| The purpose of this paper is to address a problem that may arise with the assumption of a continuous spatial market in the TCM model. We find that this assumption can be challenged by geographical limitations that an area of study might have. Particularly for islands (or isolated island-like areas) that have a valuable non-market resource or good, the spatial market characteristic of the TCM model might be limited or truncated. The geographical truncation limits the observed maximum travel cost of the demand curve falsely implying a lower WTP than otherwise. The study uses a dichotomous choice CVM to confirm that the resulting demand schedules from the TCM underestimates WTP for day trips to the Caribbean National Forest in Puerto Rico. This results in a... |

| Recognition of the benefits to society supported by estuary ecosystem functions and services, and threats to these benefits posed by human activities, has led to various public programs to restore and protect estuaries and the federal, state and local levels. As available budgets shrink, program administrators and public elected officials struggle to allocate limited restoration and protection funds to the highest priority areas. Economic benefit and cost information can provide useful inputs into this decision-making process by quantifying estuary restoration and protection benefits and costs in commensurate terms. In this paper, a combined actual and intended travel behavior model is described that can be applied to estimate the recreational fishing... |

| A combined telephone contact-mail booklet-telephone interview of California and New England households regarding their willingness to pay for fire management in California and Oregon's old-growth forests was performed to test hypotheses regarding the spatial extent of the public goods market. Using a multiple-bounded contingent valuation question, the study found that New England households' annual willingness to pay for the California and Oregon programs was statistically different from zero. This analysis points out that households receive benefits from fire protection of old-growth forests in states other than their own. In this case study, limiting the survey sample to state residents where the National Forest is located would reflect about 20% of... |

| Economic efficiency has become more visible in national forest plans because of new planning regulations implemented by the Reagan administration. This paper investigates economic efficiency analyses and whether such information influences U.S. Forest Service decisions. The findings indicate that there are substantial errors in estimates of the net present value of wilderness and that there is no association between the sign of net present value and decision makers recommendations about wilderness designation. These findings are consistent with the hypothesis that an economic efficiency information requirement will not insure its use in decision making unless the incentives facing managers change. |

| Recent efforts to refine the concept of existence value and to empirically measure it has led to an unnecessary narrowing of the concept of existence value. This paper uses the literature on public goods to argue that existence value is a much broader concept than proposed by several authors. Two commonly used but different empirical approaches to measuring existence values are compared and shown to lead to statistically different decompositions of total value between use and existence categories. |

| While data used in hedonic property models are inherently spatial in nature, to date the majority of past regression analyses have used OLS models that overlook possible spatial dependence in the data when estimating implicit prices for environmental hazards. This paper explicitly addresses spatial dependence in a hedonic property model. We use robust testing procedures to determine the existence and type of spatial dependence in our OLS model. After identifying the nature of the spatial dependence, OLS estimates of the implicit price of wildfire risk are compared to implicit prices obtained using a spatial error model with three different spatial weighting matrices. Spatially corrected estimates of implicit prices are often found to be nearly the same as... |

| Many times economists are asked to estimate the demand for new consumer goods or services for which no market data exists. Typically market researchers and economists answer this challenge using surveys that ask about intended purchases (Louviere, et al. 2000) or what has become known as stated preference (SP) data. Tying this data to revealed preference (RP), or actual behavior, has been a target in a number of studies. Simplistic calibrations have been investigated in past RP-SP studies, such as Loomis, et al. 2001. This paper offers an alternative solution that allows the magnitude of the calibration correction to vary based on Klein and Sherman's (1997) Orbit procedure. This paper extends the original Orbit procedure of Klein and Sherman by... |

| Inclusion of multi-destination and multi-purpose visitors has an appreciable influence on a standard count data travel cost model derived estimate of willingness to pay but the differences are not statistically significant. We adapt a more general travel cost model (TCM) of Parsons and Wilson (1997) that allows for inclusion of multi-destination visitors as incidental demand to allow estimation of an unbiased measure of single and multi-destination willingness to pat for whale viewing using a single pooled equation. The primary purpose trip values from the standard TCM and simple generalized TCM model are identical at $43 per person per day and neither are significantly different from the $50 day value from a generalized model that distinguishes between... |

| A recreation allocation model is developed which efficiently selects recreation areas and degree of development from an array of proposed and existing sites. The model does this by maximizing the difference between gross recreation benefits and travel, investment, management, and site-opportunity costs. The model presented uses the Travel Cost Method for estimating recreation benefits within an operations research framework. The model is applied to selection of potential wilderness areas in Colorado. This example is then extended to show the model's capability in budget analysis and in planning to meet recreation targets. |

| In a recent paper in this Journal entitled "Economic Efficiency vs. Distributive Equity: The Sagebrush Rebellion" Obermiller provides misleading evidence about the role of efficiency criterion in land use allocations by the Bureau of Land Management (BLM). In using this "evidence" he comes to conclusions that miss other important economic explanations for the so-called Sagebrush Rebellion. A reader unfamiliar with the actual economic analyses performed by BLM might be led to believe that the field offices' active use of efficiency as a decision criterion to implement the Federal Land Policy and Management Act (FLPMA) is one explanation of the origin of the Sagebrush Rebellion. Evidence is presented herein that shows little or none of the efficiency... |
