After graduating with a degree in political science from the
University of Pavia in 1953, he was a student of
Maurice Dobb and
Piero Sraffa at
Trinity College, Cambridge. He was the literary executor of Piero Sraffa, whose manuscripts, donated by Sraffa himself to the University of Cambridge, are preserved at Trinity College, Cambridge. In the 1960s Garegnani was, together with
Luigi Pasinetti, among the leading figures in the capital controversy, which saw him opposed to the positions of
Paul Samuelson and
Robert Solow. He made fundamental contributions to the revival of the theoretical approach that was characteristic of the classical economists and Marx along the lines indicated by Sraffa in Production of Commodities by means of Commodities and to the re-proposition of the Keynesian principle of effective demand. ==Works==
