Speculation, Trading, and Bubbles


Book Description

As long as there have been financial markets, there have been bubbles—those moments in which asset prices inflate far beyond their intrinsic value, often with ruinous results. Yet economists are slow to agree on the underlying forces behind these events. In this book José A. Scheinkman offers new insight into the mystery of bubbles. Noting some general characteristics of bubbles—such as the rise in trading volume and the coincidence between increases in supply and bubble implosions—Scheinkman offers a model, based on differences in beliefs among investors, that explains these observations. Other top economists also offer their own thoughts on the issue: Sanford J. Grossman and Patrick Bolton expand on Scheinkman's discussion by looking at factors that contribute to bubbles—such as excessive leverage, overconfidence, mania, and panic in speculative markets—and Kenneth J. Arrow and Joseph E. Stiglitz contextualize Scheinkman's findings.




The Art Of Speculation


Book Description

Philip L. Carret (1896-1998) was a famed investor and founder of The Pioneer Fund (Fidelity Mutual Trust), one of the first Mutual Funds in the United States. A former Barron’s reporter and WWI aviator, Carret launched the Mutual Trust in 1928 after managing money for his friends and family. The initial effort evolved into Pioneer Investments. He ran the fund for 55 years, during which an investment of $10,000 became $8 million. Warren Buffett said of him that he had “the best long term investment record of anyone I know” He is most famous for the long successful track record he achieved investing in Common Stocks and for being one of Warren Buffett’s role models. This book comprises a series of articles written for Barron’s and published in book form in 1930.—Print Ed.







The Foreign Exchange Market


Book Description

The flotation of exchange rates in the early 1970s saw a significant increase in the importance of foreign exchange markets and in the interest shown in them. Apart from the consequent institutional changes, this period also witnessed a revolution in macroeconomic analysis and finance theory based on the concept of rational expectations. This book provides an integrated approach to recent developments in the understanding of foreign exchange markets. It begins by charting the institutional background and looks at the recent history of movements in some of the major exchange rates. The theoretical sections focus on the economic and finance theory of the asset market approach, the macroeconomic models developed from this approach, and on interest rate parity theory. The empirical chapters draw on the authors' own research from a high quality set of exchange rate and interest rate data. The statistical properties of exchange rates are analysed; the relationship between spot and forward rates is examined; and the modelling and impact of new information on the forward and spot relationship is considered. The final chapter is devoted to the estimation and testing of exchange rate models.




Speculation


Book Description

In the modern world, why do we still resort to speculation? Advances in scientific and statistical reasoning are supposed to have provided greater certainty in making claims about the future. Yet we constantly spin out scenarios about tomorrow, for ourselves or for entire societies, with flimsy or no evidence. Insubstantial speculations—from utopian thinking to high-risk stock gambles—often provoke fierce backlash, even when they prove prophetic for the world we come to inhabit. Why does this hypothetical way of thinking generate such controversy? In this cultural, literary, and intellectual history, Gayle Rogers traces debates over speculation from antiquity to the present. Celebrated by Boethius as the height of humanity’s mental powers but denigrated as sinful by John Calvin, speculation eventually became central to the scientific revolution’s new methods of seeing the natural world. In the nineteenth century, writers such as Jane Austen used the concept to diagnose the marriage market, redefining speculation for the purpose of social critique. Speculation fueled the development of modern capitalism, spurring booms, busts, and bubbles, and recently artificial intelligence has automated the speculation previously done by humans, with uncertain and troubling consequences. Unraveling these histories and many other disputes, Rogers argues that what has always been at stake in arguments over speculation, and why it so often appears so threatening, is the authority to produce and control knowledge about the future. Recasting centuries of contests over the power to anticipate tomorrow, this book reveals the crucial role speculation has played in how we create—and potentially destroy—the future.







Foreign Exchange Intervention Rules for Central Banks: A Risk-based Framework


Book Description

This paper presents a rule for foreign exchange interventions (FXI), designed to preserve financial stability in floating exchange rate arrangements. The FXI rule addresses a market failure: the absence of hedging solution for tail exchange rate risk in the market (i.e. high volatility). Market impairment or overshoot of exchange rate between two equilibria could generate high volatility and threaten financial stability due to unhedged exposure to exchange rate risk in the economy. The rule uses the concept of Value at Risk (VaR) to define FXI triggers. While it provides to the market a hedge against tail risk, the rule allows the exchange rate to smoothly adjust to new equilibria. In addition, the rule is budget neutral over the medium term, encourages a prudent risk management in the market, and is more resilient to speculative attacks than other rules, such as fixed-volatility rules. The empirical methodology is backtested on Banco Mexico’s FXIs data between 2008 and 2016.

Intervention to Save Hong Kong


Book Description

By August 1998, the Hong Kong economy had become threatened not only by the natural consequences of the Asian crisis (1997-98), but also by waves of speculation, betting that the authorities would be forced to abandon the linked exchange rate (to the US dollar). When facing previous speculative attacks (starting October 1997), the authorities had followed traditional policies of raising interest rates. But by August 1998, such policies had helped to batter asset markets; property prices and output were falling, and confidence was low. Moreover, the speculators had developed an ingenious 'double play', simultaneously selling both the foreign exchange market and the Hang Seng equity market short; whether the authorities used an interest rate defense, or abandoned the 'link', the speculators would gain either way. So, the authorities decided on a bold, unexpected and unconventional response to reports of a further attack. They would undertake counter-intervention, again both in the equity and foreign exchange markets. This book provides a fascinating story in itself, and insights into what lessons academics and practitioners can learn from the turbulent events of the time.




The Behavioral Economics of Foreign Exchange Markets


Book Description

This book deals with psychological factors, which may be important for understanding the observable exchange rate movements. Thus, the study belongs to the new research field of behavioral economics, which considers the relevance of psychological factors in economic contexts. The main objective of behavioral economists is to develop a more realistic view of the actual human behavior in the context of economics. Central to the concept of behavioral economics is the assumption that humans' actual behavior deviates from the ideal of economic rationality due to at least two reasons: first, decisions are usually based on an incomplete information basis and, second, the information processing of human beings is limited by their computational capacities. Due to these limitations people are forced to apply simple heuristics in information processing. Our aim is to analyze the relevance of simple heuristics in the context of foreign exchange markets. In our view, the decision situation in foreign exchange markets can serve as a prime example for decision situations in which simple heuristics are especially relevant as the complexity of the decision situation is very high.
