The international trade impacts of Geographical Indications: Hype or hope?
通过元分析梳理现有研究，发现地理标志对国际贸易有积极影响，且结论在控制研究方法差异后依然稳健。
The European Geographical Indication quality scheme (GI) is supposed to enhance local expertise and support spatially-embedded products worldwide. Currently, the effect of GIs on trade is controversial. In general, GIs seem to support international trade, but the literature has not reached a consensus. We aim to identify and summarise heterogeneous results from existing research using a meta-analysis approach. Our results confirm that GIs positively affect trade, even after controlling for the effects of various characteristics of the studies, the methodology adopted, and publication impacts.
