Abstract
Fudenberg and Tirole (1995) argue that concern about job security creates an incentive for managers to smooth earnings. Consistent with their model, Defond and Park (1997) show that managers smooth earnings in consideration of both current and future relative performance. To provide a more direct evidence of anticipating smoothing and job security, we hypothesize that the extent of income smoothing will vary with managers' job security concerns as proxied by the level of the investment opportunity set or growth opportunities. Our results confirmed our predictions.
