摘要翻译:
在这个小注中,我们使用Berestycki等人的结果。修正Hagan等人的著名公式。我们明确地导出了隐含波动率在到期日的扩展中正确的零阶项。新术语是从$\beta\到1$一致的。此外,数值模拟表明,它减少或消除了先前公式的已知病态。

英文摘要:
In this small note we use results derived in Berestycki et al. to correct the celebrated formulae of Hagan et al. We derive explicitly the correct zero order term in the expansion of the implied volatility in time to maturity. The new term is consistent as $\beta\to 1$. Furthermore, numerical simulations show that it reduces or eliminates known pathologies of the earlier formula.
