“A Definition at Last, But What Does it All Mean?” Newspaper Coverage of Organic Food Production and its Effects on Milk Purchases AgEcon
Kiesel, Kristin.
This paper estimates the effects of media coverage of organic food production on food purchases. Information from several data sources links national and local newspaper coverage to fluid milk purchases. An analysis of weekly store-level scanner data in a differences-in-differences approach results in a 5% increase in organic milk sales relative to conventional milk sales. Increases in intensity of news coverage increase this relative difference in sales. Differentiating effects by media context further suggests that product category specific coverage increases sales more than general coverage. Critical coverage does not result in significant effects on organic milk sales.

Advertising and Product Confusion: A Case Study of Grapefruit Juice AgEcon
Brown, Mark G.; Lee, Jonq-Ying; Behr, Robert M..
Demand relationships for two closely related products -- grapefruit juice and grapefruit-juice cocktail -- were estimated from grocery-store scanner data to analyze the contention that consumer confusion exists between the two products. Results suggest confusion may exist, with grapefruit-juice advertising not only increasing the demand for grapefruit juice but also for grapefruit-juice cocktail.

Buyer and Seller Response to an Adverse Food Safety Event: The Case of Frozen Salmon in Alberta AgEcon
Maynard, Leigh J.; Saghaian, Sayed H.; Nickoloff, Megan.
Fish is a low-fat protein source high in omega-3 fatty acids, but in 2004 consumers also heard that farmed salmon had high levels of polychlorinated biphenyl (PCBs). This research evaluated how Canadian consumers and processors reacted to the conflicting health messages. Demand estimates and time-series analysis of 2001-2006 frozen meat scanner data in Alberta, Canada show a significant drop in salmon expenditure share following the PCB finding. The industry responded by launching low-priced wild salmon products, which contributed to significant demand expansion. The analysis illustrates how a food safety threat was averted and even served as a catalyst for growth.

Can Information Costs Affect Consumer Choice?—Nutritional Labels in a Supermarket Experiment— AgEcon
Kiesel, Kristin; Villas-Boas, Sofia Berto.
This paper investigates whether information costs under currently regulated nutritional labeling prevent consumers from making healthier food choices. We implement five nutritional shelf label treatments in a market-level experiment. These labels reduce information costs by highlighting and summarizing information available on the Nutritional Facts Panel. Following a difference-in-differences and synthetic control method approach, we analyze weekly store-level scanner data for microwave popcorn purchases from treatment and control stores. Our results suggest that consumer purchases are affected by information costs. Implemented low calorie and no trans fat labels increase sales. In contrast, implemented low fat labels decrease sales, suggesting that...

Comparing Two Sources of Retail Meat Price Data AgEcon
Hahn, William F.; Perry, Janet E.; Southard, Leland W..
The livestock industry uses information on meat prices at different stages in the marketing system to make production decisions. When grocery stores began using electronic scanners to capture prices paid for meat, it was assumed that the livestock industry could capitalize on having these point-of-sale data available as a measure of the value of its products. This report compares scanner price data with publicly available data collected by the U.S. Department of Labor’s Bureau of Labor Statistics (BLS). Of the two data types, scanner data provide more information about retail meat markets, including a wider variety of meat-cut prices, multiple measures of an average price, the volume of sales, and the relative importance of discounted prices. The scanner...

Consumer and Market Responses to Mad-Cow Disease AgEcon
Schlenker, Wolfram; Villas-Boas, Sofia Berto.
We examine how consumers and financial markets in the United States react to two health warnings about mad cow disease: The first discovery of an infected cow in December 2003 as well as health warnings about the potential effects aired in the highly-watched Oprah- Winfrey show seven years earlier. Using a unique UPC-level scanner data set, we find a pronounced and significant reduction in beef sales following the first discovered infection. This effect slowly dissipates over the next three months. Interestingly, no significant impact can be detected in the diary files of the Consumer Expenditure Survey (CES) that has a much smaller sampling frame. However, futures prices show a comparable drop in prices to the scanner data. Contracts with longer maturity...

Consumer Choices and Welfare Gains from New, Healthy Products: A Virtual Price Approach AgEcon
Huffman, Sonya Kostova; Ishdorj, Ariun; Jensen, Helen H..
This paper models consumer food choices with respect to different margarine and spread brands that include a new healthy brand. The results show that the older and smaller size households with higher income and higher education are more likely to purchase the healthy brand. An Almost Ideal Demand System for six brands was estimated and the coefficients were used to calculate price and brand expenditure elasticities in order to examine the responsiveness of the consumers to economic variables.

DEMAND FOR ENHANCED FOODS AND THE VALUE OF NUTRITIONAL ENHANCEMENTS OF FOOD: THE CASE OF MARGARINES AgEcon
Huffman, Sonya Kostova; Jensen, Helen H..
This paper evaluates consumer preferences and choice of nutritionally enhanced food products based on economic, geographic, ethnic and other socioeconomic characteristics. Household scanner data allow estimation of hedonic price function and a probit model on the choice of margarine that promotes good health. The empirical estimation established a positive value for nutritional enhancement.

Does Limited Access at School Result in Compensation at Home? The Effect of Soft Drink Bans in Schools on Purchase Patterns Outside of Schools AgEcon
Huang, Rui; Kristin, Kiesel.
This paper investigates the effects of banning soft drinks in schools on purchases outside of school. We utilize unique household-level and store-level data sources in combination with time-series and cross-sectional variation of state-level regulations in a difference-in-differences (DD) approach. We detect a decrease in the overall trend in sales, but observe this downward trend in households with and without children, as well as in states with and without regulation. Controlling for advertising allows us to further reject that leading brands intensify their advertising efforts and target children to potentially offset their reduced presence at schools. Finally, we find no evidence of substitution effects among possible beverage product alternatives. Our...

EMPIRICAL TESTS OF THE ARGUMENT THAT CONSUMERS VALUE STABLE RETAIL MILK PRICES AgEcon
Maynard, Leigh J..
Existing policy allows interstate dairy compacts if they serve a compelling public interest. Compact supporters argue consumers benefit from retail price stability, but no supporting evidence was found. Milk demand systems were estimated using scanner data and four measures of price volatility. Price volatility defined as forecast errors influenced demand, but did not systematically depress demand. Response was more elastic to unanticipated than anticipated price changes, possibly explaining the higher elasticities often observed in scanner data studies.

FRAGILITY IN DAIRY PRODUCT DEMAND ANALYSIS AgEcon
Maynard, Leigh J.; Liu, Deyu.
Several reasons justify the expectation of increasingly price elastic demand for dairy products. Using weekly scanner data, we find support for this hypotheses, but with wide variation in elasticity estimates across model specifications. The results demonstrate the need for more routine specification testing before basing recommendations on potentially fragile inferences.

Neue empirische Befunde zur Preissetzung und zum Verbraucherverhalten im Lebensmitteleinzelhandel AgEcon
Herrmann, Roland; Moser, Anke; Werner, Elke.
There are two objectives of this article: (i) It is discussed theoretically how the dynamics of pricing decisions of multiproduct retailers can be explained. (ii) It is analyzed empirically by use of scanner data how prices are actually set and how consumers react at the point of sale to price changes and promotional activities by retailers. The empirical evidence focuses on breakfast products in general and jam and breakfast cereals in particular. Main results are the following: 1. Theory of optimal pricing by multiproduct firms suggests that direct and cross price elasticities of demand and marginal costs determine the profit-maximizing price at one point of time. Good reasons do exist additionally for multiproduct retailers to vary prices...

On the Accuracy of Nielsen Homescan Data AgEcon
Einav, Liran; Leibtag, Ephraim S.; Nevo, Aviv.
Researchers use Nielsen Homescan data, which provide detailed food-purchase information from a panel of U.S. households, to address a variety of important research topics. However, some question the credibility of the data since the data are self-recorded and the recording process is time-consuming. Matching purchase records from 2004 Homescan data with data obtained from a large grocery retailer, it is evident that quantities purchased are reported more accurately in Homescan than are prices. Many of the price differences may be driven by the way Nielsen imputes prices: when available, Nielsen uses store-level prices instead of the actual price paid by the household. There are also differences by household type in the tendency to make mistakes that are...

The Impact of Social Capital on the Implicit Price Paid by the Italian Consumer for Fair Trade Coffee AgEcon
Bosbach, Moritz; Maietta, Ornella Wanda.
Consumers in developed countries are increasingly interested in the consumption of food products incorporating ethical aspects, particularly fair trade products. These products are usually distributed in a network of World Shops and, more recently, in supermarkets and shopping centres. The fair trade product with the highest market share is coffee. This study aims to ascertain the implicit price paid by Italian consumers for the fair trade content of coffee and how this implicit price is influenced by the level of social capital of the territory where consumers live. The data utilised are scanner data, based on the purchase at supermarkets and shopping centres observed from 2005 to 2007, referred to a territorial unit that is the province. Since scanner...

The Value to Consumers of Health Labeling Statements on Breakfast Foods and Cereals AgEcon
Muth, Mary K.; Zhen, Chen; Taylor, Justin; Cates, Sheryl; Kosa, Katherine M.; Zorn, David; Choiniere, Conrad J..
Food manufacturers have an incentive to include nutrient content claims, health claims, or other types of labeling statements on foods if they believe that consumers will be willing to pay more for products with specific attributes. We estimated semi-log hedonic price regressions for five breakfast bar and cereal product categories using Nielsen ScanTrack scanner data for 2004 and found that labeling statements for these foods are often associated with substantial increases in consumer willingness to pay. The largest effects were associated with “carb-conscious” carbohydrate labeling (reflecting the time period of the data), followed by fat and sugar content labeling statements.
