The Effects of Corporate Governance on CEO Compensation

Abstract

The purpose of this study is to find the effects of corporate governance on executive compensation using the sample of Korean manufacturing firms listed on the Korea Exchange (KRX) from 2005 to 2012. In order to do that, this study extends empirical models of Core et al. (1999), Fahlenbrach (2009), Giroud and Mueller (2011), and finds the following results. First, internal corporate governance negatively affects executive compensation, implying that a good corporate governance can prevent outrageous compensation to top executives with poor performance. On the other hand, the interactions between internal and external corporate governance mechanisms have mixed results. While the first interaction has little impact on executive compensation, the second interaction among three different mechanisms has a positive and statistically significant impact. These results imply that while internal corporate governance and product market competition works against executive compensation, labor union may be in the same boat with managers in terms of compensation. Unlike most previous studies based on one-dimensional approach, this study investigates interactions among various corporate governance mechanisms. Overall results have a few important economic and social implications. Because internal corporate governance works as an effective mechanism, policymakers should find ways to make internal control mechanisms as independent as possible.
