We provide empirical evidence that the mixed results are due to the difficulty of identifying reliable variables to measure concentration and market power.\r\n\r\nDesign/methodology/approach\r\nUsing data from 3,943 banks operating in the European Union (EU)-15 between 2013 and 2020, we employ linear regression models on panel data. Banking market concentration is measured by the Herfindahl–Hirschman Index (HHI), and market power is estimated by the product-specific Lerner Indices for the loan and deposit market, respectively.\r\n\r\nFindings\r\nOur analysis reveals a significantly stability-decreasing impact of market concentration (HHI) and a significantly stability-increasing effect of market power (Lerner Indices). In addition, we provide evidence for a weak (or even absent) empirical relationship between the (non)structural measures, challenging the validity of the structure-conduct-performance (SCP) paradigm. Our baseline findings remain robust, especially when controlling for a likely reverse causality.\r\n\r\nOriginality/value\r\nOur results suggest that the HHI may reflect other factors beyond market power that influence banking stability. Thus, banking supervisors and competition authorities should investigate market concentration and market power simultaneously while considering their joint impact on banking stability.","lang":"eng"}]},{"publication_status":"draft","jel":["D43","L13","L42"],"citation":{"ama":"Endres-Fröhlich AE, Hehenkamp B, Heinzel J. <i>The Impact of Product Differentiation on Retail Bundling in a Vertical Market</i>.","ieee":"A.

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.","lang":"eng"}],"user_id":"37339","department":[{"_id":"280"},{"_id":"475"}],"project":[{"name":"SFB 901: SFB 901","_id":"1"},{"name":"SFB 901 - A: SFB 901 - Project Area A","_id":"2"},{"name":"SFB 901 - A3: SFB 901 - Subproject A3","_id":"7"}],"_id":"44091","language":[{"iso":"eng"}],"keyword":["Retail bundling","upstream market power","double marginalization","product differentiation"]}]
