The Influence of Financial Advisors on Household Portfolios: A Study on Private Investors Switching to Financial Advice

In: Working Paper

Category: Miscellaneous [Find it]

Abstract

Investment advisors have significant influence on private investors' financial decisions but empirical studies of their behavior are rare. Based on a large and unique data set of the detailed portfolio compositions and daily transactions of more than 65,000 customers of a large German direct bank, we first compare advised investors with groups of non-advised investors, including matched peers. We find that the effect of investment advice is probably less than assumed. To underline this finding, we conduct an event study comparing 597 investors before and after the decision to take regular investment advice. We find much higher trading activity after the event due to advisors re-structuring clients' portfolios, less risky and speculative trading and rising diversification.

Interbankenentgelte - ökonomisch notwendig oder wettbewerbsverzerrend?

In: Zeitschrift für das gesamte Kreditwesen, Ausgabe 17, 822-825

Category: Publications in journals

Abstract

Nicht erst seit dem laufenden Geldausgabeautomatenstreit zwischen den Sparkassen und der ING Diba wird das Thema Interbankenentgelte heiß diskutiert. Dabei sind die Fronten verhärtet: Befürworter sehen sie als elementare Erlösquelle, Gegner dagegen als Wettbewerbsverletzung und ungerechtfertigte Preisabsprachen. Aus Sicht des Autors braucht der Markt ein gemeinsames Interbankenentgelt, andererseits muss auch eine Gebühr von null nicht zwangsläufig den Ruin für die Banken bedeuten. Betroffen sind die Kunden, die mit höheren Kosten konfrontiert werden.

Sepa: Herausforderungen und Chancen für deutsche Banken im Firmenkundengeschäft

In: Zeitschrift für das gesamte Kreditwesen 17 vom 01.09.2009, Seite 841

Category: Publications in journals

Abstract

Die (weiterhin steigende) Zahl an Insolvenzen zeigt, dass ein gutes Liquiditätsmanagement insbesondere während, aber auch nach Krisensituationen gerade für kleine und mittelgroße Unternehmen existenzbestimmend sein kann. Deshalb ist es nahe liegend, dass der Autor nicht zuletzt in der Verkürzung des Cash-to-Cash-Cycles eines der größten Mehrwertpotenziale im Zahlungsverkehr sieht: Nur wer die elektronische Rechnung anbietet, wird künftig seinen Hausbankstatus halten können. Seine Handlungsempfehlung ist daher eindeutig: Die Banken müssen sich auch mit Blick auf internationale Wettbewerber je nach Zielgruppe nur noch entscheiden, ob sie entsprechende Basisdienstleistungen einkaufen oder selbst entwickeln wollen.

Strukturwandel der Wertschöpfung im Bankgeschäft

In: Verlag Dr. Kovac; Hamburg

Category: Dissertation thesis [Find it]

Abstract

Die Wertschöpfung im Bankgeschäft ist einem drastischen Wandel unterworfen. In der Branche sind daher verschiedene strategische Ansätze und Entwicklungen zu beobachten. Hierzu zählen insbesondere ein Aufbrechen der Wertschöpfungskette und ein Wandel in der Rolle des Finanzintermediärs, Modifikationen der internen Prozesse und eine zunehmende Vernetzung in der Wertschöpfung. Diese Buch greift daher diese strategischen Entwicklungen in vier Beiträgen auf: Der erste Beitrag untersucht die Finanzintermediation zwischen Kreditnehmern und -gebern auf Peer-to-Peer-Lending-Plattformen mit besonderer Berücksichtigung der Bildung von Gruppen. Der zweite Beitrag entwickelt und validiert ein Modell zur Gestaltung und Messung interner Prozesse für das Customer-Relationship-Management (CRM). Im dritten Beitrag wird der Einsatz von Selbstbedienungs-Technologie im Filialgeschäft als Teil interner Vertriebsprozesse analysiert. Dabei wird der Einfluss von Persönlichkeitseigenschaften des Kunden und Charakteristika der Kundenbeziehung auf die Adoptions­entscheidung untersucht. Schließlich befasst sich der vierte Beitrag mit den Netzwerkstrukturen von Konsortialbanken bei Neuemissionen (IPOs) und zeigt deren Einfluss auf den Emissionserfolg.

Migration and the Retail Banking Industry - An Examination of Immigrants´ Bank Nationality Choice in Germany

In: European Journal of Finance (forthcoming)

Category: Publications in journals [Find it]

Abstract

We study the choice of bank nationality by foreign-born retail banking customers in the context of bank globalization. We argue theoretically that banks enter foreign markets to follow their non-corporate customers and thereby are able to exploit competitive advantages over domestic banks. Using detailed survey data on more than 1000 Turkish immigrants in Germany, we find that product differentiation explains the choice of a home nation bank and that ethnic origin in itself provides the strongest comparative advantage for foreign banks. We find evidence for a persistent 'home-bias' of customers with an immigration background even with increasing integration into the host country's culture. This result may be surprising given that a systematic difference in the choice of bank nationality should not be observable with more integrated immigrants. Our results contribute to the existing economic research on multinational bank expansion by providing insights into bank globalization as an accompaniment to labor market internationalization.

Towards a Service Governance Framework for the Internet of Services

In: Proceedings of the 17th European Conference on Information Systems, ECIS 2009

Category: Proceedings

Abstract

Companies nowadays face constantly changing market conditions, new competitive threats, and new legal regulations. Service-oriented Architectures (SOA) provide a promising way to address these challenges at the level of the company’s IT infrastructure. The paradigm of the Internet of Services envisions trade on a global service-enabled internet. Governance frameworks have been introduced to guideline an enterprise’s organisation and IT and ensure smooth operations. More specifically, IT Governance and recently SOA Governance have been established. The basic structure of IT governance frameworks is applicable to SOA. However, they lack functionality or applicability concerning SOA-specific challenges. Current approaches that focus mere SOA Governance lack framework scope. The issue aggravates taking into account the current shift to a marketplace-like Internet of Services. We identify these issues and provide initial insights on building blocks for a Service Governance Framework that enables operations for companies in a brokered service network. We discuss service lifecycle phases, stakeholder roles, and management processes taking into consideration existing frameworks such as ITIL and CObIT as well as industry-specific approaches from companies such as SAP, Oracle, and HP.

Governance of a Service-Oriented Architecture for Environmental and Public Security

In: Information Technologies in Environmental Engineering, ITEE 2009 - Fourth International ICSC Symposium; Springer, Berlin Heidelberg New York

Category: Proceedings

Abstract

Research for the application of technical support in environmental projects has grown rapidly due to the progress of sensor network systems and the large, scalable IT infrastructures that can unify and expand them. There are numerous attempts to make use of new technologies in order to serve environmental purposes. The research presented in this paper focuses on critical aspects of the core infrastructure of a project that aims to serve these purposes as well. The nature of the actions that must be taken against environmental disasters, which are our target use cases, dictate that extended, cross-organizational information and communication systems are engaged. In order to integrate information from different sources and process heterogeneous services, the IT infrastructure is based on the paradigm of Service-Oriented Architectures (SOA). However, the distributed and often very large nature of an SOA leads to a need for governance mechanisms. We present an SOA governance approach targeted to serve the purposes of large-scale distributed IT landscapes for environmental and public security.

Qualitative and Quantitative Aspects of Cooperation Mechanisms for Monitoring in Service-oriented Architectures

In: Proceedings of the Third IEEE International Conference on Digital Ecosystems and Technologies (IEEE DEST 2009)

Category: Proceedings

Abstract

Cooperation mechanisms for agents monitoring service-based workflows are a means to address the increasing complexity of modern enterprise architectures. These mechanisms are inspired by existing biological mechanisms and extend an existing decentralized monitoring architecture in order to handle deviations from Service Level Agreements autono-mously. As the core cooperation mechanisms have been subject of our previous work and have been described in detail earlier, we present now an evaluation of our concepts regarding both effectiveness and efficiency, based on an implemented proto-type.

Applied Service Engineering for Single Services and Corresponding Service Landscapes

In: 15th Americas Conference on Information Systems (AMCIS 2009); San Francisco, CA, USA

Category: Proceedings

Abstract

Building reusable and autonomous services that possess the proper degree of granularity is critical for the success of a service-oriented architecture (SOA), especially for large and heterogeneous IT landscapes. While there are a number of approaches to service engineering, most of these approaches are designed with a special purpose or project context in mind. This paper presents a pragmatic approach to service engineering that can be applied in scenarios where it is particularly necessary to identify service interfaces with the right granularity. The approach is based on a comparison of service engineering methodologies with special regard for their ability to connect different levels of an SOA. We apply concepts from this approach to build single services and their service landscapes. We also suggest the utilization of service inventory techniques to evaluate and assess the outcome of the proposed service engineering methodology.

The Role of IT/Business Alignment for Achieving SOA Business Value – Proposing a Research Model

In: Proceedings of the 15th Americas Conference on Information Systems (AMCIS 2009); San Francisco, USA

Category: Proceedings

Abstract

What is the interplay between IT/Business alignment and Service-oriented Architecture (SOA) regarding the achievement of business value in terms of business flexibility? This paper introduces a conceptual model that derives propositions about how IT/Business alignment, IT flexibility, and business flexibility are interrelated and how SOA and alignment interact in order to increase business flexibility. We apply and integrate well-known multi-dimensional concepts of both IT/Business alignment (in terms of strategic alignment, structural alignment, and social alignment) and IT flexibility (technical and non-technical IT flexibility) and map the conceptual components of SOA (architectural and the governance dimension) to this resulting model. This conceptualization will allow for more profoundly structured research on how SOA contributes to business value.

An empirical evaluation of the impact of process standardization on process performance and flexibility

In: Proceedings of the 15th Americas Conference on Information Systems (AMCIS 2009); San Francisco, USA

Category: Proceedings

Abstract

This paper argues that business process standardization, as part of BPM activities, is an effective way to improve business process flexibility and performance. We develop and empirically evaluate a theoretical model of the differential impact of business process homogenization and optimization on business process flexibility and performance. The analysis based on data from 85 large firms shows a strong and highly significant influence of process standardization on business process flexibility and performance. This paper is among the first to propose a research model and empirical operationalization to analyze the twofold impact of process standardization on business process flexibility and performance. For practitioners the paper provides actionable recommendations on how to apply the findings to their management context.

Impact of Service-oriented Architectures (SOA) on Business Process Standardization – Proposing a Research Model

In: Proceedings of the 17th European Conference on Information Systems (ECIS); Verona, Italy

Category: Proceedings

Abstract

What is the impact of a Service-oriented Architecture (SOA) on the efficiency and effectiveness of business process standardization (BPS)? The contribution of this paper is the development of a research model around the impact of SOA on BPS in terms of achieving fundamental efficiency and flexibility potentials while covering both the business layer and the IT layer of the firm. Drawing on an accepted and widespread enterprise architecture model, we derive propositions that explain why and how SOA’s characteristics help to standardize business processes and how the interplay between SOA and BPS leads to an increased overall business value. Additional moderator arguments, such as the level of service granularity, the centrality of SOA governance, or Business IT alignment, are added to the research model as critical success factors of achieving business value of SOA.

Risks and Benefits of Business Process Outsourcing: A Study of Transaction Services in the German Banking Industry

In: Information & Management 46(4), 249-257

Category: Publications in scientific journals [Find it]

Abstract

We developed a model of the adoption of business process outsourcing (BPO) based on risk-benefit analysis. The model was tested in the German Banking Industry in four areas of transaction processing. Our results showed that, in general, perceived BPO benefits have a substantially stronger impact on intention to increase the level of BPO than perceived risks. However, the experience that banks have with the BPO process, [whether already decided on BPO (Pro), still in the pre-decision phase (Neutral), or opted against BPO (Contra)], moderated the impact of factors affecting the perceived risks and benefits of BPO. Banks that opted for BPO were mostly driven by a desire to focus on their core business while considering financial risks. Banks in the neutral position had the most balanced view of risks and benefits, mainly financial and performance ones, and also focusing on the core business and increased business process performance. Those banks that decided against BPO mostly focused on benefits though the perceived risks were mostly formed by strategic and performance risks rather than financial ones. The results point out the path dependencies of the BPO decision.

Emergence of Financial Intermediaries on Electronic Markets: The Case of Online P2P Lending

In: Business Research 2(1), 39-65

Category: Publications in scientific journals [Find it]

Abstract

We analyze the role of intermediaries in electronic markets using detailed data of more than 14,000 originated loans on an electronic P2P (peer-to-peer) lending platform. On such an electronic credit market lenders bid to supply a private loan. Screening of potential borrowers and the monitoring of loan repayment can be delegated to designated group leaders. We find that these market participants act as financial intermediaries and significantly improve borrowers' credit conditions, predominantly for borrowers with less attractive risk characteristics. As suggested by traditional intermediation theory, the intermediary creates value by reducing information asymmetries between borrowers and lenders. Our findings are robust to self-selection and characteristics of the financial transactions, and may be surprising given the replacement of a bank as the traditional intermediary by an electronic marketplace.

Sports Forecasting: A Comparison of the Forecast Accuracy of Prediction Markets, Betting Odds and Tipsters

In: Journal of Forecasting, Vol. 28, 55-72

Category: Publications in scientific journals [Find it]

Abstract

This article compares the forecast accuracy of different methods, namely prediction markets, tipsters and betting odds, and assesses the ability of prediction markets and tipsters to generate profi ts systematically in a betting market. We present the results of an empirical study that uses data from 678–837 games of three seasons of the German premier soccer league. Prediction markets and betting odds perform equally well in terms of forecasting accuracy, but both methods strongly outperform tipsters. A weighting-based combination of the forecasts of these methods leads to a slightly higher forecast accuracy, whereas a rule-based combination improves forecast accuracy substantially. However, none of the forecasts leads to systematic monetary gains in betting markets because of the high fees (25%) charged by the state-owned bookmaker in Germany. Lower fees (e.g., approximately 12% or 0%) would provide systematic profi ts if punters exploited the information from prediction markets and bet only on a selected number of games.

Identification of Lead Users for Consumer Products via Virtual Stock Markets

In: Journal of Product Innovation Management, 26(3), S. 322-335

Category: Publications in scientific journals [Find it]

Abstract

Newly launched products in the consumer goods and services markets show high failure rates. In order to reduce the failure rates, companies can integrate innovative and knowledgeable customers, the so called ‘lead users’, into the new product development process. However, the detection of such lead users is difficult, especially in consumer product markets with very large customer bases. A new and potentially valuable approach towards the identification of lead users involves the use of Virtual Stock Markets, which have been proposed and applied for political and business forecasting, but not for the identification of experts such as lead users. The basic concept of Virtual Stock Markets is bringing a group of participants together via the Internet and allowing them to trade shares of virtual stocks. These stocks represent a bet on the outcome of future market situations and their value depends on the realization of these market situations. In this process, a Virtual Stock Market elicits and aggregates the assessments of its participants concerning future market developments. Virtual Stock Markets might also serve as a feasible instrument to filter out lead users, primarily for the following two reasons. Firstly, a "self-selection effect" might occur because sophisticated consumers with a higher involvement in the product of interest decide to participate in Virtual Stock Markets. Secondly, a "performance effect" is likely to arise because well-performing participants in Virtual Stock Markets show a better understanding of the market than their (already self-selected) fellow participants. So far, only limited information exists about these two effects and their relation to lead user characteristics. The goal of this article is to analyze the feasibility of Virtual Stock Markets for the identification of lead users. The results of our empirical study show that Virtual Stock Markets can be an effective instrument to identify lead users in consumer products markets. Furthermore, the results show that not all lead users perform well in Virtual Stock Markets. Hence, Virtual Stock Markets allow identifying lead users with superior abilities to forecast market success.

Antecedents and Consequences of the Online Channel Performance

Category: Publications in scientific journals [Find it]

Abstract

Internet distribution channels may be either advantageous or detrimental for a company. Therefore, this study analyzes their performance, antecedents, and effect on company performance. Using survey data from multichannel retailers and structural equation model methodology, the authors show that Internet channel performance contributes to both financial and strategic company performance, with a greater effect on the latter. Similar and uncoordinated channels hinder Internet channel performance, but experience with direct channels and channel power are not required to pursue an Internet channel successfully. Customer migration and managerial commitment to the Internet channel have strong positive influences on financial performance. Overall, the results encourage the adoption and development of Internet channels.

Abstract

We develop a model for firms with contractual customer relationships to link customer metrics (such as customer cash flow, number of customers, and customer retention) to customer equity and shareholder value. This model allows us to calculate a firm's shareholder value and to evaluate the effect of changes in customer metrics on shareholder value. Our empirical studies, our analytical solutions and our simulation study show that customer retention has by far the greatest impact on shareholder value. Furthermore, we propose a ratio of customer equity to shareholder value to identify firms in which changes in customer metrics have a particularly large impact on shareholder value. Our findings allow researchers and managers who analyze the impact of marketing investments on customer metrics to assess their results in terms of shareholder value and to evaluate firms by using customer metrics.

Knowledge Transfer Processes in IT Outsourcing Relationships and their Impact on Shared Knowledge and Outsourcing Performance

In: International Journal of Information Management (IJIM), Volume 29, Issue 5

Category: Publications in scientific journals [Find it]

Abstract

What is the impact of specific knowledge transfer processes on the level of shared knowledge and, in turn, on outsourcing performance in outsourcing relationships? Drawing on a series of case studies covering IT providers and banks, we investigate several applied knowledge transfer processes dedicated to the transfer of explicit or tacit knowledge between outsourcing banks and their providers. We examine the differential influence of various types of knowledge transfer on shared knowledge between the parties and on the resulting outsourcing performance. Results depict the differential impact of various knowledge transfer processes dedicated to the transfer of explicit, or tacit knowledge, respectively, on the development of shared knowledge. Interestingly, the combination of both knowledge transfer processes dedicated to the transfer of explicit knowledge and those dedicated to the transfer of tacit knowledge proves to be most effective. Furthermore the results indicate that high levels of shared knowledge positively influence outsourcing performance. In addition to previous literature, we found transfer processes for explicit knowledge in an outsourcing context to consist of two dimensions: The content dimension, primarily focused on in literature, and the sender-receiver dimension of transfer processes which are rarely addressed in outsourcing literature. The content dimension embraces mechanisms such as trainings, SLAs and standards that define how content has to be interpreted, whereas the sender-receiver dimension of transfer processes of explicit knowledge defines explicit, documented interaction structures between parties.

Abstract

This paper suggests to extend the view that strateg-ic alignment is a core IT governance issue and post-ulates that considering operational alignment as well offers more precise insights into how governance mechanisms influence business process performance. Theoretically combining findings from IT value, IT business alignment and IT governance research, we show the tantamount role of top executive support and operational alignment from a governance perspective. Empirical data from 82 firms show, among others, that the impact of IT governance mechanisms on success is mediated by strategic and operational alignment.

The Role of Process Standardization in Achieving IT Business Value

In: Hawaii International Conference on System Sciences (HICSS-42); Big Island, Hawaii, USA

Category: Proceedings

Abstract

We empirically investigate the interplay and impact of process standardization and IT intensity on business process performance in terms of efficiency, quality, control, and processing time. To this aim we surveyed the retail advisory operations of Germany’s largest banks. We find that standardization enhances efficiency, quality and control of the advisory process. Additionally, IT intensity on its own shows positive effects on efficiency and quality as well, while it leads to more customer facing time needed for a single customer. Also, the interaction effect with process standardization is relevant. We conclude that IT creates business value through facilitating process standardization and process control. Our results strongly indicate that managers have to look carefully at the type of the processes before standardizing it.

Abstract

A competitive implementation of customer relationship management (CRM) in retail banking requires business processes aligned to the value contribution. The objective of this paper is to derive a reference process on macro-level from industry best practice and validate its applicability in a survey. Furthermore, we introduce a new method for evaluating existing business process implementations with respect to the business value, as measured by the value of the customer base as relevant overall key performance measure. Comparing the individual company process and the reference process, in-house and external experts can evaluate the gaps by using the decision calculus method. This allows a clear recommendation on the prioritization of potential process modifications and quantifies their effect in terms of business value.

Abstract

Purpose – The purpose of this paper is to explain the use of online communities for information seeking in the financial products purchasing process and identify relevant usage antecedents.

Design/methodology/approach – A theoretical framework is proposed based on the three dimensions community, environment and user characteristics. Subsequently, a representative survey among German consumers is described, illustrating the value of the framework.

Findings – The study validates the framework to analyze online community usage and identifies financial knowledge and employment status as main drivers of financial community usage among user characteristic.

Research limitations/implications – The present study was carried out in only one country, but provides a starting point for more international research.

Practical implications – The results identify community users as an interesting clientele, which should be considered in financial services providers' online strategy development, especially by encouraging word-of-mouth communication. Usage drivers should be considered in web site development to prevent churn. Providers of communities should be concerned about system usability, but also especially take measures to boost the social aspects of community experience.

Originality/value – The study is the first to explain online community usage in the economically highly relevant pre-purchase stage for financial services.
