Impact study on the interest rate futures market

Any announcement from the Federal Reserve has a huge impact on the interest rate markets. The press releases from the Federal Open Market Committee (FOMC) are major inputs to the market and the random intervention model is applied to interest rate futures transaction data to measure FOMC announcement impact. Missing prices during non-trading time periods are imputed iteratively during the estimation of model parameters. The study shows that the market trading on the announcement day is different from the market trading on a non-announcement for both the Eurodollar and T-Note futures market.     

Interest rate dynamics and volatility transmission in the European short term interest rate market

This paper investigates the price and volatility relationship in European short-term interest rate markets. Cointegration analysis is used to analyse the long and short run relationship and a GARCH BEKK model is estimated to analyse the volatility transmission between the markets. The stability of the long run relationship is also examined using Bai and Perron (Econometrica 66(1),47–78, 1998, J Appl Econ 18(1):1–22, 2003) structural break methodology. The results show that the relationship between the EURIBOR spot deposit rate and the EURIBOR future contract has changed significantly since 2001 and several structural breaks are present in the 13 year sample period. During periods where there is a long run relationship present the spot deposit rate generally leads the future rate in price discovery. In the short run there is bi-directional causality present between the markets. There is also significant evidence of volatility transmission from the spot market to the futures market throughout the sample period.     

基于CAPM模型对股票市场的收益与风险研究——以上海股票市场为例

文章依据资本资产定价模型,来论证上海股票市场收益与风险之间的关系。文章还选取了上证50板块中50支2014年的股票作为样本数据进行分析,运用时间序列分析和横截面最小二乘法的回归方法,来检验系统风险是否对个股具有显著影响。最终我们发现,非系统性风险对股票收益影响较大,系统性风险与投资收益率的关系并不符合CAPM模型,并论证通过建立投资组合可以达到分散非系统性风险的作用。

Monotonicity preserving regression techniques for interest rate term structure estimation: A note

Alternative methodologies are compared for measuring the term structure of interest rates via monotone approximations to the discount function. Some empirical comparisons using coupon bond data show that a simple linear methodology based on rational tension spline parametrizations turns out to yield the most efficient compromise between the conflicting goals of goodness of fit and smoothuess of the interpolaut Work supported by M.U.R.S.T. funds.     

Empirical evidence of conditional asset pricing in the Indian stock market

Studies of various alternative empirical asset pricing models have mostly concentrated on developed markets. However, despite the importance of this issue, surprisingly little is known about how different asset pricing models behave in emerging capital markets. The purpose of this paper is to determine the suitability of conditional compared to unconditional versions namely, the capital asset pricing model and the Fama-French three-factor model for the Indian stock market. The key distinction between the present empirical tests and previous tests is the application of the Kalman filter method for dynamic beta estimation in the Indian market. The findings indicate that the cross-sectional variation in expected returns is driven by mainly two firm characteristics size and book-to-market ratio.Unlike the unconditional model, the market beta is able to capture the variation of expected return in conditional model. The results imply that information has a role and investors use the prior belief and macroeconomic variables as predictive variables to determine the cost of capital. These results are supported by some recent findings that Fama-French three-factor model is the only multifactor model that consistently sources three different types of risk included in the list of anomalies.

Nonlinear mean reversion in the term structure of interest rates

The expectations hypothesis implies that the yield curve provides information on the future change in the short-term interest rate. However, transaction costs exist in the financial market, which prevent investors from realizing the arbitrage opportunity, when the arbitrage does not fully cover the transaction costs. The purpose of this paper is to assess the effect of transaction costs on the predictability of the term structure by using the threshold vector error correction model, which allows for the nonlinear adjustment to the long-run equilibrium relationship. A significant amount of threshold effect is found, and the adjustment coefficients are regime-dependent. The empirical result supports the nonlinear mean reversion in the term structure of interest rates.     

Term structure of interest rates in the Singapore Asian dollar market

This paper investigates empirically the term structure of interest rates in the Singapore Asian Dollar Market. We consider extended versions of the ARCH-M model of Engle, Lilien, and Robins (1987). The extended models permit autocorrelation, skewness and leptokurtosis in the residuals. The robustness of the empirical tests with respect to alternative specifications of the ARCH process is examined. It turns out that there is significant time-varying term premium, and this conclusion is independent of the hypothesized ARCH model.     

Monetary policy regimes and the term structure of interest rates

US monetary policy is investigated using a regime-switching no-arbitrage term structure model that relies on inflation, output, and the short interest rate as factors. The model is complemented with a set of assumptions that allow the dynamics of the private sector to be separated from monetary policy. The monetary policy regimes cannot be estimated if the yield curve is ignored during estimation. Counterfactual analysis evaluates importance of regimes in policy and shocks for the great moderation. The low-volatility regime of exogenous shocks plays an important role. Monetary policy contributes by trading off asymmetric responses of output and inflation under different regimes.
