Are Agricultural Values a Reliable Guide in Determining Landowners’ Decisions to Create Carbon
Forest Sinks?
Provedor de dados: 31
Autores: Shaikh,
Sabina L.; Sun,
Lili; van Kooten,
G. Cornelis.
This research examines the effects of various factors on farmer participation in agricultural tree plantations for economic,
environmental, social and carbon-uptake purposes, and potential costs of sequestering carbon through afforestation in western
Canada. Using data from a survey of landowners, a discrete choice random utility model is used to determine the probability of
landowners’ participation and corresponding mean willingness to accept (WTA) compensation for a tree-planting program. WTA
includes positive and negative benefits to landowners from planting trees, benefits not captured by foregone returns from
agricultural activities on marginal land. Estimates of WTA are less than foregone returns, but even so average costs of creating
carbon credits...

This paper has three main objectives: (1) to investigate whether the four-quadrant approach introduced by Maini (2003) reveals a
useful typology for grouping countries by GDP and forest cover per capita, (2) to determine if the framework can enhance our
understanding of the relationship between forest cover and GDP per capita, and (3) to investigate why countries in the
four-quadrant world occupy different quadrants, and to determine the principal factors affecting country-movement across and
within the individual quadrants. The examination reveals that countries can be classified into four broad categories, and that GDP
and forest cover per capita have a low but consistent level of negative association. After regressing economic, institutional,
social...

DEMAND FOR WILDLIFE HUNTING IN BRITISH COLUMBIA
Provedor de dados: 31
Autores: Sun,
Lili; van Kooten,
G. Cornelis; Voss,
Graham M.
We present estimates of the demand for hunting licenses by residents and non residents in British Columbia for the period
1971– 2000. We obtain estimates of both short-run and long-run price elasticities and discuss their revenue implications for future
fee increases. We further find the demand by non residents to be strongly correlated with U.S. income variation over the business
cycle; however, we find no such role for cyclical income variation for resident hunters. Finally, we demonstrate that hunters
respond differently to conservation surcharges on hunting licenses relative to direct licensing charges, which has implications for
policy makers introducing environmental surcharges in various contexts.

DEMAND FOR WILDLIFE HUNTING IN BRITISH COLUMBIA

We present estimates of the demand for hunting licenses by residents and non residents in British Columbia for the period

future fee increases. We find the demand by non residents to be strongly correlated with U.S. income variation over the business
cycle, but find no such role for cyclical income variation for resident hunters. The ability of the government to increase revenues
from resident hunters turns out to be limited, particularly in the long run, while greater opportunities exist to raise revenues from
U.S. hunters as short- and long-run price elasticities of demand are quite inelastic. We argue that conservation surcharges...

Fuzzy Logic and Preference Uncertainty in Non-market Valuation
Provedor de dados: 31
Autores: Sun,
Lili; van Kooten,
G. Cornelis.
In seeking to value environmental amenities and public goods, individuals often have trouble trading off the (vague) amenity or
good against a monetary measure. Valuation in these circumstances can best be described as fuzzy in terms of the amenity valued,
perceptions of property rights, and the numbers chosen to reflect values. In this paper, we apply fuzzy logic to contingent
valuation, employing a fuzzy clustering approach for incorporating preference uncertainty obtained from a follow-up certainty
confidence question. We develop a Fuzzy Random Utility Maximization (FRUM) framework where the perceived utility of each
individual is fuzzy in the sense that an individual’s utility belongs to each cluster to some degree. The model is then applied to a...

Quality of Life as an Explanation of the Divergence between Ranchers’ ' WTA and WTP for Public
Forage
Provedor de dados: 31
Autores: Sun,
Lili; van Kooten,
G. Cornelis; Voss,
Graham M.
This research provides empirical support for divergence between WTA and WTP, based on results from a 2002 survey of Nevada
ranchers. WTP for public forage and WTA compensation to part with grazing rights are estimated simultaneously, with the
estimators demonstrating a statistically significant divergence while enabling identification of ranch characteristics that influence
the discrepancy in valuations. We conclude that ranching lifestyle (quality of life) accounts for some of the difference between
WTP and WTA.

Divergence between WTA and WTP Revisited: Livestock Grazing on Public Range
Provedor de dados: 31
Autores: Sun,
Lili; van Kooten,
G. Cornelis; Voss,
Graham M.
The research reported here provides further empirical support for the contention that there is a divergence between WTA and
WTP. The conclusion is based on results from a 2002 survey of Nevada ranchers that asked about willingness to pay for public
forage and WTA compensation to part with grazing rights. WTP and WTA are estimated simultaneously, with the estimators used
to demonstrate a statistically significant divergence between WTP and WTA. The simultaneous estimation allows us to identify
ranch characteristics that influence the discrepancy in valuations. Ranch size, public grazing allotment, financial distress, and long
term commitment to ranching are all significant influences on the disparity. We interpret these results both with respect to
general...

The Effect of Uncertainty on Contingent Valuation Estimates: A Comparison
Provedor de dados: 31
Autores: Shaikh,
Sabina L.; Sun,
Lili; van Kooten,
G. Cornelis.
We examine the impact of uncertainty on contingent valuation responses using (1) a survey of Canadian landowners about
willingness to accept compensation for converting cropland to forestry and (2) a survey of Swedish residents about willingness to
pay for forest conservation. Five approaches from the literature for incorporating respondent uncertainty are used and compared to
the traditional RUM model with assumed certainty. The results indicate that incorporating uncertainty has the potential to increase
fit, but could introduce additional variance. While some methods for uncertainty are an improvement over traditional approaches,
we caution against systematic judgments about the effect of uncertainty on contingent valuation responses.
