“…In line with the studies that analysed Brazil's economic growth (e.g. Campos et al, 2020Campos et al, , 2023, we found that institutional quality is likely to promote Brazil's real convergence; however, the Markov Regime-Switching Autoregressive approach used permitted to uncover important non-linearities overlooked by previous studies: non-significant impacts of institutional quality on Brazil's real convergence were founded in the catching-up phase for Brazil/Portugal and in the falling behind phase for Brazil/LA6. Such an evidence suggests it is critical to independently scrutinize real convergence and economic growth processes (Bernardelli et al, 2021), and to recognize that in countries paved with high levels of poverty and inequality even after establishing more democratic regimes, the constitution, stability, and appropriate reforms proposed by it to enhance convergence may be more challenging to negotiate and achieve.…”
