William of Occam wrote, "It is vain to do with more what can be done with fewer". A call for papers from the Journal of Business Research asks, what is the right level of complexity for forecasting methods and how does it vary with the conditions? Researchers are invited to send proposals for experimental studies examining multiple reasonable hypotheses, replications and extensions of important studies, and meta-analyses of evidence on simple versus complex forecasting methods and the effect of conditions on forecast accuracy for this Special Issue of the Journal of Business Research. The deadline for detailed proposals is 30 November, 2012, and the CFP is available here.
