摘要翻译:
在险价值(VaR)是金融机构广泛实施的一种风险度量。本文度量了VaR计算中隐含的资产价格变动之间的相关性。使用美国和英国股票指数的实证结果表明,隐含相关性不是恒定的,而是在左尾(崩溃)事件中比在右尾(繁荣)事件中更高。

英文摘要:
Value at risk (VaR) is a risk measure that has been widely implemented by financial institutions. This paper measures the correlation among asset price changes implied from VaR calculation. Empirical results using US and UK equity indexes show that implied correlation is not constant but tends to be higher for events in the left tails (crashes) than in the right tails (booms).
