Despite the large use of the travel cost method as estimation technique for the demand for forest recreation, information on price elasticity is only seldom reported. In this way, it is hard to understand if a large consumer surplus could be reflected in income opportunities for the local populations, because it is unknown whether the number of annual trips will decrease as a consequence of price changes. This is particularly relevant in remote rural areas, where few other opportunities for additional earnings are available. This contribution attempts to fill this gap, estimating price elasticities for two different specifications of the cost for travel; a first specification includes cost for travel only, while the second comprise on-site expenditures (such as food and accommodation). Data were collected by means of a questionnaire survey administrated to a sample of local visitors and analysed with a Poisson model. Results suggest that visitors have different sensitivities to distance travelled and to expenses locally sustained, the first being more elastic.

Livestock traceability has increasingly become a focus for the USDA, the National Cattlemen’s Beef Association, high-volume beef-exporting states, and other beef industry stakeholders. The focus on traceability within the United States began after several international animal disease outbreaks and continues to be of importance with African Swine Flu spreading across Asia. Mitigating adverse future disease outbreaks, as well as maintaining export markets through a positive international perception of U.S. beef has become a top priority. Implementing a national disease traceability program would enable the industry to track and reduce the potential losses due to an outbreak. However, such a system comes at a large cost, mainly to cow-calf producers. This study utilizes an equilibrium displacement model (EDM) to determine the impacts of a beef cattle disease traceability system in the United States. Utilizing the EDM allows us to provide a comparison of how the various beef sectors would need to respond to offset the costs of a national disease traceability program.

Complex organics are now commonly found in meteorites, comets, asteroids, planetary satellites, and interplanetary dust particles. The chemical composition and possible origin of these organics are presented. Specifically, we discuss the possible link between Solar System organics and the complex organics synthesized during the late stages of stellar evolution. Implications of extraterrestrial organics on the origin of life on Earth and the possibility of existence of primordial organics on Earth are also discussed.

This paper reports an analysis of the behavior and perception of migrant agricultural workers in relation to central human capacities. Seven dimensions of analysis were aligned to the human central capabilities proposed by Nussbaum. The results showed that physical health and emotions infringe human development of workers. The capabilities of practical reason, affiliation and control over the environment showed discrimination and social segregation. The results provide evidence on the quality of life and general welfare situation of migrant farm workers from a perspective for human development.
