We compare the ability of three preference elicitation methods (hypothetical choices, non-hypothetical choices, and non-hypothetical rankings) and three discrete-choice econometric models (the multinomial logit, the independent availability logit, and the random parameter logit) to predict...

This paper uses a logistic regression model to examine consumer willingness to buy organic and/or GM food products in the context of food attributes that are considered important in the consumption decision. That model is chosen for its mathematical simplicity and because its asymptotic...

This paper concerns the economic assessment of a nonconventional technology to provide a cheap food and/or feed for many developing countries, using wasted resources, i.e. coastal arid areas irrigated directly with seawater to grow a halophyte crop(Salicornia-sos-7). It was cultivated for two...

Seafood consumption in the U.S. has increased over the period 1990 to 2003. A large percentage of the seafood consumed in the U.S. is imported. The most important seafood products imported to the U.S. are shrimp, Atlantic salmon, tilapia, catfish, crayfish, mussels and a mixture of mollusks. In...

Economic Research on Pesticide Use and Specialization in Dairy Farming

O amendoim (Arachis Hypogaea) é uma oleaginosa consumida mundialmente, sendo a quarta mais cultivada. No Brasil, essa cultura já ocupou posição de destaque, mas atualmente o país é apenas o 19° produtor mundial. O estado de São Paulo é responsável por aproximadamente 78% da...

Policies to promote and encourage local foods may take many different shapes depending on both the specific targets and strategies. Some policies, especially at a local level, promote supply-chain vertical and horizontal integration as a comprehensive strategy which aims to help firms pursue...

Human behaviours are driven by two different types of motives: implicit and explicit motives. Psychologists have developed two main tools, namely time pressure and cognitive load, to disentangle the two motives. It implies that the values of willingness to pay (WTP) are sensitive to time...

Construction of the Itaparica dam and reservoir induced changes in the agricultural production systems of the Itaparica micro-region, at the lower-middle São Francisco river basin. Extensive traditional systems were replaced by e.g. irrigated fruit production. However, over twenty years after...

The Markov Chains Model was proposed to analyze stochastic events when recursive cycles occur; for example, when rework in a continuous flow production affects the overall performance. Typically, the analysis of rework and scrap is done through a wasted material cost perspective and not from the...
