我国外汇储备影响因素的实证研究

外汇储备应该保持一个合理规模。文章首先对影响外汇储备的主要因素进行稳定性检验，在此基础上对外汇储备与这些影响因素之间的长期关系进行协整检验，建立了它们的长期均衡方程，并根据格兰杰定理，建立了误差修正模型。     

股票市场对我国货币政策目标影响的实证分析

近年来，由于股票市场的快速发展，股票市场与货币政策的关系问题已经成为金融研究热点之一。本文以1995—2007年的季度数据为样本，基于误差修正模型，从实证的角度分析了我国股价指数与货币政策的最终目标（通货膨胀、经济增长）和中介目标（货币供应量）之间的关系。实证结果显示，股价指数与货币政策目标之间存在长期、稳定的协整关系，并进一步分析了股价指数对货币政策目标的影响程度。

基于宏观经济动因,研究经济发展水平、利率与股票价格指数对我国总体性并购活动的影响,实证检验结果表明：除利率之外,经济发展水平及股票价格均与总体性并购活动存在长期的均衡关系,并且为总体性并购活动的Granger原因;在短期内,经济发展水平波动与股票价格波动对并购活动波动均存在正向影响,而利率波动对并购活动波动存在负向影响。这说明经济发展水平与股票价格是我国并购浪潮的重要驱动因素。     

Analysis of long-run benefits from international equity diversification between Taiwan and its major European trading partners: an empirical note

This paper employs four cointegration test approaches, PO, HI, JJ and KSS, to test for pairwise long-run equilibrium relationships between Taiwan's stock price index and each of the stock price indexes of four European markets – French, German, Dutch, and British stock markets. The results from these four tests are robust and clearly consistent in suggesting that the Taiwan stock market is not pairwise cointegrated with the four European stock markets. This provides strong evidence that there exist long-run benefits for Taiwan investors diversifying in the equity markets of Taiwan's major European trading partners, France, Germany, Holland, and the UK, over the sample period considered from 6 January 1998 to 30 May 2002. These findings could be valuable to Taiwan individual investors and financial institutions holding long-run investment portfolios in the equity markets of France, Germany, Holland, and the UK.

Market efficiency in the Spanish derivatives markets: An empirical analysis

This paper analyzes Granger caUSAlity between daily prices of the Spanish stock index (Ibex 35) and its futures contract using Johansen cointegration methodology. The study differentiates between short-run and long-run caUSAlity. The empirical results prove that, in the short run, the futures price causes the spot price. However, the opposite is not true. On the other hand, long-run caUSAlity is embodied in the response of futures prices after deviations from the long-run equilibrium. These results say that during the period of study, the Spanish futures market behaved as an efficient market.     

Predicting European Union Recessions in the Euro Era: The Yield Curve as a Forecasting Tool of Economic Activity

Several studies have established the predictive power of the yield curve for the U.S. and various European countries. In this paper we use data from the European Union (EU15), from 1994:Q1 to 2008:Q3. We use the European Central Bank’s euro area yield spreads to predict European real GDP deviations from the long-run trend. We also augment the models tested with non monetary policy variables: the unemployment and a composite European stock price index. The methodology employed is a probit model of the inverse cumulative distribution function of the standard distribution using several formal forecasting and goodness of fit evaluation tests. The results show that the yield curve augmented with the composite stock index has significant forecasting power in terms of the EU15 real output.     

中国股指期货具有价格发现功能吗?

为检验中国资本市场股指期货是否具有价格发现功能,本文在对股指期货与现货指数间的理论关系进行深入阐述的基础上,分别根据所建立的向量自回归模型参数估计结果以及脉冲响应函数,分析股指期货与现货指数两者间的领先—滞后关系。基于理论分析框架进行实证检验,结果发现:中国股指期货具有价格发现功能,但现阶段这一功能并不强;当股票市场处于下跌态势时,股指期货的价格发现功能要稍强于股票市场呈现上升态势时的情形。同时,当股票市场处于下跌态势时,季月合约的价格发现功能要强于近月合约的价格发现功能,而股票市场处于上升态势时,近月合约与季月合约的价格发现功能并没有呈现出明显差异。     

出口退税、贸易盈余和外汇储备的一般均衡分析与中国的实证

本文构建了一个简单的大国开放经济一般均衡模型,从理论上探讨了外汇储备从贸易盈余时的短期均衡到贸易平衡时的长期均衡的动态变化过程,并在此基础上量化分析了降低出口退税率对长期均衡时的外汇储备的影响。研究表明,降低出口退税率在短期内对减少贸易盈余和控制外汇储备增量有一定的帮助,但长期来看则与出口产品的价格弹性密切相关,只有降低那些价格弹性较大的产品的出口退税率,才能够有效地减少长期均衡时的外汇储备,否则可能产生适得其反的效果。中国数据的实证研究支持了理论模型的结论。由于中国的出口产品总体缺乏价格弹性,因此,近年来实行的一系列出口退税政策改革在长期内使国家外汇储备出现了一定程度的增加。本文最后提出了相关的政策建议。     

Explaining House Prices in Australia: 1970–2003*

This paper aims to explain changes in real house prices in Australia from 1970 to 2003. We develop and estimate a long-run equilibrium model that shows the real long-run economic determinants of house prices and a short-run asymmetric error correction model to represent house price changes in the short run. We find that, in the long run, real house prices are determined significantly and positively by real disposable income and the consumer price index. They are also determined significantly and negatively by the unemployment rate, real mortgage rates, equity prices and the housing stock. Employing our short-run asymmetric error correction model, we find that there are significant lags in adjustment to equilibrium. When real house prices are rising at more than 2 per cent per annum, the housing market adjusts to equilibrium in approximately four quarters. When real house prices are static or falling, the adjustment process takes six quarters.     

Econometric analysis of bank lending and business cycles in South Africa

This article examines econometric relationships between bank lending and business cycle in South Africa. Two long-run economic relationships are hypothesized between total credit and the variables, namely, coincidental indicators, spread between lending and borrowing rates, money supply, stock price index, inflation and banking sector specific factors included in the model. Of these variables, only coincident indicators, changes in money supply as well as capital, and reserve are found to exert some influence on short-run total credit availability.     

Asymmetric determinants of CDS spreads: U.S. industry-level evidence through the NARDL approach

This paper investigates the presence of asymmetries in the short- and long-run relationships between the 5-year CDS index spreads at the U.S. industry level and a set of major macroeconomic and financial variables, namely the corresponding industry stock indices, the VIX index, the 5-year Treasury bond yield and the crude oil price, using the NARDL approach. The empirical results provide significant evidence of both short-run and long-run asymmetries in the linkage between ten industry CDS spreads and the potential driving factors common for all industries, confirming the importance of asymmetric nonlinearity in this context. It is also shown that the industry equity prices, the VIX, the 5-year Treasury bond rate and, to a lesser extent, the crude oil price constitute important asymmetric determinants of these U.S. industry CDS spreads. The findings of this study have relevant implications for investors, speculators, arbitrageurs and policy makers interested in credit risk at the industry level.
