Why energy projects like Keystone XL overstate job creation

A pair of economists from Ohio State University issued a report that says the likely number of jobs that a burgeoning shale gas industry could create in Ohio has been grossly overstated – by a factor of 10 – by industry proponents and politicians who are trying to fast-track its development.
The statement is important because it debunks economic development estimates not only for this industry in this state, but potentially for any politicized energy project (think TransCanada’s Keystone XL pipeline to bring energy from Alberta’s oil sands to the U.S.) being promoted on the promise of job growth.
