Abstract
The two “Renewable Sources” EU Directives (2001/77 and 2009/72) have obliged Italian government to substantially increase the share of RES electricity production. From the economic point of view an interesting question is whether there exists an appreciable consumer’s Willingness to Pay (WTP) in order to use green energy in the electricity production. Focusing on this question, the study is founded on a national survey with 1596 phone interviews made in Italy, at the end of November 2007. The analysis considers three issues. First how the different elicitation affects respondents choices; second, the relationship between a “single point value” and “a valuation distribution”; and finally the gaps between different formats such as: bidding game and dichotomous referendum (single bounded) contingent valuation method. In all the elicitations formats we make a “certainty correction” proposing five degrees of acceptance: definitely yes and no (DY, DN), probably yes and no (PY, PN) and don’t know (DK). In order to apply the quantitative analysis, the original dataset has been appropriately treated, recoding DK, PN and PY responses. Mainly are as follows. We found a significant path dependence in respondents answers due to the elicitation formats and also in a “conservative” way we found a substantial willingness of consumers to partially cover the cost of Italian RES goal.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
