Based on a formal six-step process for analysis and decision-making, this book employees an external focus, with particular emphasis on credit and equity investment decisions.  This concise yet comprehensive treatment of the subject covers financial statements, accounting information, stock market information, economic and industry information, and other sources for recommendations and decisions.  Assuming a reasonable understanding of basic accounting and finance principles the book expands from these principles to structure financial analysis for specific recommendations or decisions.

This book examines the origins of modern corporate finance systems during the rapid industrialization period leading up to World War I. The study leads to three sets of conclusions. First, modern financial systems are rooted in the past, are idiosyncratic to specific countries, and are highly path-dependent. Therefore, to understand current financial institutions, we must take stock of the forces at play in the near and distant past: political and regulatory intervention, natural resource endowments, educational institutions, and social and religious beliefs. Second, financial institutions and markets do not create economic growth without significant first steps in industrial development and supporting institutions. The finance-growth relationship also varies over time, as financial and economic developments influence one another and create a feedback mechanism. Third, and most important from the modern policy standpoint, there is no one-size-fits-all solution to financial system design and industrial development. Having specific types of financial institutions is far less important than developing a strong, stable, and legally protected financial system with a rich diversity of institutions and vibrant markets that can adapt to changing needs."

The authors, both experienced fraud examiners, have spent decades investigating fraud, as well as developing strategies to prevent it. This book is an essential tool in creating an anti-fraud environment in any company." James D. Ratley, CFE, President & CEO, Association of Certified Fraud Examiners "Biegelman and Bartow's Executive Roadmap to Fraud Prevention and Internal Control is an essential guide for all who have an interest in eradicating corporate or institutional fraud.

Martin Biegelman and Joel Bartow have accomplished an incredible achievement: they have flawlessly bridged the chasm between the theoretical/academic and practical/tangible. This is a volume that should not be on the bookshelf of every manager interested in compliance and fraud prevention (which should be every manager); it should be dog-eared and open on the desktop of every such manager! Kudos to Messrs. Biegelman and Bartow!" William J. Kresse, M.S., J.D., CPA, CFF, CFE; Associate Professor, Graham School of Management; Director, Center for the Study of Fraud and Corruption, Saint Xavier University, Chicago "Biegelman and Bartow have again provided an invaluable resource for leaders in the corporate world who have responsibility for fraud, integrity, and compliance.

Fisher, PhD, CPA, Associate Professor and Chair of the Department of Accounting and Law, The University at Albany-SUNY "The book's exploration of fraud theories ranging from 'rotten apple' to the 'potato chip' (can't eat just one!), provides useful examination of the psychology of corporate fraud that explains its recurring nature and offers clues to creating a fraud resistant culture."

It's not all about the money; the key to true riches

Leo Tolstoy said, "Nobody knows where the human race is going. The highest wisdom, then, is to know where you are going." Yet many today chase the false rabbits of success: status, luxury, reputation and material possessions. In the quest to "have it all," our lives often lack real meaning and purpose. "Beyond Wealth" is the antidote.

"New York Times" bestselling author Alexander Green takes things right down to brass tacks: We are here for a short time. Knowledge is limitless. Therefore, the most critical knowledge is not any particular skill but rather wisdom about "how to live." Fortunately, men and women have had several thousand years to think about what it means to live "the good life." And the answers found here, from Plato and Aristotle to Mahatma Gandhi and Stephen Hawking, will both surprise and delight you.

"Beyond Wealth" provides insightful commentary on the most important aspects of our lives: love, work, honor, trust, freedom, death, fear, truth, beauty and other timeless issues. The book is both a thought provoking read and the ideal gift, guaranteed to ennoble, uplift and inspire.

"Analysis of Financial Data" teaches the basic methods and techniques of data analysis to finance students, by showing them how to apply such techniques in the context of real world empirical problems.

This title includes key features such as: coverage of many of the major tools used by the financial economist e.g. correlation, regression, time series analysis and methods for analyzing financial volatility; extensive use of real data examples, which involves readers in hands on computer work; and, mathematical techniques at a level suited to MBA students and undergraduates taking a first course in the topic. Supplementary material for readers and lecturers are provided on an accompanying website.

A DETAILED PRIMER ON TODAY'S MOST SOPHISTICATED AND CONTROVERSIAL TRADING TECHNIQUE

Traditional economic theory studies idealized markets in which prices alone can guide efficient allocation, with no need for central organization. Such models build from Adam Smith's famous concept of an invisible hand, which guides markets and renders regulation or interference largely unnecessary. Yet for many markets, prices alone are not enough to guide feasible and efficient outcomes, and regulation alone is not enough, either. Consider air traffic control at major airports. While prices could encourage airlines to take off and land at less congested times, prices alone do just part of the job; an air traffic control system is still indispensable to avoid disastrous consequences. With just an air traffic controller, however, limited resources can be wasted or poorly used. What's needed in this and many other real-world cases is an auction system that can effectively reveal prices while still maintaining enough direct control to ensure that complex constraints are satisfied. In Discovering Prices, Paul Milgrom-the world's most frequently cited academic expert on auction design-describes how auctions can be used to discover prices and guide efficient resource allocations, even when resources are diverse, constraints are critical, and market-clearing prices may not even exist. Economists have long understood that externalities and market power both necessitate market organization. In this book, Milgrom introduces complex constraints as another reason for market design. Both lively and technical, Milgrom roots his new theories in real-world examples (including the ambitious U.S. incentive auction of radio frequencies, whose design he led) and provides economists with crucial new tools for dealing with the world's growing complex resource-allocation problems.

Do your students struggle to engage with legal topics? Look no further than Marson & Ferris' Business Law to help them actively engage with the law, understand it, and approach it with confidence. Written with business, management, and finance and accounting students in mind, the authors put the law into a context that they can easily understand by introducing case studies in every chapter. 'Business Scenarios' help the students contextualize the law by presenting the reader with an example of an everyday problem which demonstrates how the law can affect a company, employer, employee, or other individual. Throughout each chapter the students are asked to pause and consider how the content applies to these routine business problems, enabling them to become active readers and think independently about how the law operates. The first chapter provides a helpful guide to studying the law and advice on how to excel in assessments so that students can fulfil their potential. This chapter includes a sample problem question and model answer. Further sample problem and essay questions can be found at the end of chapters, giving readers an opportunity to test their understanding and practise for assessments. Students will be able to find indicative answers to these questions hosted with the online resources for this book. At the end of each chapter the authors provide further reading suggestions to guide students that want to deepen their knowledge, including well-maintained and trusted websites, Twitter feeds, and YouTube channels in addition to suitable books and articles. Digital formats and resources This edition is available for students and institutions to purchase in a variety of formats, and is supported by online resources. - The e-book offers a mobile experience and convenient access along with functionality tools, navigation features, and links that offer extra learning support: www.oxfordtextbooks.co.uk/ebooks - The online resources include flashcard cases, self-test questions and answers with feedback, and additional material on legislation.

Among the symmetrical distributions with an infinite domain, the most popular alternative to the normal variant is the logistic distribution as well as the Laplace or the double exponential distribution, which was first introduced in 1774. Occasionally, the Cauchy distribution is also used. Surprisingly, the hyperbolic secant distribution has led a charmed life, although Manoukian and Nadeau had already stated in 1988 that "... the hyperbolic-secant distribution ... has not received sufficient attention in the published literature and may be useful for students and practitioners." During the last few years, however, several generalizations of the hyperbolic secant distribution have become popular in the context of financial return data because of its excellent fit. Nearly all of them are summarized within this Springer Brief.

Focusing on recent advances in option pricing under the SABR model, this book shows how to price options under this model in an arbitrage-free, theoretically consistent manner. It extends SABR to a negative rates environment, and shows how to generalize it to a similar model with additional degrees of freedom, allowing simultaneous model calibration to swaptions and CMSs. Since the SABR model is used on practically every trading floor to construct interest rate options volatility cubes in an arbitrage-free manner, a careful treatment of it is extremely important. The book will be of interest to experienced industry practitioners, as well as to students and professors in academia. Aimed mainly at financial industry practitioners (for example quants and former physicists) this book will also be interesting to mathematicians who seek intuition in the mathematical finance.

Lex Fullarton's book "Heat, Dust and Taxes: A story of tax schemes in Australia's outback" set in the picturesque but treacherous landscape in the Outback of North-western Australia, tells the story of one of the greatest series of tax avoidance schemes in history. This book is not only an interesting read, it makes a significant contribution to our understanding of taxpayer compliance behaviour development in the highly problematic area of mass marketed tax schemes. Dr Paul Kenny, Associate Professor in Taxation Law, Flinders University, Flinders Business School

This book introduces the main theoretical findings related to copulas and shows how statistical modeling of multivariate continuous distributions using copulas can be carried out in the R statistical environment with the package copula (among others). Copulas are multivariate distribution functions with standard uniform univariate margins. They are increasingly applied to modeling dependence among random variables in fields such as risk management, actuarial science, insurance, finance, engineering, hydrology, climatology, and meteorology, to name a few. In the spirit of the Use R! series, each chapter combines key theoretical definitions or results with illustrations in R. Aimed at statisticians, actuaries, risk managers, engineers and environmental scientists wanting to learn about the theory and practice of copula modeling using R without an overwhelming amount of mathematics, the book can also be used for teaching a course on copula modeling.

"University endowment managers have generally outperformed the market benchmarks. However, their knowledge has not been well documented in any book. This book fills that gap and should be of significant help to all those who want to learn from extensive interviews with a number of endowment managers."--PREM JAIN, McDonough Professor of Accounting and Finance, Georgetown University

Learn how higher education's largest endowments consistently achieve higher investment returns than the overall market.

The Chief Investment Officers who oversee the top academic endowment funds manage over $400 billion in total assets. Over the last ten years (1999-2009), large endowments returned an average of 6.1%, compared to the S&P 500 index average of -2.22%, an outperformance difference of over 8%. With the recent sharp economic downturn, and a decade of inflation-adjusted flat returns in the overall equities market, institutional and individual investors alike are looking to endowments for proven strategies for improving the performance of their portfolios. "Outperform: Inside the Investment Strategy of Billion Dollar Endowments" interviews top CIOs from leading endowments, to detail how they consistently outperform the market, what they predict for the coming years, and how small investors can employ their investment philosophies.

Mutual funds form the bedrock of retirement savings in the United States, and, considering their rapid growth, are sure to be more critical in the future. Because the size of fees paid by investors to mutual fund advisers can strongly affect the return on investment, these fees have become a contentious issue in Congress and the courts, with many arguing that investment advisers grow rich at the expense of investors.

This ground-breaking book not only conceptualizes a new economic model of the mutual fund industry, but also uses this model to test for price competition between investment advisers, evaluating the assertion that market forces fail to protect investors' returns from excessive fees. Highly experienced authors track the growth of the industry over the past twenty-five years and present arguments and evidence both for and against theories of adviser malfeasance. The authors review the regulatory history of mutual fund fees and summarize leading case decisions addressing excessive fees.

Revealing the extent to which the governance structure of mutual funds truly impacts fund performance, this book provides the best understanding of today's mutual fund industry and is a vital tool for investors, money managers, fund directors, securities lawyers, economists, and anyone concerned with the regulation of mutual funds.

Nearly seventy years after the last great stock market bubble and crash, another bubble emerged and burst, despite a thick layer of regulation designed since the 1930s to prevent such things. This time the bubble was enormous, reflecting nearly twenty years of double-digit stock market growth, and its bursting had painful consequence. The search for culprits soon began, and many were discovered, including not only a number of overreaching corporations, but also their auditors, investment bankers, lawyers and indeed, their investors. In Governing the Modern Corporation, Smith and Walter analyze the structure of market capitalism to see what went wrong.
They begin by examining the developments that have made modern financial markets--now capitalized globally at about $70 trillion--so enormous, so volatile and such a source of wealth (and temptation) for all players. Then they report on the evolving role and function of the business corporation, the duties of its officers and directors and the power of its Chief Executive Officer who seeks to manage the company to achieve as favorable a stock price as possible.
They next turn to the investing market itself, which comprises mainly financial institutions that own about two-thirds of all American stocks and trade about 90% of these stocks. These investors are well informed, highly trained professionals capable of making intelligent investment decisions on behalf of their clients, yet the best and brightest ultimately succumbed to the bubble and failed to carry out an appropriate governance role.
In what follows, the roles and business practices of the principal financial intermediaries--notably auditors and bankers--areexamined in detail. All, corporations, investors and intermediaries, are found to have been infected by deep-seated conflicts of interest, which add significant agency costs to the free-market system. The imperfect, politicized role of the regulators is also explored, with disappointing results. The entire system is seen to have been compromised by a variety of bacteria that crept in, little by little, over the years and were virtually invisible during the bubble years.
These issues are now being addressed, in part by new regulation, in part by prosecutions and class action lawsuits, and in part by market forces responding to revelations of misconduct. But the authors note that all of the market's professional players--executives, investors, experts and intermediaries themselves--carry fiduciary obligations to the shareholders, clients, and investors whom they represent. More has to be done to find ways for these fiduciaries to be held accountable for the correct discharge of their duties.
