A CHOICE-EXPERIMENT BASED ANALYSIS OF PROTECTION MOTIVATION THEORY: HEALTH RELATED BEHAVIOR OF CONSUMERS WITH CELIAC DISEASE AgEcon
Zhang, Jing; Steiner, Bodo E..
The underlying components of protection motivation theory (PMT; Rogers 1983) are explored through choice experiment-based analysis within a random utility framework, to account for some of the motivational, cognitive, and affective processes that likely affect celiacs’ propensity to use a novel health-risk reducing product. Those four groups of variables that are aimed to capture threat appraisal and coping appraisal processes as part of the standard PMT (Rogers 1975, 1983; Floyd et al. 2000) are found to contribute significantly to explaining the adaptive response of celiacs. Self-assessed vulnerability and perceived product efficacy form a most significant part of respondents’ threat appraisal process. Standard socio-demographic and lifestyle...

Accuracy and Asymmetry of Corn, Soybean and Wheat Interval Forecasts AgEcon
Isengildina-Massa, Olga; Sharp, Julia L.; Zhang, Jing; Campbell, Wallace A..
This study evaluates the accuracy of USDA interval forecasts for corn, soybean, and wheat prices using Christoffersen’s (1998) tests for unconditional coverage, independence and conditional coverage adjusted for asymmetries in tail probabilities. The findings of this study demonstrate that due to uneven distribution of forecast misses around the interval, calibration of soybean price forecasts in several cases was rejected by basic coverage tests (suitable for symmetric intervals) but not rejected by the tests adjusted for asymmetry. Thus these forecasts were asymmetric but accurate. Symmetry was not a limiting assumption for corn and wheat interval forecast accuracy.

China Pear Value Chain: Implication for Smallholders AgEcon
Huang, Zuhui; Zhang, Jing; Chen, Kevin Z..
The objective of this paper is to describe different types of value chain, to capture value added activities of each chain, to discuss the organizational and institutional link in each value chain and its implications for the role of small farmers. We focus on two counties in Hebei and Zhejiang of China. Taking pear for example, analysis of value chain is conducted using data of representative samples of pear value chain. For each chain, value added activities, cost composition, profit distribution, organizational and institutional linkages are illustrated, and corresponding conclusions are indicated. After a systematic analysis of organizational and institutional linkage and value adding activities of every chain as well as cost-benefit analysis of...

Food Authenticity, Technology and Consumer Acceptance AgEcon
Hobbs, Jill E.; McDonald, Jillian; Zhang, Jing.
Traceability and authenticity issues have gained increasing prominence in food markets and create both opportunities and challenges for the food industry in providing credible information to consumers. Internal molecular tagging is an emerging technology with the potential to deliver traceability and authenticity assurances. A key question for the food industry in adopting new technologies is consumer acceptance. This paper explores consumer attitudes toward traceability and authenticity and the role of information in affecting consumer acceptance of new technologies, using molecular tagging as an example. Data were gathered from an online survey conducted in Canada in December 2010. To determine whether product-specific effects exist, two versions of the...

Research on the Harmonious Development of New Rural Communities under the Perspective of Balancing Urban and Rural Areas AgEcon
Zhang, Jing.
On the basis of offering a definition of New Rural Communities (NRCs), the paper analyzes the Values of New Rural Communities and argues that the construction of NRCs is able to contribute to the enhancement of the comprehensive agricultural production capability as well as the development of social productivity Meanwhile the incomes of the Rural residents can be boosted, which denotes the realization of a harmonious society where the achievements of China's reform and development are shared by each citizen. Moreover, the construction of NRCs facilitates the economization of land use and thus improves the overall living standard of the residents, while helping to cut the administrative cost and promote democracy at the primary level. This paper also points...

Valuing Western Australia’s Recreational Fisheries AgEcon
Zhang, Jing; Hertzler, Greg; Burton, Michael P..
Australia by using the data from the newly finished National Survey of Recreational Fishing (2000/2001)(NSRF). There are a number of findings. 1. Socio-economic characteristics of anglers didn’t affect their catch of high quality fish (prize fish, reef fish or key-sport fish) as much as their catch of low quality fish (table fish and butter fish). 2. For a given trip, anglers were willing to pay $1.63, $26.03, $1.03 and $0.53 for the first prize fish, reef fish, key-sport fish or butter fish caught, respectively. 3. The top four valuable fishing sites in the survey period were Geraldton, Esperance, Albany and Broome, with annual access values of $6.45 million, $4.52 million, $3.47 million and $2.47 million, respectively. 4. The per trip estimates are of...
