AN ANALYSIS OF MARKET STRUCTURE AND PRICING IN THE FLORIDA CELERY INDUSTRY

The pricing behavior of the Florida celery industry under the current federal marketing order was examined by analyzing the implied market structure of the industry using a model proposed by Appelbaum. Point estimates of the oligopoly power index suggest that some degree of price enhancement above that which would be characterized by a perfectly competitive market may have occurred. However, the bulk of statistical evidence suggests that the departure from marginal cost pricing implied by the industry's pricing behavior is not statistically significant.Demand and Price Analysis,

Time Variable Faraday Rotation Measures of 3C-273 and 3C-279

Multifrequency polarimetry with the VLBA confirms the previously reported time-varying Faraday rotation measure (RM) in the quasar 3C-279. Variability in the RM and electric vector position angle (EVPA) of the jet component (C4) is seen making it an unreliable absolute EVPA calibrator. 3C-273 is also shown to vary its RM structure on 1.5 year time-scales. Variation in the RM properties of quasars may result from a Faraday screen which changes on time-scales of a few years, or from the motion of jet components which sample spatial variations in the screen. A new component emerging from the core of 3C-279 appears to be starting to sample such a spatial variation. Future monitoring of this component and its RM properties is suggested as a diagnostic of the narrow line region in 3C-279. We also present a new method of EVPA calibration using the VLA Monitoring Program.Comment: Accepted to ApJ Letters. 12 pages, 5 figure

INCORPORATING STOCHASTIC HARVESTS INTO AN ANALYSIS OF PRODUCTION: THE U.S. ATLANTIC AND GULF OF MEXICO PELAGIC LONGLINE FLEET

Vessel operators maximize expected utility indirectly through cost-minimizing production decisions subject to stochastic harvests. Data on the Atlantic longline fleet, available from NMFS logbooks, is used for the empirical analysis. An ex ante multi-input cost function that incorporates expected rather than realized output levels is estimated and results are reported.Resource /Energy Economics and Policy,
