His professional life...
Already famous for his outstanding, penetrating analyses, he led discussion groups and headed a journal; he was also commissioned to conduct studies by the Argentine Rural Society. His professional life soon gave him an insight into other realities, including those of Australia, Canada, the United States and Europe, which opened up his horizons considerably. He then began to work at the Banco de la Nación in Argentina and to edit the Revista Económica published by that entity.
Despite his training grounded in the principles of free trade and the gold standard, he underwent a radical shift in outlook following his experience at the Banco de la Nación during the crisis years and the depression of the early 1930s and now advocated strong intervention by the State as a promotor of development. The Central Bank of the Republic of Argentina, set up in 1935 was, to all intents and purposes, his personal creation and enhanced his prestige across the continent. Thanks to his work in the Government, he also gained his first experience in working towards regional integration.
Prebisch's vocation as a technocrat enabled him to act in the sphere of the State notwithstanding major changes in political leadership and forms of government, which made him the target of many criticisms. The situation became even more difficult during the Second World War, because of his pronouncements in favour of the allies and the distrust towards him at the start of the Peronist Administration due to his role in earlier conservative governments.
