The role of director incentives in investment efficiency

Abstract

Purpose The existing literature involving director compensation has been concentrating on its absolute or intrinsic values. Although the relevant studies have generated mixed findings, research in other fields suggests that the power of an incentive may be determined by its value relative to the chosen referencing standard more than its absolute value. This study aims to investigate how relative director pay affects corporate investment efficiency. Design/methodology/approach This study takes a fresh theoretical viewpoint by framing the investigation using the dimensional comparison theory and proposing that a directorship also presents a relative value that may influence the board’s performance. Ordinary least squared regressions and two-stage system generalised method of moments are used to analyse 14,267 firm-year observations. Findings The empirical results suggest that the relative director pay is a better estimate of the power of the incentive than the absolute pay. A positive association between the relative director pay and investment efficiency is evident, while the absolute pay has no significant effect on investment decisions. Director overcompensation, however, will cancel out the positive effect of director compensation on investment efficiency. Firms with relatively lower unexpected investment (UI) level benefit the most from an increase in the relative director pay, while neither absolute nor relative director pay affects investment choices in firms with a high UI level because of significantly more overcompensation. Originality/value To the best of the authors’ knowledge, this study is the first attempt to investigate the effect of relative director pay. It is also the first to examine the role of dimensional comparison in strategic decisions which is the single untended comparison framework in the director pay design. The current director pay structure has emphasised social and temporal equality by standardising the pay structure and vesting the equity-based pay over a long period. Yet it ignores the fact that people decide their commitment level by comparing the reward with an internal referent too. The findings speak to the dimensional comparison theory in that the inequality emanated from dimensional or internal comparison may be accentuated by the perceived equality in other comparison frameworks, driving the different performances in the roles one assumes.
