This paper presents a theory that explains why it is beneficial for banks to engage in circular lending activities on the interbank market. Using a simple network structure, it shows that if there is a non-zero bailout probability, banks can significantly increase the expected repayment of uninsured creditors by entering into cyclical liabilities on the interbank market before investing in loan portfolios. Therefore, banks are better able to attract funds from uninsured creditors. Our results show that implicit government guarantees incentivize banks to have large interbank exposures, to be highly interconnected, and to invest in highly correlated, risky portfolios. This can serve as an explanation for the observed high interconnectedness between banks and their investment behavior in the run-up to the subprime mortgage crisis.
The paper analyzes the mutual influence of the capital structure and the investment decision of a bank, as well as the incentive effects of the bank executives compensation schemes on these decisions. In case the government implicitly or explicitly insures deposits and/or the banks debt, banks are incentivized to invest in risky assets and to have a high leverage. Capital regulation could potentially solve this excessive risk taking problem. However, this is only possible if the regulator can observe and properly measure the investment risks of the bank, which was called into question during the 2008-09 financial crisis. Hence, we propose a regulatory approach that is also able to implement the first best risk taking levels by the bank, but does not require the regulator to know the investment risk of the bank. The regulatory approach involves the implementation of capital requirements, which are made contingent on the management compensation.
In the event of a Greek exit from the Eurozone, the stronger members of the monetary union, especially Germany, face at least two risks: First, the debt of the Greek National Bank vis-à-vis the Eurosystem of central banks will most likely be lost. Secondly, the large flow of capital from Greece and other periphery countries to Germany will accelerate inflation.
Debt-induced crises, including the subprime, are usually attributed exclusively to supply-side factors. We examine the role of social influences on debt culture, emanating from perceived average income of peers. Utilizing unique information from a household survey representative of the Dutch population, that circumvents the issue of defining the social circle, we consider collateralized, consumer, and informal loans. We find robust social effects on borrowing, especially among those who consider themselves poorer than their peers; and on indebtedness, suggesting a link to financial distress. We employ a number of approaches to rule out spurious associations and to handle correlated effects.
We build on previous work on operational performance evaluation of private equity portfolio companies as we are able to at least partially decrypt the black box consisting of restructuring tools these investors use and the corresponding impact on their portfolio companies. Beyond answering whether private equity improves operating efficiency we figure out which of the typical restructuring tools drive operating efficiency. Using a set of over 300 international leveraged buyout transactions in the last thirty years we find that while there is vast improvement in operational efficiency these gains vary considerably. Our top performing transactions are subject to strong equity incentives, frequent asset restructuring and tight control by the investor. Furthermore, investors experience has a positive and financial leverage a negative influence on operational performance.
We investigate the decisions of listed firms to go private once again. We start by revealing that while a significant number of firms which go public is VC-backed, an overproportional share of these VC-backed firms go private later on (they stay on the exchange for an average of 8.5 years). We interpret this very robust pattern such that IPOs of VC-backed firms are to a large extent a temporary rather than a permanent feature of the corporate governance of these firms. We investigate various potential hypotheses why VCs actually seem to be able to bring marginal firms to the exchange by relating the going-private decisions to various characteristics of the IPO market as well as to VC characteristics. We find strong support for the certification ability of VCs: more experienced and reputable VCs are more able to bring marginal firms to public exchanges via an IPOs. These marginal firms backed-by more reputable and experienced VCs are more likely to go private later on. Hence, our analysis suggests that IPOs backed by experienced VCs are most likely to be a temporary rather than the final stage in the life of the portfolio firm. We find no support that reputable VCs underprice their IPO-exits more implying that they have no need to leave more money on the table to take the marginal firms public.
Kaum eine andere Industrie wurde in den vergangenen beiden Jahrzehnten so massiv durch den Einzug der Informationstechnologie geprägt wie der Wertpapierhandel. Traditionelle Geschäftsmodelle haben sich grundlegend verändert. Das klassische Börsenparkett ist nahezu vollständig elektronischen Handelsplattformen gewichen.
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.
In this thesis the behavior of banks in financial markets which banks frequently use to obtain short-term as well as long-term financing is studied. In the first chapter we incorporate an interbank market for collateralized lending among banks into a dynamic, stochastic, general equilibrium (DSGE) framework to analyze the impact of variations in the expected value of the collateral on the interbank lending volume. We find that a central bank which decides to lower the haircut on eligible collateral in repurchase agreements is able to stimulate interbank markets. In the second chapter a microeconomic model of bank behavior on the interbank market is set up to analyze the impact of risk-taking behavior of interbank borrowing banks and uncertainty about their balance sheet quality on the lending behavior of interbank lending banks. It is found that the disruptions on the interbank market are the result of optimal behavior on the part of interbank lending banks in response to the uncertainty about the balance sheet quality of an interbank borrowing bank. In the third chapter we use monthly data on German bank bond spreads and regress it on bank-specific risk factors to assess the degree of market discipline in the German bank bond market. The regression results for the whole German bank bond market indicate that the bond spread does not show signs of market discipline. However, a structural break analysis uncovers that since the beginning of the financial crisis the German bank bond market exhibits at least a weak form of market discipline for bonds issued by medium-size and large banks.
Management Summary: Conducted within the project “Economic Implications of New Models for Information Supply for Science and Research in Germany”, the Houghton Report for Germany provides a general cost and benefit analysis for scientific communication in Germany comparing different scenarios according to their specific costs and explicitly including the German National License Program (NLP).
Basing on the scholarly lifecycle process model outlined by Björk (2007), the study compared the following scenarios according to their accounted costs:
- Traditional subscription publishing,
- Open access publishing (Gold Open Access; refers primarily to journal publishing where access is free of charge to readers, while the authors or funding organisations pay for publication)
- Open Access self-archiving (authors deposit their work in online open access institutional or subject-based repositories, making it freely available to anyone with Internet access; further divided into (i) CGreen Open Access’ self-archiving operating in parallel with subscription publishing; and (ii) the ‘overlay services’ model in which self-archiving provides the foundation for overlay services (e.g. peer review, branding and quality control services))
- the NLP.
Within all scenarios, five core activity elements (Fund research and research communication; perform research and communicate the results; publish scientific and scholarly works; facilitate dissemination, retrieval and preservation; study publications and apply the knowledge) were modeled and priced with all their including activities.
Modelling the impacts of an increase in accessibility and efficiency resulting from more open access on returns to R&D over a 20 year period and then comparing costs and benefits, we find that the benefits of open access publishing models are likely to substantially outweigh the costs and, while smaller, the benefits of the German NLP also exceed the costs.
This analysis of the potential benefits of more open access to research findings suggests that different publishing models can make a material difference to the benefits realised, as well as the costs faced. It seems likely that more Open Access would have substantial net benefits in the longer term and, while net benefits may be lower during a transitional period, they are likely to be positive for both ‘author-pays’ Open Access publishing and the ‘over-lay journals’ alternatives (‘Gold Open Access’), and for parallel subscription publishing and self-archiving (‘Green Open Access’). The NLP returns substantial benefits and savings at a modest cost, returning one of the highest benefit/cost ratios available from unilateral national policies during a transitional period (second to that of ‘Green Open Access’ self-archiving). Whether ‘Green Open Access’ self-archiving in parallel with subscriptions is a sustainable model over the longer term is debateable, and what impact the NLP may have on the take up of Open Access alternatives is also an important consideration. So too is the potential for developments in Open Access or other scholarly publishing business models to significantly change the relative cost-benefit of the NLP over time.
The results are comparable to those of previous studies from the UK and Netherlands. Green Open Access in parallel with the traditional model yields the best benefits/cost ratio. Beside its benefits/cost ratio, the meaningfulness of the NLP is given by its enforceability. The true costs of toll access publishing (beside the buyback” of information) is the prohibition of access to research and knowledge for society.
