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. Copyright © 2002 John Wiley & Sons, Ltd.
