We examine the impact of increasing competition among the fastest traders by analyzing a new low-latency microwave network connecting exchanges trading the same stocks. Using a difference-in-differences approach comparing German stocks with similar French stocks, we find improved market integration, faster incorporation of stock-specific information, and an increased contribution to price discovery by the smaller exchange. Liquidity worsens for large caps due to increased sniping but improves for mid caps due to fast liquidity provision. Trading volume on the smaller exchange declines across all stocks. We thus uncover nuanced effects of fast trader participation that depend on their prior involvement.
This paper investigates the implications of monetary policy rules during the surge and subsequent decline of inflation in the euro area and compares them to the interest rate decisions of the European Central Bank (ECB). It focuses on versions of the Taylor (1993) and Orphanides and Wieland (OW) (2013) rules. Rules that respond to recent outcomes of HICP Core or domestic inflation data called for raising interest rates in 2021 and well ahead of the rate increases implemented by the ECB. Thus, such simple outcome-based policy rules deserve more attention in the ECB’s monetary policy strategy. Interestingly, the rules support the recent shift of the ECB to policy easing. Yet, they add a note of caution by suggesting that policy rates should not decline as fast as apparently anticipated by traded derivative-based interest rate forecasts.
We show that exposure to anti-capitalist ideology can exert a lasting influence on attitudes towards capital markets and stock-market participation. Utilizing novel survey, bank, and broker data, we document that, decades after Germany's reunification, East Germans invest significantly less in stocks and hold more negative views on capital markets. Effects vary by personal experience under communism. Results are strongest for individuals remembering life in the German Democratic Republic positively, e. g., because of local Olympic champions or living in a "showcase city". Results reverse for those with negative experiences like religious oppression, environmental pollution, or lack of Western TV entertainment.
We examine the effect of personal, two-way communication on the payment behavior of delinquent borrowers. Borrowers who speak with a randomly assigned bank agent are significantly more likely to successfully resolve the delinquency relative to borrowers who do not speak with a bank agent. Call characteristics related to the human touch of the call, such as the likeability of the agent’s voice, significantly affect payment behavior. Borrowers who speak with a bank agent are also significantly less likely to become delinquent again. Our findings highlight the value of a human element in interactions between financial institutions and their customers.
Die Zustandsbeschreibung der aktuellen gesellschaftlichen und wirtschaftlichen Lage als geprägt durch multiple Schocks und Krisen erscheint heutzutage redundant, nahezu banal. Umso wichtiger ist es aber für politische Entscheider einen Umgang mit der sich daraus ergebenden Unsicherheit zu finden, der weder der Komplexität der Probleme mit immer komplexeren Modellen beikommen möchte noch sich durch die Größe der Krise zur übergroßen vermeintlichen politischen Lösung verleiten lässt. Stattdessen täte die Politik gut daran, die beschränkten Möglichkeiten und die ungewissen Folgen ihrer Handlungen klar zu kommunizieren, qualitative wie quantitative Bewertungen in Entscheidungen einfließen zu lassen und in diesem Sinne wirtschaftspolitische Interventionen zurückhaltend vorzunehmen.
Banking Union is crucial for European integration, ensuring financial stability in the single market for financial services. The Court of Justice of the European Union (CJEU) plays an essential role in interpreting and enforcing the legal framework of the Banking Union, especially regarding the Single Supervisory Mechanism (SSM) and the Single Resolution Mechanism (SRM). This in-depth analysis scrutinises the pertinent CJEU case law and highlights its implications for the Banking Union and the EU legal order.

We provide empirical evidence that the pricing of green bonds tends to be highly sophisticated and based on a two-tiered approach. When buying a green bond, investors do not look only at the green label of the bond but also consider additional characteristics that involve the soundness of the underlying project and the environmental score of the issuer. By comparing the yields at issuance of green bonds to those of a matched control sample of conventional bonds, we identify a premium of 16 basis points for the green label alone. However, when the environmental score of the issuer is in the top tercile of the cross-sectional distribution, the greenium increases up to doubling. Green certification and periods of heightened climate uncertainty also significantly influence the size of the greenium. Additionally, we find that this pricing mechanism fully emerged only after the Paris Agreement came into force in late 2016.
We provide evidence on narratives about the macroeconomy - the stories people tell to explain macroeconomic phenomena - in the context of a historic surge in inflation. In surveys with more than 10,000 US households and 100 academic experts, we measure economic narratives in open-ended survey responses and represent them as Directed Acyclic Graphs. Households' narratives are strongly heterogeneous, coarser than experts' narratives, focus more on the supply side than on the demand side, and often feature politically loaded explanations. Households' narratives matter for their inflation expectation formation, which we demonstrate with descriptive survey data and a series of experiments. Informed by these findings, we incorporate narratives into an otherwise conventional New Keynesian model and demonstrate their importance for aggregate outcomes.
We examine the evolution of spatial house price dispersion during Germany's recent housing boom. Using a dataset of sales listings, we find that house price dispersion has significantly increased, which is driven entirely by rising price variation across postal codes. We show that both price divergence across labor market regions and widening spatial price variation within these regions are important factors for this trend. We propose and estimate a directed search model of the housing market to understand the driving forces of rising spatial price dispersion, highlighting the role of housing supply, housing demand and frictions in the matching process between buyers and sellers. While both shifts in housing supply and housing demand matter for overall price increases and for regional divergence, we find that variation in housing demand is the primary factor contributing to the widening spatial dispersion within labor market regions.
Helmut Schlesinger: Wegbereiter und Garant der deutschen Geld- und Stabilitätspolitik wird 100
(2024)
Am 4. September 2024 vollendet Professor Dr. Helmut Schlesinger sein 100. Lebensjahr. Von 1991 bis 1993 bekleidete er das Amt des Präsidenten der Deutschen Bundesbank. Zuvor war er in verschiedenen Positionen für die Bank tätig, unter anderem als langjähriger Vizepräsident (von 1980 bis 1991) sowie als Leiter der Hauptabteilung Volkswirtschaft und Statistik. Das Jubiläum bietet Anlass, sein Lebenswerk zu beschreiben und zu würdigen. Für ehemalige Mitarbeiter war Helmut Schlesinger ein großes Vorbild und eine Quelle des Ansporns in vielerlei Hinsicht. Insbesondere vier Bereiche seiner Tätigkeiten haben die Arbeit seiner Mitarbeiter maßgeblich geprägt: Erstens seine Fähigkeit, ökonomisches Denken als eine Synthese aus Analyse und Statistik zu begreifen, zu vermitteln und zu organisieren, zweitens sein Verdienst, eine Stabilitätskultur in leitenden Positionen mitgeschaffen und bewahrt zu haben, drittens sein ordnungspolitisches Credo zur Preisstabilität und zur Unabhängigkeit der Zentralbank sowie viertens seine klaren Vorstellungen zu den Bedingungen einer erfolgreichen Europäischen Wirtschafts- und Währungsunion.
Im Folgenden soll ein Überblick über diese vier Schwerpunkte seiner Schaffensbilanz gegeben werden. In diesem Kontext ist insbesondere Schlesingers entscheidende Rolle bei der Schaffung der deutsch-deutschen Währungsunion 1990 sowie beim langjährigen Entstehungsprozess des Eurosystems und der Europäischen Zentralbank hervorzuheben. In der deutschen Bevölkerung, aber auch international hoch geachtet, wurde Helmut Schlesinger oft als die "Seele der Bundesbank" bezeichnet.Die Anforderungen, die er an jeden Einzelnen stellte, waren hoch. Er wurde von den Mitarbeitern sehr geschätzt, nicht zuletzt aufgrund seines großen Arbeitsethos und seiner unermüdlichen Schaffenskraft, die von Beständigkeit, Gradlinigkeit und Prinzipientreue geprägt waren.
I provide a solution method in the frequency domain for multivariate linear rational expectations models. The method works with the generalized Schur decomposition, providing a numerical implementation of the underlying analytic function solution methods suitable for standard DSGE estimation and analysis procedures. This approach generalizes the time-domain restriction of autoregressive-moving average exogenous driving forces to arbitrary covariance stationary processes. Applied to the standard New Keynesian model, I find that a Bayesian analysis favors a single parameter log harmonic function of the lag operator over the usual AR(1) assumption as it generates humped shaped autocorrelation patterns more consistent with the data.
The lack of a European Deposit Insurance Scheme (EDIS) – often referred to as the ‘third pillar’ of Banking Union – has been criticized since the inception of the EU Banking Union. The Crisis Management and Deposit Insurance (CMDI) framework needs to rely heavily on banks’ internal loss absorbing capacity and provides little flexibility in terms of industry resolution funding. This design has, among others, led to the rare application of the CMDI, particularly in the case of small and medium sized retail banks. This reluctance of resolution authorities weakens any positive impact the CMDI may have on market discipline and ultimately financial stability. After several national governments pushed back against the establishment of an EDIS, the Commission recently took a different approach and tried to reform the CMDI comprehensively, without seeking to erect a ‘third pillar’. The overarching rationale of the CMDI Proposal is to make resolution funding more flexible. To this end, the proposal seeks to facilitate contributions from (national) deposit guarantee schemes (DGS). At the same time, the CMDI Proposal tries to broaden the scope of resolution to include smaller and medium sized banks. This paper provides an assessment of the CMDI Proposal. It argues that the CMDI Proposal is a step in the right direction but cannot overcome fundamental deficiencies in the design of the Banking Union.

Cross-predictability denotes the fact that some assets can predict other assets' returns. I propose a novel performance-based measure that disentangles the economic value of cross-predictability into two components: the predictive power of one asset's signal for other assets' returns (cross-predictive signals) and the amount of an asset's return explained by other assets' signals (cross-predicted returns). Empirically, the latter component dominates the former in the overall cross-prediction effects. In the crosssection, cross-predictability gravitates towards small firms that are strongly mispriced and difficult to arbitrage, while it becomes more difficult to cross-predict returns when market capitalization and book-to-market ratio rise.
This paper examines the dynamic relationship between firm leverage and risktaking. We embed the traditional agency problem of asset substitution within a multi-period model, revealing a U-shaped relationship between leverage and risktaking, evident in data from both the U.S. and Europe. Firms with medium leverage avoid risk to preserve the option of issuing safe debt in the future. This option is valuable because safe debt does not incur the expected cost of bankruptcy, anticipated by debt-holders due to future risk-taking incentives. Our model offers new insights on the interaction between companies' debt financing and their risk profiles.
Libra — a global virtual currency project initiated by Facebook — has been the subject of many controversial discussions since its announcement in June 2019. This paper provides a differentiated view on Libra, recognising that different development scenarios of Libra are conceivable. Libra could serve purely as an alternative payment system in combination with a dedicated payment token, the Libra coin. Alternatively, the Libra project could develop into a broader financial infrastructure for advanced financial services such as savings and loan products operating on the Libra Blockchain. Based on a comparison of the Libra architecture with other cryptocurrencies, the opportunities and challenges for the development of the respective Libra ecosystems are investigated from a commercial, regulatory and monetary policy perspective.
The importance of agile methods has increased in recent years, not only to manage IT projects but also to establish flexible and adaptive organisational structures, which are essential to deal with disruptive changes and build successful digital business strategies. This paper takes an industry-specific perspective by analysing the dissemination, objectives and relative popularity of agile frameworks in the German banking sector. The data provides insights into expectations and experiences associated with agile methods and indicates possible implementation hurdles and success factors. Our research provides the first comprehensive analysis of agile methods in the German banking sector. The comparison with a selected number of fintechs has revealed some differences between banks and fintechs. We found that almost all banks and fintechs apply agile methods in IT projects. However, fintechs have relatively more experience with agile methods than banks and use them more intensively. Scrum is the most relevant framework used in practice. Scaled agile frameworks are so far negligible in the German banking sector. Acceleration of projects is apparently the most important objective of deploying agile methods. In addition, agile methods can contribute to cost savings and lead to improved quality and innovation performance, though for banks it is evidently more challenging to reach their respective targets than for fintechs. Overall our findings suggest that German banks are still in a maturing process of becoming more agile and that there is room for an accelerated adoption of agile methods in general and scaled agile frameworks in particular.
The financial sector plays an important role in financing the green transformation. Various regulatory initiatives in the EU aim to improve transparency in relation to the sustainability of financial products and the sustainability of economic activities of non-financial and financial undertakings. For credit institutions, the Green Asset Ratio (GAR) has been established by the European regulatory authorities as a key performance indicator (KPI) for measuring the proportion of Taxonomy-aligned on-balance-sheet exposure in relation to the total assets. The breakdown of the total GAR by type of counterparty, environmental objective and type of asset provides in-depth information about the sustainability profile of a credit institution. This information, which has not been available to date, may also initiate discussions between management and shareholders or other stakeholders regarding the future sustainability strategy of credit institutions. This paper provides an overview of the regulatory background and the method of calculating the GAR along different dimensions. Finally, the potential benefits and limitations of the GAR are discussed.
Advances in distributed ledger technology are leading to a growing decentralisation of financial services (“decentralised finance”) that can be offered largely without intermediation by financial institutions. An important driver for this development is the ongoing tokenisation of assets, payments and rights, which enables the digital encryption of “crypto assets” on distributed ledgers. This article elaborates the foundations and fields of application of decentralised financial services with crypto assets that could challenge the established business models of financial institutions. This trend not only affects payment systems based on controversial crypto currencies such as Bitcoin, but also exchange platforms, capital markets solutions and corporate financing. A rapidly growing ecosystem of start-ups, tech companies and financial institutions is emerging, yet this ecosystem lacks a consistent regulatory framework. The European initiative MiCA (Markets in Crypto Assets) points in the right direction but needs to be adopted soon to ensure the future competitiveness of the European financial sector.
The financial sector plays an important role in supporting the green transformation of the European economy. A critical assessment of the current regulatory framework for sustainable finance in Europe leads to ambiguous results. Although the level of transparency on environmental, social and governance aspects of financial products has improved significantly, it is questionable whether the complex, mainly disclosure-oriented architecture is sufficient to mobilise more private capital into sustainable investments. It should be discussed whether a minimum taxonomy ratio or Green Asset Ratio has to be fulfilled to market a financial product as “green”. Furthermore, because of the high complexity of the regulation, it could be helpful for private investors to establish a simplified green rating, based on the taxonomy ratio, to facilitate the selection of green financial products.
