Food Safety and Demand: Consumer Preferences for Imported Pork in Urban China
China’s transition into a developed economy is driving changes in consumer preferences and demand for foods. The objective of this study is to assess and measure consumers’ preferences for and attitudes toward imported pork in urban China. Estimated logit models based on a consumer survey conducted in 2008 reveal that individuals’ age, shopping location, and food safety concerns significantly influence their willingness to pay for U.S. pork. Factors affecting purchasing behavior of Western-style pork cuts versus traditional Chinese cuts are also evaluated. Consumers’ food safety concerns were linked to a previous lean-meat additive scare and a lack of confidence in the Chinese food inspection system.Consumer/Household Economics, Food Consumption/Nutrition/Food Safety, Livestock Production/Industries,
Consumer Preferences for U.S. Pork in Urban China
China’s transition into a developed economy is driving changes in consumer preferences and demand for foods. To evaluate consumer preferences for U.S. pork in urban China, primary data were collected in two metropolitan areas- Beijing and Shanghai. Estimated logit models revealed that an individual’s age, shopping location and food safety concerns significantly influenced their willingness-to-pay for U.S. pork. A proportional linear model was developed to evaluate factors affecting purchasing behavior of western-style pork cuts vs. traditional Chinese cuts. Food safety concerns were linked to a previous lean-meat additive scare and a lack of consumer confidence on the Chinese food inspection system.China, U.S. Pork, Willingness-to-pay, Ordered Logit, food safety, Agricultural and Food Policy, Consumer/Household Economics, Marketing, D120, D190, M390, Q130, Q180,
Relative periodic orbits in point vortex systems
We give a method to determine relative periodic orbits in point vortex
systems: it consists mainly into perform a symplectic reduction on a fixed
point submanifold in order to obtain a two-dimensional reduced phase space. The
method is applied to point vortices systems on a sphere and on the plane, but
works for other surfaces with isotropy (cylinder, ellipsoid, ...). The method
permits also to determine some relative equilibria and heteroclinic cycles
connecting these relative equilibria.Comment: 27 pages, 17 figure
