It is pointed out that both countries suffer from capital market inadequacies. Therefore, the impact of financing constraints on R&D spending is investigated using advanced econometric models. This study covers the period 1997-2019 for manufacturing firms in two emerging economies. A fractional probit model with a novel control function approach that accounts for heteroskedasticity, endogeneity, simultaneity and omitted variable bias was used in the present study. The results show a significant relationship between R&D expenditure and financing constraints for Brazil and Turkey. Moreover, the results suggest that internal financing encourages R&D spending that requires high initial fixed costs and has a high probability of failure for firms under financial constraints in these two emerging economies. Internal financing is a significant option for R&D spending for financially constrained firms in Turkey, while it is significant for financially unconstrained Brazilian firms in terms of internal financing. However, financial leverage has a negative effect on R&D spending for all firms in both countries. The results do not change when the different robustness tests are applied.eninfo:eu-repo/semantics/closedAccessR&D expendituresFinancing constraintsFractional probit modelEmerging marketsTurkeyBrazilControl function approachArticleQ1WOS:001103719300003Q1
