Accounting Information, Disclosure, and the Cost of Capital

Abstract: In this paper we examine whether and how accounting information about a firm manifests in its cost of capital, despite the forces of diversification. We build a model that is consistent with the Capital Asset Pricing Model and explicitly allows for multiple securities whose cash flows are correlated. We demonstrate that the quality of accounting information can influence the cost of capital, both directly and indirectly. The direct effect occurs because higher quality disclosures affect the firm's assessed covariances with other firms' cash flows, which is nondiversifiable. The indirect effect occurs because higher quality disclosures affect a firm's real decisions, which likely changes the firm's ratio of the expected future cash flows to the covariance of these cash flows with the sum of all the cash flows in the market. We show that this effect can go in either direction, but also derive conditions under which an increase in information quality leads to an unambiguous decline in the cost of capital.

Is Information Risk a Determinant of Asset Returns

Abstract: We investigate the role of information-based trading in affecting asset returns. We show in a rational expectation example how private information affects equilibrium asset returns. Using a market microstructure model, we derive a measure of the probability of information-based trading, and we estimate this measure using data for individual NYSE-listed stocks for 1983 to 1998. We then incorporate our estimates into a Fama and French (1992) asset-pricing framework. Our main result is that information does affect asset prices. A difference of 10 percentage points in the probability of information-based trading between two stocks leads to a difference in their expected returns of 2.5 percent per year. ASSET PRICING IS FUNDAMENTAL to our understanding of the wealth dynamics of an economy. This central importance has resulted in an extensive literature on asset pricing, much of it focusing on the economic factors that influence asset prices. Despite the fact that virtually all assets trade in markets, one set of factors not typically considered in asset-pricing models are the features of the markets in which the assets trade. Instead, the literature on asset pricing abstracts from the mechanics of asset price evolution, leaving unsettled the underlying question of how equilibrium prices are actually attained. Market microstructure, conversely, focuses on how the mechanics of the trading process affect the evolution of trading prices. A major focus of this extensive literature is on the process by which information is incorporated into prices. The microstructure literature provides structural models of how prices become efficient, as well as models of volatility, both issues clearly of importance for asset pricing. But of perhaps more importance, microstructure models pro

Risk Governance: Coping with Uncertainty in a Complex World

Abstract: �Risk Governance is a tour de force. Every risk manager, every risk analyst, every risk researcher must read this book - it is the demarcation point for all further advances in risk policy and risk research. Renn provides authoritative guidance on how to manage risks based on a definitive synthesis of the research literature. The skill with which he builds practical recommendations from solid science is unprecedented.� Thomas Dietz, Director, Environmental Science and Policy Program, Michigan State University, USA �A masterpiece of new knowledge and wisdom with illustrative examples of tested applications to realworld cases. The book is recommendable also to interested students in different disciplines as a timely textbook on 'risk beyond risk'.� Norio Okada, Full Professor and Director at the Disaster Prevention Research Institute (DPRI), Kyoto University, Japan �There are classic environmental works such as The Tragedy of the Commons by Hardin, Risk Society by Beck, The Theory of Communicative Action by Habermas, and the seminal volumes by Ostrom on governing the commons. Renn�s book fits right into this series of important milestones of environmental studies.� Jochen Jaeger, Professor at Concordia University, Montreal, Canada �Risk Governance provides a valuable survey of the whole field of risk and demonstrates how scientific, economic, political and civil society actors can participate in inclusive risk governance.� Jobst Conrad, Senior Scientist, Social Science Research Center Berlin, Germany �Renn offers a remarkably fair-minded and systematic approach to bringing together the diverse fields that have something to say about 'risk'. Risk Governance moves us along the path from the noisy, formative stage of thinking about risk to one with a stronger empirical, theoretical, and analytical foundation.� Baruch Fischhoff, PhD, Howard Heinz University Professor, Carnegie Mellon University, Pittsburgh, USA 'I cannot describe how impressed I am at the breadth and coherence of Renn's career's work! Written with remarkable clarity and minimal technical jargon... [this] should be required reading in risk courses!' John Graham, former director of the Harvard Risk Center and former deputy director of the Office of Budget and Management of the Unites States Administration This book, for the first time, brings together and updates the groundbreaking work of renowned risk theorist and researcher Ortwin Renn, integrating the major disciplinary concepts of risk in the social, engineering and natural sciences. The book opens with the context of risk handling before flowing through the core topics of assessment, evaluation, perception, management and communication, culminating in a look at the transition from risk management to risk governance and a glimpse at a new understanding of risk in (post)modern societies.

Coping with systems risk: security planning models for management decision making

Abstract: The likelihood that the firm's information systems are insufficiently protected against certain kinds of damage or loss is known as "systems risk." Risk can be managed or reduced when managers are aware of the full range of controls available and implement the most effective controls. Unfortunately, they often lack this knowledge, and their subsequent actions to cope with systems risk are less effective than they might otherwise be. This is one viable explanation for why losses from computer abuse and computer disasters today are uncomfortably large and still so potentially devastating after many years of attempting to deal with the problem. Results of comparative qualitative studies in two information services Fortune 500 firms identify an approach that can effectively deal with the problem. This theory-based security program includes (1) use of a security risk planning model, (2) education/training in security awareness, and (3) Countermeasure Matrix analysis.
