Measuring the value of time for methadone maintenance clients: willingness to pay, willingness to accept, and the wage rate
通过条件价值评估法，比较了美沙酮维持治疗客户对减少旅行时间的支付意愿、放弃时间的接受意愿以及工资率三种时间价值衡量方式，发现它们之间存在系统性差异。
Three measures of the value of time - willingness to pay (WTP) for a reduction in travel time, willingness to accept (WTA) a monetary compensation to forgo it, and the wage rate - are evaluated and compared. WTP and WTA were estimated from the two-part regressions of time price, using contingent valuation methods with primary survey data. Systematic differences are found in comparisons of WTP and WTA with the wage rate.
