Are Agricultural Values a Reliable Guide in Determining Landowners’ Decisions to Create Carbon Forest Sinks? AgEcon
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...

DOES INCLUSION OF LANDOWNERS' NON-MARKET VALUES LOWER COSTS OF CREATING CARBON FOREST SINKS? AgEcon
Shaikh, Sabina L.; Suchanek, Pavel; Sun, Lili; van Kooten, G. Cornelis.
This research examines effects of various factors on farmer participation in agricultural tree plantations for economic, environmental, social and carbon-uptake purposes. Using data from a survey of Canadian agricultural landowners, a discrete choice random utility model is used to determine the probability of farmers' participation and corresponding mean willingness to accept (WTA) compensation for a tree-planting program. WTA includes positive and negative nonmarket benefits to landowners from planting trees. Estimates of WTA are less than foregone agricultural rents, but average costs of creating carbon credits still exceed their projected value under a CO2-emissions trading scheme

Fuzzy Logic and Preference Uncertainty in Non-market Valuation AgEcon
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 AgEcon
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.

Linking Forests and Economic Well-Being: A Four-Quadrant Approach AgEcon
Wang, Sen; DesRoches, C. Tyler; Sun, Lili; Stennes, Brad; Wilson, Bill; van Kooten, G. Cornelis.
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...

Divergence between WTA and WTP Revisited: Livestock Grazing on Public Range AgEcon
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...

DEMAND FOR WILDLIFE HUNTING IN BRITISH COLUMBIA AgEcon
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 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...

DEMAND FOR WILDLIFE HUNTING IN BRITISH COLUMBIA AgEcon
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.

The Effect of Uncertainty on Contingent Valuation Estimates: A Comparison AgEcon
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.
