中国股票市场流动性风险溢价研究

本文在对Fama三因素模型和LACAPM模型进行改进的基础上,实证研究了中国股票市场的流动性风险溢价、规模效应以及价值效应。实证结果发现,改进的FAMA三因素模型能够比CAPM更好地解释价值效应,但却不能解释规模效应和流动性风险溢价现象;而改进的LACAPM在解释市场异象上的有效性则明显优于其他定价模型。     

宏观经济指标对股票市场风险溢价影响的实证研究

风险溢价波动是股票市场波动的主要来源。本文选取宏观经济主要经济指标和股票市场风险溢价,并截取2008年7月以来的月度数据,建立VAR模型。研究发现,主要宏观经济指标对股票市场风险溢价具有显著的影响。     

基于中国农产品期货市场的风险溢价与预期功能研究

本文锚定农产品期货市场分散风险与价格发现功能,在先前学者研究的基础上,以基差分解为出发点,指出F-F模型估计量存在的问题,并对其进行修正,建立联立方程计量经济学模型,对农产品期货市场的风险溢价因素和预期功能因素进行检验。研究发现,中国农产品期货市场经过二十多年的飞速发展日趋成熟,绝大多数品种能够探寻风险溢价和体现预期功能。     

基于面板模型的中国国债风险溢价实证研究

该研究采用面板模型实证分析了2003年12月至2008年4月上海证券交易所债券市场国债风险溢价与利率期限结构及宏观经济变量的关系。实证结果显示,上期利率期限结构曲线越陡峭,当期国债风险溢价越高;上期通货膨胀水平越高,当期国债风险溢价越高,而再延长一期滞后期,会发现滞后第二期的通货膨胀水平与当期国债风险溢价存在显著负关系;货币供应同比增速增加时,国债风险溢价水平降低。     

上市公司短期融资券风险溢价研究

通过对12家发行短期融资券的上市公司进行研究,分析其违约距离和短期融资券风险溢价的关系,发现二者有负相关关系.违约距离比信用评级能提供更多的关于风险溢价的信息,但不能完全解释风险溢价.     

交易所国债期限风险溢价的实证研究

本文考察了上海证券交易所国债期限风险溢价的时间变化特征及决定因素。实证结果显示，债券剩余期限越长，平均风险溢价越高；通过对不同期限债券组合的风险溢价序列建立回归模型，发现长短期利差及风险溢价的前期值对中长期债券期限风险溢价的时变性具有明显的解释能力。     

并购溢价支付风险及业绩补偿模型研究

如何并购公司不考虑目标公司发展前景的不确定性和溢价产生的条件性而盲目支付溢价，就等于向过路的人群发放钞票，是难以收回的，收购公司会为此而损失部分溢价、全部溢价甚至更多，这就是溢价支付风险。     

公司债的非流动性与风险溢价——基于中国的实证研究

本文基于四种非流动性测度,考察了公司债层面和市场层面影响中国公司债非流动性的因素,讨论了公司债非流动性、权益波动率、印花税调整等因素对公司债风险溢价的影响。研究发现,在控制了信用评级和发行人权益波动率后,在截面上只有Amihud(2002)非流动性测度对公司债风险溢价有正的显著影响。此外,公司债发行人权益波动率和2008年的两次印花税调整对公司债风险溢价有正的稳健显著影响。     

Time-Varying Variance Risk Premium and the Predictability of Chinese Stock Market Return

A number of studies have shown that the variance risk premium (VRP), defined as the difference between risk-neutral and physical expected variances, has strong predictive power for the excess stock market return, and this predictability peaks at 3- to 6-month prediction horizons. However, little research presents empirical evidences for Chinese stock market due to the absence of option market. Under general equilibrium asset pricing framework, this article estimates time-varying VRP using the Chinese stock market data. We find that the estimated VRP predicts the excess Chinese stock market return, and this forecasting power is stronger at 4- and 5-month horizons, which is consistent with the findings of existing literature.     

Time Varying Market Leverage, the Market Risk Premium and the Cost of Capital

This paper shows that, when as usual the market portfolio is proxied by a share portfolio, then the conventional Ibbotson (1999) estimator of the market risk premium violates Miller–Modigliani (1958 and 1963) propositions II and III. A new estimator of the market risk premium is proposed which is free of these defects. In addition, across the range of market leverages experienced in the US in the period 1952–1997, it generates estimates of the market risk premium that differ from those generated by the Ibbotson methodology by up to 2.5 percentage points, and weighted average costs of capital for firms that differ by up to 2.6 percentage points.     

On the Foreign Exchange Risk Premium in Sticky-Price General Equilibrium Models

The properties of the foreign exchange risk premium in general equilibrium models with sticky nominal pricesare examined. In these models, risk premiums arise endogenously because monetary shocks lead to covariationof consumption and exchange rates. In some cases, the risk premiums are much larger than those produced inneoclassical general equilibrium models.

Arbitrage, Risk Premium, and Cointegration Tests of the Efficiency of Futures Markets

This article provides a new perspective on the efficiency of futures markets in a cointegration framework. Under the conventional risk premium hypothesis, if futures and spot prices are non-stationary, they must be cointegrated if futures markets are efficient. Alternatively, the cost-of-carry model implies that there should be a cointegration relationship among spot prices, futures prices and interest rates assuming all the series contain a unit root. Market efficiency further implies specific parameter restrictions under these two models. Using data on the futures markets for gold, silver, palladium and platinum, this article first establishes that interest rates, spot and futures prices are unit root non-stationary. The evidence on cointegration is somewhat mixed: the gold futures market is consistent with the cost-of-carry model, and the silver futures market satisfies the risk premium hypothesis, but the evidence for the other two markets is inconclusive.     

Modeling Foreign Exchange Risk Premium in Armenia

This paper applies stochastic discount factor methodology to modeling the foreign exchange risk premium in Armenia. We use weekly data on foreign and domestic currency deposits, which coexist in the Armenian banking system. This coexistence implies elimination of the cross-country risks and transaction costs, leaving the pure foreign exchange risk. It is shown that there exists a systematic time-varying risk premium that increases with maturity. Using two-currency affine term structure and generalized autoregressive conditional heteroskedasticity (GARCH)-in-mean models, we find that the central bank's foreign exchange market interventions and ratio-of-deposit volumes significantly affect public expectations about foreign exchange fluctuations. We also find that the foreign exchange risk premium accounts for the largest part of the interest differential. When accounting for economic and institutional differences, our results can be extended to other countries.     

Modelling the Currency Forward Risk Premium: A New Perspective

In this paper we seek to develop a new approach to the time series analysis of foreign exchange risk premia. We do so by assuming a geometric Brownian process for the spot exchange rate and expressing the no-arbitrage spot-forward price relationship under the historical probability measure. We are thereby able to obtain a stochastic differential equation system linking the spot exchange rate, the forward exchange rate and the risk premium (modelled directly as a mean-reverting diffusion process) which we estimate using Kalman filtering techniques. We are able to use observations at a range of frequencies since the framework we set up does not involve overlapping observations. The model is then applied to the French Franc/USD, DEM/USD, GBP/USD, and Japanese Yen/USD exchange rates from 1 January 1990 to 31 December 1998. For all currencies we find evidence that the forward risk premium is stationary and exhibits substantial positive time variation.     

Estimating the Equity Risk Premium Using Accounting Fundamentals

This study uses recent developments in the theoretical modelling of the links between unrecorded accounting goodwill, accounting profitability and the cost of equity, together with Capital Asset Pricing Model (CAPM) betas, to estimate the ex-ante equity risk premium in the UK. The results suggest that, over our sample period from 1968 to 1995, the premium has been in the region of 5%. Our estimate lends support to the view that the ex-ante equity risk premium is substantially less than the historical average of the excess of equity returns over the risk-free rate, and is similar to the rates applied recently by UK competition regulators.     

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.
