A Dynamic Principal-Agent Model of Human-Mediated Aquatic Species Invasions 31
MacPherson, Alexander J.; Moore, Rebecca; Provencher, Bill.
This paper presents a dynamic principal-agent model of aquatic species invasions in which a manager, concerned about the spread of invasive species across lakes by boaters, sets interseasonal management controls on a lake-by-lake basis, and boaters make a series of intraseasonal trip decisions to maximize random utility during the course of the season, conditional on the controls imposed by the manager. The results of a simulated invasion of Eurasian watermilfoil (Myriophyllum spicatum) highlight interesting aspects of the optimal management policies under two different management objectives: maximizing boater welfare and minimizing milfoil spread.

A Policy Tool for Evaluating Investments in Public Boat Ramps in Florida: A Random Utility Model Approach 31
Thomas, Michael H.; Lupi, Frank; Harding, David B..
Across the country many people engage in recreational boating. In 2008 there were over 12 million registered recreational boats in the United States, and nearly 8% of these were in Florida (US Coast Guard, 2008). Launching boats from publically available ramps is one of the primary methods of marine access. Within Florida, nearly 25% of all boating related trips in 2007 involved launching a trailered boat from a publically available ramp (Florida Fish and Wildlife Conservation [FWC], 2009). With hundreds of thousands of boating trips from dozens of publically accessible ramps, Lee County planners need analytical tools to understand demand and consumer surplus to assist them in evaluating new and enhanced launch facilities. To accomplish this, we...

ECONOMIC ANALYSIS OF ENVIRONMENTAL REGULATIONS: APPLICATION OF THE RANDOM UTILITY MODEL TO RECREATIONAL BENEFIT ASSESSMENT FOR THE MP&M EFFLUENT GUIDELINE 31
Tudor, Lynne G.; Besedin, Elena Y.; Fisher, Michael; Smith, Stuart.
The present study focuses on a state-wide case study to evaluate recreational benefits from forthcoming effluent limitation guidelines for the Metal Products and Machinery Industry. The study combines water quality modeling and a random utility model to assess how changes in water quality from the regulation will affect consumer valuation of water resources. Based on preliminary results, the MP&M regulation has the potential to generate substantial recreational benefits in Ohio.

Fishing for more understanding: a mixed logit-error component model of freshwater angler site choice 31
Beville, Stephen; Kerr, Geoffrey N..
Recreational anglers are known to seek different types of experiences in different settings. Such preference and behavioural diversity has important management implications. Research methods which assume only a limited degree of preference heterogeneity and impose rigid substitution patterns can impair understanding of individual’s unique decision process and lead to misguided management and policy recommendations. This paper reports results from an internet-based stated preference survey of recreational trout anglers in the North Canterbury Region of New Zealand. A mixed logit model, which simultaneously specifies random parameters plus error components, is used to capture the extent of random preference heterogeneity in systematic utility along with...

Meta Analysis in Model Implementation: Choice Sets and the Valuation of Air Quality Improvements 31
Banzhaf, H. Spencer; Smith, V. Kerry.
We document the sensitivity of welfare estimates derived from discrete choice models to assumptions about the choice set. Such assumptions can affect welfare estimates through both the estimated parameters of the model and, conditional on the parameters, the substitution among alternatives. Our analysis involves estimates of the benefits of air quality improvements in Los Angeles based on discrete choices of neighborhood and housing. We further illustrate the use of meta analysis to document and summarize voluminous information derived from repeated sensitivity analyses.

MONITORING CHOICE TASK ATTRIBUTE ATTENDANCE IN NON-MARKET VALUATION OF MULTIPLE PARK MANAGEMENT SERVICES: DOES IT MATTER? 31
Scarpa, Riccardo; Thiene, Mara; Hensher, David A..
Land management in Alpine Parks provides multifunctional services to separate groups of users. Choice experiments can be used to derive estimates of value for different management attributes. However, little research has been conducted on how frequently respondents ignore attributes used to describe policy management scenarios. We fill this gap using an approach that identifies and compares both serial and choice-task attribute non-attendance addressing five different visitor types. Our results indicate that accounting for choice-task non-attendance significantly improves model fit and yield estimates of marginal WTP with a more plausible pattern of signs and greater efficiency.

The Welfare Effects of Restricting Off-Highway Vehicle Access to Public Lands 31
Jakus, Paul M.; Keith, John E.; Liu, Lu; Blahna, Dale.
Off-highway vehicle (OHV) use is a rapidly growing outdoor activity that results in a host of environmental and management problems. Federal agencies have been directed to develop travel management plans to improve recreation experiences, reduce social conflicts, and diminish environmental impacts of OHVs. We examine the effect of land access restrictions on the welfare of OHV enthusiasts in Utah using Murdock’s unobserved heterogeneity random utility model (Murdock 2006). Our models indicate that changing access to public lands from fully “open” to “limited” results in relatively small welfare losses, but that prohibiting access results in much larger welfare losses.

Thirty years of fleet dynamics modelling using discrete-choice models: What have we learned? 5
Girardin, Raphael; Hamon, Katell; Pinnegar, John; Poos, Jan Jaap; Thebaud, Olivier; Tidd, Alex; Vermard, Youen; Marchal, Paul.
Anticipating fisher behaviour is necessary for successful fisheries management. Of the different concepts that have been developed to understand individual fisher behaviour, random utility models (RUMs) have attracted considerable attention in the past three decades, and more particularly so since the 2000s. This study aimed at summarizing and analysing the information gathered from RUMs used during the last three decades around the globe. A methodology has been developed to standardize information across different studies and compare RUM results. The studies selected focused on fishing effort allocation. Six types of fisher behaviour drivers were considered: the presence of other vessels in the same fishing area, tradition, expected revenue, species...

Valuing Western Australia’s Recreational Fisheries 31
Zhang, Jing; Hertzler, Greg; Burton, Michael P..
Australia by using the data from the newly finished National Survey of Recreational Fishing (2000/2001)(NSRF). There are a number of findings. 1. Socio-economic characteristics of anglers didn’t affect their catch of high quality fish (prize fish, reef fish or key-sport fish) as much as their catch of low quality fish (table fish and butter fish). 2. For a given trip, anglers were willing to pay $1.63, $26.03, $1.03 and $0.53 for the first prize fish, reef fish, key-sport fish or butter fish caught, respectively. 3. The top four valuable fishing sites in the survey period were Geraldton, Esperance, Albany and Broome, with annual access values of $6.45 million, $4.52 million, $3.47 million and $2.47 million, respectively. 4. The per trip estimates are of...
