Fildes, Hibon, Makridakis and Meade (1998), which will be referred to as FHMM, extends two important published papers. The idea of taking findings from each study and testing them against the data used in the other study is a good one. Such replications and extensions are important in the effort...

Based on a summary of prior literature, I conclude that tests of statistical significance harm scientific progress. Efforts to find exceptions to this conclusion have, to date, turned up none. Even when done correctly, significance tests are dangerous. I show that summaries of scientific...

Competitor-oriented objectives, such as market-share targets, are promoted by academics and are commonly used by firms. A 1996 review of the evidence, summarized in this paper, found that competitor-oriented objectives reduced profitability. We describe new evidence from 12 studies, one of which...

The commentaries reinforce my belief that research evidence alone is not sufficient for organizations to consider new methods. I suggest procedures to facilitate the implementation of evidence-based findings

The Neyman-Pearson theory of hypothesis testing, with the Type I error rate, plusmn;, as the significance level, is widely regarded as statistical testing orthodoxy. Fisher's model of significance testing, where the evidential p value denotes the level of significance, nevertheless dominates...

Kesten Green and J. Scott Armstrong answer this question by describing experiments they conducted, asking experts as well as university students to make predictions based on some similar situations, using structured analogies and simulated interaction. They were amazed by some of the results

Using findings from empirically-based comparisons, Scott Armstrong develops nine generalizations that can improve forecast accuracy. He finds that these are often ignored by organizations, so that attention to them offers substantial opportunities for gain. In this paper, Scott offers...

Corporate Strategic Planning (CSP) reports on an important study of planning practices and the value of those practices. Though it is a long book, nearly 500 pages, one can get almost the full benefit by reading about 200 pages. In fact, CSP contains an excellent summary (Chapter 11) that is...

Subjects (n = 1015) working individually in the role of managers were asked to choose between investment opportunities that would either double their investment or cause the loss of half of it. Six administrators ran experiments on 27 occasions in six countries over a five-year period....
