Última A Comparison Of Choice Experiments And Actual Grocery Store Behavior: An Empirical Application To Seafood Products AgEcon Hudson, Darren; Gallardo, Rosa Karina; Hanson, Terrill R.. In this paper we compare results from an in-store field experiment and a mail survey choice experiment (CE) to investigate CE’s capacity in predicting grocery store market share. For the comparison, we used three seafood products: freshwater prawns, marine shrimp, and lobster. CE estimates were obtained via four econometric models: the conditional logit, the random parameter logit, the heteroskedastic extreme value, and the multinomial probit. We found that the level of control in the grocery store experiment and the choice of econometric model influenced the capacity of CE to predict grocery store market shares.

The stated choice (SC) and actual revealed pricing/purchase experimental methods were compared for their ability to predict purchasing behavior and willingness-to-pay for freshwater prawns. SC hypothetical bias may be a consequence of difficulties in controlling factors affecting real world situations, small sample sizes and confusion related to the new product.

Ano: 2005 URL: http://purl.umn.edu/35623 Consumers' Willingness to Pay for Treatment-Induced Quality Attributes in Anjou Pears AgEcon Zhang, Huifang; Gallardo, Rosa Karina; McCluskey, Jill J.; Kupferman, Eugene M.. Ethylene treatments provide an effective method for shortening post-harvest ripening periods for winter Anjou pears and allow market availability throughout the year. However, pear quality may vary under different treatments. A sensory experiment and a consumer survey including questions that address valuation, assessments of sensory characteristics, purchasing habits, and demographics were conducted. Analyses indicate that treatment-induced quality losses significantly affect consumers’ willingness to pay (WTP). Mean WTP for each treatment reveals that consumers prefer pears with a six-day ethylene treatment and are willing to pay a premium of $0.25/pound compared to the market price.

Ano: 2010 URL: http://purl.umn.edu/61062 DEMAND ESTIMATION IN THE PRESENCE OF AN UNOBSERVABLE PRODUCT ATTRIBUTE: THE CASE OF MINT QUALITY AgEcon Toro-Gonzalez, Daniel; Yan, Jia; Gallardo, Rosa Karina; McCluskey, Jill J.. This article estimates the demand for mint-flavored gum products using grocery store sales data and accounting for consumers’ valuation of quality. Unobserved product attributes, such as flavor quality, are important elements to consider when estimating the demand for gum. The estimation results suggest that gum is an inelastic product. A positive relationship between willingness to pay and unobserved quality was identified, implying that gum industry should be able to command a premium for higher quality mint flavored products.

Ano: 2012 URL: http://purl.umn.edu/123518 Discrete choice models, which one performs better? AgEcon Gallardo, Rosa Karina; Chang, Jae Bong. For over the last thirty years the multinomial logit model has been the standard in choice modeling. Development in econometrics and computational algorithms has led to the increasing tendency to opt for more flexible models able to depict more realistically choice behavior. This study compares three discrete choice models, the standard multinomial logit, the error components logit, and the random parameters logit. Data were obtained from two choice experiments conducted to investigate consumers’ preferences for fresh pears receiving several postharvest treatments. Model comparisons consisted of in-sample and holdout sample evaluations. Results show that product characteristics hence, datasets, influence model performance. We also found that the...

Ano: 2010 URL: http://purl.umn.edu/61483 Effect of Publicly Released Quality Information for US Hard Red Winter Wheat on Mexican Millers' Welfare AgEcon Gallardo, Rosa Karina; Lusk, Jayson L.; Holcomb, Rodney B.. Entities have been providing quality related information to overseas wheat buyers as a response to the increased requests for this information. This study measures the value of information to Mexican millers. The value to Mexican millers is measured by the difference of the flour mill surplus and compensating variation.

Ano: 2008 URL: http://purl.umn.edu/6869 Increasing U.S. Hard Red Winter Wheat Competitiveness in Latin American Markets AgEcon Gallardo, Rosa Karina; Holcomb, Rodney B.. The United States wheat sector leadership in world markets is facing serious challenges. Canada, Australia, Argentina, the European Union (EU), and the Former Soviet Union (FSU) are growing contenders for international wheat markets. Wheat buyers´ concerns about quality specifications and its consistency have intensified without precedents in the last years. The study focuses on identifying the attributes that wheat buyers most value at the moment of purchase. The study will be done in two stages. The first stage will focus in estimating preferences from actual wheat transactions from different grain-sheds in the HRW growing area. The second stage will focus on the demand from Latin American millers and will estimate their attribute preference and...

RESUMEN: Las sucesivas reformas de la Política Agraria Común (PAC) han diseñado distintos instrumentos de protección para los productos continentales y para los productos mediterráneos en Europa, lo que ha originado diferentes estrategias de ajuste por parte de los agricultores frente a estos procesos. Los empresarios agrarios de zonas donde conviven ambos tipos de productos (continentales y mediterráneos), se ven sometidos a medidas de protección que pueden derivar hacia lógicas económicas contradictorias y constituir un obstáculo para los procesos de ajuste y modernización que se pretenden fomentar desde la UE. Este artículo aborda el estudio de los efectos de las reformas de la PAC en sistemas agrarios andaluces con presencia de producciones...

Ano: 2002 URL: http://purl.umn.edu/28752 The Farm Strategy Approach Towards Competitiveness under the CAP Reforms. The Case of Andalusia in Southern Spain AgEcon Gallardo, Rosa Karina; Ramos, Fernando; Ramos, Eduardo. The evolution of the Common Agricultural Policy (CAP), and its successive Reforms, has caused a loss of both internal coherence and social legitimacy. On the other hand, the Agenda 2000 has situated agriculture within the objective of competitiveness. What may well be asked is whether indeed the different European agricultural systems are converging towards this objective of competitiveness. To be able to reply to this question it is necessary to change from a 'meso' analysis of the CAP to a 'micro' analysis of farms referring to specific regions. Starting from this context and problem, this paper analyses how the agriculture of the region of Andalusia can be affected by the competitiveness approach in an area which is in an advanced process of...

Ano: 2002 URL: http://purl.umn.edu/24963 Willingness-to-Pay for Attribute Level and Variability: The Case of Mexican Millers’ Demand for Hard Red Winter Wheat AgEcon Gallardo, Rosa Karina; Lusk, Jayson L.; Holcomb, Rodney B.; Rayas-Duarte, Patricia. In-person interviews were carried out with Mexican millers who were administered a conjoint-type survey designed to incorporate uncertainty in attribute levels. Two methods were used to model millers’ risk preferences: a modified mean-variance approach and an explicit expected utility approach. Controlling for variability, Mexican millers are willing to pay premiums for increases in quality factors such as test weight, protein content, falling number, and dough strength/extensibility. We find millers are not particularly sensitive to changes in the variability of quality characteristics. Out-of-sample forecasts suggest the mean-variance model provides an accurate depiction of actual Mexican imports.
