This paper proposes a model where heterogeneous firms choose whether to undertake R&D or not. Innovative firms are more productive, have larger investment opportunities and lower own funds for necessary tangible continuation investments than non-innovating firms. As a result, they are financially constrained while standard firms are not. The efficiency of the financial sector and a country's institutional quality relating to corporate finance determine the share of R&D intensive firms and their comparative advantage in producing innovative goods.
