Natural Endowments, Production Technologies and the Quality of Wines in Bordeaux. Does Terroir Matter?
利用1980-1992年拍卖价格和专家评分，发现生产技术对葡萄酒品质的影响远大于自然禀赋（如土壤、朝向），后者作用微乎其微。
We study whether quality assessments made by wine experts and by consumers (based on prices obtained at auction between 1980 and 1992) can be explained by variables describing endowments (land characteristics, exposures of vineyards) and technologies (from grape varieties and picking, to bottled wines). However, since technological choices are likely to depend on endowments, the effects can only be identified using an instrumental variables approach. We show that technological choices affect quality much more than natural endowments, the effect of which is negligible.
