Conflicts of interest and china's A-Share underpricing

The extremely high A- share underpricing in China's primary market provides us with a very interesting area of empirical research. Previous studies on China's IPO underpricing have been suggestive, but in-conclusive. We investigate the A- share underpricing by employing the most recent data available. A significant decline in A- share underpricing is found in 2003 relative to previous years (and much less than that recorded in the literature to date). We examine the validity of previous A- share underpricing models, reported in the literature, and find a statistically significant structural break in the data during 2003 when these models are specified. We further explore conflicts of interest in the Chinese IPO market and specify an alternative class of models to further examine this change in observed market behaviour. Our results suggest that a contract with high underwriter's fee leads to less A- share underpricing. Our results also suggest that the asymmetric information hypothesis does not apply in the Chinese !PO market in 2003. Overpricing by the secondary market and the trading activity on the first trading day are the main functions of the A- share underpricing. This study has important implications such as guiding the Chinese government policy regarding the regulations of Initial Public Offering.

Consumer choice, information product quality, and market implications

The paper concerns with the peculiarities of consumer choice in information product markets. This is a multidisciplinary study based on both information system research and microeconomic theory. An extension is introduced to the conventional general theory of consumer choice for explicitly taking into account the impact of information product quality on consumer behaviour. Multiple quality characteristics, considered against the price of product, are an essential reason for consumer choice of high tech product in general and information product in particular. We assume that consumers are able to aggregate their preferences of multiple product characteristics into a product preference order. On the supply side, the product quality characteristics incur costs. In the case of information product, those costs are the costs of the first copy, and marginal costs are near zero. All of the above constitute the distinctive characteristics of the competitive mechanism in the digital economy and in information product markets. A model, based on the game theory is used to consider two special cases. The first one deals with monopolistic competition for a share of the market with a limited number of customers. Conditions are derived for IT firm survival. The second one considers conditions at which a monopoly is able to successfully introduce a new version if its information product.

External monitoring, managerial ownership and form performance in Malaysian capital market: a GMM based panel data approach

This study re-examines whether the structure of share ownership by both directors and institutional ownership provides explanation for firm performances. These relationships are modelled and estimated using GMM based dynamic panel data over a period from 1997 to 2001 with a sample of 100 CI components companies listed on Main Board of Malaysia. The findings provide strong evidence of simultaneity between firm performance and managerial ownership. Although an insignificant relationship between firm performance and institutional ownership is~ observed, the institutional holdings provide strong substitute for managerial ownership with a strong negative relationship between managerial ownership and institutional ownership. This is in line with the managerial incentive hypothesis, which suggests that manager's share in the firm's ownership leads to better performance and the monitoring substitute hypothesis, which suggests that managerial ownership could be effectively replaced by institutional ownership.

Asymmetric recognition of good and bad news at Malaysian capital market : a pre and crisis analysis

The aim of this paper is to analyze the asymmetric recognition of good and bad news on reported earnings of Malaysian-listed firms. The study uses both descriptive and regression analyses to ascertain whether there is a contemporaneous relationship between news (good and bad) and reported earnings. The analysis is based on a sample of 150 firms listed on the Bursa Malaysia Index over a period of 10 years, from 1990 to 2000. Two regression models were adopted based on Basu (1997) and Giner and Rees (2001). The first model aims to capture asymmetric recognition of good and bad news into reported earnings while the latter model is developed to capture both asymmetric recognition of information shock and permanent earnings effect on contemporaneous earnings. The evidence from this study reported the steady increase in earnings per share till 1997. However, a drastic decline was observed for the period 1997 to 1999 because of Asian financial crisis. The findings from the regression model one suggested that the asymmetric recognition of good news was more prominent during the good time compare to bad time and vice versa. The findings from model two also suggested that autoregressive effect of permanent effect was very prominent both for crisis and non crisis periods.

Portfolio diversification and share price behavior : some evidence from the Taiwan Stock Exchange

This dissertation consists of four separate but closely related studies which investigate different aspects of share price behavior on the Taiwan Stock Exchange over the period 1980-89: 1.The benefits of diversification available to investors using the Markowitz model and the Single Model Index. 2. The applicability of the CAPM to the TSE over the decade. 3. Regularities in proce sequences. 4. Market reaction to the announcements of stock dividends, right issues and combinations of both.

Market based performance : do ownership structures, or firm policy choice matter?

This study examines whether the structure of share ownership or firm's dividend and debt policies provide explanation for firm performances in Malaysia. Firm performance, measured as Tobin's Q is modelled in a dynamic panel framework to estimate effects of director ownership, family ownership, foreign ownership, and firm's dividend and debt policy. The generalised methods of moments (GMM) method is used to estimated the models for 80 CI components companies listed on Main Board of Malaysia observed from 1999 to 2002. The findings reveal strong evidence of positive impact of firm's dividend and debt policy on firm performance. However, ownership structure seems to be less important for market based performance of Malaysian firms: These results are expected to provide guidelines to the investors regarding the significance of firm dividend policy, leverage policy and market to book value ratio as some of the key sources of value creation for Malaysian listed firms.

Do investors value disclosed versus recognised employee share options differently?

Prior research provides evidence consistent with footnote disclosures are being valued by investors. However, there are arguments as to whether the market would acquire and/or process disclosed versus recognised information in the same way. Prior studies have been inconclusive on the findings. This research provides evidence for the conditions under which differential valuation exist. Three factors are examined. First, I investigate whether the differential valuation is related to the reliability of the accounting estimates. Second, due to higher processing costs on disclosures relative to “recognised” information, I investigate whether sophistication of investors contributes to the differential valuation. Finally, I examine systematic biases arisen from how investors process information due to limited attention paid to disclosures. The results show that the market does process information in a complicated way. Investors discern the reliability of accounting estimates and value them differently when processing the information.

Short-term impacts of the cricket match performances on national share markets – a case study of India and Australia

We investigate the impact that investor sentiment can have on stock market following performances by the national cricket teams of India and Australia in one-day cricket matches from 1990 to 2011. Motivated by previous findings of cricket’s impacts on stock markets, this study expands on previous research by investigating whether performances of individuals within the teams can also have an impact on their respective leading stock indices. Using an event study, we find no evidence of player or team performances significantly impacting the stock or futures markets. However, we find evidence of a ‘mood effect’ of poor performance by key players of national cricket teams in terms of significant drop in trading volumes in the following day. Our research poses and statistically examines some interesting questions and opens up the field for further research on this intriguing topic of sporting event impacts on national economies.

Non-tradable share reform, liquidity, and stock returns in China

This article studies the influence of the non-tradable share reform in the cross-section of stock returns in China. Prior research has generally neglected this important development in the Chinese stock market. We find that the firm-specific illiquidity measures that reflect direct transaction costs, price impact and difficulties in trading immediacy, exhibit a positive and significant relationship with stock returns. These effects are particularly pronounced after the non-tradable share reform. Furthermore, in the post-reform era, portfolios with high illiquidity (i.e. high relative bid-ask spread, high Amihud illiquidity, low Amivest liquidity ratio) significantly outperform portfolios with low illiquidity, controlling for size, and book-to-market effects.

Call auction transparency and market liquidity: Evidence from China

This paper uses the natural experiment offered by the Shanghai Stock Exchange to investigate the impact of opening call auction transparency on market liquidity. We find that the dissemination of indicative trade information during the pre-open call auction session leads to an overall improvement in stock liquidity in the continuous trading session. Bid-ask spreads narrow in the first trading hour because adverse selection risk fell significantly and there is less price volatility in the continuous market. This effect is greater for actively traded securities than illiquid securities. Our findings are robust for different lengths of sample period, different lengths of trading hours after market open, and stocks that had (and had not) reformed the share split structure during our research period.

Does CEO pay dispersion matter in an emerging market? Evidence from China’s listed firms

This paper examines how the institutional features of emerging economies (i.e., government ownership, political connections, and market reform) influence CEO pay-dispersion incentives. Consistent with our expectation, we find that CEO pay dispersion generally provides a tournament incentive in China's emerging market, as it is positively associated with firm performance. In addition, tournament incentives are weaker where firms are controlled by the government and where the CEO is politically connected, but it became stronger after the China's split-share structure reforms. Further, we find that in state controlled firms the satisfaction gained by meeting multiple economic and social goals largely reduces the effectiveness of tournament incentives, while the managerial agency problems inherent in private firms might mitigate them.

Controlling shareholder, expropriations and firm’s leverage decision: Evidence from Chinese Non-tradable share reform

This paper examines the effect of excess control rights on the leverage decisions made by Chinese non-SOEs before and after the Non-tradable share reform (NTS reform). We find that firms with excess control rights have more excess leverage and their controlling shareholders use the resources for tunneling rather than investing in positive NPV projects. We also find that excess leverage in firms with excess control rights decreases and the market reaction to announcements of related party transactions are more positive after NTS reform. This confirms that tunneling by the controlling shareholders actually reduced. We argue that in emerging markets where legal protection for creditors and shareholders is weak, controlling shareholders borrow excess debt to tunnel through inter-corporate loans and related party transactions. Furthermore the privatization of these economies can reduce the controlling shareholders' tunneling activities and associated excess leverage which destroys firm value.

Market-based sensor relocation by robot team inwireless sensor networks

Randomly scattered sensors may cause sensing holes and redundant sensors. In carrier-based sensor relocation, mobile robots (with limited capacity to carry sensors) pick up additional or redundant sensors and relocate them at sensing holes. In the only known localized algorithm, robots randomly traverse field and act based on identified pair of spare sensor and coverage hole. We propose a Market-based Sensor Relocation (MSR) algorithm, which optimizes sensor deployment location, and introduces bidding and coordinating among neighboring robots. Sensors along the boundary of each hole elect one of them as the representative, which bids to neighboring robots for hole filling service. Each robot randomly explores by applying Least Recently Visited policy. It chooses the best bid according to Cost over Progress ratio and fetches a spare sensor nearby to cover the corresponding sensing hole. Robots within communication range share their tasks to search for better possible solutions. Simulation shows that MSR outperforms the existing competing algorithm G-R3S2 significantly on total robot traversed path and energy, and time to cover holes, slightly on number of sensors needed to cover the hole and number of sensor messages for bidding and deployment location sharing.
