.05, *significance at 0.1 level. The panel data analysis included fixed effects, which remove the effects of time-invariant characteristics of economies. The functional form of the model for panel economy-wide data is given as follows: (5) ln ⁡ λ i = α + β ′ x i t

. Since it is well-accepted that the propensity to patent inventions differs across industries (Cohen et al. 2000 ; Levin et al. 1987 ), additional negative binomial regressions are run but this time with category fixed effects. Table 3 supports the
