We construct product-specific residual Lerner Indices to measure market power in the loan and deposit market separately. Our results suggest that banks with higher loan and deposit market power securitize less, consistent with a reduced need for risk transfer and a reduced reliance on market-based funding. Various sensitivity analyses further show that these relationships vary across underlyings, issuance frequencies, and different time stages of securitization in Europe. Our findings contribute to the literature by disentangling loan and deposit market power as two further distinct determinants of securitization and thus, offer important insights regarding the ongoing policy debates on the consolidation of European banking markets and the revitalisation of the European securitization market.","lang":"eng"}],"_id":"65685","language":[{"iso":"eng"}],"ddc":["040"],"user_id":"51867","status":"public","year":"2026","title":"Securitization and Market Power – Evidence from European Banks","jel":["G21","G28"],"author":[{"first_name":"Sarah","last_name":"Herwald","full_name":"Herwald, Sarah","id":"51867"},{"last_name":"Uhde","first_name":"André","full_name":"Uhde, André","id":"36049"}],"date_updated":"2026-05-27T06:50:46Z","has_accepted_license":"1"},{"abstract":[{"lang":"eng","text":"This paper empirically examines the relationship between market power and Environmental, Social, and Governance (ESG) scores of banks in Europe and North America from 2010 to 2021, focusing separately on loan and deposit markets. Employing the Lerner Index as a non-structural measure of market power, our findings suggest that the impact of banking market power on ESG scores varies by region and the respective loan or deposit market. We find a negative effect of loan and deposit market power on ESG scores of European banks whereas the opposite effect can be observed for North American banks exhibiting loan market power. Further sensitivity analyses reveal that factors such as banks being Global Systemically Important (G-SIBs), and different ESG-related events like the Paris Agreement, the reemergence of the #MeToo movement and the COVID-19 pandemic may also explain the relationship between bank market power and ESG scores. Overall, our results underline that banking market power plays a pivotal role in enforcing ESG commitments in banking, offering key insights for policymakers, regulators, and banking stakeholders."}],"file":[{"date_created":"2026-07-14T07:50:01Z","creator":"simonevo","file_id":"66475","success":1,"content_type":"application/pdf","relation":"main_file","date_updated":"2026-07-14T07:50:01Z","file_name":"Voigt und Uhde (2026)_corr.pdf","file_size":849260,"access_level":"closed"}],"date_created":"2026-05-26T11:29:08Z","type":"working_paper","keyword":["Market Power","ESG scores","European and North American banking markets"],"department":[{"_id":"19"}],"title":"The impact of market power on banks' ESG scores - evidence from Europe and North America","year":"2026","author":[{"full_name":"Voigt, Simone","first_name":"Simone","last_name":"Voigt","id":"50109"},{"id":"36049","last_name":"Uhde","first_name":"André","full_name":"Uhde, André"}],"date_updated":"2026-07-14T07:50:16Z","publication_status":"draft","language":[{"iso":"eng"}],"file_date_updated":"2026-07-14T07:50:01Z","citation":{"ama":"Voigt S, Uhde A. <i>The Impact of Market Power on Banks’ ESG Scores - Evidence from Europe and North America</i>.","bibtex":"@book{Voigt_Uhde, title={The impact of market power on banks’ ESG scores - evidence from Europe and North America}, author={Voigt, Simone and Uhde, André} }","mla":"Voigt, Simone, and André Uhde. <i>The Impact of Market Power on Banks’ ESG Scores - Evidence from Europe and North America</i>.","chicago":"Voigt, Simone, and André Uhde. <i>The Impact of Market Power on Banks’ ESG Scores - Evidence from Europe and North America</i>, n.d.","short":"S.

The semiparametric \r\nvariants employ a multiplicative volatility decomposition into conditional and slowly varying \r\nunconditional components, where the latter is estimated via a data-driven local polynomial \r\nsmoother to accommodate non-stationarities commonly observed in financial time series. Based \r\non the revised Basel Committee framework for market-risk assessment, all models are capable \r\nof producing rolling one-day-ahead forecasts for Value at Risk (VaR) and Expected Shortfall \r\n(ES) under a wide range of symmetric and skewed innovation distributions. Their forecasting \r\naccuracy is examined using the regulatory traffic light tests for VaR and the recently developed \r\nES-specific traffic light procedure, complemented by the regulatory loss function. In addition, \r\nmodel selection incorporates both a recently proposed corrected firm-oriented loss function that \r\naccounts for opportunity costs and the Weighted Absolute Deviation (WAD) criterion. The \r\nempirical comparison demonstrates that (semiparametric) long memory GARCH models - \r\nparticularly those combining fractional dynamics with nonparametric scale adjustments - can \r\nserve as valuable alternatives to traditional parametric short memory models, offering more \r\nstable volatility estimates and improved tail-risk forecasts for practical risk management \r\napplications.","lang":"eng"}],"citation":{"mla":"Hanke, Dominik Christian, et al. <i>Application of Novel Exponential (Semi-)Parametric Short and Long  Memory GARCH Models under Regulatory Requirements of Basel III</i>. 2026.","bibtex":"@book{Hanke_Uhde_Feng_2026, title={Application of Novel Exponential (Semi-)Parametric Short and Long  Memory GARCH Models under Regulatory Requirements of Basel III}, author={Hanke, Dominik Christian and Uhde, André and Feng, Yuanhua}, year={2026} }","ama":"Hanke DC, Uhde A, Feng Y. <i>Application of Novel Exponential (Semi-)Parametric Short and Long  Memory GARCH Models under Regulatory Requirements of Basel III</i>.; 2026.","ieee":"D.

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"}]},{"user_id":"66731","_id":"45812","language":[{"iso":"eng"}],"date_updated":"2023-06-28T11:18:31Z","status":"public","title":"Interview Study on Strategy Options for Platform Operation in B2B Markets","year":"2023","author":[{"id":"45137","last_name":"Özcan","first_name":"Leon","full_name":"Özcan, Leon"},{"full_name":"Fichtler, Timm","first_name":"Timm","orcid":"https://orcid.org/0000-0001-6034-4399","last_name":"Fichtler","id":"66731"},{"full_name":"Kasten, Benjamin","first_name":"Benjamin","last_name":"Kasten"},{"id":"43136","orcid":"https://orcid.org/0000-0001-7992-6399","last_name":"Koldewey","first_name":"Christian","full_name":"Koldewey, Christian"},{"full_name":"Dumitrescu, Roman","last_name":"Dumitrescu","first_name":"Roman","id":"16190"}],"conference":{"location":"Ljubljana","name":"ISPIM Innovation Conference"},"keyword":["Digital Platform","Platform Strategy","Strategic Management","Platform Life Cycle","Interview Study","Business Model","Business-to-Business","Two-sided Market","Multi-sided Market"],"type":"conference","department":[{"_id":"563"}],"date_created":"2023-06-28T11:18:12Z","citation":{"apa":"Özcan, L., Fichtler, T., Kasten, B., Koldewey, C., &#38; Dumitrescu, R.

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"}],"project":[{"_id":"1","name":"SFB 901: SFB 901"},{"_id":"2","name":"SFB 901 - A: SFB 901 - Project Area A"},{"name":"SFB 901 - A3: SFB 901 - Subproject A3","_id":"7"}],"page":"43","_id":"44091","language":[{"iso":"eng"}],"user_id":"37339","status":"public","title":"The Impact of Product Differentiation on Retail Bundling in a Vertical Market","year":"2022","jel":["D43","L13","L42"],"author":[{"id":"48794","full_name":"Endres-Fröhlich, Angelika Elfriede","first_name":"Angelika Elfriede","last_name":"Endres-Fröhlich"},{"id":"37339","first_name":"Burkhard","last_name":"Hehenkamp","full_name":"Hehenkamp, Burkhard"},{"full_name":"Heinzel, Joachim","first_name":"Joachim","last_name":"Heinzel"}],"date_updated":"2023-04-20T17:15:48Z","publication_status":"draft"},{"issue":"2","publication":"Scandinavian Journal of Economics","abstract":[{"text":"We analyse the two-dimensional Nash bargaining solution (NBS) by deploying\r\nthe standard labour market negotiations model of McDonald and Solow (1981).\r\nWe show that the two-dimensional bargaining problem can be decomposed into two\r\none-dimensional problems, such that the two solutions together replicate the solution\r\nof the two-dimensional problem if the NBS is applied.

As a result, more and more companies are trying to participate in the platform economy. However, the successful development and operation of a digital platform is associated with significant challenges, which leads to 85% of all platforms failing. A core challenge is the dynamic nature of the platform economy, with varying strategic objectives at different stages in the platform lifecycle. Platform operators must continuously monitor platform progress and adjust their strategy.\r\nUtilizing action research in the real-world platform project AI Marketplace, we developed a lifecycle-oriented performance management approach for digital platforms in B2B markets. It enables platform operators to reflect on their position in the platform lifecycle, derive relevant strategic objectives, and monitor them with suitable key performance indicators. Hence, allowing them to secure the long-term success of their platform business.","lang":"eng"}],"publication":"The Role of Innovation: Past, Present, Future","user_id":"1112","ddc":["600"],"editor":[{"full_name":"Bitran, Iain","first_name":"Iain","last_name":"Bitran"},{"first_name":"Leandro","last_name":"Bitetti","full_name":"Bitetti, Leandro"},{"full_name":" Conn, Steffen","first_name":"Steffen","last_name":" Conn"},{"last_name":"Fishburn","first_name":"Jessica","full_name":"Fishburn, Jessica"},{"last_name":"Huizingh","first_name":"Eelko ","full_name":"Huizingh, Eelko "},{"last_name":"Torkkeli","first_name":"Marko","full_name":"Torkkeli, Marko"},{"first_name":"Jialei","last_name":"Yang","full_name":"Yang, Jialei"}],"_id":"33997","has_accepted_license":"1","status":"public","conference":{"start_date":"2022-11-28","name":"ISPIM Connects Athens","location":"Athens","end_date":"2022-11-30"},"place":"Athens","file_date_updated":"2022-11-04T07:30:29Z","citation":{"bibtex":"@inproceedings{Özcan_Kirchberg_Koldewey_Dumitrescu_2022, place={Athens}, title={Performance Management Approach for Digital Platforms in B2B Markets}, booktitle={The Role of Innovation: Past, Present, Future}, author={Özcan, Leon and Kirchberg, Lisa Irene and Koldewey, Christian and Dumitrescu, Roman}, editor={Bitran, Iain and Bitetti, Leandro and  Conn, Steffen and Fishburn, Jessica and Huizingh, Eelko  and Torkkeli, Marko and Yang, Jialei}, year={2022} }","chicago":"Özcan, Leon, Lisa Irene Kirchberg, Christian Koldewey, and Roman Dumitrescu. “Performance Management Approach for Digital Platforms in B2B Markets.” In <i>The Role of Innovation: Past, Present, Future</i>, edited by Iain Bitran, Leandro Bitetti, Steffen  Conn, Jessica Fishburn, Eelko  Huizingh, Marko Torkkeli, and Jialei Yang.

We further find that IFRS is associated with an increase (decrease) in industry sales concentration (competition), consistent with large public firms increasing market share.

Asymmetries between intermediaries may arise due to distinct product qualities as well as by reasons of different production technologies. The intermediaries compete on the output market by choosing production quantities sequentially and for the supplies of a monopolistic input supplier on the input market. It turns out that there exist differences in product quality and productivities such that an intermediary being the Stackelberg leader has no incentive to procure inputs, whereas in the role of the Stackelberg follower will participate in the market. Moreover, we find that given an intermediary is more competitive, his equilibrium output quantity is higher when being the leader than when being the follower. Interestingly, if the intermediary is less competitive and goods are complements, there may exist asymmetries such that an intermediary being in the position of the Stackelberg follower offers higher output quantities in equilibrium than when being in the position of the Stackelberg leader.","lang":"eng"}],"_id":"2570","publisher":"CIE Working Paper Series, Paderborn University","volume":98,"ddc":["040"],"user_id":"65453","status":"public","has_accepted_license":"1","citation":{"bibtex":"@book{Manegold_2016, series={Working Papers CIE}, title={Stackelberg Competition among Intermediaries in a Differentiated Duopoly with Product Innovation}, volume={98}, publisher={CIE Working Paper Series, Paderborn University}, author={Manegold, Jochen}, year={2016}, collection={Working Papers CIE} }","ama":"Manegold J. <i>Stackelberg Competition among Intermediaries in a Differentiated Duopoly with Product Innovation</i>.

While prior research shows promising potential for this model, it has never been tested on a large scale dataset. Thus, guided by economic theory, this paper is the first to design a large-scale applicable implementation on around 30,000 technology firm quarter observations from 1992 to 2009 for the US to assess this model. Evaluating the feasibility and performance of the Schwartz-Moon model reveals that it is comparably accurate to the traditional sales multiple with key advantages in valuing small and non-listed firms. Most importantly, however, the model is able to indicate severe market over- or undervaluation from a fundamental perspective. We demonstrate that a trading strategy based on our implementation has significant investment value. Consequently, the model seems suitable for detecting misvaluations as the dot-com bubble.","lang":"eng"}],"extern":"1","issue":"9","publication":"Journal of Business Economics (VHB-JOURQUAL 4 Ranking B)","department":[{"_id":"275"}],"keyword":["Schwartz-Moon model","Market mispricing","Empirical test","Company valuation","Trading strategy"],"type":"journal_article","date_created":"2018-10-31T11:31:56Z","jel":["G11","G12","G17","G33"],"status":"public","volume":83,"user_id":"115848","publisher":"Springer","_id":"5192","page":"947-984","quality_controlled":"1","citation":{"ama":"Klobucnik J, Sievers S.

With increasing storage demands and emerging storage services the question how to schedule storage jobs becomes more and more interesting. Since such scheduling problems are often in the class NP-complete an exact computation is not feasible in practice. On the other hand an approximation to the optimal solution can easily be found by means of using heuristics. The problem with this attempt is that the suggested solution may not be exactly optimal and is thus less satisfying. Considering the two above mentioned solution approaches one can clearly find a trade-off between the optimality of the solution and the efficiency to get to a solution at all. This work proposes to apply and combine heuristics in optimization to gain from both of their benefits while reducing the problematic aspects. Following this method it is assumed to get closer to the optimal solution in a shorter time compared to a full optimization.","lang":"eng"}],"publication":"18th European Conference on Information Systems (ECIS 2010)"}]
