We show that multi-bank loan pools improve the risk-return profile of banks’ loan business. Banks write simple contracts on the proceeds from pooled loan portfolios, taking into account the free-rider problems in joint loan production. Thus, banks benefit greatly from diversifying credit risk while limiting the efficiency loss due to adverse incentives. We present calibration results that the formation of loan pools reduce the volatility in default rates, proxying for credit risk, of participating banks’ loan portfolios by roughly 70% in our sample. Under reasonable assumptions, the gain in return on equity (in certainty equivalent terms) is around 20 basis points annually.
Microeconomic modeling of investors behavior in financial markets and its results crucially depends on assumptions about the mathematical shape of the underlying preference functions as well as their parameterizations. With the purpose to shed some light on the question, which preferences towards risky financial outcomes prevail in stock markets, we adopted and applied a maximum likelihood approach from the field of experimental economics on a randomly selected dataset of 656 private investors of a large German discount brokerage firm. According to our analysis we find evidence that the majority of these clients follow trading pattern in accordance with Prospect Theory (Kahneman and Tversky (1979)). We also find that observable sociodemographic and personal characteristics such as gender or age don't seem to correlate with specific preference types. With respect to the overall impact of preferences on trading behavior, we find a moderate impact of preferences on trading decisions of individual investors. A classification of investors according to various utility types reveals that the strength of the impact of preferences on an investors' rading behavior is not connected to most personal characteristics, but seems to be related to round-trip length.
Shortcomings revealed by experimental and theoretical researchers such as Allais (1953), Rabin (2000) and Rabin and Thaler (2001) that put the classical expected utility paradigm von Neumann and Morgenstern (1947) into question, led to the proposition of alternative and generalized utility functions, that intend to improve descriptive accuracy. The perhaps best known among those alternative preference theories, that has attracted much popularity among economists, is the so called Prospect Theory by Kahneman and Tversky (1979) and Tversky and Kahneman (1992). Its distinctive features, governed by its set of risk parameters such as risk sensitivity, loss aversion and decision weights, stimulated a series of economic and financial models that build on the previously estimated parameter values by Tversky and Kahneman (1992) to analyze and explain various empirical phenomena for which expected utility doesn't seem to offer a satisfying rationale. In this paper, after providing a brief overview of the relevant literature, we take a closer look at one of those papers, the trading model of Vlcek and Hens (2011) and analyze its implications on Prospect Theory parameters using an adopted maximum likelihood approach for a dataset of 656 individual investors from a large German discount brokerage firm. We find evidence that investors in our dataset are moderately averse to large losses and display high risk sensitivity, supporting the main assumptions of Prospect Theory.
Does BPO pay off at the firm-level? Although there are several studies which analyze the potential benefits of BPO, there is a virtual absence of research papers on BPO outcomes. Based on an analysis of 137 Business process outsourcing (BPO) ventures at 254 German banks in a period between 1994 and 2005, we found that the outsourcer's financial performance in terms of profitability and cost efficiency was increased significantly compared to industry peers without BPO. The increase stems not from workforce reductions but rather from increased employee productivity. Further, we show how BPO governance ensures BPO success: individually negotiated outsourcing contracts help to improve cost efficiency and profitability measures. Relational governance based on trust has only positive effects on profitability.

This paper investigates the impact of IT standardization on bank performance based on a panel of 457 German savings banks over the period from 1996 to 2006. We measure IT standardization as the fraction of IT expenses for centralized services over banks' total IT expenses. Bank efficiency, in turn, is measured by traditional accounting performance indicators as well as by cost and profit efficiencies that are estimated by a stochastic frontier approach. Our results suggest that IT standardization is conducive to cost efficiency. The relation is positive and robust for small and medium-sized banks but vanishes for very large banks. Furthermore, our study confirms the often cited computer paradox by showing that total IT expenditures negatively impact cost efficiency and have no influence on bank profits. To the best of our knowledge, this paper is first to empirically explore whether IT standardization enhances efficiency by employing genuine data of banks' IT expenditures.

Since the beginning of the 1990s, it has been widely expected that the implementation of the European Single Market would lead to a rapid convergence of Europe’s financial systems. In the present paper we will show that at least in the period prior to the introduction of the common currency this expected convergence did not materialise. Our empirical studies on the significance of various institutions within the financial sectors, on the financing patterns of firms in various countries and on the predominant mechanisms of corporate governance, which are summarised and placed in a broader context in this paper, point to few, if any, signs of a convergence at a fundamental or structural level between the German, British and French financial systems. The German financial system continues to appear to be bank-dominated, while the British system still appears to be capital market-dominated. During the period covered by the research, i.e. 1980 – 1998, the French system underwent the most far-reaching changes, and today it is difficult to classify. In our opinion, these findings can be attributed to the effects of strong path dependencies, which are in turn an outgrowth of relationships of complementarity between the individual system components. Projecting what we have observed into the future, the results of our research indicate that one of two alternative paths of development is most likely to materialise: either the differences between the national financial systems will persist, or – possibly as a result of systemic crises – one financial system type will become the dominant model internationally. And if this second path emerges, the Anglo-American, capital market-dominated system could turn out to be the “winner”, because it is better able to withstand and weather crises, but not necessarily because it is more efficient.
Wenn man untersuchen möchte, ob sich die Finanzsysteme verschiedener Länder im Verlauf der letzten Jahre aneinander angeglichen haben oder demnächst angleichen werden, braucht man ein Konzept zur Beschreibung von Finanzsystemen, durch das wesentliche Strukturen, deren Unterschiede und Veränderungen erkennbar werden, ohne dabei in "Systemgeschwafel" (D. Schneider) abzugleiten. Wir haben dafür das Konzept der Komplementarität als nützlich identifiziert. Der Beitrag stellt dieses Konzept vor und soll und seine Eignung belegen. Letztlich geht es dabei auch um die Frage, ob reale Finanzsysteme konsistente Systeme mit komplementären Elementen darstellen. Nach der Vorstellung der formalen Konzepte der Komplementarität und der Konsistenz wird "das Finanzsystem" auf seine Komple mentarität untersucht. Dazu wird ein Finanzsystem aus der Sicht von Unternehmen des nichtfinanziellen Sektors als ein System gekennzeichnet, das aus drei Teilsystemen besteht. Das erste Teilsystem ist das Finanzierungssystem einschließlich Finanzsektor und Mustern der Unternehmensfinanzierung, das zweite das Corporate Governance-System und das dritte das Unternehmens-Strategie-System. Für alle drei Teilsysteme wird – allgemein und mit Bezug auf die Finanzsysteme Deutschlands, Japans und der USA - gezeigt, inwieweit die Elemente der betreffenden Teilsysteme untereinander komplementär sind, und geprüft, ob sie in ihren Ausprägungen auch konsistent sind, d.h. wirklich "zueinander passen". Untersucht wird auch die Komplementarität und Konsistenz zwischen den Teilsystemen selbst. Der Beitrag endet mit Überlegungen über die Anwendung des Komplementaritätskonzepts. Dass ein Finanzsystem die Eigenschaft der Komplementarität aufweist, hat nicht nur weitreichende Implikationen für die Methodik der Analyse von Finanzsystemen, sondern auch für die Vorhersehbarkeit der Entwicklung von Finanzsystemen und damit für die Wahrscheinlichkeit einer Konvergenz von Finanzsystemen, für deren Effizienzeigenschaften und für die Möglichkeiten, Finanzsysteme durch gestaltende Eingriffe zu verbessern.
A widely recognized paper by Colin Mayer (1988) has led to a profound revision of academic thinking about financing patterns of corporations in different countries. Using flow-of-funds data instead of balance sheet data, Mayer and others who followed his lead found that internal financing is the dominant mode of financing in all countries, that therefore financial patterns do not differ very much between countries and that those differences which still seem to exist are not at all consistent with the common conviction that financial systems can be classified as being either bank-based or capital market-based. This leads to a puzzle insofar as it calls into question the empirical foundation of the widely held belief that there is a correspondence between the financing patterns of corporations on the one side, and the structure of the financial sector and the prevailing corporate governance system in a given country on the other side. The present paper addresses this puzzle on a methodological and an empirical basis. It starts by demonstrating that the surprising empirical results found by Mayer et al. are due to a hidden assumption underlying their methodology. It then derives an alternative method of measuring financing patterns, which also uses flow-of-funds data, but avoids the questionable assumption. This measurement concept is then applied to patterns of corporate financing in Germany, Japan and the United States. The empirical results are very much in line with the commonly held belief prior to Mayer’s influential contribution and indicate that the financial systems of the three countries do indeed differ from one another in a substantial way.
This paper investigates the magnitude and the main determinants of share price reactions to buy-back announcements of German corporations. Based on a sample of 224 announcements from the period May 1998 to April 2003 we find average cumulative abnormal returns around -7.5% for the thirty days preceding the announcement and around +7.0 % for the ten days following the announcement. We regress postannouncement abnormal returns with multiple firm characteristics and provide evidence which supports the undervaluation signaling hypothesis but not the excess cash hypothesis. In extending prior empirical work, we also analyze price effects from an initial statement by management that it intends to seek shareholder approval for a buy-back plan. Observed cumulative abnormal returns on this initial date are in excess of 5% implying a total average price effect between 12% and 15% from implementing a buy-back plan. We conjecture that the German regulatory environment is the main reason why market variations to buy-back announcements are much stronger in Germany than in other countries and conclude that initial statements by managers to seek shareholders’ approval for a buy-back plan should also be subject to legal ad-hoc disclosure requirements.

Individual financial systems can be understood as very specific configurations of certain key elements. Often these configurations remain unchanged for decades. We hypothesize that there is a specific relationship between key elements, namely that of complementarity. Thus, complementarity seems to be an essential feature of financial systems. Intuitively speaking, complementarity exists if the elements of a (financial) system reinforce each other in terms of contributing to the functioning of the system. It is the purpose of this paper to provide an analytical clarification of the concept of complementarity. This is done by modeling financial systems as combinations of four elements: firm-specific human capital of an entrepreneur, the ability of a bank to restructure the borrower's firm in the case of distress, the possibility to appropriate private benefits from running the firm, and the bankruptcy law. A specific configuration of these elements constitutes one financial system. The bankruptcy law and the potential private benefits are treated as exogenous. They determine the bargaining power of the contracting parties in the case that recontracting occurs. In a two-stage game, the optimal values for the other elements are determined by the agents individually - by investing in human capital and restructuring skills, respectively - and jointly by writing, executing and possibly renegotiating a financing contract for the firm. The paper discusses the equilibria for different types of bankruptcy law and demonstrates that equilibria exhibit the sought-after feature of complementarity. Three particularly significant equilibria correspond to stylized accounts of the British, German and the US-American financial system, respectively.
The paper presents an empirical analysis of the alledged transformation of the financial systems in the three major European economies, France, Germany and the UK. Based on a unified data set developed on the basis of national accounts statistics, and employing a new and consistent method of measurement, the following questions are addressed: Is there a common pattern of structural change; do banks lose importance in the process of change; and are the three financial systems becoming more similar? We find that there is neither a general trend towards disintermediation, nor towards a transformation from bank-based to capital market-based financial systems, nor for a loss of importance of banks. Only in the case of France strong signs of transformation as well as signs of a general decline in the role of banks could be found. Thus the three financial systems also do not seem to become more similar. However, there is also a common pattern of change: the intermediation chains are lengthening in all three countries. Nonbank financial intermediaries are taking over a more important role as mobilizers of capital from the non-financial sectors. In combination with the trend towards securitization of bank liabilites, this change increases the funding costs of banks and may put banks under pressure. In the case of France, this change is so pronounced that it might even threaten the stability of the financial system.
Initiated by the seminal work of Diamond/Dybvig (1983) and Diamond (1984), advances in the theory of financial intermediation have sharpened our understanding of the theoretical foundations of banks as special financial institutions. What makes them "unique" is the combination of accepting deposits and issuing loans. However, in recent years the notion of "disintermediation" has gained tremendous popularity, especially among American observers. These observers argue that deregulation, globalisation and advances in information technology have been eroding the role of banks as intermediaries and thus their alleged uniqueness. It is even assumed that ever more efficiently organised capital markets and specialised financial institutions that take advantage of these markets, such as mutual funds or finance companies, will lead to the demise of banks. Using a novel measurement concept based on intermediation and securitisation ratios, the present article provides evidence which shows that banking disintermediation is indeed a reality for the US financial system. This seems to indicate that American banks are not all that "unique"; they can be replaced to a considerable extent. Moreover, many observers seem to believe that what has happened in the US reflects a universal trend. However, empirical results reported in this paper indicate that such a trend has not manifested itself in other financial systems, and in particular, not in Germany or Japan. Evidence on the enormous structural differences between financial systems and the lack of unequivocal signs of convergence render any inferences from the American experience to other financial systems very problematic.
This paper is a draft for the chapter German banks and banking structure of the forthcoming book The German financial system . As such, the paper starts out with a description of past and present structural features of the German banking industry. Given the presented empirical evidence it then argues that great care has to be taken when generalising structural trends from one financial system to another. Whilst conventio nal commercial banking is clearly in decline in the US, it is far from clear whether the dominance of banks in the German financial system has been significantly eroded over the last decades. We interpret the immense stability in intermediation ratios and financing patterns of firms between 1970 and 2000 as strong evidence for our view that the way in which and the extent to which German banks fulfil the central functions for the financial system are still consistent with the overall logic of the German financial system. In spite of the current dire business environment for financial intermediaries we do not expect the German financial system and its banking industry as an integral part of this system to converge to the institutional arrangements typical for a market-oriented financial system.

This paper shows that abnormal stock price returns around open market repurchase announcements are about four times higher in Germany than in the US (12% versus 3%). We hypothesize that this observation can be explained by country differences in repurchase regulation. Our empirical evidence indicates that German managers primarily buy back shares to signal an undervaluation of their firm. We demonstrate that the stringent repurchase process prescribed by German law attributes a higher credibility to such a signal than lax US regulations and thereby corroborate our hypothesis.
This paper investigates the magnitude and the main determinants of share price reactions to buy-back announcements of German corporations. For our comprehensive sample of 224 announcements that took place between May 1998 and April 2003 we find average cumulative abnormal returns around -7.5% for the thirty days preceding the announcement and around +7.0 % for the ten days following the announcement. We regress post-announcement abnormal returns with multiple firm characteristics and provide evidence which supports the undervaluation signaling hypothesis but not the excess cash hypothesis or the tax-efficiency hypothesis. In extending prior empirical work, we also analyze price effects from initial statements of firms that they intend to seek shareholder approval for a buy-back plan. Observed cumulative abnormal returns on this initial date are in excess of 5% implying a total average price effect between 12% and 15% from implementing a buy-back plan. We conjecture that the German regulatory environment is the main reason why market variations to buy-back announcements are much stronger in Germany than in other countries and conclude that initial statements by managers to seek shareholders’ approval for a buy-back plan should also be subject to legal ad-hoc disclosure requirements.
This paper is a draft for the chapter "German banks and banking structure" of the forthcoming book "The German financial system" edited by J.P. Krahnen and R.H. Schmidt (Oxford University Press). As such, the paper starts out with a description of past and present structural features of the German banking industry. Given the presented empirical evidence it then argues that great care has to be taken when generalising structural trends from one financial system to another. Whilst conventional commercial banking is clearly in decline in the US, it is far from clear whether the dominance of banks in the German financial system has been significantly eroded over the last decades. We interpret the immense stability in intermediation ratios and financing patterns of firms between 1970 and 2000 as strong evidence for our view that the way in which and the extent to which German banks fulfil the central functions for the financial system are still consistent with the overall logic of the German financial system. In spite of the current dire business environment for financial intermediaries we do not expect the German financial system and its banking industry as an integral part of this system to converge to the institutional arrangements typical for a market-oriented financial system.
This paper starts out by pointing out the challenges and weaknesses which the German banking systems faces according to the prevailing views among national and international observers. These challenges include a generalproblem of profitability and, possibly as its main reason, the strong role of public banks. These concerns raise the questions whether the facts support this assessment of a general profitability problem and whether there are reasons to expect a fundamental or structural transformation of the German banking system. The paper contains four sections. The first one presents the evidence concerning the profitability problem in a comparative, international perspective. The second section presents information about the so-called three-pillar system of German banking. What might be surprising in this context is that the group of pub lic banks is not only the largest segment of the German banking system, but that the primary savings banks also are its financially most successful part. The German banking system is highly fragmented. This fact suggests to discuss past, present and possible future consolidations in the banking system in the third section. The authors provide evidence to the effect that within- group consolidation has been going on at a rapid pace in the public and the cooperative banking groups in recent years and that this development has not yet come to an end, while within-group consolidation among the large private banks, consolidation across group boundaries at a national level and cross-border or international consolidation has so far only happened at a limited scale, and do not appear to gain momentum in the near future. In the last section, the authors develop their explanation for the fact that large-scale and cross border consolidation has so far not materialized to any great extent. Drawing on the concept of complementarity, they argue that it would be difficult to expect these kinds of mergers and acquisitions happening within a financial system which is itself surprisingly stable, or, as one cal also call it, resistant to change.
A widely recognized paper by Colin Mayer (1988) has led to a profound revision of academic thinking about financing patterns of corporations in different countries.

The present paper addresses this puzzle on a methodological and an empirical basis. It starts by comparing and analyzing various ways of measuring financial structure and financing patterns and by demonstrating that the surprising empirical results found by studies that relied on net flows are due to a hidden assumption. It then derives an alternative method of measuring financing patterns, which also uses flow-of-funds data, but avoids the questionable assumption. This measurement concept is then applied to patterns of corporate financing in Germany, Japan and the United States. The empirical results, which use an estimation technique for determining gross flows of funds in those cases in which empirical data are not available, are very much in line with the commonly held belief prior to Mayer’s influential contribution and indicate that the financial systems of the three countries do indeed differ from one another in a substantial way, and moreover in a way which is largely in line with the general view of the differences between the financial systems of the countries covered in the present paper.
The German corporate governance system has long been cited as the standard example of an insider-controlled and stakeholder-oriented system. We argue that despite important reforms and substantial changes of individual elements of the German corporate governance system the main characteristics of the traditional German system as a whole are still in place. However, in our opinion the changing role of the big universal banks in the governance undermines the stability of the corporate governance system in Germany. Therefore a breakdown of the traditional system leading to a control vacuum or a fundamental change to a capital market-based system could be in the offing.
Die durch jahrzehntelange Planwirtschaft geprägten Strukturen sind in Russland noch fest verwurzelt. Dementsprechend ist das Bankensystem auch zwölf Jahre nach dem Ende des kommunistischen Regimes unterentwickelt. Die markantesten Merkmale der Finanzwirtschaft sind die ungewöhnliche Größenstruktur der Banken; deren Schwierigkeiten, die rapide zunehmende Zahl kleinster, kleiner und mittlerer Unternehmen mit Finanzdienstleistungen zu versorgen sowie die geringe Rolle ausländischer Banken. Überdies sind die weiterhin bestehenden Systemrisiken nicht zu unterschätzen.
We use minutes from 17,000 financial advisory sessions and corresponding client portfolio data to study how active client involvement affects advisor recommendations and portfolio outcomes. We find that advisors confronted with acquiescent clients stick to their standards and recommend expensive but well diversified mutual fund portfolios. However, if clients take an active role in the meetings, advisors deviate markedly from their standards, resulting in poorer portfolio diversification and lower Sharpe ratios. Our findings that advisors cater to client requests parallel the phenomenon of doctors prescribing antibiotics to insistent patients even if inappropriate, and imply that pandering diminishes the quality of advice.

Dieser Text fasst eine Studie zusammen, die für das Bundesministeriums für Ernährung, Landwirtschaft und Verbraucherschutz verfasst wurde und sich mit dem Kundennutzen von Anlageberatung auseinandersetzt. Das erhebliche Potenzial von interessenskongruenter Anlageberatung wird aufgezeigt und die aktuell geringe Leistungstransparenz im Markt kritisiert. Es wird empfohlen, ein standardisiertes Vokabular für Depotrisiken einzuführen und den Zugang aller Anleger zu leicht verständlichen und vergleichbaren Informationen zu historischem Depotrisiko und historischer Deporendite sicherzustellen. Die Studie fokussiert auf Wertpapierberatung und damit zuvorderst auf jene Teilmenge von Verbrauchern, die über Anlagevermögen verfügen. Die Grundideen zu Leistungstransparenz und standardisiertem Risikovokabular lassen sich jedoch auch z.B. auf den Alterssicherungsmarkt übertragen.
Vielfältige Einschnitte im Rentensystem haben die Bedeutung der privaten Altersvorsorge in den vergangenen Jahren massiv erhöht. Neben Immobilienbesitz, Lebensversicherungen und staatlich geförderten Programmen zur privaten Vorsorge hat sich inzwischen auch die eigenverantwortliche Altersvorsorge mit Wertpapierdepots etabliert, so dass die Anzahl privater Depots in den letzten 25 Jahren von 8,0 auf 27,9 Millionen gestiegen ist. Vor diesem Hintergrund ist die Frage von zentraler Bedeutung, wie gut Anleger ihr Geld investieren.
Cryptocurrencies have received growing attention from individuals, the media, and regulators. However, little is known about the investors whom these financial instruments attract. Using administrative data, we describe the investment behavior of individuals who invest in cryptocurrencies with structured retail products. We find that cryptocurrency investors are active traders, prone to investment biases, and hold risky portfolios. In line with attention effects and anticipatory utility, we find that the average cryptocurrency investor substantially increases log-in and trading activity after his or her first cryptocurrency purchase. Our results document which investors are more likely to adopt new financial products and help inform regulators about investors' vulnerability to cryptocurrency investments.
Manipulative communications touting stocks are common in capital markets around the world. Although the price distortions created by so-called “pump-and-dump” schemes are well known, little is known about the investors in these frauds. By examining 421 “pump-and-dump” schemes between 2002 and 2015 and a proprietary set of trading records for over 110,000 individual investors from a major German bank, we provide evidence on the participation rate, magnitude of the investments, losses, and the characteristics of the individuals who invest in such schemes. Our evidence suggests that participation is quite common and involves sizable losses, with nearly 6% of active investors participating in at least one “pump-and-dump” and an average loss of nearly 30%. Moreover, we identify several distinct types of investors, some of which should not be viewed as falling prey to these frauds. We also show that portfolio composition and past trading behavior can better explain participation in touted stocks than demographics. Our analysis offers insights into the challenges associated with designing effective investor protection against market manipulation.
Am 6. Februar 2013 hat die Bundesregierung den "Entwurf eines Gesetzes zur Abschirmung von Risiken und zur Planung der Sanierung und Abwicklung von Kreditinstituten und Finanzgruppen” veröffentlicht. Artikel 2 des Gesetzesentwurfs sieht vor bei systemrelevanten Finanzinstitutionen das Einlagen- und Kreditgeschäft vom Handelsgeschäft abzutrennen. Die Zielsetzung des Gesetzentwurfs, Kapitalkosten wieder in direkte Abhängigkeit des Risikos von Geschäftsfeldern zu setzen und eine Abwicklung zu erleichtern, die ohne den Einsatz von Steuermitteln gelingen kann, ist begrüßenswert. In seiner derzeitigen Ausgestaltung läuft der Gesetzesentwurf jedoch Gefahr, zwar symbolträchtig zu sein, aber in der Zielerreichung hinsichtlich Stabilität des Finanzmarktes und Schutz von Einlegern und Steuerzahlern hinter den Erwartungen zurückzubleiben.
Angesichts des kürzlich von der Bundesregierung verabschiedeten Konjunkturpakets, stellen sich die Autoren des Policy Letters die Frage, ob und inwieweit die angekündigte Mehrwertsteuersenkung sowie der Kinderbonus zur substantiellen Ankurbelung des Binnenkonsums führt. Aus den für das Haushaltskrisenbarometer erhobenen Daten zu Einkommensänderungen sowie Einkommens- und Kündigungserwartungen, können die Ökonomen keine zu erwartende Schwächung der Binnennachfrage ableiten. Der überwiegende Teil der deutschen Wohnbevölkerung scheint kurzfristig nicht davon auszugehen, finanzielle Einbußen aufgrund der Pandemie zu erleiden. Die Erwartungen hinsichtlich der künftigen Einkommensentwicklung haben sich gar über die letzten vier Umfragewellen graduell verbessert. Ferner kann dargelegt werden, dass weder die Konsum- noch die Sparneigung durch die Corona-Krise zum gegenwärtigen Zeitpunkt langfristig stark beeinflusst wird. So geben derzeit lediglich 10 Prozent der Befragten an, größere Anschaffungen angesichts der Pandemie vollständig gestrichen zu haben. Anfang April 2020 lag dieser Wert noch bei 16 Prozent. Die Befragten berichteten in 71 Prozent der Fälle ihre Konsumpläne und in 78 Prozent der Fälle ihre Sparverhalten nicht geändert zu haben. Im Lichte dieser Ergebnisse lassen sich Maßnahmen, die auf eine unspezifische Stimulierung der Binnennachfrage abzielen, nicht substantiell begründen und rechtfertigen.
Financial literacy affects wealth accumulation, and pension planning plays a key role in this relationship. In a large field experiment, we employ a digital pension aggregation tool to confront a treatment group with a simplified overview of their current pension claims across all pillars of the pension system. We combine survey and administrative bank data to measure the effects on actual saving behavior. Access to the tool decreases pension uncertainty for treated individuals. Average savings increase - especially for the financially less literate. We conclude that simplification of pension information can potentially reduce disparities in pension planning and savings behavior.
Zum ersten Mal wurde in Deutschland eine groß angelegte wissenschaftliche Studie zur Machbarkeit und zum Nutzen einer säulenübergreifenden Renteninformationsplattform durchgeführt, unter realen Bedingungen und mit mehreren tausend Teilnehmern. Die beiden zentralen Ergebnisse sind, dass ein elektronisches Rentencockpit auch in Deutschland technisch machbar ist und beträchtlichen individuellen Zusatznutzen für die Bürgerinnen und Bürger stiften würde. Die Langfristanalysen der Pilotstudie zeigen, dass selbst die einmalige Schaffung von Rententransparenz für viele Teilnehmer Anlass genug ist, ihren Rentenplan zu überdenken und sich aktiv mit ihrer Altersvorsorge auseinanderzusetzen und ihr Verhalten zu ändern. Teilnehmer mit Zugang zu einem elektronischen Rentencockpit fühlen sich nach der Studie deutlich besser informiert und neigen dazu ihr Sparverhalten stärker anzupassen als Personen ohne Zugang. Die außerordentlich hohe Bereitschaft zur Teilnahme und die Antworten in den Online-Befragungen sind zudem Beleg für den großen Bedarf an systemgestützter, individueller Rententransparenz. Soll ein Rentencockpit Verbreitung in Deutschland finden, scheint eine automatisierte, elektronische Bereitstellung von Vertragsdaten von Seiten der Rententräger jedoch unabdingbar, da die eigenständige Suche und teilmanuelle Bereitstellung von Standmitteilungen für die meisten Studienteilnehmer ein großes Hindernis darstellt.
In diesem Beitrag wird ein Vorschlag vorgestellt, wie es trotz langfristiger Niedrigzinsen möglich ist, die vor 18 Jahren eingeführte Riester-Rente so umzugestalten, dass alle Beteiligten davon profitieren. Wird die Mindestauszahlung am Ende der Vertragslaufzeit nur für die Eigenbeiträge, nicht aber für die staatlichen Zulagen garantiert, können deutlich höhere Renditen erzielt werden. Unter dem Strich haben dann nicht nur Privatleute mehr Geld aus ihrer Altersvorsorge, sondern der Staat wird mehr Steuern einnehmen und die Anbieter haben mehr Spielraum für bedarfsgerechte Produktgestaltung.
Self-control failure is among the major pathologies (Baumeister et al. (1994)) affecting individual investment decisions which has hardly been measurable in empirical research. We use cigarette addiction identified from checking account transactions to proxy for low self-control and compare over 5,000 smokers to 14,000 nonsmokers. Smokers self-directing their investment trade more frequently, exhibit more biases and achieve lower portfolio returns. We also find that smokers, some of which might be aware of their limited levels of self-control, exhibit a higher propensity than nonsmokers to delegate decision making to professional advisors and fund managers. We document that such precommitments work successfully.
INDIVIDUALS WITH LOWER SELF-CONTROL OFTEN FAIL IN STICKING TO THEIR PLANS WHEN FACING STRONG TEMPTATIONS. ARE THEY ALSO PRONE TO EXHIBIT INVESTMENT BIASES AND SHOW A MORE IMPULSIVE TRADING BEHAVIOR WHILE FORFEITING POTENTIAL PERFORMANCE IN A FINANCIAL CONTEXT? WE USE CIGARETTE ADDICTION, IDENTIFIED THROUGH CHECKING ACCOUNT TRANSACTIONS, AS A PROXY FOR LOW SELFCONTROL AND COMPARE THE INVESTMENT BEHAVIOR OF SMOKERS TO THAT OF NONSMOKERS TO ADDRESS THIS QUESTION EMPIRICALLY.
Smart(phone) investing? A within investor-time analysis of new technologies and trading behavior
(2021)
Using transaction-level data from two German banks, we study the effects of smartphones on investor behavior. Comparing trades by the same investor in the same month across different platforms, we find that smartphones increase purchasing of riskier and lottery-type assets and chasing past returns. After the adoption of smartphones, investors do not substitute trades across platforms and buy also riskier, lottery-type, and hot investments on other platforms. Using smartphones to trade specific assets or during specific hours contributes to explain our results. Digital nudges and the device screen size do not mechanically drive our results. Smartphone effects are not transitory.
RECENTLY, PASSIVE ETFS AND INDEX FUNDS HAVE BECOME POPULAR AMONG INDIVIDUAL INVESTORS. IN OUR STUDY, WE INVESTIGATE WHETHER INDIVIDUAL INVESTORS BENEFIT FROM USING THEM. WITH DATA FROM ONE OF THE LARGEST BROKERAGES IN GERMANY, WE FIND THAT INDIVIDUAL INVESTORS WORSEN THEIR PORTFOLIO PERFORMANCE AFTER USING THESE PRODUCTS IN COMPARISON TO NON-USERS. SINCE THESE SECURITIES MAKE MARKET TIMING EASIER, FURTHER ANALYSIS REVEALS THAT THE DECREASE IN USERS’ PORTFOLIO PERFORMANCE IS PRIMARILY DUE TO BAD MARKET TIMING.
THIS STUDY INVESTIGATES WHAT HAPPENS WHEN RETAIL CUSTOMERS ARE OFFERED FREE AND UNBIASED ADVICE. USING A LARGE FIELD EXPERIMENT IT SHOWS THAT THOSE WHO ACCEPT THE OFFER (5%) ARE MORE LIKELY TO BE MALE, OLDER, WEALTHIER, MORE EXPERIENCED AND MORE FINANCIALLY SOPHISTICATED. HOWEVER, EVEN THOUGH THE ADVICE WOULD HAVE HELPED, IT ACTUALLY LARGELY FAILED TO HELP BECAUSE THE CUSTOMERS DID NOT LISTEN TO IT. OVERALL, OUR RESULTS SUGGEST THAT THE MERE AVAILABILITY OF UNBIASED FINANCIAL ADVICE IS A NECESSARY BUT NOT SUFFICIENT CONDITION FOR BENEFITING RETAIL CUSTOMERS.
WE DECOMPOSE INDIVIDUAL INVESTORS’ PORTFOLIO RETURNS INTO PASSIVE BENCHMARK RETURNS, ACTIVE SECURITY SELECTION RETURNS, AND ACTIVE MARKET TIMING RETURNS. FOR THE AVERAGE INVESTOR IN OUR SAMPLE, PASSIVE BENCHMARK RETURNS EXPLAIN SOME 40% OF VARIATION IN LONGITUDINAL PORTFOLIO RETURNS, SECURITY SELECTION EXPLAINS AN ADDITIONAL 50%, AND MARKET TIMING PLAYS ONLY A MINOR ROLE. THIS STANDS IN STARK CONTRAST TO EARLIER RESULTS ON INSTITUTIONAL INVESTORS WHERE PASSIVE BENCHMARK RETURNS (REFLECTING DIFFERENT ASSET ALLOCATION STRATEGIES) EXPLAIN OVER 90%. THE PREDOMINANCE OF SECURITY SELECTION COMES AT A COST FOR INDIVIDUAL INVESTORS: INVESTORS FROM THE HIGHEST QUINTILE IN TERMS OF SECURITY SELECTION ACTIVITY UNDERPERFORM THEIR PEERS FROM THE LOWEST QUINTILE BY MORE THAN 10 PERCENTAGE POINTS PER YEAR. TRANSACTION COSTS EXPLAIN ONLY PART OF THIS UNDERPERFORMANCE. THE LESS INVESTORS DIVERSIFY, THE WORSE THEY DO.
Incentivized experiments in which individuals receive monetary rewards according to the outcomes of their decisions are regarded as the gold standard for preference elicitation in experimental economics. These task-related real payments are considered necessary to reveal subjects' "true preferences". Using a systematic, large-sample approach with three subject pools of private investors, professional investors, and students, we test the effect of task-related monetary incentives on risk preferences elicited in four standard experimental tasks. We find no systematic differences in behavior between subjects in the incentivized and non-incentivized regimes. We discuss implications for academic research and for applications in the field.
We merge administrative information from a large German discount brokerage firm with regional data to examine if financial advisors improve portfolio performance. Our data track accounts of 32,751 randomly selected individual customers over 66 months and allow direct comparison of performance across self-managed accounts and accounts run by, or in consultation with, independent financial advisors. In contrast to the picture painted by simple descriptive statistics, econometric analysis that corrects for the endogeneity of the choice of having a financial advisor suggests that advisors are associated with lower total and excess account returns, higher portfolio risk and probabilities of losses, and higher trading frequency and portfolio turnover relative to what account owners of given characteristics tend to achieve on their own. Regression analysis of who uses an IFA suggests that IFAs are matched with richer, older investors rather than with poorer, younger ones.
Peer effects can lead to better financial outcomes or help propagate financial mistakes across social networks. Using unique data on peer relationships and portfolio composition, we show considerable overlap in investment portfolios when an investor recommends their brokerage to a peer. We argue that this is strong evidence of peer effects and show that peer effects lead to better portfolio quality. Peers become more likely to invest in funds when their recommenders also invest, improving portfolio diversification compared to the average investor and various placebo counterfactuals. Our evidence suggests that social networks can provide good advice in settings where individuals are personally connected.
WE STUDY WHETHER PRIVATE EQUITY (PE) FIRMS HAVE A POSITIVE IMPACT ON THE FINANCIAL PERFORMANCE OF THEIR GERMAN PORTFOLIO COMPANIES BEFORE AND AFTER THE IPO. OUR EMPIRICAL ANALYSIS IS BASED ON A UNIQUE AND LARGE DATASET OF ALL IPOS IN GERMANY BETWEEN 2000 AND 2007. WE FIND THAT PE FIRMS SELECT COMPANIES WITH BELOW AVERAGE PERFORMANCE AND THEN IMPROVE PERFORMANCE SUBSTANTIALLY UNTIL THE IPO DATE AND IN MANY CASES ALSO THEREAFTER. THIS IMPLIES THAT PE FIRMS FILL A VOID ALSO IN GERMAN FINANCIAL MARKETS AND THAT THEY WILL ALSO PLAY A FUTURE ROLE IN FINANCING GERMAN ENTERPRISES.
UNDERSTANDING HOW HOUSEHOLDS REACT TO THE ARRIVAL OF PERMANENT AND TRANSITORY INCOME IS OF INTEREST FOR RESEARCHERS AND REGULATORS. PREVIOUS STUDIES HAD TO USE IMPRECISE SURVEY DATA TO MEASURE CONSUMPTION AND THUS CONCLUSIONS OFTEN DIVERGED. WE LEVERAGE GRANULAR PERSONAL FINANCE MANAGEMENT FINTECH DATA TO TEST FRIEDMAN'S PERMANENT INCOME HYPOTHESIS AND TO ASSESS HOUSEHOLD SPENDING ELASTICITY AND MARGINAL PROPENSITY TO CONSUME FOR VARIOUS SPENDING CATEGORIES IN RESPONSE TO DIFFERENT INCOME TYPES.
INDIVIDUAL INVESTORS ARE REPEATEDLY FOUND TO UNDERPERFORM RELATIVE TO A MARKET INDEX. BESIDES EXCESSIVE TRADING, LITTLE IS KNOWN WHEN RETAIL INVESTORS COLLECTIVELY LOSE. THIS ARTICLE SHOWS THAT TRADING IN SHORT-SELLING CONSTRAINED, VOLATILE STOCKS AROUND EARNINGS ANNOUNCEMENTS IS COSTLY TO INDIVIDUAL INVESTORS. THE EFFECT IS PARTICULARLY PRONOUNCED FOR LESS SOPHISTICATED INVESTORS.
ROBO-ADVICE HAS THE POTENTIAL TO DISRUPT THE MARKET FOR FINANCIAL ADVICE. ALGORITHMS ALREADY DELIVER LOW-COST, AUTOMATIC, AND STANDARDIZED INVESTMENT GUIDANCE TO CLIENTS FROM ALL WEALTH LEVELS AND ESPECIALLY TO THOSE PREVIOUSLY EXCLUDED FROM PERSONAL FACE-TO-FACE ADVICE. TODAY’S OFFERINGS CONCENTRATE ON CONVENIENCE AND COMPLEXITY REDUCTION, COUPLED WITH PASSIVE INVESTMENTS. THE NEXT STEP WILL ADVANCE ALGORITHMS TO DELIVER TAILOR-MADE DECISION SUPPORT FOR THE GROWING NUMBER OF SELF-DIRECTED INVESTORS. THIS ARTICLE PRESENTS REAL-LIFE EMPIRICAL RESULTS ON THE INTRODUCTION OF A PORTFOLIO OPTIMIZATION TOOL THAT GUIDES BROKERAGE CLIENTS TOWARDS INDIVIDUAL OPTIMAL PORTFOLIOS.
We show that financial advisors recommend more costly products to female clients, based on minutes from about 27,000 real-world advisory meetings and client portfolio data. Funds recommended to women have higher expense ratios controlling for risk, and women less often receive rebates on upfront fees for any given fund. We develop a model relating these findings to client stereotyping, and empirically verify an additional prediction: Women (but not men) with higher financial aptitude reject recommendations more frequently. Women state a preference for delegating financial decisions, but appear unaware of associated higher costs. Evidence of stereotyping is stronger for male advisors.
Fiscal policies and household consumption during the COVID-19 pandemic: a review of early evidence
(2020)
We review early evidence on how household consumption behavior has evolved over the pandemic and how different groups of households have responded to fiscal stimulus programs. Due to the scarcity of evidence for Europe, our review focuses on evidence from the US. Notwithstanding the institutional and demographic differences, we highlight generalizable findings and challenges to the design of stimulus policies from the pandemic. In conclusion, we identify several open issues for dis cussion.
The European Commission has published a Green Paper outlining possible measures to create a single market for capital in Europe. Our comments on the Commission’s capital markets union project use the functional finance approach as a starting point. Policy decisions, according to the functional finance perspective, should be essentially neutral (agnostic) in terms of institutions (level playing field). Our main angle, from which we assess proposals for the capital markets union agenda, are information asymmetries and the agency problems (screening, monitoring) which arise as a result. Within this perspective, we make a number of more specific proposals.
Previous studies document a relationship between gambling activity at the aggregate level and investments in securities with lottery-like features. We combine data on individual gambling consumption with portfolio holdings and trading records to examine whether gambling and trading act as substitutes or complements. We find that gamblers are more likely than the average investor to hold lottery stocks, but significantly less likely than active traders who do not gamble. Our results suggest that gambling behavior across domains is less relevant compared to other portfolio characteristics that predict investing in high-risk and high-skew securities, and that gambling on and off the stock market act as substitutes to satisfy the same need, e.g., sensation seeking.
WE STUDY REDISTRIBUTIVE EFFECTS OF INFLATION USING A RANDOMIZED INFORMATION EXPERIMENT ON BANK CLIENTS. ON AVERAGE, INDIVIDUALS ARE WELL INFORMED ABOUT CURRENT INFLATION AND ARE CONCERNED ABOUT ITS IMPACT ON WEALTH. YET, MOST INDIVIDUALS ARE NOT AWARE OF HOW INFLATION ERODES NOMINAL POSITIONS. ONCE THEY RECEIVE INFORMATION ON THIS EROSION CHANNEL, THEY UPDATE PERCEPTIONS AND EXPECTATIONS ABOUT OWN NET NOMINAL POSITIONS. LEARNING ABOUT THE INFLATION-INDUCED EROSION OF NOMINAL POSITIONS CAUSALLY AFFECTS CHOICES IN HYPOTHETICAL REAL-ESTATE TRANSACTIONS AND ACTUAL CONSUMPTION. THE FINDINGS SUGGEST THAT HOUSEHOLD WEALTH MEDIATES THE SENSITIVITY OF CONSUMPTION TO INFLATION ONCE HOUSEHOLDS ARE AWARE OF THE BALANCE-SHEET EFFECTS OF INFLATION.
ON JUNE 18TH, WIRECARD’S SHARE PRICE PLUMMETED BY MORE THAN 60% FOLLOWING THE FIRM’S ADMISSION OF BEING SUBJECT TO “ENORMOUS FRAUD” AND BILLIONS OF EUROS MISSING. THIS REPORT DOCUMENTS GERMAN RETAIL INVESTORS’ RESPONSE AND FINDS THAT THE POPULARITY OF WIRECARD AMONG RETAIL INVESTORS LED TO SUBSTANTIAL LOSSES IN THEIR PORTFOLIOS. THESE LOSSES WERE EXACERBATED BY STRONG BUYING SENTIMENT AFTER THE ANNOUNCEMENT. THE FAILING STOCK WAS PURCHASED BY INVESTORS ALREADY ENGAGED IN IT AS WELL AS NON-EXPOSED CUSTOMERS.
Using a field study at a German brokerage, we investigate advised individual investors’ behavior and outcomes after self-selecting into a flat-fee scheme (percentage of portfolio value) for mutual funds. In a difference-in-differences setting, we compare 699 switchers to propensity-score-matched advisory clients who remained in the commission-based scheme. Switchers increase their portfolio values, improve portfolio diversification, and increase their portfolio performance. They also demand more financial advice and follow more advisor recommendations. We argue that switchers attribute a higher quality to the unchanged advisory services.
Consuming dividends
(2020)
This paper studies why investors buy dividend-paying assets and how they time their consumption accordingly. We combine administrative bank data linking customers’ consumption transactions and income to detailed portfolio data and survey responses on financial behavior. We find that private consumption is excessively sensitive to dividend income. Investors across wealth, income, and age distributions increase spending precisely around days of dividend receipt. Importantly, the consumption response is driven by financially prudent investors who select dividend portfolios, anticipate dividend income, and plan consumption accordingly. Our results contribute to the literature on a dividend clientele and provide evidence of ‘planned’ excess sensitivity.
What does your personality reveal about your financial behavior? Evidence from a FinTech experiment
(2022)
We co-operate with a German financial account aggregator (FAA) and conduct a personality survey with 1,700 app users. We combine the survey results with their anonymized transaction data and investigate links between personality traits and spending behavior. Observing many lottery windfalls in our dataset and treating these incidents as real-life experiments, we ask: what do individuals do with unexpected income changes? Our findings suggest that highly extraverted individuals tend to overspend in response to lottery windfalls.
We educate investors with significant dividend holdings about the benefits of dividend reinvestment and the costs of misperceiving dividends as additional, free income. The intervention increases planned dividend reinvestment in survey responses. Using trading records, we observe a corresponding causal increase in dividend reinvestment in the field of roughly 50 cents for every euro received. This holds relative to their prior behavior and a placebo sample. Investors who learned the most from the intervention update their trading by the largest extent. The results suggest the free dividends fallacy is a significant source of dividend demand. Our study demonstrates that simple, targeted, and focused educational interventions can affect investment behavior.
We conduct a field experiment with clients of a German universal bank to explore the impact of peer information on sustainable retail investments. Our results show that infor-mation about peers’ inclination towards sustainable investing raises the amount allocated to stock funds labeled sustainable, when communicated during a buying decision. This effect is primarily driven by participants initially underestimating peers’ propensity to invest sustainably. Further, treated individuals indicate an increased interest in addi-tional information on sustainable investments, primarily on risk and return expectations. However, when analyzing account-level portfolio holding data over time, we detect no spillover effects of peer information on later sustainable investment decisions.
We study the redistributive effects of inflation combining administrative bank data with an information provision experiment during an episode of historic inflation. On average, households are well-informed about prevailing inflation and are concerned about its impact on their wealth; yet, while many households know about inflation eroding nominal assets, most are unaware of nominal-debt erosion. Once they receive information on the debt-erosion channel, households update upwards their beliefs about nominal debt and their own real net wealth. These changes in beliefs causally affect actual consumption and hypothetical debt decisions. Our findings suggest that real wealth mediates the sensitivity of consumption to inflation once households are aware of the wealth effects of inflation.
Inflation and trading
(2024)
We study how investors respond to inflation combining a customized survey experiment with trading data at a time of historically high inflation. Investors' beliefs about the stock return-inflation relation are very heterogeneous in the cross section and on average too optimistic. Moreover, many investors appear unaware of inflation-hedging strategies despite being otherwise well-informed about inflation and asset returns. Consequently, whereas exogenous shifts in inflation expectations do not impact return expectations, information on past returns during periods of high inflation leads to negative updating about the perceived stock-return impact of inflation, which feeds into return expectations and subsequent actual trading behavior.
