Economic theory suggests that a commitment by a firm to increased levels of disclosure should lower the information asymmetry component of the firm’s cost of capital. But whi le the theory is compelling, so far empirical results relating increased levels of disclosure to measurable economic benefits have been mixed. One explanation for the mixed results among studies using data from firms publicly registered in the US is that, under current US reporting standards, the disclosure environment is already rich. In this paper, we study German firms that have switched from the German to an international reporting regime (IAS or US -GAAP), thereby committing themselves to increased le vels of disclosure. We show that proxies for the information asymmetry component of the cost of capital for the switching firms, namely the bid-ask spread and trading volume, behave in the predicted direction compared to firms employing the German reporti ng regime.
Manipulative communications touting stocks are common in capital markets around the world. Although the price distortions created by so-called “pump-and-dump” schemes are well known, little is known about the investors in these frauds. By examining 421 “pump-and-dump” schemes between 2002 and 2015 and a proprietary set of trading records for over 110,000 individual investors from a major German bank, we provide evidence on the participation rate, magnitude of the investments, losses, and the characteristics of the individuals who invest in such schemes. Our evidence suggests that participation is quite common and involves sizable losses, with nearly 6% of active investors participating in at least one “pump-and-dump” and an average loss of nearly 30%. Moreover, we identify several distinct types of investors, some of which should not be viewed as falling prey to these frauds. We also show that portfolio composition and past trading behavior can better explain participation in touted stocks than demographics. Our analysis offers insights into the challenges associated with designing effective investor protection against market manipulation.
Financial ties between drug companies and medical researchers are thought to bias results published in medical journals. To enable readers to account for such bias, most medical journals require authors to disclose potential conflicts of interest. For such policies to be effective, conflict disclosure must modify readers’ beliefs. We therefore examine whether disclosure of financial ties with industry reduces article citations, indicating a discount. A challenge to estimating this effect is selection as drug companies may seek out higher quality authors as consultants or fund their studies, generating a positive correlation between disclosed conflicts and citations. Our analysis confirms this positive association. Including observable controls for article and author quality attenuates but does not eliminate this relation. To tease out whether other researchers discount articles with conflicts, we perform three tests. First, we show that the positive association is weaker for review articles, which are more susceptible to bias. Second, we examine article recommendations to family physicians by medical experts, who choose from articles that are a priori more homogenous in quality. Here, we find a significantly negative association between disclosure and expert recommendations, consistent with discounting. Third, we conduct an analysis within author and article, exploiting journal policy changes that result in conflict disclosure by an author. We examine the effect of this disclosure on citations to a previously published article by the same author. This analysis reveals a negative citation effect. Overall, we find evidence that disclosures negatively affect citations, consistent with the notion that other researchers discount articles with disclosed conflicts.
This paper studies the incentives of German firms to voluntarily disclose cash flow statements over time. While cash flow statement are mandated under many GAAP regimes, its disclosure has not been mandatory in Germany until recently. Nevertheless, an increasing number of firms provides cash flow statements voluntarily. These firms are likely to be influenced by recommendations of the German accounting profession, IAS 7 as well as the respective standards of other countries. The idea of the paper is to study this influence by looking at the adoption pattern over time and the format of the cash flow statement. It documents the development of voluntary cash flow statement disclosures by German firms with respect to ”milestones” in the evolution of German professional recommendations and respective international standards. The cross-sectional determinants of voluntary and international cash flow statements are analyzed using probit regressions and factor analysis. The results are generally consistent with the idea that capital-market forces drive voluntary cash flow statements that are in line with international reporting practice.
This paper investigates whether firms employing IAS or US GAAP exhibit measurable differences in proxies for information asymmetry and market liquidity. Sample firms are drawn from the "New Market" at the Frankfurt Stock Exchange. All firms listed in this market segment are required to provide financial statements in accordance with either IAS or US GAAP as part of the listing agreement. The sample choice provides a market-based comparison of the two standards holding disclosure requirements and standard enforcement constant. I find that differences in the bid-ask spread and trading volume are relatively small and more likely to be driven by firm characteristics than the choice of accounting standards. In contrast, New Market firms have lower spreads and higher turnover when compared with size-matched firms in other market segments following German GAAP. The results suggests that rigid disclosure regulation of the New Market matters in terms of information asymmetry and liquidity, but that the choice between IAS and US GAAP is of second order importance.

The use of evidence and economic analysis in policymaking is on the rise, and accounting standard setting and financial regulation are no exception. This article discusses the promise of evidence-based policymaking in accounting and financial markets as well as the challenges and opportunities for research supporting this endeavor. In principle, using sound theory and robust empirical evidence should lead to better policies and regulations. But despite its obvious appeal and substantial promise, evidence-based policymaking is easier demanded than done. It faces many challenges related to the difficulty of providing relevant causal evidence, lack of data, the reliability of published research, and the transmission of research findings. Overcoming these challenges requires substantial infrastructure investments for generating and disseminating relevant research. To illustrate this point, I draw parallels to the rise of evidence-based medicine. The article provides several concrete suggestions for the research process and the aggregation of research findings if scientific evidence is to inform policymaking. I discuss how policymakers can foster and support policy-relevant research, chiefly by providing and generating data. The article also points to potential pitfalls when research becomes increasingly policy-oriented.
Armstrong et al. (2022) review the empirical methods used in the accounting literature to draw causal inferences. They document a growing number of studies using quasi-experimental methods and provide a critical perspective on this trend as well as the use of these methods in the accounting literature. In this discussion, I complement their review by broadening the perspective. I argue for a design-based approach to accounting research that shifts attention from methods to the entire research design. I also discuss why studies that aim to draw causal inferences are important, how these studies fit into the scientific process, and why assessing the strength of the research design is important when evaluating studies and aggregating research findings.
The paper discusses the policy implications of the Wirecard scandal. The study finds that all lines of defense against corporate fraud, including internal control systems, external audits, the oversight bodies for financial reporting and auditing and the market supervisor, contributed to the scandal and are in need of reform. To ensure market integrity and investor protection in the future, the authors make eight suggestions for the market and institutional oversight architecture in Germany and in Europe.
Eurobonds zur Bewältigung der europäischen Krise? : Wegweisung zu einer modernen Entwicklungsunion
(2011)
Die aktuelle Debatte um den Umgang mit der Verschuldung Griechenlands und anderer EWU Staaten berührt die Grundlagen europäischer Wirtschaftspolitik. Die nächsten Schritte sind wohl abzuwägen, um über eine unmittelbare Kriseneindämmung hinaus eine langfristige Stabilisierung der wirtschaftlichen und politischen Strukturen in der Eurozone zu erreichen.
Eine funktionsfähige Wirtschafts- und Währungsunion hat ihren Preis. Sie ist aber auch von großem Nutzen, gerade für Deutschland und die wettbewerbsstarken Regionen, die insbesondere vom einheitlichen Binnenmarkt und der monetären Stabilität profitieren. Das rechtfertigt zugleich
eine Unterstützung ökonomisch schwächerer Mitglieder der Union durch die stärkeren. Historisch waren Währungsunionen ohne einen derartigen minimalen fiskalischen Ausgleich nicht dauerhaft. Deshalb sind, wenn man die Währungsunion aufrechterhalten will, zwei Extrempositionen - keine Transfers, um keinen Preis ebenso wie deren Gegenteil: jedwedes Defizit wird bedingungslos finanziert - nicht zielführend. Ein kompletter Haftungsausschluss (no bail-out) ist nicht glaubwürdig, solange unabweisbare Schuldenschnitte von insolventen Staaten oder Regionen (wegen Überschuldung) nicht möglich sind, weil sie innerhalb eines stark integrierten Bankenmarktes potentiell unkontrollierbare Rückwirkungen auslösen. Andererseits liefe die unkonditionierte, dauerhafte Finanzierung regionaler Ungleichgewichte auf Transfervolumina hinaus, die eine Überforderung der Transfergeber darstellten. Sie führte vor allem zu einer Perpetuierung der Probleme, weil Anreize zur letztlich unabdingbaren Anpassung fehlten. Damit bleiben zur Schaffung der Voraussetzungen einer funktionsfähigen Währungsunion nur Optionen, die zwischen den Polen liegen.
In this study, we analyze the trading behavior of banks with lending relationships. We combine detailed German data on banks’ proprietary trading and market making with lending information from the credit register and then examine how banks trade stocks of their borrowers around important corporate events. We find that banks trade more frequently and also profitably ahead of events when they are the main lender (or relationship bank) for the borrower. Specifically, we show that relationship banks are more likely to build up positive (negative) trading positions in the two weeks before positive (negative) news events, and also that they unwind these positions shortly after the event. This trading pattern is more pronounced for unscheduled earnings events, M&A transactions, and after borrower obtain new bank loans. Our results suggest that lending relationships endow banks with important information, highlighting the potential for conflicts of interest in banking, which has been a prominent concern in the regulatory debate.
