本文研究了发达国家和新兴国际市场中不同的beta估计方法。对于所有市场来说,基于每日数据的估值机构都要优于基于月度数据的估值机构。令人惊讶的是,最佳的窗口长度是相同的,发达市场大约为12个月,而新兴市场则更长一些。最好的估计方法包括双重收缩、长记忆(FI)和简单的组合方法。FI模型对发达市场和新兴市场的预测通常都是最好的。对于投资组合的形成,双重收缩、FI和组合估计也表现最好。
This paper examines different beta estimation methodologies for a large set of Developed and Emerging international markets. For all markets, estimators based on daily data outperform those based on monthly data. The optimal window length is surprisingly homogeneous, at roughly 12 months for Developed Markets, while tending to be somewhat longer for Emerging Markets. The best estimators include a double-shrinkage, a long memory (FI), and a simple combination approach. The FI model generally yields the best predictions for both Developed and Emerging Markets. For portfolio formation, the double-shrinkage, FI, and combination estimators also perform best.
