Kevin Hoefman, at Eve Fanfest 2016, discussing the University of Ghent’s LAB-M research project.
EVE Fanfest 2016 - LAB-M: EVE and the Economics of War
A great presentation, that covers PLEX price phenomena, particularly externalities from Eastern Europe that drive them.
Points to keep in mind for 2018/2019 state of things,
1 US Dollar / 65.47 RF Ruble Meaning the same circumstances that made Eve Online subscription prices undesirable for those in economies outside the USD and Euro, are still in effect.
Russian Unemployment in Dec till now hovering at 4.9%, Bank of Russia keeping one week-repo rate at 7.9 interest rate, and the most significant is Russian consumer price inflation rose to 4.3 from 3.8 in one month ( no early 2019 data yet) highest since June 2017.
Also, you continue to have the U.S. driving both itself and the Russians, as leading oil produces, to over produce oil at lowering cost, yet continued interest to the development cost for doing so, i.e., having to pay for what your doing by further producing oil, increasing supply.
This will lead to more mining, trading, passive income seeking, well beyond what botting itself is responsible for, i.e., washing ISK over the Eve economy as Eastern Europe and elsewhere look to PLEX to Omega, not subscribe, hence greater demand for PLEX overall, generating higher prices as fewer on the sell side are buying PLEX with real world money to meet the demand, for the moment.
I think the video from 2016, when he gets to PLEX price modeling back then is the clearest explanation for this all, which we have seen before.
