The dynamics of economic growth,oil prices,stock market depth,and other macroeconomic variables: Evidence from the G-20 countries

This paper examines the linkages between economic growth, oil prices, depth in the stock market, and three other key macroeconomic indicators: real effective exchange rate, inflation rate, and real rate of interest. We employ a panel vector autoregressive model to test Granger causality for the G-20 countries over the period 1961–2012. A novel approach to this study is that we clearly demarcate the long-run and short-run relations between the economic variables. The results show a robust long-run economic relationship between economic growth, oil prices, stock market depth, real effective exchange rate, inflation rate, and real rate of interest. In the long run, real economic growth is found to respond to any deviation in the long-run equilibrium relationship that is found to exist between the different measures of stock market depth, oil prices, and the other macroeconomic variables. In the short run we find a complex network of causal relationships between the variables. While the empirical evidence of short-run causality is mixed, there is clear evidence that real economic growth responds to various measures of stock market depth, allowing for real oil price movements and changes in the real effective exchange rate, inflation rate, and real rate of interest.

The Japanese stock market and the macroeconomy: An empirical investigation

We investigate the relationship between macroeconomic variables, such as the industrial production index, interest rate and inflation rate, and the stock market, using Toda and Yamamoto (1995)'s vector autoregressions (VAR) specification. The major findings are: (1) macroeconomic variables do Granger cause the stock market variable, while reverse is not so clear. (2) The lagged stock market variable affects its current value but its impact tend to diminish in the long-run. Policy implication we draw is that the price keeping operation by the Japanese government would not work, but appropriate macroeconomic policies would benefit not only the real market but also the stock market.     

我国资产价格波动与通货膨胀关系的理论研究与实证分析

随着次贷危机引发全球性金融危机，学术界对于货币政策是否以及如何对资产价格做出反应的争议再起。本文根据协整分析技术、Granger因果检验方法和误差修正模型，利用1998—2008年中国的季度数据，对资产价格与通货膨胀之间的关系进行了实证研究。实证研究表明：第一，我国资产价格与通货膨胀之间确实存在长期的均衡关系，其中房价变动对通货膨胀的影响大于股价变动对通货膨胀的影响；第二，我国资产价格与通货膨胀之间存在着单向的因果关系，即股票价格与房价上涨是通货膨胀的原因。     

Cointegration and causality between macroeconomic variables and stock market returns

The purpose of this study is to investigate whether current economic activities in Korea can explain stock market returns by using a cointegration test and a Granger causality test from a vector error correction model. This study finds that the Korean stock market reflects macroeconomic variables on stock price indices. The cointegration test and the vector error correction model illustrate that stock price indices are cointegrated with a set of macroeconomic variables—that is, the production index, exchange rate, trade balance, and money supply—which provides a direct long-run equilibrium relation with each stock price index. However, the stock price indices are not a leading indicator for economic variables, which is inconsistent with the previous findings that the stock market rationally signals changes in real activities.     

人民币汇率与我国股价、房价的联动关系研究

近年来,我国人民币汇率形成机制、股票市场和房地产市场发生了巨大变化,人民币汇率和股价、房价之间的信息传导和波动关联备受瞩目。本文采用VAR-MGARCH-BEKK模型,分析了我国人民币汇率、股价和房价之间的联动关系。研究结果表明,从波动的溢出效应来看,人民币汇率的波动率、股票价格的增长率和房地产价格的增长率之间存在非常明显的波动溢出效应;从资产价格的水平影响来看,人民币汇率与股票价格、房地产价格等国内资产价格的水平相关性较弱,而股票价格对房地产价格的影响较明显,并就该结论提出了相关的理论解释和政策建议。     

Stock returns,inflation and interest rates in the United Kingdom

The Fisherian theory of interest asserts that a fully perceived change in inflation would be reflected in nominal interest rates and stock returns in the same direction in the long run. This paper examines the Fisherian hypothesis of asset returns using alternative techniques of linear regression, and vector error correction models to examine the nature of the relationship between stock returns and inflation in the UK. Consistent with the Fisherian hypothesis, empirical evidence in the linear regression model suggests a positive and statistically significant relationship between stock returns and inflation, which regards common stock as a good hedge against inflation. The results based on the unit root and cointegration tests indicate a long-run reliable relationship between price levels, share prices, and interest rates which could be interpreted as the long-run determinants of stock returns. The findings also suggest a bidirectional relationship between stock returns and inflation. The evidence of a significant Fisher effect is robust across model specifications.     

Home country macroeconomic factors on outward cross-border mergers and acquisitions: Evidence from the UK

In this paper, we examine the dynamic effects of key macroeconomic factors on the UK crossborder mergers and acquisitions (CBM&A) outflows over the period 1987–2008. Using a seven variable vector autoregressive/vector error correction models (VAR/VECM), the study finds that a number of home country macroeconomic variables, including GDP, broad money supply, stock prices and real effective exchange rate exert a positive and significant influence in explaining the CBM&A outflows by the UK firms. However, inflation rates and interest rates tend to have a negative impact on the volume of CBM&A. The findings support the notion that home country macroeconomic factors can create advantages to improve the outward Cross-border M&A activities.     

Causal relations among stock returns and macroeconomic variables in a small,open economy

We investigate to what extent important results on relations among stock returns and macroeconomic factors from major markets are valid in a small, open economy by utilizing the multivariate vector autoregressive (VAR) approach on Norwegian data. Unlike many previous studies, which use a different methodology on other European markets, we establish several significant links. Consistent with US and Japanese findings, real interest rate changes affect both stock returns and inflation, and the stock market responds accurately to oil price changes. On the other hand, the stock market shows a delayed response to changes in domestic real activity.     

Predicting the bear stock market: Macroeconomic variables as leading indicators

This paper investigates whether macroeconomic variables can predict recessions in the stock market, i.e., bear markets. Series such as interest rate spreads, inflation rates, money stocks, aggregate output, unemployment rates, federal funds rates, federal government debt, and nominal exchange rates are evaluated. After using parametric and nonparametric approaches to identify recession periods in the stock market, we consider both in-sample and out-of-sample tests of the variables’ predictive ability. Empirical evidence from monthly data on the Standard & Poor’s S&P 500 price index suggests that among the macroeconomic variables we have evaluated, yield curve spreads and inflation rates are the most useful predictors of recessions in the US stock market, according to both in-sample and out-of-sample forecasting performance. Moreover, comparing the bear market prediction to the stock return predictability has shown that it is easier to predict bear markets using macroeconomic variables.     

Real Stock Returns and Inflation

This paper develops the relation between the real rate of return on the stock market and changes in the price level using a multiperiod economy with production. The observed relation between real ex post stock returns and inflation is shown to be consistent with equilibrium in an economy with rational investors. The relation between expected real returns and expected inflation is shown to depend on the form of the economy's production function and on the form of investor preferences. When the production function exhibits stochastic constant returns to scale, the model explains the negative relation between expected real returns and expected inflation which has frequently been observed in empirical studies.     

纳入资产价格的我国通货膨胀指数研究

通过比较分析1998～2010年纳入房地产、股票和大宗商品等资产价格的通货膨胀指数与当前通货膨胀指数之间的异同,得到以下结论:目前通胀水平被低估,尤其是在通胀高企的时期;加入房地产、大宗商品价格的通胀指数与目前通胀指数具有高度的一致性,应将房地产价格波动纳入当前通胀指数,并部分考虑大宗商品价格指数的影响;动态因子法是构建纳入资产价格的通货膨胀测度的较好方法。     

Explanatory factors of the inflation news impact on stock returns by sector: The Spanish case

We study the short run response of daily stock prices on the Spanish market to the announcements of inflation news at an industrial level, deepening the potential explanatory factors of this response (risk-free interest rate, risk premium and growth expectations). We observe a positive and significant response of the stock returns in case of “bad news” (total inflation rate higher than expected one) in recession, and also in case of negative inflation surprises (“good news”) in non-economic recession. This behaviour is consistent with the evolution of the company dividend growth expectations, since we observe that the relationship between this theoretical component of the stock price and the unexpected inflation, to a large extent, seems to explain the observed behaviour.     

National price levels, purchasing power parity, and cointegration: a test of four high inflation economies

The time series properties of exchange rates and wholesale prices from four high inflation countries show some evidence in support of purchasing power parity. Tests for stationarity of real exchange rates and cointegration among price and exchange rate variables are presented for Argentina, Brazil, Chile, and Israel during the 1970s and 1980s. Error correction models describe the mechanism of adjustment to long-run equilibrium.     

货币政策应该关注资产价格和汇率吗?

在Rudebusch and Svensson(1999)模型中引入了房地产价格、股票价格和汇率因素,以此为基础推导出最优货币政策反应函数。该反应函数显示,中央银行既要应对产出和通货膨胀变化,还应该考虑资产价格和汇率波动。基于GMM方法的实证分析表明,该反应函数能够较好刻画过去10多年间中国中央银行的货币政策。总体而言,该反应函数可以作为中国货币政策制定和执行的参考框架,货币政策应该对资产价格和汇率波动给予一定程度的关注。     

The Relation between Stock Prices and Inflationary Expectations: The International Evidence

This paper provides empirical evidence on the relation between stock returns and inflationary expectations for nine countries over the period 1971–80. The Fisherian assumption that real returns are independent of inflationary expectations is soundly rejected for each major stock market of the world. Using interest rates as a proxy for expected inflation, our data provide consistent support for the Geske and Roll model whose basic hypothesis is that stock price movements signal (negative) revisions in inflationary expectations. Finally, a weak real interest rate effect was found for some of these countries.     

Common stock returns,real activity,money, and inflation: Some international evidence

This paper tests whether the negative relationship between real stock returns and inflation in the United States is in fact proxying for a positive relationship between stock returns and real activity variables in six major industrial countries over 1966–1979. Consistent with Fama's ‘proxy-effect’ hypothesis, we document a negative relationship between inflation and real activity and a positive one between real stock returns and real activity variables. Real activity variables dominate money growth rates and expected and unexpected inflation in explaining real stock returns. A puzzling result that still remains is the positive role of money and the negative role of expected inflation in explaining these real stock returns in all major industrial countries.     

中国股债市场长期动态相关性的影响因素研究——基于宏观不确定性和协动性视角

本文借鉴现代宏观经济学中的无套利仿射模型,基于"定价核"的定价方式,将股票市场和债券市场收益率之间的相关系数分解为其主要驱动因素--通货膨胀、真实利率和股息率的不确定性,以及三者之间的协方差。在实证部分,采用DCC-MGARCH模型计算股票市场和债券市场收益率的动态相关系数,验证中国股债相关性的时变规则;进而通过回归分析探究所选取的解释变量对中国股债相关性的贡献。结果表明,通货膨胀和股息率的不确定性以及真实利率与通货膨胀和股息率各自之间的协动性是影响这种相关性的主要因素;通胀冲击、真实利率和股息率可以解释这种相关性与长期动态的暂时背离。其中,通货膨胀和股息率的不确定性对股债相关性的影响与其他欧美主要经济体有着不同的表现,反映了中国市场的特殊性;此外,相较于中国经济市场的平稳时期,股市动荡期间各经济因素的影响会发生改变,且模型解释力会降低。     

Monetary and financial stability in the euro area: Pro-cyclicality versus trade-off

This paper investigates the nexus between monetary stability and financial stability. We examine, in the experience of EMU between 1994 and 2008, first, the response of the term structure of interest rates, share prices, exchange rates, property price inflation and the deposit–loan ratio of the banking sector (our proxies for financial stability) to changes in the consumer price level and ECB policy rate (our proxies for monetary stability); second, whether and to what extent lower inflation has caused share price stability and how ECB policy rate has reacted to inflation. Using a sign-restriction-based VAR approach, we find that there is a pro-cyclical relationship between monetary and financial stability in the long-run. With a positive inflation shock, we find on average a 2% estimated decline in share prices. This suggests that the interest rate instrument used for inflation targeting is conducive to financial stability.     

The determination and international transmission of stock market volatility

This paper extends the literature on low-frequency analysis of the causes and transmission of stock market volatility. It uses end-monthly data on stock market returns, interest rates, exchange rates, inflation, and industrial production for five countries (Britain, France, Germany, Japan, and the US) from July 1973 to December 1994. Efficient portfolios of world, European, and Japanese/US equity are first constructed, the existence of multivariate cointegrating relationships between them is demonstrated, and the transmission of conditional volatility between them is described. The transmission of conditional volatility from world equity markets and national business cycle variables to national stock markets is then modeled. Among the main findings are: first, world equity market volatility is caused mostly by volatility in Japanese/US markets and transmitted to European markets, and second, changes in the volatility of inflation are associated with changes of the opposite sign in stock market volatility in all markets where a significant effect is found to exist. To the extent that the volatility of inflation is positively related to its level, this implies that low inflation tends to be associated with high stock market volatility.
