Manufacturing Morals


Book Description

Corporate accountability is never far from the front page, and as one of the world’s most elite business schools, Harvard Business School trains many of the future leaders of Fortune 500 companies. But how does HBS formally and informally ensure faculty and students embrace proper business standards? Relying on his first-hand experience as a Harvard Business School faculty member, Michel Anteby takes readers inside HBS in order to draw vivid parallels between the socialization of faculty and of students. In an era when many organizations are focused on principles of responsibility, Harvard Business School has long tried to promote better business standards. Anteby’s rich account reveals the surprising role of silence and ambiguity in HBS’s process of codifying morals and business values. As Anteby describes, at HBS specifics are often left unspoken; for example, teaching notes given to faculty provide much guidance on how to teach but are largely silent on what to teach. Manufacturing Morals demonstrates how faculty and students are exposed to a system that operates on open-ended directives that require significant decision-making on the part of those involved, with little overt guidance from the hierarchy. Anteby suggests that this model—which tolerates moral complexity—is perhaps one of the few that can adapt and endure over time. Manufacturing Morals is a perceptive must-read for anyone looking for insight into the moral decision-making of today’s business leaders and those influenced by and working for them.




The Elusive Quest for Growth


Book Description

Why economists' attempts to help poorer countries improve their economic well-being have failed. Since the end of World War II, economists have tried to figure out how poor countries in the tropics could attain standards of living approaching those of countries in Europe and North America. Attempted remedies have included providing foreign aid, investing in machines, fostering education, controlling population growth, and making aid loans as well as forgiving those loans on condition of reforms. None of these solutions has delivered as promised. The problem is not the failure of economics, William Easterly argues, but the failure to apply economic principles to practical policy work. In this book Easterly shows how these solutions all violate the basic principle of economics, that people—private individuals and businesses, government officials, even aid donors—respond to incentives. Easterly first discusses the importance of growth. He then analyzes the development solutions that have failed. Finally, he suggests alternative approaches to the problem. Written in an accessible, at times irreverent, style, Easterly's book combines modern growth theory with anecdotes from his fieldwork for the World Bank.




In the Long Run We Are All Dead


Book Description

A groundbreaking debunking of moderate attempts to resolve financial crises In the ruins of the 2007–2008 financial crisis, self-proclaimed progressives the world over clamored to resurrect the economic theory of John Maynard Keynes. The crisis seemed to expose the disaster of small-state, free-market liberalization and deregulation. Keynesian political economy, in contrast, could put the state back at the heart of the economy and arm it with the knowledge needed to rescue us. But what it was supposed to rescue us from was not so clear. Was it the end of capitalism or the end of the world? For Keynesianism, the answer is both. Keynesians are not and never have been out to save capitalism, but rather to save civilization from itself. It is political economy, they promise, for the world in which we actually live: a world in which prices are “sticky,” information is “asymmetrical,” and uncertainty inescapable. In this world, things will definitely not take care of themselves in the long run. Poverty is ineradicable, markets fail, and revolutions lead to tyranny. Keynesianism is thus modern liberalism’s most persuasive internal critique, meeting two centuries of crisis with a proposal for capital without capitalism and revolution without revolutionaries. If our current crises have renewed Keynesianism for so many, it is less because the present is worth saving, than because the future seems out of control. In that situation, Keynesianism is a perfect fit: a faith for the faithless.




The Speculation Economy


Book Description

The first book to reveal the deep historical roots of the modern corporate obsession with stock price - a major cause of recent scandals like those at Enron and WorldComDetails how the rise of the modern corporation created the modern stock market - and why this led to an economy dominated by stock speculationAmerican companies once focused exclusively on providing the best products and services. But today, most corporations are obsessed with maximizing their stock prices, resulting in short-term thinking and the kind of cook-the-books corruption seen in the Enron and WorldCom scandals. How did this happen?In this groundbreaking book, Lawrence E. Mitchell traces the origins of the problem to the first decade of the 20th century, when industrialists and bankers began merging existing companies into huge ''combines''- today's giant corporations - so they could profit by manufacturing and selling stock in these new entities. He describes and analyzes the legal changes that made this possible, the federal regulatory efforts that missed the significance of this transforming development, and the changes in American society and culture that led more and more Americans to enter the market, turning from relatively safe bonds to riskier common stock in the hopes of becoming rich. Financiers and the corporations they controlled encouraged this trend, but as stock ownership expanded and businesses were increasingly forced to cater to stockholders' ''get rich quick'' expectations, a subtle but revolutionary shift in the nature of the American economy occurred: finance no longer served industry; instead, industry began to serve finance.The Speculation Economy analyzes the history behind the opening of this economic Pandora's box, the root cause of so many modern acts of corporate malfeasance.




Advances in Behavioral Finance


Book Description

Modern financial markets offer the real world's best approximation to the idealized price auction market envisioned in economic theory. Nevertheless, as the increasingly exquisite and detailed financial data demonstrate, financial markets often fail to behave as they should if trading were truly dominated by the fully rational investors that populate financial theories. These markets anomalies have spawned a new approach to finance, one which as editor Richard Thaler puts it, "entertains the possibility that some agents in the economy behave less than fully rationally some of the time." Advances in Behavioral Finance collects together twenty-one recent articles that illustrate the power of this approach. These papers demonstrate how specific departures from fully rational decision making by individual market agents can provide explanations of otherwise puzzling market phenomena. To take several examples, Werner De Bondt and Thaler find an explanation for superior price performance of firms with poor recent earnings histories in the tendencies of investors to overreact to recent information. Richard Roll traces the negative effects of corporate takeovers on the stock prices of the acquiring firms to the overconfidence of managers, who fail to recognize the contributions of chance to their past successes. Andrei Shleifer and Robert Vishny show how the difficulty of establishing a reliable reputation for correctly assessing the value of long term capital projects can lead investment analysis, and hence corporate managers, to focus myopically on short term returns. As a testing ground for assessing the empirical accuracy of behavioral theories, the successful studies in this landmark collection reach beyond the world of finance to suggest, very powerfully, the importance of pursuing behavioral approaches to other areas of economic life. Advances in Behavioral Finance is a solid beachhead for behavioral work in the financial arena and a clear promise of wider application for behavioral economics in the future.
