An Empirical Investigation of the Campbell-Cochrane Habit Utility Model

Abstract:  This paper tests whether the Campbell and Cochrane (1999) habit utility model generates a valid stochastic discount factor for the 25 Fama-French size/book-to-market and size/momentum sorted portfolios. Campbell and Cochrane (1999) derive a consumption based habit utility asset pricing model and calibrate it to aggregate US stock market data. However, they do not test whether their model is consistent with a larger cross section of asset returns. We test their model using the methodology of Hansen and Jagannathan (1991) and Burnside (1994) . In contrast to previous studies, we find that for reasonable parameter values, the model's stochastic discount factor is inside the Hansen-Jagannathan bounds and therefore satisfies the necessary conditions for a valid stochastic discount factor. We trace the difference between our results and previous studies to the method used to estimate the model's parameters and the parameter values themselves.     

New Evidence on Risk Factors, Characteristics and the Cross-Sectional Variation of Japanese Stock Returns

This paper examines whether the cross-sectional variations in stock returns are better described by systematic risk factors or by firm characteristics such as book-to-market ratios and market capitalization. It provides new evidence from the Japanese stock market based on the recent sample period from 2002 to 2007, which is not addressed in the existing literature. Also, the new results are derived from the generalized method of moments applied to daily returns. The evidence suggests that both the firm size and book-to-market ratio are significantly related to average return premiums. There is mixed evidence, which tends to lend stronger support to the characteristic model rather than the Fama-French three-factor model as more reflective of the return dynamics in the Japanese stock market.     

The augmented Black–Litterman model: a ranking-free approach to factor-based portfolio construction and beyond

The Fama and French factor-ranking approach (1992, 1993, etc.) has been extensively applied in quantitative fund management. However, this approach suffers from hidden factor view, information inefficiency, etc. issues. Based on the Black–Litterman model (1992; as explained in Cheung 2010b Cheung, W. 2010b. The Black–Litterman model explained. J. Asset Mgmt., 11: 229–243. [Crossref] , [Google Scholar]), we develop a technique that endogenizes the ranking process and elegantly resolves these issues. This model explicitly seeks forward-looking factor views and smoothly blends them to deliver robust allocation to securities. Our numerical experiments show this is an intuitive and practical framework for factor-based portfolio construction, and beyond. This article features: (1) a new and unified framework for strategy combination, factor mimicking and security-specific bets; (2) an elegant and ranking-free approach to factor style construction; (3) worked examples based on the FTSE EUROTOP 100 universe; (4) insight into the classic issue of confidence parameter setting; and (5) implementation guidance in an appendix.     

金融发展与全要素生产率相关性分析——来自某省面板数据的经验

本文基于内生增长理论以及DEA-Malmquist指数法对2002-2008年我国南方某省各市的全要素生产率变动进行测算,并使用系统GMM动态面板对金融发展和全要素生产率变动值进行回归,在教育、外贸依存度和资本形成等要素条件一定的情况下,发现：以股票市值与贷款余额之比表示的金融结构,以贷款与存款之比表示的金融效率能够改善全要素生产率：而小银行的贷款占比却没有起到改善作用。     

An alternative three-factor model for international markets: Evidence from the European Monetary Union

In this paper, we construct the three-factor model introduced by Chen et al. (2010) for a European sample covering 10 countries from the European Monetary Union and the period from 1990 to 2006. Two key findings result. First, we show that the properties of the European factors are comparable to those of the US factors. Second, we show that the alternative three-factor model’s explanatory power is either equal or superior to the explanatory power of traditional models when applied to five commonly known stock market anomalies. Our results thus suggest the use of international versions of the Chen et al. (2010) factor model in addition to traditional factor models in international empirical finance research.     

我国银行间债券市场属性研究

银行间债券市场是传导货币政策的重要环节,2009年成为应对国际金融危机的适度宽松货币政策的重要微调传导渠道。对其属性的正确判断,直接影响到货币当局选择政策工具的准确性和分析政策效果的可靠性。理论分析表明,银行间债券市场具有资本市场属性并且不断加强,是金融体系为适应经济发展要求而进行金融功能自我强化的必然结果;实证结果表明:我国银行间债券市场属性正处于一个在保持原有货币市场属性的基础上,资本市场属性不断加强的阶段。银行间债券市场资本市场属性的增强容易造成货币流通速度不稳定,可能会削弱原有货币政策工具作用效力,影响货币政策的有效性,这将为今后货币政策的制定和实施带来新的挑战。     

Constructing Fama–French Factors from Style Indices: Evidence from the Islamic Equity Market

This study has contributed to the analysis of the Fama–French three-factor model by proving the validity of model using the newly constructed Fama–French factors from Malaysian Islamic stock market. With generalized method of moments and robustness tests, our results compliment earlier studies by comparing the results over two sub-periods, before and after the financial crises and the fall of Lehman Bros. The results of the analysis suggest that the reversal of size effects exists after periods of financial crisis. This is the first attempt to create FF factors and test the model from Islamic equity style indices.

Macro Liquidity Risk,Money Growth,and the Cross-Section of Stock Returns: The Case of Korea

According to the homogeneity of money holding purpose, we decompose the broad money M2 into an underlying and a non-underlying part and propose innovations in future non-underlying M2 growth as a proxy for macro liquidity. In both the cross-sectional regression tests and the GMM tests, we find that risk related to innovations in future non-underlying M2 growth is strongly significantly priced in Korea, after controlling for the well-known risk factors and other macroeconomic variables. Meanwhile, risk related to innovations in future aggregate or underlying M2 growth is insignificantly priced. These results indicate that non-underlying M2 growth more directly affects macro liquidity than does aggregate or underlying M2 growth.     

Generalised Sharpe Ratios and Asset Pricing in Incomplete Markets

The paper presents an incomplete market pricingmethodology generating asset pricebounds conditional on the absence of attractiveinvestment opportunities in equilibrium.The paper extends and generalises the seminal article ofCochrane and Saá-Requejowho pioneered option pricing based on the absenceof arbitrage and high Sharpe Ratios. Ourcontribution is threefold:We base the equilibrium restrictions on an arbitrary utility function, obtaining theCochrane and Saá-Requejo analysis as a special case with truncated quadratic utility. We extend the definition of Sharpe Ratio from quadratic utility to the entire family of CRRA utility functions and restate the equilibrium restrictions in terms ofGeneralised Sharpe Ratios which, unlike the standard Sharpe Ratio, provide aconsistent ranking of investment opportunities even when asset returns are highlynon-normal. Last but not least, we demonstrate that for Itô processes theCochrane and Saá-Requejo price bounds are invariant to the choice of the utilityfunction, and that in the limit they tend to a unique price determined by theminimal martingale measure.
