Good stuff. I imported and played with a regulatory dataset.<p>The results mostly confirm industry suspicions that enforcement differs the most based on what region an operator is in (poor regulatory performance operators are mostly located in the same regulatory region).<p>What was neat was how little individual manufacturer's designs mattered. But over time, it was either hugely advantageous or hugely disadvantageous to simultaneously operate multiple types of designs. Example: in 2007 it was about 5% better to simultaneously operate multiple designs, but in 2010, it was about 17% worse.<p>Also confirmed that it was much, much better (from a penalty standpoint) to find and self-disclose regulatory non-compliance rather than to let the regulator find it.<p>Awesome work guys! Will there be an ability to play with the time dimension soon?
