摘要:
It is shown that after base year revisions, different versions of the FRB Index of Industrial Production are similar in the time and frequency domains for the series as a whole. However, when measuring economic contractions, different versions yield substantial differences in the turning points, lengths, and amplitudes of cycles, which may be explained by the index number problem. These results suggest that when analyzing a particular historical period, it is best to use contemporaneously published data, if available.
