The objective of this paper is to verify if companies of economically regulated markets are discouraged to invest in research and development (R&D). Panel data analysis has been performed on a sample of 55 companies listed on the Brazilian Stock Exchange (B3), which published information on the amounts allocated to Research and Development (R&D) activities. The sample period comprises the years 2009 to 2014. Results show that regulation did not reach statistical significance in relation to the level of expenditure on R&D. However, we confirm the effects of certain characteristics of companies, such as size and performance, on R&D activities. These results may contribute to the formulation of public policies aiming at economic development. Keywords: regulation, innovation, research and development, Brazilian Stock Exchange (B3).
