Note(s):

***p < 0.01; **p < 0.05; *p < 0.1. Patent outcomes are reported for the NASA SBIR proposal pool of 2002–2012. The outcome in Panels A and B is the Average Marginal Effect of the probability of patenting for the full sample (Panel A) and the firms without prior patents (Panel B). The subsample of the largest firms in Panel B is excluded for statistical reasons. Panel C reports the coefficients of an OLS regression on the number of forward patents, conditional on patenting. The treated (with Phase II award) observations are compared to untreated (not selected for Phase II award) with a Propensity Score Matching methodology. Controls include year fixed effects and fixed effects for the NASA Center receiving the proposal
