U.S. Demand for Source–Differentiated Shrimp: A Differential Approach AgEcon
Jones, Keithly G.; Harvey, David J.; Hahn, William F.; Muhammad, Andrew.
Estimates of price and scale elasticities for U.S. consumed shrimp are derived using aggregate shrimp data differentiated by source country. Own-price elasticities for all countries had the expected negative signs, were statistically significant, and inelastic. The scale elasticities for all countries were positive and statistically significant at the 1% level with only the United States and Ecuador having scale elasticities of less than one. For the most part, the compensated demand effects showed that most of the cross-price effects were positive. Our results also suggest that despite the countervailing duties imposed by the United States, shrimp demand was fairly stable.

NUTRIENT EFFECTS ON CONSUMER DEMAND: A PANEL DATA APPROACH AgEcon
Dhehibi, Boubaker; Gil, Jose Maria; Angulo, Ana Maria.
The objective of this paper is to analyze the Spanish demand for food taking into account the consumer's concern about the relationship between food diet and health. This concern is forcing food demand analysts to assume that consumer utility is a function of nutrients instead of simply the food products themselves. A CBS demand model has been considered to model the new demand function obtained, which is estimated with a complete panel data set. Ten broad categories, nine nutrients and the most relevant socio-economic variables have been considered. Finally, after an appropriate model selection strategy, expenditure, price and nutrient elasticities, as well as main sociodemographic effects, have been calculated.
Tipo: Conference Paper or Presentation Palavras-chave: Nutrients; Demand for food; CBS; Panel data; Spain.; Demand and Price Analysis; Food Consumption/Nutrition/Food Safety.
