Exploring Accounting Research Topic Evolution: An Unsupervised Machine Learning Approach

June Cao, Zhanzhong Gu, Iftekhar Hasan
Journal of International Accounting Research, Nr. 3, 2023
Abstract
This study explores the evolution of accounting research by utilizing an unsupervised machine learning approach. We aim to identify the latent topics of accounting from the 1980s up to 2018, the dynamics and emerging topics of accounting research, and the economic reasons behind those changes. First, based on 23,220 articles from 46 accounting journals, we identify 55 topics using the latent Dirichlet allocation model. To illustrate the connection between topics, we use HistCite to generate a citation map along a timeline. The citation clusters demonstrate the “tribalism” phenomenon in accounting research. We then implement the dynamic topic model to reveal the dynamics of topics to show changes in accounting research. The emerging research trends are identified from the topic analytics. We further explore the economic reasons and in-depth insights into the topic evolution, indicating the economic development embeddedness nature of accounting research.

"Let Me Get Back to You" — A Machine Learning Approach to Measuring NonAnswers

Andreas Barth, Sasan Mansouri, Fabian Wöbbeking
Management Science, Nr. 10, 2023
Abstract
Using a supervised machine learning framework on a large training set of questions and answers, we identify 1,364 trigrams that signal nonanswers in earnings call questions and answers (Q&A). We show that this glossary has economic relevance by applying it to contemporaneous stock market reactions after earnings calls. Our findings suggest that obstructing the flow of information leads to significantly lower cumulative abnormal stock returns and higher implied volatility. As both our method and glossary are free of financial context, we believe that the measure is applicable to other fields with a Q&A setup outside the contextual domain of financial earnings conference calls.

Cultural Norms and Corporate Fraud: Evidence from the Volkswagen Scandal

Iftekhar Hasan, Felix Noth, Lena Tonzer
Journal of Corporate Finance, October 2023
Abstract

We examine a corporate governance role of local culture via its impact on consumer behavior following corporate scandals. Our proxy for culture is the presence of local Protestantism. Exploiting the unexpected nature of the Volkswagen (VW) diesel scandal in September 2015, we show that new registrations of VW cars decline significantly in German counties with a Protestant majority following the VW scandal. Further survey evidence shows that, compared to Catholics, Protestants respond significantly more negatively to fraud but not to environmental issues. Our findings suggest that the enforcement culture in Protestantism facilitates penalizing corporate fraud.

Gemeinschaftsdiagnose: Kaufkraft kehrt zurück – Politische Unsicherheit hoch

Dienstleistungsauftrag des Bundesministeriums für Wirtschaft und Klimaschutz, Nr. 2, 2023
Abstract
Deutschland befindet sich seit über einem Jahr im Abschwung. Der sprunghafte Anstieg der Energiepreise im Jahr 2022 hat der Erholung von der Pandemie ein jähes Ende bereitet. Die schon zuvor anziehende Verbraucherpreisinflation ist zwischenzeitlich auf über 8% gestiegen. Dadurch wird den privaten Haushalten Kaufkraft entzogen. Die Leitzinsen sind um über vier Prozentpunkte gestiegen. Das trifft insbesondere die Bauwirtschaft.

Die Stimmung in den Unternehmen hat sich zuletzt erneut verschlechtert, dazu trägt auch politische Unsicherheit bei. Insgesamt deuten die Indikatoren darauf hin, dass die Produktion im dritten Quartal 2023 nochmals spürbar gesunken ist. Allerdings haben mittlerweile die Löhne aufgrund der Teuerung angezogen, die Energiepreise abgenommen und die Exporteure die höheren Kosten teilweise weitergegeben, sodass Kaufkraft zurückkehrt. Daher dürfte der Abschwung zum Jahresende abklingen und der Auslastungsgrad der Wirtschaft im weiteren Verlauf wieder steigen.

Alles in allem wird das Bruttoinlandsprodukt im Jahr 2023 um 0,6% sinken. Damit revidieren die Institute ihre Prognose vom Frühjahr 2023 kräftig um 0,9 Prozentpunkte nach unten. Der wichtigste Grund dafür ist, dass sich die Industrie und der Konsum langsamer erholen als im Frühjahr prognostiziert worden war. Für das Jahr 2024 liegt die Prognose mit 1,3% nur 0,2 Prozentpunkte unter der aus dem Frühjahr. Danach wird sich bemerkbar machen, dass das Potenzialwachstum aufgrund der schrumpfenden Erwerbsbevölkerung mittelfristig deutlich zusammenschmilzt.

Declining Business Dynamism in Europe: The Role of Shocks, Market Power, and Technology

Filippo Biondi, Sergio Inferrera, Matthias Mertens, Javier Miranda
IWH-CompNet Discussion Papers, Nr. 2, 2023
Abstract
We study changes in business dynamism in Europe after 2000 using novel micro-aggregated data that we collected for 19 European countries. In all countries, we document a broad-based decline in job reallocation rates that concerns most economic sectors and size classes. This decline is mainly driven by dynamics within sectors, size, and age classes rather than by compositional changes. Large and mature firms experience the strongest decline in job reallocation rates. Simultaneously, the employment shares of young firms decline. Consistent with US evidence, firms’ employment has become less responsive to productivity shocks. However, the dispersion of firms’ productivity shocks has decreased too. To enhance our understanding of these patterns, we derive and apply a novel firm-level framework that relates changes in firms’ sales, market power, wages, and production technology to firms’ responsiveness and job reallocation.

Common Venture Capital Investors and Startup Growth

Ofer Eldar, Jillian Grennan
Review of Financial Studies, Nr. 2, 2023
Abstract

We exploit the staggered introduction of liability waivers when investors hold stakes in conflicting business opportunities as a shock to venture capital (VC) investment and director networks. After the law changes, we find increases in within-industry VC investment and common directors serving on startup boards. Despite the potential for rent extraction, same-industry startups inside VC portfolios benefit by raising more capital, failing less, and exiting more successfully. VC directors serving on other startup boards are the primary mechanism associated with positive outcomes, consistent with common VC investment facilitating informational exchanges in VC portfolios.

Konjunktur aktuell: Deutschland weiter im Abschwung

Konjunktur aktuell, Nr. 3, 2023
Abstract
Die Weltwirtschaft verliert im Herbst 2023 weiter an Schwung. Die Produktion im Verarbeitenden Gewerbe und der globale Warenhandel stagnieren, gestiegene Leitzinsen verschlechtern das Investitionsklima. Die restriktive Wirtschaftspolitik drückt vor allem die europäische Konjunktur, welche zusätzlich von der Unsicherheit durch den russischen Angriffskrieg belastet wird. In Deutschland belasten die hohe Inflation, gestiegene Zinsen, eine schwache Auslandsnachfrage und Verunsicherung unter privaten Haushalten und Unternehmen die Wirtschaft. Die konjunkturellen Risiken sind für die Bauwirtschaft besonders hoch. Alles in allem dürfte das Bruttoinlandsprodukt 2023 um 0,5% zurückgehen, für das kommende Jahr wird ein Zuwachs von 0,9% prognostiziert.

Safety Net or Helping Hand? The Effect of Job Search Assistance and Compensation on Displaced Workers

Daniel Fackler, Jens Stegmaier, Richard Upward
IWH Discussion Papers, Nr. 18, 2023
Abstract
We provide the first systematic evidence on the effectiveness of a contested policy in Germany to help displaced workers. So-called “transfer companies” (Transfergesellschaften) employ displaced workers for a fixed period, during which time workers are provided with job-search assistance and are paid a wage which is a substantial fraction of their pre-displacement wage. Using rich and accurate data on workers’ employment patterns before and after displacement, we compare the earnings and employment outcomes of displaced workers who entered transfer companies with those that did not. Workers can choose whether or not to accept a position in a transfer company, and therefore we use the availability of a transfer company at the establishment level as an IV in a model of one-sided compliance. Using an event study, we find that workers who enter a transfer company have significantly worse post-displacement outcomes, but we show that this is likely to be the result of negative selection: workers who lack good outside opportunities are more likely to choose to enter the transfer company. In contrast, ITT and IV estimates indicate that the use of a transfer company has a positive and significant effect on employment rates five years after job loss, but no significant effect on earnings. In addition, the transfer company provides significant additional compensation to displaced workers in the first 12 months after job loss.

Herding Behavior and Systemic Risk in Global Stock Markets

Iftekhar Hasan, Radu Tunaru, Davide Vioto
Journal of Empirical Finance, September 2023
Abstract
This paper provides new evidence of herding due to non- and fundamental information in global equity markets. Using quantile regressions applied to daily data for 33 countries, we investigate herding during the Eurozone crisis, China’s market crash in 2015–2016, in the aftermath of the Brexit vote and during the Covid-19 Pandemic. We find significant evidence of herding driven by non-fundamental information in case of negative tail market conditions for most countries. This study also investigates the relationship between herding and systemic risk, suggesting that herding due to fundamentals increases when systemic risk increases more than when driven by non-fundamentals. Granger causality tests and Johansen’s vector error-correction model provide solid empirical evidence of a strong interrelationship between herding and systemic risk, entailing that herding behavior may be an ex-ante aspect of systemic risk, with a more relevant role played by herding based on fundamental information in increasing systemic risk.
