The problem of estimating the expected net benefits of an unlimited-access campus transit pass, which would also fund an increase in critically needed services, is an example of the problem of estimating the value of a public good. Students at Western Washington University in Bellingham, Washington, used a referendum-format contingent valuation survey to measure students' willingness to pay (WTP) for a mandatory transit pass. Responses by 935 students (a 44.7% response rate) were analyzed with censored logistic regression and revealed a mean WTP of $32.08 per academic quarter (corrected for estimated self-selection bias) for the proposed program. The program could actually be provided by contract with the local transit agency for $20.00 per student per quarter. Thus the estimated net benefit per student per quarter is $12.59, or $428, 624 across the campus population. On-campus residents and those who commute via bus or bicycle showed higher WTP. WTP was substantially lower for those who live more than 10...
