He received his first master's degree in a two-year international study program organised by the University of Chicago, receiving the second jointly with his PhD from the University of California, Berkeley.

He then switched to the Inter-American Development Bank (IDB), where he stayed for a number of years. He held a range of positions at the IDB, from economist in charge of analysing social projects to adviser to the executive vice-president. For his last six years in Washington he was in charge of the office of the Presidency of the bank and a member of the board of executive directors of the bank. From September 1994 he was IDB representative for Europe in Paris.
