To understand business and its political, cultural, and economic context, it helps to view it historically, yet most business histories look no further back than the nineteenth century. The full sweep of business history actually begins much earlier, with the initial cities of Mesopotamia. In the first book to describe and explain these origins, Roberts depicts the society of ancient traders and consumers, tracing the roots of modern business and underscoring the relationship between early and modern business practice. Roberts's narrative begins before business, which he defines as selling to voluntary buyers at a profit. Before business, he shows, the material conditions and concepts for the pursuit of profit did not exist, even though trade and manufacturing took place. The earliest business, he suggests, arose with the long distance trade of early Mesopotamia, and expanded into retail, manufacturing and finance in these command economies, culminating in the Middle Eastern empires. (Part One) But it was the largely independent rise of business, money, and markets in classical Greece that produced business much as we know it. Alexander the Great's conquests and the societies that his successors created in their kingdoms brought a version of this system to the old Middle Eastern empires, and beyond. (Part Two) At Rome this entrepreneurial market system gained important new features, including business corporations, public contracting, and even shopping malls. The story concludes with the sharp decline of business after the 3rd century CE. (Part Three) In each part, Roberts portrays the major new types of business coming into existence. He weaves these descriptions into a narrative of how the prevailing political, economic, and social culture shaped the nature and importance of business and the status, wealth, and treatment of business people. Throughout, the discussion indicates how much (and how little) business has changed, provides a clear picture of what business actually is, presents a model for understanding the social impact of business as a whole, and yields stimulating insights for public policy today.

From the "guru to Wall Street's gurus" comes the fundamental techniques of value investing and their applications Bruce Greenwald is one of the leading authorities on value investing. Some of the savviest people on Wall Street have taken his Columbia Business School executive education course on the subject. Now this dynamic and popular teacher, with some colleagues, reveals the fundamental principles of value investing, the one investment technique that has proven itself consistently over time. After covering general techniques of value investing, the book proceeds to illustrate their applications through profiles of Warren Buffett, Michael Price, Mario Gabellio, and other successful value investors. A number of case studies highlight the techniques in practice. Bruce C. N. Greenwald (New York, NY) is the Robert Heilbrunn Professor of Finance and Asset Management at Columbia University. Judd Kahn, PhD (New York, NY), is a member of Morningside Value Investors. Paul D. Sonkin (New York, NY) is the investment manager of the Hummingbird Value Fund. Michael van Biema (New York, NY) is an Assistant Professor at the Graduate School of Business, Columbia University.

Accounting for Value teaches investors and analysts how to handle accounting in evaluating equity investments. The book's novel approach shows that valuation and accounting are much the same: valuation is actually a matter of accounting for value. Laying aside many of the tools of modern finance the cost-of-capital, the CAPM, and discounted cash flow analysis Stephen Penman returns to the common-sense principles that have long guided fundamental investing: price is what you pay but value is what you get; the risk in investing is the risk of paying too much; anchor on what you know rather than speculation; and beware of paying too much for speculative growth. Penman puts these ideas in touch with the quantification supplied by accounting, producing practical tools for the intelligent investor. Accounting for value provides protection from paying too much for a stock and clues the investor in to the likely return from buying growth. Strikingly, the analysis finesses the need to calculate a "cost-of-capital," which often frustrates the application of modern valuation techniques. Accounting for value recasts "value" versus "growth" investing and explains such curiosities as why earnings-to-price and book-to-price ratios predict stock returns. By the end of the book, Penman has the intelligent investor thinking like an intelligent accountant, better equipped to handle the bubbles and crashes of our time. For accounting regulators, Penman also prescribes a formula for intelligent accounting reform, engaging with such controversial issues as fair value accounting.

The substantially revised fourth edition of a widely used text, offering both an introduction to recursive methods and advanced material, mixing tools and sample applications. Recursive methods provide powerful ways to pose and solve problems in dynamic macroeconomics. Recursive Macroeconomic Theory offers both an introduction to recursive methods and more advanced material. Only practice in solving diverse problems fully conveys the advantages of the recursive approach, so the book provides many applications. This fourth edition features two new chapters and substantial revisions to other chapters that demonstrate the power of recursive methods. One new chapter applies the recursive approach to Ramsey taxation and sharply characterizes the time inconsistency of optimal policies. These insights are used in other chapters to simplify recursive formulations of Ramsey plans and credible government policies. The second new chapter explores the mechanics of matching models and identifies a common channel through which productivity shocks are magnified across a variety of matching models. Other chapters have been extended and refined. For example, there is new material on heterogeneous beliefs in both complete and incomplete markets models; and there is a deeper account of forces that shape aggregate labor supply elasticities in lifecycle models. The book is suitable for first- and second-year graduate courses in macroeconomics. Most chapters conclude with exercises; many exercises and examples use Matlab or Python computer programming languages.

The principles of value investing have resonated with savvy practitioners in the world of finance for a long time. In Creating Strategic Value, Joseph Calandro Jr. explores how the core ideas and methods of value investing can be profitably applied to corporate strategy and management. Calandro builds from an analysis of traditional value investing concepts to their strategic applications. He surveys value investing’s past, present, and future, drawing on influential texts, from Graham and Dodd’s time-tested works to more recent studies, to reveal potent managerial lessons. He explains the theoretical aspects of value investing-consistent approaches to corporate strategy and management and details how they can be successfully employed through practical case studies that demonstrate value realization in action. Calandro analyzes the applicability of key ideas such as the margin-of-safety principle to corporate strategy in a wide range of areas beyond stocks and bonds. He highlights the importance of an “information advantage”—knowing something that a firm’s competitors either do not know or choose to ignore—and explains how corporate managers can apply this key value investing differentiator. Offering expert insight into the use of time-tested value investing principles in new fields, Creating Strategic Value is an important book for corporate strategy and management practitioners at all levels as well as for students and researchers.

When an investor believes a stock is overvalued and will soon drop in price, he might decide to "short" it. First, he borrows an amount of the stock, and then sells it. He waits for the stock to tank before buying back the same amount of shares at a deflated price. After returning the shares to his lender, he pockets the difference—unless any one of several hard-to-predict variables interferes, and the stock fails to drop. Since these variables are so hard to predict, short selling is difficult for even seasoned investors. It takes great talent and experience to isolate the best short ideas for falling stocks—skills Amit Kumar developed and honed over decades of market analysis and trading. This book shares his short-selling framework, built on themes common to falling stocks and the market's endemic strengths and cycles. Featuring key case studies and exclusive interviews with successful fund managers Bill Ackman (Pershing Square Capital Management) and Mark Roberts (Off Wall Street Consulting Group), Kumar shows investors how to avoid traps and profit from well-researched short ideas. Investors may not always act on short ideas, but they can avoid losses by using Kumar's framework to identify overvalued stocks. Professionals and amateur investors alike will benefit from this fundamental research approach, which transforms short selling into a long-term strategy.

Roger Murray (1911–1998) was a crucial figure in the history of value investing. A financial professional, economist, adviser to members of Congress, and educator, Murray was the successor to the legendary Benjamin Graham as professor of the securities analysis course at Columbia Business School. There, he mentored generations of students, including Mario Gabelli, Charles Royce, Leon G. Cooperman, and Art Samberg. This book offers a compelling account of Murray’s multifaceted career alongside a series of remarkable lectures he gave late in his life that encapsulated his philosophy of investing. The investing professionals and educators Paul Johnson and Paul D. Sonkin chronicle Murray’s life and accomplishments, capturing his professional triumphs, theoretical insights, and lasting legacy. They highlight Murray’s educational philosophy and mentorship, including personal recollections from his students about his teaching and influence. The Enduring Value of Roger Murray features the transcripts of four lectures Murray gave in 1993, hosted by Gabelli, which became legendary in the investing community. These lectures inspired Bruce Greenwald to ask Murray to co-teach a security analysis course, leading to the resurrection of value investing education at Columbia Business School, which had waned after Murray’s retirement in 1977. Annotated by Johnson and Sonkin, these lectures are now available to a wide audience for the first time. They will be illuminating and instructive for all value investing students and practitioners today.
