I don't know what you've covered or what would be appropriate to write about. I'd probably try to do a research paper that related something he discussed back to operations research. Like, for example, contrasting the complexity that is burdensome but reduces systemic risk (like regulations or operations checklists) versus complexity that is overtly rewarding but increases systemic risk (like the propensity for capitalism/securitization to create financial products that ultimately cause widespread correlation between otherwise unrelated failures).
Maybe another interesting question would be, does securitization (by itself) really increase complexity, or does it decrease total complexity? Commodities markets are a distinct 'thing' that adds a layer of abstraction to buying and selling goods. At the same time, commodities markets make it possible to deal in goods without needing to ship them or physically take possession of them, which means the actual act of trading is far simpler than without them. At the same time, then, do commodities markets increase or decrease systemic risk? It seems like both. They increase risk because by making goods trading far simpler, it becomes trivial to speculate on goods prices. This creates the possibility for speculative bubbles in commodities, which can destabilize markets that depend upon stable factor prices. However, with commodities markets if you accidentally order too much of something, or if your customer goes out of business, you always have some place to sell your excess (ideally, again, without worrying about shipping or receiving something you can't use).
I could probably write a few hundred pages just asking about the complexity/risk tradeoff in commodities markets.
