Argentinean economy historiography lacks consensus as to the periodization of its recent growth phases. A related open question is the date at which Argentinean economy ended its first major growth phase. For some economists this was a consequence of the First World War, whereas for others Argentina lost positions from the Great Depression on. The aim of this paper is to contrast these views. We apply univariate analysis and unit root contrasts to the now available Argentinean GDP per capita series. The results point at 1913 as the first important break in the trend, whereas 1929 only represents a significant change in the intercept of the series. At the same time, this analysis defines three new long-term phases in the Argentinean growth process: 1875 to 1913, 1914 to 1974, and 1975 to 2000.
