This article explores the combination of laboratory and field experiments in defining a welfare framework and the impact of different regulatory tools on consumer behaviors. First, an overview of strengths and weaknesses raised by the experimental literature show that, for food consumption, lab...

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...

This article shows how experiments revealing information about food quality and safety can contribute to regulatory debates on food and health. After detailing the motivations of regulation for the food sector, we underline the limits of theoretical welfare analysis. Despite challenges from...

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...

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...

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...
