摘要

我们考察了企业的政治对冲活动是否有效地缓解了政治风险。关注党派政治引发的风险,我们将政治对冲衡量为公司在共和党和民主党候选人之间的政治关系平衡的程度。我们发现,更大的政治对冲与股票回报波动性降低有关,特别是在政策不确定性较高的时期。同样,更大的政治对冲与降低崩溃风险、投资波动性和收益波动性有关。此外,收益波动性的降低似乎与公司的税收和经营活动都有关,因为我们发现,更大的政治对冲与现金有效税率波动性和税前收入波动性的降低有关。我们进一步发现,投资者能够更好地预测从事政治套期保值的公司的未来收益,这表明政治套期保值有助于改善公司的信息环境。最后,我们使用奥巴马总统的清洁能源计划进行事件研究。我们发现,在这项政策提案在国会辩论的日子里,能源和公用事业公司经历了更高的日内回报波动性(相对于其他公司和非事件日)。然而,对于能源和公用事业公司来说,这种加剧的波动性得到了缓解,因为它们在政治上受到了更多的对冲。总体而言,我们得出结论,政治套期保值是一种有效的风险管理工具,有助于降低企业风险。这篇论文被会计Suraj Srinivasan接受。

Hedging on the Hill: Does Political Hedging Reduce Firm Risk?
We examine whether firms’ political hedging activities are effective at mitigating political risk. Focusing on the risk induced by partisan politics, we measure political hedging as the degree to which firms’ political connections are balanced across Republican and Democratic candidates. We find that greater political hedging is associated with reduced stock return volatility, particularly during periods of higher policy uncertainty. Similarly, greater political hedging is associated with reduced crash risk, investment volatility, and earnings volatility. Moreover, the reduction in earnings volatility appears to relate to both a firm’s taxes and its operating activities, as we find that greater political hedging is associated with reduced cash effective tax rate volatility and pretax income volatility. We further find investors are better able to anticipate future earnings for firms that engage in political hedging, suggesting that political hedging helps improve firms’ information environments. Lastly, we perform an event study using President Obama’s Clean Power Plan. We find that on the days this policy proposal was debated in Congress, energy and utility firms experienced heightened intraday return volatility (relative to other firms and nonevent days). However, this heightened volatility is mitigated for energy and utility firms that are more politically hedged. Overall, we conclude that political hedging is an effective risk management tool that helps mitigate firm risk. This paper was accepted by Suraj Srinivasan, accounting.
