摘要

随着公司和投资者的全球化,我们越来越多地面临着与全球化相关的风险评估问题。当投资者投资中国移动(China Mobile)、印孚瑟斯(Infosys)或淡水河谷(Vale)时,他们可能会获得更高的回报,但也面临额外的风险。当西门子(Siemens)和苹果(Apple)在亚洲和拉丁美洲寻求增长时,它们显然受到了这些市场经常出现的政治和经济动荡的影响。实际上,如果有的话,我们应该如何调整这种额外的风险?我们将首先概述总体国家风险、其来源和措施。我们将继续讨论主权违约风险,并研究主权评级和信用违约掉期(CDS)作为风险的衡量标准。我们将通过考察不同国家的股票风险溢价及其对估值的影响,将讨论扩展到从股票投资者的角度来看待国家风险。在第四部分中,我们认为公司的国家风险敞口不应由其注册和交易的地点决定。按照这个标准,可口可乐和雀巢都不存在国家风险。国家风险应来自公司的业务,使国家风险成为几乎每一家大型跨国公司估值的关键组成部分。在最后一节中,我们还将研究如何在估值和资本预算中跨货币移动,以及如何避免错配错误。

Country Risk: Determinants, Measures and Implications – The 2020 Edition
As companies and investors globalize, we are increasingly faced with estimation questions about the risk associated with this globalization. When investors invest in China Mobile, Infosys or Vale, they may be rewarded with higher returns, but they are also exposed to additional risk. When Siemens and Apple push for growth in Asia and Latin America, they clearly are exposed to the political and economic turmoil that often characterize these markets. In practical terms, how, if at all, should we adjust for this additional risk? We will begin the paper with an overview of overall country risk, its sources and measures. We will continue with a discussion of sovereign default risk and examine sovereign ratings and credit default swaps (CDS) as measures of that risk. We will extend that discussion to look at country risk from the perspective of equity investors, by looking at equity risk premiums for different countries and consequences for valuation. In the fourth section, we argue that a company’s exposure to country risk should not be determined by where it is incorporated and traded. By that measure, neither Coca Cola nor Nestle are exposed to country risk. Exposure to country risk should come from a company’s operations, making country risk a critical component of the valuation of almost every large multinational corporation. In the final section, we will also look at how to move across currencies in valuation and capital budgeting, and how to avoid mismatching errors.
