A COST-BASED MODEL OF SEASONAL PRODUCTION, WITH APPLICATION TO MILK POLICY AgEcon
Hennessy, David A.; Roosen, Jutta.
Milk production is seasonal in many European countries. While quantity seasonality poses capacity management problems for dairy processors, a European Union policy goal is to reduce price seasonality. After developing a model of endogenous seasonality, we study the effects of three E.U. policies on production decisions. These are private storage subsidies, production removals, and production quotas. When cost functions are seasonal in a specified way, then arbitrage opportunities interact with storage subsidies to reduce both price and consumption seasonality. But production seasonality likely increases because storage subsidies promote temporal market integration. Conditions are identified under which product market interventions increase quantity...

A HAZARD ANALYSIS OF CONSUMERS’ SWITCHING BEHAVIOUR IN GERMAN FOOD RETAILING FOR DAIRY PRODUCTS AgEcon
Olearius, Gotz; Roosen, Jutta; Drescher, Larissa S..
German food retailing is characterized by fierce competition among retail chains for consumer shopping. This paper considers the switching behaviour using data of white dairy product purchases. The empirical investigation uses a survival analysis approach, in particular hazard analysis. The results extend the knowledge of shopping behaviour by providing a new set of explaining variables and the importance of the first store, defined as store with the major share of household budget, becomes apparent. On average, households buy dairy products 42 times per year. Thereof 58 % are retail chain switches and in 41 % of all cases the households remain at the previously visited retail chain. Generally a low customer loyalty is visible in this investigation. It is...

A REGIONAL ECONOMETRIC MODEL OF U.S. APPLE PRODUCTION AgEcon
Roosen, Jutta.
A four-region econometric model of U.S. apple production and consumption is developed. Technical progress has benefited growers in the Northwest the most, but prices there are much lower in comparison to other regions. Estimated elasticities are used to estimate national and regional welfare impacts of pesticide cancellations.

A REGIONAL ECONOMETRIC MODEL OF U.S. APPLE SUPPLY AND DEMAND AgEcon
Roosen, Jutta.
An econometric model of U.S. apple supply and demand is estimated using annual data for 1971-1997. Supply is arranged into four geographical regions, the Northwest, the Southwest, the Central, and the East. The structural model consists of five components: supply, allocation between fresh and processed utilization, pricing, demand and net imports. Estimated supply elasticities illustrate regional differences in growers' ability to respond to market changes.

AN ANALYSIS OF THE RETIREMENT-CONSUMPTION PUZZLE FOR FOOD-AT-HOME AND AWAY-FROM-HOME EXPENDITURES IN GERMANY AgEcon
Drescher, Larissa S.; Roosen, Jutta.
According to Ando and Modigliani (1957), consumers pass different stages of a lifecycle with different impact on demand. The criticism that the life-cycle theory neglects generational effects and concentrates on ageing effects only has led to the application of the cohort analysis which decomposes not only age, but also period and cohort effects. Following these ideas, this paper presents results of a cohort analysis on food-at-home and away-from-home consumption covering 25 years of German consumption data. Special attention is given to the retirement-consumption puzzle which is the unanticipated drop in consumption after retirement. Results of seemingly unrelated regressions indicate that there are significant age, period and cohort effects of...

AN EQUILIBRIUM ANALYSIS OF ANTIBIOTICS USE AND REPLANTING DECISIONS IN APPLE PRODUCTION AgEcon
Roosen, Jutta; Hennessy, David A..
Antibiotics are used in fruit production to control fire blight, a bacterial disease of fruit trees that causes yield losses and eventually tree death. Fearing the development of widespread antibiotic resistance, scientists and public health officials are becoming increasingly concerned about antibiotics use in agriculture. A framework is developed for assessing the impacts of changes in tree damage risk following a ban on antibiotics use in the apple industry. Allowing for entry and exit, a long-run analysis of replanting dates and equilibrium prices is provided, as well as an estimate of the welfare impacts of a ban on antibiotics.

Can local be the new organic? Food choice motives and willingness to pay AgEcon
Roosen, Jutta; Kottl, Barbara; Hasselbach, Johanna.
Due to growth and changing distribution channels for organic food in Germany, there is some concern that organic food will lose against local food in the competition for conscious consumers. In this paper we will present the results of a survey in Bavaria searching for consumer motives and label recognition. A choice experiment using different prices, brands and labels is conducted for bread, beer and milk. Results show the importance of local production to the surveyed consumers, similarly for conventional as for organic products.

Characteristics of loyal customers for trade chains in the German food retailing AgEcon
Olearius, Gotz; Roosen, Jutta.
In this paper customer loyalty will be examined with the help of budget ratios (budget shares). We address the question whether sociodemographic groups differ in their shopping behavior and their store loyalty. Loyalty is analyzed with regard to the ten largest food retail chains in Germany in 2002. It is shown that the loyalty of customers depends on the lifecycle stage of the household and household size for the most part. Older and single households are more loyal than younger families.

CONSUMER DEMAND FOR AND ATTITUDES TOWARD ALTERNATIVE BEEF LABELING STRATEGIES IN FRANCE, GERMANY, AND THE UK AgEcon
Roosen, Jutta; Lusk, Jayson L.; Fox, John A..
A wide array of food safety scares and breakdowns have led to loss of consumer confidence in the quality and safety of beef products. To counteract such concerns, firms and regulators have the ability to utilize brands or labels to signal quality. Utilizing a mail survey in France, Germany, and the United Kingdom, we analyzed consumer preferences for alternative beef labeling strategies. Using an ordered probit model and a double bounded logit model, we estimate consumer preferences for alternative beef labeling programs. In general, results suggest that consumers have more confidence in government mandated labels as opposed to private brands. French and German consumers place a higher level of importance on brands and labels than do UK consumers....

Consumer preferences for ground beef packaged under a modified atmosphere AgEcon
Grebitus, Carola; Jensen, Helen H.; Sebranek, Joseph G.; Roosen, Jutta; Anders, Sven M..
The main objective of this paper is to identify factors that determine consumers’ purchase decisions for ground beef offered with different packaging technologies. Consumers’ increasing knowledge about food technologies and changes in food labeling regulation influence agribusiness’ future product development and marketing strategies. Non-hypothetical choice experiments with ground beef, conducted in the USA, are used to quantify consumers’ valuation of technology-related attributes namely shelf life, color and packaging. How alternative types of information affect consumers’ WTP is of particular importance to processors and food safety analysts. This paper’s methodological contribution lies in applying advanced methods to elicit consumers' estimates of...

CONSUMERS' VALUATION OF INSECTICIDE USE RESTRICTIONS: AN APPLICATION TO APPLES AgEcon
Roosen, Jutta; Fox, John A.; Hennessy, David A.; Schreiber, Alan.
Economic assessments of pesticide regulations typically focus on producer impacts and generally ignore possible changes in product demand. These changes may be nonnegligible if real and/or perceived product attributes change. We measure consumers’' willingness to pay (WTP) for the elimination of one insecticide and also a whole group of insecticides in apple production using a multiple-round Vickrey auction. The data are analyzed using nonparametric statistical tests and a double-hurdle model. Our findings show that consumer perceptions of product attributes change if pesticides are removed from production, and this is reflected in WTP changes. WTP is shown to be income elastic.

DEMAND FOR BEEF FROM CATTLE ADMINISTERED GROWTH HORMONES OR FED GENETICALLY MODIFIED CORN: A COMPARISON OF CONSUMERS IN FRANCE, GERMANY, THE UNITED KINGDOM, AND THE UNITED STATES AgEcon
Lusk, Jayson L.; Roosen, Jutta; Fox, John A..
This study compares consumer valuations of beef steaks from cattle produced without growth hormones or genetically modified corn in France, Germany, the United Kingdom, and the United States. In general, European consumers place a higher value on beef from cattle that have not been administered growth hormones and/or fed genetically modified corn than United States consumers. There is a larger divergence between the two cultures with regard to the issue of biotechnology and genetic engineering than with the issue of growth hormones. Results suggest that liberalizing trade policy for hormone-treated beef may be welfare reducing for the European Union.

Food Safety and Risk Perception in a Changing World AgEcon
Roosen, Jutta; Hansen, Kristin; Thiele, Silke.
This paper presents an analysis of food risk perceptions of German consumers over the eleven year period from 1992 to 2002. Using factor analysis, we analyse the respondents general risk attitudes and the specific perception of food safety risks. General risk attitude are described by variables relating to environmental, lifestyle and food risks. Food safety concerns are grouped into concern about use of biotechnology, about residues, about unhealthy eating habits, and about natural contaminants. An ordered probit analysis identifies the characteristics that explain the importance consumers attribute to these different food safety risks. The results reveal that general risk perceptions and knowledge about food safety hazards are highly significant in the...

INFECTIOUS DISEASE, PRODUCTIVITY, AND SCALE IN OPEN AND CLOSED ANIMAL PRODUCTION SYSTEMS AgEcon
Hennessy, David A.; Roosen, Jutta; Jensen, Helen H..
Comparative advantage motivates large trade flows in feeder animals throughout the world. Trade creates externalities when animal diseases can spread beyond the purchasing farm. When growers can choose between open and closed production systems, Nash equilibrium will likely involve socially excessive trading. Supply response to an increase in marginal costs may be positive. While first-best involves marketwide adoption of either an open-trade or closed-farm system, equilibrium may entail heterogeneous systems. If this is the case, then the feeder trade should be banned. Within a farm, we show how risk of infectious disease can create decreasing returns to scale when the technology is otherwise increasing in returns to scale. Control of disease risk...

Market Differentiation Potential of Country-of-origin, Quality and Traceability Labeling AgEcon
Verbeke, Wim; Roosen, Jutta.
Product labeling has gained considerable attention recently, as a means to both provide product-specific information and reduce quality uncertainty faced by consumers, as well as from a regulatory point of view. This article focuses on whether and to what extent origin, quality and traceability labeling is an appropriate way to differentiate food products. The focus is on fresh meat and fresh fish, two mainly generic food product categories with a high degree of credence character. Insights into the potential for market differentiation through origin, quality and traceability labeling are provided and discussed using primary data collected during the period 2000-2005 by means of four consumer surveys. In general, direct indications of quality, including...
