The 19 papers of the Special Issue of the Journal of Business Research guest edited by Kesten Green and Scott Armstrong and devoted to evidence on the effect of simplicity versus complexity in forecasting are now available online. We have provided a Table of Contents for the Special Issue, with links to the papers. The eagle-eyed among you will notice that the ordering of our table of contents is at odds with page number order. A miss-step in the production process saw the editors' logical ordering of the papers ignored. We have used the editors' intended order in our Table of Contents, available from the Papers Page. Please tell your colleagues about this important Special Issue; one that is relevant to all forecasting researchers and practitioners.
