Can we at least agree on an order of magnitude?
See the Cleveland Plain Dealer over the weekend: Shale gas will not create 200,000 Ohio jobs by 2015, Ohio State University says of industry. Not only that, but here is what it says about the jobs created in Pennsylvania:
"We estimate that Pennsylvania gained about 20,000 direct, indirect and induced jobs in the natural gas industry between 2004-2010, which is a far cry fewer than the over 100,000 jobs reported in industry-funded studies (and the 200,000 expected in Ohio by 2015),"Hmm... I guess if I had to start to judge which numbers are closer to reality, I would first look at what backgrounds the various authors have in regional economics and employment research.
