Tim Conley and Bill Dupor have a new paper
on the American Recovery and Reinvestment Act (that is, the Obama stimulus bill). Their empirical findings:
Our benchmark results suggest that the ARRA created/saved approximately 450 thousand state and local government jobs and destroyed/forestalled roughly one million private sector jobs. State and local government jobs were saved because ARRA funds were largely used to offset state revenue shortfalls and Medicaid increases rather than boost private sector employment. The majority of destroyed/forestalled jobs were in growth industries including health, education, professional and business services.
