Influence Of Source Credibility On Consumer Acceptance Of Genetically Modified Foods In China, Mingyang Zhang, Chao Chen, Wuyang Hu, Lijun Chen, Jintao Zhan Sep 2016

Influence Of Source Credibility On Consumer Acceptance Of Genetically Modified Foods In China, Mingyang Zhang, Chao Chen, Wuyang Hu, Lijun Chen, Jintao Zhan

Agricultural Economics Faculty Publications

This paper examines the reasoning mechanism behind the consumer acceptance of genetically modified foods (GMFs) in China, and investigates influence of source credibility on consumer acceptance of GMFs. Based on the original Persuasion Model—which was developed by Carl Hovland, an American psychologist and pioneer in the study of communication and its effect on attitudes and beliefs—we conducted a survey using multistage sampling from 1167 urban residents, which were proportionally selected from six cities in three economic regions (south, central, and north) in the Jiangsu province through face to face interviews. Mixed-process regression that could correct endogeneity and ordered probit model …


Market Integration And Price Transmission In The World Rice Export Markets, Bo Chen, Sayed H. Saghaian Sep 2016

Market Integration And Price Transmission In The World Rice Export Markets, Bo Chen, Sayed H. Saghaian

Agricultural Economics Faculty Publications

This paper investigates market integration and asymmetric price transmission in the world rice export markets. Using monthly rice prices from Thailand, Vietnam, and United States, we employ the Johansen test and estimate the threshold vector error correction model (TVECM). Our main findings are that export prices in the three countries are cointegrated, with Thailand and the United States the price leaders, and that the Vietnamese price adjusts faster to long-run equilibrium when it is above its equilibrium level with Thai and U.S. prices. These results suggest market integration and competition rather than collusion are prevalent in world rice markets. Policy …


Are Consumers Willing To Pay More For Sustainable Products? A Study Of Eco-Labeled Tuna Steak, Guzhen Zhou, Wuyang Hu, Wenchao Huang May 2016

Are Consumers Willing To Pay More For Sustainable Products? A Study Of Eco-Labeled Tuna Steak, Guzhen Zhou, Wuyang Hu, Wenchao Huang

Agricultural Economics Faculty Publications

A high demand for seafood leads to overfishing, harms the long-term health of seafood stocks, and threatens environmental sustainability in oceans. Sustainability certification is one of the major sustainability movements and is known as eco-labeling. For instance, in the tuna industry, leading tuna brands have committed to protecting sea turtles by allowing the tracing of the source of their tuna “from catch to can.” This paper relies on an Internet survey on consumers from Kentucky conducted in July 2010. The survey investigates household-level tuna steak (sashimi grade) consumption and examines consumer preferences for eco-labeling (“Certified Turtle Safe” (CTS) in this …


Demand For Pork And Meat In China, Hao Dong Jan 2016

Demand For Pork And Meat In China, Hao Dong

Theses and Dissertations--Agricultural Economics

As the per capita disposable income increases, the demand for meat is boosting in China. Pork, accounting for the largest part of Chinese meat consumption, plays an important role in meat demand in China. This study use data collected from a 2014 survey on Chinese meat consumption; four widely different Chinese cities, Beijing, Changsha, Tianjin and Wuhan are selected to provide a more complete view of Chinese pork and meat demand. We use both OLS model and Tobit model to analyze the effects of consumers' socio-demographic characteristics such as age, gender, income, and education on pork and meat demand. Results …


Values For Recreational Beach Quality In Oahu, Hawaii, Jerrod M. Penn, Wuyang Hu, Linda Cox, Lara Kozloff Jan 2016

Values For Recreational Beach Quality In Oahu, Hawaii, Jerrod M. Penn, Wuyang Hu, Linda Cox, Lara Kozloff

Agricultural Economics Faculty Publications

Pristine coastal environments are the key to Hawaii’s worldwide fame and attraction to tourists, yet their economic value remains understudied. This article examines preferences for characteristics associated with beach recreation in Oahu, Hawaii, among residents and tourists. Consideration is given to sand quality, water quality, congestion levels, and swimming safety conditions in the context of a choice experiment. The choice experiment conveys attribute levels almost entirely through pictures, and results suggest that this novel portrayal is well understood by respondents. Excessive congestion and water quality are regarded as the most important beach attributes, specifically the avoidance of poor water quality …


Determining The Value Of Birthrank And Parent Age In Thoroughbred Racehorses, Xiurui Cui Jan 2016

Determining The Value Of Birthrank And Parent Age In Thoroughbred Racehorses, Xiurui Cui

Theses and Dissertations--Agricultural Economics

Thoroughbred racing is referred to as “the sport of Kings”, because historically it was a leisure activity of the upper-class. Thoroughbred breeding on the other hand has transformed from a hobby of the upper-class to a worldwide agricultural industry. With the deep involvement of the royal and rich in the Thoroughbred industry, the auction prices of horses are raised significantly at the top end of the market.

Research in the biological sciences suggests there exits correlations between dam age, foal birthrank, and the racing performance of Thoroughbred horses. This study first investigates how the market values these biological factors and …

Characteristics Of United States Seafood Consumers, Suliman Almojel Jan 2016

Characteristics Of United States Seafood Consumers, Suliman Almojel

Theses and Dissertations--Agricultural Economics

In this thesis, I conducted an analysis of the consumption patterns associated with demographic and socio-economic characteristics, using Tobit and double-hurdle models. Data were collected for 11,574 households from the US Bureau of Labor Statistics for the year of 2014. Specific determinants included household size, age, income, gender, education, race, region, marital status, and whether the household lived in a coastal state. The results reveal that seafood expenditures are sequential decisions. Asian racial groups, households headed by married couples, a large number of members in households, higher income households, and households residing in the Atlantic and Gulf Coasts were variables …


Economic Considerations Of Aggressively Treating The Influenza Virus In Equines, Charlotte R. Hansen Jan 2016

Economic Considerations Of Aggressively Treating The Influenza Virus In Equines, Charlotte R. Hansen

Theses and Dissertations--Agricultural Economics

The equine influenza virus is a significant cause of respiratory disease in horses. Even though horses generally recover from this virus, sometimes horses with equine influenza develop secondary bacterial infections which can cause severe pneumonia, thereby increasing recovery times. Owners and managers are faced with the decision of whether to delay preventative treatment in hopes of the horse avoids contracting a secondary bacterial infection (“wait and see”) or aggressively treat the horse with an antibiotic in hopes of avoiding a serious infection (“treat now”). From a decision making standpoint, the economic considerations include explicit treatment costs as well as nonmonetary …


Understanding The Molecular Mechanisms Underlying Rsv1 Mediated Resistance To Smv In Soybean, Mohammed Ali Ahmed Eid Jan 2016

Understanding The Molecular Mechanisms Underlying Rsv1 Mediated Resistance To Smv In Soybean, Mohammed Ali Ahmed Eid

Theses and Dissertations--Plant Pathology

Like humans, viral diseases also affect plants. Of these, viruses belonging to the potyvirus genus are the most prolific. The potyvirus soybean mosaic virus (SMV) is an important pathogen of the crop plant soybean. SMV causes mosaic symptoms (yellow areas alternate with dark green areas on the leaves of the plant) and can affect yield by reducing seed quality. Few cultivars from soybean can resist different SMV strains. To understand soybean defense mechanisms to SMV, I identified soybean proteins that interact with the helper component protease (HC-Pro) of SMV, which also functions as the suppressor of host RNA silencing and …
