Resumo(s)
We applied count-data travel cost methods to a truncated sample of visitors, to estimate the average CS per each day of visit of an individual, visiting the Peneda-Gerês National Park to enjoy their natural facilities for recreation purposes. As the
recreation demand was measured in number of days of stay in the park the behaviour of
the dependent variable is very specific. To overcome this situation, we propose the use
of altered truncated count data models or truncated count data models on grouped data
because we found they were better adjusted to our data set. The average individual CS
per day is estimated to be €194 varying between €116 and €448, with Simulated Limits.
This information is useful in the formulation of government policy relating directly to national parks and conservation and the determination of future natural park
management. To our knowledge this is the first attempt to measure the average
recreation net benefits per each day of stay supported by a national park, by using
truncated altered and truncated grouped count data Travel Cost Model based on the
observation of individual (not household) number of days of stay.
