This study examines the impact of growth prospects, leverage and firm's size on dividend behavior in Taiwan's firms. I carry out 4116 firm-year study by empirically analyzing the determinants of dividend policy on a sample of 686 quoted firms in Taiwan over the testing period from 2005 to 2010. I use the testing period and more refined dividend measures than previous studies. I also introduce dummy variables to capture economic policy changes.Dividend behavior is tested by using Lintner (1956) model and its variants on the pooled cross sectional/time series data for observations from 2005-2010. The models are estimated using the ordinary least square (OLS) method. The result shows that there is significant interaction between the conventional Lintner model and dividend decisions of Taiwan's firms. Drawing from traditionally financial theories, Jensen (1986) and Chariot and Vafeas (1998), I hypothesize that the relationship between the traditional determinants and dividend behavior in Taiwan's firms which depends on growth prospects, lever of gearing and firm's size. I partition the data into three classes which each based on growth opportunities, lever of gearing and firm's size.The empirical results reveal that dividend policies of Taiwan's firms are influenced by earnings, economic policy changes, growth potentials and long-term debt. However, the validity of Lintner model and its variants on dividend policy in Taiwan's firms which is somehow remote, partly depends on the growth prospect, lever of gearing and firm's size.
