Does Ownership Affect a Firm's Performance and Default Risk in Jordan?

This paper examines the impact of ownership structure on firm performance and the default risk of a sample of 59 publicly listed firms in Jordan from 1989 to 2002. The main findings were: (1) ownership structure has significant effects on the accounting measure of performance return on assets (ROE). (2) Government shares are significantly negatively related to the firms performance ROE. (3) Defaulted firms have a high concentration ownership compared with non-defaulted firms. Also high foreign ownership firms have a low incidence of default. (4) Government ownership is significantly negatively related to the firms probability of default. (5) Both mix and concentration ownership structure data can be used to predict the probability of default as the largest five shareholders (C5) and government ownership fraction (FGO) are significantly negatively correlated with the probability of the default. These results further suggest that reducing government ownership can increase a firms performance and but will also cause some firms to go bankrupt, at least in the short term.

Does political capital create value in the IPO market? Evidence from China

This study examines the value of political capital in the Chinese IPO market. We find a positive relationship between a politically connected executive and the probability of IPO approval of entrepreneurial firms. We further identify that shareholders value those connections and give a market premium to connected firms after the firms go public. We provide evidence that other types of political capital gained through external sources, such as politically connected sponsors and PE investors, also bring benefits to the firms in their IPO approval, and these connections substitute for the effect of the executives political connections on IPO approval. We argue that in emerging markets where government intervention is still prevalent, political capital does create value and entrepreneurial firms usually build political capital to facilitate their access to the IPO market, although other types of political capital do not bring further benefits into the post-IPO market.

Market efficiency and the returns to simple technical trading rules: new evidence from U.S. equity market and Chinese equity markets

Numerous studies in the finance literature have investigated technical analysis to determine its validity as an investment tool. This study is an attempt to explore whether some forms of technical analysis can predict stock price movement and make excess profits based on certain trading rules in markets with different efficiency level. To avoid using arbitrarily selected 26 trading rules as did by Brock, Lakonishok and LeBaron (1992) and later by Bessembinder and Chan (1998), this paper examines predictive power and profitability of simple trading rules by expanding their universe of 26 rules to 412 rules. In order to find out the relationship between market efficiency and excess return by applying trading rules, we examine excess return over periods in U.S. markets and also compare the excess returns between U.S. market and Chinese markets. Our results found that there is no evidence at all supporting technical forecast power by these trading rules in U.S. equity index after 1975. During the 1990s break-even costs turned to be negative, –0.06%, even failing to beat a buy-holding strategyin U.S. equity market. In comparison, our results provide support for the technical strategies even in the presence of trading cost in Chinese stock markets.

Causality between exports and economic growth: the empirical evidence from Shanghai

The export-led growth hypothesis is tested using monthly time series data for Shanghai (one of the major exporting provinces in China) using the Granger no-causality procedure developed by Toda and Yamamoto (1995) in a vector autoregresion (VAR) model. Three distinct features in this paper stand out: first, the study of the export-led growth hypothesis using the case of Shanghai is the first attempt. Second, the paper follows Riezman, Whiteman and Summers (1996) to test the hypothesis while controlling for the growth of imports to avoid a spurious causality result; and finally, the use of the methodology by Toda and Yamamoto is expected to improve the standard F-statistics in the causality test process. The research finds a one-way Granger causality running from GDP to exports.

Ownership and ownership concentration: which is important in determining the performance of China's listed firms?

This article investigates the impact of ownership and ownership concentration on the performance of China’s listed firms. By recognizing the differences between ownership and ownership concentration and between total ownership concentration and tradable ownership concentration, we find that ownership concentration is more powerful than any category of ownership in determining firm performance; tradable ownership concentration has a more significant and positive influence on firm performance than total ownership concentration; the highest level of firm performance is approached when a firm is characterized by both total ownership concentration and tradable ownership concentration. Thus, we propose a conclusion that ownership concentration enhances firm performance regardless of who the concentrated owners are.

Are Chinese stock markets increasing integration with other markets in the greater China region and other major markets

This paper investigates the cointegrating and long-term causal relationships between the Shanghai A and B-share market, and between these two markets and the Hong Kong, the Taiwanese, the Japanese and the US market of two sub periods between July 1993 and March 2007. On the basis of a new Granger non-causality test procedure developed by Toda-Yamamoto (1995) and Johansens (1988) cointegration test, my results suggest that a long-term equilibrium relationship measured by cointegration has been merged between the Chinese A-share market and the other markets in greater China region as well as the US market during the post-crisis period which covers the period since Chinese A-share market was opened to the Qualified Foreign Institutional Investors (QFII) in 2002. I also found that the Shanghai A-share market uni-directionally Granger-causes the other regional markets after the Asian financial crisis, while the A-share market and Hong Kong H-share market have had a significant feedback relationship since then. However, I found no evidence there has been cointegrating relationship between Shanghai B-share market and any other market ever since the B-share market was opened to the local retail investors in 2001.

The effect of ownership structure on leverage decision: new evidence from Chinese listed firms

This paper examines the effect of state control and ownership structure on the leverage decision of firms listed in the Chinese stock market. Our results show that state-owned enterprises (SOEs) have higher leverage ratios than non-SOEs, and SOEs in regions with a poorer institutional environment have higher leverage ratios than SOEs in better regions. We also show that the largest shareholding (the percentage of shares held by the largest shareholder) in the SOEs has a negative relationship with the leverage ratio, while the largest shareholding in non-SOEs has a non-linear relationship with the short-term and long-term debt ratios. Finally, this study also shows that the share split reform and the improvement of institutional environment both weaken the negative relationship and strengthen the positive relationship between largest shareholding and leverage of SOEs and non-SOEs to some extent. This paper documents how the financing behaviour of SOEs is more influenced by government intervention, while the financing behaviour of non-SOEs is more market oriented.

The Relationship between Stock Returns and the Foreign Exchange Rate: The ARDL Approach

This study employs the ARDL cointegration approach in order to examine the impact of financial liberalization on the relationships between the exchange rate and share market performance in China. We discovered that cointegration has existed between the Shanghai A Share Index and the exchange rate of the renminbi against the US dollar and Hong Kong dollar since 2005, when the Chinese exchange rate regime became a flexible, managed, floating system. We found that both the exchange rate and the money supply influenced stock price, with a positive correlation. We further show that the money supply increase was largely caused by a huge ‘hot money’ inflow from other countries in recent years. After local currency appreciation, hot money, followed by the money supply increase, pushed the market into a high level, based on expectations regarding the local currencys further appreciation.

Interaction among China-related stocks: evidence from a causality test with a new procedure

The purpose of this study is to investigate a causal relationship among five different indices of shares issued by Chinese firms, A-, B- and H-shares listed in China and Hong Kong. This article re-examines the interactions among these China-related stocks using daily time series data by constructing a vector autoregresion (VAR) model. A new Granger no-causality testing procedure developed by Toda and Yamamoto was applied to test the causality link among these five stock indices. The results suggest that the ‘closed’ B-share markets in Shanghai and Shenzhen exhibit causality relations with each other during the entire period between 1993 and 1999 but this pattern does not exist within A-share markets. Furthermore, evidence is also found of Granger causality running from Hong Kong H-shares to B-shares in Shanghai and Shenzhen, and from Shanghai B-shares to all the rest Chinese markets for the post-1996 period.

Does Control-Ownership Divergence Impair Market Liquidity in an Emerging Market? Evidence from China

This paper examines how institutional characteristics of emerging economies influence the effect of control-ownership divergence on market liquidity. We find that the divergence is negatively associated with liquidity and that this negative relationship is more pronounced in firms with more severe agency problems and information asymmetry. We argue that in an emerging market, the negative effect of the divergence on liquidity is worsened by state ownership and poorer shareholder protection, both of which result in more severe agency conflicts; we also find, however, that this effect is alleviated by the NTS reform, which aligns the interest of different shareholders.
