摘要
本文从两个方面展开对高管股票期权的研究。首先,我们对Johnson和Tian (Journal of Financial Economics, 57 (2000b))的单指数高管股票期权进行了推广,以纳入多个共同风险。其次,我们使用预期效用框架来分析传统和指数期权授予对风险厌恶型高管的效率和激励效应。如果企业授予相同数量的每种期权,并调整其货币量以为高管提供相同的效用,那么单指数和多指数期权授予比传统期权更便宜,同时提供更强的股票价格上涨激励。如果公司调整授予期权的数量,而不是调整他们的资金,以产生相等的效用,指数期权授予比传统的授予更昂贵。对于面临多重共同风险的企业来说,多指数期权比单指数期权成本更低,对股价的激励作用更强。
RISK-AVERSE EXECUTIVES, MULTIPLE COMMON RISKS, AND THE EFFICIENCY AND INCENTIVES OF INDEXED EXECUTIVE STOCK OPTIONS
We extend research on executive stock options in two ways. First, we generalize Johnson and Tian's (Journal of Financial Economics, 57 (2000b)) single indexed executive stock option to incorporate multiple common risks. Second, we use an expected utility framework to analyze the efficiency and incentive effects of traditional and indexed option grants for risk-averse executives. If firms grant equal numbers of each option type and adjust their moneyness to provide equal utility to executives, single and multi-indexed option grants are less expensive than traditional options while providing stronger incentives to increase stock price. If firms adjust the number of options granted instead of their moneyness to produce equal utility, indexed option grants are more expensive than traditional grants. For firms facing multiple common risks, multi-indexed options are less expensive and provide stronger incentives to increase stock price than single indexed options.
