These include the vulnerability of borrowers, increased credit risks and the need to adapt to the changing climate. Using a novel microcredit data set, we first study the prevalence of climatic hazards and vulnerabilities in the portfolios of MFIs across Latin America and the Caribbean as well as sub-Saharan Africa. We find evidence of microborrower vulnerability to climatic hazards and associated heightened credit risk. We then explore ecosystem-based adaptation (EbA) as a potential strategic complement to inclusive finance in aiding adaptation. Our analysis finds widespread autonomous implementation of EbA by agricultural microborrowers. While EbA measures appear to negatively moderate the association between climatic hazards and microborrower vulnerabilities, we do not find them to be directly associated with lower vulnerabilities. Furthermore, lenders do not appear to increase financing of adaptation in portfolios with greater exposure to climatic hazards. The findings suggest a need to enhance the effectiveness of adaptive actions and further potential to expand the financing of EbA by MFIs. article 2025 2 18 1099-0836,0964-4733 10.1002/bse.4178 Business Strategy and the Environment 34 Wiley 4409-4435 https://epub.uni-regensburg.de/id/eprint/75042 Gregor Dorfleitner Davide Forcella Andreas Gerckens This paper shows that ESG scores capture a company’s greenwashing behavior. Greenwashing accusations are most prevalent among large companies with high ESG scores. We empirically employ a novel theoretical model that distinguishes between the communication of a company’s environmental efforts (apparent environmental performance) and its actual environmental impact (real environmental performance). The correlation of the apparent (real) environmental performance with ESG scores is significantly positive (negative). Therefore, ESG scores are unsuitable for measuring real environmental impact. Thus, investors focusing on high ESG-rated companies may unknowingly increase their greenwashing risk exposure, and academics may use misleading information to assess greenwashing risk. article 2025 1 07 1544-6131,1544-6123 10.1016/j.frl.2024.106710 Finance Research Letters Elsevier https://epub.uni-regensburg.de/id/eprint/74584 Manuel Kathan Sebastian Utz Gregor Dorfleitner Jens Eckberg Lea Chmel Higher education institutions (HEIs) contribute to society and the planet by producing future implementers of sustainability, addressing the climate crisis, and promoting nature-positive actions through research. Despite their positive contributions, given the total number of HEIs globally, and the scale at which they operate, their environmental footprint negatively impacts the environment. The Millennium Development Goals (MDGs) and the Sustainable Development Goals (SDGs) alone were insufficient to integrate sustainability in HEIs without initiatives by universities and non-profits since the 1970s. An analysis of the past and current state of sustainability integration in HEIs reveals a disparity in sustainability reporting and rankings between the Global North and Global South. Furthermore, the number of universities participating in sustainability reporting and rankings is significantly low. Sustainability in HEIs must extend beyond curriculum and research, requiring standardized reporting frameworks, adequate budgets for enforcing sustainability, better impact assessment metrics, and support for the Global South. article 2025 Cleaner Environmental Systems Elsevier https://epub.uni-regensburg.de/id/eprint/76637 Samhita Ankareddy Gregor Dorfleitner Lin Zhang Yong Sik Ok Loss of biodiversity and natural degradation are vital issues that have significant impacts on society and economy. Businesses, investors, and regulators have focused on corporate efforts to support biodiversity and nature-positive activities. This review provides a comprehensive overview of the importance of biodiversity for businesses, its materiality, and the roles of mandatory and nonmandatory regulations in corporate environmental reporting and sustainability disclosure frameworks. It also discusses descriptive information on the evolution of sustainability frameworks by comparing the most prominent sustainability frameworks, with a key focus on the materiality approach and biodiversity-related disclosure recommendations. Furthermore, we provide recommendations for more holistic approaches to improve future sustainability frameworks focusing on the impact of biodiversity. Additionally, we demonstrate the necessity for greater focus on the decision-making paradigm. Further research to measure the impact of biodiversity and innovative trends in sustainability reporting is required to better reflect nature-positive outcomes in corporate sector businesses. article 2024 9 17 10.3390/su16188110 Sustainability 16 MDPI 8110 18 https://epub.uni-regensburg.de/id/eprint/59219 Maheshika Senanayake Iman Harymawan Gregor Dorfleitner Seungsoo Lee Jay Hyuk Rhee Yong Sik Ok Based on an international data set that comprises over 6,100 companies located in 44 countries in the years 2002–2018, this paper analyzes the relation between corporate scandals and board structures besides further firm-related, political, nation-level economic, and cultural variables. We identify board structure variables that are positively associated with a firm’s corporate scandals, namely high CSR efforts and busy board members. There are also variables that are negatively associated with this kind of behavior, namely qualified and skilled boards. No clear evidence can be determined from a board’s gender diversity, independent board members, and board size. article 2024 8 21 2366-6153,0341-2687 10.1007/s41471-024-00192-4 Schmalenbach Journal of Business Research 76 Springer 433-461 https://epub.uni-regensburg.de/id/eprint/59218 Gregor Dorfleitner Christian Kreuzer This article examines whether mobile money adoption contributes to women’s economic empowerment, and considers the mediating effect of financial management behavior. Cross-sectional data analysis is conducted utilizing a sample of women in seven countries across South Asia and Sub-Saharan Africa. We also investigate whether these effects vary between rural and urban areas. Three measures of mobile money adoption are considered to reflect the process of engaging in mobile money services. We find supportive evidence for the impact of mobile money adoption on women’s economic empowerment and the influencing mechanism of financial management behavior for the whole sample and the rural sub-sample. Moreover, the results are consistent for three alternative measures of mobile money adoption. Our findings suggest that mobile money can be harnessed to promote women’s economic empowerment; however, the impact appears to be greater if women are equipped with proper financial management skills. article 2024 7 08 1863-6691,1863-6683 10.1007/s11846-022-00564-2 Review of Managerial Science 18 Springer 1807-1836 https://epub.uni-regensburg.de/id/eprint/52603 Gregor Dorfleitner Quynh Anh Nguyen article 2024 2366-6153,0341-2687 Schmalenbach Journal of Business Research 76 Springer 197-244 https://epub.uni-regensburg.de/id/eprint/58124 Gregor Dorfleitner Rongxin Zhang This paper proposes a conceptual framework to determine a greenwashing indicator on firm level, based on five pillars of information that capture the key drivers of greenwashing: soft ESG data, textual self-representation, green marketing expenses, green virtue for the apparent green performance, and hard ESG data as a measure of the real green performance. The proposed framework is built on a literature review of greenwashing typology and drivers and can be applied to a broad set of firms at the same time, while most existing approaches are built on a detailed investigation of individual cases. The greenwashing indicator in our framework is based on the difference between real and apparent green performance. This approach allows the implicit calculation of the real green performance using the concept of a firm misconduct factor that helps to identify the greenwashing indicator without knowledge of the real (and often hard to measure) green performance of a firm. article 2024 1863-6683,1863-6691 10.1007/s11846-023-00718-w Review of Managerial Science 18 SPRINGER HEIDELBERG

We study the content of 276 privacy statements respectively before and after the GDPR became binding. Using text analysis methods, we find that the readability of the privacy statements has decreased. The texts of privacy statements have become longer and use more standardized language, resulting in worse user comprehension. This calls into question whether the GDPR has achieved its original goal-the protection of natural persons regarding the transparent processing of personal data. We also link the content of the privacy statements to FinTech-specific determinants. Before the GDPR became binding, more external investors and a higher legal capital were related to a higher quantity of data processed and more transparency, but not thereafter. Finally, we document mimicking behavior among FinTech industry peers with regard to the data processed and transparency. article 2023 7 20 1019-6781,1422-8890 10.1007/s12525-023-00622-x Electronic Markets 33 SPRINGER HEIDELBERG

We hand-collected data on 173 real estate tokens in the USA between 2019 and 2021 and trace back 238,433 blockchain transactions. We find that tokens provide broad real estate ownership to many small investors through digital fractional ownership and low entry barriers, while investors do not yet hold well-diversified real estate token portfolios. We analyze the determinants of the success of security token offerings (STOs), secondary market trading, and daily aggregated capital flows. In addition to some property-specific determinants, we find that crypto-market-specific determinants, such as transaction costs and the related sentiment, are relevant both to the STO and capital flows.& COPY; 2023 The Author(s).

This report provides a hand-collected market overview of the FinTech market in Germany, as well as an application case in terms of volume estimates for the financing and asset management segments through December 2021. The data includes various verified characteristics of 978 unique companies that can be classified under the financial technology sector and operate in Germany. Each observation represents a company with 24 variables, including name, address, legal form, founders with corresponding LinkedIn accounts, registration number or company ID, assignment to FinTech segments and sub-segments, banking cooperation, URL address, local court, former name, operating status. We provide the description of the variables as well as a taxonomy to categorize FinTechs. The dataset contains both established companies and startups and presents valuable information for researchers, practitioners and also regulators. article 2023 1865-5734,2199-1235 10.3790/ccm.56.1.103 Credit and Capital Markets 56 Duncker und Humblot 103-118 1 https://epub.uni-regensburg.de/id/eprint/54330 Gregor Dorfleitner Julia Kreppmeier Ralf Laschinger We examine investor behavior on a leading peer-to-business lending platform and identify an investment mistake that we refer to as default shock bias. First, we find that investors stop investing in new loans and cease diversifying their portfolio after experiencing a loan default. The default shock significantly worsens the risk–return profile of investors’ loan portfolios. The defaults investors experience are often not beyond what would have been expected from the information that was provided by the platform ex ante. Second, investment experience on the platform is related to better investment decisions in general, but it does not reduce the default shock bias. These findings have important implications not only for the behavioral finance literature but also more generally for new forms of Internet-based finance. article 2023 1863-6691,1863-6683 10.1007/s11846-022-00544-6 Review of Managerial Science 17 Springer 1037-1073 https://epub.uni-regensburg.de/id/eprint/52289 Gregor Dorfleitner Lars Hornuf Martina Weber article 2022 9 2331-2947,1526-5943 Journal of Risk Finance 23 Emerald 85-120 1 https://epub.uni-regensburg.de/id/eprint/47920 Gregor Dorfleitner Johannes Grebler article 2022 9 1758-8855,0967-5426 10.1108/JAAR-02-2021-0041 Journal of Applied Accounting Research 23 Emerald 454-479 https://epub.uni-regensburg.de/id/eprint/47918 Gregor Dorfleitner Davide Forcella Quynh-Anh Nguyen Social trading platforms are considered to be amongst the major innovations in online trading. The purpose of this article is to analyze the trading activity of traders on social trading networks by taking a behavioral approach. We investigate the factors that influence the irrational part of trading activity derived from the key characteristics of these platforms, i.e. those dealing with social interaction. Our investigation utilizes an extensive set of trading data from two major platforms in Germany to study the trading behavior. We apply a fixed effects two-stage least squares approach to quantify the relationship between trading ctivity and performance and define overconfidence as the part of trading activity that is irrationally motivated and results in negative returns. Our results provide evidence for the negative relationship between overconfidence and return on social trading platforms. The article finds that the number of followers and some platform-specific features significantly affect the trading behavior of the traders. We contribute to literature by exploring how the novel social interaction characteristics of online trading impact trading activity by giving rise to a new dimension of overconfidence. In addition, we evidence that the different frameworks of the platforms motivate heterogenous behavioral responses by the signalers. Finally, we refine existing studies by applying a distinct methodology for modeling overconfidence. article 2022 9 1526-5943,2331-2947 Journal of Risk Finance 23 Emerald 32-54 1 https://epub.uni-regensburg.de/id/eprint/47919 Gregor Dorfleitner Isabel Scheckenbach We extend risk-value models for valuing streams of risky cash flows by establishing the well-known concept of terminal value in this context. For a constant growth assumption we are able to derive upper and lower bounds for the terminal value in the case of a translation-invariant and in the case of a position-invariant risk measure. For both cases we also obtain an exact formula under a special growth assumption for the future cash flows. Furthermore, we provide results on the applicability of the general findings for the case that the log-return of the risky investment follows a Brownian motion. article 2022 0254-5330,1572-9338 10.1007/s10479-020-03644-2 Annals of operations research 313 Springer

In particular, we empirically analyze how an infinite investment horizon and valuable outside options affect risk taking behavior. We find that traders choose the absolute and relative risk of the trading strategy depending on the proximity to the high-water mark (HWM), which represents a series of remuneration options on the assets under management. As a consequence, we observe more risk mitigating behavior the closer the HWM comes. Next, we show that the traders behave strategically and make their risk decisions based on their overall portfolio payoff. Finally, we find that social status indicators such as rankings and communication abilities significantly affect the risk taking behavior. (c) 2021 Board of Trustees of the University of Illinois.

To estimate a green-pricing effect, we determine the 'green bond premium' as the difference between the yields of matched conventional and green-labeled bonds. On a cross-sectional average, green bonds experience a statistically significant positive premium. This premium increases with external greenness evaluations, i.e., investors accept premiums of up to 5 basis points for bonds with a substantial environmental agenda. This external validation effect, which is strongest for bonds that are rated dark-green, may offset not incurring information costs, as this effect decreases with increasing age of bonds. article 2021 4 01 1863-6683,1863-6691 10.1007/s11846-021-00458-9 Review of Managerial Science 16 SPRINGER HEIDELBERG

As measurements for corporate social irresponsibility as well as corporate social responsibility activities, it is shown that US mutual funds exhibit controversies and ESG persistence in the short and longer-term. When examining the relationship between controversies and ESG scores in comparison with management fees, it becomes apparent that higher-paid managers achieve better results regarding controversies scoring but worse results regarding ESG scoring, compared to lower-paid managers. article 2021 1544-6123,1544-6131 10.1016/j.frl.2021.101990 Finance Research Letters 43 ACADEMIC PRESS INC ELSEVIER SCIENCE

Arnold Benedikt Booker Gregor Dorfleitner Michaela R?he We provide evidence of the exogenous impact of environmental and social performance components on credit ratings in North America, Europe, and Asia. In particular, the product innovation dimension is clearly identified as being the dominating driver of credit ratings within the environmental performance in every subsample region. In the social performance dimension, the extent of diversity is a main driver for firms in North America and Europe, but due to cultural reasons, not in Asia. Our results show that the risk mitigation view holds for all significant corporate social or environmental performance variables, but the magnitude of impact differs regionally. article 2020 12 23 2198-2627,2198-3402 10.1007/s40685-020-00127-9 Business Research 13 Springer 1343-1415 3 https://epub.uni-regensburg.de/id/eprint/46347 Gregor Dorfleitner Johannes Grebler article 2020 2199-4455,0018-974X ifo Schnelldienst 73 ifo Institut 33-40 8 https://epub.uni-regensburg.de/id/eprint/43629 Gregor Dorfleitner Lars Hornuf Lena Wannenmacher Based on an extensive international dataset containing Thomson Reuters environmental, social and corporate governance (ESG) rating, as well as Thomson Reuters newest controversies and combined score of an average of 2500 companies in the years 2002–2018, this article contributes to the existing discourse of the relationship between corporate social performance and corporate financial performance (CFP) by examining the Fama and French (J Financ Econ 116(1):1–22, 2015) five-factor risk-adjusted performance of positive screened best and worst portfolios, based on a 10% cutoff, respectively, for equally, value- and rank-weighted strategies in the European, US and global market. Furthermore, the controversies score allows us to examine the mid-to-long-term effects of scandals on the CFP without having to rely on the event study methodology. Even though a value-weighted strategy does not show any significant abnormal returns, we examined a significant outperformance for equally weighted worst ESG portfolios and best controversies strategies. These results strongly indicate that this is, on the one hand, driven by low-rated smaller companies (“small sinners”) and clean-coated firms with regard to controversies (“silent saints”) on the other hand. The findings hold for several robustness checks such as adjusting the cutoff rates or splitting the dataset across time. article 2020 1470-8272,1479-179X 10.1057/s41260-020-00178-x Journal of Asset Management 21 Springer 393-412 https://epub.uni-regensburg.de/id/eprint/43486 Gregor Dorfleitner Christian Kreuzer Christian Sparrer article 2020 2199-1235,2199-1227 10.3790/ccm.53.4.427 Credit and Capital Markets 53 Duncker & Humblot 427-460 4 https://epub.uni-regensburg.de/id/eprint/43669 Gregor Dorfleitner Davide Forcella Quynh-Anh Nguyen We quantify the extent to which the quality of credit rating predictions improves by integrating measures of corporate social performance (CSP) in an established credit risk model. Our analysis provides comprehensive evidence of the comparative informational advantage of considering CSP in predicting credit ratings of North American and European firms. In the North American sample, both environmental and social performance have an explanatory impact. The out-of-sample prediction quality improves by more than 0.8%. By contrast, only social performance increases the explanatory power in the European sample; environmental performance does not. Overall, we show that CSP is a relevant variable for predicting credit ratings. In general, our findings support the risk mitigation view of CSP, indicating that firms with high CSP are less risky and thus have better credit ratings. However, the quality of the relationship depends on the socioeconomic and cultural environment as well, as can be seen from the differing results in North America and Europe. article 2020 1465-1211,1755-2842 10.21314/JOR.2020.437 Journal of Risk 22 INCISIVE MEDIA

Using a worldwide data set on 999 MFIs and employing a probit regression, we find a positive relationship between the financial expenses of an institution and MFS adoption. Our results also show that the share of deposits is positively related to the probability of offering MFS. Moreover, larger institutions and MFIs of the bank type are more likely to adopt mobile technology in providing financial services. Furthermore, the depth of outreach is weakly positively related to the provision of MFS, suggesting that the social mission of MFIs is not impaired by the provision of MFS. article 2019 1544-6123,1544-6131 10.1016/j.frl.2018.12.002 Finance Research Letters 31 ACADEMIC PRESS INC ELSEVIER SCIENCE

By applying standard multi-factor performance evaluation models, and the new five-factor model of Fama and French (2015), we observe that the most valuable brands outperform the market during the overall period from 2000 to June 2018 as well as during different market conditions. However, the extent of the outperformance is much larger during bear than during normal periods, suggesting that the most valuable brands tend to perform better during weak financial market periods. Moreover, we find that the outperformance is driven by only a few industries, e.g., business services, technology and retail.

We use a novel classification of these activities into nine areas, each belonging to one of the standard environment, social, and governance (ESG) dimensions. Using cross-sectional return regressions and buy-and-hold abnormal returns, we find that firms with strong CSR significantly outperform firms with weak CSR in the mid and long run in certain areas. Firm returns increase up to 3.8% with respect to a one-standard-deviation increase of the CSR rating. In a two-stage least squares (2SLS) approach we verify that the main economic channel for the appreciation of strong CSR stocks is unexpected additional cash flows. The results are relevant for assessing the efficiency of CSR, and have broader implications for asset managers who can expect abnormal returns by investing in firms that exhibit a high CSR in the respective scores and holding the stocks for a longer period. article 2018 2043-0809,2043-0795 Journal of Sustainable Finance and Investment 8 Taylor & Francis 132-157 https://epub.uni-regensburg.de/id/eprint/36310 Gregor Dorfleitner Sebastian Utz Maximilian Wimmer article 2018 1618-7601,1618-7598 European Journal of Health Economics 19 Springer Verlag 585-594 4 https://epub.uni-regensburg.de/id/eprint/35689 Gregor Dorfleitner Felix R??le We analyze the returns of traders, i.e. signal providers, on social trading platforms and of investors following these traders by utilizing differently sophisticated investment strategies. It becomes evident that simply investing in those traders with the highest accumulated returns leads to high losses, while taking the Sharpe ratio into account improves the achieved returns. Positive returns, however, are only possible for sophisticated strategies that consider information on the risk of the signal providers' portfolios. Moreover, no strategy reveals a positive abnormal return after transaction costs in the sense of a Carhart four-factor model. Further, we analyze predictors of the weekly returns of the signal providers in a panel set-up. We find that highly active trading behavior is negatively related with the returns, while there is no wisdom-of-the-crowd effect, in the sense of a positive relationship of the number of followers or invested capital with the returns. article 2018 Quarterly Review of Economics and Finance 70 Elsevier 160-171 https://epub.uni-regensburg.de/id/eprint/37172 Gregor Dorfleitner Lukas Fischer Carina Lung Philipp Willmertinger Nico Stang Natalie Dietrich article 2018 1755-2842 (online),1465-1211 (print) Journal of Risk 20 Incisive Media 1-27 3 https://epub.uni-regensburg.de/id/eprint/35032 Gregor Dorfleitner Werner Glei?ner article 2017 2 17 1062-9769 (online),1062-9769 (print) Quarterly Review of Economics and Finance 63 Elsevier 89-100 https://epub.uni-regensburg.de/id/eprint/33289 Gregor Dorfleitner Susann Just-Marx Christopher Priberny article 2017 Journal of Asset Management 18 Palgrave Macmillan 81-98 2 https://epub.uni-regensburg.de/id/eprint/34041 Gregor Dorfleitner Mai Nguyen book 2017 978-3-319-54665-0 (Print), 978-3-319-54666-7 (Online) 10.1007/978-3-319-54666-7 Springer

In this paper, we present first empirical evidence concerning the question whether the risk of payment difficulties is appropriately reflected in the pricing variables. To this end, we investigate predictors of default of online invoice trading platforms. We analyze both the probability of default and the loss rate and find that the interest rate, the duration and the percentage funded have good predictive power. Furthermore, we show that the pricing mechanism (auction vs. fixed prices) helps to explain defaults on online invoice trading platforms. (C) 2017 Elsevier B.V.

In this study, we analyze the access of MFIs to debt capital from microfinance investment vehicles (MIVs). Using a data set on over 5000 MIV transactions, we examine the link between an MFI’s access to MIV funding and its maturity and performance. We identify a positive relation between debt capital from MIVs and the maturity of MFIs. Furthermore, MFIs with a solid financial performance in terms of portfolio quality exhibit better access. Our findings also suggest that MFIs maintaining their social mission experience easier access to funding from MIVs. article 2017 1062-9769 (online),1062-9769 (print) 10.1016/j.qref.2016.06.005 Quarterly Review of Economics and Finance 65 Elsevier 1-15 https://epub.uni-regensburg.de/id/eprint/33947 Gregor Dorfleitner Michaela R?he Noémie Renier We empirically study social failures of microfinance institutions (MFIs). Besides various measures for the financial performance and outreach, we consider the relationship between several institutional variables and social failure. Regarding the relationship with the financial performance, we identify MFIs with good portfolio quality as being less prone to social failure. Also, MFIs with better measures for the quality of outreach appear to be less likely to fail socially. Finally, MFIs with a higher fraction of donations and regulated institutions exhibit a lower probability of social failure, while fast growing MFIs appear to show a positive correlation.

Soft factors such as orthography, the share of non-mandatory information items provided and the mentioning of certain social keywords are derived from the loan applications. We find that soft factors do have a significant influence on the funding probability on the less restrictive of both platforms, which even accepts applications without credit scores. This platform shows a better risk-return profile.

The study is based on primary data collected in a survey using an online questionnaire. We apply tests for continuous and categorical data and (ordered) logit models. In a multivariate analysis that investigates determinants of socially responsible investing, we find little influence of the demographic factors gender and investment volume and none of educational level. Furthermore, we show that the regions investors allocate their money to are significant as well as the preference towards the order of return, risk and liquidity. Moreover, there seems to be a gap between supply and demand of socially responsible investments. Additionally, there are indications that a very important inducement for socially responsible investing is the expectation of high financial performance. This study broadens the scope of the literature by providing novel empirical evidence for the German-speaking market. article 2014 Qualitative Research in Financial Markets 6 118-156 2 https://epub.uni-regensburg.de/id/eprint/25957 Gregor Dorfleitner Sebastian Utz article 2014 1 1863-6683 (Print),1863-6691 (Online) Review of Managerial Science 8 Springer 89-119 1 https://epub.uni-regensburg.de/id/eprint/26573 Gregor Dorfleitner Hilger Jahnes High microcredit interest rates cause fierce debates among practitioners, scholars and even the general public. To objectify these discussions this article investigates determinants of microcredit interest rates by using a worldwide data set of 712 microfinance institutions. We examine how cost factors, gender, regulation, lending methodology, and organizational type affect microcredit interest rates. Controlling for other microfinance- and country-specific factors, we identify the operating expenses as the main factor influencing microcredit interest rates. Furthermore, our findings show that microfinance institutions tend to subsidize interest rates charged with income from investments not related to their lending activities. article 2013 10 01 10.1080/09603107.2013.839860 Applied Financial Economics 23 Taylor & Francis 1579-1597 20 https://epub.uni-regensburg.de/id/eprint/28460 Gregor Dorfleitner Michaela Leidl Christopher Priberny Jacob von Mosch We develop a quantitative model for structured microfinance instruments, which are regarded as an important means for refinancing microfinance institutions. The quantitative credit risk model presented takes into account the peculiarities of microfinance institutions and can be used for pricing purposes and analyzing the risk inherence in different tranches of a structured microfinance investment vehicle. Additionally, we introduce an innovative pricing methodology that abstains from using the martingale probability measure. This approach is more appropriate for illiquid securitized debt of microfinance institutions. In a realistic application we check the robustness and demonstrate the advantages of the model presented. article 2013 2 28 10.1016/j.qref.2012.10.005 Quarterly Review of Economics and Finance 53 Elsevier 12-22 1 https://epub.uni-regensburg.de/id/eprint/13157 Gregor Dorfleitner Christopher Priberny We study the perception of risks in the funding of microfinance institutions.

The approach applied in our analysis has high informational content as it differentiates between the sources of the diversification benefits in a statistically significant way. The results indicate that the diversification contribution varies greatly amongst the different commodities. Industrial metals, agriculturals and livestock contribute to the reduction of risk, while energy and precious metals contribute to both the reduction of the level of risk and to the improvement of return. The differentiation between bull and bear markets reveals that investors can enhance the portfolio performance by changing exposure into individual commodities. Investors can benefit from the diversification gains through financial instruments as the diversification gains hold both in the sample of physical commodity and commodity futures. Overall, the results confirm that commodities are valuable investments from the perspective of diversification. (C) 2012 Elsevier B.V.

We provide a foundation of the notion of sustainability in portfolio theory and establish a general model for generalized safety first portfolio management with probabilistic constraints and three specifications of it. Moreover, we prove theorems about conditions for unique optimal solutions and for the constraints of one model being more restrictive than those of another. In an empirical part, we calculate the costs of investing according to our approach in terms of less financial return. (C) 2012 Elsevier B.V.

Every asset is assigned a social return, which is generally modeled as stochastic. We focus on the theoretical foundation and practical implications of portfolio choice with social returns. We apply the theoretical model to two different microfinance investments. First, we consider an investor who is risk-neutral in the social dimension and faces a small number of assets: an equity index, a bond index and a microfinance investment fund (MFIF). Second, we address the question of how MFIFs should allocate funds to microfinance institutions. article 2012 1470-8272,1479-179X Journal of Asset Management 13 Palgrave Macmillan 384-400 6 https://epub.uni-regensburg.de/id/eprint/25893 Gregor Dorfleitner Michaela Leidl Johannes Reeder article 2011 11 Blick in die Wissenschaft 24 Universit?tsverlag Regensburg 41-46 https://epub.uni-regensburg.de/id/eprint/22590 Gregor Dorfleitner Michaela Leidl This paper considers the financial optimization problem of a firm with several sub-businesses striving for its optimal RORAC. An insightful example shows that the implementation of classical gradient capital allocation can be suboptimal if division managers are allowed to venture into all business whose marginal RORAC exceeds the firm's RORAC. The marginal RORAC requirements are refined by adding a risk correction term that takes into account the interdependencies of the risks of different lines of business. It is shown that under certain stationarity conditions this approach can guarantee that the optimal RORAC will eventually be achieved. (C) 2011 Elsevier B.V.

The existing literature on structural CDS pricing is extended by allowing a general functional form for the default barrier specified without reference to asset volatilities, dividend yields or interest rates. We develop a fast and robust algorithm to compute survival probabilities numerically. An empirical application suggests that the market-implied barrier is stable over time, with a possibly hump-shaped term structure. The implied barrier can be used for computing survival probabilities consistent with objective expectations of asset evolution, for pricing under counterparty risk, and for determining optimal corporate bond covenants. article 2011 1469-7688,1469-7688 10.1080/14697688.2010.481633 Quantitative Finance 11 ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD

Results show that an index modeling approach without detrending captures the prices exceptionally well. Moreover, weather forecasts significantly influence prices up to 11 days ahead. It is shown that valuations of temperature futures relying on a model without detrending yield biased valuations by over-pricing winter contracts and underpricing summer contracts. Several trading strategies are devised to exploit the mispricing observed at the CME and to demonstrate that speculating on temperature futures can not only generate high overall returns, but also perform well on a risk-adjusted basis.

The data set comes out with an initial return mean of 88.67%, an average market-adjusted initial return of 89.61% and an average market-adjusted log-return of 59.18%, which are significantly lower than the results of former empirical studies. This downward trend of IPO returns reinforces the explanation that a transition economy reduces its cheap state assets sell-off in line with the maturing of its capital market. Based on the results of correlation and regression analysis, we ascertain that the IPO underpricing is overwhelmingly caused by the excess demand and the generally positive sentiment in China's secondary/after-IPO market for new shares, resulting in high trading turnover on the first listing day. This is strengthened by the finding that more initial returns could be generated on the SHSE than on the SZSE, as a result of strong public interest in blue chip IPOs on the SHSE. article 2008 1 10.1080/09603100601007172 Applied financial economics 18 Routledge 9-22 1 https://epub.uni-regensburg.de/id/eprint/3803 Haini Deng Gregor Dorfleitner article 2007 Zeitschrift für Betriebswirtschaft 77 Gabler/GWV-Fachverlag 141-170 2 https://epub.uni-regensburg.de/id/eprint/3804 Arne Buch Gregor Dorfleitner article 2007 Review of managerial science 1 Springer 47-63 1 https://epub.uni-regensburg.de/id/eprint/3808 Michael Krapp Gregor Dorfleitner book_section 2006 978-3-540-27691-3; 3-540-27691-2 Kapitalmarkt, Unternehmensfinanzierung und rationale Entscheidungen: Festschrift für Jochen Wilhelm Springer

Ferner werden als marktorientierte Bewertungsverfahren die exakte Duplizierung, die relaxierte Duplizierung und CAPM-basierte Ans?tze in verschiedenen Varianten diskutiert. Intertemporale Abh?ngigkeiten sind hierbei zumeist irrelevant. article 2004 0340-5370,0006-002x Betriebswirtschaftliche Forschung und Praxis 56 Verl. Neue Wirtschaftsbriefe 101-118 2 https://epub.uni-regensburg.de/id/eprint/3811 Michael Krapp Gregor Dorfleitner Günter Bamberg Returns can be defined as log returns or as simple returns. Whereas on a numerical level the difference between these two terms is small as long as the return values are close to zero, there can be non-negligible differences if we look at expected values and (co)variances in a stochastic context. This paper examines the consequences of mixing up the two return terms when variances and convariances are considered. Three applications show that these consequences can be severe in the sense of suboptimal portfolio selection or invalid betas. The paper argues that more awareness of the suited return term is necessary. article 2003 2 International Journal of Theoretical & Applied Finance 6 World Scientific 73-86 1 https://epub.uni-regensburg.de/id/eprint/3812 Gregor Dorfleitner book_section 2003 3-211-40756-1 Planning based on decision theory 472 Springer

Closing behavior of the market participants captured in three distribution functions. article 2000 Journal of Economics and Finance 24 Springer 246-259 3 https://epub.uni-regensburg.de/id/eprint/4071 Gregor Dorfleitner Günter Bamberg Um einen Aktienindex exakt nachzubilden, mu? man die Gewichtungsfaktoren des Indexes mit dem gewünschten Index-Vielfachen multiplizieren und erh?lt so die Anzahlen der jeweils zu haltenden Aktien. Rundet man diese Anzahlen auf herk?mmliche Art, so weicht man vom gewünschten Nachbildungsergebnis h?ufig weiter als n?tig ab. In dieser Arbeit wird ein leicht zu implementierender Algorithmus vorgestellt, der dieses Problem auf Basis einer Multiplikator-Rundungsmethode l?st. Als konkretes Anwendungsbeispiel wird gezeigt, wie man dieses Verfahren beim Nachbilden des Deutschen Aktien-Indexes (DAX) anwenden kann. Dabei finden auch im Xetra-Handel übliche Stückzahlrestriktionen Berücksichtigung. Der Algorithmus reduziert den Nachbildungsfehler und damit auch den daraus resultierenden Tracking-Error auf einen Bruchteil des Wertes, den man bei herk?mmlicher Rundung erh?lt. article 1999 10 0171-6468,1436-6304 10.1007/s002910050100 OR Spectrum 21 Springer 493-502 4 https://epub.uni-regensburg.de/id/eprint/4073 Gregor Dorfleitner Die meisten Index-Futures-Positionen werden nicht bis Ablauf gehalten, sondern vorzeitig glattgestellt, etwa mittels eines Limitauftrags. {web_name}e Vorgehensweise wird in der vorliegenden Arbeit auf ihre Vorteilhaftigkeit hin untersucht. Dabei wird der Verlauf des Futures-Kurses als geometrische Brownsche Bewegung mit Drift modelliert, wodurch interessierende Gr??en wie die Erfolgswahrscheinlichkeit oder der Erwartungswert der Limit-Strategie durch Rückgriff auf Erkenntnisse aus der Theorie stochastischer Prozesse berechenbar werden. Da bei schlichter Erwartungswert- bzw. Nutzenerwartungswertmaximierung der Limitauftrag nur in Spezialf?llen als günstig gelten kann, wird die Erwartungswertmaximierung auch unter einer Value-at-Risk-Restriktion durchgeführt. Dabei ergeben sich interessante Hinweise zur Gestaltung des Limitauftrages. Eine ?bertragung der Resultate auf andere Assets, deren kumulierte Rendite durch eine geometrische Brownsche Bewegung approximiert werden kann, ist generell m?glich. article 1999 2 0171-6468,1436-6304 10.1007/s002910050088 OR Spectrum 21 Springer 239-257 1-2 https://epub.uni-regensburg.de/id/eprint/4072 Gregor Dorfleitner Günter Bamberg book_section 1999 3-540-65855-6 Classification in the information age: proceedings of the 22nd Annual GfKl Conference, Dresden, March 4 - 6, 1998 Springer
