Foreign dependence of individual stock prices: The role of aggregate product market developments

In this paper, we analyze the role of aggregate variables in the transmission from international stock price developments to individual domestic stock prices in a small open stock market. In particular, a theoretical and econometric model is used to determine whether international aggregate product market developments explain observed differences in foreign dependence among individual Belgian stocks. The results suggest that, except for the stocks of some internationally oriented companies, expected international production is not the most important explanatory variable and that an estimation model of aggregate fundamentals explains only part of individual stock price adjustments.     

Linkage between stock volatility and corporate bond yield spread in Thailand

This paper studies the relationship between stock volatility and corporate bond yield spread in Thai market by using Campbell and Taksler （2003） panel data regression approach. The results show that the equity volatility＇s variables, such as finn＇s idiosyncratic risk, market risk, individual stock return and market return, are matter to explain the corporate bond yield spread. Surprisingly, these variables could explain the spread better than credit rating variables. Furthermore, during bear market period, only corporate bond yield spreads in financial finns are increasing significantly. Some of the deterministic yield spread parameters such as level and slope of interest rate also alter from bull market period.     

Intraday return and volatility spillover mechanism from Chinese to Japanese stock market

We analyze the mechanism of return and volatility spillover effects from the Chinese to the Japanese stock market. We construct a stock price index comprised of those companies that have substantial operations in China. This China-related index responds to changes in the Shanghai Composite Index more strongly than does the TOPIX (the market index of the Tokyo Stock Exchange). This result suggests that China has a large impact on Japanese stocks via China-related firms in Japan. Furthermore, we find evidence that this response has become stronger as the Chinese economy has gained importance in recent years.     

Commodity prices and global economic activity

Commodity prices provide useful information about current and future global economic activity. First, we show that overall commodity prices indeed tend to comove with economic activity. Second, we try to extract the global demand factor(s) using many commodity prices. While commodity prices reflect both demand and supply factors, by relying on a wide variety of commodity prices, supply shocks can be filtered out as they tend to be commodity-specific idiosyncratic shocks except for widespread supply disruptions confined to a few historical periods. In this paper, we then show that factors extracted from commodity prices movement contain useful information to nowcast and forecast global GDP and industrial production.

The state of the market and the contrarian strategy: evidence from China's stock market

Using the most comprehensive weekly dataset of ‘A’ shares listed on the Chinese stock market, this paper examines short-term contrarian strategies under different market states from 1995–2010. We find statistically significant profits from contrarian strategies, especially during the period after 2007, when China (along with other countries) experienced an economic downturn following the worldwide financial crisis. Our empirical evidence suggests that: (1) no significant profit is generated from either momentum or contrarian strategies in the intermediate horizon; (2) after microstructure effects are adjusted for, contrarian strategies with only four to eight weeks holding periods based on the stocks’ previous four to eight week's performance generate statistically significant profits of around 0.2% per week; (3) the contrarian strategy following a ‘down’ market generates higher profit than those following an ‘up’ market, suggesting that a contrarian strategy could be used as a shelter when the market is in decline. The profits following a ‘down’ market are robust after risk adjustment.     

Global food prices and monetary policy in an emerging market economy: The case of India

This paper investigates a perception in the political debates as to what extent poor countries are affected by price movements in the global commodity markets. To test this perception, we use the case of India to establish in a standard SVAR model that global food prices influence aggregate prices and food prices in India. To further analyze these empirical results, we specify a small open economy New-Keynesian model including oil and food prices and estimate it using observed data over the period 1996Q2 to 2013Q2 by applying Bayesian estimation techniques. The results suggest that a big part of the variation in inflation in India is due to cost-push shocks and, mainly during the years 2008 and 2010, also to global food price shocks, after having controlled for exogenous rainfall shocks. We conclude that the inflationary supply shocks (cost-push, oil price, domestic food price and global food price shocks) are important contributors to inflation in India. Since the monetary authority responds to these supply shocks with a higher interest rate which tends to slow growth, this raises concerns about how such output losses can be prevented by reducing exposure to commodity price shocks.     

Tax reforms and stock return volatility: The case of Japan

Although global financial turmoil in recent years has resulted in renewed interest in taxing financial markets, the existing evidence is inconclusive regarding the effect of stock transaction taxes (STT) on stock return volatility. In this respect, Japan provides an excellent opportunity to address the issue, as the country enacted major tax reforms during the long recession beginning in the early 1990s, not only abolishing STT in 1999, but also reducing the capital gains and dividend taxes in 2003. The present paper exploits these tax reform episodes and examines whether and how they affected stock return volatility. In so doing, it employs GARCH-type models using standard daily stock data, as well as HAR models based on realized volatility constructed from high-frequency, intraday data. The estimation results are consistent with the views that, in line with some earlier findings, the STT abolition in 1999 reduced volatility, and that the tax reforms in 2003 also reduced volatility through a cut in the dividend tax, but not in the capital gains tax.     

Short selling and stock prices with regime switching in the absence of market makers: The case of Japan

This paper investigates the relation between short selling and stock price at an aggregated market level. In order to study the differential impact of market microstructure on short selling, the data from Japanese stock markets are used. Both traditional regression and Markov switching models are used to compare Japanese results to those of U.S. and to admit non-stationary relation between short selling and stock price, respectively. Particularly, relatively long period (1978–2002) of analysis including bullish and bearish periods gives a good testable bed for studying the effect of short selling on stock price according to market condition. The empirical findings reveal that percentage change of short interests has a statistically significant positive relation with stock returns. It gives regulators policy implication that short selling is not a destabilizing activity, but an acceptable form of trading even in the absence of market makers. And short selling information cannot be used as an indicator for predicting future stock markets.

Populists versus theorists: Futures markets and the volatility of prices

In this paper, the divergence between popular and professional opinion on speculation in general and futures markets in particular is explored. Along the way, a synopsis of prevailing popular attitudes on futures markets is presented, and an outline of a formal model of futures markets and its implications for commodity price volatility are sketched. The heart of the analysis is drawn from the historical record on the establishment and prohibition of futures markets. Briefly, the results presented in this paper strongly suggest that futures markets were associated with—and most likely caused—lower commodity price volatility. The paper concludes with a discussion of potential sources of popular antagonism against futures markets.     

Scaling risk and the square-root-of-time rule in the emerging markets： Evidence from the Chinese stock market

This paper examines the square-root-of-time rule that frequently used in volatility estimation to the Chinese stock market that comprises Shanghai and Shenzhen stock market. The Jarque-Bera test conclusively rejects normal distribution of both stock market returns, while the Hurst analysis indicates both stock market returns does not follow a random walk. Furthermore, the tests for volatility scaling indicate volatility of both stock market returns do not scale according to the square-root-of-time rule and lead to bias in risk estimation. Henceforth, the study urges more alternative methods in risk management that suitable for the emerging Chinese stock market.

Sociopolitical instability,volatility, and the bid-ask spread: Evidence from the free market for dollars in Poland

This paper provides empirical evidence that the weekly bid-ask spread in the Polish free foreign exchange market is heavily affected by the intensity of sociopolitical unrest in this country. A GARCH model is estimated to study the volatility of the free market for dollars in Poland from the third week of October 1988 to the fourth week of January 1990. This period is interesting and important because it includes social and political events under two different government regimes. Empirical evidence suggests that significant sociopolitical turmoil appears to increase the volatility of the market and consequently create substantial changes in the spread. The results of this paper may represent valuable information for other reforming countries.

The spirit of capitalism, stock market bubbles and output fluctuations

This paper presents a representative agent model in which stock market bubbles cause output fluctuations. Assuming that utility depends directly on wealth, we show that stock market bubbles arise if the marginal utility of wealth does not decline to zero as wealth goes to infinity. Bubbles can affect output positively or negative depending on whether the production function exhibits increasing or decreasing returns to scale. In sunspot equilibria, the bursting of a bubble is followed by a sharp decline in output one period later. Various numerical examples are given to illustrate the behavior of stochastic bubbles and the relationship between bubbles and output.     

Transmission of Stock Prices and Volatility from the Influential Major Markets on the Emerging Market: A Case Study of the Korean Stock Market

Abstract

This study investigates how the 1997 crisis has changed the Korean market by focusing on price and volatility spillovers from the US, Chinese, and Japanese markets. Using the exponential general autoregressive conditional heteroskedastic (EGARCH) model, new information on stock prices originating in the US market was transmitted to the Korean market for all periods. The price spillover effect from the Japanese market to the Korean market became stronger from the crisis period. Asymmetry in the spillover effect on market volatility was more pronounced in the Korean market after the financial crisis.     

Oil price shocks and producer prices in Taiwan: an application of non-linear error-correction models

This study estimated the short-term and long-term pass-through effects of oil prices on inflation in Taiwan from 1981M1-2011M5, employing the producer price general index and various basic sub-indices for evaluation. The empirical results show that oil prices have long-term and short-term pass-through effects on Taiwan’s producer price indices. Moreover, producer prices have significant non-linear error-correction relationships with the oil price, output and wages, suggesting asymmetric and time-variant properties of error correction. When the deviation of price in the equilibrium is greater, the error-correction adjustment will be faster. Our findings could therefore enable the monetary authorities and manufacturers to formulate a more effective policy from the oil price shocks.
