A THEORY OF INCOME AND DIVIDEND SMOOTHING BASED ON INCUMBENCY RENTS

''Income smoothing'' is the process of manipulating the time profile o f earnings or earnings reports to make the reported income stream less variable. This paper builds a theory of income smoothing based on the managers' concern about keeping their position or avoiding interferen ce, and on the idea that current performance receives more weight than past performance when one is assessing the future. When investment is added to the model, so that income reports and dividends can be set i ndependently, we find that both dividends and income reports may be sm oothed and that dividends may convey information not present in the in come report.
