Book Description
In modeling a combination of forecasts all the information related to the past performance of the individual forecasts, including accuracy and correlation, is considered. In this paper I have extended the modeling to incorporate a rank ordering of the forecasts by a decision maker. This ordering could be based on the expectations of a decision maker or on the judgment of an expert about the relative future performance of the forecasts. The problem is set up as a likelihood function of the individual forecasts given the combined forecast. It is shown that this likelihood function is approximately an exponential function of a relative entropy information measure. The maximum likelihood combined forecast is a weighted linear function of the individual forecasts, where the weights are a function of the past performance of the individual forecasts, the correlations between the forecasts and the decision maker's ranking of the forecasts. It is shown that ranking is effective only when the forecasts are correlated: the greater the correlation, the more effective the ranking. A sample application of this methodology to forecasting U.S. hog prices shows that ordering forecasts according to their individual performances produces a very robust and accurate combined forecast; however, this forecast is not the most accurate among the combined forecasts.

Book Description
Forecasting is required in many situations. Stocking an inventory may require forecasts of demand months in advance. Telecommunication routing requires traffic forecasts a few minutes ahead. Whatever the circumstances or time horizons involved, forecasting is an important aid in effective and efficient planning. This textbook provides a comprehensive introduction to forecasting methods and presents enough information about each method for readers to use them sensibly.

Book Description
Financial Analysts' Forecasts and Stock Recommendations reviews research related to the role of financial analysts in the allocation of resources in capital markets. The authors provide an organized look at the literature, with particular attention to important questions that remain open for further research. They focus research related to analysts' decision processes and the usefulness of their forecasts and stock recommendations. Some of the major surveys were published in the early 1990's and since then no less than 250 papers related to financial analysts have appeared in the nine major research journals that we used to launch our review of the literature. The research has evolved from descriptions of the statistical properties of analysts' forecasts to investigations of the incentives and decision processes that give rise to those properties. However, in spite of this broader focus, much of analysts' decision processes and the market's mechanism of drawing a useful consensus from the combination of individual analysts' decisions remain hidden in a black box. What do we know about the relevant valuation metrics and the mechanism by which analysts and investors translate forecasts into present equity values? What do we know about the heuristics relied upon by analysts and the market and the appropriateness of their use? Financial Analysts' Forecasts and Stock Recommendations examines these and other questions and concludes by highlighting area for future research.

Book Description
The highly prized ability to make financial plans with some certainty about the future comes from the core fields of economics. In recent years the availability of more data, analytical tools of greater precision, and ex post studies of business decisions have increased demand for information about economic forecasting. Volumes 2A and 2B, which follows Nobel laureate Clive Granger's Volume 1 (2006), concentrate on two major subjects. Volume 2A covers innovations in methodologies, specifically macroforecasting and forecasting financial variables. Volume 2B investigates commercial applications, with sections on forecasters' objectives and methodologies. Experts provide surveys of a large range of literature scattered across applied and theoretical statistics journals as well as econometrics and empirical economics journals. The Handbook of Economic Forecasting Volumes 2A and 2B provide a unique compilation of chapters giving a coherent overview of forecasting theory and applications in one place and with up-to-date accounts of all major conceptual issues. - Focuses on innovation in economic forecasting via industry applications - Presents coherent summaries of subjects in economic forecasting that stretch from methodologies to applications - Makes details about economic forecasting accessible to scholars in fields outside economics

Book Description
Range forecasts have emerged as the predominant form of management forecasts, but prior research has overlooked the information conveyed by forecast ranges. This study fills this void by examining the information content of the extent to which managers' forecast ranges overlap with the range of individual analysts' pre-existing estimates (i.e., overlap). We expect managers to signal their superior private information by issuing low-overlap forecasts. We predict and find that, compared with high-overlap forecasts, low-overlap forecasts are associated with stronger market reactions and higher accuracy of management forecasts relative to analyst estimates. Moreover, when responding to low-overlap management forecasts, analysts with prior estimates out of management forecast ranges are more likely to revise into the management forecast range, less likely to revise toward the consensus, and more likely to improve in revised forecast accuracy. Our findings suggest that investors and analysts view low-overlap management forecasts as signals of superior private information.
