What Drives Risk Perception? A Global Survey with Financial Professionals and Laypeople
Risk is an integral part of many economic decisions and is vitally important in finance. Despite extensive research on decision making under risk, little is known about how risks are actually perceived by financial professionals, the key players in global financial markets. In a large-scale survey experiment with 2,213 finance professionals and 4,559 laypeople in nine countries representing ~50% of the world’s population and more than 60% of the world’s gross domestic product, we expose participants to return distributions with equal expected return, and we systematically vary the distributions’ next three higher moments. Of these, skewness is the only moment that systematically affects financial professionals’ perception of financial risk. Strikingly, variance does not influence risk perception, even though return volatility is the most common risk measure in finance in both academia and the industry. When testing other, compound risk measures, the probability to experience losses is the strongest predictor of what is perceived as being risky. Analyzing professionals’ propensity to invest, skewness and loss probability also have strong predictive power, while volatility and kurtosis have some additional effect. Our results are very similar for laypeople, and they are robust across and within countries with different cultural backgrounds, as well as for different job fields of professionals.

Future perspectives in risk models and finance
This book provides a perspective on a number of approaches to financial modelling and risk management. It examines both theoretical and practical issues. Theoretically, financial risks models are models of a real and a financial \"uncertainty\", based on both common and private information and economic theories defining the rules that financial markets comply to. Financial models are thus challenged by their definitions and by a changing financial system fueled by globalization, technology growth, complexity, regulation and the many factors that contribute to rendering financial processes to be continuously questioned and re-assessed. The underlying mathematical foundations of financial risks models provide future guidelines for risk modeling. The bookâءءs chapters provide selective insights and developments that can contribute to better understand the complexity of financial modelling and its ability to bridge financial theories and their practice.

Relation between Audit Effort and Financial Report Misstatements: Evidence from Quarterly and Annual Restatements
We identify two research design issues that explain the inconsistency between the theoretically predicted negative relation between audit effort and misstatements (measured using restatements) and empirical findings. First, auditor risk adjustment behavior induces an upward bias in the association between audit effort and restatements. Second, the theoretical prediction applies only to audited financial reports (i.e., annual reports) and not to unaudited reports (i.e., interim quarterly reports). Comingling restatements of audited with unaudited reports introduces an additional upward bias in the association between audit effort and restatements. After correcting for these two sources of bias, we find a robust negative association between audit effort and annual report restatements.

ESG Disclosure and Idiosyncratic Risk in Initial Public Offerings
Although legitimacy theory provides strong arguments that environmental, social and governance (ESG) disclosure and performance can help mitigate firm-specific (idiosyncratic) risks, this relationship has been repeatedly challenged by conceptual arguments, such as ‘transparency fallacy’ or ‘impression management’, and mixed empirical evidence. Therefore, we investigate this relationship in the revelatory case of initial public offerings (IPOs), which represent the first sale of common stock to the wider public. IPOs are characterised by strong information asymmetry between firm insiders and society, while at the same time suffering from uncertainty in firm legitimacy, culminating in amplified financial risks for both issuers and investors in aftermarket trading. Using data from the United States, we demonstrate that (1) voluntary ESG disclosure reduces idiosyncratic volatility and downside tail risk and (2) higher ESG ratings have lower associated firm-specific volatility and downside tail risk during the first year of trading in the aftermarket. We provide theoretical arguments for the relationships observed, suggesting that companies striving for ESG performance and communicating their efforts signal their compliance with sustainability-related norms, thus acquiring and upholding a societal license to operate. ESG performance and disclosure help companies build their reputation capital with investors after going public. We also report that ESG disclosure is a more consistent proxy for ex-ante uncertainty as an indicator of aftermarket risk, thereby replacing some of the more conventional measures, such as firm age, offered in the existing literature.

Stronger Risk Controls, Lower Risk: Evidence from U.S. Bank Holding Companies
We construct a risk management index (RMI) to measure the strength and independence of the risk management function at bank holding companies (BHCs). The U.S. BHCs with higher RMI before the onset of the financial crisis have lower tail risk, lower nonperforming loans, and better operating and stock return performance during the financial crisis years. Over the period 1995 to 2010, BHCs with a higher lagged RMI have lower tail risk and higher return on assets, all else equal. Overall, these results suggest that a strong and independent risk management function can curtail tail risk exposures at banks.

The bankers' new clothes
What is wrong with today's banking system? The past few years have shown that risks in banking can impose significant costs on the economy. Many claim, however, that a safer banking system would require sacrificing lending and economic growth.The Bankers' New Clothesexamines this claim and the narratives used by bankers, politicians, and regulators to rationalize the lack of reform, exposing them as invalid.
Admati and Hellwig argue we can have a safer and healthier banking system without sacrificing any of the benefits of the system, and at essentially no cost to society. They show that banks are as fragile as they are not because they must be, but because they want to be--and they get away with it. Whereas this situation benefits bankers, it distorts the economy and exposes the public to unnecessary risks. Weak regulation and ineffective enforcement allowed the buildup of risks that ushered in the financial crisis of 2007-2009. Much can be done to create a better system and prevent crises. Yet the lessons from the crisis have not been learned.
Admati and Hellwig seek to engage the broader public in the debate by cutting through the jargon of banking, clearing the fog of confusion, and presenting the issues in simple and accessible terms.The Bankers' New Clothescalls for ambitious reform and outlines specific and highly beneficial steps that can be taken immediately.
