Abstract [en]

We analyze Internet and telephone Stated Choice (SC) survey methods in the context of the Swedish value of time study 2008. In this study, extensive piloting and follow up surveys was undertaken to assure high quality data. We use these data and data from the main survey to analyse properties of the different data collection methods. One conclusion is that Internet gives less random error in the SC data. On the other hand, the response rate drops when Internet is the only response and recruiting mode. A mixed mode survey, where Internet is the primary method but where respondents are knowingly subject to a telephone follow up survey, is found to give substantially higher Internet response rates. If the telephone follow up does not include SC questions, the value of time result will still be biased. A large part of this bias seems to be explained by socio-economic data, such as income and age, which are cheaper to collect.
