Do equity incentives for the managements have impact on stock-pricing efficiency? Evidence from China

Abstract

Purpose

The purpose of this paper is to investigate the impacts of equity incentive on stock pricing efficiency, as well as the institutional investors’ response to equity incentive and its role in stock pricing efficiency.

Design/methodology/approach

Using a sample of 1,842 companies that announce implementing equity incentive schemes during the period 2009-2018, the authors compare the pricing efficiency between the firms with equity incentive and those without equity incentive, and companies that implement equity incentive before and after the implementation of equity incentive by using multiple regression and propensity score matching -DID (difference in difference) method. In addition, the multiple regression model is built to test the response of institutional investors to equity incentive and its role in the efficiency of stock pricing.

Findings

The empirical results indicate that a company’s stock price is influenced more by firm-specific information than systematic factors after it announces a stock-based compensation scheme. Institutional investors respond positively to companies that implement equity incentives. Among the companies that have implement equity incentive, the higher the shareholding ratio of institutional investors, the higher the efficiency of stock pricing.

Originality/value

The authors innovatively establish a connection between the implementation of equity incentive and the operation of stock market. The results imply that besides alleviating the agency problem, equity incentives can also improve the efficiency of stock pricing, which provide empirical evidence to support the positive effect of equity incentive.
