While the significant ecosystem damage caused by invasive weeds has been well documented, the economic impacts of specific invasive weed species are poorly understood. Yellow starthistle (Centaurea solstitialis L., hereafter YST) is the most widespread non-crop weed in California, resulting in serious damage to forage on natural range and improved pasture. A survey was administered to California cattle ranchers to investigate YST infestation rates, loss of forage quantity and value, and control or eradication efforts. The results were used to estimate county-wide economic losses for three focus counties, as well as state-wide economic losses, due to YST in California. Total losses of livestock forage value due to YST on private land for the state of... |

Rates of soil erosion in the dryland cropping region of Saskatchewan are investigated under alternative cropping strategies. Chemical fallow is examined as an alternative to tillage fallow for moisture and soil conservation. Conclusions include: (a) flexible cropping increases net discounted returns and substantially reduced soil erosion compared to the predominant crop rotation; (b) chemical fallow is a viable alternative to tillage fallow but only when topsoil already has been eroded substantially; and (c) an increase in the discount rate is soil conserving, since it causes producers to plant more often rather than fallow. |

In the last two decades, softwood lumber trade between Canada and the United States has been characterized by numerous trade restrictions. Many studies have attempted to quantify the effects of such sanctions, and in doing so, softwood lumber was modeled as a single, homogenous commodity. However, recent research has suggested that this may be a misleading assumption, since not all softwood lumber products are equivalent substitutes. We refer to this problem as the substitution bias, and uniquely address this issue in estimating the effects of trade restricting policies. Using a spatial price equilibrium (spe) model, impacts of the post-sla import duties are estimated and compared to estimates of two alternative policy regimes – an export tax and quota. By... |

Prominent trade disputes between Canada and the U.S. involve agriculture and forestry, with lack of transparency caused by Canadian non-market institutions a source of U.S. objections. Though there has been a recent flurry of activity in the binational dispute resolution panel on Canadian exports of wheat, one of every six panels since 1989 has involved softwood lumber. We examine lessons from the lumber dispute to shed light on U.S. objections to the Canadian Wheat Board (CWB). We argue that U.S. lumber lobbyists will continue to use perceived Canadian institutional obscurity to keep pressure on policymakers, while the CWB system enables similar agricultural interests in to agitate for trade sanctions. Traditional strategies such as dispute resolution... |

A method is suggested for modeling uncertainty when there is a lack of information concerning the effect of forest management decisions on tree growth. Dynamic programming is used to investigate the optimality of alternative management strategies. The model is illustrated with an empirical example for a boreal forest region of western Canada. Three tentative conclusions follow: (a) silvicultural strategies to reduce uncertainty or to increase stand growth may not be worth pursuing, at least in northern forests; (b) the discounted cost of ignoring uncertainty may be substantial if taken over the entire forest; and (c) given uncertain forest growth, flexible harvest policies are preferred to a fixed harvest age. |

Under the U.S. Department of Commerce's 'changed circumstances' review, it is possible that the countervail duty on Canadian lumber can be lowered if administered stumpage prices are based on a transaction evidence appraisal - on actual auction data and regression analysis. The Province of British Columbia is implementing such a market-based approach to set stumpage fees, relying on timber auction data from the Small Business Forest Enterprise Program and OLS regression. We employ Program data to estimate a truncated regression model, comparing our estimates of stumpage fees with the OLS results. It turns out that the OLS approach is biased and likely results in overestimates of stumpage in some timber stands and underestimates in others. Further, we... |

This paper uses Nevada data to conduct regression analyses of the relationship between sage grouse (Centrocercus urophasianus) population sizes and potential causal factors. This is policy-relevant because of current petitions for listing this species under the Endangered Species Act. A key feature is that, although monitoring of sage grouse has occurred for many decades, data collection methods and level of monitoring effort have not been consistent. To account for this feature we use, as dependent variables, standardized measures such as population counts and harvest (hunting success) per unit of effort. Preliminary findings suggest that such measures have been particularly sensitive to whether or not humans used strychnine for predator control, with... |

Current export base methods that calculate basic and non-basic employment are too restrictive because they fail to account for uncertainty involved in the process. This paper shows the assignment of industries as either basic or non-basic by the location quotient procedure does not consistently represent the data for Nevada counties. Using fuzzy set procedures and membership functions in conjunction with the location quotient allow more flexibility in terms of matching the data for each industry in the region of interest. Using fuzzy set procedures we determine the proportion of employment that is basic and non-basic in nine non-governmental industries. |
