Barreiras não tarifárias no comércio internacional: Estudo bibliométrico em periódicos científicos entre 1966 e 2018
Brasília: Instituto de Pesquisa Econômica Aplicada (IPEA)
Although non-tariff barriers (NTBs) are one of the main barriers to trade nowadays, Brazil seems to lack a research program that investigates their effects. This study aimed to conduct a bibliometric analysis of scientific articles evaluating NTBs in the scope of international trade, being the previous step for an analytical study of theories and methodologies adopted within the theme. The research strategy combined bibliographic survey techniques, content analysis to select articles and quantitative evaluation to measure variables of interest. The analysis was done using the 3 basic laws of bibliometrics: Lotka, Bradford and Zipf. The selection strategy collected a sample of 425 scientific articles published between 1966 and 2018, signed by 358 first authors and 299 co-authors, who are affiliated with 306 institutions based in 62 countries. The results presented highlight the main researchers on the subject, the universities and institutions that host these researches and in which countries they are based, the academic journals that publish the most regarding the theme and the most frequently used keywords. Thus, this work presents the profile of the scientific production dedicated to study non-tariff barriers and strengthens the hypothesis that production is still incipient at international level and almost non-existent in Brazil.
