This report describes an integrated agro-ecological modeling system that was developed to assess the potential economic and soil erosion impacts of different agricultural policies for the Canadian prairie provinces of Alberta, Saskatchewan, and Manitoba. The system was constructed by linking erosion metamodels (response functions), based on multiple simulations of the USDA Erosion Productivity Impact Calculator (EPIIC), with a modified version of Agriculture Canada's Canadian Regional Agriculture Model (CRAM) denoted as RS-CRAM (resource sensitive CRAM). A summary of both the environmental and agricultural decision (RS-CRAM) components are presented, including a description of the modifications and enhancements that were made to CRAM. Results of policy... |

The interface between RS-CRAM and the environmental component of the integrated modeling system is described for crops, crop sequences, and management systems representative of western Canada. An experimentally designed set of EPIC simulations were performed to generate erosion output that was used to construct wind and water erosion metamodels (response functions). The results of the EPIC simulations indicate that wind and water erosion would be the dominant erosion problem over most of Saskatchewan and Manitoba. For Alberta, water erosion was predicted to be the dominant problem, except for the southern portion of the province. Erosion impacts were sensitive to tillage and cropping patterns. EPIC-predicted yields did not vary much across tillage, a... |

Ivory poachers threaten the half million remaining African elephants. In response, Kremer and Morcom (2000) offer a novel solution to reduce the risk of extinction -- a local government can stockpile ivory and threaten to dump it on the market if the elephant population falls too low lowering the expected returns from ivory sales and driving poachers out of business). We show that ivory stockpiling could be detrimental to elephant conservation because large stocks create strong incentives for strategic extinction by African governments. This result suggests an alternative strategy to enhance the viability of African elephant stocks -- international conservation organizations rather than governments should hold the stockpiles. |

The introduction of counter-cyclical payments (CCPs) and a base acreage updating option under the 2002 Farm Act have potential supply response implications. To gain insight into the economic incentives and efficiency implications of these provisions, this paper presents the design of a 3-stage experimental market used to gauge the actual response of economic agents under conditions simulating those faced by U.S. farmers. When completed, the results of the experiment will be used to assess the impact of the CCP system and of policy uncertainty regarding future base-updating options, relative to a market revenue-only baseline. |

This paper addressed the puzzling resistance of Presidents of southern African countries to food aid in 2002, given near certain starvation and long-term negative health effects of malnutrition of their constituents. First, I show that NGOs led by Greenpeace and Friends of the Earth are disseminating information claiming that GM foods are dangerous to human health and are "Frankenfoods." Second, people in European Union countries, who are not in any danger of starvation, have strong preferences for non-GM foods, which they can easily afford. Over the long term, however, the tastes of EU consumers matter to southern African countries because some of these countries hope to export agricultural products in the future. GM-food aid, which most likely would... |

We propose a novel explanation for the emergence of language in modern humans, and the lack thereof in other hominids. A coevolutionary process, where trade facilitates speech and speech facilitates trade, driven by expectations and potentially influenced by geography, gives rise to multiple stable development trajectories. While the trade-speech equilibrium is not an inevitable outcome for modern humans, we do find that it is a relatively likely result given that our species evolved in Africa under climatic conditions supporting relatively high population densities. |

The beginnings of agriculture, or the agricultural revolution, is now recognized to be the widespread adoption of known practices – a change in behavior – as opposed to a phenomenon of discovery and innovation. In this paper, we combine elements of three theories—climate change, property rights, and competitive exclusion—to create a paleoeconomic model of agriculture and its diffusion. We focus on climate change as a necessary trigger, which combined with group property rights and competitive exclusion processes produced conditions sufficient for the diffusion of early agriculture. In contrast to other models in which farming emerges as technological progress or climate makes it a more productive option than hunting, farming emerges in our model even if... |

With the continuing controversy over genetically modified (GM) foods, some groups advocate mandatory labeling of these products, while other groups oppose labeling. An important issue is how GM labels affect consumers' willingness to pay for these food products in the market. Using a statistically based economics experiment with adult consumers as subjects, we examine how willingness to pay changes for three food products--vegetable oil, tortilla chips, and potatoes--when GM labels are introduced. Participants in the experiments discounted GM-labeled foods by approximately 14% relative to their standard-labeled counterparts. The evidence also showed that sequencing of food labels affects willingness to pay, and that randomizing treatments is an important... |

This paper examines the market characteristics that push consumers in high income countries to resist GM foods, with an emphasis on negative information from environmental groups and third-party, verifiable information. For this study, unique data were collected from adult consumers in the United States who participated in laboratory auctions of three food types with randomly assigned labeling and information treatments. Using U.S. consumers is important because U.S. consumers are generally supportive of GM foods and free from the BSE "food scare" fears and bias towards "natural" that are hypothesized to lead Europeans to reject GM foods. Key findings are that negative GM-product information supplied by environmental groups pushes some consumers out of... |

Economics can make good policy better and bad policy go away- a message often constrained by the political realities surrounding federal resource policy toward the West. This essay responds to these challenges to economic reasoning based on the lessons learned after a stay at the Council of Economic Advisers. My goal is to help make apolitical economists more effective advocates of efficiency. |

Experimental markets can be a useful tool to guide and evaluate environmental policy. This paper reviews four experiments to illustrate. Two institutional experiments are considered-Coasian bargaining with positive transaction costs, and a gaming experiment of dynamic choice in a conflict. Two valuation experiments are also discussed-the impact of sequential reduction mechanisms on the value of risk, and experimental auction markets to elicit the value of safer food. |
