摘要
An experiment was conducted in France to evaluate the impact of health and environmental information on consumers鈥?choices between conventional and organic apples. Results show that additional and precise messages about both pesticides use and pesticides residues significantly impact consumers鈥?choices between both products. The experiment also studied the effect of a new label signaling apples that only use few pesticides compared to conventional apples. With elicited willingness-to-pay, we show that the introduction of this new label increases the average participants鈥?surplus whatever the information context for participants, because of a higher quality compared to conventional apples and a lower price compared to organic products. In order to complement this label, a minimum-quality standard imposing the use of few pesticides is socially optimal when initial participants鈥?knowledge is limited.
