this to examine the sustainability of different farming methods. The capital based approach argues that for future generations to be as well off as the present than the capital base should at least be maintained. The paper explores some of the issues around this approach such as the definition of capitals, their measurement and weakness in the approach which do not account for the resilience of system and/ or the substitutability of capitals. The paper outlines how this could be applied to agriculture and show sustainability across different farming methods. The data used is from the ARGOS (Agricultural Research Group on Sustainability) project which has collected data on social,...

Comparative Performance of Organic, Conventional, and Integrated Producers in New Zealand AgEcon
Greer, Glen; Kaye-Blake, William; Hunt, Lesley.
The Agriculture Research Group on Sustainability (ARGOS) monitors a wide ange of environmental, social, economic and management parameters on matched cohorts of organic, conventional and integrated farms in the sheep/beef and kiwifruit sectors. Over six years significant differences have been found in farm costs and revenues between management systems, but few differences have been identified between management systems in “bottom-line” indicators of profitability, and there is greater variability within cohorts than between them. Regrouping of the properties according to farmer typologies does, however, result in the identification of some significant differences in economic outcomes between different “types” of farmers.

Consumer Attitudes towards Sustainability Attributes on Food Labels AgEcon
Tait, Peter R.; Miller, Sini; Abell, Walter L.; Kaye-Blake, William; Guenther, Meike; Saunders, Caroline M..
Concerns about climate change and the general status of the environment have increased expectation that food products have sustainability credentials, and that these can be verified. There are significant and increasing pressures in key export markets for information on Greenhouse gas (GHG) intensity of products throughout its life-cycle. How this information is conveyed to consumers is a key issue. Labelling is a common method of communicating certain product attributes to consumers that may influence their choices. In a choice experiment concerning fruit purchase decisions, this study estimates willingness to pay for sustainability attributes by consumers in Japan and the UK. The role of label presentation format is investigated: text only, text and...

Consumer attitudes towards sustainability attributes on food labels AgEcon
Saunders, Caroline M.; Guenther, Meike; Kaye-Blake, William; Miller, Sini; Tait, Peter R..
With current concerns about climate change and the general status of the environment, there is an increasing expectation that products have sustainability credentials, and that these can be verified. Labelling is a common method of communicating certain product attributes to consumers that may influence their choices. There are different types of labels with several functions. The aim of this study is to investigate consumers‟ purchase decisions towards certain sustainability claims on food products, particularly by displaying the reduction of carbon emissions. Choice outcomes will be evaluated using Discrete Choice Modelling (DCM). Data for the study is obtained by a web-based consumer survey undertaken in the United Kingdom (UK). Results provide...

Current Contribution of Four Biotechnologies to New Zealand's Primary Sector AgEcon
Kaye-Blake, William; Saunders, Caroline M.; Emanuelsson, Martin.
Over the last several decades, changes to production technologies have significantly increased output from the primary sector. The contribution of improved genetics has been variously estimated, and the impacts of genetic engineering have received much attention. The present research estimated the economic impact of four modern biotechnologies (other than genetic engineering) on the primary sector. Information from interviews with key informants was incorporated into a cost-benefit analysis to estimate these impacts. The net contribution was estimated at $266 million per year, with impacts spread unevenly through the sector and across biotechnologies.

Estimated Contribution of Four Biotechnologies to New Zealand Agriculture AgEcon
Kaye-Blake, William; Saunders, Caroline M..
The impact of biotechnology is an important consideration for New Zealand. The country depends significantly on agricultural production and exports (Ministry of Agriculture and Forestry, 2004), and has relied in part on modern biotechnology for productivity increases over the last 20 years (Evenson & Gollin, 2003; Jacobsen & Scobie, 1999; Ovenden, Anderson, Armstrong, & Mitchel, 1985). A recent survey of individuals in agriculture and biotechnology generated a comprehensive list of products and processes that are derived from four specific biotechnologies and are commercially significant in agriculture (Kaye-Blake, Saunders, Emanuelsson, Dalziel, & Wreford, 2005). This innovative research generated primary data on the actual impacts that...

Modelling Climate Change Impacts on Agriculture and Forestry with the Extended LTEM (Lincoln Trade and Environment Model) AgEcon
Saunders, Caroline M.; Kaye-Blake, William.
In the land-based sectors, agricultural production generally is a source of carbon, while forestry may be thought to act as a sink. This paper focuses on new research examining the interaction of the two. The core of the research is the Lincoln Trade and Environment model (LTEM), a partial equilibrium model which links trade in NZ with the main trading countries overseas, through to production and associated environmental consequences . This paper reports on research expanding the model to include forestry from incorporating the capabilities of the Global Forest Products Model (GFPM) into the LTEM and hence producing an integrated model of agricultural and forestry land-uses for NZ and overseas. The paper extends the environmental modelling capabilities of...

Neoclassical consumer theory and genetically modified food AgEcon
Kaye-Blake, William.
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 food is GM or not, violating attribute independence. Some consumers may not want GM food at all, violating continuity. The axioms were empirically investigated with a choice experiment survey. The paper discusses evidence of violations of both independence and continuity, as well as a non-neoclassical approach to modelling consumer choice.

Process versus product: which determines consumer demand for genetically modified apples? AgEcon
Kaye-Blake, William; Bicknell, Kathryn; Saunders, Caroline M..
One debate in the literature regarding consumers’ reactions to genetically modified food (GMF) centres on whether consumers react to the process of gene technology or to the specific GMF products. Results from a choice experiment survey in New Zealand indicate that consumers are heterogeneous with regard to GMF and that some modifications are viewed more positively than others. These findings suggest that for some consumers the process of gene technology is the decisive factor in evaluatingGMF, while for others the different potential GMF products are valued according to their enhanced attributes.
