实际股票收益率与通货膨胀率关系的实证研究

股票收益率与通货膨胀率之间的关系至今仍无定论.采用1991年1月到2011年8月的月度数据,运用VAR模型对我国的股票收益率与通货膨胀率之间的关系进行实证分析,结果发现不论是预期的通货膨胀还是非预期的通货膨胀与股票实际收益率都是负相关关系.表明费雪效应在我国不成立,股票并不是对冲通货膨胀风险的理想工具.     

The Impact of Inflation Measures on the Real Returns and Risk of U.S. Stocks

Using different inflation measures produces economically significant differences in both the inflation record and inflation‐adjusted stock returns. We introduce a more consistent measure of the monthly Consumer Price Index (CPI) inflation rate to better measure real returns over 1913–2004, for which the official CPI exists. We also extend the series backward to 1871 on a monthly basis, an important addition to the data series. We analyze the impact of inflation on the real standard deviation of stock returns and find that, in contrast to the results for geometric mean returns, inflation adjustments have little impact on estimates of return variability.     

Stock Market Returns and Inflation: Evidence from Other Countries

This paper investigates the relation between common stock returns and inflation in twenty-six countries for the postwar period. Our results do not support the Fisher Hypothesis, which states that real rates of return on common stocks and expected inflation rates are independent and that nominal stock returns vary in one-to-one correspondence with expected inflation. There is a consistent lack of positive relation between stock returns and inflation in most of the countries.     

Stock returns and expected inflation: evidence from an asymmetric test specification

Previous studies that examined the relationship between stock returns and inflation have used a symmetric test specification, and have reported evidence of an inverse relation. We use an asymmetric model to re-examine this fundamental relationship between stock returns and inflation. We partition the study period into sub-samples of high and low inflation regimes. An inverse relation between stock returns and inflation forecasts is found during only low inflation periods, while a positive relation is detected through high inflation periods. In combination, results from both high and low inflation regimes suggest that stocks have delivered favorable inflation protection.      

Stock returns and inflation in Greece: A Markov switching approach

The paper studies the dynamic relationship between real stock returns and expected and unexpected inflation utilizing a Markov Switching vector autoregressive model (MS-VAR). The MS-VAR model has the advantage that it is able to capture the dependence structure of the series both in terms of mean and variance. Univariate and multivariate innovation decompositions are employed to separate inflation into two components, the expected and unexpected. The empirical evidence suggests that real stock returns are not related to expected and unexpected inflation and this result is independent of the method used to separate inflation into the two components. Rather, the results suggest that stock market movements are regime dependent, implying that stock market performance is not predictable.     

The Inflation Hedging Characteristics of US and UK Investments: A Multi-Factor Error Correction Approach

Historic analysis of the inflation hedging properties of stocks has produced anomalous results, with stocks often appearing to offer a perverse hedge. This has been attributed to the impact of real and monetary shocks to the economy, which influence both inflation and asset returns. It has been argued that real estate should provide a better hedge: however, empirical results have been mixed. This paper explores the relationship between commercial real estate returns and economic, fiscal and monetary factors and inflation for US and UK markets. Comparative analysis of general equity and small capitalization stock returns is carried out with inflation divided into expected and unexpected components. The analyses are undertaken using an error correction approach. In the long run, once real and monetary variables are included, asset returns are positively linked to anticipated inflation but not to inflation shocks. Adjustment processes are, however, gradual and not within period. Real estate returns, particularly private market returns, exhibit characteristics that differ from those of stocks.

Inflation illusion and the dividend yield: evidence from the UK

We report evidence that the UK dividend yield and expected inflation are positively correlated from 1962 to 1997, but negatively correlated subsequently. Using a commonly used VAR (vector auto-regression)-based procedure we find strong evidence that the positive correlation is caused both by inflation illusion and the effect of inflation on required rates of return. We also find some evidence that it is caused by inflation rationally reducing expected real dividend growth. We find that Chen and Zhao's (2009. “Return Decomposition.” Review of Financial Studies 22 (12): 5213–5249) criticism of the VAR-based procedure has little empirical relevance but that the procedure can be highly sensitive to the choice of data period.     

A VARMA Analysis of the Causal Relations Among Stock Returns,Real Output,and Nominal Interest Rates

Previous research has documented a negative relation between common stock returns and inflation. Recently, Fama 3 and Geske and Roll 6 have argued that this relation results from a more fundamental one between real activity and expected inflation. Stock returns, they argue, signal changes in real activity, which in turn affect expected inflation. However, unlike Fama, Geske and Roll argue that changes in real activity result in changes in money supply growth, which in turn affect expected inflation. Empirical tests have analyzed separately each link in the proposed causal chain. In this article, we investigate simultaneously the relations among stock returns, real activity, inflation, and money supply changes using a vector autoregressive moving average (VARMA) model. Our empirical results strongly support Geske and Roll's reversed causality model.     

Asset Pricing and Expected Inflation

This paper provides an equilibrium model in which expected real returns on common stocks are negatively related to expected inflation and money growth. It is shown that the fall in real wealth associated with an increase in expected inflation decreases the real rate of interest and the expected real rate of return of the market portfolio. The expected real rate of return of the market portfolio falls less, for a given increase in expected inflation, when the increase in expected inflation is caused by an increase in money growth rather than by a worsening of the investment opportunity set. The model has empirical implications for the effect of a change in expected inflation on the cross-sectional distribution of asset returns and can help to understand why assets whose return covaries positively with expected inflation may have lower expected returns. The model also agrees with explanations advanced by Fama [5] and Geske and Roll [10] for the negative relation between stock returns and inflation.     

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.     

COMMON STOCK RETURNS,EXPECTED INFLATION,AND THE RATIONAL EXPECTATIONS HYPOTHESIS

This paper provides empirical evidence that expected inflation has a cross-sectional impact on common stock returns. The study differs from others in that (a) the relation between stock returns and expected inflation is investigated in a two-factor asset pricing model, where the factors are the return on an equally weighted stock portfolio and the expected rate of inflation; (b) the estimation of the expected rate of inflation is based on the rational expectations hypothesis of Muth; and (c) a non-linear seemingly unrelated regression technique is employed to determine consistent and asymptotically efficient estimates. The joint hypothesis of the two-factor asset pricing model and rational expectations is not rejected in this study. It is found that the return on common stocks is significantly affected by expected inflation. Also stocks whose returns are positively correlated with expected inflation have lower expected returns.     

Are common stocks a good hedge against inflation? Evidence from the Pacific-rim countries

We explore whether the observed real stock return–inflation relations in the U.S. and 10 Pacific-rim countries for the sample period of 1970–1997 can be explained by the interaction between real and monetary disturbances. Ten countries exhibit a negative relation between real stock returns and inflation. Malaysia is the only country that exhibits a positive relation. For nine countries, real output disturbances drive a negative stock return–inflation relation, while monetary disturbances yield a positive relation. In addition, real shock components appear to be relatively more important than monetary shock components for these countries, and as a result the observed relation between stock returns and inflation is negative. Neither the tax hypothesis nor the monetary regime hypothesis seems to be easily compatible with the diverse experiences of the Pacific-rim countries.     

Capital Gains, Dividend Yields, and Expected Inflation

One explanation for the negative relationship between short-horizon stock returns and inflation is that inflation proxies (inversely) for expected future real output. In this paper, I examine the possibility that inflation also proxies for variation in real price/dividend ratios (excess returns). I show that when the covariance between real price/dividend ratios and inflation is nonzero, the relationship between returns and expected inflation differs for the two components of returns: dividend yields and capital gains returns. My empirical evidence demonstrates that dividend yields and capital gains are related differently to expected inflation in U.S. and foreign markets.     

Public Information Arrival and the Fisher Effect in Emerging Markets: Evidence from Stock and Bond Markets in Turkey

We examine the impact of inflation on nominal stock returns and interest rates in Turkey's emerging economy, which has a moderately high, persistent, and volatile inflation rate. Empirical evidence indicates that Turkey's inflation increased more than nominal stock returns and interest rates, implying that real returns to investors declined during our sample period. Among the different sector indexes we study, the financials sector serves as the best hedge against expected inflation, and the Fisher effect appears to hold only for this sector. We also find that public information arrival plays an important role, especially in the stock market.     

Stock Prices and Inflation: New Evidence from the Pacific-Basin Countries

This paper investigates the statistical relationship between stock prices and inflation in nine countries in the Pacific-Basin. On balance, regression analysis on the nine markets shows negative relationships between stock returns in real terms and inflation in the short run, while co-integration tests on the same markets display a positive relationship between the same variables over the long run. The time path of the response of stock prices plotted against corresponding changes in consumer price indices validates this dichotomy in time-related response patterns of stock prices to inflation; namely, a blip of negative responses at the beginning changes to a positive response over a longer period of time. Stock prices in Asia, like those in the U.S. and Europe, appear to reflect a time-varying memory associated with inflation shocks that make stock portfolios a reasonably good hedge against inflation in the long run.     

The Fiscal and Monetary Linkage between Stock Returns and Inflation

Contrary to economic theory and common sense, stock returns are negatively related to both expected and unexpected inflation. We argue that this puzzling empirical phenomenon does not indicate causality. Instead, stock returns are negatively related to contemporaneous changes in expected inflation because they signal a chain of events which results in a higher rate of monetary expansion. Exogenous shocks in real output, signalled by the stock market, induce changes in tax revenue, in the deficit, in Treasury borrowing and in Federal Reserve “monetization” of the increased debt. Rational bond and stock market investors realize this will happen. They adjust prices (and interest rates) accordingly and without delay. Although expected inflation seems to have a negative effect on subsequent stock returns, this could be an empirical illusion, since a spurious causality is induced by a combination of: (a) a reversed adaptive inflation expectations model and (b) a reversed money growth/stock returns model. If the real interest rate is not a constant, using nominal interest proxies for expected inflation is dangerous, since small changes in real rates can cause large and opposite percentage changes in stock prices.     

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.     

Stock Returns Under High Inflation and Interest Rates: Evidence from the Brazilian Market

We analyze the relationship of high inflation and interest rates with stock returns in Brazil from May 1986 to May 2011, during which Brazil experienced subperiods of both high inflation (May 1986-June 1994) and relative monetary stability (July 1994-May 2011). The result in the total period is dominated by high inflation volatility, and the findings suggest a bidirectional relationship between stock returns and inflation. During the high-inflation subperiod, interest rates are relevant to explain future changes in inflation and stock returns. Under low inflation, movements in interest rates are better anticipated by equity investors, suggesting higher market efficiency than in high-inflation circumstances.     

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.     

Real Activity, Inflation, Stock Returns, and Monetary Policy

We find that contractionary monetary policy shocks generate statistically significant movements in inflation and expected real stock returns, and that these movements go in opposite directions. Since positive shocks to output precipitate monetary tightening, we argue that the countercyclical monetary policy process is important in explaining the negative correlation between inflation and stock returns. Examining the 1979–1982 period, we find that monetary policy tightens significantly in response to positive shocks to inflation, and that the impact of monetary policy shocks on stock returns is negative and volatile. Therefore, we see evidence that an “anticipated policy” hypothesis is at work.
