Foreign ownership and auditor choice

We take advantage of the unique institutional background of the B-share stock market in China to explore the impact of foreign investors on auditor choice. Our results show that the percentage of B-share firms audited by Big 4 auditors has decreased with both economic and statistical significance since the segmented B-share market was opened to domestic investors in 2001. We find that the negative effect of opening the B-share market on demand for high audit quality is more pronounced for firms with greater decreases in foreign ownership and for firms with strong incentives to be opaque, such as those in a weak institutional environment, firms with more “other receivables,” firms with more related-party transactions, and firms with political connections. Additional analysis shows that our results are not driven by the concurrent decline in capital-raising activities in the B-share market.     

The informativeness of domestic and foreign investors’ stock trades: Evidence from the perfectly segmented Chinese market

This paper uses the perfect market segmentation setting in China's stock market to compare the information content of the stock trades of domestic and foreign investors. We study 76 firms that issue both A-shares (for domestic investors) and B-shares (for foreign investors) and compare the price discovery role of the two segmented markets in China. Before Feb 19, 2001, the A-share market led the B-share market in price discovery, as the signed volume and quote revision of the A-share market had strong predictive ability for B-share quote returns, but not vice versa. After Feb 19, 2001, because some domestic investors were allowed to invest in the B-share market, we find evidence for a reverse causality from the B-share to the A-share market. Nevertheless, the [Hasbrouck (1995). One security, many markets: determining the contributions to price discovery, Journal of Finance 50, 1175–1199.] information share analysis reveals that A-shares continue to dominate the price discovery process.     

STOCK MARKET OPENNESS AND MARKET QUALITY: EVIDENCE FROM THE SHANGHAI–HONG KONG STOCK CONNECT PROGRAM

We study the impact of capital market openness on high-frequency market quality in China. The Shanghai–Hong Kong Stock Connect program (SHHKConnect) opens China's stock market to foreign investors and offers a natural experiment to investigate this question. Using a difference-in-differences approach, we find that market liberalization leads to lower quoted spread, lower effective spread, lower market depth, and higher short-term volatility. Our findings imply that opening the markets to more sophisticated foreign investors is associated with higher competition and more cross-market arbitrage activities, narrowing the spread and reducing liquidity providers’ profits, but increasing the price impact and short-term volatility of connected stocks.     

The effect of market segmentation on stock prices: The China syndrome

China has an A-share market that is open only to local investors and a B-share market that is open only to foreign investors. Contrary to what has been observed in other markets with a similar segmented structure, the China B shares trade at a discount relative to the A shares. We show that the phenomenon can still be explained by basic economic principles. Specifically, the existence of the H-share and the “red-chip” markets in Hong Kong provide good substitutes for the B-share market. We find that when more H shares and red chips are listed in Hong Kong, the B-share discount becomes larger. This is consistent with the model of differential demand elasticity proposed by Stulz and Wasserfallen (Stulz, R., Wasserfallen, W., 1995. Review of Financial Studies 8, 1019–1057).     

The Post-Issue Market Performance of Initial Public Offerings in China's New Stock Markets

In this paper, we investigate the post-issue market performance of initial public offerings (IPOs) in China's new stock markets. Our analysis focuses on whether and how institutional features unique to China differentially affect IPO performance. These features include the existence of dual-class shares for the same underlying firms (A-shares issued to domestic investors and B-shares issued to foreign investors) and the unusually long time lag between the offering and listing dates. Our sample consists of 277 A-share and 65 B-share IPOs that were listed on China's new stock markets during the 1992–1995 period. Our study has a number of interesting results. First, A-share IPOs are much more severely underpriced during the initial return period than B-share IPOs. Second, B-share IPOs underperform A-share IPOs (and the market) during the post-issue periods for up to three years. Third, the results of multivariate regression analyses strongly suggest that economic factors determining the post-issue performance of IPOs differ across the A-share and B-share samples.     

Stock market openness and analyst forecast bias

Biases in analysts’ forecasts can be reduced not only through regulation but also through market mechanisms. In 2014, China launched the Shanghai-Hong Kong Connect program, which opened part of its domestic equity market to foreign investors. The implementation of this program provides a quasi-natural experimental setting to explore whether stock market openness plays a governance role in brokerage firms and minimizes their affiliated analysts' forecast biases. We find that the participation of foreign institutional investors mitigates the forecast biases of affiliated analysts. We also show that these analysts exert more significant effort by conducting more site visits. Our findings suggest that market liberalization can help improving the quality of analysts’ forecasts.

Stock market liberalization and innovation

We investigate the effect of stock market liberalization on technological innovation. Using a sample of 20 economies that experience stock market liberalization, we find that these economies exhibit a higher level of innovation output after liberalization and that this effect is disproportionately stronger in more innovative industries. The relaxation of financial constraints, enhanced risk sharing between domestic and foreign investors, and improved corporate governance are three plausible channels that allow stock market liberalization to promote innovation. Finally, we show that technological innovation is a mechanism through which stock market liberalization affects productivity growth and therefore economic growth. Our paper provides new insights into the real effects of stock market liberalization on productivity growth and the economy.     

Decomposing the Bid-Ask Spread in a Segmented Equity Market: Analyzing Chinese A Shares Versus B Shares

Because of a regulatory policy change in February 2001, the segmentation of the Chinese stock market significantly decreased. Using this event, we show that the Chinese A-share market is more informationally efficient than the B-share market, both before and after the opening of the B-share market. Furthermore, after the event, both the adverse selection and the order-processing component of B shares decreased, as a result of a larger investor base and possibly a lower proportion of informed investors. This study thus sheds new light on the market segmentation and its effect on transaction costs.     

Further evidence on the efficiency of the Chinese stock markets: A note

This paper examines the efficiency of the Chinese A-share and B-share markets following the deregulation of the B-share market which widened ownership to include domestic investors. Applying parametric and non-parametric variance ratio tests to the daily data of 370 shares over 1996–2005, the paper finds that A-shares are more efficient than B-shares, although the efficiency of both markets has improved following the regulatory change. Overall, the results suggest that the Chinese stock markets are characterised by information asymmetry, although the timely access to high quality information that domestic investors enjoy has improved the efficiency of the B-share market.     

A corporate governance explanation of the A-B share discount in China

B-shares listed in China are traded at substantial discounts to their corresponding A-shares although they have identical rights. We offer a governance explanation and suggest that relative to domestic investors, foreign investors care more about a firm’s governance quality. Results are supportive, as the B-share price discount is higher for firms that have weaker governance characterized by 1) higher ownership concentration, 2) ineffective boards with a higher proportion of directors appointed by the parent company, 3) lower dividend payouts, and 4) higher levels of information asymmetry.     

A comparison of value relevance of accounting information in different segments of the Chinese stock market

This paper investigates the difference in the value relevance between the accounting information prepared and audited under the Chinese GAAP for A-share investors and under the international accounting standards (IAS) for B-share investors in the Chinese stock market. The study reports three primary findings. First, accounting information influences the pricing process in both the A-share market and the B-share market. Second, the accounting information in the B-share market is more value relevant than that in the A-share market, as expected. Finally, the value relevance level of accounting information in the A-share market was low in earlier years, peaked in 1996, and then decreased due to changes in the disclosure environment. However, the value-relevance level of accounting information in the B-share market had no substantial changes. Using a constant sample, control variables on firm features, and measures of traders' behavior, we obtain robust results. These findings have implications for policymakers on recent moves toward replacing local GAAP with the IAS.     

Stock market liberalization and return volatility: Evidence from the emerging market of Sri Lanka

This study examines the impact of liberalization of the Sri Lankan stock market on return volatility. We specify GARCH and TGARCH models of volatility, and estimate them using 16 years of weekly returns for the period from 1985 to 2000. The results show that liberalization of the market to foreign investors significantly increased the return volatility in the Colombo Stock Exchange. Both conditional and unconditional volatility measures are the highest in the liberalization period. Negative return shocks lead to lower volatility suggesting that there is no leverage effect, and this appears to reflect the very low levels of leverage used by Sri Lankan companies.     

Stock price reactions to earnings announcements: evidence from Chinese markets

We examine the stock price reactions to changes in earnings per share (EPS) in the Chinese stock markets. We find that domestic A-share investors do not correctly anticipate the changes in earnings and fail to adjust new earnngs information quickly, but international B-share investors can predict earnings changes better than A-share investors. As a result, abnormal returns (ARs) can be obtained by trading on the earnings information, but for A shares only. An explanation is that most A-share holders are individuals with short-term investment horizon while most B-share holders are large institutions that trade on more detailed and accurate financial information not immediately available to A-share holders.     

Market integration and currency risk in Asian emerging markets

Most of the Asian emerging stock markets started to liberalize their markets in 1990s. In this paper, I examine whether those markets have become integrated with world stock market since the 1990s by estimating and testing a dynamic version of international CAPM (ICAPM) in the absence of purchasing power parity (PPP) using a parsimonious multivariate GARCH-in-Mean (MGARCH-M) approach. I also investigate to what extent the liberalization process has affected the cost of capital and price volatility for each market. The empirical results show that Philippines was segmented from the world stock market before its liberalization date, but no evidence of market segmentation is found for the other five markets (India, Korea, Malaysia, Taiwan, and Thailand) before their liberalization dates. However, all six markets have become integrated after opening up their markets to foreign investors. In addition, the estimated risk premia are lower after the liberalization, indicating that the liberalization process has reduced the cost of capital for their domestic firms. Moreover, there is no evidence of extra market volatility introduced by capital market liberalization, and on the contrary, the markets have become more stabilized through the liberalization process.     

A note on foreigners’ trading and price effects across firms

We study the investment behavior of foreign investors in association with an equity market liberalization, and find a strong link between foreigners’ trading and local market returns. In the period following the liberalization, net purchases by foreign investors induced a permanent increase in stock prices, suggesting that local firms reduced their cost of equity capital. We also find a strong link between a firm’s fraction of foreign ownership and the magnitude of the cost reduction. Foreign investors seem to prefer large and well-known firms, and these firms realize the largest reduction in capital cost. Furthermore, our analysis suggests that foreigners increase their net holding in firms that have recently performed well. Analyzing foreigners’ performance, we find very little evidence of informed trading, suggesting that risk sharing is the most plausible explanation for the reduction of the cost of equity capital.     

Stock market liberalization and operating performance at the firm level

I use firm-specific measures of openness to foreign investors to study the impact of stock market liberalization on firm-level operating performance. In a sample of over 1,100 firms from 28 countries, firms with stocks that are open to foreign investors experience higher growth, greater investment, greater profitability, greater efficiency, and lower leverage. Strategies to address potential endogeneity suggest that the observed relation reflects, at least in part, a causal effect of openness on operating performance.     

CROSS-AUTOCORRELATION BETWEEN A SHARES AND B SHARES IN THE CHINESE STOCK MARKET

Listed companies in China, upon meeting certain requirements, can issue two types of shares: A shares and B shares. Local investors in China can only buy and sell A shares, while foreign investors can only buy and sell B shares. We argue that foreign investors may receive news about China faster than domestic Chinese investors because of information barriers in China. Since foreigners participate in the B-share market, the price movements of B shares should reflect the common information that the foreigners have. Rational A-share investors can therefore condition their trading decisions on the previous price movements of B shares. As a result, returns on B shares should lead the returns on A shares. Using daily prices of A and B shares, we demonstrate that returns of B shares are correlated with those of A shares and that this correlation depends on the information transmission mechanism at work. The pattern of the asymmetric cross-autocorrelation is robust to the inclusion of lagged realized returns and trading volumes.     

The Information Transmission Effect and Asset Prices: Evidence from the China B-Share Discount

ABSTRACT

We construct a model based on market microstructure and examine the information transmission effect of equity prices in A-share and B-share markets in China. The data on foreign share discounts raise a question: How are asset prices determined if uninformed foreign traders obtain signals by observing public information? Our investigation on the measure of the information transmission effect presents a substantial segment of the cross-sectional variation in B-share discounts and finds that the information transmission effect plays a critical role in explaining how foreign share discounts become more contractive.     

THE ROLE OF ACCOUNTING INFORMATION IN STOCK MARKET LIBERALIZATION: EVIDENCE FROM KOREA

Stock market liberalization is a decision by a country’s government to allow foreigners to buy securities in that country’s capital market. This study examines how the liberalization of the Korean stock market affected stock price behavior and changed the role of accounting information for investment decisions. The Korean stock market opened its door to foreign investment in 1991. Prior to this, market inefficiencies, such as the superfluous co-movement of stock prices with industry or market indices or investment based on rumor and speculation, were widespread. Since the opening of the stock market to foreigners, a more rational pricing behavior has emerged. This setting provides a unique opportunity to investigate how stock price behavior has changed with market liberalization and what was the role of accounting information in this process. Our results indicate that the co-movement behavior of stock prices by industry decreased and stock price differentiation based on individual firm characteristics increased after market liberalization. The results also show that the explanatory power of accounting numbers increased after market liberalization. Overall, the results imply that foreign investors contributed to the improvement of market efficiency with the opening up of capital markets in Korea. We believe that our results provide useful evidence to other capital markets that are in a similar situation.
