Almost a decade ago I was the Harvard economist that said that bitcoin was more likely to be worth $100 than 100k. What did I miss? I was far too optimistic about the US coming to its senses about sensible cryptocurrency regulation; why would policymakers want to facilitate tax…

Programming with AI is insanely fun. Process is: 1. generate code 2. read & understand code that was generated 3. make small changes "manually" (still with great autocomplete) 4. test & debug 5. make big changes with new prompt 6. go back to step 1 Pure vibe coding skips step 2…

More teasers: Title page plus an interesting result Most models of production networks are static, while I analyze dynamic flows on networks. But for worst-case/H∞ performance & robustness, only frequency zero/steady state matters. (maximum singular value of Leontief inverse)

I'll post the paper in a little bit, but here's a preview of some results on the dynamic propgation of stochastic shocks and their worst case amplfication -- which also covers model uncertainty -- over networks. I focus on production networks and information propagation.
