By focussing on issues concerning precise relative performance of the human and experimental teams, Ross obscures the major, and a priori surprising result of our study. This is that the experimental teams were not all dominated by the human teams. Replication is the appropriate way to...

The formal practice of forecasting and planning (F&P) has risen to prominence within a few decades and now receives considerable attention from both academics and practitioners. This paper explicitly recognizes the nature of F&P as future-oriented decision making activities and, as such, their...

This paper proposes a new approach to time series forecasting based upon three premises. First, a model is selected not by how well it fits historical data but on its ability to accurately predict out-of-sample actual data. Second, a model/method is selected among several run in parallel using...

On p. 673, we stated that we had been refused permission to replicate our study using the Markstrat game (Hogarth & Makridakis [Hogarth, R. M., S. Makridakis. 1981. The value of decision making in a complex environment: an experimental approach. Management Sci. 27(1) 93--107.]) and questioned...

Are the costs of time and effort spent on analyzing decisions outweighed by benefits? This issue was examined in the context of a competitive business game where human teams were pitted against two kinds of simple-minded arbitrary decision rules: one where rules were applied consistently...

An alternative to using a single forecasting method is to average the forecasts obtained from several methods. In this paper we investigate empirically the impact of the number and choice of forecasting methods on the accuracy of simple averages. It is concluded that the forecasting accuracy...

Forecasting methods currently available assume that established patterns or relationships will not change during the post-sample forecasting phase. This, however, is not a realistic assumption for business and economic series. This paper describes a new approach to forecasting which takes into...
