There is limited evidence on the role of participating in international trade in the diffusion of technologies. This paper analyzes the impact of exporting on firms' adoption of more sophisticated technologies, using a novel dataset, the Firm-level Adoption of Technology survey, which includes more than 1,500 firms in Brazil. The survey provides detailed information on the use of more than 300 technologies, combined with data from Brazil's census of formal workers and export data from the Ministry of Trade. To address critical endogeneity concerns, the analysis applies difference-in-differences with multiple periods to examine the effects of entering export markets on technology adoption. The findings show that exporting has a positive effect on firms' likelihood of adopting advanced technologies in business functions related to business administration, production planning, supply chain management, and quality control, which are important for managing tasks associated with export activities.
