However, methods and techniques for the monetary valuation of brands are still under-researched. Hence, the objective of this study is to evaluate the utility of explanatory statistical models and machine learning approaches for explaining and predicting brand value. Drawing upon the case of the most valuable English football brands during the 2016/17 to 2020/21 seasons, we demonstrate how to operationalize Aaker's (1991) theoretical brand equity framework to collect meaningful qualitative and quantitative feature sets. Our explanatory models can explain up to 77% of the variation in brand valuations across all clubs and seasons, while our predictive approach can predict out-of-sample observations with a mean absolute percentage error (MAPE) of 14%. Future research can build upon our results to develop domain-specific brand valuation methods while enabling managers to make better-informed investment decisions."}]},{"_id":"42948","language":[{"iso":"ger"}],"user_id":"37953","status":"public","title":"Der Marktplatz von Amazon - Eine wettbewerbspolitische Analyse","year":"2022","author":[{"full_name":"Kuzuoglu, Muhammed Numan","first_name":"Muhammed Numan","last_name":"Kuzuoglu"}],"date_updated":"2023-03-10T10:38:15Z","date_created":"2023-03-10T10:38:02Z","type":"bachelorsthesis","department":[{"_id":"280"}],"supervisor":[{"last_name":"Hehenkamp","first_name":"Burkhard","full_name":"Hehenkamp, Burkhard","id":"37339"}],"citation":{"chicago":"Kuzuoglu, Muhammed Numan. <i>Der Marktplatz von Amazon - Eine wettbewerbspolitische Analyse</i>, 2022.","short":"M.N.

Two monopolistic manufacturers each produce a differentiated good. One sells it to both retailers, while the other only supplies a single retailer. Retailers compete in prices. Retail bundling is profitable when the goods are close substitutes. Only then is competition so intense that the retailer uses bundling to relax competition both within and across product markets, despite an aggravation of the double marginalization problem. Our asymmetric market structure arises endogenously for the case of close substitutes. In this case, bundling reduces social welfare."}],"project":[{"_id":"1","name":"SFB 901: SFB 901"},{"_id":"2","name":"SFB 901 - A: SFB 901 - Project Area A"},{"_id":"7","name":"SFB 901 - A3: SFB 901 - Subproject A3"}],"citation":{"apa":"Endres-Fröhlich, A.
