Crypto Expert Survey, April 2025.

Homepage: https://www.iu.de/forschung/projekte/krypto-expertenumfrage/

Keywords: Crypto experts, survey, expectation formation, crypto business climate index, crypto optimism index, crypto market expectation index.

Abstract: The Crypto Expert Survey is an innovative research project designed to establish a robust empirical foundation for academic research on expectation formation in the crypto sector. It was initiated to address the gap in data collection within this industry by introducing a regular survey of crypto experts from the DACH region. The survey builds on proven methods from well-known economic surveys such as the ZEW Financial Market Survey, CFO Survey (Duke University), or the Survey of Business Uncertainty (Atlanta Fed), adapting them to the specific features of the crypto industry. The resulting Crypto Business Climate Index, the Crypto Optimism Index, and Crypto Market Expectation Indices are publicly available, supporting decision-makers in business and politics.

Quantum Computing in Finance

Work in Progress

Quantum Computing and Financial Services Transformation, with Siddhartha Santra (Indian Institute of Technology, Bombay),  April 2025.

Keywords: Quantum advantage, financial computing problems, financial services disruption, quantum business models.

Abstract: Emerging technologies such as quantum computing are difficult to value for early adopters, so we propose a structured approach that first develops a taxonomy of financial-services computing problems and then estimates quantum computing’s improvement potential across financial services areas. By asking whether a quantum solution is necessary, what its reward/cost profile is, and how deeply each area might be disrupted, we translate time-to-solution and solution-quality gains into dollar-denominated return-on-investment metrics for the next 5–10 years. This framework not only assesses the potential scale of disruption but also identifies innovation opportunities and new business models enabled by quantum computing.

Capital Market Access and Cash Flow Allocation During the Financial Crisis, with Vidhan Goyal (HKUST Business School), February 2017. ssrn.com/abstract=2726048.

Semi-finalist FMA (2016) Best Paper Award (Financial Markets and Institutions).

Keywords: Stock market access, private firms, financial constraints, short-termist pressures, cash flow allocation, financial crisis, bank-based vs. market-based financial markets.

Abstract: To understand how a stock market listing influences corporate policies if external financing is restricted, we examine how European public and counterfactual private firms jointly adjust their investment, financing, payout policies during the global financial crisis – when bank lending tightened. Our findings suggest that a stock market listing provides better access to external debt financing during the crisis as public firms, on average, net issue more long-term debt. Excess debt financing is, however, not allocated to investments but mostly to payouts to shareholders. Thus, a stock market listing relaxes financial constraints but induces managers to cater to shareholders during the crisis. Independent of a country’s financial market structure (bank-based vs. market based) in our European firm sample, a stock market listing always provides a firm with more long-term debt during the crisis. In bank-based economies, this excess debt is mostly allocated to maintain investments while in market-based economies, inducing higher short-termist pressures, a stock-listing leads to lower investments and excess debt is used to maintain payouts.

Managerial Optimism and the Perception of Financial Constraints, with Tobias Heizer (LMU Munich), September 2015. Download: Available upon request.

Keywords: Managerial optimism, perceived financing constraints, distinguishing behavioral and rational predictions, matched survey and financial statement data.

Abstract: We find that optimistic managers are more likely to perceive financing constraints, which is a fundamental but previously untested prediction of behavioral corporate finance theory. However, this effect is statistically significant but relatively small compared to other previously identified determinants of perceived financing constraints. Moreover, the vast majority of optimistic managers actually do not perceive any financing constraints. Our findings have implications for both behavioral corporate finance and financial constraints research. We argue that previous findings relating optimism and corporate policies are probably driven by perceived financing constraints and not optimism. Apart from their potential usefulness, commonly applied financial constraint indices are likely to be biased by not accounting for managerial optimism. Our analysis is based on large survey panel data for high-level managers of 2,897 German firms for the period 1995 to 2010, which is matched with financial and non-financial firm-level information. The data enable us to implement a survey based measure of managerial optimism and to directly access the managers’ perception of financing constraints from survey answers.

An Autopsy of a Total Stock Market Failure, with Ioannis Floros (Wisconsin-Milwaukee) and Shane Johnson (Texas A&M), March 2018. Download: Available upon request.

Abstract: We study a unique case in which a stock market experienced an Akerlof-type failure. We find that a relatively small fraction of ‘bad’ firms combined with high levels of asymmetric information led to a series of Akerlof-type spillovers onto good firms evident in increased trading costs and reduced liquidity and volume. As good firms suffered adverse pricing effects, they exited the market, leading to increases in the fraction of bad firms and further deterioration in the market. Regulators intervened attempting to rescue the market, but the problems accelerated; regulators ultimately shut down the market. Our work sheds light on how stock markets with low transparency and low listing requirements can fail with even just a small fraction of bad firms.
