A structural model of the Pacific halibut fishery is developed. Hypothesis tests
are developed within the framework of the "new empirical industry organization" for
the exertion of market power by Pacific halibut processors in both the exvessel market

Heavy biodegraded crude oils have larger numbers of coeluting compounds than non- biodegraded oils, and they are typically not resolved with conventional gas chromatography (GC). This unresolved complex mixture (UCM) has been investigated using comprehensive two- dimensional gas chromatography-time-of-flight mass spectrometry (GCxGC-ToFMS) within a set of biodegraded petroleums derived from...
