The Effect of Information Choice and Discussion on Consumers' Willingness-to-Pay for Nanotechnologies in Food
Provedor de dados: 31
Autores: Roosen,   Jutta; Bieberstein,   Andrea; Marette,   Stephan; Blanchemanche,   Sandrine; Vandermoere,   Frederic.
We evaluate the impact of different information sequences on participants’ hypothetical willingness to pay (WTP) for food produced using nanotechnology. In three treatment groups, information on the health, societal, or environmental impact linked to nanotechnology was revealed in different sequences: an imposed order, a chosen order, and a chosen order after a discussion among participants. Results show that information choice is important. While in the imposed order, the first information revealed has no effect on WTP, the information chosen first has a strong impact. Discussion has no further impact. Health information was a priority and significantly decreased WTP, while societal and environmental information did not significantly influence WTP.

Market Differentiation Potential of Country-of-origin, Quality and Traceability Labeling
Provedor de dados: 31
Autores: 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...

AN ANALYSIS OF THE RETIREMENT-CONSUMPTION PUZZLE FOR FOOD-AT-HOME AND AWAY-FROM-HOME EXPENDITURES IN GERMANY
Provedor de dados: 31
Autores: 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...

TESTS FOR THE ROLE OF RISK AVERSION ON INPUT USE
Provedor de dados: 31
Autores: Roosen,   Jutta; Hennessy,   David A.
Agricultural inputs can create negative externalities.  For risk averting agents, risk will alter production decisions while the existence of institutions to insure against adverse states of nature will likely restore decisions toward levels under risk neutrality.  In this paper, conditions are identified on a stochastic technology to test that risk averters choose smaller input levels than risk neutral agents, and that an increase in risk aversion reduces input use.  A robust statistical method (Klecan, McFadden, and McFadden) to test for dominance is adapted to stochastic production relations.  It is found that the first hypothesis is likely true for nitrogen application on Iowa corn.  Weaker evidence is found in favor of the second hypothesis.

Of Experts, Politicians and Beasts: Setting Priorities in Farm Animal Conservation Choices
Provedor de dados: 31
Autores: Fadlaoui,   Aziz; Roosen,   Jutta; Baret,   Philippe V.
We consider the choice of farm animal breeds for conservation programmes. Based on an analysis of past decisions in EU member countries to enter breeds into the conservation programmes of rural development plans and based on the results of an expert survey among breed societies and scientists, we find an inconsistency in the valuation of breed characteristics. Policy makers seem to be less concerned about considering true extinction risk and diversity and more about cultural values and about means to benefit a larger number of farmers for raising rare breeds.

The Choice of Fish Species: An Experiment Measuring the Impact of Risk and Benefit Information
Provedor de dados: 31
Autores: Marette,   Stephan; Roosen,   Jutta; Blanchemanche,   Sandrine; Verger,   Philippe.
An experiment was conducted in France to evaluate the impact of health information on consumer’s choice. Fish have positive and negative health attributes, and we focus on fish species of diverging risk-benefit ratios. Successive messages revealing risks (methylmercury) and benefits (omega-3s), along with consumption recommendations, were delivered to experiment participants. Results show significant differences in reaction among participants depending on the sequencing order of information on risks and benefits. The results of the experiment are combined with a partial equilibrium model to determine the value of information. Acknowledging adjustments of equilibrium prices, health information is shown to have significant value to consumers.

TESTING FOR THE MONOTONE LIKELIHOOD RATIO ASSUMPTION
Provedor de dados: 31
Autores: Roosen,   Jutta; Hennessy,   David A.
Monotonicity of the likelihood ratio for conditioned densities is a common technical assumption in economic models. But we have found no empirical tests for its plausibility. This paper develops such a test based on the theory of order-restricted inference, which is robust with respect to the correlation structure of the distributions being compared. We apply the test to study the technology revealed by agricultural production experiments. For the data under scrutiny, the results support the assumption of the monotone likelihood ratio. In a second application, we find some support for the assumption of affiliation among bids cast in a multiple-round Vickrey auction for a consumption good.

Autores: Goldberg,   Isabell; Roosen,   Jutta; Nayga,   Rodolfo M., Jr.
Enterobacter sakazakii, a pathogen that can be found in powdered infant milk formula, can cause adverse health effects on infants. Using Vickrey auction, this study examines parents' willingness to pay (WTP) for a quality assurance label on powdered infant milk formula. The influence of ambiguity with the incidence rate information and provision of safe-handling information on WTP are also evaluated using three experiments/treatments. The mean price premium parents are willing to pay for the safer and quality assurance labelled powdered infant milk formula ranges from 61 to 133 Eurocents per 100 grams depending on the treatment. While no ambiguity effects are generally found, provision of safe-handling information has a significant influence on WTP. When...

Autores: Christoph,   Inken B.; Roosen,   Jutta; Bruhn,   Maike.
This paper presents estimates of consumers’' willingness to pay for a GM food and non-food product based on data collected in a choice experiment. The choice experiment was part of a survey of 1510 randomly selected consumers in Germany that was mailed in spring 2005. Attitudes towards gene technology, institutions and technical progress were measured using 22 items. A factor analysis revealed five factors describing consumer attitudes: support, risk, trust, attitude towards technical progress and attitude towards technical innovation. Based on these factors we identify four different classes of consumers in a latent class model for both products. Analysis of these classes shows strong differences between willingness to pay estimates for benefits compared...

SEASONALITY, CAPITAL INFLEXIBILITY, AND THE INDUSTRIALIZATION OF ANIMAL PRODUCTION
Provedor de dados: 31
Autores: Roosen,   Jutta; Hennessy,   David A.
Among the prominent recognized features of the industrialization of animal production over the past half century are growth in the stock of inflexible or use-dedicated capital as an input in production and growth in productivity. Less recognized is a trend toward aseasonal production. We record the deseasonalization of animal production in the United States and Europe over the past 70 years. We also suggest that (a) lower seasonality can precede or Granger-cause increased productivity because of increased capital intensity, and (b) productivity improvements can Granger-cause lower seasonality. Process (a) should be more likely earlier in the industrialization process. For U.S. dairy production, our empirical tests find some evidence that process (a)...

AN EQUILIBRIUM ANALYSIS OF ANTIBIOTICS USE AND REPLANTING DECISIONS IN APPLE PRODUCTION
Provedor de dados: 31
Autores: 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
Provedor de dados: 31
Autores: 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.

SYSTEMIC FAILURE IN THE PROVISION OF SAFE FOOD
Provedor de dados: 31
Autores: Hennessy,   David A.; Roosen,   Jutta; Jensen,   Helen H.
Many deficiencies in the capacity of a food system to deliver safe products are systemic in nature. We suggest a taxonomy of four general ways in which a systemic failure might occur. One relates to the connectedness, or topology, of the system. Another arises from mistrust on the part of downstream parties concerning signals on product attributes, production processes, and the performance of regulatory mechanisms. A third arises when asymmetric information leads to low incentives for preserving food quality. Finally, inflexibilities in adapting to different states of nature may leave the system vulnerable to failures. Innovations in information technology and institutional design may ameliorate many problems, while appropriate trade, industrial...

Tax, Subsidy, and/or Information for Health: An Example from Fish Consumption
Provedor de dados: 31
Autores: Marette,   Stephan; Roosen,   Jutta; Blanchemanche,   Sandrine.
A calibrated model is used to determine the welfare impacts of various regulatory instruments for improving health. The results of a lab experiment are integrated in a partial equilibrium model representing demands for two kinds of fish, one with higher nutritional benefits (canned sardines) and one with higher contamination risks (canned tuna) in France. In the laboratory, information about health effects leads to a statistically significant decrease (increase) in the willingness to pay for tuna (sardines). Simulations with the laboratory results show that, for most cases, a per-unit tax on tuna and a per-unit subsidy on sardines without any information revealed to consumers lead to the highest welfare, because both the tax and subsidy directly...

REGULATION IN QUALITY DIFFERENTIATED MARKETS: PESTICIDE CANCELLATIONS IN U.S. APPLE PRODUCTION
Provedor de dados: 31
Autores: Roosen,   Jutta.
If agricultural output results from non-separable multiproduct technologies, environmental regulation can change the set of possible output combinations.  This will be important when regulation affects the quality composition of a crop.  As a result, market and welfare changes have to be assessed in technology-related markets.  We present a model that serves to estimate the economic impacts in such instances and use it in the assessment of pesticide regulation in the U.S. apple industry.  Impacts for four pesticide cancellation scenarios are assessed.  It is shown that changes in the quality of a crop lead to significant market reallocation effects.

MARKETING OF SAFE FOOD THROUGH LABELING
Provedor de dados: 31
Autores: Roosen,   Jutta.
After a series of food safety crises during the 1990s, regulators, producers, and retailers alike are trying to regain consumer confidence by redesigning legislation and quality-assurance programs.  These programs focus on process innovation, traceability, and identity preservation of products.  This paper reviews current developments in the European food and retail industry.  Hypotheses on the link between structural adjustments in the food production and marketing chain and the provision of safe food emerge.  In addition, we report results from a survey on consumer perception of food-safety attributes and discuss the opportunities for and limits of marketing safe food through labels.

CONSUMER DEMAND FOR AND ATTITUDES TOWARD ALTERNATIVE BEEF LABELING STRATEGIES IN FRANCE, GERMANY, AND THE UK
Provedor de dados: 31
Autores: 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....

A REGIONAL ECONOMETRIC MODEL OF U.S. APPLE SUPPLY AND DEMAND
Provedor de dados: 31
Autores: 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.

INFECTIOUS DISEASE, PRODUCTIVITY, AND SCALE IN OPEN AND CLOSED ANIMAL PRODUCTION SYSTEMS
Provedor de dados: 31
Autores: 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...

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.

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.

Studies in the area of health economics and public health have shown that low socioeconomic status (SES) and poverty are related to lower levels of health. Attempts to explain these differences have often made reference to the observation that poor health behaviours cluster in low SES respectively poverty groups. However, relatively little attention has been paid to the defining concept of SES and its appropriate measurement. Therefore data from the German Socio-Economic Panel are used to analyse the relationship between two multidimensional measurements to describe a) poverty respectively b) a low SES and health behaviour, including dietary behaviour, weight status and health behaviour in general. This study shows that both multidimensional indicators...

Consumers' preferences for meat quality attributes such as color influence their purchasing decisions. Better understanding of consumer preferences can help meat processors and others attain effective product development and marketing and inform public policy decisions on nutrition and food safety education. Modified atmosphere packaging extends the shelf-life of fresh meat and, with the inclusion of carbon monoxide, achieves dramatic color stabilization. The value that US and German consumers' place on ground beef packaging techniques was quantifies by means of non-hypothetical choice experiments.

A HAZARD ANALYSIS OF CONSUMERS’ SWITCHING BEHAVIOUR IN GERMAN FOOD RETAILING FOR DAIRY PRODUCTS
Provedor de dados: 31
Autores: 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...

CONSUMERS' VALUATION OF INSECTICIDE USE RESTRICTIONS: AN APPLICATION TO APPLES
Provedor de dados: 31
Autores: 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.

Voluntary environmental agreements have been popular with government agencies in several countries. However, many questions remain about their efficiency as a regulatory tool. Recent analyses suggest that they are more effective than conventional regulatory or economic approaches when dealing with diffuse pollution and when innovation processes at the source are necessary to define effective regulation. This paper applies an activity-based framework to assess the contribution of such a voluntary agreement to the environmental performance of farms participating in a whole farm plan in the Southern part of Belgium. Using a cross-section of 52 farms, our results show that farms entering into environmental agreements are environmentally more efficient than...

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.

A COST-BASED MODEL OF SEASONAL PRODUCTION, WITH APPLICATION TO MILK POLICY
Provedor de dados: 31
Autores: 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...

Measuring Consumer Willingness to Pay for a Health Risk Reduction of Salmonellosis and Campylobacteriosis
Provedor de dados: 31
Autores: Goldberg,   Isabell; Roosen,   Jutta.
This paper presents an application of the contingent valuation method (CVM) and choice experiments (CEs). We examine consumer willingness to pay (WTP) for different health risk reduction levels of Salmonellosis and Campylobacteriosis acquired from the consumption of chicken breast. We test for the embedding effect. The embedding effect was not found in the CVM format. It was however present in the CEs. The WTP values in the CVM format rages from Euro 1.29 to 3.34, whereas the WTP obtained by the CEs ranges from Euro -0.16 to Euro 6.68 depending on the disease and the corresponding risk reduction levels.

Food Safety and Risk Perception in a Changing World
Provedor de dados: 31
Autores: 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...
