Abstract
Considering the growth of the Gross Domestic Product (GDP) of the Northeast in the last years, this study aims to analyze if such growth occurred in a way to reduce the income disparities between the municipalities of this region. For this, the hypothesis of 𝛽-convergence, absolute and conditional, as well as 𝜎-convergence was tested. The results showed that for the region as a whole, the municipalities have the two types of convergence, in addition to the convergence. The conditional 𝛽-convergence proved to be poor, since the convergence velocity was greater than in absolute 𝛽-convergence, and consequently a shorter half-life, being a reduction of two and a half years. This shows that the variables used in conditional 𝛽-convergence (Firjan health and education), contribute to reduce the income disparities between the Northeastern municipalities.
