From time to time, analytic working papers are generated to explore selected aspects of the International Futures (IFs) modeling system. Some are used to test aspects of the model, while others become foundations for larger research efforts and writing projects. Many evolve over time, so it is important to note working paper numbers and dates when using and citing the papers.
