Abstract

It is well documented that losses are less persistent than profits and that stock prices anticipate the lower persistence of losses. Yet the underlying explanation for these results is unclear. One explanation lies in the abandonment option, whereby firms with losses are more likely to curtail operations (e.g., Hayn 1995). Another explanation involves timely loss recognition stemming from conservative accounting (e.g., Basu 1997). We show that curtailments are an important factor contributing to the lower persistence of losses. An implication of our results is that popular measures of conservatism, such as the measure proposed by Basu (1997), also reflect curtailments.
