CONSUMER INTENTIONS OF BUYING POULTRY MEAT UNDER PERCEIVED BIOLOGICAL, CHEMICAL OR TECHNOLOGICAL RISK IN FINLAND AgEcon
Heikkila, Jaakko; Pouta, Eija; Forsman-Hugg, Sari; Makela, Johanna.
The study focuses on various types of food safety risks: biological (zoonoses), chemical (chemical treatment of the meat) and technological (use of genetically modified feed). The emphasis was on how the perceived risks affect the purchase intentions in the case of broiler meat. In the case of each risk products the attitude-level variables had importance in explaining the buying intentions. The heterogeneity of the respondents regarding the purchase intentions of risk products was analysed by latent class logistic regression that included all three risk products. About 60% of the respondents belonged to the group of risk avoiders in which the purchase intention of risk food was significantly lower than in the second group of risk neutrals in which 64% of...

An Ordinal Regression Model using Dealer Satisfaction Data AgEcon
Staus, Alexander.
This article analyses dealer satisfaction data in the agricultural technology market in Germany. The dealers could rate their suppliers in the ’overall satisfaction’ and in 38 questions which can be summarized in 8 dimensions. An ordinal regression model which is also known as the proportional odds model is used to analyse the ordinal scaled rating of the dealers. The ordinal regression model is a well examined method in econometric theory, but many authors prefer using a linear regression model due to better interpretation, even the assumptions of a linear regression do not fit the data. Since the estimated coefficients of an ordinal regression model can not be properly interpreted we show other methods for a better insight of the relationship of the...

Factors Influencing Cotton Farmers’ Perceptions about the Importance of Information Sources in Precision Farming Decisions AgEcon
Velandia, Margarita M.; Lambert, Dayton M.; Mendieta, Maria P.; Roberts, Roland K.; Larson, James A.; English, Burton C.; Rejesus, Roderick M.; Mishra, Ashok K..
Information generated by precision farming technologies is of particular importance to producers. Precision farming technologies implies the ability to improve the management of production factors using site-specific information. This study examines factors influencing cotton farmers’ perceptions about the importance of crop consultants, farm input dealerships, Extension, other farmers, trade shows, the Internet and printed news/media for making precision farming decisions using a rank ordered logit model (ROLM). Results suggest that age, land tenure, income, percentage of income from farming, and location may affect farmers’ perceptions about the importance of different information sources when making decisions about precision farming technologies....

Cow-Calf Producer Risk Preference Impacts on Retained Ownership Strategies AgEcon
Pope, Kelsey Frasier; Schroeder, Ted C.; Langemeier, Michael R.; Herbel, Kevin L..
Considerable efforts have been made to provide cow-calf producers with information to help them make informed decisions about adding value to calves. Despite demonstrated market incentives to retain calves, many producers still sell right after weaning. We postulate this observed behavior is related to producer risk aversion. Our study concludes risk aversion is an important factor affecting calf retention as the most risk-averse producers have more than a 60% probability of selling calves at weaning and the most risk tolerant have less than a 20% probability of selling at weaning.

Investigating Changes in Canadian Consumers' Food Safety Concerns, 2003 and 2005 AgEcon
Veeman, Michele M.; Li, Yu.
Building on the results of an initial analysis of risk ranking data collected from a representative group of some 850 Canadian respondents in early 2003, this study assesses a similar set of risk ranking questions applied to a somewhat larger representative group of some 1500 Canadians in late 2005. We also compare the 2003 and 2005 risk rankings. In both surveys, risk rankings for eight food safety issues (bacteria contamination, pesticide residuals, use of hormones in food production, use of antibiotics in food production, BSE (mad cow disease), food additives, use of genetic modification/engineering in food production, fat and cholesterol in food) and six environmental safety issues (water pollution by chemical run-offs from agriculture, soil...

Las preferencias discontinuas en los experimentos de elección: impacto en el cálculo de la prima de los programas agroambientales AgEcon
Espinosa-Goded, Maria; Barreiro-Hurlé, Jesús.
En los experimentos de elección se presupone que los individuos consideran todos los atributos que describen un bien a la hora de escoger su opción preferida. Sin embargo, existe evidencia de que los individuos pueden obviar algún atributo. Este trabajo investiga el impacto derivado de las preferencias discontinuas en las estimaciones de la compensación necesaria para acogerse a la medida agroambiental relativa a la siembra de leguminosas en secano. La consideración de las preferencias discontinuas mejora la bondad de ajuste de los modelos, sin embargo únicamente afecta de manera significativa a la compensación demandada por uno de los cuatro atributos no monetarios que definen el programa agroambiental para la submuestra de los agricultores no...

Integrating Routine, Variety Seeking and Compensatory Choice in a Utility Maximizing Framework AgEcon
Adamowicz, Wiktor L.; Swait, Joffre.
Given the large number of choices that consumers make each day it seems likely that they will generally adopt decision strategies that minimize cognitive effort, particularly with low price products such as most items found in a supermarket. One such strategy may be to simply choose what has been chosen in the past, i.e. to fall into a pattern of routine choices or decisions. In contrast, there may be preferences for variety in markets for low price, highly differentiated goods. We develop a conceptual and empirical model of routine choice, and the factors that result in transitions to two strategies other than routine selection, to wit, utility maximizing choice among available alternatives and a variety seeking strategy. The empirical approach we employ...

Market outlet choices in the context of changing demand for fresh meat: implications for smallholder inclusion in pork supply chain in Vietnam AgEcon
Lapar, Ma. Lucila A.; Toan, Nguyen Ngoc; Que, Nguyen Ngoc; Jabbar, Mohammad A.; Tisdell, Clement A.; Staal, Steven J..
This paper reports on the findings of a study to investigate market outlet choice decision-making of urban consumers in Vietnam with regards to fresh pork purchases and generate empirical evidence on factors that influence these choices. Data from a survey of 600 consumers in Hanoi and Ho Chi Minh City was used to estimate a multinomial logit model of market outlet choice based on three alternatives: traditional temporary market outlets, permanent open markets, and modern retail outlets. Results suggest that market outlet choice by consumers of fresh pork in urban cities of Vietnam is conditioned by factors related to mobility and level of affluence, time budgets, concerns about food safety and hygiene, proximity to market outlets, and geographical...

Modeling Yeah- and Nay-Saying to Alternatives in Conjoint Experiments AgEcon
Hu, Wuyang.
Using a series of hurdle choice models, this study considers both nay-saying and yeah-saying to alternatives offered in a conjoint experiment. These behaviors are characterized by respondents persistently choosing the no-choice alternative or choosing at least one of the non-empty options offered in a survey. Results show that jointly consider nay-saying and yeah-saying in a two-hurdle model drastically improves model fit; welfare implications based on hurdle models are also different from those based on models without hurdle specification.

Will Changing Demographics Affect U.S. Cheese Demand? AgEcon
Davis, Christopher G.; Blayney, Donald P.; Dong, Diansheng; Yen, Steven T.; Johnson, Rachel J..
U.S. cheese consumption has grown considerably over the last three decades. Using a censored demand model and Nielsen Homescan retail data, this study identifies price and non-price factors affecting the demand for differentiated cheese products. Own-price and expenditure elasticities for all of the cheese products are statistically significant and elastic. Results also reveal that a strong substitution relationship exists among all cheese products. Although demographic influences are generally smaller than those related to prices and expenditures, empirical findings show that household size, college educated female heads of household who are age 40 and older, residing in the South, Central, and Western regions of the United States, as well as Black heads...

Testing for a Supply Constraint to Fertility: Interpreting the Up to God Response to the Survey Question on Desired Family Size AgEcon
Sinha, Nistha.
The paper outlines a methodology that allows us to determine whether couples’ fertility is supply constrained based on the response they give to the subjective desired family size question. The central idea of the paper is that, when faced with the desired family size question, both constrained and unconstrained couples compare their demand for children with knowledge of their biological supply and unconstrained couples respond with a number while constrained couples respond with a qualitative response such as, “It is Up to God” (UTG), that essentially conveys the notion of demanding as many children as the supply function can yield. I then test this interpretation using data from Bangladesh. I find that controlling for demand side characteristics,...

Mapping preferences for the restoration of environmental damage caused by illegal dumping AgEcon
Campbell, Danny; Sinclair, Victoria.
In this paper we use a discrete choice experiment to elicit the economic benefits associated with restoring environmental damage caused by illegal dumping activities. Our study focuses on an extensive rural upland area close to Belfast, where illegal dumping activities are prevalent. Using a random parameters logit model to account for unobserved taste heterogeneity, we exploit the panel nature of the dataset to retrieve partworths, or willingness to pay (WTP) values, for every individual in the sample. We subsequently investigate the existence of spatial dependence of these estimates. As a means of benefit transfer, we also employ geostatistical methods to extend across the whole of the study area the WTP estimates derived from the collected data. The...

Why Don't Farmers Adopt Precision Farming Technologies in Cotton Production? AgEcon
Paudel, Krishna P.; Pandit, Mahesh; Mishra, Ashok K.; Segarra, Eduardo.
We used the 2009 Southern Cotton Precision Farming Survey data collected from farmers in twelve U.S. states (Alabama, Arkansas, Florida, Georgia, Louisiana, Missouri, Mississippi, North Carolina, South Carolina, Tennessee, Texas, and Virginia) to understand why farmers do not adopt seemingly profitable precision farming technology. Farmers provided cost, time constraint, satisfaction with the current practice and other as reasons for not adopting precision farming technology. Results from a multinomial logit regression model indicated that manure application on field, more formal education, larger farm size, participation in conservation easement or agricultural easement generally decreases the probability of nonadoption of precision agriculture in cotton...

THE INFLUENCE OF ATTRIBUTE CUTOFFS ON CONSUMERS’ CHOICES OF A FUNCTIONAL FOOD AgEcon
Ding, Yulian; Veeman, Michele M.; Adamowicz, Wiktor L..
This study investigates evidence of non-compensatory preferences by incorporating attribute cutoffs into the modeling of consumer choices in the context of food with health-related attributes (omega-3 content) that may be associated with fortification or may result from genetic modification (GM). Data for this study were collected through a nation-wide internet-based survey drawn from a representative panel of Canadian households maintained by a major North American marketing firm. In addition to querying respondents on their perceptions and attitudes regarding food and health, choices of canola oils are elicited using a stated choice experiment in which product alternatives are identified based on attributes of price, country of origin, omega-3 content...

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...

Can Co-Management Improve the Governance of A Common- Pool Resource? Lessons From A Framed Field Experiment in A Marine Protected Area in the Colombian Caribbean AgEcon
Moreno-Sanchez, Rocio del Pilar; Maldonado, Jorge Higinio.
Complexities associated with the management of common pool resources (CPR) threaten governance at some marine protected areas (MPA). In this paper, using economic experimental games (EEG), we investigate the effects of both external regulation and the complementarities between internal regulation and non-coercive authority intervention—what we call co-management—on fishermen’s extraction decisions. We perform EEG with fishermen inhabiting the influence zone of an MPA in the Colombian Caribbean. The results show that co- management exhibits the best results, both in terms of resource sustainability and reduction in extraction, highlighting the importance of strategies that recognize communities as key actors in the decision-making process for the...
