Book excerpt: Eric Barthalon applies the neglected theory of psychological time and memory decay of Nobel PrizeÐwinning economist Maurice Allais (1911Ð2010) to model investorsÕ psychology in the present context of recurrent financial crises. Shaped by the behavior of the demand for money during episodes of hyperinflation, AllaisÕs theory proves economic agents perceive the flow of clocksÕ time and forget the past at a context-dependent pace: rapidly in the presence of persistent and accelerating inflation and slowly in the event of the opposite situation. Barthalon recasts AllaisÕs work as a general theory of ÒexpectationsÓ under uncertainty, closing the gap between economic theory and investorsÕ behavior. Barthalon extends AllaisÕs theory to the field of financial instability, demonstrating its relevance to nominal interest rates in a variety of empirical scenarios and the positive nonlinear feedback that exists between asset price inflation and the demand for risky assets. Reviewing the works of the leading protagonists in the expectations controversy, Barthalon exposes the limitations of adaptive and rational expectations models and, by means of the perceived risk of loss, calls attention to the speculative bubbles that lacked the positive displacement discussed in KindlebergerÕs model of financial crises. He ultimately extrapolates Allaisian theory into a pragmatic approach to investor behavior and the natural instability of financial markets. He concludes with the policy implications for governments and regulators. Balanced and coherent, this book will be invaluable to researchers working in macreconomics, financial economics, behavioral finance, decision theory, and the history of economic thought.
