The Persistence of abnormal returns at industry and firm levels: evidence from Spain
We apply structural equation models to longitudinal data on profits of firms within industries to study the persistence of abnormal returns. We obtain a two-way variance decomposition for abnormal returns: at firm vs. industry levels, and at permanent vs. transitory components. This decomposition enables us to assess the relative importance of the fundamental components of abnormal returns discussed in the literature. The method is applied to a panel of 5,000 Spanish firms observed over the period 1995-2000. We conclude that: (a) there are significant and permanent differences between profit rates at both industry and firm levels; (b) variation of abnormal returns at firm level is greater than at industry level; and (c) firm and industry levels do not differ significantly regarding rates of convergence of abnormal returns.Printed Journal
