The role of public loans in financing business R&D through the economic cycle.

Should governments increase their efforts in R&D public funding during recession periods? The objective of the present study is to compare the effect of public aid to business R&D on technological inputs and outputs through the economic cycle. We contribute to this literature by examining the effect of one specific instrument of direct public support: selective loans for firms' R&D projects. For the analysis, we consider Spanish firms supported through this kind of instrument for the periods 2002-2005 and 2010-2012. Our results suggest that the hypothesis of full crowding out of private R&D is rejected in both cycle periods, expansion and recession: public support has positive effects on the resources devoted to R&D activities. However, the effect of public support on some technological outputs depends on the cycle phase: firms supported by selective loans during the crisis are more likely to obtain product innovations.
