The rhenium-osmium isotopic system has the potential to track the maturation of arc crust at lower crustal levels because the ¹⁸⁷Os/¹⁸⁸Os in magmas is sensitive to the age and composition of crust with which they interact. We here present Re and Os isotopic data for a suite of samples from...
Some consideration has been given to the irrigation of winter
wheat in the Willamette Valley of Oregon. This important crop has
yielded quite well since the development and introduction of the
stiff-strawed, semi-dwarf wheats, but, because of the usually dry
early summers, it has been suggested that irrigation of winter...
Quota, a computer-based simulation game, originated as an experimental game for testing alternative multi-resource management regimes or systems. Highly flexible, it allows specification for a standard common-property, open-access fishery with user-specified bio-economic fishery growth model and multiple sized producers with individual harvest and cost functions. In addition to demonstrating overfishing...
There is growing realization of the potential for games and experiments as powerful tools not only for research, but also for education and outreach. Experiments are particularly powerful and useful for fisheries economists because (a) they can vividly illustrate some fundamental concepts and (b) are effective at testing the relative...
The paper reports on a large-scale demand model for recreational fishing in Michigan. The model is based on the travel cost method and is specified as a four-level nested-logit. Seasonal participation is modeled by repeating the site choice logit over the course of a season. Data on anglers' trips and...
