Finance Research Graz (FiRe)
FiRe Graz is a loosely organized research platform, affiliated with the University of Graz. Founded and operated by the Institute of Banking and Finance and the Institute of Finance, the platform is open to all finance researchers with a connection to the University of Graz and is intended to reach out across organisational boundaries. Its main areas of interest are empirical and experimental research in finance. (more...)

New paper on biases in the peer review publication process05.10.2022
In a new study in the Proceedings of the National Academy of Sciences, FiRe member Stefan Palan and co-authors document bias in the peer review process that precedes the publication of research articles in scientific journals. Even if they are of equal quality, articles authored by prominent researchers get better ratings than articles authored by less well-known researchers.
Implementing an idea by Jürgen Huber (University of Innsbruck), leader of the research team, the authors conducted a simple experiment: Vernon Smith (Professor at Chapman University and Nobel Memorial Prize Laureate in Economics 2002) and Sabiou Inoua (junior post-doc researcher at Chapman University), who were both members of the research team, jointly authored a research article and submitted it to the Journal of Behavioral and Experimental Finance for review. As the editor of this Journal, Stefan Palan sent invitations to review the article to a total of 3300 experts in the field. A total of 534 accepted the invitation to review and submitted a review report. While all reviewers received the same article for their evaluation, they received different information about who had authored the article. One group was informed that Nobel prize laureate Vernon Smith was one of the authors. Another group was informed that junior researcher Sabiou Inoua was one of the authors. A third group did not receive any information about the authors.
Reviewers with different types of information about the article’s authors evaluated the quality of the research article markedly differently. Of the reviewers who had received no information about the article’s authors ("AA" in the figure below), 48.2% recommended against publishing the article. This proportion was even higher among the reviewers who had been informed that one of the authors was the relatively unknown junior researcher ("AL"); here 65.3% recommended against publication. Yet of the reviewers who had been informed that one of the authors was Nobel prize laureate Vernon Smith ("AH"), only 22.5% recommended against publication.
Rudolf Kerschbamer (University of Innsbruck), another member of the research team, traces the source of the different evaluations to the “halo-effect”. This term from social psychology describes the phenomenon that we tend to evaluate the actions and work of someone more favorably when we are favorably disposed towards this person. Christian König genannt Kersting (University of Innsbruck), also a member of the research team, considers the results to constitute an important trigger to start rethinking the scientific review process: “As researchers, we are constantly working on improving our methods and processes. Our results have met great interest from the academic community and many editors of scientific journals are already testing new methods for evaluating and ensuring the quality of research findings.”

New paper on the determinants of cryptocurrency exchange liquidity26.09.2022
Liquidity on cryptocurrency exchanges is an important factor influencing the attractiveness of investing into this new asset class. Since there are important differences between cryptocurrencies and traditional financial instruments, it is plausible that these differences affect the determinants of cryptocurrency liquidity.
In a recent paper platform members Alexander Brauneis, Roland Mestel and Erik Theissen together with their co-author Ryan Riordan (Queen’s University and LMU Munich) study bitcoin to US dollar (BTCUSD) liquidity and liquidity determinants using order book data from three large cryptocurrency exchanges. They find that these BTCUSD markets are more liquid than US equity markets with bid–ask spreads often below 1 basis point. The analysis of the determinants of liquidity reveals that bitcoin liquidity is decoupled from the liquidity of other asset classes such as equities and foreign exchange. In fact, bitcoin liquidity largely depends on factors specific to cryptocurrencies and the blockchain. Specifically, bitcoin market liquidity is driven by the recent past of risk and returns for cryptocurrencies, and the costs with which the blockchain is clearing on-chain transactions. These results are generally consistent with what one would expect based on classic economics models. Market microstructure theory has identified adverse selection costs and, to a lesser extent, inventory holding costs as the main drivers of bid–ask spreads. Thus, to the extent that the time series variation in the degree of informational asymmetry and the inventory holding cost is driven by cryptocurrency-specific variables, we would expect that bitcoin liquidity depends on those variables rather than on general financial market variables.
The paper was presented at the FiRe Research Day in Graz in June 2019 and has recently been accepted for publication in the Journal of Empirical Finance.

Berivan Gürel joins research platform08.08.2022
Berivan Gürel recently joined the research platform as a PhD student under the supervision of Prof. Stefan Palan. Berivan completed her Master's in Accounting & Finance at the University of Edinburgh. Besides her PhD studies, Berivan works in asset management in an insurance company.
In her PhD thesis, she plans to study the financial risk tolerance and risk perception of genders and sexes when making investment decisions.
Field trip to Frankfurt 28.07.2022
Following a successful academic year, about 25 students and members of the Institute of Banking and Finance at the University of Graz used the first days of summer break for a field trip to Frankfurt, Germany. As Germany's most important financial center, the city hosts various commercial banks, the European Central Bank, the Deutsche Bundesbank, and Europe’s third largest stock exchange. This concentration of interesting institutions in one place ensured a program packed with insightful visits and engaging discussions that were focused, among other topics, on macroprudential supervision, the newest developments in (digital) finance, and the link between science and practice.
- European Central Bank: Mandate and functions of the European Central Bank.
- Deutsche Bundesbank: Financial stability, supervision.
- DZ Bank: Security issuances, macroeconomic developments.
- Deutsche Boerse: Regulatory environment, digitalization, ESG.
We want to thank all of our hosts in Frankfurt for the time and effort they invested into making our visit a memorable event! Furthermore, we also want to thank Raiffeisen-Landesbank Steiermark for funding our bachelor and master students’ travel expenses in a continuation of the long-standing good partnership with the Institute of Banking and Finance at the University of Graz.
