[3] His turn as chief economist for Argentina's largest province (home to over a third of the population) gave Ferrer national stature, though it also left him out of the halls of power after the UCRI's standard-bearer, President Arturo Frondizi, was forced to resign by conservative opponents in 1962.

Appointed a committee-member in U.S. President John F. Kennedy's Alliance for Progress, he was also invited as a founding member of the Latin American Social Science Council (CLACSO), an NGO created in 1967 in a consultative capacity to UNESCO.

His replacement, General Roberto M. Levingston, had become a supporter of the Alliance for Progress during his turn in the Frondizi administration as head of Army Intelligence and while stationed in the Argentine Embassy in Washington, DC.

Careful to placate conservatives, he appointed an "inflation hawk," Carlos Moyano Llerena, as Minister of the Economy; but, instead relied on the head of the new Ministry of Production, Aldo Ferrer, as his chief economic policy maker.

Among the results was the 2004 establishment of Enarsa, a public energy company commissioned to increase oil and gas production and to alleviate future electricity shortages such as the one Argentina suffered in April of that year.

[9] Ferrer was named editor-in-chief of Buenos Aires Económico, a local business and current affairs daily, in 2008, and in December 2010, was appointed Ambassador to France by President Cristina Kirchner.
