In a controlled lab experiment, we investigate hypothetical biases in the value of time by comparing stated preference … times and monetary incentives. We find a substantial hypothetical bias with the average SP value of time being only 71% of … the corresponding RP value. The bias is mainly driven by participants who have scheduling constraints during the time of …

Hypothetical bias is one of the main issues bedeviling the field of nonmarket valuation. The general criticism is that …

simultaneously. We combine revealed (travel cost) and stated preference (choice experiment) data within a random utility model … ecological standards. Through a Monte Carlo experiment we show that both use and non-use parameters can be precisely estimated …

of 'hypothetical bias' is still lacking. Based on evidence from economics, economic psychology and the political sciences … hypothetical bias is revisited in the light of these behavioral hypotheses. I find that the hypotheses are generally supported by …

A simple but novel experiment is described examining the impact of interviewer appearance upon stated willingness to …

Selectivity bias caused by protest responses in Contingent Valuation studies can be detected and corrected by means of … effect of protest responses would cause an upwards bias of the final estimates of WTP. …

We present an experiment designed to investigate the presence and nature of ordering effects within repeated response … sample, full factorial study designed to mitigate against misspecification bias and design-induced error variance problems …
