When using a willingness-to-pay (WTP) format in contingent valuation (CV) to value watershed restoration, respondents may protest by questioning why they should pay to clean up a pollution problem that someone else created. Using a sample selection interval data model based on Bhat (1994) and Brox, Kumar, and Stollery (2003), we found that the decision to protest and WTP values were correlated. Protest sample selection bias resulted in a 300 percent overestimate of mean WTP per respondent. Using different ad hoc treatments of protesters, protest bias resulted in moderate effects (−10 percent to +14 percent) after controlling for sample selection bias.
We estimate a system-of-equations model designed to measure the interaction between intertemporal patterns of changes in population, employment, and agricultural land densities. The model is applied to West Virginia for the 1990–1999 period. Consistent with recent findings on migration patterns, the results show that jobs followed people. New jobs were captured by commuters, while agricultural land losses were occurring in the commuters’ counties of origin or bedroom communities. However, counties with relatively more profitable and concentrated agricultural enterprises were less susceptible to alternative land use pressure than counties with less productive or fragmented agricultural land. Elasticities indicate population change is elastic, whereas employment and agricultural land density changes are inelastic to factors affecting them. Growth management, when combined with agricultural land retention programs, may be most effective at preserving agricultural land in high growth or potential growth areas.
A method of paired comparison is adapted for use in estimating economic measures of value. The method elicits multiple binary choices for paired items in a choice set. Probability distributions and economic values are estimated nonparametrically and parametri-cally. The method is applied in an experimental context with a choice set composed of four private goods and several sums of money. The sample's median value estimates for the goods are generally not different than the market prices for these goods. People who are in the market for a good value it higher than those not in the market for the good.
Statistical summarizations of literature review databases using meta-regression analysis provide insight into the differences in past estimates of economic variables such as benefits and price elasticities. The panel nature of the data is an issue that has not received adequate attention in past meta-analyses. This paper conceptually and empirically explores the complexity of stratifying data into panels that model the potential correlation and heterogeneity of past outdoor recreation benefit research. Although our tests of three stratifications of the data did not discern panel effects, the inherent complexity of the data maintains a strong presumption of heterogeneous strata.
