As for the accuracy of the book: There’s not much quantitative data overall. The mode that Ostrom operates in is rather to show a lot of examples, then try to make some (pretty lightweight) generalizations. The last chapter introduces a model for researching coordination problems, but once again, it’s nothing quantitative, more like a set of hints about what things and relationships to look at.
All in all, the book may not be very useful to get exact numbers but it may help to generate more conceptual surface area, give more structure to the problem of coordination failures beyond the naive “tragedy of the commons” parables.
