Abstract: The objective of the study is to investigate the effect of the oath script (HO) in an hypothetical Contingent Valuation survey in a Mediterranean country (e.g. Italy). Hence, there were conducted the CE surveys with three treatments: (1) CV without a cognitive task, (2) CV with a CT script, and (3) CV with a HO. The findings showed that the effectiveness of the HO script depends on the participants' socio-demographic characteristics. For instance, it was found that the HO script could help to reduce the hypothetical bias for people who possess a high educational level in contrast with those people with low education and low income. Hence, the findings suggest that the oath script not only does not a guarantee the reduction of the hypothetical bias, but it also does not explain the mixed results found in the previous studies.
