Geographical indications (GIs) convey information about the place of production as a proxy for the attributes of agricultural products. We define the informational content of the GI proxy as its capacity to describe the tangible characteristics of production sites, instead of random noise or intangible factors from political bargaining about designation (i.e., lobbying effects). We estimate econometrically the informational content of wine‐related GIs for the Cote d'Or region of Burgundy, France. We show that GIs signal vineyard attributes with high precision, while we find some persistent bias from lobbying effects. We also study alternative classifications, from history and from simulations, which reveal a significant increase in the informational content of GIs over the last hundred years or so, and provide guidelines for better designated GIs in the future.

地理标志的信息内容

地理标志 (GI) 传达有关生产地点的信息，作为农产品属性的代表。我们将 GI 代理的信息内容定义为其描述生产地点有形特征的能力，而不是随机噪音或有关指定的政治谈判（即游说效应）的无形因素。我们通过计量经济学估计了法国勃艮第 Cote d'Or 地区与葡萄酒相关的地理标志的信息含量。我们表明地理标志以高精度表示葡萄园属性，同时我们发现游说效应存在一些持续的偏差。我们还研究了来自历史和模拟的替代分类，这表明在过去一百年左右的时间里，地理标志的信息内容显着增加，
