We use the voluntary adoption of the NuVal shelf nutrition labels by a grocery retailer to estimate the value of these labels to shoppers in the yogurt category. Using an incomplete quadratic almost ideal demand system to represent consumer demand, we found a statistically significant positive effect of these shelf labels on demand for yogurt with above-average NuVal scores. The coefficients on...

The objective of the study was to measure welfare impacts of food price changes on Iranian urban households between two survey data of 2009/10 and 2011/12 which were taken from I...

This paper presents a version of the proportionally calibrated almost ideal demand system (PCAIDS) model, useful for merger simulations, which can be econometrically estimated using price data for two firms in a market. The model is then applied to a database of the Argentine gasoline market, and its results are compared to the ones obtained with other alternative specifications. JEL Classifica...

BACKGROUND Chile is the second world's largest per capita consumer of caloric beverages. Caloric beverages are associated with overweight, obesity and other chronic diseases. The objective of this study is to estimate the price elasticity of demand for soft drinks, other sugar-sweetened beverages and high-energy dense foods in urban areas in Chile in order to evaluate the potential response of ...

Present study investigates the effect of soaring residential electricity price on the welfare of rural individuals in Guilan Province by Almost Ideal Demand System (AIDS) in which the elasticity’s and welfare variations were calculated by Compensation Variations (CV) and Equivalent Variations (EV) for the time period of 1991-2012. It was shown that the absolute value of income and price elastic...

This paper presents estimates of the economic and demographic effects on the demand for steak, roast, and ground beef. Using an almost ideal demand system, the results indicate that demand is inelastic for steak and ground beef, elastic for roast, cross-price effects are significant, and all goods are Hicks-Allen substitutes. The impact of certain demographic effects, such as household size, re...
