An algorithm for the orthogonal decomposition of financial return data
portfolio selection mean-variance analysis principal components of risk
2012/9/14
We present an algorithm for the decomposition of periodic financial return data into orthogonal factors of expected return and “systemic”, “productive”, and “nonproductive”risk. Generally, when the nu...
Realized Wavelet Jump-GARCH model: Can wavelet decomposition of volatility improve its forecasting?
wavelet decomposition jumps volatility forecasting Realized GARCH
2012/4/28
In this paper, we propose a forecasting model for volatility based on its decomposition to several investment horizons and jumps. As a forecasting tool, we utilize Realized GARCH framework of Hansen e...

This paper investigates the hedging effectiveness of a dynamic moving window OLS hedging model, formed using wavelet decomposed time-series. The wavelet transform is applied to calculate the appropria...
Inter-industry Inequality: An Important Source of the Urban Income Gap—Regression-based Decomposition
行业垄断 收入差距 分解夏普里值
2014/1/13
基于回归方程的收入差距分解发现，1988年、1995年和2002年，行业间收入不平等对中国城镇居民收入差距的贡献越来越大，而且这主要是由一些收入迅速提高的垄断行业造成的。同时，区位、教育、所有制和职业类型以及是否有第二职业对收入差距的贡献也在提高，是否完全就业和年龄对收入差距的贡献明显下降。因此，缩小中国城镇收入差距，亟需打破劳动力市场进入壁垒和产品市场行业垄断。此外，减轻地区间的劳动力流动障碍、...
