John Van Reenen, eden izmed ekonomskih zvezdnikov (prej London School of Economics, zdaj MIT) s kolegoma (Moretti, Steinwender) v novem working paperju razkriva pomen javnih investicij v raziskovalno-razvojno dejavnost (R&R) in njihov pomen za spodbujanje inovacij v zasebnem sektorju.
Van Reenen in kolegi ugotavljajo, da vsak 1% javnih investicij v R&R letos spodbudi za skoraj 0.5% zasebnih investicij v R&R v naslednjem letu:
In both datasets, we uncover evidence of “crowding in” rather than “crowding out,” as increases in government-funded R&D for an industry or a firm result in significant increases in private sector R&D in that industry or firm. A 10% increase in government-financed R&D generates 4.3% additional privately funded R&D. An analysis of wages and employment suggests that the increase in private R&D expenditure reflects actual increases in R&D employment, not just higher labor costs. […] We also find evidence of international spillovers, as increases in government-funded R&D in a particular industry and country raise private R&D in the same industry in other countries. Finally, we find that increases in private R&D induced by increases in defense R&D result in significant productivity gains.
