Book Description
In this paper, we provide an equilibrium explanation for the observed optimism in analysts' earnings forecasts. Our analysis provides theoretical support to the widely held notion that analysts engage in earnings optimism to gain access to management's private information. We show that a strategic analyst, who is motivated by improving the combined accuracy of his forecasts, issues a biased initial forecast to extract information from management, but issues unbiased forecasts subsequently. The management, on the other hand, provides more access because this optimistic bias reduces the proprietary costs associated with disclosure at the margin. An important element of our model is the assumption that analysts also have private information relevant to assessing firm value. Despite rational expectations about analyst bias, analysts' private information cannot be fully unravelled by other agents due to the noise introduced by the diversity in analysts' incentives.

Book Description
Analyst forecasting bias is frequently attributed to opportunism. We argue that opportunism is not a necessary condition for bias and propose a simple model, based on research in behavioral economics and psychology, of belief-based probability weighting. The model is used to develop benchmarks which we test empirically. Our model explains the change in the magnitude of forecast bias over the forecast horizon, the percentage of optimistic and pessimistic forecast errors at long horizons, and seemingly counter-intuitive findings around the implementation of Regulation Fair Disclosure. Our results may inform regulators as they attempt to reduce or eliminate analyst forecast bias; eliminating incentives to bias may not lead to statistically unbiased forecasts.

Book Description
We show that understanding the role of analysts' forecast bias is central to discovering the behavior that causes some stocks to have high analyst forecast dispersion. This finding is important because stocks with high analyst forecast dispersion contribute significantly to many important anomalies. We first explain how forecast bias produces significant negative future returns in the high dispersion portfolio. Next we examine the effect of these stocks on momentum returns, the profitability anomaly, and post-earnings announcement drift. Finally, we examine the performance of four asset pricing models focusing on the model's ability to explain the returns to these high dispersion stocks.

Book Description
This study models the interaction between a sell-side analyst and risk-averse investors. It derives an analyst's optimal earnings forecast and investors' optimal trading decisions in a setting where the analyst's payoff depends on the trading volume the forecast generates as well as on the forecast error. In the fully separating equilibrium, we find that the analyst biases the forecast upward (downward) if his private signal reveals relatively good (bad) news.The model predicts that: (i) the analyst biases the forecast upward more often than downward and the forecast is on average optimistic; (ii) the magnitude of the analyst's bias is increasing in the per share benefit from trading volume he receives; and (iii) the analyst's expected squared forecast error may increase in the precision of his private information. Finally, we characterize the circumstances under which the (rational) analyst acts as if he overweights or underweights his private information.

Book Description
Technological innovations are key causal agents of surprise and disruption. In the recent past, the United States military has encountered unexpected challenges in the battlefield due in part to the adversary's incorporation of technologies not traditionally associated with weaponry. Recognizing the need to broaden the scope of current technology forecasting efforts, the Office of the Director, Defense Research and Engineering (DDR&E) and the Defense Intelligence Agency (DIA) tasked the Committee for Forecasting Future Disruptive Technologies with providing guidance and insight on how to build a persistent forecasting system to predict, analyze, and reduce the impact of the most dramatically disruptive technologies. The first of two reports, this volume analyzes existing forecasting methods and processes. It then outlines the necessary characteristics of a comprehensive forecasting system that integrates data from diverse sources to identify potentially game-changing technological innovations and facilitates informed decision making by policymakers. The committee's goal was to help the reader understand current forecasting methodologies, the nature of disruptive technologies and the characteristics of a persistent forecasting system for disruptive technology. Persistent Forecasting of Disruptive Technologies is a useful text for the Department of Defense, Homeland Security, the Intelligence community and other defense agencies across the nation.

Book Description
If either economic incentives or psychological phenomena cause the bias in analysts' forecasts to persist long enough, it would be potentially discoverable and exploitable by investors. quot;Exploitationquot; in this context implies that investors, through examination of historical forecasting performance, can more or less reliably estimate the direction and extent of bias, and impute unbiased estimates for themselves, given analysts' forecasts. The absence of persistence in forecast errors would suggest that analysts' own behavior ultimately quot;self-correctsquot; within a time frame that eliminates the possibility that the patterns could be exploited by investors. We use two look-back methods that capture salient features of analysts' past forecasting behavior to form quintile portfolios that describe the range of analysts' forecasting behavior. Parametric and nonparametric tests are performed to determine whether the two portfolio formation methods provide predictive power with respect to subsequent forecast errors. The findings support a conclusion that analysts' behaviors in both optimistic and pessimistic extremes do not entirely self-correct, leaving open the possibility that investors may find historical forecast errors useful in making inferences about current forecasts.
