Inflation and inflation uncertainty in the ASEAN-5 economies

This study explores the linkage between inflation and inflation uncertainty in the ASEAN-5 countries over the period 1970:01–2007:12. Inflation uncertainty is estimated as a conditional variance in an AR(p)-EGARCH(1,1) model. Granger causality tests show that rising inflation increases inflation uncertainty and that rising inflation uncertainty increases inflation in all five countries. The ASEAN-5 have had low inflation rates relative to other emerging markets. Thus, our study shows that even in low inflation emerging markets inflation can lead to inflation uncertainty and uncertainty can lead to inflation. Given current inflationary pressures in these countries, our results warn of possible costs of not keeping inflation in check.     

中日两国汇率与股价指数的联动性分析

随着汇率限制和资本流动障碍的解除,一国的汇率与股市价格之间呈现出一种联动性。在对以利率为核心中介要素的传导机制进行理论分析的基础上,运用计量方法进行实证检验发现,外汇汇率与股市价格之间存在长期负相关关系。在长期内,我国上证综指是汇率变动的Granger原因。借鉴日本经验,我们不仅要看到人民币温和升值对股票市场价格的积极效应．同时更要重视股市泡沫破灭后的严重后果。中国可以采取循序渐进的汇率改革方式,坚持汇改的主动性、可控性以及渐进性,根据国际国内经济情况的变化适时、适度、逐步完善汇率机制,严控异常国际资本的流入,同时加强股市监管,努力营造公开、公正、透明的证券市场,为人民币将来的完全国际化提供一个市场制度基础。     

The effect of North Korean threats on financial markets in South Korea and Japan

This paper examines the effects of North Korean threats, as measured by the proprietary North Korean Threat Index (NKTI), on financial markets in South Korea and Japan. We examine the effects of the threats on stock markets, foreign exchange markets, and overnight interest rates. We consider causality in mean and variance tests to determine any link between the NKTI and financial variables. The causality-in-mean test results indicate the presence of a causal link running from North Korean threats to stock returns and exchange rate returns in both countries, but no significant link to the overnight interest rate in either country. The causality-in-variance test results indicate no significant impact emanating from North Korean threats. Integrating the North Korean economy into the global economy stands to eliminate these threats and thus to contribute to regional financial stability.     

Macroeconomic Variables and Stock Prices in Malaysia: An Empirical Analysis

The article investigates the dynamic interactions between seven macroeconomic variables and the stock prices for an emerging market, Malaysia, using cointegration and Granger causality tests. The results strongly suggest informational inefficiency in the Malaysian market. The bivariate analysis suggests cointegration between the stock prices and three macroeconomic variables – consumer prices, credit aggregates and official reserves. From bivariate error-correction models, we note the reactions of the stock prices to deviations from the long run equilibrium. These results are further strengthened when we extend the analysis to multivariate settings. We also note some evidence that the stock prices are Granger-caused by changes in the official reserves and exchange rates in the short run.     

Occupational Mobility Pattern in Chonju,Korea

This paper investigates the existence of the inter‐dependence between the Indian stock market and Asia's emerging markets since 1990. This study analyzes whether the MSCI Asian Index has significantly influenced the Bombay Stock Exchange Index before, during, and after the Asian financial crisis. To address this issue, the author first uses a rolling correlation, and conduct uni‐directional and bi‐directional causality tests using the Granger causality test. He then examines the impulse response functions and variance decompositions of forecast errors based on a VAR (vector auto‐regression) model. These tests provide evidence that the influence of the Asian market on the Indian market has increased during and after the Asian financial crisis. These results can be interpreted as evidence that the Indian market has been moving toward integration with other Asian markets.     

牛、熊市状况下人民币汇率与股价关系分析

文章分析了2005年7月人民币汇率改革以后牛熊市下人民币汇率和股票价格的关系,本文发现,在牛市期间,汇率和股票指数在滞后一期上是互为Granger因果关系的,在其余的各滞后期,汇率都是股票指数的Granger原因,而股票指数都不是汇率变动的Granger原因。从两者的互相影响的关系上看,两者在一定程度上互相影响,但是汇率变化对股指变化的影响比股指变化对汇率变化的影响的程度要更深。而在熊市情况下,人民币汇率和股票指数之间不存在协整关系。     

Financial market integration, stock markets and exchange rate dynamics in Eastern Europe

International capital flows in a system of flexible exchange rates will affect stock market dynamics and stock market developments should affect capital flows and the exchange rate respectively. In this analysis, four accession countries have been considered in order to examine any potential links between nominal stock market index and nominal exchange rate. For this purpose, monthly data were used. The cointegration concept was employed for testing long-term links and the VAR approach for short-term links. Finally, Granger causality tests were employed for the determination of the exogenous and endogenous variables. The results show that significant links exist between the stock market index and the foreign exchange rate for three countries, where for Poland, both long-term and short-term links exist. The other key aspect considered in this analysis is the stock market integration in Eastern European countries. Our analysis shows that the integration of the stock markets in Eastern European countries seems to be rather week except for the Hungarian stock market. This means that only the Hungarian stock market is integrated. A standard regression analysis reveals that the Hungarian market exhibits a strong co-movement with the benchmark market, i.e. the German stock market. Furthermore, there is a clear-cut result with respect to the dynamic of stock market synchronization. The degree of synchronization increased particularly in the period 2005–2008.

我国权证及标的证券日内交易模式研究——以五粮液为例

本文对五粮液正股(000858)及权证日内交易模式进行了实证研究,结果表明五粮液正股的波动率(L型)和交易量(U型)日内模式不同,认购权证均呈L型模式,认沽权证均呈U型模式;对正股和权证日内波动率进行的GRANGER检验表明,正股波动率是导致认购权证日内波动率形成的原因,但不是导致认沽权证的原因。文中对我国市场呈现这种日内交易模式的原因进行了初步探讨,认为主要是由于中国股票市场和权证市场所执行交易制度的不同和较高的交易成本。     

Fear of Floating: Korea's Exchange Rate Policy after the Crisis

The purpose of this paper is to explore the question of whether a free floating exchange rate regime is a viable option for Korea. This paper divides the sample period into three subperiods: pre-crisis, crisis, and post-crisis. We then analyze the causal relationships among both levels and volatility of three financial variables: exchange rates, interest rates, and stock prices. By using Granger causality tests and variance decomposition, our empirical results show that causal relations among the three variables are weak during the post-crisis period, and furthermore, shocks in other financial markets do not have a significant contribution to explain the variations of each variable's forecast errors. Based on these empirical findings, we infer that the Korean government, having adopted the de jure freely floating exchange rate regime, is still fearful of floating for various reasons. J. Japan.

Testing price-exchange rate noncausality: Results from a vector error correction model

Previous tests of the martingale property of the exchange rate have examined the random walk property of the exchange rate or have tested for Granger causality of the exchange rate by macroeconomic variables. Interestingly, if purchasing power parity (PPP) holds in the long run, causality tests should be conducted by estimating a vector error correction model which includes price levels. This paper conducts exchange rate causality tests employing vector error correction models and finds evidence that the Swiss exchange rate is Granger caused by lagged deviations in PPP and, hence, is Granger caused by prices.     

基于VAR模型对商品房价格影响因素的实证分析——以上海市房价为例

选取上海市房价作为研究对象,通过建立VAR模型来分析上海市地价、居民消费价格指数、房屋竣工面积、贷款利率、货币供应量及热钱流入对上海市商品房价格的影响。协整分析表明,各个变量之间具有长期的均衡关系。Granger因果检验表明,上海市商品房价格与地价之间存在双向的Granger因;货币供应量、贷款利率、房屋竣工面积、热钱与上海市商品房价格是单向Granger因;而上海市居民消费价格指数与商品房价格互不为Granger因。     

Contagion in the stock markets: The Asian financial crisis revisited

This paper presents empirical evidence of herding contagion in the stock markets during the 1997 Asian financial crisis, above and beyond macroeconomic fundamental driven co-movements. We analyze the cross-country time-varying correlation coefficients among the stock prices for the countries of Thailand, Malaysia, Indonesia, Korea, and the Philippines, between crisis and tranquil periods. Macromodels are constructed and implemented to capture the pure contagion effects on the markets. After controlling for the economic fundamentals for the five countries, the paper finds strong evidence of herding contagion.     

High‐Frequency Contagion of Currency Crises in Asia*

Using daily data from the Asian currency crisis, the present paper examines high‐frequency contagion effects among six Asian countries. The ‘origin’ (of exchange rate depreciation, or decline in stock prices) and the ‘affected’ (currencies, or stock prices) in the daily spillover relationship were defined and identified. Indonesia is found to be the main origin country, affecting exchange rates of other countries. Contrary to conventional wisdom, evidence of high‐frequency crisis spillover from the Thai exchange rate to other currencies was weak at best. There exists a high‐frequency contagion in stock markets among East Asian countries. Contagion coefficients are positively correlated with trade indices, indicating that investors lower their financial assessment of a country that has trade linkage to a crisis origin country within days, if not hours, of a shock.     

Exchange rates,stock prices,and money markets: evidence from Singapore

This paper uses a monetary approach to analyze the asymmetric asset-price movements (exchange rates and stock prices) in Singapore, a small open economy with managed exchange rate targeting. The Singapore dollar exchange rates vis-à-vis the developed countries’ currencies are negatively related to stock prices whereas the relationship between the Singapore dollar-Malaysian ringgit exchange rate and stock prices is positive instead. The pattern of asymmetry is explained by the relative exchange-rate elasticity of real money demand and real money supply and evidenced by the distributed-lag regression and VAR analysis. Furthermore, the distributed-lag regression of monthly data suggests that fiscal revenues as well as fiscal expenditures exert positive influences on stock prices.     

Testing for cointegration with threshold effect between stock prices and exchange rates in Japan and Taiwan

This paper empirically investigates the exchange rate effects of the New Taiwan dollar against the Japanese Yen (NTD/JPY) on stock prices in Japan and Taiwan from January 1991 to Mach 2008. Our study employs the newly threshold error-correction model (TECM) elaborated by Enders and Granger [Enders, W., Granger, C.W.F., 1998. Unit-root tests and asymmetric adjustment with an example using the term structure of interest rates. Journal of Business Economics & Statistics 16, 304–311] and Enders and Siklos [Enders, W., Siklos, P.L., 2001. Cointegration and threshold adjustment. Journal of Business Economics & Statistics 19, 166–176], assuming the nature of the relationship between the variables is on the basis of non-linearity. The empirical evidence suggests that there is a long-run equilibrium relationship between NTD/JPY and the stock prices of Japan and Taiwan during the time period investigated. However, an asymmetric threshold cointegration relationship only exists in Taiwan’s financial market. Furthermore, we extend our research by taking into account the effect of the U.S. exchange rate specifically on Taiwan’s financial market. This research also finds a long-term equilibrium and asymmetric causal relationships between NTD/USD and the stock prices of Taiwan. In addition, the results of TECM Granger-Causality tests show that no short-run causal relationship exists between the two financial assets considered for both countries’ cases. However, in the long run a positive causal relationship running from either the Japan or U.S. exchange rate to the stock prices of Taiwan strongly argues for the traditional approach.     

Analysis of the Interactive Linkages Between Gold Prices,Oil Prices,and Exchange Rate in India

This study investigates the co-movements and linkages among gold prices, oil prices, and Indian rupee–dollar exchange rates for the time span of 12 January 2004 to 30 April 2015 to investigate whether Indian economic policy-makers should detach financial policies from energy policies. Various econometrical methods such as Johansen’s cointegration test, vector autoregressive model, Granger causality test, and impulse response were used to explain the co-movements among the variables. We find that gold prices, oil prices, and rupee–dollar exchange rates stay substantially independent from each other, which denotes energy policies and financial policies must be detached.     

Asset Price Bubbles: Existence,Persistence and Migration

Econometric tests are performed for the detection and migration of asset‐price bubbles in the housing, currency and stock markets of seven countries. This set of countries includes both developed and emerging economies that have good historical data on housing prices. Our empirical results suggest that this type of exuberant behaviour in prices occurs more frequently in the housing market than in the currency and stock markets. Additionally, we find significant evidence of bubble migration across markets within some of the studied countries.     

Exchange Rate Regimes: Middling Through

Abstract

The appropriate exchange rate regime, in the context of integration of currency markets with financial markets and of large international capital flows, continues to be a policy dilemma. It is found that the majority of countries are moving towards somewhat higher exchange and lower interest rate volatility. Features of foreign exchange (forex) markets could be partly motivating these choices. A model with noise trading, non-traded goods and price rigidities shows that bounds on the volatility of the exchange rate can lower noise trading in forex markets; decrease fundamental variance and improve real fundamentals in an emerging market economy (EME); and give more monetary policy autonomy. Central banks prefer secret interventions where they have an information advantage or fear destabilizing speculation. But in the model discussed in this article, short-term pre-announced interventions can control exchange rate volatility, pre-empt deviations in prices and real exchange rates, and allow markets to help central banks achieve their targets. The long-term crawl need not be announced. In conclusion, the regime's applicability to an EME is explored.
