‘Total factor productivity vs. realism’ revisited: the case of the South Korean steel industry
通过批判Truett和Truett的文章，指出其全要素生产率测量方法存在理论和实证缺陷，并基于韩国钢铁工业实际经济条件提出对‘现实性’的不同理解。
This paper presents key features of the development of the South Korean steel industry through the critical examination of an article by Truett and Truett. Despite their claim to exhibit 'realism' by use of a translog cost function, their methodology has strong affinities with the methods of measuring total factor productivity growth, which have long been known as invalid but continue to be applied not least to the experience of East Asian countries. It will be argued that the theoretical and empirical flaws involved with these methods invalidate their results and corresponding policy implications. Above all, by showing that the assumptions for their calculation do not hold in terms of the economic conditions of the industry, the paper points to a different understanding of 'realism' than that conceived by and for their study.
