Internet Paid Surveys

Internet Paid Surveys Biography
An increasing number of stated preference surveys are now carried out on the Internet, yet only few studies have compared the results from web-based surveys with results from other survey modes. The main objective of the present paper is to examine the use of Internet as a survey mode for a CVM study aimed at valuing a gain in life expectancy in the context of air pollution. Convergent validity of the web-based survey mode is examined against face-to-face interviews with respect to differences in socio-demographic characteristics, non-response bias, and differences in willingness-to-pay-related parameters. The general result is that the mean and median willingness-to-pay estimates are statistically indistinguishable across the two survey modes while differences in other willingness-to-pay related parameters exist across the two survey samples.
