Goodwin in Siena: economist, social philosopher and artist
回顾古德温在锡耶纳大学的晚年生涯，重点介绍他对不规则增长周期的理论贡献、政治哲学思想的演变以及他的抽象绘画艺术。
This article describes the years of Goodwin’s ‘third life’ at the University of Siena, stressing in particular his main contributions to economic theory, the evolution in his political and philosophical ideas and his love of art. First, after a brief description of his arrival in Siena and of the background he found there, we explore some of his contributions of the period and argue that his achievements in the explanation of irregular growth cycles are remarkable and still open to further analysis and generalisation. Second, we remark that, as testified by an unpublished essay, in these years of dramatic changes such as the fall of the Berlin Wall, his social philosophical beliefs underwent a significant evolution. Finally, we conclude with a tribute to Goodwin, the abstract painter.
