Economic Feasibility of Commercial Algae Oil Production in the United States
Provedor de dados: 31
Autores: Fischer,
Bart L.; Richardson,

Marc S.
A Monte Carlo simulation model was constructed to analyze the economic feasibility of growing algae as a renewable fuel source.
Increasing growth rates, pond water depth, oil content, and facility size are important for ensuring the economic viability of a
commercial algae facility.

TIMBER HARVEST ADJACENCY ECONOMIES, HUNTING, SPECIES PROTECTION, AND
OLD GROWTH VALUE: SEEKING THE OPTIMUM

Spatial forest management models recognize that nontimber benefits cat1 be influenced by the status of adjacent land. For
instance, contiguous old growth provides habitat, aesthetic value, and environmental services. Conversely, edge areas provide
forage and cover habitat for game and non-game wildlife. However, adjacency externalities are not limited to nontimber concerns.
Larger harvest areas generate average cost savings as fixed harvesting costs are spread across greater acreage, a problem excluded
from most literature on optimal harvesting. Hence, it is typical that economies and diseconomies of adjacency in harvesting occur
simultaneously. This complicates the determination of optimal ecosystem management behavior, which recognizes timber,
aesthetic,...

The Value of Cultural Heritage Sites in Armenia: Evidence from a Travel Cost Method Study
Provedor de dados: 31
Autores: Alberini,
Anna; Longo,
Alberto.
This paper applies the travel cost method to visits to cultural sites in Armenia by domestic visitors. Respondents intercepted at
four cultural monuments provided information on their visitation patterns, experience at the site, perception of the state of
conservation of the monuments, and rating of the quality of the services and infrastructures. We combine actual trips with stated
trips under hypothetical programs that would enhance the conservation of the monuments and improve one of (i) the cultural
experience at the site, (ii) the quality of the infrastructure, or (iii) the quality of the services, and use the combined actual and
stated trips to fit a panel data model. Our investigation shows that that there are significant use values associated with...
