Motives of Stock Option Incentive Design, Ownership, and Inefficient Investment

This paper analyzes the effects of stock option incentives on inefficient investment. Specifically, based on the motive of design, we divide stock option incentives into incentive-driven and welfare-driven incentives. Our research is based on the panel data of 511 Chinese listed companies that declared stock option incentives from 2010 to 2014, including both incentive-driven and welfare-driven incentives. Our research shows that different types of stock option incentives have different effects on inefficient investment. Generally, incentive-driven stock option incentives reduce inefficient investment, whereas welfare-driven stock option incentives do not reduce inefficient investment, but increase it. However, there is a weakening effect in state-owned enterprises due to two opposite factors, numerous restrictions and more self-interested managers. Additionally, the paper provides implications that some stock options are manipulated by managers in the designing stage in order to pursue self-interests, and therefore monitoring abnormal share price movement and performance hurdles is important to safeguard the wealth of shareholders and promote effective motivation for managers
