Última Wildfire and Respiratory Illness: Linking Fire Events and Attributes to Health Outcomes AgEcon Moeltner, Klaus; Kim, Man-Keun; Yang, Wei; Zhu, Erqian Julia. Existing studies on the economic impact of wildfire smoke have focused either on single fire events or entire fire seasons without distinguishing between individual occurrences. Neither approach allows for an examination of the marginal effects of fire attributes, such as distance and fuel type, on health impacts and costs. Yet, improved knowledge of these marginal effects can provide important guidance for efficient wildfire management strategies. This study aims to bridge this gap using detailed information on 35 large-scale wildfires in the California and Nevada Sierras that have sent smoke plumes to the Reno / Sparks area of Northern Nevada over a three-year period. We relate the daily acreage burned by these fires to daily data on local hospital...

Ano: 2011 URL: http://purl.umn.edu/103433 BENEFITS TRANSFER AND COUNT DATA TRAVEL COST MODELS: AN APPLICATION AND TEST OF A VARYING PARAMETER APPROACH WITH GUIDED WHITEWATER RAFTING AgEcon Bowker, James Michael; English, Donald B.K.; Bergstrom, John C.. We combine currently popular count data methods with earlier work by Vaughan and Russell on varying parameter travel cost models to model trip demand and calculate consumer surplus. We test and reject the hypothesis that per trip consumer surplus from guided rafting is invariant to river characteristics. We then develop and test a series of benefit transfer functions against benefits derived from individual river models. Our findings suggest that this flexible form of count data model offers considerable promise as a benefit transfer function.

Ano: 1997 URL: http://purl.umn.edu/16703 The Fast Decay Process in Recreational Demand Activities and the use of Alternative Count Data Models AgEcon Sarker, Rakhal; Surry, Yves R.. Since the early 1990s, researchers have routinely used count data models (such as the Poisson and negative binomial) to estimate the demand for recreational activities. Along with the success and popularity of count data models in recreational demand analysis during the last decade, a number of shortcomings of standard count data models became obvious to researchers. This had led to the development of new and more sophisticated model specifications. Furthermore, semi-parametric and non-parametric approaches have also made their way into count data models. Despite these advances, however, one interesting issue has received little research attention in this area. This is related to the fast decay process of the dependent variable and the associated long...

Agricultural run-off from the Great Barrier Reef catchment area may cause degradation of coral reefs, affecting the tourism sector that relies on healthy reefs for its income generation. A Contingent Behaviour approach is used to determine the effect of reef degradation on demand for recreational dive and snorkel trips, for a case study of the Great Barrier Reef (GBR) in Australia. We assessed how reef degradation affects GBR tourism and to what extent reef-trip demand depends on the visitors' socio-economic characteristics. A count data model is developed, and results indicate that an average visitor would undertake about 60% less trips to the GBR per year, given a combined 80%, 30% and 70% decrease in coral cover, coral diversity and fish diversity,...
