Eco-labels and Quality in Wine

Eco-labels are part of a new wave of environmental policy that emphasizes information disclosure as a tool to induce environmentally friendly behavior by both firms and consumers. Little consensus exists as to whether eco-certified products are actually better than their conventional counterparts. This study seeks to understand the link between eco-certification and product quality. We use data from three leading wine-rating publications (the Wine Advocate, Wine Enthusiast, and Wine Spectator) to assess quality for 74,148 wines produced in California between 1998 and 2009. Our results indicate that eco-certification is associated with a statistically significant increase in wine quality rating. Being eco-certified increases the scaled score of the wine by 4.1 points on average.
