Abstract (eng)
This thesis addresses the question of whether expert ratings have an influence on fine wine prices. For this reason, a selection of renowned critics in the wine industry has been made. Subsequently a selection of the rated wines was carried out and carefully reduced according to appropriate arguments to make data comparable. A regression discontinuity in time model was applied and interpreted visually as well as statistically. Further, a Wilcoxon test was conducted to check the results. The majority of the sampled wines shows that the rating has a significantly positive impact on the price, which is in line with previous literature.
