A multiple price list is useful for eliciting a Willingness-to-Pay (WTP) and a possible Lower Limit (LL) under which the demand is zero. This multiple price list implies an aggregate demand determined by the number of participants whose WTP is greater than the market price and whose LL is below...

A field experiment was conducted in France to evaluate the impact of health information on fish consumption. A warning revealed the risks of methyl mercury contamination in fish and gave consumption recommendations. A difference-in-differences estimation shows that this warning led to a...

An experiment with different information treatments was conducted in France and Germany to evaluate consumers' willingness to pay (WTP) for food nanotechnology focusing on two applications: nano-fortification with vitamins and nano-packaging. Results show that many consumers in both countries...

Les innovations technologiques dans le secteur agro-alimentaire posent la double question de leur acceptabilité par les consommateurs et de leur mise sur le marché en Europe. Les résultats de travaux récents sur la perception des nanotechnologies dans l’alimentation permettent de...

This paper compares results from a lab experiment and a field experiment conducted in France to evaluate the impact of health information on fish consumption. In both experiments, health information concerns a benefit (omega 3) and a risk (methylmercury). While the lab experiment focuses on two...
