Motivated by a divergent behavior of long-term sovereign bond yields across emerging market economies in the onset of the COVID-19 pandemic, we employ the Bayesian model averaging to uncover the country-specific factors that explain those differences. The most pronounced determinants of a country's vulnerability to the COVID-19 shock were: (a) low GDP dynamics and (b) high sensitivity of bond yields to VIX in the period preceding the pandemic. Our results speak to the role of growth fundamentals in building-up the exposure to crises in emerging markets. They also signify a persistent differentiation of emerging economies by international investors.
受新冠疫情爆发之初新兴市场经济体长期主权债券收益率的不同表现所驱动,我们采用贝叶斯模型平均法来揭示解释这些差异的特定国家因素。一个国家易受新冠疫情冲击的最显著决定因素是:(a)低GDP动态变化,以及(b)疫情爆发前时期债券收益率对恐慌指数(VIX)的高敏感性。我们的研究结果表明增长基本面在新兴市场危机风险积累中的作用。它们还表明国际投资者对新兴经济体的持续分化。
