Abstract

We develop a directed technical change model with two sectors, tradable and non-tradable, and dynamic firms’ decisions to invest in R&D in the presence of financial constraints. The model establishes a linkage between R&D decisions, product and process innovations, future productivity, profits, and credit constraints. The model is estimated using Portuguese firms’ data of the tradable and non-tradable sectors. We find that the previous R&D investments raises the innovating probabilities, the innovating probabilities are higher in the tradable sector, and the startup costs of innovation tend to be higher than the maintenance costs. The results also show complementary between the R&D benefits and the firm’s financial strength, diminishing marginal returns to capital on innovation benefits, and high heterogeneity of the innovation costs across industries. Finally, when the firms’ financial strength and the trade-off between tradable and non-tradable goods are considered, the R&D benefits in the non-tradable sector do not compensate its cost given the higher productivity and innovation probabilities of the tradable sector. As a result, the R&D investments in the tradable sector illustrates a misallocation of financial resources.
