We show here how these modeling decisions lead to significantly different results when estimating the effects of weather and simulating the potential welfare impacts of climate change on outdoor recreation. Using participation data from 1.6 million households in the United States from 2004 to 2009, we estimate the impact of temperature and precipitation on participation decisions for marine shoreline recreational fishing. Results from linear models suggest temperature positively impacts participation and, by implication, climate change is likely to improve welfare associated with outdoor recreation in all regions of our study area. Conversely, nonlinear specifications suggest more days with extreme heat reduce participation and lead to significant declines in welfare under future climate scenarios. Differences in the treatment of how weather enters recreation participation decisions change both the sign and magnitude of welfare effects by nearly $1 billion annually. Differences in data structure, however, only affect the magnitude of welfare impacts but not the sign. Disaggregation of welfare estimates suggests warmer baseline climates are more susceptible to these choices.

Costs that are fixed in the short run, such as expenses for equipment that is used over multiple trips, are typically ignored and implicitly netted out. The resulting net value of recreation trips, or consumer surplus, is appropriate for long‐run analysis when consumers can fully adjust their expenditures. However, in cases where some costs are difficult to adjust in the short run, such as when boat owners do not sell their boats in response to the transient effects of an oil spill, traditional consumer surplus measures underestimate the total welfare change. We explain this underestimation and show how to correct for it by adjusting traditional consumer surplus estimates upward. We illustrate our procedure using a model of recreational boating developed to assess damages from the Deepwater Horizon oil spill. In that case, accounting for boating fixed costs resulted in a 50% increase in estimated value relative to estimates of consumer surplus alone.}, number={4}, journal={American Journal of Agricultural Economics}, publisher={Wiley}, author={English, Eric and Herriges, Joseph A and Lupi, Frank and McConnell, Kenneth and Haefen, Roger H}, year={2019}, month={Apr}, pages={1082–1097} }

Over the past five years, simulation-based estimation and welfare calculation strategies have been developed that enable the Kuhn-Tucker framework to address policy-relevant valuation questions in applications with many quality-differentiated goods. We review these modeling innovations in the context of three generic Kuhn-Tucker specifications that differ in terms of their ability to account for unobserved preference heterogeneity. For illustration, we apply the alternative specifications to Canadian moose hunting data and present parameter and welfare estimates. We conclude the chapter by suggesting important areas for future research within the Kuhn-Tucker framework.}, booktitle={Applications of Simulation Methods in Environmental & Resource Economics}, publisher={Springer}, author={von Haefen, Roger H. and Phaneuf, Daniel J.}, editor={Scarpa, Riccardo and Alberini, AnnaEditors}, year={2005}, pages={135–157} }

Single and double hurdle variants of the repeated discrete choice model are developed and applied to choice experiment and multisite seasonal recreation demand data. Our results suggest that hurdle models can generate significant improvements in statistical fit and qualitatively different policy implications, particularly in choice experiment applications where the proper treatment of serial nonparticipation is relatively more ambiguous.}, number={4}, journal={AMERICAN JOURNAL OF AGRICULTURAL ECONOMICS}, author={Haefen, RH and Massey, DM and Adamowicz, WL}, year={2005}, month={Nov}, pages={1061–1076} }

Parameter and welfare estimates from nested constant elasticity of substitution count data demand system models are presented and compared to estimates from the multinomial approaches developed previously. A significant advantage of the count data estimation strategy over the multinomial-based approaches is that the analyst avoids the difficulties associated with choice occasion specification and interpretation.

This is accomplished by evaluating whether indexes of the environmental resources in each state affect construction expenditures for Federal Aid highways from 1990 to 1994. Statistical analyses suggest that the expenditures for Federal Aid highway construction and repair were impacted by measures of the environment resources or the regulatory activities likely to be associated with environmental mandates. Similar models applied to construction expenditures for state roads did not find the proxy measures for federal regulations as positive influences on cost.}, journal={Journal of Transportation and Statistics}, year={1999}, month={May} }
