Exploring the Physical Properties of Regulatory Ecosystems – Professors Daniel Martin Katz + Michael J Bommarito

The rate at which US Companies cite regulations as an obstacle has quadrupled over the last 20 years (via Quartz)

“Michael Bommarito II and Daniel Martin Katz, legal scholars at the Illinois Institute of Technology, have tried to measure the growth of regulation by analyzing more than 160,000 corporate annual reports, or 10-K filings, at the US Securities and Exchange Commission. In a pre-print paper released Dec. 29, the authors find that the average number of regulatory references in any one filing increased from fewer than eight in 1995 to almost 32 in 2016. The average number of different laws cited in each filing more than doubled over the same period.”

Starting with the original Milgram research in the 1960’s to the Dodds, Muhamad & Watts (2003) paper in Science, the exploration of the social distance between individuals in society has been a topic of interest to many scientists.  This new release from researchers at Facebook highlights that social distance is indeed declining.  For those who might be interested – I detail in these slides and these slides the history of the small world research.
