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... |

Climate change is a subject of global environmental concern. The UK has seen a progressive strengthening of political resolve to address the problems associated with emissions of greenhouse gases (GHGs), principally carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). Although agriculture globally, and ruminant livestock production in particular, is a net contributor to GHG emissions, generalizations about impacts on climate change often fail to distinguish between different systems of production, advances in technology, and the role of extensive grazing lands in contributing to ecological services and food production in situations where other forms of farming are impractical. Against this background, the overall aim of this review was therefore to... |

Given that approximately half of all U.S. farmland is leased, absentee (non-operator) landowners have a significant role in agriculture. Because decisions about how to use farmland can be affected by ownership status, tenure can have far reaching implications for the production of food and fiber, as well as the extent to which environmentally sensitive farmland is cropped or is put into a conservation use. In order to better understand whether conservation participation decisions, and potential responses to factors such as commodity prices, may vary by tenure status, we exploit a unique dataset that identifies where participants associated with Conservation Reserve Program contracts live relative to the land enrolled. These data provide improved spatial... |

This paper provides an empirical analysis of the role of intergovernmental relations on a country's effort to enforce the objectives of an international environmental agreement on an open access resource. Intergovernmental interaction allows signatory countries to observe compliance behavior of other signees and to punish non-compliance by applying bi- and multilateral sanctions. We use a cross-sectional dataset that contains country level information about compliance with Article 7 of the 1995 UN Code of Conduct for Responsible Fisheries. Our identification strategy combines a spatial autoregressive model with spatial autoregressive disturbances and an instrumental variable approach. We find a strong positive effect of other countries' compliance on the... |

This paper examines the impact of dolphin-safe eco-labeling and how it fundamentally altered the spatial distribution of fishing effort and fishermen's willingness to pay to avoid dolphins. To do this, a dynamic discrete choice econometric model is applied to the Eastern Tropical Pacific tuna fishery. This econometric approach combines a dynamic programming component with the static discrete site choice model. This estimator couples the current period projected profits associated with fishing a specific site with the value of all future location choices on the cruise, assuming choices are made optimally. The key feature of this model is that it recovers behavioral parameters and solves the dynamic programming problem recursively. The dynamic site... |

The objective of this paper is to investigate the usefulness of non-cooperative bargaining theory for the analysis of negotiations on water allocation and management. We explore the impacts of different economic incentives, a stochastic environment and varying individual preferences on players strategies and equilibrium outcomes through numerical simulations of a multilateral, multiple issues, non-cooperative bargaining model of water allocation in the Piave River Basin, in the North East of Italy. Players negotiate in an alternating-offer manner over the sharing of water resources (quantity and quality). Exogenous uncertainty over the size of the negotiated amount of water is introduced to capture the fact that water availability is not known with... |

The non-point pollution rules proposed by the Wisconsin Department of Natural Resources (DNR) have generated questions regarding the costs of compliance for Wisconsin agriculture. It is clear that some agricultural practices will have to change if the proposed rules are enacted, but the costs of these changes are less clear. The DNR proposals include cost sharing for the introduction of best management practices, but constrain the cost share program to essentially out of-pocket expenses. In general, there is no compensation for costs associated with additional management time, or lost revenue. The purpose of this project is to generate a set of estimates relating to net costs of compliance for Wisconsin crop producers. The intent is to develop a baseline... |
