Hi - I was pleased to see some data - but it was quite ironic, because the economic model didn't explain its definitions, and when you followed the link to be able to check the fundamental aspects necessary to pay any attention to it, the source data and the explanations of what exactly the data covered, were behind a paywall. So for me, this economic model was uninformative and underlined a different point than the one intended. (Not a journal's paywall, but a paywall nevertheless.)
