2nd CEFGroup Climate Finance Symposium an der Otago Business School

Professor Lars Hornuf as speaker at the 2nd CEFGroup Climate Finance Symposium at Otago Business School

Today Professor Lars Hornuf presents his research project Do Retail Investors Value Environmental Impact? at the 2nd CEFGroup Climate Finance Symposium at Otago Business School.

Are investors willing to give up a higher return if the investment generates positive environmental impact? Lars Hornuf and his co-author Christoph Siemroth from the University of Essex investigate this question with a decision experiment among crowdfunders, in which they choose between a higher return or environmental impact. Overall, 65% of investors choose environmental impact at the expense of a higher return for sufficiently large impact, 14% choose impact independent of the magnitude of impact, while 21% choose the higher return independent of impact. Combining the experimental data with historical investments, the authors find that investors allocate a larger share of funds to green projects if they value environmental impact more, and if they expect green projects to be more profitable. These findings suggest that investors have a preference for positive environmental impact, and satisfy it by investing in green projects. The authors further show that the preference for environmental impact is distinct from a preference for positive social impact. Finally, the authors introduce new survey measures of impact for future use, which are experimentally validated and predict field behavior.

Professor Lars Hornuf as Speaker at the European Privacy, InfoSec & Compliance Summit

On November 17th, Professor Lars Hornuf presented his research project Promise Not Fulfilled: FinTech, Data Privacy, and the GDPR at the European Privacy, InfoSec & Compliance Summit in Munich.

This research project analyzes how the General Data Protection Regulation (GDPR) has affected the privacy practices of FinTech firms. Hornuf and his coauthors from the University of Regensburg study the content of 308 privacy statements respectively before and after the GDPR became binding. Using textual analysis methods, they 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 processing of personal data. The authors also analyze the content of privacy statements and link it to company- and industry-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, they document mimicking behavior among industry peers with regard to the data processed and transparency.

Lock-In Effects in Online Labor Markets

New Working Paper about Lock-In Effects in Online Labor Markets

Professor Dr. Lars Hornuf has published a new working paperunder the title "Lock-In Effects in Online Labor Markets." The article emerged in collaboration with his PhD student Eliza Stenzhorn and Fabrizio Ciotti from UCLouvain.

The article reports on an investigation of the role of lock-in exploitation and the impact of reputation portability on workers' switching behaviors in online labor markets. Online platforms using reputation mechanisms typically prevent users from transferring their ratings to other platforms, inducing lock-in effects and high switching costs and leaving users vulnerable to platform exploitation. With a theoretical model, in which workers in online labor markets are locked-in by their reputational data, the authors test the effects using an online lab-in-the-field decision experiment. In addition to comparing a policy regime with and without reputation portability, they vary lock-in exploitation using platform fees to consider how switching behavior might differ according to monetary motives and fairness preferences. Theoretically, this study reveals how reputational investments can produce switching costs that platforms can exploit. Experimentally, the results suggest that reputation portability mitigates lock-in effects, making users less susceptible to lock-in exploitation. The data further show that switching is driven primarily by monetary motives, but perceiving the fee as unfair also has a significant role.

Frankfurt

Professor Lars Hornuf as Speaker at the Workshop on "AI & FINANCE"

29 October 2021

Today, Professor Lars Hornuf will present his research project „The Social Dilemma of Big Data“ at the Workshop on "AI & FINANCE“ at Goethe-University Frankfurt.

By implementing an online experiment among 1,696 US citizens together with his co-author Kirsten Hillebrand, he finds that individuals would donate their data even when at risk of getting leaked. The willingness to provide personal data depends on the risk level of a data leak but not on a realistic impact of the data on social welfare. Individuals are less willing to donate their data to the private industry than to academia or the government. Finally, individuals are not sensitive to whether the data are processed by a human-supervised or a self-learning smart assistant. The necessity to mobilize individual user data has recently become omnipresent in the context of governmental policies to fight the COVID-19 pandemic. Various countries around the world have developed and implemented tracking apps that use personal infection and location data to help control the spread of the virus and to protect public health. The research project helps to solve the social dilemma associated with donating personal data.

CESifo Working Papers

New Publication about Disclosure Deregulation of Quarterly Reporting

20 October 2021

Professor Dr. Lars Hornuf has published a new article in the CESifo Working Paper Series under the title "Disclosure Deregulation of Quarterly Reporting." The article emerged in collaboration with Vanessa Behrmann and Professor Dr. Jochen Zimmermann.

The authors investigate the deregulation efforts resulting from the 2015 transposition of the EU’s Transparency Directive into German law and analyze whether a reduction in the minimum content requirements for quarterly reporting increases information asymmetries and decreases firm value. Using a novel dataset of firms that are listed on the Frankfurt Stock Exchange, the results reveal that over the period from 2012 to 2019, lower quarterly reporting levels on average have increased information asymmetry and reduced firm value. The authors find that this effect is stronger for second-tier stocks and firms with low media coverage. The results are robust to potential selection effects regarding firms’ choice of quarterly reporting content levels.

Journal of Technology Transfer

New Publication in the Journal of Technology Transfer

18 October 2021

Professor Dr. Lars Hornuf has published a new article in the Journal of Technology Transfer under the title "Are sustainability-oriented investors different? Evidence from equity crowdfunding." The article emerged in collaboration with his PhD student Eliza Stenzhorn and Dr. Tim Vintis from the University of Bremen.

The authors investigate how investors' motives affect their investment behavior in equity crowdfunding. In particular, the authors compare the investment behavior of sustainability-oriented investors with ordinary crowd investors on six leading equity crowdfunding platforms in Austria and Germany. They evidence that, according to Dorfleitner et al. (2019), default shock in equity crowdfunding usually occurs immediately after the event or when investors become insolvent more than twice. Moreover, by distinguishing between sustainability-oriented and ordinary crowd investors, the authors show that sustainability-oriented investors pledge higher amounts and invest in more campaigns. The results are consistent with the notion that sustainability-oriented investors care about nonfinancial returns because they react more negatively when they experience a default in their portfolio, suggesting that they suffer beyond pure financial loss. The findings contribute to the recent literature on equity crowdfunding, socially responsible investing, and further demonstrate how individual investment motives and personal experiences influence investment decisions.

Prof. Dr. Lars Hornuf speaks to the Young Talent Group of the Federal Ministry for Economic Affairs and Energy

20 July 2021

In the course of increasing digitalization, the collection, processing and analysis of data are becoming more and more a basis for technical progress and prosperity. Data has become the new “oil” of our digitized world, which enables new business models and innovations to flourish. The development of groundbreaking technologies such as autonomous vehicles is ultimately based on the availability of large amounts of data.

Valid data from users is also of central importance for the public sector for important research projects, for the promotion of start-ups or for government projects in the field of digitalization. The Covid 19 pandemic in particular has shown how important the provision of data on a voluntary basis is for the common good, for example, in order to develop a powerful Corona warning app.

But how can incentives be created so that more citizens want to voluntarily provide their data for private or public purposes? What factors are conducive to citizens' behavior of donating their data for public purposes? Which factors are more of a hindrance? Where could the state start to stimulate the voluntary donation of data by citizens for charitable purposes while maintaining data protection and thereby promoting innovation?

These and many other questions will be answered by Prof. Dr. Lars Hornuf, of the Chair of Business Administration, in particular Financial Services and Financial Technology at the University of Bremen, in a lecture at the Federal Ministry for Economic Affairs and Energy this Friday. He has agreed to discuss the topic "Data transfer for public goods and innovations: From the Corona warning app to autonomous driving" with the BMWi's Young Leaders Group.

Title: The Index Effect: Evidence from the Option Market

Dr. Fabian Hollstein, of Leibniz University Hannover will give a talk on "The Index Effect: Evidence from the Option Market" during the upcoming Finance Research Seminar:

"We document a significantly positive response of delta-hedged option positions on companies entering or leaving the S&P 500 index. Our findings (i) hold for both call and put options, (ii) are robust to placebo- and risk-adjustments, and (iii) are stronger for companies  that are likely subject to more demand pressure from stock index investors. The inclusion effect is permanent, while the exclusion effect is transitory. We explore various mechanisms to explain these results, including leading theories of benchmarking, investor recognition, noise trading, and dispersion trading. We find that these explanations cannot individually account for all our novel results."

Sorbonne

Professor Lars Hornuf as Speaker at the Paris Webinar on Financial Technology and Crypto

27 May 2021

This week Professor Lars Hornuf presented his paper "The Local Bias in Equity Crowdfunding: Behavioral Anomaly or Rational Preference?" at the Paris Webinar on Financial Technology and Crypto. The paper was written in collaboration with PhD student Eliza Stenzhorn and Dr. Matthias Schmitt.

The authors use hand-collected data of 20,460 investment decisions and two distinct portals to analyze whether investors in equity crowdfunding direct their investments to local firms. In line with agency theory, the results suggest that investors exhibit a local bias, even when we control for family and friends. In addition to the regular crowd, our sample includes angel-like investors, who invest considerable amounts and exhibit a larger local bias. Well-diversified investors are less likely to suffer from this behavioral anomaly. The data further show that portal design is important for attracting investors more prone to having a local bias. Overall, we find that investors who direct their investments to local firms more often pick start-ups that run into insolvency or are dissolved, which indicates that local investments in equity crowdfunding constitute a behavioral anomaly rather and a rational preference. Here again, however, portal design plays a crucial role.

On Tuesday, January 19, Professor Dr. Lars Hornuf gave a talk about "Playing the Angel: Decomposing the Value of Early-Stage Investors" at the Finance Research Seminar at TU Munich.

Together with his coauthor Professor Dr. Daniel Blaseg from ESADE Business School he is analyzing the determinants of funding success and consequent firm performance of 2768 early stage ventures that made a business pitch during the Canadian, German, UK or US versions of the reality television show Dragons' Den.

Consistent with business angel (BA) and venture capital research they find geographic and industry closeness, the existence of patents and prototypes as well as the authenticity and tonality of the entrepreneurial pitch to have a positive effect on founders getting a deal during the show. Using a relative weight analysis, they evidence that the money BA provide and the screening they undertake are by themselves the most important factor regarding venture survival, subsequent propensity to generate web traffic, and sales. Moreover, having a well-known and well-connected BAs as board member trumps the existence of patents and prototypes with regard to post funding venture performance. These findings have broader implications for BA finance and other nascent players in the entrepreneurial finance ecosystem.

Talk by Lars Hornuf at the 4th Social Impact Investments International Conference

On Friday, December 4, Professor Lars Hornuf will present the paper "Are Sustainability-Oriented Investors Different? Evidence from Equity Crowdfunding" at the at the 4th Social Impact Investments International Conference. The paper was written in collaboration with PhD students Eliza Stenzhorn and Tim Vintis.

"In this article, we examine how investor motives affect investment behavior in equity crowdfunding. In particular, we compare the investment behavior of sustainability-oriented with ordinary crowd investors on six leading equity crowdfunding platforms in Austria and Germany and investigate whether they suffer from a default shock that was recently identified by Dorfleitner et al. (2019). In general, we find evidence of a default shock in equity crowdfunding that occurs immediately after the event and if investors experience more than two insolvencies.

Moreover, we find that sustainability-oriented investors pledge larger amounts of money and invest in more campaigns than ordinary crowd investors. The results also suggest that sustainability-oriented crowd investors care about non-financial returns, as they react more sensitively after experiencing a default in their equity crowdfunding portfolios, which indicates that they suffer beyond the pure financial loss. These findings contribute to recent literature on equity crowdfunding, socially responsible investing, and how individual investment motives and personal experiences affect investment decisions."

Talk at the CESifo Area Conference on Economics of Digitization

Prof. Dr. Lars Hornuf will present his paper "How Community Managers Affect Online Idea Crowdsourcing Activities” at the CESifo Area Conference on Economics of Digitization 2020.In associated working paper, he investigates with his coauthor Prof. Dr. Sabrina Jeworrek from IWH Halle, whether and to what extent community managers in online collaborative communities can stimulate crowd activities through their engagement. Using a novel data set of 22 large online idea crowdsourcing campaigns, the authors find that active engagement of community managers positively affects crowd activities in an inverted U-shaped manner.

Moreover, they evidence that intellectual stimulation by managers increases community participation, while individual consideration of users has no impact on user activities. Finally, the data reveal that community manager activities that require more effort, such as media file uploads instead of simple written comments, have a larger effect on crowd participation.

The influence of the COVID-19 pandemic on the digital transformation of work – new publication

Lisa Nagel, PhD student at the Chair of Business Administration, in particular Financial Services and Financial Technology, has published a paper on the impact of COVID-19 on the digital transformation of work in the International Journal of Sociology and Social Policy. The COVID-19 pandemic took the world by surprise in early 2020, and the economy has continued to face a substantial downturn, which has implications for working situations. Voluntary precautions against COVID-19, as well as mandatory government restrictions, have forced companies to increasingly offer employees the option of working at home, and thus a large number of people exclusively working from home have integrated existing technologies into their daily work routines. But does the COVID 19 pandemic have the ability to accelerate digital transformation in the workplace? The study assesses the consequences of the COVID-19 pandemic on the future of work, showing that changes in the perception of digital transformation and the willingness to work exclusively in a digital manner have arisen as result of the COVID-19 pandemic.

Paralyzed by Shock: The Portfolio Formation Behavior of Peer-to-Business Lending Investors

Talk by Lars Hornuf at the 4th European Alternative Finance Research Conference

On Tuesday, October 6, Professor Lars Hornuf will present his paper "Paralyzed by Shock: The Portfolio Formation Behavior of Peer-to-Business Lending Investors" at the 4th European Alternative Finance Research Conference. The paper was written in collaboration with Professor Dr. Gregor Dorfleitner and Dr. Martina Weber from the University of Regensburg. In this article, the authors study the investor behavior on a leading peer-to-business lending platform and identify a new investment mistake – a default shock bias. First, they find that investors stop investing in new loans and cease from 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 could have been expected based on 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 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. The full article can be downloaded here.

New article on "How do banks interact with fintech startups?" in Small Business Economics

Prof. Dr. Lars Hornuf has published a new article in Small Business Economics together with Todor Lohwassers and Milan Klus (both WWU Münster) as well as Prof. Dr. Armin Schwienbacher (Skema Business School). 

The article "How do banks interact with fintech startups?" examines the increasing pervasiveness of technology-driven firms that offer financial services. The article finds that this development has led to growing pressure on traditional banks to modernize their core business activities and services. Many banks tackle the challenges of digitalization by cooperating with startup firms that offer technology-driven financial services and novel service packages (fintechs). In their article, the authors examine which banks typically collaborate with fintechs, how intensely they do so, and which form of alliance they prefer. Using hand-collected data covering the largest banks from Canada, France, Germany, and the United Kingdom, the authors provide detailed evidence on the different forms of alliances occurring in practice.

They show that banks are significantly more likely to form alliances with fintechs when they pursue a well-defined digital strategy and/or employ a chief digital officer. Moreover, in line with incomplete contract theory, they find that banks more frequently invest in small fintechs but often build product-related collaborations with larger fintechs.

Cover CESifo Working Paper No. 7962

New working paper on Initial Coin Offerings, Information Disclosure, and Fraud

The research work by Lars Hornuf and Theresa Kück in collaboration with Armin Schwienbacher (SKEMA Business School) on "Initial Coin Offerings, Information Disclosure, and Fraud" is now available as a working paper. In their work, they come to the conclusion that in some cases with ICOs, disclosure on the Github platform is not a good idea. In addition, Gary Becker was right that stealing only makes sense when it comes to substantial amounts of money.

Abstract of the working paper:

We study the extent of fraud in initial coin offerings (ICOs), and whether information disclosure prior to the issuance predicts fraud. We document different types of fraud, and that fraudulent ICOs are on average much larger than the sample average. Issuers that disclose their code on GitHub are more likely to be targeted by phishing and hacker activities, which suggests that there are risks related to disclosing the code. Generally, we find it extremely difficult to predict fraud with the information available at the time of issuance. This calls for the need to install a third-party that certifies the quality of the issuers, such as specialized platforms, or the engagement of institutional investors and venture capital funds that can perform a due diligence and thus verify the quality of the project.

How does this affect the attractiveness of Germany as a market? Is Germany likely to follow the examples of places like London and Lithuania in starting a sandbox for new business models to be tested in? How can we ensure that we fuel European innovation, rather than simply regulating imports from the US and China?

Professor Hornuf speaks at the Law Finance and Technology Lunchtime Workshop at the Universität Hamburg

On Thursday, December 5, 2019, Professor Lars Hornuf will present the topic "Are Equity Crowdfunding Investors Active Investors?" at the LFT Lunchtime Workshop. The event will take place from 12:30 to 13:30 in WiWi Bunker Room 1083a at the University of Hamburg. The event will be based on one of professor Hornuf recent working papers: "It is often assumed that entrepreneurs retain more control of their venture when they opt for equity crowdfunding as compared to venture capital, notably because crowd investors are passive. We study whether crowd investors are indeed passive by analysing the cash flow and control rights crowd investors receive in equity crowdfunding in Germany where more flexible contracts are offered than in many other countries. We document that in Germany, many of the rights used in venture capital investment contracts are also used in equity crowdfunding contracts. We find that crowd investors are asked to pay higher prices if they receive more cash flow and exit rights consistent with the fact that these rights are valuable to the crowd. However, these rights have no meaningful economic impact since they do not affect campaign outcome the likelihood of securing follow-on funding nor the likelihood of liquidation of the venture. These results are inconsistent with control rights theory that predicts positive impacts and is in contrast with results documented for venture capital contracts. Rather, our results suggest that crowd investors are passive investors whose control rights are ineffective or not exercised.“

Digital financial actors: Data protection still defective despite GDPR

A study involving the economist Lars Hornuf from the University of Bremen has investigated the state of data protection of German FinTech companies. The results show that the handling of user data has even deteriorated in many cases since the General Data Protection Regulation (GDPR) was implemented. Most frequently, consumers are still hardly able to understand how their data is processed.

Lock-in_Effects_in_Online_Labor_Markets

Professor Lars Hornuf as Speaker at the CESifo Area Conference on the Economics of Digitization

Last week Professor Lars Hornuf presented his project Lock-in Effects in Online Labor Markets at the CESifo Area Conference on the Economics of Digitization 2021  in München.

Together with his coauthors Fabrizio Ciotti und Eliza Stenzhorn, Professor Lars Hornuf analyzes the role of lock-in exploitation and the impact of reputation portability on workers’ switching behavior in online labor markets. Online platforms using reputation mechanisms typically prevent users to transfer their ratings to other platforms. This leads to lock-in effects and high switching costs, which make users vulnerable to platform exploitation. The researchers build a theoretical model in which workers in online labor markets are locked-in because of their reputational data and test its prediction in an online lab-in-the-field decision experiment. They compare a policy regime with and without reputation portability. Furthermore, they vary lock-in exploitation with platform fees to study switching behavior based on monetary motives and fairness preferences. Theoretically, they show how reputational investments can become switching costs that platforms can exploit. Experimentally, the results suggest that reputation portability mitigates lock-in effects, making users less susceptible to lock-in exploitation. The data further show that switching is foremost driven by monetary motives, but fairness preferences also play a significant role.

Professor Lars Hornuf as speaker at the Sustainable Finance Research Seminar of the University of Zurich

On November 4th, Professor Lars Hornuf presented his research project Do Retail Investors Value Environmental Impact? at the Sustainable Finance Research Seminar of the University of Zurich.

Are investors willing to give up a higher return if the investment generates positive environmental impact? Lars Hornuf and his co-author Christoph Siemroth from the University of Essex investigate this question with a decision experiment among crowdfunders, in which they choose between a higher return or environmental impact. Overall, 65% of investors choose environmental impact at the expense of a higher return for sufficiently large impact, 14% choose impact independent of the magnitude of impact, while 21% choose the higher return independent of impact. Combining the experimental data with historical investments, the authors find that investors allocate a larger share of funds to green projects if they value environmental impact more, and if they expect green projects to be more profitable. These findings suggest that investors have a preference for positive environmental impact, and satisfy it by investing in green projects. The authors further show that the preference for environmental impact is distinct from a preference for positive social impact. Finally, the authors introduce new survey measures of impact for future use, which are experimentally validated and predict field behavior.

Journal of Business Ethics

New Publication in the Journal of Business Ethics

20 October 2021

Professor Dr. Lars Hornuf has published a new article in the Journal of Business Ethics under the title "Disentangling Crowdfunding from Fraudfunding." The article emerged in collaboration with Prof. Douglas Cumming from Florida Atlantic University, Professor Dr. Denis Schweizer und Dr. Moein Karami (both Concordia University). The Journal of Business Ethics is a FT-50 List Journal.

Fraud in the reward-based crowdfunding market has been of concern to regulators, but it is arguably of greater importance to the nascent industry itself. Despite its significance for entrepreneurial finance, our knowledge of the occurrence, determinants, and consequences of fraud in this market, as well as the implications for the business ethics literature, remain limited. In this study, the authors conduct an exhaustive search of all media reports on Kickstarter campaign fraud allegations from 2010 through 2015. The authors then follow up until 2018 to assess the ultimate outcome of each allegedly fraudulent campaign. First, the authors construct a sample of 193 fraud cases, and categorize them into detected vs. suspected fraud, based on a set of well-defined criteria. Next, using multiple matched samples of non-fraudulent campaigns, the authors determine which features are associated with a higher probability of fraudulent behavior. Second, the authors document the short-term negative consequences of possible breaches of trust in the market, using a sample of more than 270,000 crowdfunding campaigns from 2010 through 2018 on Kickstarter. The results show that crowdfunding projects launched around the public announcement of a late and significant misconduct detection (resulting in suspension) tend to have a lower probability of success, raise less funds, and attract fewer backers.

New Publication in the Strategic Entrepreneurship Journal

14 October 2021

Professor Dr. Lars Hornuf has published a new article in the Strategic Entrepreneurship Journal under the title "Marketplace lending of small- and medium-sized enterprises." The article emerged in collaboration with Prof. Douglas Cumming from Florida Atlantic University. The Strategic Entrepreneurship Journal is a FT-50 List Journal and ranked “A” in the VHB-JOURQUAL3 Ranking.

When evaluating Internet-based loan project of small and medium size enterprises (SME), lenders can rely on easy-to-understand risk ratings or more sophisticated financial information. The authors investigate lenders decisions and its effect on loan funding success on the marketplace-lending platform Zencap. The data set has been provided by the platform Zencap and includes 414 SME marketplace loans and 2,196 lenders. The data examined provide strong support for the importance of simple platform ratings in influencing investor behavior, while the effect of more detailed financial information is less pronounced, controlling for relevant variables. Higher interest rates appear more profitable to investors without any serious concern about non-repayment.

Title: Streaks in Daily Returns

Prof. Dr. Simon Rottke, of University of Amsterdam will give a talk on "Streaks in Daily Returns" during the upcoming Finance Research Seminar:

"A simple model of return extrapolation suggests that streaks in returns, which we define as n-day consecutive over-/under-performance relative to the market, predict future returns. We test this prediction using daily U.S. data and find strong empirical support. Buying stocks with negative streaks and selling stocks with positive streaks yields annualized Sharpe ratios around 2. We replicate the results in international markets and are able to increase the Sharpe ratio to above 3 by diversifying across regions. We argue that liquidity is unlikely to explain the results as streak portfolio returns based on mid-quote-prices are strongest among stocks with the lowest bid-ask spreads."

New Publication in the Journal of Corporate Finance

Professor Dr. Lars Hornuf has published a new article in the Journal of Corporate Finance under the title "The relevance of investor rights in crowdinvesting." The article emerged in collaboration with Tobias Schilling and Prof. Dr. Armin Schwienbacher of Skema Business School.

A common assumption is that entrepreneurs retain more control of their venture when opting for crowdinvesting rather than venture capital. In this article, the authors investigate the relevance of cash-flow, control, and exit rights awarded to crowd investors in Germany, where more flexible contracts are offered than in many other jurisdictions. In Germany, many of the rights used in venture capital investment contracts are also prevalent in crowdinvesting contracts. The authors find that crowd investors are asked to pay higher prices if they receive more cash-flow and exit rights, consistent with the view that these rights are valuable to the crowd. However, they find no evidence that these rights affect campaign outcome, the likelihood of securing follow-on funding, or the insolvency likelihood of the venture. The authors interpret this as evidence that the redemption rights stipulated in the contract make other types of control rights less relevant or investors' actions are ineffective. Furthermore, crowd investors neither trigger insolvency proceedings nor mention the enforcement of their contractual rights in investor communication blogs or popular media.

Lars Hornuf presents research projects at the Data Science Forum

11 March 2021

Today, Professor Lars Hornuf will present two ongoing research projects at the Data Science Forum, which illustrate the methods and data used in state-of-the-art business research. Does it matter for business success how prominent an investor is? Together with his coauthor Professor Daniel Blaseg from ESADE Business School Lars Hornuf analyzes the determinants of funding success and consequent firm performance of 2768 early-stage ventures that made a business pitch during the Canadian, German, UK or US versions of the reality television show Dragons’ Den. The data was in part scraped from public sources and classified using machine learning tools. What motivates crowd funders to support projects on online crowdfunding platforms? To answer this question, Lars Hornuf and his coauthor Professor Christoph Siemroth from Essex University apply the nowadays “gold-standard” in economics and business research: field experiments. Lars Hornuf will give a brief introduction why and how this method is applied today.

New Publication in Business Research (BuR)

Dr. Milan Klus has published a new article in Business Research (BuR) entitled „Success factors of academic journals in the digital age“. The article emerged in collaboration with Prof. Dr. Alexander Dilger from the University of Münster.

Since the early 1990s, when digitalisation began to open new opportunities for disseminating information, many academic journals started to introduce online services. However, while some studies suggest that online availability and free access to journal articles are positively connected to the number of citations an article receives, little is known about whether being an early adopter of digital services provides journals with a (long-term) competitive advantage in times of digital change. The authors use data from SSCI-listed management journals to examine which journals pioneered the introduction of digital services, to what extent first-mover advantages can be identified, and which journal characteristics are associated with citation-based performance indicators.

The results show that lower ranked journals were the first to introduce digital services and were beneficiaries of the digital age. Furthermore, the authors find a negative correlation between general submission fees and journal performance and that the top-performing journals of their sample are those of non-commercial publishers. The analysis of the relationship between journal performance and the provision of open access contradicts previous studies, as the authors find no positive correlations between performance and open access on the journal level.

New Publication in Information Systems and e-Business Management

Dr. Milan Klus has published a new article in Information Systems and e-Business Management entitled „Value propositions of chatbots to support innovation management processes“. The article emerged in collaboration with Prof. Dr. Florian Johannsen from the Hochschule Schmalkalden and Dorina Schaller.

Chatbots have become popular in recent years as a means of supporting a company’s external communication with customers, but they are also increasingly being used for internal purposes, especially to improve and accelerate workflows. Along these lines, recent studies have suggested that chatbots can also be applied to other internal business practices, such as innovation management. Nevertheless, the use of chatbots for innovation management is still an under-researched topic, and practical experiences are largely missing.

The authors address this gap by identifying value propositions of chatbots to support a company’s innovation management process. Furthermore, they link the value propositions to particular process steps and success dimensions. To do so, they perform a literature review and complement the findings with expert interviews. The study contributes to a better understanding of the benefits of chatbot usage for the innovation management process.

Diginomics Research Talks meet BREMEN.AI Data Lounge

1. Dezember 2020, 18:00 Uhr

On December 1, 2020, the Diginomics Research Group of the University of Bremen hosts Dr Michael Engel, Head of Data & AI Product Management at VW Financial Services. The event is co-organized by BREMEN.AI Data Lounge and the Data Science Center.

Topic: AI Product Management

Dr Engel will give an introduction into AI product management - a topic many companies struggle to succeed with. In this talk, Dr Engel discusses a product-level approach towards creating value by using AI. He is going to show how product management concepts enable data science teams to frame the search for and implementation of ideas for innovation. In addition to that, Dr Engel will identify areas in which the product management frameworks for software products do not apply to AI products. Finally, he will discuss complementary approaches specific for AI products.

The background of this talk is given by the lacking abilities of many companies to deploy AI technologies to generate real customer value and eventually, economic impact. The problem derives from the entrenched habit to either using a firm-level AI strategy or a technology based approach by developing new models respectively algorithms. However, a data science team does not benefit from this in either way to maximize any short to medium-term profits.

The talk will take place as an online event via Zoom. The recording will be published later on YouTube.

Talk by Lars Hornuf at the University of Hamburg

On Wednesday, November 4, Professor Lars Hornuf will present the paper "Are Sustainability-Oriented Investors Different? Evidence from Equity Crowdfunding" at the Finance Accounting und Insurance Seminar at the University of Hamburg. The paper was written in collaboration with PhD students Eliza Stenzhorn and Tim Vintis.

"In this article, we examine how investor motives affect investment behavior in equity crowdfunding. In particular, we compare the investment behavior of sustainability-oriented with ordinary crowd investors on six leading equity crowdfunding platforms in Austria and Germany and investigate whether they suffer from a default shock that was recently identified by Dorfleitner et al. (2019). In general, we find evidence of a default shock in equity crowdfunding that occurs immediately after the event and if investors experience more than two insolvencies.

Moreover, we find that sustainability-oriented investors pledge larger amounts of money and invest in more campaigns than ordinary crowd investors. The results also suggest that sustainability-oriented crowd investors care about non-financial returns, as they react more sensitively after experiencing a default in their equity crowdfunding portfolios, which indicates that they suffer beyond the pure financial loss. These findings contribute to recent literature on equity crowdfunding, socially responsible investing, and how individual investment motives and personal experiences affect investment decisions."

New Publication in Technological Forecasting and Social Change

Professor Dr. Lars Hornuf has published a new article in Technological Forecasting and Social Change under the title "Protecting investors in equity crowdfunding: An empirical analysis of the small investor protection act." The article emerged in collaboration with Dr. Maximilian Goethner and Dr. Tobias Regner of the Friedrich Schiller University Jena.

During the past decade, equity crowdfunding (ECF) has emerged as an alternative funding channel for startup firms. In Germany, the Small Investor Protection Act became binding in July 2015, with the legislative goal to protect investors engaging in this new asset class. Since then, investors pledging more than 1,000 EUR now must self-report their income and wealth. Investing more than 10,000 EUR in a single ECF issuer is only possible through a corporate entity. The authors examine how the Small Investor Protection Act has affected investor behavior at Companisto, Germany's largest ECF portal for startup firms.

The results show that after the new law became binding, sophisticated investors invest less on average while casual investors invest more. Moreover, the signaling capacity of large investments has disappeared.

Silhouette München

Talk by Lars Hornuf at LMU Munich on Crowdfunding

On Wednesday, October 7, Professor Dr. Lars Hornuf will give a talk at the Center for Advanced Management Studies of LMU Munich. He will present the paper "Disentangling Crowdfunding from Fraudfunding," which he wrote in collaboration with Douglas Cumming from Florida Atlantic University and Moein Karami and Denis Schweizer from Concordia University. Using Kickstarter, the largest global reward-based crowdfunding platform, the authors conduct an exhaustive search of all fraud cases from 2010 through 2015 for nine different countries. While fraud in this new market has been of concern to regulators, it is arguably of greater importance to the nascent industry itself. They find that Kickstarter campaigns posted around a late and visible suspension of a crowdfunding campaign tend to have a lower probability of success, fewer backers, and raise less funds. Moreover, documenting the characteristics of fraudsters is of paramount importance.

The authors deploy the theoretical framework of the “Trust Triangle” to document campaign features that could be helpful to backers in detecting fraudsters in crowdfunding markets. The find fraudsters are less likely to have engaged in prior crowdfunding activities, are less likely to have a social media presence, and are more likely to provide easy-to-read campaign pitches with a greater number of enticements through pledge categories.

Prüfung Derivatehändler

Students trained as certified derivatives traders

This year, students from the Faculty of Business Studies and Economics participated in a lecture on financial derivatives and options held by Professor Dr. Lars Hornuf. The special feature of the lecture is that the students can also take the examination to become a "Certified Derivatives Trader" at the Frankfurt Stock Exchange afterwards. By attending the lecture on financial derivatives and options, the students are exempted from the course fee of several thousand euros by the Frankfurt Stock Exchange. The best three of the 17 candidates - Tobias Boberg, Daniel Hoffrogge and Benedikt Plate - were also reimbursed the examination fee by the Bremen Stock Exchange Foundation. We congratulate all the students who passed this demanding examination and wish them continued success in their studies and on the capital market.

Mr. Boberg is expected to complete his Bachelor's degree in 2021. Afterwards he would like to gain practical experience on the stock exchange. Currently he is working with the statistical software MATLAB in order to be able to develop his own algorithms for investment purposes later on. Mr. Hoffrogge has been a student assistant at the Chair of Economics, in particular Macroeconomics, since 2019 and recently completed his bachelor thesis on "Were sustainable European equity funds more resilient than conventional ones during the Corona crisis?" with an excellent grade. Mr. Hoffrogge plans to start a master's program next year at the financial center Frankfurt. Until then he would like to gain practical experience in the financial sector. Mr. Plate has been a student assistant at the Chair of Business Administration, Accounting and Control for one year and will complete his bachelor's degree this year. Starting in October, he will complete an internship in the field of restructuring and deal advisory in Hamburg and then start his master studies at the University of Bremen.

The German FinTech market in 2020 - new essay publication in the ifo Schnelldienst

Professor Dr. Lars Hornuf, in cooperation with Lena Wannenmacher and Professor Dr. Gregor Dorfleitner of the University of Regensburg, has published a new article in the current issue of the journal ifo Schnelldienst.

The FinTech sector is a dynamically growing market in which new business models and segments are constantly emerging. The new players are associated with considerable opportunities, but also significant risks for the financial market, which is why a regular examination of the market sizes is important. Four years ago, data on the market volumes of German FinTech companies for the period from 2007 to 2015 were collected for the first time on behalf of the Federal Ministry of Finance and a forecast for the future market development was prepared.

In the essay, the market volumes are extrapolated until 2019 and the original forecasts are reviewed for their predictive value. Compared to the original forecasts, some sub-segments have clearly exceeded the forecast of the realistic scenario (crowdlending, robo-advice, investment and banking), while other sub-segments have so far fallen short of expectations (donation- and counter-performance-based crowdfunding, crowd investing, factoring).

New Study: “State Surveillance – Exploiting Fear during the 2020 Pandemic Crisis?”

During the current corona crisis, shops are closed, events are canceled, trade is reduced, and people are asked to stay at home. In almost all Western democracies, governments restricted basic civil rights, though little protest resulted. In a pandemic crisis, different rules seem to apply—but do different rules apply even for data protection? Governmental data collection measures are currently discussed and implemented without having been discussed preventively in case of a crisis. The timing of these measures may be ethically problematic, because individual preferences and decisions change when people feel fear.

In an online study with 1,156 respondents during the outbreak of the crisis in Germany, Kirsten Hillebrand, PhD student at the Professorship for Business Administration, in particular Financial Services and Financial Technology, investigated German citizens’ consent to voluntary location-data disclosure and state surveillance and what drives their consent in order to control the COVID-19 virus. Results show that (1) fear increases consent to voluntary data disclosure, and (2) fear increases consent to state surveillance directly and indirectly by fostering general distrust in others. Further studies on government measures and the willingness to share data are currently being prepared.

New publication about FinTech in Germany published in Frontiers in Artificial Intelligence

Lars Hornuf in collaboration with Barbara Brandl from the Goethe University Frankfurt published a new article on „Where Did FinTechs Come From, and Where Do They Go? The Transformation of the Financial Industry in Germany After Digitalization“ in Frontiers in Artificial Intelligence (Artificial Intelligence in Finance).

The authors investigate how the digitalization of financial services opened a window for new players in the financial industry. These start-ups take on tasks and functions previously reserved for banks, such as financing, asset management, and payments. In their article, the authors trace the transformation of the industry after digitalization. By using data on FinTech formations in Germany, they provide first evidence that entrepreneurial dynamics in the FinTech sector are not so much driven by technology as by the educational and business background of the founders.

Furthermore, they investigate the reactions of traditional banks to the emergence of these start-ups. In contrast with other emerging industries such as biotechnology, a network analysis shows that FinTechs have mostly engaged in strategic partnerships and only a few banks have acquired or obtained a financial interest in a FinTech. They explain the restraint of traditional banks to fully endorse the new possibilities of digitalized financial services with the characteristics of the technology itself and with the postponed fundamental decisions of banks to modernize their IT infrastructure

Prof. Hornuf mit Studenten auf der Fintech Week

Students from the University Bremen at Fintech Week

Students learn first-hand at Fintech Week, what German fintech companies were planning in the future.

On Thursday, November 7th, 2019, the five best students from the Fintech project module of Prof. Dr. Lars Hornuf attended Fintech Week in Hamburg. As part of the project module, the students analyze the business models of German and international fintech companies with regard to the competitiveness of their services, technology, and the regulatory and market environment. Many of the founders were present at Fintech Week, so that the students were able to get direct information about the strengths and weaknesses of the FinTechs. The conference students waived the conference fee of around EUR 900 each from the organizer. After a short lecture, Prof. Dr. Lars Hornuf participated in a panel discussion on “Regulators to the rescue - what fears and interests do regulators have to reconcile?” With Stefan Krautkrämer (FinTecSystems), Brian Reaves (Factris), Tanja Aschenbeck (Osborne Clarke) and Clas Beese (finletter) part.

Lecture by Theresa Kück at the European Alternative Finance Research Conference on "Initial Coin Offerings, Information Disclosure, and Fraud"

On Tuesday, October 15, 2019, Diginomics doctoral student Theresa Kück gave a lecture at the European Alternative Finance Research Conference on her working paper "Initial Coin Offerings, Information Disclosure, and Fraud", on which she is working together with Lars Hornuf (also Diginomics) and Armin Schwienbacher from SKEMA Business School. The conference is organized by the European Center for Alternative Finance (ECAF) at Utrecht University. The theme of this year's conference was "New forms of alternative finance for Small and Medium sized Enterprises". In addition to lectures on initial coin offerings, papers on crowdfunding and FinTech topics were also presented.

Do judges hate speculators?

People often express negative feelings towards speculators, who may have intensified since the recent financial crisis, when taxpayers' money was used to rescue financial institutions. In a lab-in-the-field experiment, Prof. Dr. Lars Hornuf and the jurist Prof. Dr. Lars Klöhn from the HU Berlin are investigating whether judges have a negative attitude towards speculators, which could affect their professional decision-making. They first interviewed 123 lawyers and 247 law students in Germany, who predicted that the judges would be biased against speculators in the experiment. However, in the actual experiment, 185 judges showed no such bias. In another experiment among 170 professional lawyers, however, they found a weak indication of bias towards speculators. The results suggest that an independent audience perceives unbiased judgments as biased. While literature usually indicates that there is a communication problem between lawyers and non-lawyers - i.e. between judges and the public - the authors note that this problem can also exist within the legal community. The publication on the experiments can be found here.

    New essay on equity crowdfunding campaigns

    Lars Hornuf, his current PhD student Eliza Stenzhorn and his former PhD student Matthias Schmitt have published a new paper on follow-up financing and default probabilities after an equity crowdfunding campaign. The paper shows that German companies are more likely to be financed by business angels or venture capital firms after an equity crowdfunding campaign. At the same time, the probability of default in Germany is also significantly higher than in the UK. The success of a company is mainly influenced by the size of the founding team and less by the number of patents applied for or granted. The article was published in the Corporate Governance: An International Review and can be downloaded here: https://doi.org/10.1111/c

    Workshop on digital change

    A workshop on online platforms took place on 16 and 17 November 2018 as part of the "Worlds of Contradiction" joint research initiative. At the invitation of Prof. Dr. Benedikt Buchner, Prof. Dr. Sebastian Kolbe, Prof. Dr. Ursula Rust (FB 6) and Prof. Dr. Lars Hornuf (FB 7), researchers discussed the consequences of platform economics for work environments, the economy, and society in an interdisciplinary perspective together with external experts and interested parties at the University of Bremen.  The participants gained insight into current research projects through speakers from the Universities of Bielefeld and Paderborn as well as the Leuphana University of Lüneburg. A clear need for interdisciplinary cooperation between the humanities, law, social and technology sciences was identified in order to find appropriate answers to the challenges of digital change.

    The event is intended as an introduction to future research initiatives and collaborations.
