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,

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,

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,

Willingness to Pay for a Potential Insurance Policy: Case Study of Trout Aquaculture

Using trout producer survey data and the contingent valuation method, we estimate willing-ness to pay for a potential insurance policy. The survey was conducted in 2005 across the United States; 268 producers completed the survey instrument, resulting in a response rate of 81 percent. Design of the contingent valuation method takes into account two coverage levels and four premium rates. Using standard willingness-to-pay techniques, we assess the premium rate that producers with varying practices and regions are willing to pay for two different cov-erage levels of insurance. In general, trout producers appear willing to pay premium rates of 2 to 11 percent for these coverage levels.willingness to pay, subjective elicitation and survey data, aquaculture trout insurance, Livestock Production/Industries, Risk and Uncertainty,

Challenges Experienced by Aquaponic Hobbyists, Producers, and Educators

We used an online survey to document challenges experienced by aquaponic hobbyists (n = 81), producers (n = 117), and educators (n = 75). Responses were distilled into the following categories: 1) operations and management; 2) facilities, location, and system design; 3) knowledge and educational resources; 4) funding; 5) economic viability; 6) plant culture; 7) marketing and distribution; 8) fish culture; 9) human factors; 10) regulations and certifications. Training and research in these areas are needed to advance the aquaponics industry

Search for a vector-like quark T′ → tH via the diphoton decay mode of the Higgs boson in proton-proton collisions at s \sqrt{s} = 13 TeV

A search for the electroweak production of a vector-like quark T′, decaying to a top quark and a Higgs boson is presented. The search is based on a sample of proton-proton collision events recorded at the LHC at = 13 TeV, corresponding to an integrated luminosity of 138 fb−1. This is the first T′ search that exploits the Higgs boson decay to a pair of photons. For narrow isospin singlet T′ states with masses up to 1.1 TeV, the excellent diphoton invariant mass resolution of 1–2% results in an increased sensitivity compared to previous searches based on the same production mechanism. The electroweak production of a T′ quark with mass up to 960 GeV is excluded at 95% confidence level, assuming a coupling strength κT = 0.25 and a relative decay width Γ/MT′ < 5%
