KNOWLEDGE CAPITAL AND PRODUCTIVITY IN SPANISH INDUSTRY
Abstract
This research is aimed at measuring the effects of firms’ knowledge capital stock changes in production, using the information provided by a panel of Spanish industrial firms for the period 2008-2016. In order to assess the size of these effects depending upon the type of industry, we split the sample into two broad branches of business activity: Low and Medium-low (LML), and High and Medium-high (HMH) technological firms. Estimate outcomes show that the elasticity of output with respect to knowledge capital is always positive and significant. Moreover, the highest productivity gains derived from innovation are observed in High and Medium-high technological firms.
