Mapping innovative activity using microdata

Applied Economics Letters, 2009, vol. 16, issue 18, 1795-1799

Abstract: I discuss the determinants of three alternative measures of innovative output among firms of different size. Moreover, I provide an econometric procedure for testing a Tobit model (Tobin, 1958) against a two-part model. This procedure is alternative to Cragg's (1971) test and feasible for weighted survey data.
