Última What Influences Consumer Choice of Fresh Produce Purchase Location? AgEcon Bond, Jennifer Keeling; Thilmany, Dawn D.; Bond, Craig A.. There is evidence that consumers are increasingly purchasing food directly from local producers, but little is understood about which market-specific, intrinsic, extrinsic, and demographic attributes influence the probability of preferring to purchase fresh produce through direct-market channels. A multinomial logit model is used to analyze a national dataset of fresh produce consumers with a focus on exploring differences among those that prefer to purchase direct always, occasionally (seasonally and as a secondary source), and never. Results suggest that to increase patronage and loyalty of current customers, producers may emphasize the availability of fresh, superior, vitamin-rich, and locally-grown produce at market locations through booth displays,...

This paper explores farmers’ willingness to adopt genetically modified oilseed rape prior to its commercial release and estimates the ‘demand’ for the new technology. The analysis is based upon choice experiments with 202 German arable farmers. A multinomial probit estimation revealed that GM attributes such as gross margin, expected liability from cross pollination, or flexibility in returning to conventional oilseed rape significantly affect the likelihood of adoption. Neighbouring farmers’ attitudes towards GM cropping and a number of farmer and farm characteristics were also found to be significant determinants of prospective adoption. Demand simulations suggest that adoption rates are very sensitive to the profit difference between GM and non-GM rape...

Ano: 2008 URL: http://purl.umn.edu/36771 Attitudes of College Students towards Agriculture, Food and the Role of Government AgEcon Carreira, Rita I.; Mane, R.; Danforth, Diana M.; Wailes, Eric J.. In 2002 and 2007 we surveyed Agribusiness students’ attitudes about agriculture, farming, food and agricultural policies. Responses were analyzed by year and student characteristics including farm background, citizenship and gender. Citizenship was a significant variable explaining differences in agreement with statements. Year and interactions with year were not significant.

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.

The groundwater resource, the drinking water areas and the surface water quality can be protected by measures, e.g. by reductions of pesticide and nutrient applications, conversion of arable land to grasslands or forests etc. The objective of the paper is to estimate the benefits of groundwater protection by the valuation method choice experiments. This method allows for separate estimation and comparison of the different attributes connected to groundwater protection i.e. the effects on drinking water and surface water quality as compared to the benefits from cleaning and treatment of polluted drinking water to make it suitable for drinking water consumption. The results indicate that the benefits are significant, and that the willingness to pay for...

Ano: 2005 URL: http://purl.umn.edu/24587 Incorporating Uncertainty and Cero Values into the Valuation of Protected Areas and Species AgEcon Hurle, Jesus Barreiro; Garcia, Jose Maria Casada; Perez y Perez, Luis. Under the Spanish conservation law, compensation is envisaged for the damage associated with all actions that reduce the quantity or quality of protected areas and species. This paper provides a tool to evaluate the monetary equivalent of this damage. We conduct a contingent valuation exercise to estimate the existence value related to protected areas and species in Aragon. This estimate is then reconsidered including the possibility of zero bids and also the possibility of uncertain preferences for non-familiar goods. Considering these two effects, mean values are reduced significantly giving support to previous recommendations of dividing by two contingent valuation estimates from dichotomous choice question formats.

El mercado de la carne se ha visto afectado por las recientes crisis alimentarias. La decisión del consumo se ve afectada por el precio, y éste por las características del producto y otros factores que pueden influir en la utilidad del consumidor. A través de la metodología de los precios hedónicos, nuestro objetivo es determinar el valor económico asignado por el consumidor a las características de la carne que influyen en su decisión de compra. Se utiliza información proporcionada por dos encuestas a 540 consumidores de la ciudad de Zaragoza en 2001 y 2002. En la estimación econométrica se asume una forma funcional flexible, a partir de una transformación Box-Cox, lo que resuelve el problema de la forma funcional. Los resultados muestran que la...
