Caffè was particularly interested in economic policy and welfare, especially in their social dimensions. One of his books, Lezioni di politica economica (Lectures on Economic Policy), is widely regarded as the complete summary of his ideas. He was a strong critic of free trade, avowedly Keynesian in inspiration, and also very interested in the Scandinavian welfare model.See Nicola Acocella and Mario Tiberi, Caffè: the man, the teaching, and the intellectual path, World Economic Forum Association Newsletter, 4(1), February 2014.
