Funny enough I had developed a similar approach about 2 years ago to simulate with an Multi Agent System the money markets between banks. Goal was to understand what it means to be too big too fail and how to mitigate situation whereby markets become completely illiquid. I demonstrated a simple model to the ECB in Frankfurt. Regards, Christian Hi,
interesting read! Funny enough I had developed a similar approach about 2 years ago to simulate with an Multi Agent System the money markets between banks. Goal was to understand what it means to be too big too fail and how to mitigate situation whereby markets become completely illiquid.

I demonstrated a simple model to the ECB in Frankfurt.

It touched on a few things that I noticed in working on payment topologies but hadn’t quite sorted out. Most notably the vacuousness of just applying network measures to banking relations. For example, Schettler quotes Milgram who’s arguing that the small number of steps between any random human being and someone of importance (Obama, Mandela, etc.) does not mean that they are close. These ’steps’ might be very high hurdles to take. An analogue in TARGET would be that in principle we could have a complete network. In practice we don’t see this. Probably because the cost of setting up a link are prohibitive. Also, we should not be interested in scale-freeness and power laws per se but much more in the dynamics that lead to the network formation we see. In any event, quite an interesting paper.

BibTeX, .zip of PDFs, Collection in Mendeley, etc. That would be convenient — and I could arrange, if I have time on Wednesday. Have you considered putting those in other format?
