And the rating industry, and geopolitical actors, and the World Bank, and hedge funds, etc, etc. I absolutely agree. But I'm afraid this could get into perfect being the enemy of the good territory. Unfortunately no model is going to be complete - even including these primary actors you would need to eventually model entire populations to capture macro-scale effects of the markets at play.
I don't think they need to be so perfect, however. Teasing out this sort of information ('mapping it') is not going to be a panacea that can detect all fraud. But it will probably be a useful tool to human experts who can combine knowledge from a partial map with information from other sources and a generally mature understanding of the industry.
