Introduction - Special issue on Shackle

The papers presented in this special issue of Metroeconomica are a sequel to a workshop on \u201cShackle\u2019s Heritage in Economics: Micro and Macro Aspects\u201d held at the University of Padova in 2006. This initiative should also be viewed as a sequel to two monographic issues on Shackle published in this journal in 1959 with contributions by Akerman, Arrow, Keirstead, Lachmann and others. The relation between Shackle and Metroeconomica goes back to 1949 when the first issue of this journal, founded by the Italian economist Eraldo Fossati, came out with Shackle\u2019s article Probability and Uncertainty and continued into the 1950s with the publication of further articles that were to disseminate the views advanced in Shackle\u2019s 1949 book Expectation in Economics
