Study of Evacuation Behavior of Coastal Gulf of Mexico Residents

In this study, we investigate the link between hurricane characteristics, demographics of the Coastal Gulf of Mexico residents, including their household location, and their respective evacuation behavior. Our study is significantly different from the previously made studies on hurricane evacuation behavior in two ways. At first, the research data is collected through recording responses to a series of hypothetical situations which are quite identical to the set of information that people are used to see during the hurricane season. Secondly, this study addresses and includes response heterogeneity while analyzing sample behavior, an issue which has not been addressed in previous research on hurricane evacuation behavior in spite of its importance.Evacuation Behavior, Hurricane, Response Heterogeneity, Environmental Economics and Policy, Research Methods/ Statistical Methods, Risk and Uncertainty, C35, Q54,

Price Volatility Spillover in Agricultural Markets: An Examination of U.S. Catfish Markets

Price volatility spillovers in the U.S. catfish supply chain are analyzed based on monthly price data from 1980 through 2000 for catfish feed, its ingredients, and farm- and wholesale-level catfish. The exponential generalized autoregressive conditional heteroskedasticity (EGARCH) model was used to test univariate volatility spillovers for prices in the supply chain. Strong price volatility spillover from feeding material (corn, soybeans, menhaden) to catfish feed and farm- and wholesale-level catfish prices was detected.catfish, EGARCH, vertical market chains, volatility spillover, Demand and Price Analysis,

A Comparison Of Choice Experiments And Actual Grocery Store Behavior: An Empirical Application To Seafood Products

In this paper we compare results from an in-store field experiment and a mail survey choice experiment (CE) to investigate CE’s capacity in predicting grocery store market share. For the comparison, we used three seafood products: freshwater prawns, marine shrimp, and lobster. CE estimates were obtained via four econometric models: the conditional logit, the random parameter logit, the heteroskedastic extreme value, and the multinomial probit. We found that the level of control in the grocery store experiment and the choice of econometric model influenced the capacity of CE to predict grocery store market shares.choice experiment, grocery store, hypothetical bias, Food Consumption/Nutrition/Food Safety, Marketing, C35, Q13,

COASTAL ALABAMA RECREATIONAL LIVE BAIT STUDY

Recreational fishing is major industry and reasonably priced, high quality bait plays an important role in sustaining recreational fishing's popularity. This study provides a summary of Alabama's coastal live bait market including information on previous live bait studies and results of two surveys on the live bait shrimp, bull minnow and other bait markets. Results indicated there were periods of supply shortages, dealer willingness to pay more for shrimp that live longer and a dealers' use of multiple supply sources. Lost income was reported from not having live bait shrimp available for sale at peak demand periods. The economics of shrimp mariculture needs to be examined to determine its feasibility in augmenting the current supply of shrimp to the live bait industry.Resource /Energy Economics and Policy,

Comparison of Stated Choice and In-store Experimental Methods in Predicting Actual Market Behavior for Freshwater Prawn (Macrobrachium rosenbergii) Consumers

The stated choice (SC) and actual revealed pricing/purchase experimental methods were compared for their ability to predict purchasing behavior and willingness-to-pay for freshwater prawns. SC hypothetical bias may be a consequence of difficulties in controlling factors affecting real world situations, small sample sizes and confusion related to the new product.choice experiment, grocery store experiment, new product, purchasing behavior, Consumer/Household Economics,

AT-HOME AND AWAY-FROM-HOME CONSUMPTION OF SEAFOOD IN THE UNITED STATES

At-home consumption of shrimp, oysters, and catfish is investigated, using data from a mail survey conducted in 2000-2001. Results indicated consumers probability and frequency of consumption decreased if consumers felt they lacked preparation knowledge, product preparation was too time consuming, or the smell was unattractive. Demographics were also significant.Consumer/Household Economics,

Asymptotic solutions for the asymmetric flow in a channel with porous retractable walls under a transverse magnetic field

The self-similarity solutions of the Navier-Stokes equations are constructed for an incompressible laminar flow through a uniformly porous channel with retractable walls under a transverse magnetic field. The flow is driven by the expanding or contracting walls with different permeability. The velocities of the asymmetric flow at the upper and lower walls are different in not only the magnitude but also the direction. The asymptotic solutions are well constructed with the method of boundary layer correction in two cases with large Reynolds numbers, i.e., both walls of the channel are with suction, and one of the walls is with injection while the other one is with suction. For small Reynolds number cases, the double perturbation method is used to construct the asymptotic solution. All the asymptotic results are finally verified by numerical results.</p
