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.
