Nonlinearity between CEO power and firm leverage: evidence from the threshold model

This paper examines the non-linearity between Chief Executive Officer (CEO) power and firm leverage using a sample of 295 selected small and medium-sized enterprises listed on China Shenzhen Stock Exchange SMEs Board during the period 2009–2013. Specifically, a threshold estimation technique developed by Hansen (J Econ 93(2):345–368, 1999) is applied to investigate whether firms with powerful CEO use a sub-optimal leverage. The results confirm that there is a double-threshold effect exist and suggest an inverted U-shaped relationship between CEO power and firm book value-based leverage. Thus, these findings reveal that the distribution of decision-making power within firms can affect financing decision are made and CEOs with higher ability to exercise decision-making power tend to use lower leverage to pursue their own benefits.
