In this article, we examine firms’ dividend smoothing behavior across a wide spectrum of publicly listed-firms in the United States and combine the financial accounting conservatism with dividend smoothing based on theories to develop empirical hypotheses. Our findings show that conservatism is positively associated with dividend smoothing consistent with complementary effect from the perspective of information asymmetry. We also find that firms with smaller size, higher volatilities of earnings and stock return, fewer tangible assets or cash, higher leverage, and lower dividend payouts engage greater dividend smoothing.
