Resumen:
his paper deals with the macroeconomic behavior of Argentina and Brazil for the period 1995.1-2018.4. It explores whether their economic fluctuations followed a similar pattern according to their duration, intensity and timing. Although some features clearly coincide, accor-ding to the findings, Argentina?s business fluctuations are sharper and longer than those of Brazil. If they are analyzed together, the highest coincidence is observed in GDP fluctuations (72% of the observations lie on the same side of the zero line). Nevertheless, as to the rest of GDP components, the coincidences drop to nearly 50%. While Argentinian GDP, private consumption and imports have a significant correlation with their Brazilian counterparts, this association is quite modest.
