Available in PDF, EPUB and Kindle. Book excerpt: This paper analyzes if and what kind of sovereign rating bias exists. We analyze three possible biases. Firstly, rating agencies may have the incentive to rate countries where they earn more money better compared to countries where they earn less (profit maximizing bias). Secondly, different information asymmetry levels between the rated sovereigns and the rating agencies could lead to a bias (information asymmetry bias). A third bias could be due to the fact that a rating agency applies higher ratings to a country with which the country where the rating agency is located has stronger relations (home country bias). For the analysis of a potential home country preference we use a novel approach to the existing financial literature on rating bias: in particular, we use variables proxying the interconnection between the country in which the rating agency is headquartered and the rated country. This paper finds no empirical evidence of profit maximizing bias on the level of sovereign ratings but a significant bias in sovereign ratings caused by information asymmetry. The results of the analysis of home country bias are ambiguous. The interconnection of the US with the rated country proxied by the trade channel does not imply any home country bias; nevertheless, when a different proxy -- based on the interconnection between US-financial institutions and the respective countries -- is used, at first glance the results indicate a bias with respect to the ratings from Moody's only. However, this finding turns out not to be robust.

Available in PDF, EPUB and Kindle. Book excerpt: There exist different kinds of biases in sovereign ratings. In this paper we analyze one of the possible rating biases, i.e. we examine if rating agencies may have the incentive to rate countries where they earn more money better compared to countries where they earn less (profit maximizing bias). This paper finds no empirical evidence of profit maximizing bias on the level of sovereign ratings: In the rating process for countries the reputational concerns seem to dominate over financial interests. To our knowledge, this paper is the first analysis examining the issue of profit maximizing bias on the sovereign level.

Download or read book Sovereign Debt and Rating Agency Bias written by D. Tennant and published by Springer. This book was released on 2017-08-15 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sovereign Debt and Credit Rating Bias rejects the notion that credit rating agencies' rigorous and transparent determination of ratings leaves no room for bias, and debunks the myth that the value CRAs place on their reputational capital precludes prolonged biases. To determine the extent of CRAs' biased actions, Tennant and Tracey apply a rigorous methodology to a well-established economic model of the determinants of sovereign debt quality. They present strong evidence of bias against poor countries and demonstrate how biased rating changes could disadvantage such countries and the companies operating therein as they seek access to international capital markets. They discuss plausible explanations for the bias and suggest remedial measures that would help ensure balance in credit rating changes. This book fills an important gap by rigorously examining a long-standing but often ignored concern about the rating practices of credit rating agencies.
Download or read book Sovereign Rating News and Financial Markets Spillovers written by Bertrand Candelon and published by International Monetary Fund. This book was released on 2011-03-01 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper examines the spillover effects of sovereign rating news on European financial markets during the period 2007-2010. Our main finding is that sovereign rating downgrades have statistically and economically significant spillover effects both across countries and financial markets. The sign and magnitude of the spillover effects depend both on the type of announcements, the source country experiencing the downgrade and the rating agency from which the announcements originates. However, we also find evidence that downgrades to near speculative grade ratings for relatively large economies such as Greece have a systematic spillover effects across Euro zone countries. Rating-based triggers used in banking regulation, CDS contracts, and investment mandates may help explain these results.

Download or read book To the Brink of Destruction written by Timothy J. Sinclair and published by Cornell University Press. This book was released on 2021-11-15 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: To the Brink of Destruction exposes how America's rating agencies helped generate the global financial crisis of 2007 and beyond, surviving and thriving in the aftermath. Despite widespread scrutiny, rating agencies continued to operate on the same business model and wield extraordinary power, exerting extensive influence over public policy. Timothy J. Sinclair brings the shadowy corners of this story to life by examining congressional testimony, showing how the wheels of accountability turned—and ultimately failed—during the crisis. He asks how and why the agencies risked their lucrative franchise by aligning so closely with a process of financial innovation that came undone during the crisis. What he finds is that key institutions, including the agencies, changed from being judges to being advocates years before the crisis, eliminating a vital safety valve meant to hinder financial excess. Sinclair's well-researched investigation offers a clear, accessible explanation of structured finance and how it works. To the Brink of Destruction avoids tired accusations, instead providing novel insight into the role rating agencies played in the worst crisis of modern global capitalism.
Download or read book Seller Reputation written by Heski Bar-Isaac and published by Now Publishers Inc. This book was released on 2008 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seller Reputation introduces a unifying framework that embeds a number of different approaches to seller reputation, incorporating both hidden information and hidden action. This framework is used to stress that the way in which consumers learn affects both behavior and outcomes. In particular, the extent to which information is generated and socially aggregated determines the efficiency of markets. After reviewing these theoretical building blocks, Seller Reputation examines several applications and empirical concerns. It highlights that the environment in which a transaction is embedded helps determine whether the transaction will occur and how parties will behave. Institutions, ranging from the design of online markets to norms in a community, can be understood as ensuring that concerns for reputation lead to more efficient outcomes. Similarly, the desire to affect consumer beliefs regarding the firm's incentives can help us understand strategic firm decisions that seem unrelated to the particular transactions they wish to promote. Seller Reputation concludes by considering slightly different models of reputation that lie beyond the scope of this framework, briefly reviewing the somewhat sparse empirical literature and suggesting future directions for research.
Download or read book Publication Bias in Meta Analysis written by Hannah R. Rothstein and published by John Wiley & Sons. This book was released on 2005-11-18 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Publication bias is the tendency to decide to publish a study based on the results of the study, rather than on the basis of its theoretical or methodological quality. It can arise from selective publication of favorable results, or of statistically significant results. This threatens the validity of conclusions drawn from reviews of published scientific research. Meta-analysis is now used in numerous scientific disciplines, summarizing quantitative evidence from multiple studies. If the literature being synthesised has been affected by publication bias, this in turn biases the meta-analytic results, potentially producing overstated conclusions. Publication Bias in Meta-Analysis examines the different types of publication bias, and presents the methods for estimating and reducing publication bias, or eliminating it altogether. Written by leading experts, adopting a practical and multidisciplinary approach. Provides comprehensive coverage of the topic including: Different types of publication bias, Mechanisms that may induce them, Empirical evidence for their existence, Statistical methods to address them, Ways in which they can be avoided. Features worked examples and common data sets throughout. Explains and compares all available software used for analysing and reducing publication bias. Accompanied by a website featuring software, data sets and further material. Publication Bias in Meta-Analysis adopts an inter-disciplinary approach and will make an excellent reference volume for any researchers and graduate students who conduct systematic reviews or meta-analyses. University and medical libraries, as well as pharmaceutical companies and government regulatory agencies, will also find this invaluable.
Download or read book Communities in Action written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2017-04-27 with total page 583 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the United States, some populations suffer from far greater disparities in health than others. Those disparities are caused not only by fundamental differences in health status across segments of the population, but also because of inequities in factors that impact health status, so-called determinants of health. Only part of an individual's health status depends on his or her behavior and choice; community-wide problems like poverty, unemployment, poor education, inadequate housing, poor public transportation, interpersonal violence, and decaying neighborhoods also contribute to health inequities, as well as the historic and ongoing interplay of structures, policies, and norms that shape lives. When these factors are not optimal in a community, it does not mean they are intractable: such inequities can be mitigated by social policies that can shape health in powerful ways. Communities in Action: Pathways to Health Equity seeks to delineate the causes of and the solutions to health inequities in the United States. This report focuses on what communities can do to promote health equity, what actions are needed by the many and varied stakeholders that are part of communities or support them, as well as the root causes and structural barriers that need to be overcome.

Download or read book The Optimism Bias written by Tali Sharot and published by Vintage. This book was released on 2011-06-14 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: Psychologists have long been aware that most people maintain an irrationally positive outlook on life—but why? Turns out, we might be hardwired that way. In this absorbing exploration, Tali Sharot—one of the most innovative neuroscientists at work today—demonstrates that optimism may be crucial to human existence. The Optimism Bias explores how the brain generates hope and what happens when it fails; how the brains of optimists and pessimists differ; why we are terrible at predicting what will make us happy; how emotions strengthen our ability to recollect; how anticipation and dread affect us; how our optimistic illusions affect our financial, professional, and emotional decisions; and more. Drawing on cutting-edge science, The Optimism Bias provides us with startling new insight into the workings of the brain and the major role that optimism plays in determining how we live our lives.
Download or read book A Century of Sovereign Ratings written by Norbert Gaillard and published by Springer Science & Business Media. This book was released on 2011-09-21 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The financial difficulties experienced by Greece since 2009 serve as a reminder that countries (i.e., sovereigns) may default on their debt. Many observers considered the financial turmoil was behind us because major advanced countries had adopted stimulus packages to prevent banks from going bankrupt. However, there are rising doubts about the creditworthiness of several advanced countries that participated in the bailouts. In this uncertain context, it is particularly crucial to be knowledgeable about sovereign ratings. This book provides the necessary broad overview, which will be of interest to both economists and investors alike. Chapter 1 presents the main issues that are addressed in this book. Chapters 2, 3, and 4 provide the key notions to understand sovereign ratings. Chapter 2 presents an overview of sovereign rating activity since the first such ratings were assigned in 1918. Chapter 3 analyzes the meaning of sovereign ratings and the significance of rating scales; it also describes the refinement of credit rating policies and tools. Chapter 4 focuses on the sovereign rating process. Chapters 5 and 6 open the black box of sovereign ratings. Chapter 5 compares sovereign rating methodologies in the interwar years with those in the modern era. After examining how rating agencies have amended their methodologies since the 1990s, Chapter 6 scrutinizes rating disagreements between credit rating agencies (CRAs). Chapters 7 and 8 measure the performances of sovereign ratings by computing default rates and accuracy ratios: Chapter 7 looks at the interwar years and Chapter 8 at the modern era. The two chapters assess which CRA assigns the most accurate ratings during the respective periods. Chapters 9 and 10 compare the perception of sovereign risk by the CRAs and market participants. Chapter 9 focuses on the relation between JP Morgan Emerging Markets Bond Index Global spreads and emerging countries’ sovereign ratings for the period 1993–2007. Chapter 10 compares the eurozone members’ sovereign ratings with Credit Default Swap-Implied Ratings (CDS-IRs) during the Greek debt crisis of November 2009–May 2010.

Download or read book Evidence Based Health Informatics written by E. Ammenwerth and published by IOS Press. This book was released on 2016-05-20 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Health IT is a major field of investment in support of healthcare delivery, but patients and professionals tend to have systems imposed upon them by organizational policy or as a result of even higher policy decision. And, while many health IT systems are efficient and welcomed by their users, and are essential to modern healthcare, this is not the case for all. Unfortunately, some systems cause user frustration and result in inefficiency in use, and a few are known to have inconvenienced patients or even caused harm, including the occasional death. This book seeks to answer the need for better understanding of the importance of robust evidence to support health IT and to optimize investment in it; to give insight into health IT evidence and evaluation as its primary source; and to promote health informatics as an underpinning science demonstrating the same ethical rigour and proof of net benefit as is expected of other applied health technologies. The book is divided into three parts: the context and importance of evidence-based health informatics; methodological considerations of health IT evaluation as the source of evidence; and ensuring the relevance and application of evidence. A number of cross cutting themes emerge in each of these sections. This book seeks to inform the reader on the wide range of knowledge available, and the appropriateness of its use according to the circumstances. It is aimed at a wide readership and will be of interest to health policymakers, clinicians, health informaticians, the academic health informatics community, members of patient and policy organisations, and members of the vendor industry.

Book excerpt: Ratings, Rating Agencies and the Global Financial System brings together the research of economists at New York University and the University of Maryland, along with those from the private sector, government bodies, and other universities. The first section of the volume focuses on the historical origins of the credit rating business and its present day industrial organization structure. The second section presents several empirical studies crafted largely around individual firm-level or bank-level data. These studies examine (a) the relationship between ratings and the default and recovery experience of corporate borrowers, (b) the comparability of credit ratings made by domestic and foreign rating agencies, and (c) the usefulness of financial market indicators for rating banks, among other topics. In the third section, the record of sovereign credit ratings in predicting financial crises and the reaction of financial markets to changes in credit ratings is examined. The final section of the volume emphasizes policy issues now facing regulators and credit rating agencies.
