A calibrated model is used to determine the welfare impacts of various regulatory instruments for improving health. The results of a lab experiment are integrated in a partial equilibrium model representing demands for two kinds of fish, one with higher nutritional benefits (canned sardines) and...

We evaluate the impact of different information sequences on participants’ hypothetical willingness to pay (WTP) for food produced using nanotechnology. In three treatment groups, information on the health, societal, or environmental impact linked to nanotechnology was revealed in...

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...

Une expérience a été menée en France et en Allemagne afin d'évaluer le consentement à payer des consommateurs pour les nanotechnologies alimentaires en se concentrant sur deux applications: un nano-enrichissement en vitamines et des nano-emballages. Les résultats montrent que de nombreux...
