Executive stock options: volatility, managerial decisions and agency costs

Abstract

This paper proposes a new rationale for understanding managerial contracts which set-out to induce stock price volatility in the form of granting of executive stock options. First, we suggest that previous research focuses too much on short term volatility effects and offering neither a theoretical or empirical perspective on incentives which might influence long-term behaviour. To address this, we offer a theoretical structure of why managerial incentives might be important in determining the evolution of volatility over the life of an option contract and provide empirical support for our views. Second, we examine the impact of option moneyness on managerial behaviour over time and provide an analysis, with supporting empirical work, of the unintended incentives thereby created. Our approach suggests that volatility-inducing contracts do not work in the intended manner and supports a growing body of work which indicates that option-based remuneration does not incentivise managers to enhance corporate performance. Our evidence is within a UK context, based on a near-population sample size.
