Harrod's dynamics and the theory of growth: the story of a mistaken attribution
指出后凯恩斯增长理论通常被认为源自哈罗德1939年的论文，但哈罗德实际试图建立经济动态学新基础，并常抱怨被误解。文章对比了哈罗德的原意与教科书解释，揭示后者过于简化，忽略了哈罗德对贸易周期的兴趣、对时滞周期理论的方法论批评，以及其非线性方法和不稳定原则的深刻含义。
Post-Keynesian growth theory is normally seen as originating from Harrod’s 1939 ‘Essay in Dynamic Theory’. Harrod, however, was trying to lay the foundations of a new approach to economic dynamics, and often complained of misinterpretation. In this paper, the grounds of Harrod’s argument are examined and compared with the ‘textbook’ interpretation. The latter is shown to be extremely reductive, as it ignores both Harrod’s interest in the trade cycle and his methodological criticism of the ‘time-lag theories of the cycle’, and it also underrates the interesting implications of his non-linear approach and the epistemic implications of the instability principle.
