Assessment of the public tools used to promote R&D investment in Spanish SMEs

In this paper, we identify the potential determinants of firm R&D to understand the effectiveness of public policies. Our results suggest a considerably low impact of tax credits and public grants on the R&D investment of the Spanish manufacturing firms. Tax credits are mainly considered by large firms that use them as a reduction in the tax burden in the corporate tax, while SMEs use public grants to alleviate financial constraints. This evidence leads to discuss alternatives to the current design of the public policies analyzed. Copyright Springer Science+Business Media New York 2014
