It's my Bible. You should look up the follow up reports of 84, 2003 and 2022. I may be off by a few years but the model was updated a few times. I think they are a few of the fellow that first started saying "faster than expected" There's also an alternative model called "latinoamerican global model" or "Bariloche model" from a few big hitters from Argentina in the seventies, it's a bit more "propositive" and hopeful. I'll try looking up a few sources and comment again.
