R&D investment are an important engine of growth and development. Yet economists have often claimed underinvestment, based on the consideration that these projects are more costly to finance, especially, due to the asymmetric information between inside and outside investors. Coherently, a recent empirical evidence has shown that firms intensively active in R&D are less leveraged and rely more heavily on internal finance. Motivated by this evidence, we study the effects of asymmetric information and financial frictions within a GE economy of Schumpeterian tradition. The model and equilibrium concept are rich enough to represent investment and innovation decisions, technology adoption/diffusion through patent licensing and, most importantly, firms' financial decisions. In this representation, R&D-intensive firms might effectively rely more on internal sources and equity than on debt financing, relative to what would happen in frictionless markets. Further, financial decisions affect aggregate investment and income dynamics.
