AbstractBeginning in the 1990s, firms often continue to trade on the major national exchanges after Chapter 11 bankruptcy filings. For bankruptcies filed from 1993–2003, we find that the more negative the filing period price reaction, the more favorable the immediate post-filing returns, on average. This reversal is not attributable to bid-ask bounce, it holds after controlling for other factors associated with post-filing returns, and it appears more attributable to the activities of large traders than to small traders. Supplementary tests reveal that the pattern of post-filing returns differs significantly for bankruptcies filed in bull versus bear markets. Bankruptcies filed during the 1993 to 1999 bull market enjoy substantial but short-lived reversals averaging one-third of the filing period price plunge. These reversals are inconsistent with efficient assimilation of the bankruptcy information. In contrast, we find no evidence of post-filing reversals for bankruptcies filed from 2000 to 2003.

The potential effects of “time series errors” in longitudinal analysis are examined empirically. Using a common hypothesis (the relationship between ownership concentration and research and development (R&D) spending) and a panel of 183 Fortune 500 firms (I 985-l 988) several time series errors are calculated. These analyses are then contrasted with the results of a procedure protected from time series errors. Comparisons show that (I) results may depend upon how researchers define and measure longitudinal effects; (2) time series errors can have significant effects on empirical findings; and (3) the linkage between ownership concentration and R&D may not be as clear-cut as previous studies have suggested. Recommendations for how researchers should account, save, and tell their time are offered.
