Sometimes authorities are unable to identify rapidly the origin of a tainted product.In such cases, recalls or warnings often apply to all suppliers, even to those thathad not contributed to the contamination. Traceability enables more targetedrecalls by identifying more specically the product's...

Recreation demand models typically incorporate measures of the physical attributes of recreational sites; e.g., Secchi depth or phosphorous levels in case of water quality. Moreover, most studies show that individuals do respond to these physical characteristics in choosing where to recreate....

Manski [13] proposed an approach for dealing with a particular form respondentuncertainty in discrete choice settings, particularly relevant in survey based researchwhen the uncertainty stems from the incomplete description of the choice scenarios.Specically, he suggests eliciting choice...

A Bayesian variable selection procedure is used to control for uncertainty in thespecication of a recreational demand model. In contrast to comparing models basedon the likelihood values with unknown sampling properties (as in, e.g., Egan et al,2009), we propose a model that draws on the...

A commonly observed feature of visitation data, elicited via a survey instrument, is a greaterpropensity for individuals to report trip numbers that are multiples of 5's, relative to otherpossible integers (such as 3 or 6). One explanation of this phenomenon is that some surveyrespondents have...

Random Utility Maximization (RUM) models of recreation demand are typically plaguedby limited information on environmental and other attributes characterizing the available sitesin the choice set. To the extent that these unobserved site attributes are correlated with theobserved characteristics...

We extend Bresnahan and Reiss’s (1991) model of local oligopoly to allow firm entry and exit over time.In our framework, entrants have to incur sunk costs in order to enter a market. After becomingincumbents, they disregard these entry costs in deciding whether to continue operating or to...

A unique data set on home use of computers and the Internet is used to investigate the tradeoffsbetween physically commuting to a work site and telecommuting from home via computers. Thestudy further investigates whether individuals who work from home receive greatercompensation relative to...

The Iowa Department of Public Health has undertaken several independent projects to evaluate various aspects of the labor environment affecting Iowa healthcare over the recent past. This research expands upon the results of these efforts to estimate the effects of a number of wage and nonwage...

Students in majors with higher average quantitative GRE scores are less likely to attend graduateschool while students in majors with higher average verbal GRE scores are more likely to attendgraduate school. This sorting effect means that students whose cognitive skills are associatedwith lower...
