3、ke a closer look at the impact of monetary policy on stock returns by utilising thirty years of data across thirteen OECD countries. Given the considerable debate on the relative merits of money aggregates during the late 1970s and early 1980s, we adopt the nowadays standard approach of measuring mo

We expand previous work by examining the sensitivity of our findings to the inclusion of dividend payments in the stock returns calculation, while considering both nominal and real returns. Our results indicate that for the majority of the countries under

We also examine the contemporaneous effect of monetary policy on stock returns taking into account the non-normality typically inherent in such data as well as the significant co-movement of internatio

The implications of such findings for monetary policy making and investor portfolio formation are highly important.Central bankers and stock market particip

Monetary authorities in particular face the dilemma of whether to react to stock price movements, above and beyond the standard response to inflat

On the one hand, the proactive view advocates that monetary policymakers should alter interest rates in response to developing stock price bubbles in order to

9、reduce overall macroeconomic volatility . On the other hand, according to the reactive approach, monetary authorities should wait and see whether the stock price reversal occurs, and if it does, to react accordingly to the extent that there are implications for inflation and output stability. Hence,

10、 the reactive approach is consistent with an accommodative expost response to stock price changes . Despite the difference in the timing of the reaction, both approaches effectively assume that the monetary authorities can affect stock market value. It is apparent then, that the empirical verificati

The next section discusses the theoretical framework underlying the relationship between monetary policy and the stock market. The present value or discounted cash flow model offers use

Thorbecke (1997) employs a number of alternative methodologies to examine the relationship between monetary policy and stock pr

Using a VAR system that includes monthly equity returns, output growth, inflation, and the federal funds rate, he finds that monetary policy shocks, measured by orthogonalized innovations in the federal funds rate, have a greater impact on smaller capitalisation stocks, th

In the same paper, Thorbecke (1997) adopts the Boschen and Mills (1995) index as an alternative measure of monetary policy conditions. In line with his VAR estimates, he finds that

15、 expansionary monetary policy exerts a large and statistically significant positive effect on monthly stock returns. In a recent study, Cassola and Morana (2004) also employ the VAR methodology. In particular, they use a cointegrated VAR system including real GDP, inflation, real M3 balances, short

Their results from impulse response analysis indicate that a permanent positive monetary shock has a temporary positive effect on real stock prices. Patelis (1997

Following Fama and French8 (1989), he employs the long-horizon regression methodology, using two sets of explanatory variables: monetary policy variabl

They sho

Their motivation for the employment of the discount rate as a proxy for the stance of monetary policy follows from the view that the discount rate is typically regarde

This argument is based on Wauds (1970) suggestion that discount rate changes affect market participants expectations about monetary policy. Since rate changes are made only at substantial intervals, they represent a somewhat discontinuous

Financial economists discuss various reasons why changes in the discount rate may affect stock returns. For example, discrete policy rate changes infl

In a subsequent study, Jensen, Mercer and Johnson (1996) extend the Fama and French (1989) analysis by suggesti

The results also indicate an asymmetry in the relation between business conditions and stock returns: business conditions could predict future stock returns only in periods of expansive monetary policy. Conover, Jensen and J

They find that stock returns in twelve OECD countries over the period 1956-1995 are generally higher in expansive US and local monetary environments than they are in re

28、十三经合组织国家三十年的数据，近距离观察的影响货币政策对股票的回报。讨论了可观的钱相对的价值在70年代晚期和80年代早期,我们采用了标准的方法测量现在货币政策变量使用利率。我们把以前的工作通过检查的敏感性,我们的研究,包括股利发放股票收益的计算,在考虑两个名词词组和真正的回报。我们的研究结果表明,大多数的国家接受调查的货币环境对投资者要求的回报是一个重要的决定因素 。同时我们还会检测效果的货币政策对股票收益的非常态性通常考虑自身的重要数据,以及同步性国际股票市场。其主要的结果,扩张性的货币政策推动了股市,但仍存在在大多数样本国家在很大程度上的背道而驰。这样的结果的对货币政策制定和投资者的投资组

29、合是有非常重要意义的。中央银行家和股票市场参赛者还是应该充分认识到货币政策和股市表现之间关系,以更好地了解政策变化的影响。货币当局面临着困境,特别是是否对股票价格的变动,超越标准响应的通货膨胀和输出的发展。有一种持续争论的货币政策规则之间的“先发制人式”的文学及无功补偿的方法。另一方面,“先发制人式”观点的基调,货币政策制定者应该改变利率以应对发展中股价泡沫,以降低整体宏观经济波动。另一方面,根据无功的方法,货币当局应该等待,看看是否在股票价格逆转发生了,而如果是,这在一定程度上反应有意义的通货膨胀和输出的稳定性。因此,无功的方法是一致的,与一个宽松的开放的股票价格的变化反应。尽管是不同反应时
