In a recent study titled Does NIH select the right healthcare ventures through the SBIR grant program?, researchers from Rutgers University and the University of Connecticut took advantage of the 2009 American Recovery and Reinvestment Act (ARRA) to conduct a natural experiment. The opportunity was available due to the National Institutes of Health (NIH) decision to use ARRA dollars to fund additional Phase I SBIR awards from general SBIR competitions, and the researchers compared these 19 ARRA-funded awards to the other 479 Phase I awards that were first funded in the same competitions with regular appropriations.
