The Effect of Information Choice and Discussion on Consumers' Willingness-to-Pay for Nanotechnologies in Food AgEcon
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 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...

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...

TESTS FOR THE ROLE OF RISK AVERSION ON INPUT USE AgEcon
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 AgEcon
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 AgEcon
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.

THE DESEASONALIZATION OF ANIMAL PRODUCTION AgEcon
Roosen, Jutta; Hennessy, David A..
We document the deseasonalization of animal production in the US and Europe. Hypotheses on causes and consequences of this trend are advanced. They pertain to feed costs, changes in animal productivity and cost fixity of the underlying technology, innovations in genetic control and epidemiology, and the capital intensity of production.

TESTING FOR THE MONOTONE LIKELIHOOD RATIO ASSUMPTION AgEcon
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.

The economic value of food labels: A lab experiment on safer infant milk formula AgEcon
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...

Willingness to pay for genetically modified food and non-food products AgEcon
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 AgEcon
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 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.

SYSTEMIC FAILURE IN THE PROVISION OF SAFE FOOD AgEcon
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 AgEcon
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...
