Food safety policy programs often involve communication campaigns that inform the general public about reductions in the probability that negative outcomes will occur in the future. Using a stated-choice survey, we find that people do not fully accept scientific probabilities, but they adjust these to conform with their own probability estimates. Interestingly, this adjusting phenomenon is more pronounced when scientific probabilities are smaller than subjective probabilities, rather than when they are greater. This asymmetric “adjustment” is shown to affect support and willingness to pay for food safety polices.
Simone is a Research Fellow at the Rowett Institute for Nutrition and Health (RINH) since June 2013 and his appointment is part of a growing collaboration between RINH and HERU. He holds a Ph.D. in Economics and Management from the University of Trento in Italy. He previously worked at the Fondazione Eni Enrico Mattei (FEEM) from 2011 to 2012 as a Research Fellow. His research focuses on decision-making processes under risk and uncertainty. In particular, he is interested in the elicitation of subjective probabilities, risk attitudes and time preferences as well as in the investigation of the influence that risk communication has on choice behaviour. He investigates these issues by using laboratory and field experiments. His empirical studies mainly focus on food and environmental issues.
